Galectin-1 expression in the serum and placenta of pregnant women with fetal growth restriction and its significance
Authors: Jin Xiao-Xiao , Ying Xiang , Dong Min-Yue
Published: January 2021

Background

This study aims to investigate galectin-1 (Gal-1) expression in the serum and placenta of pregnant women with fetal growth restriction (FGR) and its significance.

Methods

Thirty-one pregnant women with single-birth FGR but without comorbidities, eight pregnant women with FGR and preeclampsia (PE), and eight pregnant women with FGR and gestational diabetes mellitus (GDM) were enrolled as the study group, while 20 pregnant women with normal singleton pregnancy in the same period were enrolled as the control group. The serum Gal-1 level was detected using an enzyme-linked immunosorbent assay (ELISA), and Gal-1 expression in the placenta was detected by western blot.

Results

The results revealed that, compared with the control group, the serum Gal-1 level decreased in the women with FGR without comorbidities, and the difference was statistically significant (P < 0.001). Compared with the control group, the difference in serum Gal-1 expression in the FGR-PE group was not statistically significant (P = 0.29). The peripheral serum Gal-1 level decreased in the FGR-GDM group compared with the control group, and the difference was statistically significant (P < 0.001). The serum Gal-1 level was positively correlated with birth weight (r2 = 0.172,P < 0.01). Compared with the control group, the Gal-1 expression level decreased in the placenta of the pregnant women with FGR without comorbidities (P < 0.05).

Conclusions

Gal-1 exhibits low expression in the serum and placenta of pregnant women with FGR. In addition, Gal-1 may be involved in the pathogenesis of FGR and could represent a new diagnostic marker of the disease.

Published: January 2021

Background

Globally, 15 million neonates are born prematurely every year, over half in low income countries (LICs). Premature and low birth weight neonates have a higher risk of intraventricular haemorrhage (IVH). There are minimal data regarding IVH in sub-Saharan Africa. This study aimed to examine the incidence, severity and timing of and modifiable risk factors for IVH amongst low-birth-weight neonates in Uganda.

Methods

This is a prospective cohort study of neonates with birthweights of ≤2000 g admitted to a neonatal unit (NU) in a regional referral hospital in eastern Uganda. Maternal data were collected from interviews and medical records. Neonates had cranial ultrasound (cUS) scans on the day of recruitment and days 3, 7 and 28 after birth. Risk factors were tabulated and are presented alongside odds ratios (ORs) and adjusted odds ratios (aORs) for IVH incidence. Outcomes included incidence, timing and severity of IVH and 28-day survival.

Results

Overall, 120 neonates were recruited. IVH was reported in 34.2% of neonates; 19.2% had low grade (Papile grades 1–2) and 15% had high grade (Papile grades 3–4). Almost all IVH (90.2%) occurred by day 7, including 88.9% of high grade IVH. Of those with known outcomes, 70.4% (81/115) were alive on day 28 and survival was not associated with IVH. We found that vaginal delivery, gestational age (GA) < 32 weeks and resuscitation in the NU increased the odds of IVH. Of the 6 neonates who received 2 doses of antenatal steroids, none had IVH.

Conclusion

In this resource limited NU in eastern Uganda, more than a third of neonates born weighing ≤2000 g had an IVH and the majority of these occurred by day 7. We found that vaginal birth, earlier gestation and need for resuscitation after admission to the NU increased the risk of IVH. This study had a high rate of SGA neonates and the risk factors and relationship of these factors with IVH in this setting needs further investigation. The role of antenatal steroids in the prevention of IVH in LICs also needs urgent exploration.
Perinatal factors influencing the neonatal hearing screening results
Authors: Kaveh Mahbod , Mirjalali Seyedeh Nastaran , Shariat Mamak , Zarkesh Mohammad Reza
Published: January 2021

Background

Previous studies have indicated that the majority of cases with “failed” results related to transient evoked otoacoustic emissions (OAE) test have the normal hearing. The present study aimed to assess the possible relationships between perinatal factors and the false-positive OAE results.

Methods

A case-control study was carried out in an Iranian Hospital in 2020. Based on the OAE results on the first day of life, newborns were divided into 2 groups; Control group included subjects with “Pass” OAE results. Every neonate with “Fail” OAE result was referred for auditory brainstem response (ABR). Neonates with bilateral fail OAE but normal ABR results (false-positive OAE) were considered as the case group. All recorded data were analyzed to assess the possible correlations between maternal/neonatal factors and the false-positive OAE results.

Results

One hundred and eighty-one neonates entered the study. Of all included neonates, 87 (48.1%) cases showed bilateral fail OAE and 94 (51.9%) subjects passed the OAE test. Normal ABR results (false-positive OAE) were observed in all cases with bilateral fail OAE. Comparisons of variables affecting the OAE results showed that of all perinatal factors, neonate’s sex (p = 0.046) and cesarean section (p = 0.003) were the only influencing factors that increased the risk of false-positive OAE results.

