Authors: Pan Dikang , Guo Julong , Su Zhixiang , Meng Wenzhuo , Wang Jingyu , Guo Jianming , Gu Yongquan
Published: March 2024

Background

The objective of this study was to investigate the relationship between the prognostic nutritional index (PNI) and peripheral artery disease (PAD).

Methods

The present study is a cross-sectional study based on the National Health and Nutrition Survey (1999–2004). The laboratory-calculated PNI was divided into four groups based on quartiles(Q1:PNI ≤ 50.00; Q2: 50.01–53.00; Q3:53.01–56.00; Q4: > 56.00). PAD was defined as an ankle brachial pressure index (ABPI) ≤ 0.9 on the left or right. The relationship between PNI and PAD was examined using multifactor weighted logistic regression analysis, as well as subgroup analysis. Subgroup analyses were conducted based on demographic and clinical variables.

Results

A total of 5,447 individuals were included in our final analysis. The age of the participants was 59.56 ± 13.10 years, and males accounted for 52.8% (n = 2820). The prevalence of PAD was 6.7% (n = 363). After adjusting for all factors, participants with Q1 still had an increased risk of PAD, with an OR value of 1.593 and a 95% CI of 1.232–1.991. Subgroup analysis showed no significant interaction among multiple factors.

Conclusions

In summary, we report that lower PNI are associated with a higher risk of PAD in US adults. It is hoped that this discovery can provide a reference for the prevention of PAD.

Authors: Lyu Wan-Jing , Chiu Pai-Yi , Liu Chung-Hsiang , Liao Yu-Chi , Chang Hsin-Te
Published: March 2024

Background

The early detection of dementia depends on efficient methods for the assessment of cognitive capacity. Existing cognitive screening tools are ill-suited to the differentiation of cognitive status, particularly when dealing with early-stage impairment.

Methods

The study included 8,979 individuals (> 50 years) with unimpaired cognitive functions, mild cognitive impairment (MCI), or dementia. This study sought to determine optimal cutoffs values for the Cognitive Abilities Screening Instrument (CASI) aimed at differentiating between individuals with or without dementia as well as between individuals with or without mild cognitive impairment. Cox proportional hazards models were used to evaluate the value of CASI tasks in predicting conversion from MCI to all-cause dementia, dementia of Alzheimer’s type (DAT), or to vascular dementia (VaD).

Results

Our optimized cutoff scores achieved high accuracy in differentiating between individuals with or without dementia (AUC = 0.87—0.93) and moderate accuracy in differentiating between CU and MCI individuals (AUC = 0.67 – 0.74). Among individuals without cognitive impairment, scores that were at least 1.5 × the standard deviation below the mean scores on CASI memory tasks were predictive of conversion to dementia within roughly 2 years after the first assessment (all-cause dementia: hazard ratio [HR] = 2.81 – 3.53; DAT: 1.28 – 1.49; VaD: 1.58). Note that the cutoff scores derived in this study were lower than those reported in previous studies.

Conclusion

Our results in this study underline the importance of establishing optimal cutoff scores for individuals with specific demographic characteristics and establishing profiles by which to guide CASI analysis.

Authors: Olsson Jan , Nourmohammadi Sema , Honkala Emma , Johansson Anders , Hallmans Göran , Weidung Bodil , Lövheim Hugo , Elgh Fredrik
Published: March 2024

Background

Human herpesviruses are widespread among the human population. The infections often occur unnoticed, but severe disease as well as long-term sequelae are part of the symptom spectrum. The prevalence varies among subpopulations and with time. The aim of this study was to describe the seroprevalence of Immunoglobulin G against Herpes simplex 1, Herpes simplex 2, Epstein-Barr virus and Cytomegalovirus in the adult Swedish population over a time period of several decades.

Methods

Serum samples (n = 892) from biobanks, originating from 30-year-old women, 50-year-old men and 50-year-old women sampled between 1975 and 2018, were analyzed for presence of anti-herpesvirus antibodies. Linear regression analysis was used to test for a correlation between birth year and seroprevalence. Multiple linear regression analysis was used to differentiate between other factors such as age and gender.

Results

Birth year correlated negatively with the prevalence of immunoglobulin G against Herpes simplex 1 and Epstein-Barr virus (p = 0.004 and 0.033), and positively with Immunoglobulin G against Cytomegalovirus (p = 0.039). When participant categories were analyzed separately, birth year correlated negatively with the prevalence of Immunoglobulin G against Herpes simplex 1 and Herpes simplex 2 (p = 0.032 and 0.028) in 30-year-old women, and with the prevalence of Immunoglobulin G against Cytomegalovirus in 50-year-old men (p = 0.011).

