Authors: Liu Xujia , Jiang Zehua , Zhang Guihua , Ng Tsz Kin , Wu Zhenggen
Published: February 2021

Background

Genetic association of uncoupling proteins (UCPs) variants with the susceptibility of diabetic retinopathy (DR) in diabetes mellitus (DM) patients has been reported but with controversy. Here we aimed to conduct a meta-analysis to confirm the association of different UCPs variants with DR.

Methods

Three databases (Medline Ovid, Embase Ovid and CENTRAL) were applied in the literature search. Five genetic models, including allelic, homozygous, heterozygous, dominant and recessive models, were evaluated. Odds ratios (OR) were estimated under the random or fixed-effects models. Subgroup analyses, publication bias and sensitivity analyses were also conducted.

Results

Eleven studies on 2 UCPs variants (UCP1rs1800592 andUCP2rs659366) were included. Our meta-analysis showed thatUCP1rs1800592 was not associated with DR in type-2 DM patients, andUCP2rs659366 also showed no association with DR. In the subgroup analyses on the stage of DR, allele G ofUCP1rs1800592 significantly increased the susceptibility of proliferative diabetic retinopathy (PDR) in type-2 DM patients in the allelic (OR = 1.26,P = 0.03) and homozygous models (OR = 1.60,P = 0.04). Subgroup analysis on ethnicity did not found any significant association of rs1800592 and rs659366 with DR.

Conclusion

Our meta-analysis confirmed the association ofUCP1rs1800592 variant with PDR in patients with type-2 DM, suggesting its potential as a genetic marker for PDR prediction in population screening.

Authors: Alaofè Halimatou , Hounkpatin Waliou Amoussa , Djrolo Francois , Ehiri John , Rosales Cecilia
Published: February 2021

Background

Type 2 diabetes (T2D) is becoming an epidemic with significant disability and premature death in Sub-Saharan Africa, including Benin. However, little is known about the level of knowledge, attitude, and practice (KAP) necessary for diabetic patients to enhance therapeutic outcomes and prevent diabetes complications. The study aimed to assess patients’ KAP levels and identify the factors associated in Cotonou, southern Benin.

Methods

A cross-sectional study was conducted from July to August 2019 among 300 diabetic patients from four health centers. Data was collected using validated questionnaires. KAP levels were determined by calculating the scores, and multivariate logistic regression was used to explore factors influencing KAP scores.

Results

About 53, 52, and 47% of all patients had good knowledge, attitude, and practice towards diabetes. In logistic regression, factors such as being female, married, educated, government/non-government employee, and longer duration of diabetes were significantly associated with good knowledge. Being married, having a longer duration of diabetes, and good knowledge were significantly associated with a good attitude while being educated, having a longer duration of diabetes, and good knowledge with good practice.

Conclusions

Lack of knowledge, poor attitude, and inadequate practice were found in this surveyed community, suggesting a need for structured educational programs to assist diabetic patients. However, education should be considered a priority for male, newly diagnosed, and uneducated patients.

Authors: Jiang Yuancong , Chen Qin , Shao Yi , Gao Zhenzhen , Jin Ming , Gao Bingqiang , Zhou Bo , Yan Sheng
Published: February 2021

Background

The prognostic value of external vs internal pancreatic duct stents after pancreaticoduodenectomy remains controversial. This study aimed to evaluate the benefits of external and internal stents using the Fistula Risk Score system with regard to the incidence of clinically relevant postoperative pancreatic fistula.

Methods

A total of 382 patients who underwent pancreaticoduodenectomy with duct to mucosa pancreaticojejunostomy were retrospectively enrolled from January 2015 to October 2019. The receiver operating characteristic curve was performed for subgroup analysis of the patients at different levels of risk for pancreatic fistula.

Results

There were no significant differences in terms of pancreatic fistula or other postoperative complications. According to the receiver operating characteristic curve threshold of 3.5, 172 patients with a Fistula Risk Score ≥ 4 and 210 patients with a Fistula Risk Score < 4 were divided into separate groups. The number of valid cases was insufficient to support the subsequent research in patients with a Fistula Risk Score < 4. In patients with a Fistula Risk Score ≥ 4, the use of an external pancreatic duct stent was significantly more effective than the use of an internal stent, especially with regard to the risk for pancreatic fistula (Grade C) (P = 0.039), at ameliorating the incidence of clinically relevant postoperative pancreatic fistula (P = 0.019). Additionally, the incidence of lymphatic leakage was significantly higher in the external stent group compared with the internal stent group (P = 0.040).

