Published: January 2024

Background

The effect of ultra-processed foods (UPFs) on chronic kidney disease (CKD) has been studied in some studies. The present study aimed to investigate the association between UPF consumption and the risk of protein-energy wasting (PEW) and sarcopenia in patients with CKD in the Iranian population.

Methods

The current cross-sectional study included 110 patients with CKD referred to two clinics in Shiraz, Iran. The International Society of Renal Nutrition and Metabolism (ISRNM) criteria and the Asian Working Group for Sarcopenia (AWGS) guideline were considered for the diagnosis of PEW and sarcopenia, respectively. The valid semi-quantitative food frequency questionnaire was used to assess participants' dietary intake. The logistic regression was used to examine the association of UPFs with PEW and sarcopenia.

Results

We observed no significant association between sarcopenia and PEW with UPFs in the crude model. After adjusting for confounders, we observed a significantly higher odds of sarcopenia in the upper versus lower median of UPF intake (odds ratio (OR) = 3.59, 95% confidence interval (CI): 1.02–12.62, P = 0.046).

Conclusions

Our findings suggest a positive relationship between UPF intake and sarcopenia among CKD patients. Therefore, reducing the intake of UPFs may decrease the odds of sarcopenia in patients suffering from CKD.
“Systems seem to get in the way”: a qualitative study exploring experiences of accessing and receiving support among informal caregivers of people living with chronic kidney disease
Authors: Coumoundouros Chelsea , Farrand Paul , Sanderman Robbert , von Essen Louise , Woodford Joanne
Published: January 2024

Background

The well-being of informal caregivers of people living with chronic kidney disease is influenced by their experiences with support, however, few studies have focused on exploring these experiences. This study aimed to explore informal caregivers’ experiences accessing and receiving support while caring for someone living with chronic kidney disease.

Methods

Informal caregivers of people living with chronic kidney disease (n = 13) in the United Kingdom were primarily recruited via community organisations and social media adverts to participate in semi-structured interviews. Interviews explored support needs, experiences of receiving support from different groups (e.g. healthcare professionals, family/friends), and barriers and facilitators to accessing support. Support was understood as including emotional, practical, and informational support. Data were analysed using reflexive thematic analysis.

Results

Three themes were generated: (1) “Systems seem to get in the way” – challenges within support systems, illustrating the challenges informal caregivers encountered when navigating complex support systems; (2) Relying on yourself, describing how informal caregivers leveraged their existing skills and networks to access support independently, while recognising the limitations of having to rely on yourself to find support; and (3) Support systems can “take the pressure off”, showing how support systems were able to help informal caregivers cope with the challenges they experienced if certain conditions were met.

Conclusions

In response to the challenges informal caregivers experienced when seeking support, improvements are needed to better consider informal caregiver needs within healthcare systems, and to develop interventions tailored to informal caregiver needs and context. Within the healthcare system, informal caregivers may benefit from system navigation support and better integration within healthcare teams to ensure their informational support needs are met. New interventions developed to support informal caregivers should fit within their existing support systems and incorporate the qualities of support, such as empathy, that were valued. Additionally, use of an equity framework and user-centered design approaches during intervention development could help ensure interventions are accessible and acceptable.

Published: January 2024

Background

To explore the association between liver metabolism-related indicators in maternal serum and neonatal hyperbilirubinemia (NHB), and further investigate the predictive value of these indicators in NHB-related amino acid metabolism disorders.

Methods

51 NHB and 182 No-NHB newborns and their mothers who treated in the Fourth Hospital of Shijiazhuang from 2018 to 2022 were participated in the study. The differences in clinical data were compared by the Mann-Whitney U test and Chi-square test. Multivariate logistic regression was used to analyze the relationship between maternal serum indicators and the occurrence of NHB. The correlation analysis and risk factor assessment of maternal serum indicators with NHB-related amino acid metabolic disorders were performed using Spearman correlation analysis and multivariate logistic regression.