Conclusion

Based on the results, the cesarean section delivery and neonate’s male sex increased the risk of false-positive results related to OAE test. Implementing other screening tests such as ABR or Automated ABR as the initial screening test could be suggested for such cases.
The impact of celebrity influence and national media coverage on users of an alcohol reduction app: a natural experiment
Authors: Garnett Claire , Perski Olga , Beard Emma , Michie Susan , West Robert , Brown Jamie
Published: January 2021

Background

Smartphone apps are increasingly used for health-related behaviour change and people discover apps through different sources. However, it is unclear whether users differ by mode of app discovery. Drink Less is an alcohol reduction app that received national media coverage in the UK caused by celebrity influence (a male TV and radio national broadcaster, aged 51). Our aim was to compare users who discovered the app before and after this coverage.

Methods

A natural experiment assessing the impact of media coverage of Drink Less on users’ socio-demographic and drinking characteristics, app engagement levels, and extent of alcohol reduction. The study period was from 17th May 2017 to 23rd January 2019, with media coverage starting on 21st August 2018. Users were 18 years or over, based in the UK and interested in drinking less. Interrupted time series analyses using Generalised Additive Mixed Models were conducted for each outcome variable aggregated at the weekly level.

Results

In 66 weeks prior to the media coverage, 8617 users downloaded the app and 18,959 in 23 weeks afterwards. There was a significant step-level increase in users’ mean age (B = 8.17, p < .001) and a decrease in the percentage of female users (B = -27.71, p < .001), though these effects dissipated non-linearly over time. No effect of media coverage was detected on employment type or on the percentage of at-risk drinkers, though the mean Alcohol Use Disorders Identification Test score was lower after the media coverage (B = -1.43, p = .031). There was a step-level increase in app engagement – number of sessions (B = 3.45, p = .038) and number of days used (B = 2.30, p = .005) – which continued to increase over time following quadratic trends.

Conclusions

Celebrity influence leading to national media coverage in the UK of the Drink Less app was associated with more people downloading the app who were male, older and engaged with the app; and did not appear to impact employment inequality.

Authors: Laksono Agung Dwi , Wulandari Ratna Dwi , Ibad Mursyidul , Kusrini Ina
Published: January 2021

Background

Even though the Indonesian government have set regulations for maintaining exclusive breastfeeding practices, the coverage remains low. The study aims to analyze the effects of mother’s education level on the coverage of exclusive breastfeeding in Indonesia.

Methods

This study used data from the 2017 Nutrition Status Monitoring Survey. It covered data of 53,528 children under 5 years old (7–59 months) as the samples. Variables included exclusive breastfeeding status, mother’s education level, mother’s age, marital status, employment status, gender, residence, under five’s age and gender. A binary logistics regression was performed in the final test.

Results

Mothers who graduated from elementary school were 1.167 times more likely to perform exclusive breastfeeding compared to mothers who never attended schools. Additionally, those who graduated from junior high school had 1.203 times possibilities to give exclusive breastfeeding compared to mothers without educational records. While, mothers who graduated from high school were 1.177 times more likely to perform exclusive breastfeeding compared to those without educational records. Mothers who graduated from tertiary education had 1.203 times more possibilities to perform exclusive breastfeeding compared to mothers who were never enrolled to schools. Other variables also became affecting predictors on exclusive breastfeeding, such as mother’s age, mother’s employment status, child’s age, and residence.

Conclusions

The mother’s education level positively affects exclusive breastfeeding practice in Indonesia.
Gender difference of geographic distribution of the stroke incidence affected by socioeconomic, clinical and urban-rural factors: an ecological study based on data from the Brest stroke registry in France
Authors: Padilla Cindy M. , Foucault Anais , Grimaud Olivier , Nowak Emmanuel , Timsit Serge
Published: January 2021

Background

Mapping the spatial distribution of disease occurrence is a strategy to identify contextual factors that could be useful for public health policies. The purpose of this ecological study was to examine to which extent the socioeconomic deprivation and the urbanization level can explain gender difference of geographic distribution in stroke incidence in Pays de Brest, France between 2008 and 2013.

Methods

Stroke cases aged 60 years or more were extracted from the Brest stroke registry and combined at the census block level. Contextual socioeconomic, demographic, and geographic variables at the census block level come from the 2013 national census. We used spatial and non-spatial regression models to study the geographic correlation between socioeconomic deprivation, degree or urbanization and stroke incidence. We generated maps using spatial geographically weighted models, after longitude and latitude smoothing and adjustment for covariates.

Results

Stroke incidence was comparable in women and men (6.26 ± 3.5 vs 6.91 ± 3.3 per 1000 inhabitants-year, respectively). Results showed different patterns of the distribution of stroke risk and its association with deprivation or urbanisation across gender. For women, stroke incidence was spatially homogeneous over the entire study area, but was associated with deprivation level in urban census blocks: age adjusted risk ratio of high versus low deprivation = 1.24, [95%CI 1.04–1.46]. For men, three geographic clusters were identified. One located in the northern rural and deprived census blocks with a 9–14% increase in the risk of stroke. Two others clusters located in the south-eastern (mostly urban part) and south-western (suburban and rural part) with low deprivation level and associated with higher risk of stroke incidence between (3 and 8%) and (8.5 and 19%) respectively. There were no differences in profile of cardiovascular risk factors, stroke type and stroke severity between clusters, or when comparing clusters cases to the rest of the study population.