Conclusions

Compared with internal stents, the use of an external stent could reduce the incidence of clinically relevant postoperative pancreatic fistula in patients with a Fistula Risk Score ≥ 4. More large-scale prospective clinical trials are warranted to further clarify our results.
A modified technique of transanal specimen extraction in the laparoscopic anterior rectal resection for upper rectal or lower sigmoid colon cancer: a retrospective study
Authors: Yu Si , Ji Yong , Luo Tedong , Xu Pengjie , Zhen Zuojun , Deng Jianzhong
Published: February 2021

Background

In recent years, natural orifice specimen extraction surgery (NOSES) has become a field of special interest for colorectal surgeons. Some researchers have reported transanal specimen extraction in the laparoscopic anterior rectal resection, including intersphincteric resection (ISR) and rectal eversion-resection. However, these surgical procedures have certain limitations. Based on the proven expertise in laparoscopic surgery, our center has developed a modified technique of transanal specimen extraction. The aim of this study was to investigate the safety and feasibility of a modified technique of transanal specimen extraction in the laparoscopic anterior rectal resection.

Methods

From January 2011 to January 2014, the patients with upper rectal or lower sigmoid colon cancer who had undergone laparoscopic anterior rectal resection with specimen extraction by a modified transanal technique were enrolled in the observation group, and the patients who had undergone laparoscopic anterior rectal resection with specimen extraction via an abdominal incision by the same surgeons during the same period were enrolled in the control group.

Results

A total of 36 patients were included in the observation group and 128 patients were included in the control group. There were no significant differences (P > 0.05) between the two groups in terms of the mean operative time [144 ± 10 min vs. 141 ± 11 min], mean intraoperative blood loss [63 ± 6 ml vs. 61 ± 7 ml], and the mean time to anal exhaust [67 ± 7 h vs. 65 ± 8 h]. However, there were significant differences (P < 0.05) between the two groups in terms of the mean postoperative Visual Analogue Scale (VAS) pain scores [3.4 ± 1.1 vs. 4.5 ± 1.2], mean postoperative hospital stay [6.0 ± 1.1 days ± vs. 7.2 ± 1.2 days], and incidence of postoperative complications (4/36 vs. 15/128). Long-term follow-up results showed that there was no significant difference (P > 0.05) between the two groups in terms of the 3- or 5-year overall survival.

Conclusions

The modified technique of transanal specimen extraction in the laparoscopic anterior rectal resection fulfilled the principle of no-neoplasm touch technique, with advantages, such as minimal trauma, rapid recovery, and fewer complications. Long-term follow-up results also showed satisfactory oncological outcomes.
The gut microbiota and colorectal surgery outcomes: facts or hype? A narrative review
Authors: Agnes Annamaria , Puccioni Caterina , D’Ugo Domenico , Gasbarrini Antonio , Biondi Alberto , Persiani Roberto
Published: February 2021

Background

The gut microbiota (GM) has been proposed as one of the main determinants of colorectal surgery complications and theorized as the “missing factor” that could explain still poorly understood complications. Herein, we investigate this theory and report the current evidence on the role of the GM in colorectal surgery.

Methods

We first present the findings associating the role of the GM with the physiological response to surgery. Second, the change in GM composition during and after surgery and its association with colorectal surgery complications (ileus, adhesions, surgical-site infections, anastomotic leak, and diversion colitis) are reviewed. Finally, we present the findings linking GM science to the application of the enhanced recovery after surgery (ERAS) protocol, for the use of oral antibiotics with mechanical bowel preparation and for the administration of probiotics/synbiotics.

Results

According to preclinical and translational evidence, the GM is capable of influencing colorectal surgery outcomes. Clinical evidence supports the application of an ERAS protocol and the preoperative administration of multistrain probiotics/synbiotics. GM manipulation with oral antibiotics with mechanical bowel preparation still has uncertain benefits in right-sided colic resection but is very promising for left-sided colic resection.

Conclusions

The GM may be a determinant of colorectal surgery outcomes. There is an emerging need to implement translational research on the topic. Future clinical studies should clarify the composition of preoperative and postoperative GM and the impact of the GM on different colorectal surgery complications and should assess the validity of GM-targeted measures in effectively reducing complications for all colorectal surgery locations.
Mucormycosis originated total maxillary and cranial base osteonecrosis: a possible misdiagnosis to malignancy
Authors: Park Young Long , Cho Sura , Kim Jin-Woo
Published: February 2021

Background

This is a case of mucormycosis originated osteonecrosis of the maxilla extended to the cranial base, initially suspected of malignancy. The patient was first suspected with osteolytic sarcomatous lesion but was later diagnosed with total maxillary necrosis and cranial base through biopsy-proven invasive mucormycosis.

Case presentation

A 71-year-old male was presented with unknown total maxillary osteonecrosis. CT and MRI results showed extensive osteolytic change with bone destruction of the cranial base, and PET-CT showed irregular hypermetabolic lesion in the area suspected of malignancy. The first biopsy results only presented tissue inflammation. Thus, several further endoscopic biopsy were performed through posterior pharyngeal wall. The patient was eventually diagnosed with mucormycosis and associated osteomyelitis with subsequent bone necrosis. With confirmed diagnosis, partial maxillectomy of the necrosed bone was performed under general anesthesia. At the 4 week follow-up, the patient showed full mucosal healing and no recurrence or aggravation of the maxilla and cranial base lesion was observed.

Conclusions

Accurate diagnosis of atypical symptoms, timely diagnosis, and proper combination therapy of surgical intervention, antifungal agent, and antibiotic use for skull base osteomyelitis are all critical for proper treatment planning. In addition, biopsy and CT scans are essential in differentiating osteonecrosis from malignancy.