Results

Compared to the non NHB group, the NHB group had higher maternal serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), ALT/AST, and total bile acid (TBA), while lower levels of serum albumin (ALB), total cholesterol (TC) and high-density lipoprotein (HDL). The levels of alanine (ALA), valine (VAL), ornithine (ORN), and proline (PRO) in the newborns were reduced in NHB group, while arginine (ARG) showed a tendency to be elevated. Multiple logistic regression analysis showed that maternal ALT, AST, ALT/AST, and TBA levels were all at higher risk with the development of NHB, whereas ALB, TC, and HDL levels were negatively associated with NHB development. Increasing maternal TBA level was associated with lower ALA (r=-0.167, p = 0.011), VAL (r=-0.214, p = 0.001), ORN (r=-0.196, p = 0.003), and PRO in the newborns (r=-0.131, p = 0.045). Maternal ALT level was negatively associated with ALA (r=-0.135, p = 0.039), VAL (r=-0.177, p = 0.007), ORN (r=-0.257, p < 0.001), while ALT/AST was positively correlated with ARG (r = 0.133, p = 0.013). After adjustment for confounding factors, maternal serum TBA and ALT were the independent risk factor for neonatal ORN metabolic disorders [(adjusted odds ratio (AOR) = 0.379, 95%CI = 0.188–0.762, p = 0.006), (AOR = 0.441, 95%CI = 0.211–0.922, p = 0.030)]. Maternal ALT level was an independent risk factor for neonatal VAL metabolic disorders (AOR = 0.454, 95%CI = 0.218–0.949, p = 0.036).

Conclusions

The levels of high TBA, ALT, AST, and low HDL, TC of maternal were associated with the risk of NHB. Maternal TBA and ALT levels were independent risk factors for NHB-related amino acid disturbances which have value as predictive makers.

Published: January 2024

Objectives

Functional retentive overflow incontinence (retentive FI) is the most common cause of fecal soiling in children. Based on the clinical experiences, the treatment of retentive FI in patients with comorbid psychiatric disorders was accelerated when Risperidone was used as treatment for their psychiatric comorbidities; therefore, this study was conducted to evaluate the effect of risperidone in the treatment of retentive FI in children and adolescents.

Methods

In this double-blind, randomized, placebo-controlled trial, 140 patients aged 4–16 years eligible for the study were randomized into two groups, receiving either 0.25–0.5 mg of Risperidone syrup (n = 70) or maltodextrin syrup (placebo group, n = 70) every 12 h daily for 12 weeks. Sociodemographic data, including age, sex, weight, height, BMI, BMI z-score, and socioeconomic status, was recorded, and the number of nocturnal FI, diurnal FI, and painful defecations was measured.

Results

136 participants (69 on Risperidone and 67 on placebo) were included in the study. Mean age of participants in the intervention and placebo groups were 7.2 ± 2.4 years and 8.0 ± 3.1 years, respectively. The mean number of nocturnal FI (Ptrend=0.39) and diurnal FI (Ptrend=0.48) in patients without psychiatric comorbidities, and the number of painful defecations for participants with and without psychiatric comorbidities (P = 0.49, P = 0.47, respectively) were not significantly different between the groups, but a significant effect was observed in diurnal FI after Risperidone treatment in patients with psychiatric comorbidities (P < 0.001).

Conclusion

Risperidone, when used along with other non-pharmacological interventions, may be helpful in treating FI in pediatric patients with psychiatric comorbidities.
Moderating effect of alexithymia between problem gambling and psychotic experiences in university students

Published: January 2024

Background

Most of the young individuals with problem gambling (PG) or psychotic experiences (PEs) are less prone to seek medical help. Therefore, community-based studies investigating the relationship between these entities in non-clinical young people across a continuum of severity are warranted. To this end, the present study proposes to advance knowledge on the mechanisms that potentially underlie the association between PG and PEs, by examining the role of a potential moderator, i.e. alexithymia, in this relationship.