Conclusions

Understanding whether and how neighborhood and patient’s characteristics influence stroke risk may be useful for both epidemiological research and healthcare service planning.
Prevalence and risk factors of self-reported wrist and hand symptoms and clinically confirmed carpal tunnel syndrome among office workers in China: a cross-sectional study
Authors: Feng Beibei , Chen Kedi , Zhu Xiaoxia , Ip Wing-Yuk , Andersen Lars L. , Page Phil , Wang Yuling
Published: January 2021

Background

Carpal tunnel syndrome (CTS) is a common cause of pain, numbness and tingling in the wrist and hand region and is associated with repetitive wrist and hand use in office workers. However, scarce knowledge exists about the epidemiology of clinically confirmed CTS among Chinese office workers. This study aimed to investigate the prevalence of wrist/hand symptoms and CTS in office workers in China and to identify associated risk factors.

Methods

A cross-sectional survey was carried out in a metropolitan city in China involving 969 respondents (aged 17–49 years) from 30 workplaces. A questionnaire was distributed to each participant to collect their demographic, work-related physical and psychosocial factors, and wrist and hand symptoms. The wrist and hand pain/numbness symptoms were marked on a body chart and the nature and intensity of symptoms, nocturnal symptoms, as well as aggravating activities were also recorded. Clinically confirmed CTS cases were screened based on the history, Phalen’s test, Tinel Sign and skin sensation testing among symptomatic respondents. Logistic regression was employed to estimate the odds ratio (OR) and 95% confidence interval (95% CI) for the occurrence of self-reported wrist and hand symptoms and clinically confirmed CTS.

Results

The clinically confirmed CTS prevalence was 9.6%. The prevalence of wrist and hand symptoms were 22 and 15%, respectively. Frequently working in pain was associated with higher odds of CTS. Multivariate modelling adjusted for age and gender showed that prolonged computer use time and working without breaks were associated with presence of wrist/hand symptoms (adjusted ORs: 1.11 (95% CI 1.02–1.22) and 1.88 (95% CI 1.12–3.14)). Educational level was inversely associated with CTS and smoking was associated with wrist/hand complaints (adjusted OR: 2.20 (95% CI 1.19–4.07)).

Conclusions

The prevalence of work-related clinically confirmed CTS symptoms among young office workers in China is high. Frequently working in pain is closely associated with clinically confirmed CTS. Intense computer use and no breaks at work are associated with wrist and hand symptoms.
Low arterial oxygen partial pressure induces pulmonary thrombocytopenia in patients and a mouse model
Authors: Wu Limeng , Guo Ninghong , Xu Zhenyan , Wang Wei , Xiong Qinmei , Hu Jinzhu , Wan Rong , Hong Kui
Published: January 2021

Background

Recent basic studies demonstrate that the lung is a primary organ of platelet biogenesis. However, whether the pathophysiological state of the lung affect the platelets is little known. We aim to investigate the incidence of thrombocytopenia in patients with pulmonary infection (PIN) and risk factors associated with pulmonary thrombocytopenia.

Methods

In total, 11,941 patients with pulmonary infection (PIN) were enrolled, and patients with other three infectious diseases were collected as controls. The incidence of thrombocytopenia was compared, and the risk factors associated with thrombocytopenia in PIN patients were investigated by multivariate analysis. To explore the mechanism of thrombocytopenia, hypoxic model was constructed. Blood platelet counts from the angular vein (PLTs), left ventricle (PLTpost) and right ventricle (PLTpre) were determined. Megakaryocytes identified by anti-CD41 antibody were detected through flow cytometry and immunofluorescence.

Results

The incidence of thrombocytopenia in PIN was higher than that in other three infectious diseases (9.8% vs. 6.4% ~ 5.0%, P < 0.001). Low arterial oxygen partial pressure (PaO2) was an important risk factor for thrombocytopenia (OR = 0.88; P < 0.001). In a hypoxic mouse model, PLTs decreased (518.38 ± 127.92 vs 840.75 ± 77.30, P < 0.05), which showed that low PaO2 induced thrombocytopenia. The difference between the PLTpost and PLTpre (∆PLTpost-pre), representing the production of platelets in the lungs, was significantly attenuated in hypoxic mice when compared with normoxic mice (F = 25.47, P < 0.05). Additionally, proportions of CD41-positive megakaryocytes in the lungs, marrow, spleen all decreased in hypoxic mice.

Conclusion

There is a high incidence for thrombocytopenia in PIN patients. Low PaO2-induced thrombocytopenia is associated with impaired generation of platelet in the lungs.
Anti-synthetase syndrome: a rare and challenging diagnosis for bilateral ground-glass opacities—a case report with literature review
Authors: Alfraji Nasam , Mazahir Usman , Chaudhri Moiuz , Miskoff Jeffrey
Published: January 2021

Background

Anti-synthetase syndrome (ASS) is an uncommon immune-mediated entity characterized by myositis, interstitial lung disease (ILD), non-erosive arthritis, and less common features such as fever, Raynaud’s phenomenon, and skin changes in association with anti-aminoacyl-transfer-RNA antibodies, most commonly anti-Jo-1 antibodies.