Authors: Mustafa Imtiaz , Faisal Muhammad Naeem , Hussain Ghulam , Muzaffar Humaira , Imran Muhammad , Ijaz Muhammad Umar , Sohail Muhammad Umar , Iftikhar Arslan , Shaukat Arslan , Anwar Haseeb
Published: February 2021

Background

Euphorbia helioscopia, conventionally known as sun spurge, has been used as a traditional medicine to treat different diseases owing to its reported antitumor, antiviral and antioxidant activities.

Methods

The current research was formulated to assess the in-vitro antioxidant and antidiabetic ability ofEuphorbia helioscopiasubsequent to the phytochemical analysis of its various extracts. For this purpose, methanol, ethanol and aqueous extracts were prepared using the whole dried plant. Phytochemical analysis of the extracts was done to evaluate the total flavonoid components (TFC) and total phenolic components (TPC) in the extracts. A total of seven phenolic and three flavonoid contents were documented and quantified using HPLC. Antioxidant values were found by DPPH●assay, FRAP and ABTS assays. The antidiabetic potential of the extracts was evaluated by measuring the inhibition ability of the activity of enzymes α amylase and α glucosidase.

Results

After analyzing statistically, the results showed that methanolic extract possesses the highest TFC and TPC values while aqueous extract encompassed the lowest level of these contents.Invitroresults showed that methanolic extract of theEuphorbia helioscopiahas the maximum antioxidant capability since it showed the highest scavenging ability towards the DPPH●(IC50value = 0.06 ± 0.02 mg/ml), FRAP (758.9 ± 25.1 μMFe+ 2/g), and ABTS (689 ± 25.94 μMTEq/g) due to the presence of high TPC (24.77 ± 0.35 mgGAEq/g) and TFC (17.95 ± 0.32 mgQEq/g) values. Antidiabetic activity in terms of inhibition potential of α amylase and α glucosidase activity was also observed maximum in methanolic extract having lowest IC50value (0.4 ± 0.01 mg/ml and 0.45 ± 0.01 mg/ml respectively) and minimum in the aqueous extract (IC50value = 0.57 ± 0.02 mg/ml and 0.76 ± 0.1 mg/ml respectively).

Conclusion

The experiment outcomes have shown thatEuphorbia helioscopiaextracts used in the current study contain antioxidant and antidiabetic activities; however, it is highest in its methanolic extract. The presence of the same trend towards the highest antidiabetic activity of the methanolic extract in terms of maximum inhibiting activity of α amylase and α glucosidase enzymes suggests a close association of TFC and TPC in minimizing diabetes.
A retrospective quantitative implementation evaluation of Safer Opioid Prescribing, a Canadian continuing education program
Authors: Sud Abhimanyu , Doukas Kathleen , Hodgson Katherine , Hsu Justin , Miatello Amber , Moineddin Rahim , Paton Morag
Published: February 2021

Background

Continuing health professions education (CHPE) is an important policy intervention for the opioid epidemic. Besides effectiveness or impact, health policy implementation should be studied to understand how an intervention was delivered within complex environments. Implementation outcomes can be used to help interpret CHPE effects and impacts, help answer questions of “how” and “why” programs work, and inform transferability. We evaluated Safer Opioid Prescribing (SOP), a national CHPE program, using implementation outcomes of reach, dose, fidelity, and participant responsiveness.

Methods

We conducted a retrospective quantitative implementation evaluation of the 2014–2017 cohorts of SOP. To measure reach and dose, we examined participation and completion data. We used Ontario physician demographic data, including regulatory status with respect to controlled substances, to examine relevant trends. To measure fidelity and participant responsiveness, we analyzed participant-provided evaluations of bias, active learning, and relevance to practice. We used descriptive statistics and measures of association for both continuous and categorical variables. We used logistic regression to determine predictors of workshop participation and analysis of covariance to examine variation in satisfaction across different-sized sessions.

Results

Reach: In total, there were 472 unique participants, 84.0% of whom were family physicians. Among Ontario physician participants, 90.0% were family physicians with characteristics representative of province-wide demographics. Dose: Webinar completion rate was 86.2% with no differences in completion based on rurality, gender, or controlled substance prescribing status with medical regulatory authorities. Fidelity and participant responsiveness: Nearly all participants rated the three webinars and workshop as balanced, and each element of SOP was also rated as highly relevant to clinical practice.