Conclusions

The prevalence of Immunoglobulin G against Herpes simplex 1, Herpes simplex 2 and Epstein-Barr virus decreases in later birth cohorts. This indicates a trend of declining risk of getting infected with these viruses as a child and adolescent.

Published: March 2024

Background

The purpose of this study was to explore the separate and combined associations of obstructive sleep apnea (OSA) risk and sleep duration with ideal cardiovascular health metrics in hemodialysis (HD) patients.

Methods

470 HD participants (average: 59.48 ± 12.89 y, 281 men) were included in this study. Sleep duration was measured as self-reported average sleep time during the previous month. The OSA risk was assessed using the STOP-BANG questionnaire. Participants were divided into three groups based on the number of ideal cardiovascular health (CVH) metrics: 0–2,3–4, and 5–7. Ordinal logistic regression was conducted to model the associations of CVH metrics with sleep duration, OSA risk, and their combined effects by adjusting for specific covariates.

Results

After adjusting for covariates, short sleep duration (< 7 h) (OR = 0.53; 95% CI [ 0.30, 0.92]) and OSA risk (OR = 0.58; 95% CI [0.32, 0.83]) were negatively associated with better CVH (ideal vs. intermediate; intermediate vs. poor), respectively. For HD patients with both short sleep duration and OSA risk, the odds of ideal CVH metrics were reduced by 72% (odds ratio 0.28 [95% CI 0.13, 0.60]).

Conclusions

Short sleep duration and OSA risk are separately and jointly associated with poor CVH in hemodialysis patients. Suitable interventions for sleep may minimize the risk of developing cardiovascular disease.

Authors: Zhou Qiao , Eggert Thomas , Zhelyazkova Ana , Choukér Alexander , Adorjan Kristina , Straube Andreas
Published: March 2024

Background

The adverse events (AEs) after a Coronavirus disease 2019 (Covid-19) Pfizer-Biotech mRNA vaccination present a medical and epidemiological issue of increasing interest. Headache is the most frequent neurological adverse effect and generally the third most common adverse event after a Covid-19 vaccination, but only a few studies focus on the link between headache and other AEs after vaccination. This study aims to investigate the correlation between headaches and Covid-19 vaccination, as well as the possible links between headaches and other AEs after Covid-19 vaccination, thereby helping the management of AEs and avoiding further occurrences.

Methods

This study is based on a published questionnaire survey of 1,402 healthcare workers. Our study focused on the 5 questions including 12 AEs and headaches extracted from the questionnaire post the first and second Covid-19 vaccination. The severity of the 12 AEs and headaches could be classified by the participants on a five-step scale: “Not at all”, “Little”, “Average”, “Quite”, and “Very” (abbreviated as “N”, “L”, “A”, “Q”, “V”). We used the Bowker test to study the comparison of headache severity, indicated on a 5-point Likert scale between the first and second vaccinations. We applied an ordinal logistic regression to the 5 categories with headache severity serving as the dependent variable and the ratings of the other 12 AEs serving as the independent variable to further explore to what extent the severity of the 12 AEs is associated with the severity of headaches. Receiver Operating Characteristic (ROC) analysis was conducted to evaluate the predictive value of the ratings of the 12 AEs to headache severity.

Results

We found that participants rated their headaches as more severe after the second vaccination, and participants who reported experiencing fatigue, flu-like symptoms, pain at the injection site, known tension-type headache, fever, dizziness/balance problems and known migraine are associated with headache symptoms.

Conclusions

There are clusters of headache-associated AEs post Covid-19 vaccination. The association of various AEs with headaches may be due to similar causative mechanisms.

Authors: Siranart Noppachai , Nakaphan Pannathorn , Viarasilpa Vasinee , Anukoolwittaya Prakit , Hemachudha Pasin
Published: March 2024

Background

Osmotic demyelinating syndrome, commonly recognized as a consequence of the rapid correction of hyponatremia, has been known to cause motor, neuropsychiatric, or extrapyramidal symptoms. We reported a patient with an unusual presentation involving bilateral hand weakness, and pseudobulbar affect. The imaging was compatible with osmotic demyelinating syndrome with bilateral hand knob lesions, despite no history of overcorrection of hyponatremia.

Case presentation

A 44-year-old female presented with three weeks of emotional lability, spastic dysarthria, and bilateral hand weakness following ankle surgery and a mild head injury. Physical examination revealed weakness in the intrinsic hand muscles, leading to a claw-like deformity of the hands, although sensation remained unimpaired. Magnetic resonance imaging (MRI) of the brain revealed several hyperintensities on fluid-attenuated inversion recovery imaging involving various areas, including the hand knob area of the bilateral precentral gyri, caudate, lentiform nuclei, and pons, suggestive of osmotic demyelinating syndrome. Clinical improvement was observed following a trial of intravenous pulse methylprednisolone and plasmapheresis.