Case presentation

We present a challenging and rare case of ASS-associated ILD presenting with unexplained respiratory symptoms and bilateral infiltrates on chest imaging during the COVID-19 pandemic. High clinical suspicion for ASS with early appropriate therapy with corticosteroids and immunosuppressive agents led to marked clinical improvement.

Conclusion

High index of suspicion for ASS is mandated in patients with unexplained ILD. A comprehensive autoimmune work-up is important as an early treatment with corticosteroids with or without immunomodulators improves patient outcomes and survival in an otherwise poor prognostic disease.
Modular tapered conical revision stem in hip revision surgery: mid- term results
Authors: Perticarini Loris , Rossi Stefano Marco Paolo , Fioruzzi Alberto , Jannelli Eugenio , Mosconi Mario , Benazzo Francesco
Published: January 2021

Background

The aim of this paper is to evaluate the clinical and radiological outcomes of a fluted tapered modular distal-fixation stem at medium to long-term follow-up. The hypothesis of this investigation was to verify if the use of this implant design may have provided potential advantages in femoral revisions and post-traumatic instances where the restoration of the anatomy was the prime concern.

Methods

We retrospectively reviewed 62 cases of femoral revision surgeries, performed in Paprosky type IIIA and IIIB bone defects between January 2001 and December 2011 with a mean follow-up of 8.5 ± 1.5 years (range 5.1–15.9 years) where a modular fluted stem was used. The clinical assessment was performed with the Harris Hip Score (HHS), and the radiographic evaluation was carried in order to assess the stability of the femoral component. Intra-operative and postoperative complications were recorded, and the rates of complications and revisions for any cause were determined.

Results

Mean HHS improved 35.4 points from the preoperative assessment. Radiographic evaluation showed a stable stem anchorage in 90.3% of the cases at the last follow-up. Five (8%) implants required additional surgery. Neither breakage of the stem nor loosening of the taper junction were recorded. Kaplan-Meier survivorship was 89.4% (CI: 88.8–90%) for any complication and 92.3% (CI: 91.8–92.7%) according to revision for any causes at 81 months follow-up.

Conclusions

Our findings suggest that this stem design is a reliable option in cases of complex femoral bone defects, as well as in cases with high functional deficiencies, with promising survivorship.
Fibrosarcoma of the corpus cavernosum: case report and literature review
Authors: Liu Ziwei , Zou Wenda
Published: January 2021

Background

Fibrosarcoma is a very rare tumor that arises from fibrous tissue. Less than 5% of fibrosarcoma originate from the urogenital tract. Penile fibrosarcoma, even more rare, is characterized by pain, enlargement, penile erection and urinary tract obstruction. To our knowledge, this is the second reported case named “fibrosarcoma of the corpus cavernosum”.

Case presentation

A 51-year-old male presented with a 1-month history of penis pain during erection. CT scan showed a soft tissue mass arising from the proximal part of the penis. We diagnosed it as penile sarcoma, performing local excision. The postoperative pathological result was moderately differentiated fibrosarcoma. 3 months later, CT scan showed the recurrence of the tumor, and multiple metastases. Although he received chemotherapy, he died 10 months after surgery.

Conclusions

Fibrosarcoma of the corpus cavernosum is rare and have poor prognosis. Total penile amputation may be the best treatment. The effects of chemotherapy are limited. No more effective treatment has been found for a disseminated disease to date.

Published: January 2021

Background

A diagnostic sign on magnetic resonance imaging, suggestive of posterior extrauterine adhesion (PEUA), was identified in patients with placenta previa. However, the clinical features or surgical outcomes of patients with placenta previa and PEUA are unclear. Our study aimed to investigate the clinical characteristics of placenta previa with PEUA and determine whether an altered management strategy improved surgical outcomes.

Methods

This single institution retrospective study examined patients with placenta previa who underwent cesarean delivery between 2014 and 2019. In June 2017, we recognized that PEUA was associated with increased intraoperative bleeding; thus, we altered the management of patients with placenta previa and PEUA. To assess the relationship between changes in practice and surgical outcomes, a quasi-experimental method was used to examine the difference-in-difference before (pre group) and after (post group) the changes. Surgical management was modified as follows: (i) minimization of uterine exteriorization and adhesion detachment during cesarean delivery and (ii) use of Nelaton catheters for guiding cervical passage during Bakri balloon insertion. To account for patient characteristics, propensity score matching and multivariate regression analyses were performed.