Methods

A total of 399 participants enrolled in this study (mean age = 21.58 ± 3.20 years) participated in an online cross-sectional survey. The South Oaks Gambling Screen (SOGS), the Prodromal Questionnaire-Brief (PQ-B), and the Toronto alexithymia scale (TAS-20) were used.

Results

Thirty-three (8.3%) participants had problem-gambling, whereas 13 (3.3%) were probable pathological gamblers. Moderation analysis results adjusted over confounders (age, household crowding index, marital status, personal history of mental disorder, other illegal drug use) showed that the interaction PG by alexithymia (p = .018) was significantly associated with PEs scores. At moderate (Beta = 1.93) and high (Beta = 3.38) levels of alexithymia, more PG was significantly associated with more PEs scores.

Conclusion

Findings suggest that GP may have a different impact on PEs depending on the individual’s level of alexithymia. As such, both alexithymia and gambling behavior should be considered in the clinical assessment of young people who present with PEs, which can help in implementing more tailored and individualized treatment plans.
The effectiveness of mental health interventions involving non-specialists and digital technology in low-and middle-income countries – a systematic review
Authors: Mudiyanselage Kalpani Wijekoon Wijekoon , De Santis Karina Karolina , Jörg Frederike , Saleem Maham , Stewart Roy , Zeeb Hajo , Busse Heide
Published: January 2024

Background

Combining non-specialists and digital technologies in mental health interventions could decrease the mental healthcare gap in resource scarce countries. This systematic review examined different combinations of non-specialists and digital technologies in mental health interventions and their effectiveness in reducing the mental healthcare gap in low-and middle-income countries.

Methods

Literature searches were conducted in four databases (September 2023), three trial registries (January–February 2022), and using forward and backward citation searches (May–June 2022). The review included primary studies on mental health interventions combining non-specialists and digital technologies in low-and middle-income countries. The outcomes were: (1) the mental health of intervention receivers and (2) the competencies of non-specialists to deliver mental health interventions. Data were expressed as standardised effect sizes (Cohen’s d) and narratively synthesised. Risk of bias assessment was conducted using the Cochrane risk-of-bias tools for individual and cluster randomised and non-randomised controlled trials.

Results

Of the 28 included studies (n = 32 interventions), digital technology was mainly used in non-specialist primary-delivery treatment models for common mental disorders or subthreshold symptoms. The competencies of non-specialists were improved with digital training (d ≤ 0.8 in 4/7 outcomes, n = 4 studies, 398 participants). The mental health of receivers improved through non-specialist-delivered interventions, in which digital technologies were used to support the delivery of the intervention (d > 0.8 in 24/40 outcomes, n = 11, 2469) or to supervise the non-specialists’ work (d = 0.2–0.8 in 10/17 outcomes, n = 3, 3096). Additionally, the mental health of service receivers improved through digitally delivered mental health services with non-specialist involvement (d = 0.2–0.8 in 12/27 outcomes, n = 8, 2335). However, the overall certainty of the evidence was poor.

Conclusion

Incorporating digital technologies into non-specialist mental health interventions tended to enhance non-specialists’ competencies and knowledge in intervention delivery, and had a positive influence on the severity of mental health problems, mental healthcare utilization, and psychosocial functioning outcomes of service recipients, primarily within primary-deliverer care models. More robust evidence is needed to compare the magnitude of effectiveness and identify the clinical relevance of specific digital functions. Future studies should also explore long-term and potential adverse effects and interventions targeting men and marginalised communities.
The effect of smaller classes on infection-related school absence: evidence from the Project STAR randomized controlled trial
Authors: von Hippel Paul T.
Published: January 2024

Background

In an effort to reduce viral transmission, many schools reduced class sizes during the recent pandemic. Yet the effect of class size on transmission is unknown.