Conclusions

This evaluation demonstrates that Safer Opioid Prescribing was implemented as intended. Over a short period and without any external funding, the program reached more than 1% of the Ontario physician workforce. This suggests that the program may be a good model for using virtual CHPE to reach a critical mass of prescribers. This study represents a methodological advance of adapting evaluation methods from health policy and complex interventions for continuing health professions education. Future studies will assess effectiveness and impact on opioid prescribing and utilization within evaluation models of complex interventions.
Genetics education program to help public health nurses improve their knowledge and enhance communities’ genetic literacy: a pilot study
Authors: Kawasaki Hiromi , Kawasaki Masahiro , Iki Tomoko , Matsuyama Ryota
Published: February 2021

Background

As human genetics knowledge develops, public genetic literacy needs to be increased, though the educational capacity for this purpose has not yet been fully developed. Under this circumstance, the daily work of public health nurses can be viewed as an opportunity to enhance public genetic literacy. However, in Japan, there is not only a lack of public knowledge of human genomics but also a lack of public health nurses’ recognition about genomic literacy. A short-term education program was implemented as a pilot study. This study aimed to examine the effectiveness of the program to support public health nurses’ activity aimed at promoting health services-related genetic literacy.

Methods

The genetics education program was implemented in December 2019, in Kagoshima, Japan. Twenty-three public health nurses cooperated with the research. The program was composed of a case study on consultation, a lecture on hereditary diseases, and a discussion on the role of public health nurses. Familial hypercholesterolemia was used as the topic of the case study. We evaluated scores for cognition, affect, and psychomotor characteristics related to their learning goals before and after the program using Wilcoxon signed-rank tests. Answers in the consultation were qualitatively analyzed.

Results

The mean cognitive score, capturing provision of explanations of hereditary disease, was 6.3 before the program but increased significantly to 9.3 after the program (p < 0.001). For the affective score, the goal of which was deepening interest in human genetics, the mean score increased significantly from 8.5 before to 11.0 after (p < 0.001). For the psychomotor score, addressing the need for genetic consultation, the mean score increased significantly from 4.4 before to 8.1 after (p < 0.001). Prominent themes extracted from descriptions on the worksheet post training included, “providing advice and accurate information on genetic disorders” and “referral to a specialized organization.”

Conclusions

Our findings indicated that this education program helps public health nurses be positively involved in human genetic disorders. Thus, they may connect to their local community to provide accurate genetics knowledge and advice for health management and promoting genetic literacy.

Authors: Yazdi-Feyzabadi Vahid , Nakhaee Nouzar , Mehrolhassani Mohammad Hossein , Naghavi Soheila , Homaie Rad Enayatollah
Published: February 2021

Background

Patients’ non-adherence with medical orders of physicians in outpatient clinics can lead to reduced clinical effectiveness, inadequate treatment, and increased medical care expenses. This study was conducted to develop and validate a questionnaire to determine the reasons for patients’ non-adherence with physicians’ medical orders.

Methods

A sequential exploratory mixed-method study was conducted in two stages. The first stage comprised a qualitative stage to generate the primary items of the questionnaire. This stage provided findings of two sub-stages comprising a literature review and the findings of a qualitative conventional content analysis of 19 semi-structured interviews held with patients, physicians, and managers of the outpatient clinics in Kerman, an area located in southeastern Iran. The second stage comprised a quantitative study aiming evaluation of the instrument psychometric properties, including the face, content, construct, and reliability assessment of the questionnaire. Construct validity assessment was evaluated using exploratory factor analysis (EFA). The reliability assessment was done using assessing internal consistency (Cronbach’s alpha). To assess the construct validity of the questionnaire, four hundred and forty patients referred to outpatient clinics in Kerman were selected using stratified convenience sampling to fill out the questionnaire. The sample size was calculated using the Cochran formula. Qualitative and quantitative data were analyzed by MAXQDA 10 and Stata version 14, respectively.

Results

The primary items contained 57 items, of which 42 met the minimum acceptable value of 0.78 for item-level content validity index (I-CVI = 1 for 24 items and I-CVI = 0.8 for 18 items). Item-level content validity ratio (I-CVR) was confirmed for 18 items with a minimum acceptable value of 0.99 for five experts. Finally, 18 items obtained the acceptable value for both I-CVI and I-CVR indicators and were confirmed. Using EFA, four factors (intrapersonal-psychological, intrapersonal-cognitive, provider-related, and socio-economic reasons) with 18 items and Cronbach’s alpha coefficient of 0.70, 0.66, 0.73, and 0.71, respectively, were identified and explained 51% of the variance. The reliability of the questionnaire (r = 0.70) was confirmed.

Conclusion

The questionnaire with four dimensions is a valid and reliable instrument that can help determine the perceived reasons for non-adherence with medical orders in the outpatient services system.
Determinants of caregiver satisfaction with child neurodevelopmental assessment in neuropaediatric clinics
Authors: Kjærandsen Katarina Smejda , Brøndbo Per Håkan , Halvorsen Marianne Berg
Published: February 2021

Background

In addition to patient evaluations, caregiver evaluations and experiences are important indicators of the quality of health services. The aim of this study was to examine determinants of caregiver satisfaction with and perceived benefit of child neurodevelopmental assessment in neuropaediatric clinics.

Methods

The study was conducted among caregivers of children and adolescents aged 4–18 years (N = 330) referred for neurodevelopmental assessment in two neuropaediatric clinics in the specialised health service in Northern Norway. The Generic Short Patient Experiences Questionnaire (GS-PEQ) for child psychiatric outpatient patients was distributed to caregivers immediately following the assessment, and two of its items were used as measurements of caregiver satisfaction with and perceived benefit of the assessment.