Results

The study cohort (n = 141) comprised of 24 patients with placenta previa and PEUA (PEUA group) and 117 non-PEUA patients (control group). The PEUA patients were further categorized into the pre (n = 12) and post groups (n = 12) based on the changes in surgical management. Total placenta previa and posterior placentas were more likely in the PEUA group than in the control group (66.7% versus 42.7% [P = 0.04] and 95.8% versus 63.2% [P < 0.01], respectively). After propensity score matching (n = 72), intraoperative blood loss was significantly higher in the PEUA group (n = 24) than in the control group (n = 48) (1515 mL versus 870 mL, P < 0.01). Multivariate regression analysis revealed that PEUA was a significant risk factor for intraoperative bleeding before changes were implemented in practice (t = 2.46, P = 0.02). Intraoperative blood loss in the post group was successfully reduced, as opposed to in the pre group (1180 mL versus 1827 mL, P = 0.04).

Conclusions

PEUA was associated with total placenta previa, posterior placenta, and increased intraoperative bleeding in patients with placenta previa. Our altered management could reduce the intraoperative blood loss.

Published: January 2021

Background

The treatment of hepatic injury can be complex. Medical clinical centers are often the first line hospitals for the diagnosis and treatment of hepatic trauma in China. The aim of the study is to summarize the experience in the diagnosis and treatment of hepatic trauma in one medical clinical center in China.

Methods

This retrospective study included patients with hepatic trauma admitted between January 2002 and December 2019 at the Xishan People’s Hospital of Wuxi. The outcomes were cure rate and death within 14 days post-discharge.

Results

Among the 318 patients with hepatic trauma, 146 patients underwent surgical treatment, and 172 received conservative treatment; three patients were transferred to other hospitals for further treatment; 283 patients were cured, and 35 died. Severe hepatic trauma occurred in 74 patients, with a mortality rate of 31.1% and accounting for 65.7% of total mortality. American Association for the Surgery of Trauma (AAST) grading ≥ III (OR = 3.51, 95%CI: 1.32–9.37, P = 0.012) and multiple organ injury (OR = 7.51, 95%CI: 2.51–22.46, P < 0.001) were independently associated with death. Among patients with AAST grading ≥ III, surgery was an independent protective factor for death (OR = 0.08, 95%CI: 0.01–0.45, P = 0.004). Among patients with ASST ≥ III and who underwent surgery, age (OR = 5.29, 95%CI: 1.37–20.33, P = 0.015) and peri-hepatic packing (PHP) (OR = 5.54, 95%CI: 1.43–21.487, P = 0.013) were independently associated with death.

Conclusions

AAST grading ≥ III and multiple organ injury were independently associated with death. Among patients with AAST grading ≥ III, surgery was an independent protective factor for death. Among patients with ASST ≥ III and who underwent surgery, age and PHP were independently associated with death.
Osteochondroma of the pubic symphysis causing hematuria: a case report and literature review
Authors: Song Li-cheng , Xu Qian , Li Hui , Li Zhi-jun , Li Ya , Qin Ya-fei , Wang Bao-long , Zhang Hua-feng
Published: January 2021

Background

Osteochondroma is the most common benign bone neoplasm and is sometimes referred to as osteocartilaginous exostosis. The symptoms caused by osteochondroma are rare, especially the urogenital complications. Therefore, this tumour is sometimes misdiagnosed.

Case presentation

This report described a 70-year-old woman with hematuria who was initially misdiagnosed with a bladder tumour in the outpatient department by a urologist. However, during cystoscopy, we found that the mass did not resemble a bladder tumor. Multidisciplinary approach with careful analysis of the imaging data suggested the diagnosis of osteochondroma. Open surgical excision of the mass was done and histology confirmed the diagnosis of benign osteochondroma. After 6 months of follow-up, the patient was still asymptomatic.

Conclusions

This case illustrates that hematuria is caused by not only urogenital disease but also osteochondroma. We present this case to draw the attention of clinicians to osteochondroma of the pubic symphysis.
Patient participation and associated factors in the discussions on do-not-attempt-resuscitation and end-of-life disclosure: a retrospective chart review study
Authors: Abe Akiko , Kobayashi Masato , Kohno Takashi , Takeuchi Mari , Hashiguchi Saori , Mimura Masaru , Fujisawa Daisuke
Published: January 2021

Background

Patient participation is a key foundation of advance care planning (ACP). However, a patient himself/herself may be left out from sensitive conversations such as end-of-life (EOL) care discussions. The objectives of this study were to investigate patients’ participation rate in the discussion of Cardiopulmonary Resuscitation (CPR) / Do-Not-Attempt-Resuscitation (DNAR) order, and in the discussion that the patient is at his/her EOL stage (EOL disclosure), and to explore their associated factors.

Methods

This is a retrospective chart review study. The participants were all the patients who were hospitalized and died in a university-affiliated teaching hospital (tertiary medical facility) in central Tokyo, Japan during the period from April 2018 to March 2019. The following patients were excluded: (1) cardiopulmonary arrest on arrival; (2) stillbirth; (3) under 18 years old at the time of death; and (4) refusal by their bereaved family. Presence or absence of CPR/DNAR discussion and EOL disclosure, patients’ involvement in those discussions, and their associated factors were investigated.