Methods

We used data from Project STAR, a randomized controlled trial in which 10,816 Tennessee elementary students were assigned at random to smaller classes (13 to 17 students) or larger classes (22 to 26 students) in 1985-89. We merged Project STAR schools with data on local deaths from pneumonia and influenza in the 122 Cities Mortality Report System. Using mixed effects linear, Poisson, and negative binomial regression, we estimated the main effect of smaller classes on absence. We used an interaction to test whether the effect of small classes on absence was larger when and where community pneumonia and influenza prevalence was high.

Results

Small classes reduced absence by 0.43 days/year (95% CI -0.06 to -0.80, p < 0.05), but small classes had no significant interaction with community pneumonia and influenza mortality (95% CI -0.27 to + 0.30, p > 0.90), indicating that the reduction in absence due to small classes was not larger when community disease prevalence was high.

Conclusion

Small classes reduced absence, but the reduction was not larger when disease prevalence was high, so the reduction in absence was not necessarily achieved by reducing infection. Small classes, by themselves, may not suffice to reduce the spread of respiratory viruses.
Prevalence of mental disorders among middle-aged population of primary healthcare centers in Northeastern Iran
Authors: Talebi Mehdi , Taghipour Ali , Raouf-Rahmati Amene , Farokhani Ehsan Musa , Ghaffariyan-Jam Saeed , Samarghandi Azadeh , Nemati Maryam , Nemati Ahmad
Published: January 2024

Background

Primary healthcare centers (PHCs) serve as the cornerstone of accessible medical services in society, playing a crucial role in screening, detecting, and treating various health issues. This study aimed to investigate the prevalence of psychiatric disorders in middle-aged individuals who refer to PHCs and the potential of PHCs in diagnosing mental disorders.

Methods

This cross-sectional study was implemented at PHCs under the supervision of Mashhad University of Medical Sciences (MUMS) in northeast Iran in 2018. The enrolled subjects were middle-aged adults who had electronic medical records in SINA, an integrated health management system, and the electronic medical records of MUMS. The prevalence of psychiatric disorders by type and their relationship with demographic information was evaluated by a Chi-square test using SPSS 22.

Results

This study involved 218,341 middle-aged participants. Prevalence of psychiatric disorders was 8.59%, and depression (53.72%) and anxiety (42.02%) were the most common psychiatric disorders in both males and females. The prevalence of mental disorders was significantly higher in females than in males (88.18% vs. 18.81%; P < 0.0001). Indeed, a significant higher prevalence of depression, anxiety, somatoform, childhood psychiatric disorder, and bipolar disorders was observed in females compared to males (P < 0.05). In addition, individuals between the age of 45–60 years, and those from rural areas showed more prevalence of mental disorders than others, but these differences were not significant.

Conclusions

Considering the previous studies in Iran, the prevalence of mental disorders among patients presenting to PHCs was noticeably lower than expected rates. It seems probable that this huge difference is due to poor screening and detection of mental illness in PHCs of MUMS. It is recommended that health policymakers pursue specific measures to make PHCs more helpful for people with mental health problems in the community.

Authors: Yuan Ziyang , Zhu Xu , Dai Yike , Shi Lin , Feng Ziyang , Li Zhiyao , Diao Naicheng , Guo Ai , Yin Heyong , Ma Lifeng
Published: January 2024

Background

Rotator cuff tears (RCT) is a common musculoskeletal disorder in the shoulder which cause pain and functional disability. Diabetes mellitus (DM) is characterized by impaired ability of producing or responding to insulin and has been reported to act as a risk factor of the progression of rotator cuff tendinopathy and tear. Long non-coding RNAs (lncRNAs) are involved in the development of various diseases, but little is known about their potential roles involved in RCT of diabetic patients.