Results

Caregiver satisfaction with the assessment was correlated with a better general level of function in the child, higher socioeconomic status, Norwegian mother tongue, referral from a specialist, and the respondent being a woman. Higher perceived benefit of the assessment was correlated with higher socioeconomic status, Norwegian mother tongue, and younger age of the child. Regression analysis revealed that caregivers’ perception that the assessment was suited to their child’s situation and that there was good cooperation with other public services (e.g., primary care and social/educational services) seemed more fundamental to caregiver satisfaction with neuropaediatric clinics’ services than any background variable. Younger age of the child, in addition to caregivers’ perception that the assessment was suited to their child and receiving sufficient information about the child’s diagnosis/afflictions, were essential to the perceived benefit of the assessment.

Conclusions

Caregiver satisfaction with child neurodevelopmental assessment in neuropaediatric clinics partly depends on variables not related to the assessment experience per se. An assessment that was suited to the child, good cooperation with other public services such as primary health care and social/educational services, and giving sufficient information about the child’s diagnosis are essential to an overall positive caregiver evaluation of neurodevelopmental assessments.

Published: February 2021

Background

Patient satisfaction is one proxy indicator of the health care quality; however, enhancing patient satisfaction in low-income settings is very challenging due to the inadequacy of resources as well as low health literacy among patients. In this study, we assess patient satisfaction and its correlates in a tertiary public hospital in Nepal.

Methods

We conducted a cross sectional study at outpatient department of Bhaktapur Hospital of Nepal. To recruit participants for the study, we applied a systematic random sampling method. Our study used a validated Patient Satisfaction Questionnaire III (PSQ-III) developed by RAND Corporation including various contextual socio-demographic characteristics. We calculated mean score and percentages of satisfaction across seven dimensions of patient satisfaction. To determine the association between various dimensions of patient satisfaction and socio-demographic characteristics of the patient, we used a multi-ordinal logistic regression.

Results

Among 204 patients, we observed a wide variation in patient satisfaction across seven dimensions. About 39% of patients were satisfied in the dimension of general satisfaction, 92% in interpersonal manner, and 45% in accessibility and convenience. Sociodemographic factors such as age (AOR: 6.42; CI: 1.30–35.05), gender (AOR: 2.81; CI: 1.41–5.74), and ethnicity (AOR: 0.26; CI: 0.08–0.77) were associated with general satisfaction of the patients. Other sociodemographic variables such as education, occupation, and religion were associated with a majority of the dimensions of patient satisfaction (p < 0.05). Age was found to be the strongest predictor of patient satisfaction in five out of seven dimensions.

Conclusions

We concluded that patient satisfaction varies across different dimensions. Therefore, targeted interventions that direct to improve the dimensions of patient satisfaction where the proportion of satisfaction is low are needed. Similar studies should be conducted regularly at different levels of health facilities across the country to capture a wider picture of patient satisfaction at various levels.
Enriching the nutritive value of marigold (Tagetes erecta L) crop residues as a ruminant feed by lactic acid bacteria during ensilage
Authors: Hou Zhijiang , Liu Jianyong , Cai Ming , Liu Yanpei , Mu Lan , Gao Yuee , Wanapat Metha , Huang Bizhi
Published: February 2021

Background

Marigold (Tagetes erecta L) accounts for over half of the world’s loose flower production, and marigold crop residue (MCR) are abundantly available and should be used as a forage. In this study, MCR from the last commercial flower pickings was ensilaged with lactic acid bacteria (LAB) and the shift in their volatile organic compounds (VOCs) profiles was monitored. Samples were collected at 6 different times during ensilage (3, 6, 9, 12, 15, 30 days) to determine and quantify the VOCs changes using a solid-phase microextraction (SPME) technique and gas chromatography – mass spectrometry (GC-MS).

Results

After 30 days, the caryophyllene and piperitone, which account for 14.7 and 12.1% of total VOCs, decreased by 32.9 and 9.6% respectively, alcohols increased from 2.8 to 8.1%, and the acetic acid content increased by 560%.

Conclusion

We have confirmed LAB can degrade the content of terpenes and enhance the content of alcohols and acids in MCR, which was for the first time on terpene degradation in fodder by ensilage. These results have shed light on our understanding of how to improve fodder odor and to enhance terpene degradation by lactic acid bacteria fermentation.
Three-dimensional motion of the patella in French bulldogs with and without medial patellar luxation
Authors: Lehmann Silvia V. , Andrada Emanuel , Taszus Roxana , Koch Daniel , Fischer Martin S.
Published: February 2021

Background

French bulldogs exhibit significantly larger femoral external rotation and abduction than other breeds. We were curious as to whether this peculiar leg kinematic affects patellar motion and/or might induce medial patellar subluxation (MPSL) or medial patellar permanent luxation (MPPL). We hypothesized that the more abducted leg posture during stance causes an unusual medial pull direction of the rectus femoris muscle during stance, and that this may facilitate the occurrence of MPSL or even MPPL during locomotion. To test our hypothesis, we analyzed existing stifle-joint X-ray-sequences collected during the treadmill walk and trot of seven adult female French bulldogs. We estimated 3D-patellar kinematics using Scientific Rotoscoping.