Conclusions

Bilateral hand weakness is an unusual manifestation of osmotic demyelinating syndrome. The precentral gyrus, specifically in the hand knob area, is the vulnerable region that can result from osmotic demyelinating syndrome.
Perception of harm is strongly associated with complete ban on in-home cannabis smoking: a cross-sectional study
Authors: Tripathi Osika , Parada Humberto , Shi Yuyan , Matt Georg E. , Quintana Penelope J. E. , Liles Sandy , Bellettiere John
Published: March 2024

Background

Perception of health risk can influence household rules, but little is known about how the perception of harm from cannabis secondhand smoke (cSHS) is related to having a complete ban on in-home cannabis smoking. We examined this association among a nationally representative sample of United States adults.

Methods

Respondents were 21,381 adults from the cross-sectional Marijuana Use and Environmental Survey recruited from December 2019-February 2020. Perceived harm of cSHS exposure (extremely harmful, somewhat harmful, mostly safe, or totally safe) and complete ban of cannabis smoking anywhere in the home (yes or no) were self-reported. Logistic regression for survey-weighted data estimated covariate-adjusted odds ratios (OR) and 95% confidence intervals (CI) for the association between perceived harm of cSHS and complete ban on in-home cannabis smoking. Stratified subgroup analyses (by cannabis smoking status, cannabis use legalization in state of residence, and children under age 6 living in the home) were conducted to quantify effect measure modification of the association between perception of harm and complete ban.

Results

A complete ban on in-home cannabis smoking was reported by 71.8% of respondents. Eight percent reported cSHS as “totally safe”; 20.5% “mostly safe”; 38.3% “somewhat harmful”; and 33.0% “extremely harmful”. Those who reported cSHS as “extremely harmful” had 6 times the odds of a complete ban on in-home cannabis smoking (OR = 6.0, 95%CI = 4.9–7.2) as those reporting smoking as “totally safe”. The odds of a complete ban were higher among those reporting cSHS as “somewhat harmful” (OR = 2.6, 95%CI = 2.2–3.1) or “mostly safe” (OR = 1.4, 95%CI = 1.2–1.7) vs those reporting cSHS as “totally safe”. In each subgroup of cannabis smoking status, state cannabis use legalization, and children under the age of 6 living in the home, perceived harm was associated with a complete ban on in-home cannabis smoking.

Conclusions

Our study demonstrates perceiving cSHS as harmful is strongly associated with having a complete in-home cannabis smoking ban. With almost a third of US adults perceiving cSHS as at least “mostly safe”, there is strong need to educate the general population about potential risks associated with cSHS exposure to raise awareness and encourage adoption of household rules prohibiting indoor cannabis smoking.
Association of volatile organic compound exposure with metabolic syndrome and its components: a nationwide cross-sectional study
Authors: Dong Rui , Chang Dongchun , Shen Chao , Shen Ya , Shen Zhengkai , Tian Ting , Wang Jie
Published: March 2024

Background

Metabolic syndrome (MetS) is a health issue consisting of multiple metabolic abnormalities. The impact of exposure to volatile organic compounds (VOCs) on MetS and its components remains uncertain. This study aimed to assess the associations of individual urinary metabolites of VOC (mVOCs) and mVOC mixtures with MetS and its components among the general adult population in the United States.

Methods

A total of 5345 participants with eligible data were filtered from the 2011–2020 cycles of the National Health and Nutrition Examination Survey. Multivariate logistic regression models were applied to assess the associations of individual mVOCs with MetS and its components. The least absolute shrinkage and selection operator (LASSO) regression models were constructed to identify more relevant mVOCs. The weight quantile sum regression model was applied to further explore the links between mVOC co-exposure and MetS and its components.

Results

The results indicated positive associations between multiple mVOCs and MetS, including CEMA, DHBMA, and HMPMA. CEMA was found to be positively correlated with all components of MetS. HMPMA was associated with elevated triglyceride (TG), reduced high-density lipoprotein, and fasting blood glucose (FBG) impairment; 3HPMA was associated with an elevated risk of high TG and FBG impairment; and DHBMA had positive associations with elevated TG and high blood pressure. The co-exposure of LASSO-selected mVOCs was associated with an increased risk of elevated TG, high blood pressure, and FBG impairment.

Conclusion

Positive associations of certain individual urinary mVOCs and mVOC mixtures with MetS and its components were observed by utilizing multiple statistical models and large-scale national data. These findings may serve as the theoretical basis for future experimental and mechanistic studies and have important implications for public health.
Effects of manual therapy in addition to stretching and strengthening exercises to improve scapular range of motion, functional capacity and pain in patients with shoulder impingement syndrome: a randomized controlled trial
Authors: Tauqeer Sana , Arooj Ayesha , Shakeel Hammad
Published: March 2024

Background

The current study aimed to measure the effectiveness of manual therapy in addition to stretching and strengthening exercises in patients with shoulder impingement syndrome to improve functional capacity, pain, and scapular range of motion.