Methods

RNA-Sequencing (RNA-Seq) was used in this study to profile differentially expressed lncRNAs and mRNAs in RCT samples between 3 diabetic and 3 nondiabetic patients. Gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) pathway analysis were performed to annotate the function of the differentially expressed genes (DEGs). LncRNA-mRNA co-expression network and competing endogenous RNA (ceRNA) network were constructed to elucidate the potential molecular mechanisms of DM affecting RCT.

Results

In total, 505 lncRNAs and 388 mRNAs were detected to be differentially expressed in RCT samples between diabetic and nondiabetic patients. GO functional analysis indicated that related lncRNAs and mRNAs were involved in metabolic process, immune system process and others. KEGG pathway analysis indicated that related mRNAs were involved in ferroptosis, PI3K-Akt signaling pathway, Wnt signaling pathway, JAK-STAT signaling pathway and IL-17 signaling pathway and others. LncRNA-mRNA co-expression network was constructed, and ceRNA network showed the interaction of differentially expressed RNAs, comprising 5 lncRNAs, 2 mRNAs, and 142 miRNAs. TF regulation analysis revealed that STAT affected the progression of RCT by regulating the apoptosis pathway in diabetic patients.

Conclusions

We preliminarily dissected the differential expression profile of lncRNAs and mRNAs in torn rotator cuff tendon between diabetic and nondiabetic patients. And the bioinformatic analysis suggested some important RNAs and signaling pathways regarding inflammation and apoptosis were involved in diabetic RCT. Our findings offer a new perspective on the association between DM and progression of RCT.

Authors: Wang Enjie , Li Jun , Hong Tao , Xie Zexin , Ge Yong , Zhou Xiaotong , Zhang Hao
Published: January 2024

Background

In various surgical specialties, preoperative surgical warm-up has been demonstrated to affect a surgeon’s performance and the perioperative outcomes for patients. However, the influence of warm-up activities on video-assisted thoracoscopic surgery lobectomy (VATSL) remains largely unexplored. This study aims to investigate the potential effects of preoperative surgical warm-up on VATSL.

Methods

A cohort of 364 patients diagnosed with lung cancer through pathology and undergoing VATSL at the Thoracic Surgery Department of Xuzhou Medical University from January 2018 to September 2022 were included. Patients were categorized into two groups: the warm-up group, comprising 172 patients undergoing their first VATSL of the day, and the warm-up effect group, consisting of 192 patients undergoing their second VATSL on the same day. Propensity score matching was employed to compare operation times and postoperative complications between the two groups, resulting in 159 matched cases in each group.

Results

There were no statistically significant differences in operation time (154.5 ± 54.9 vs. 147.2 ± 54.4 min, p = 0.239) and postoperative complications (including pulmonary infection, atelectasis, long-term pulmonary air leakage requiring incision suture in the operating room, and postoperative pleural effusion) (14:22 cases, p = 0.157) between the warm-up and warm-up effect groups.

Conclusion

The findings suggest that preoperative surgical warm-up does not significantly affect the perioperative outcomes of VATSL.
Comparison of two minimally invasive surgical approaches for hypertensive intracerebral hemorrhage: a study based on postoperative intracranial pressure parameters
Authors: Lian Minxue , Li Xiaolei , Wang Yuangang , Che Hongmin , Yan Zhongnan
Published: January 2024

Background

Increased intracranial pressure (ICP) in patients with hypertensive intracerebral hemorrhage (HICH) has been associated with poor prognosis. The transsylvian insular approach (TIA) and the transcortical (TCA) approach are applied for patients with HICH. We aimed to compare the postoperative ICP parameters of TIA and TCA to identify which procedure yields better short-term outcomes in patients with basal ganglia hematoma volumes ranging from 30 to 50 mL.

Methods

Eighty patients with basal ganglia hematomas 30–50 mL were enrolled in this study. Patients were implanted with ICP probes and divided into TIA and TCA groups according to the procedure. The ICP values were continuously recorded for five days at four-hour intervals. Short-term outcomes were evaluated using the length of hospitalization and postoperative consciousness recovery time.