Results

The three-dimensional motion of the patella comprises rotations and translations. From the seven dogs analyzed, three exhibited MPSL and one MPPL during the gait cycle. Medial patellar luxation (MPL) occurred mostly around toe-off in both gaits studied.

Patellar position was generally not gait-related at the analyzed timepoints. In dogs with MPL, the patella was placed significantly more distally (p = 0.037) at touch-down (TD) and at midswing (p = 0.024), and significantly more medial at midswing (p = 0.045) compared to dogs without MPL.

Conclusions

Medial patellar luxation seems to be the consequence of the far from parasagittal position of the stifle joint during stance due to a broad trunk, and a wide pelvis. This peculiar leg orientation leads to a medial sideway pull caused by the rectus femoris muscle and the quadriceps femoris and may initiate plastic deformation of the growing femur and tibia. Thus, a way to avoid MPL could be to control breeding by selecting dogs with lean bodies and narrow pelvis. Actual breeding control programs based on the orthopedic examination are susceptible to errors. Systematic errors arise from the fact that the grading system is highly dependent on the dog’s condition and the veterinarians’ ability to perform the palpation on the stifle. Based on our results, the position of the patella at TD, or even perhaps during stand might offer a possibility of an objective radioscopic diagnostic of the MPL.
Does pulmonary subspecialty referral from primary care affect the adherence to vaccination recommendations in COPD patients?
Authors: Ehteshami-Afshar Solmaz , Crothers Kristina , Rodwin Benjamin , Bade Brett , Brandt Cynthia , Akgün Kathleen M.
Published: February 2021

The importance of vaccinations for COPD patients has been previously described. However, there is still a gap between guideline recommendations and the implementation of preventive care delivery for these patients. Specially, the rise of SARS-CoV-2 pandemic has made the significance of vaccination adherence more critical to address. Our study showed that referral to pulmonary clinic is associated with increased odds of receiving influenza (OR = 1.97, [95% CI 1.07, 3.65]) and pneumococcal vaccinations (PCV13 OR = 3.55, [1.47, 8.54]; PPSV23 OR = 4.92, [1.51, 16.02]). These data suggest that partnerships between primary care physicians and pulmonologists can potentially improve the vaccination rates for patients with COPD.

Published: February 2021

Background

Chinese Yunnan Province, located in the Yunnan–Guizhou Plateau, is a famous tourist paradise where acute high-altitude illness common occurs among lowland people visitors due to non-acclimatization to the acute hypobaric hypoxia (AHH) conditions. Traditional Chinese medicine, such as Qi-Long-Tian (QLT) formula, has shown effectiveness and safety in the treatment of acute high-altitude diseases. The aim of this study was to clarify the therapeutic mechanisms of this traditional formula using a rat model in a simulated plateau environment.

Methods

Following testing, lung tissue samples were evaluated by hematoxylin–eosin staining and for biochemical characteristics. mRNA-Seq was used to compare differentially expressed genes in control rats, and in rats exposed to AHH and AHH with QLT treatment.

Results

Inflammation-related effectors induced following QLT treatment for AHH included MMP9 and TIMP1, and involved several phosphorylation signaling pathways implicated in AHH pathogenesis such as PI3K/AKT and MAPK signaling.

Conclusion

This study provides insights into the major signaling pathways induced by AHH and in the protective mechanisms involved in QLT formula activity.
Prognostic and predictive value of FCER1G in glioma outcomes and response to immunotherapy
Authors: Xu Houshi , Zhu Qingwei , Tang Lan , Jiang Junkun , Yuan Huiwen , Zhang Anke , Lou Meiqing
Published: February 2021

Purpose

Glioma is the most prevalent malignant form of brain tumors, with a dismal prognosis. Currently, cancer immunotherapy has emerged as a revolutionary treatment for patients with advanced highly aggressive therapy-resistant tumors. However, there is no effective biomarker to reflect the response to immunotherapy in glioma patient so far. So we aim to assess the clinical predictive value of FCER1G in patients with glioma.

Methods

The expression level and correlation between clinical prognosis and FER1G levels were analyzed with the data from CGGA, TCGA, and GEO database. Univariate and multivariate cox regression model was built to predict the prognosis of glioma patients with multiple factors. Then the correlation between FCER1G with immune cell infiltration and activation was analyzed. At last, we predict the immunotherapeutic response in both high and low FCER1G expression subgroups.