Methods

This is a single-blinded randomized controlled trial. Thirty-two participants with chronic shoulder impingement syndrome were randomly allocated into two groups. Both groups received stretching and strengthening exercises while the treatment group was given manual therapy additionally. Treatment was started after the patients signed an informed consent form. The data were collected from the University of Lahore Teaching Hospital between March 2022 and December 2022. The study aimed to measure pain using a numeric pain rating scale, functional capacity was assessed by the disability of the arm and shoulder, and goniometry was used for scapular ranges, i.e., scapular protraction and upward rotation. Each treatment session lasted 45 min for the treatment group and 30 min for the control group. The treatment comprised five days a week for four weeks, after which post-intervention measurements were taken.

Results

Thirty-two participants were enrolled in the study, and 16 were divided into each group. The mean age of the participants in the treatment group was 38.19 ± 7.31 while the comparison group was 35.69 ± 7.98. An independent sample t-test was run on the data with a 95% confidence interval, statistically significant results were obtained, i.e., p-value < 0.05, post-intervention in the treatment group. Both groups have significantly improved functional capacity and scapular protraction (p < 0.005), however, pain and scapular upward rotation were not found statistically significant in the control group (p > 0.05).

Conclusion

The addition of manual therapy along with exercise therapy showed clinical and statistical significant results for pain, functional capacity, and scapular range of motion. It demonstrated superior effects than exercise therapy alone for the chronic condition of SIS.

Trial Registration

The trial was registered in the Iranian Registry of Clinical Trials (https://www.irct.ir/) with the registration number: IRCT20230526058291N1, (Date: 12/08/2023).
Comparison of young femoral neck fractures treated by femoral neck system, multiple cancellous screws and dynamic hip screws: a retrospectively comparison study
Authors: Cai Leyi , Zheng Wenhao , Chen Chunhui , Hu Wei , Chen Hua , Wang Te
Published: March 2024

Background

Implant choice for the fixation of femoral neck fracture is one of the most important management controversies. This study aims to evaluate and compare the short-term outcomes associated with the use of the Femoral Neck System (FNS), Multiple Cancellous Screws (MCS), and Dynamic Hip Screws (DHS) in treating femoral neck fractures in a young patient population.

Methods

From June 2018 to June 2021, a total of 120 surgeries for a primary femoral neck fracture were retrospectively analyzed. This review encompassed demographic details of the patients and the mechanisms behind the injuries. Key surgical parameters such as operation duration, intraoperative blood loss, fluoroscopy duration, and hospital stay were meticulously documented. The employed surgical technique was described. All patients were followed up at 6 weeks, 3 months, 6 months, and 12 months postoperatively. Avascular necrosis of the femoral head (AVN), nonunion, malreduction, implant failure or other complications were noted. The functional status at the last follow-up was assessed using the Harris functional scoring criteria.

Results

There were 90 males and 30 females, with a mean age of 40.4 years. As to patient characteristics, there were no significant differences between the three groups. DHS group showed longer operation time(52.15 ± 4.80 min), more blood loss(59.05 ± 5.87 ml) and longer time of hospitalization(7.6 ± 0.90 d) than FNS group (39.65 ± 2.84 min, 45.33 ± 9.63 ml and 4.87 ± 0.48 d) and MCS group (39.45 ± 3.10 min, 48.15 ± 7.88 ml and 5.04 ± 0.49 d) (p < 0.05). In addition, the time of fluoroscopy in FNS group (15.45 ± 3.67) was less than that in MCS group (26.3 ± 4.76) and DHS group (27.1 ± 5.67) (p < 0.05). The cost of FNS group(44.51 ± 2.99 thousand RMB) was significantly higher than the MCS and DHS groups. The FNS, MCS and DHS groups showed a similar mean length of femoral neck shortening (LFNS) and Harris score. The FNS, MCS and DHS groups showed a similar mean rate of AVN and internal fixation failure.

Conclusions

Following successful fracture reduction, FNS, MCS, and DHS are effective for in the young femoral neck fractures. No difference was found in complications between the three groups. However, the reduced fluoroscopy time associated with FNS contributes to shorter operation durations. The adoption of minimally invasive techniques correlates with decreased blood loss and shorter hospital stays. Nevertheless, these advantages may be offset by the potential economic burden they impose.
Determining a relative total lumbar range of motion to alleviate adjacent segment degeneration after transforaminal lumbar interbody fusion: a finite element analysis
Authors: Li Ke , Cao Shuai , Chen Jing , Qin Jie , Yuan Bo , Li Jie
Published: March 2024

Background

A reduction in total lumbar range of motion (ROM) after lumbar fusion may offset the increase in intradiscal pressure (IDP) and facet joint force (FJF) caused by the abnormally increased ROM at adjacent segments. This study aimed to determine a relative total lumbar ROM rather than an ideal adjacent segment ROM to guide postoperative waist activities and further delay adjacent segment degeneration (ASD).