Results

CPR/DNAR discussions were observed in 336 out of the 358 patients (93.9%). However, 224 of these discussions were carried out without a patient (patient participation rate 33.3%). Male gender (odds ratio (OR) = 2.37 [95% confidence interval (CI) 1.32–4.25]), living alone (OR = 2.51 [1.34–4.71]), and 1 year or more from the date of diagnosis (OR = 1.78 [1.03–3.10]) were associated with higher patient’s participation in CPR/DNAR discussions. The EOL disclosure was observed in 341 out of the 358 patients (95.3%). However, 170 of the discussions were carried out without the patient (patient participation rate 50.1%). Patients who died of cancer (OR = 2.41[1.45–4.03]) and patients without mental illness (OR=2.41 [1.11–5.25]) were more likely to participate in EOL disclosure.

Conclusions

In this clinical sample, only up to half of the patients participated in CPR/DNAR discussions and EOL disclosure. Female, living with family, a shorter period from the diagnosis, non-cancer, and mental illness presence are risk factors for lack of patients’ participation in CPR/DNAR or EOL discussions. Further attempts to facilitate patients’ participation, based on their preference, are warranted.
Multilevel analysis of the role of women’s empowerment on use of contraceptive methods among married Cambodian women: evidence from demographic health surveys between 2005 and 2014
Authors: Nkoka Owen , Lee Daphne , Chuang Kun-Yang , Chuang Ying-Chih
Published: January 2021

Background

The use of contraceptives is an essential public health concept that improves overall safe motherhood and infant health. Women empowerment has been reported to influence health behaviors in women. With recent efforts to increase access to contraceptive methods, uptake of the same remains a challenge in Cambodia. There are limited studies that have examined the role of women’s empowerment at both individual- and community- level on contraceptive use in Cambodia. This study examined the individual- and community-level factors associated with contraceptive use among Cambodian married women between 2005 and 2014.

Methods

Data from 2005, 2010, and 2014 Cambodia Demographic and Health Surveys were used to analyze 2211; 10,505; and 10,849 women, respectively. Multilevel binary and multinomial logistic regression models were applied to assess the association between individual- and community- level factors, and the use of contraceptive methods.

Results

The prevalence of using modern contraceptive methods increased over time (i.e., 29.0, 38.1, and 42.3% in 2005, 2010, and 2014, respectively). At the individual level, women who attained secondary and higher education were more likely to use any contraceptives [adjusted odds ratio (aOR) = 1.43, 95% confidence interval (CI) = 1.22–1.68, and aOR = 1.23, 95% CI = 1.05–1.44 in 2010 and 2014, respectively] compared with those with no formal education. Similarly, having a high workforce participation level was significantly associated with increased likelihood of using any contraceptive methods [aOR = 1.12, 95% CI = 1.00–1.26, aOR = 1.44, 95% CI = 1.29–1.60 and in 2010 and 2014, respectively]. Other factors such as age at first marriage, residence, and having a health insurance were associated with contraceptive use. The proportional change in variance showed that about 14.3% of total variations in the odds of contraceptive use across the communities were explained by both individual- and community-level factors. Moreover, the intraclass correlation showed that about 5.2% of the total variation remained unexplained even after adjustments.

Conclusion

Both individual- and community- level factors influenced contraceptive use in Cambodia. When designing programs to improve contraceptive use, contextual influences should be taken into account for the effectiveness of the programs.

Published: January 2021

Background

Substance-Related Disorders are among the most common social problems caused by using legal and illegal substances. Therefore, this study aimed at determining the quality of life (QoL) and its related factors among women with substance use disorders referring to substance abuse treatment centers in Hamadan, west of Iran.

Methods

This cross-sectional study was carried out on 120 Iranian female substance users recruited through the census sampling method in 2018. Data collection tools consisted of demographic characteristics and QoL assessment (SF-36). Data were analyzed using SPSS-16 via one-way analysis of variance (ANOVA) and chi-square tests.

Results

The mean age of the participants was 33.2 ± 12.1 years and the mean score of their total QoL was 35.35 ± 13.5. The results of multiple linear regression analysis indicated that using methamphetamine (β =  − 6.62) was the predictor of QoL in women. Moreover, there was a significant association between QoL and age (p < 0.001), educational level (p = 0.011), and age at first use (p < 0.001).

Conclusion

According to the results, the participants’ QoL was found to be at an unsatisfactory level. So, it is essential to implement educational help-seeking behavior for treatment and effectiveness educational, as well as holding mental health intervention, school-based substance abuse prevention, and harm reduction programs of substance use. This is especially important in adolescents, young, low-educated, early drug use, and methamphetamine user women, as it may increase the QoL
Human Papilloma Virus self-sampling performance in low- and middle-income countries
Authors: Kamath Mulki Ashwini , Withers Mellissa
Published: January 2021

Background

Screening for HPV has led to significant reductions in cervical cancer deaths in high-income countries. However, the same results have not been achieved in low- and middle-income countries (LMICs). HPV self-sampling is a novel approach that could improve screening rates.

Methods

This study’s objective is to summarize the recent literature on HPV self-sampling in LMICs, focusing on sensitivity/specificity, and feasibility/acceptability of self-sampling compared to traditional screening methods. We conducted a PubMed search for articles published in English within the last 10 years on self-sampling in LMICs.