Results

No statistically significant differences were found in age, sex, GCS score at admission, hematoma volume, and hematoma clearance rate (p > 0.05). The results showed that postoperative initial ICP, ICP on the first postoperative day, mean ICP, DICP20 mmHg × 4 h, postoperative consciousness recovery time, the length of hospitalization, mannitol utilization rate and the mannitol dosage were lower in the TIA group than in the TCA group (p < 0.05). Postoperative consciousness recovery time was positively correlated with ICP on the first postoperative day, and the length of hospitalization was positively correlated with mean ICP.

Conclusions

TIA is more effective than TCA in improving the short-term outcomes of patients with basal ganglia hematoma volumes ranging from 30 to 50 mL according to comparisons of postoperative ICP parameters.
Reliability and validity of Oswestry Disability Index among patients undergoing lumbar spinal surgery
Authors: Koivunen Konsta , Widbom-Kolhanen Sara , Pernaa Katri , Arokoski Jari , Saltychev Mikhail
Published: January 2024

Background

The objective of this study was to explore the internal consistency and factor structure of the Oswestry Disability Index among patients undergoing spinal surgery. The sample consisted of 1,515 patients who underwent lumbar spinal surgery at a university hospital between 2018 and 2021.

Methods

The patients responded to the Oswestry Disability Index within 2 months before surgery. Cronbach’s alpha was used to assess the internal consistency. The factor structure was evaluated using exploratory and confirmatory factor analyses.

Results

The average age of 1,515 patients was 58.5 (SD 15.8) years and 53% were women. The mean ODI score was 43.4% (SD 17.4%). Of the patients, 68% underwent microsurgical excision of the lumbar intervertebral disc displacement or decompression of the lumbar nerve roots. The internal consistency of the Oswestry Disability Index was found to be good, with an alpha of 0.87 (95% CL 0.86 to 0.88). Exploratory factor analysis resulted in unidimensional structure. Item loadings on this retained factor were moderate to substantial for all 10 items. One-factor confirmatory factor analysis model demonstrated an acceptable fit. The correlations between the main factor “disability” and the individual items varied from moderate (0.44) to substantial (0.76). The highest correlations were observed for items “traveling”, “personal care”, and “social life”. The lowest correlations were observed for the item “standing”.

Conclusions

The Oswestry Disability Index is a unidimensional and internally consistent scale that can be used to assess the severity of disability in patients undergoing lumbar spinal surgery. In the studied population, “traveling,” “social life,” “sex life” and “personal care” were the most important items to define the severity of disability, while “walking” and “standing” were the least important items. The generalizability of the results might be affected by the heterogeneity and modest size of the studied cohort.

Published: January 2024

Background

Very recently, a significant relationship between tonsilloliths and dental plaque-related pathologies was reported using digital panoramic radiographs. Their dynamics over time suggest that tonsilloliths may be in a permanently active phase that functions to remove foreign matter. The aim of the study was to evaluate the relationship between the occurrence of tonsilloliths and the extent of periodontitis.

Methods

A total of 608 patients who underwent both CT and panoramic radiographs were included in the study. Both of two imaging were retrospectively and independently assessed with respect to the presence of tonsilloliths detected on CT and panoramic radiographs, and bone defects caused by periodontitis detected on panoramic radiographs. The type of retrospective study is case-control. Then, the differences between age groups were evaluated with respect to the degree of bone resorption and its correlation with the presence of tonsilloliths. The relationships between categorical variables were assessed using Pearson’s correlation coefficient or Spearman’s correlation coefficient.