Methods

An intact L1-S1 finite element model was constructed and validated. Based on this, a surgical model was created to allow the simulation of L4/5 transforaminal lumbar interbody fusion (TLIF). Under the maximum total L1-S1 ROM, the ROM, IDP, and FJF of each adjacent segment between the intact and TLIF models were compared to explore the biomechanical influence of lumbar fusion on adjacent segments. Subsequently, the functional relationship between total L1-S1 ROM and IDP or total L1-S1 ROM and FJF was fitted in the TLIF model to calculate the relative total L1-S1 ROMs without an increase in IDP and FJF.

Results

Compared with those of the intact model, the ROM, IDP, and FJF of the adjacent segments in the TLIF model increased by 12.6-28.9%, 0.1-6.8%, and 0-134.2%, respectively. As the total L1-S1 ROM increased, the IDP and FJF of each adjacent segment increased by varying degrees. The relative total L1-S1 ROMs in the TLIF model were 11.03°, 12.50°, 12.14°, and 9.82° in flexion, extension, lateral bending, and axial rotation, respectively.

Conclusions

The relative total L1-S1 ROMs after TLIF were determined, which decreased by 19.6-29.3% compared to the preoperative ones. Guiding the patients to perform postoperative waist activities within these specific ROMs, an increase in the IDP and FJF of adjacent segments may be effectively offset, thereby alleviating ASD.

Published: March 2024

Purposes

Subtotal esophagectomy for esophageal cancer (EC) is associated with high morbidity rates. Tight glycemic control using an artificial pancreas (AP) is one of the promising strategies to reduce postoperative inflammation and morbidities. However, the effects of tight glycemic control using AP in patients with EC are yet to be fully elucidated.

Method

This study reviewed 96 patients with EC who underwent subtotal esophagectomy. The postoperative inflammation parameters and morbidity rates were compared between patients who used the AP (n = 27) or not (control group, n = 69). AP is a closed-loop system that comprises a continuous glucose monitor and an insulin pump.

Results

The numbers of white blood cells (WBC) and Neutrophils (Neut) were noted to be lower in the AP group than in the control group, but with no significant difference. The ratio in which the number of WBC, Neut, and CRP on each postoperative day (POD) was divided by those tested preoperatively was used to standardize the results. The ratio of WBC and Neut on 1POD was significantly lower in the AP group than in the control group. The rate of surgical site infection was lower in the AP group than in the control group.

Conclusion

AP significantly decreased WBC and Neut on 1POD; this suggests the beneficial effects of AP in alleviating postoperative inflammation.
Gasless robot-assisted transaxillary hemithyroidectomy (RATH): learning curve and complications
Authors: Xu Pengfei , Fang Qi , Mai Junhao , Zhao Zheng , Cao Fei , Wu Di , Liu Xuekui
Published: March 2024

Purpose

Gasless robot-assisted transaxillary hemithyroidectomy (RATH) is regarded as an alternative surgical option for thyroid operations. However, the associated steep learning curve is a clinical concern. This study evaluated the learning curve of RATH for surgeons without experience of endoscopic surgery and the early surgical outcomes of RATH.

Methods

We conducted a retrospective study of patients who underwent gasless RATH and conventional hemithyroidectomy (CH) at Sun Yat-sen University Cancer Center, Guangzhou, China, from June 2021 to August 2022. The learning curve and early surgical outcomes of gasless RATH were evaluated. And the early surgical outcomes of gasless RATH were compared to CH.

Results

In total, 105 patients who underwent gasless RATH and 104 patients who underwent CH were matched and assessed. The cumulative sum techniques (CUSUM) analysis showed that the peak point of gasless RATH operative time occurred at the 31st case. No clear single peak was identified in the CUSUM plot for drainage amount and blood loss. No significant difference in perioperative complications was observed between these two groups. Moreover, the number of postoperative patients who got sense of thyroid area traction were fewer in the gasless RATH group (n = 11, 10.5%) than in the CH group (n = 32, 30.8%).

Conclusion

Gasless RATH can be considered as an alternative approach to the conventional open procedure, as it is an easy remote access technique, with shorter learning curves and certain advantage such as less sense of thyroid area traction.