Results

Fifty eligible articles from 26 countries were included, 19 of which came from sub-Saharan Africa and 18 from Latin America/Caribbean. Seven studies examined sensitivity, with five reporting rates higher than 91%. Six reported on specificity, which was also very high at 86–97.8%. Six studies examined self-sampling concordance with provider-collected sampling, with concordance rates ranging from 87 to 97.5%. A total of 38 studies examined the feasibility/acceptability of HPV self-sampling. Participation rates were very high in all studies, even when self-sampling was done at participants’ homes (over 89% participation). Overall, participants reported that HPV self-sampling was easy to perform (75–97%, 18 studies), painless (60–90%, nine studies), and preferred over provider-collected sampling (57–100%, 14 studies). Eight studies reported follow-up rates for participants who completed self-sampling; however, these rates varied widely-from 13.7 to 90%. The major benefits of self-sampling include convenience of screening from home, less embarrassment, and less travel. Improved education and awareness of self-sampling, combined with support from community health workers, could reduce perceptions of self-sampling being inferior to provider-collected sampling. Improving follow-up of abnormal results and improving linkages to treatment are also essential.

Conclusion

Our literature review highlights HPV self-sampling is a well-performing test that shows promise in terms of expanding screening efforts for the prevention of cervical cancer-related deaths in LMICs.
Effect of Shenkang on renal fibrosis and activation of renal interstitial fibroblasts through the JAK2/STAT3 pathway
Authors: Qin Tianyu , Wu You , Liu Tonghua , Wu Lili
Published: January 2021

Background

Activation of renal fibroblasts is a critical mechanism in the process of renal fibrosis. As a commonly used herbal formula, Shenkang (SK) has been found to attenuate renal fibrosis and renal parenchyma destruction. However, the effect of SK on renal fibroblast activation in unilateral ureteral obstruction (UUO) mice and its molecular mechanism remain undetermined. The present study was performed to elucidate the effect of SK on renal fibroblast activation and renal fibrosis, as well as the potential underlying mechanism, in both NRK-49F cells and UUO mice.

Methods

NRK-49F cells were stimulated with 10 ng/ml TGF-β1 for 48 h. After SK treatment, the CCK-8 method was used to evaluate cell viability. Thirty-six C57BL/6 mice were randomly divided into the sham group, UUO group, angiotensin receptor blocker (ARB) group, and SK high-, moderate- and low-dose groups. UUO was induced in mice except those in the sham group. Drugs were administered 1 day later. On the 13th day, the fractional anisotropy (FA) value was determined by MRI to evaluate the degree of renal fibrosis. After 14 days, serum indexes were assessed. Hematoxylin and eosin (HE) and Sirius red staining were used to observe pathological morphology and the degree of fibrosis of the affected kidney. Western blotting and PCR were used to assess the expression of related molecules in both cells and animals at the protein and gene levels.

Results

Our results showed that SK reduced extracellular matrix (ECM) and α-smooth muscle actin (α-SMA) expression both in vitro and in vivo and attenuated renal fibrosis and the pathological lesion degree after UUO, suppressing JAK2/STAT3 activation. Furthermore, we found that SK regulated the JAK2/STAT3 pathway regulators peroxiredoxin 5 (Prdx5) in vitro and suppressor of cytokine signaling protein 1 (SOCS1) and SOCS3 in vivo.

Conclusions

These results indicated that SK inhibited fibroblast activation by regulating the JAK2/STAT3 pathway, which may be a mechanism underlying its protective action in renal fibrosis.
An inexpensive retrospective standard setting method based on item facilities
Authors: McLachlan John C. , Robertson K. Alex , Weller Bridget , Sawdon Marina
Published: January 2021

Background

Standard setting is one of the most challenging aspects of assessment in high-stakes healthcare settings. The Angoff methodology is widely used, but poses a number of challenges, including conceptualisation of the just-passing candidate, and the time-cost of implementing the method. Cohen methodologies are inexpensive and rapid but rely on the performance of an individual candidate. A new method of standard setting, based on the entire cohort and every item, would be valuable.

Methods

We identified Borderline candidates by reviewing their performance across all assessments in an academic year. We plotted the item scores of the Borderline candidates in comparison with Facility for the whole cohort and fitted curves to the resulting distribution.

Results

It is observed that for any given Item, an equation of the form

y ≈ C. eFx

where y is the Facility of Borderline candidates on that Item, x is the observed Item Facility of the whole cohort, and C and F are constants, predicts the probable Facility for Borderline candidates over the test, in other words, the cut score for Borderline candidates. We describe ways of estimating C and F in any given circumstance, and suggest typical values arising from this particular study: that C = 12.3 and F = 0.021.

Conclusions

C and F are relatively stable, and that the equation

y = 12.3. e0.021x

can rapidly be applied to the item Facility for every item. The average value represents the cut score for the assessment as a whole. This represents a novel retrospective method based on test takers.