Results

FCER1G was significantly higher in glioma with greater malignancy and predicted poor prognosis. In multivariate analysis, the hazard ratio of FCER1G expression (Low versus High) was 0.66 and 95 % CI is 0.54 to 0.79 (P < 0.001), whereas age (HR = 1.26, 95 % CI  1.04–1.52), grade (HR = 2.75, 95 % CI 2.06–3.68), tumor recurrence (HR = 2.17, 95 % CI  1.81–2.62), IDH mutant (HR = 2.46, 95 % CI 1.97–3.01) and chemotherapeutic status (HR = 1.4, 95 % CI  1.20–1.80) are also included. Furthermore, we illustrated that gene FCER1G stratified glioma cases into high and low FCER1G expression subgroups that demonstrated with distinct clinical outcomes and T cell activation. At last, we demonstrated that high FCER1G levels presented great immunotherapeutic response in glioma patients.

Conclusions

This study demonstrated FCER1G as a novel predictor for clinical diagnosis, prognosis, and response to immunotherapy in glioma patient. Assess expression of FCER1G is a promising method to discover patients that may benefit from immunotherapy.

As malaria endemic countries strive towards elimination, intensified spatial heterogeneities of local transmission could undermine the effectiveness of traditional intervention policy.

The dynamic nature of large-scale and long-term malaria heterogeneity across Brazilian Amazon basin were explored by (1) exploratory analysis of Brazil’s rich clinical malaria reporting database from 2004 to 2018, and (2) adapting Gini coefficient to study the distribution of malaria cases in the region.

Results

As transmission declined, heterogeneity increased with cases clustering into smaller subpopulations across the territory. In 2004, the 1% of health units with the greatest number of cases accounted for 46% of all reported Plasmodium vivax cases, whereas in 2018 52% of P. vivax cases occurred in the top 1% of health units. Plasmodium falciparum had lower levels of transmission than P. vivax, and also had greater levels of heterogeneity with 75% of cases occurring in the top 1% of health units. Age and gender stratification of cases revealed peri-domestic and occupational exposure settings that remained relatively stable.

Conclusion

The pathway to decreasing incidence is characterized by higher proportions of cases in males, in adults, due to importation, and caused by P. vivax. Characterization of spatio-temporal heterogeneity and risk groups can aid stratification for improved malaria control towards elimination with increased heterogeneity potentially allowing for more efficient and cost-effective targeting. Although distinct epidemiological phenomena were clearly observed as malaria transmission declines, the authors argue that there is no canonical path to malaria elimination and a more targeted and dynamic surveillance will be needed if Brazil decides to adopt the elimination target.
An integrated analysis of spatial access to the three-tier healthcare delivery system in China: a case study of Hainan Island
Authors: Wang Xiuli , Seyler Barnabas C. , Han Wei , Pan Jay
Published: February 2021

Background

Access to healthcare is critical for the implementation of Universal Health Coverage. With the development of healthcare insurance systems around the world, spatial impedance to healthcare institutions has attracted increasing attention. However, most spatial access methodologies have been developed in Western countries, whose healthcare systems are different from those in Low- and Middle-Income Countries (LMICs).

Methods

Hainan Island was taken as an example to explore the utilization of modern spatial access techniques under China’s specialized Three-Tier Health Care Delivery System. Healthcare institutions were first classified according to the three tiers. Then shortest travel time was calculated for each institution’s tier, overlapped to identify eight types of multilevel healthcare access zones. Spatial access to doctors based on the Enhanced Two-Step Floating Catchment Area Method was also calculated.

Results

On Hainan Island, about 90% of the population lived within a 60-min service range for Tier 3 (hospital) healthcare institutions, 80% lived within 30 min of Tier 2 (health centers), and 75% lived within 15 min of Tier 1 (clinics). Based on local policy, 76.36% of the population living in 48.52% of the area were able to receive timely services at all tiers of healthcare institutions. The weighted average access to doctors was 2.31 per thousand residents, but the regional disparity was large, with 64.66% being contributed by Tier 3 healthcare institutions.

Conclusion

Spatial access to healthcare institutions on Hainan Island was generally good according to travel time and general abundance of doctors, but inequity between regions and imbalance between different healthcare institution tiers exist. Primary healthcare institutions, especially in Tier 2, should be strengthened.
Working towards universal health coverage: a qualitative study to identify strategies for improving student enrolment for the pre-service training of nurses, midwives and community health workers in Nigerian health training institutions
Authors: Okereke Ekechi , Ahonsi Babatunde
Published: February 2021

Background

Student enrolment processes and practices can affect the quality of pre-service training programmes. These processes and practices may have serious implications for the quality and quantity of students within health training institutions, the quality of education for prospective health workers and consequently health workforce performance. This study assessed current student enrolment processes and practices for nurses, midwives and community health workers within health training institutions in two Nigerian states, so as to identify strategies for improving student enrolment for these key cadres of frontline health workers.

Methods

This study was carried out in Bauchi and Cross-River States, which are the two Human Resources for Health (HRH) project focal states in Nigeria. Utilizing a qualitative research design, 55 in-depth interviews and 13 focus group discussions were conducted with key stakeholders including students and tutors from pre-service health training institutions as well as policy-makers and public sector decision-makers from Ministries of Health, Government Agencies and Regulatory Bodies. Study participants were purposively sampled and the qualitative data were audio-recorded, transcribed and then thematically analysed.