Accuracy of temporomandibular disorders diagnosis evaluated through the diagnostic criteria for temporomandibular disorder (DC/TDM) Axis II compared to the Axis I evaluations: a systematic review and meta-analysis
Authors: Minervini Giuseppe , Marrapodi Maria Maddalena , Siurkel Yuliia , Cicciù Marco , Ronsivalle Vincenzo
Published: March 2024

Background

The temporomandibular joint (TMJ) is a complex joint that facilitates mandibular movements during speech, chewing, and swallowing activities. The Axis I evaluation of the DC/TMD focuses on assessing physical diagnoses related to TMDs. It includes an assessment of pain and functional limitations, such as jaw opening range, joint sounds, and joint tenderness. The Axis II evaluation of the DC/TMD provides information on the patient’s psychological status and quality of life. This Systematic Review with Meta-Analysis aimed to evaluate the accuracy of Temporomandibular Disorders diagnosis considered through the Diagnostic Criteria for Temporomandibular Disorder (DC/TDM) axis II compared to the Axis I evaluations.

Methods

A search was made in PubMed, Web of Science and Lilacs for articles published from the inception until 20 January 2023. We applied the Population, Exposure, Comparator, and Outcomes (PECO) model [1] to assess document eligibility. Only studies that evaluated patients by DC/TMD Axis I and Axis II were considered. Review Manager version 5.2.8 (Cochrane Collaboration) was used for the pooled analysis. We measured the odds ratio (OR) between the two groups (Axis I and Axis II).

Results

Fifty-one articles were selected because of the search. Four papers were excluded before the screening: 2 pieces were not in English, and two were reviewed. The remaining 47 articles were selected for the title and abstract screening to evaluate whether they met the PECO criteria. Among these, four papers were established; the overall effect showed that there was no difference in TMD diagnosis between Axis I and Axis II (RR 1.17; 95% CI: 0.80– 1.71; Z:0.82; P = .41), suggesting that there is no difference between Axis I and Axis II.

Conclusion

In conclusion, DC/TMD is an effective tool for the diagnosis of TMD. It improves the accuracy of TMD diagnosis, allows for the classification of subtypes, and assesses psychosocial factors that may impact the development or maintenance of TMD symptoms.
Comparation of the effectiveness of conventional needle irrigation and photon-induced photoacoustic streaming with sodium hypochorite in the treatment of teeth with apical periodontitis: a randomized clinical trial

Published: March 2024

Photon-initiated photoacoustic streaming (PIPS) with an Er: YAG laser has been introduced in root canal treatment to improve irrigation and facilitate the removal of bacteria in the root canal system. This study aimed to compare the antibacterial effectiveness of two different root canal irrigation techniques, conventional needle irrigation (CNI) and PIPS, using 1% sodium hypochlorite (NaOCl), in the treatment of teeth with apical periodontitis. Sixty patients with a total of sixty teeth affected by apical periodontitis were included in this study. The teeth underwent root canal therapy, and after mechanical instrumentation, they were randomly assigned to two groups (n = 30) based on the final irrigation protocol: CNI or PIPS with 1% NaOCl. Bacterial suspensions in the root canals were evaluated using Adenosine 5’-triphosphate (ATP) assay kit after mechanical instrumentation and after final irrigation. Then, a follow-up was conducted after 7 days. The results revealed that final irrigation significantly reduced ATP values in both the CNI and PIPS groups (P < 0.001). The ATP values after final irrigation was greater in the CNI group compared to the PIPS group (P < 0.001). After a 7-day follow-up, percussion tenderness and fistula were significantly resolved in both groups (P < 0.05). A multivariate linear regression model was used to identify the factors that influence post irrigation ATP values. The analysis demonstrated that pre-operative percussion tenderness (P = 0.006), the presence of a fistula (P < 0.001) and the method used in the final irrigation (P < 0.001) had a significant impact on the ATP value after final irrigation. These results indicate that employing PIPS with 1% NaOCl as the final irrigation protocol exhibited superior antibacterial effectiveness and has the potential to enhance clinical outcomes in the treatment of teeth afflicted with apical periodontitis.

Published: March 2024

Objectives

To determine the efficacy of a newly developed kit in dentine sialophosphoprotein (DSPP) detection and compare it with enzyme-linked immunosorbent assay (ELISA). User acceptance was also determined.

Materials and methods

This cross-sectional study consisted of 45 subjects who were divided into 3 groups based on the severity of root resorption using radiographs: normal (RO), mild (RM), and severe (RS). DSPP in GCF samples was analyzed using both methods. Questionnaires were distributed to 30 orthodontists to evaluate future user acceptance.

Results

The sensitivity and specificity of the kit were 0.98 and 0.8 respectively. The DSPP concentrations measured using ELISA were the highest in the RS group (6.33 ± 0.85 ng/mL) followed by RM group (3.77 ± 0.36 ng/mL) and the RO group had the lowest concentration (2.23 ± 0.55 ng/mL). The new kit portrayed similar results as the ELISA, the optical density (OD) values were the highest in the RS group (0.62 ± 0.10) followed by RM group (0.33 ± 0.03) and the RO group (0.19 ± 0.06). The differences among all the groups were statistically significant (p < 0.05) for both methods. The Pearson correlation coefficient showed a statistically significant (p < 0.001) strong and positive correlation between DSPP concentrations and OD values.