Compared to the Cohen method which draws on one score and one candidate, this method draws on all items and candidates in a test. We propose that it can be used to standard set a whole test, or a particular item where the predicted Angoff score is very different from the observed Facility.
Pre-clinical remote undergraduate medical education during the COVID-19 pandemic: a survey study
Authors: Shahrvini Bita , Baxter Sally L. , Coffey Charles S. , MacDonald Bridget V. , Lander Lina
Published: January 2021

Background

The Coronavirus Disease 2019 (COVID-19) pandemic has necessitated a sudden transition to remote learning in medical schools. We aimed to assess perceptions of remote learning among pre-clinical medical students and subsequently to identify pros and cons of remote learning, as well as uncover gaps to address in ongoing curricular development.

Methods

A survey was distributed to first- and second-year medical students at the University of California San Diego School of Medicine in March 2020. Frequencies of responses to structured multiple-choice questions were compared regarding impacts of remote learning on quality of instruction and ability to participate, value of various remote learning resources, living environment, and preparedness for subsequent stages of training. Responses to open-ended questions about strengths and weaknesses of the remote curriculum and overall reflections were coded for thematic content.

Results

Of 268 students enrolled, 104 responded (53.7% of first-year students and 23.9% of second-year students). Overall, students felt that remote learning had negatively affected the quality of instruction and their ability to participate. Most (64.1%) preferred the flexibility of learning material at their own pace. Only 25.5% of respondents still felt connected to the medical school or classmates, and feelings of anxiety and isolation were noted negatives of remote learning. Most second-year students (56.7%) felt their preparation for the United States Medical Licensing Examination Step 1 exam was negatively affected, and 43.3% felt unprepared to begin clerkships. In narrative responses, most students appreciated the increased flexibility of remote learning, but they also identified several deficits that still need to be addressed, including digital fatigue, decreased ability to participate, and lack of clinical skills, laboratory, and hands-on learning.

Conclusions

Videocasted lectures uploaded in advance, electronic health record and telehealth training for students, and training for teaching faculty to increase technological fluency may be considered to optimize remote learning curricula.
Competency assessment of an undergraduate program using a third-party, objective pre-post examination
Authors: Fulton Lawrence , Lieneck Cristian , Ramamonjiarivelo Zo , Kruse Clemens Scott , Brooks Matthew S.
Published: January 2021

Background

Assessing competencies or program learning outcomes in educational programs is often a leadership challenge. This case study reports medical education program’s efforts to document undergraduate competency attainment using a pre-post, third-party, objective testing service that allows for inter-university comparison, a testing service that is being adopted by some certification and accrediting bodies.

Methods

Students completed a pre-test after program acceptance and a post-test at the end of the last didactic semester (1.5 years later) just prior to their required internships. Scores and subscores were evaluated using t-tests (Holm-adjusted p-values). MANOVA models of sub-competency difference scores were also evaluated.

Results

Results indicate competency improvement for each of the 12 areas based on the n = 55 student sample, (p < .001 for all scores). These improvements were independent of ethnicity, age, gender, and grades. The average student improved by 12.85 points (95% CI of 10.52 to 15.18) with the largest improvements in strategic planning and leadership competency areas (21.30 and 18.33 percentage points, respectively).

Conclusions

The third-party pre-post has some face validity given that student performance improved after completing a related curriculum as would be expected. Congruent with earlier studies, we find that repeated testing helps document competency attainment and that a single method for assessment is insufficient. We further document limitations of this 3d-party exam.

Published: January 2021

Background

The COVID-19 pandemic disrupted the United States (US) medical education system with the necessary, yet unprecedented Association of American Medical Colleges (AAMC) national recommendation to pause all student clinical rotations with in-person patient care. This study is a quantitative analysis investigating the educational and psychological effects of the pandemic on US medical students and their reactions to the AAMC recommendation in order to inform medical education policy.

Methods

The authors sent a cross-sectional survey via email to medical students in their clinical training years at six medical schools during the initial peak phase of the COVID-19 pandemic. Survey questions aimed to evaluate students’ perceptions of COVID-19’s impact on medical education; ethical obligations during a pandemic; infection risk; anxiety and burnout; willingness and needed preparations to return to clinical rotations.

Results

Seven hundred forty-one (29.5%) students responded. Nearly all students (93.7%) were not involved in clinical rotations with in-person patient contact at the time the study was conducted. Reactions to being removed were mixed, with 75.8% feeling this was appropriate, 34.7% guilty, 33.5% disappointed, and 27.0% relieved.

Most students (74.7%) agreed the pandemic had significantly disrupted their medical education, and believed they should continue with normal clinical rotations during this pandemic (61.3%). When asked if they would accept the risk of infection with COVID-19 if they returned to the clinical setting, 83.4% agreed.

Students reported the pandemic had moderate effects on their stress and anxiety levels with 84.1% of respondents feeling at least somewhat anxious. Adequate personal protective equipment (PPE) (53.5%) was the most important factor to feel safe returning to clinical rotations, followed by adequate testing for infection (19.3%) and antibody testing (16.2%).

Conclusions

The COVID-19 pandemic disrupted the education of US medical students in their clinical training years. The majority of students wanted to return to clinical rotations and were willing to accept the risk of COVID-19 infection. Students were most concerned with having enough PPE if allowed to return to clinical activities.