Results

Study participants broadly described the application process to include the purchase, completion and submission of application forms by prospective students prior to participation in entrance examinations and oral interviews. The use of ‘weeding examinations’ during the student enrolment process, especially in Bauchi state, was identified as a useful quality assurance mechanism for the pre-service training programmes of frontline health workers. Other strategies identified by stakeholders to address challenges with student enrolment include sustained advocacy to counter-cultural norms and gender stereotypes vis-à-vis certain professions, provision of scholarships for trainee frontline health workers and ultimately the development as well as effective implementation of national and state-specific policy and implementation guidelines for the student enrolment of key frontline health workers.

Conclusion

While there are challenges which currently affect student enrolment for nurses, midwives and community health workers in Nigeria, this study has proposed key strategies which if carefully considered and implemented can substantially improve the status quo. These will probably have far-reaching implications for improving health workforce performance, population health outcomes and efforts to achieve universal health coverage.
Implementation of evidence-based practice and associated factors among nurses and midwives working in Amhara Region government hospitals: a cross-sectional study
Authors: Dagne Asrat Hailu , Beshah Mekonnen Haile , Kassa Bekalu Getnet , Dagnaw Eyaya Habtie
Published: February 2021

Background

Implementation of evidence-based practice is crucial to enhance quality health care, professional development, and cost-effective health service. However, many factors influence the implementation of evidence-based practice. Therefore, this study aimed to assess the implementation of evidence-based practice and associated factors among nurses and midwives.

Methods

Institutional-based cross-sectional study design was conducted to assess the implementation of evidence-based practice and associated factors from February 15 to March 15, 2019, among 790 nurses and midwives. Data were entered into EpiData version 3.1 then exported to SPSS version 20 for statistical analysis. Categorical variables were presented as frequency tables. Continuous variables were presented as descriptive measures, expressed as mean and standard deviation. Cronbach’s alpha was used to measure reliability, mean, standard deviation, and inter-items correlation of the factors. Independent variables with a probability value (P-value) of less than 0.2 in the Chi-square analysis were entered in the multivariable logistic regression model. Statistically significant associated factors were identified at probability value (P-value) less than 0.05 and adjusted odds ratio with a 95% confidence interval.

Results

The mean age of participants was 28.35 (SD ± 4.5) years. This study revealed that 34.7% (95% CI 31.5–38%) of participants implemented evidence-based practice moderately or desirably. Age of participants (AOR = 5.98, CI 1.34–26.7), barriers of implementation of evidence-based practice (AOR = 4.8, CI 2.2–10.6), the attitude of participants (AOR = 5.02, CI 1.2–21.5), nursing/midwifery work index (AOR = 3.9, CI 1.4–10.87), self-efficacy of implementation of evidence-based practice skills (AOR = 12.5, CI 5.7–27.5) and knowledge of participants (AOR = 3.06, CI 1.6–5.77) were statistically significant associated factors of implementation of evidence-based practice

Concussion

Implementation of evidence-based practice of nurses and midwives was poor. Age of participants, barriers of implementation of evidence-based practice, the attitude of participants, self-efficacy of implementation of evidence-based practice skills, nursing/midwifery work index, and knowledge of participants were found to be predictors of implementation of evidence-based practice. Insufficient time and difficulty in judging the quality of research papers and reports were the most common barriers to the implementation of evidence-based practice.

Published: February 2021

Background

Three-dimensional preoperative planning was applied for the osteosynthesis of distal radius fractures. The objective of this study was to evaluate the reproducibility of three-dimensional preoperative planning for the osteosynthesis of distal radius fractures with three-dimensional reference points.

Methods

Sixty-three wrists of 63 distal radius fracture patients who underwent osteosynthesis with three-dimensional preoperative planning were evaluated. After taking preoperative CT scans of the injured wrists, 3D images of the distal radius were created. Fracture reduction, implants choices, and placements simulation were performed based on the 3D images. One month after the surgery, postoperative CT images were taken. The reproducibility was evaluated with preoperative plan and postoperative 3D images. The images were compared with the three-dimensional coordinates of radial styloid process, volar and dorsal edges of sigmoid notch, and the barycentric coordinates of the three reference points. The reproducibility of the preoperative plan was evaluated by the distance of the coordinates between the plan and postoperative images for the reference points. The reproducibility of radial inclination and volar tilt on three-dimensional images were evaluated by intra-class correlation coefficient (ICC).

Results

The distances between the preoperative plan and the postoperative reduction for each reference point were (1) 2.1±1.3 mm, (2) 1.9±1.2 mm, and (3) 1.9±1.2 mm, respectively. The distance between the preoperative plan and postoperative reduction for the barycentric coordinate was 1.3±0.8 mm. ICCs were 0.54 and 0.54 for the volar tilt and radial inclination, respectively (P<0.01).

Conclusions

Three-dimensional preoperative planning for the osteosynthesis of distal radius fracture was reproducible with an error of about 2 mm for each reference point and the correlations of reduction shapes were moderate. The analysis method and reference points may be helpful to understand the accuracy of reductions for the three-dimensional preoperative planning in the osteosynthesis of distal radius fractures.