Conclusions

The new kit was validated to detect the colour intensities of different severity of root resorptions. Most of the responses to the survey were positive towards the new kit for being a safer and simpler method to detect apical root resorption.
The influence of ambient environmental factors on breakthrough cancer pain: insights from remote health home monitoring and a proposed data analytic approach
Authors: Homdee Nutta , Lach John , Blackhall Leslie , LeBaron Virginia
Published: March 2024

Background

Breakthrough cancer pain (BTCP) is primarily managed at home and can stem from physical exertion and emotional distress triggers. Beyond these triggers, the impact of ambient environment on pain occurrence and intensity has not been investigated. This study explores the impact of environmental factors on the frequency and severity of breakthrough cancer pain (BTCP) in the home context from the perspective of patients with advanced cancer and their primary family caregiver.

Methods

A health monitoring system was deployed in the homes of patient and family caregiver dyads to collect self-reported pain events and contextual environmental data (light, temperature, humidity, barometric pressure, ambient noise.) Correlation analysis examined the relationship between environmental factors with: 1) individually reported pain episodes and 2) overall pain trends in a 24-hour time window. Machine learning models were developed to explore how environmental factors may predict BTCP episodes.

Results

Variability in correlation strength between environmental variables and pain reports among dyads was found. Light and noise show moderate association (r = 0.50–0.70) in 66% of total deployments. The strongest correlation for individual pain events involved barometric pressure (r = 0.90); for pain trends over 24-hours the strongest correlations involved humidity (r = 0.84) and barometric pressure (r = 0.83). Machine learning achieved 70% BTCP prediction accuracy.

Conclusion

Our study provides insights into the role of ambient environmental factors in BTCP and offers novel opportunities to inform personalized pain management strategies, remotely support patients and their caregivers in self-symptom management. This research provides preliminary evidence of the impact of ambient environmental factors on BTCP in the home setting. We utilized real-world data and correlation analysis to provide an understanding of the relationship between environmental factors and cancer pain which may be helpful to others engaged in similar work.
“Pharmacotrophy”: a playful tournament for game- and team-based learning in pharmacology education - assessing its impact on students’ performance
Authors: Delage Clément , Palayer Maeva , Lerouet Dominique , Besson Valérie C.
Published: March 2024

Background

At the Faculty of Pharmacy of Paris, we conducted a pharmacology tournament in 2021 and 2022, named “Pharmacotrophy”, to offer a game-, team- and competitive-based learning innovation based on fun and challenge. This article aims to (1) provide a detailed overview of the organisation of “Pharmacotrophy,” (2) present and compare feedback from both students and teachers, and (3) assess the impact of student participation on their exam marks.

Methods

“Pharmacotrophy” took place in 2021 and 2022 over a two-week period at the beginning of the exam revision phase. It involved a combination of remote matches using the online quiz creation tool Kahoot!® and in-person matches. Teams, consisting of three students from the 4th or 5th year, participated in several selection rounds leading up to the final match. The questions covered various topics from the pharmacology curriculum. Using an anonymous online survey, we collected the feedback from students and teacher regarding the organisation of the tournament and the interest and difficulty of the different type of questions. We retrospectively compared the exam marks of 4th year students who took part in “Pharmacotrophy” (n2021 = 19 and n2022 = 20) with those of the rest of the 4th year (n2021 = 315–320 and n2022 = 279–281), both in the year before “Pharmacotrophy” and just after the tournament.

Results

Students highlighted the educational benefits of team-based and game-based learning. This novel approach positively and constructively motivated students to review pharmacology. Additionally, students appreciated the establishment of a trust-based relationship with their teachers. All students had a similar pharmacology level based on their exam results in the year before “Pharmacotrophy.” After the tournament, participants had marks 20.1% higher in pharmacology questions compared to non-participants (p = 0.02), while they had comparable overall levels, as evidenced by their final grade averages and marks in non-pharmacology questions. Moreover, participants who advanced further in the competition achieved higher marks in pharmacology questions compared to those who were eliminated early in the tournament.

Conclusion

The implementation of “Pharmacotrophy” provided students with an enjoyable way to review pharmacology coursework and revived the interest in pharmacology for some. Specifically, participating in “Pharmacotrophy” led to an increase in pharmacology marks for students who were not among the top performers in the class or did not excel in pharmacology in the previous year. This study quantified the pedagogical value of this innovative curriculum in terms of knowledge acquisition.
Reflective capacity and context of reflections: qualitative study of second-year medical students’ learning diaries related to a general practice course
Authors: Paloniemi Elina , Hagnäs Maria , Mikkola Ilona , Timonen Markku , Vatjus Ritva
Published: March 2024

Background

Reflective capacity is a prerequisite for transformative learning. It is regarded as an essential skill in professional competence in the field of medicine. Our aim was to investigate the reflective capacity and the objects of action (themes) which revealed reflective writing of medical students during a general practice/family medicine course.

Methods

Second-year medical students were requested to write learning diaries during a compulsory course in general practice/family medicine consisting of the principles of the physician-patient relationship. The course included a group session supervised by a clinical lecturer and a 3-day training period in a local health centre. We conducted data-driven content analysis of the learning diaries. In the learning diaries, student observations were most commonly directed to events during the training period and to group sessions. Occasionally, observation was directed at inner experience.

Results

The following themes were related to reflective writing: feelings towards the end of life, demanding situations in practice, physician’s attitude to patient, student’s inner experiences, and physician’s well-being. The entries indicated different types of reflective capacity. Three subgroups were identified: ‘simple reporting,’ ‘reflective writing,’ and ‘advanced reflective writing.’

Conclusion

Professional growth requires the development of reflective capacity, as it is essential for successful patient care and better clinical outcomes. To develop and enhance the reflective capacity of medical students during their education, the curriculum should provide frequent opportunities for students to assess and reflect upon their various learning experiences.

Published: March 2024

Background

Previous studies have explored the relationships of psychological capital with employees’ job performance in the health sector. However, the possible indirect pathways, including a serial mediation of problem-focus coping and job engagement, have not been extensively examined. This article explores how psychological capital influences nurses’ coping strategies focused on problem-solving, their level of engagement with their jobs, and how this, in turn, affects their job performance.

Methods

The study involved 575 nurses from Cameroon’s public health sector. It investigated how psychological capital, an intrinsic resource, triggers nurses’ problem-focus coping liaison with job engagement to impact job performance. Analysis was conducted to assess the relationships among psychological capital, problem-focus coping, job engagement, and job performance with the use of SmartPLS 4.0 and PROCESS 4.2.

Results

Findings revealed a significant effect of psychological capital on problem-focus coping, job engagement and job performance. Moreover, notable relationships were identified between psychological capital, problem-focus coping, job engagement, and performance, highlighting a chain mediation effect.

Conclusion

The research advocates for hospital managers to employ strategies fostering employees’ psychological capital to better cope with organizational stressors to promote job engagement and enhance job performance. The study contributes fresh insights into healthcare organizational dynamics and human resource management, providing a foundation for future advancements in this field.
The effects of COVID-19 pandemic on women’s access to maternal health and family planning services in Egypt: an exploratory study in two governorates
Authors: Abdel Tawab Nahla , Tayel Salma A. , Radwan Sally M. , Ramy Mohamed A.
Published: March 2024

Background

The COVID-19 pandemic has been noted to decrease access to maternal health and family planning services globally. However, evidence from the Middle East and North Africa region is very scarce and limited. We qualitatively explored women’s experiences in accessing maternal health and family planning services during the COVID-19 lockdown months in the two Egyptian governorates of Port Said and Souhag.

Methods

Using a case study design, semi-structured phone interviews were conducted with a total of 40 women aged 18–35 years from Port Said and Souhag governorates in Egypt. Interviews explored women’s experiences in accessing maternal health and family planning services during COVID-19 lockdown months, their coping strategies, and impact of challenges and/or coping strategies on participants and their families. The collected data was analyzed manually using qualitative thematic analysis.

Results

Many participants were unable to access maternal health and family planning services during COVID-19 lockdown due to fear of contracting the virus, closure of health facilities, changing service hours, family planning method or drug stock-outs, and/or financial constraints. The above challenges in accessing services along with coping strategies that some women and their families used exposed women to additional health risks, including unintended pregnancies, and posed several social, emotional, and financial burdens to many.

Conclusions

The COVID-19 pandemic and associated lockdown measures undermined women’s access to maternal and family planning services and interfered with their ability to achieve their reproductive goals. The paper concludes with a number of recommendations to ensure access to maternal and family planning services at times of crisis. Those recommendations include: (1) adapting reliable guidelines from humanitarian settings, (2) providing adequate guidance to healthcare providers and the public to tackle fears and misinformation, (3) making self-care products available such as oral contraceptive pills, vaginal rings and self- administered injectables, (4) involving other health professionals in the provision of maternal and family planning services through task-sharing/shifting, (5) expanding the use of telemedicine and/or digital health services especially to those living in remote areas and (6) raising policymakers’ awareness of the centrality of reproductive rights and the importance of protecting them at all times.