Results

There was a significant relationship between tonsilloliths on CT and the extent of the bone defect on panoramic radiographs (Spearman’s correlation coefficient, r = 0.648, p = 0.043). In addition, there was a significant difference in the extent of the bone defect caused by periodontitis between subjects with and without tonsilloliths in the 60 to 69-year-old group (Mann-Whitney U test, p = 0.025), 70 to 79-year-old group (Mann-Whitney U test, p = 0.002), and 80 to 89-year-old group (Mann-Whitney U test, p = 0.022), but not in other age groups (Mann-Whitney U test: under 9-year-old group, p = 1.000; 10 to 19-year-old group, p = 1.000; 20 to 29-year-old group, p = 0.854; 30 to 39-year-old group, p = 0.191, 40 to 49-year-old group, p = 0.749; 50 to 59-year-old group, p = 0.627; ≥90-year-old group, p = 1.000).

Conclusions

The presence of tonsilloliths was related to the extent of periodontitis because the structures were responding dynamically.
Assessment of water, sanitation, and hygiene among women living in precarious households in a Turkish urban area
Authors: Şimşek Sera , Öcek Zeliha Aslı , Türk Meral , Ünver Ayşegül
Published: January 2024

Background

This study aimed to identify the determinants of water, sanitation, and hygiene (WASH) behaviors and conditions among women in poor neighborhoods in Izmir, Turkey, and to develop a scale for assessing WASH behaviors and conditions that is specifically designed for use in precarious urban areas.

Methods

The study used a cross-sectional design, as well as a methodological feature for developing the scale. The sample size was calculated as 243 households out of 2667 households in the Basmane neighborhood, with a 95% confidence interval and a 6% margin of error, and a woman who was responsible for cleaning was invited to participate from each household. The scales for WASH behaviors and conditions, which served as dependent variables, were developed in a four-stage process, yielding two distinct scales. The WASH-Behaviors Scale had 14 items about hand, body, and home hygiene, whereas the WASH-Conditions in Households Scale included 16 items about variables like area per capita, physical structure, and cleaning tool availability. Age, ethnicity, number of children, education, work status, and income were among the independent variables. Data was collected through household visits. The scales’ validity was evaluated using exploratory factor analysis. Linear logistic regression analysis was employed to assess the determinants of WASH behaviors.

Results

The women, with an average age of 40.65 ± 14.35 years, faced economic challenges, as a substantial portion earned an income below the minimum wage. More than half of them were uninsured, and 72.6% were identified as migrants or refugees. Factor analysis confirmed the compatibility of both scales (KMO = 0.78–0.80, p < 0.05), elucidating 52–54% of the total variance. Factors such as ethnicity, number of children, husband’s education level, income perception, and WASH conditions explained 48% of WASH behaviors.

Conclusions

WASH-Behaviors and WASH-Conditions in Households scales met the validity criterion, and their scores were related to basic sociodemographic and economic characteristics like education, income, household size, and ethnicity. The scale development process emphasized the importance of considering both behaviors and household conditions, albeit using different techniques. The findings indicated that WASH conditions are more problematic than behaviors, and that behavioral interventions will not work unless the conditions are corrected.
Public health and research ethics education: the experience of developing a new cadre of bioethicists at a Ugandan institution
Authors: Kiwanuka Gertrude N. , Bajunirwe Francis , Alele Paul E. , Oloro Joseph , Mindra Arnold , Marshall Patricia , Loue Sana
Published: January 2024

Research ethics education is critical to developing a culture of responsible conduct of research. Many countries in sub-Saharan Africa (SSA) have a high burden of infectious diseases like HIV and malaria; some, like Uganda, have recurring outbreaks. Coupled with the increase in non-communicable diseases, researchers have access to large populations to test new medications and vaccines. The need to develop multi-level capacity in research ethics in Uganda is still huge, being compounded by the high burden of disease and challenging public health issues. Only a few institutions in the SSA offer graduate training in research ethics, implying that the proposed ideal of each high-volume research ethics committee having at least one member with in-depth training in ethics is far from reality. Finding best practices for comparable situations and training requirements is challenging because there is currently no “gold standard” for teaching research ethics and little published information on curriculum and implementation strategies. The purpose of this paper is to describe a model of research ethics (RE) education as a track in an existing 2-year Master of Public Health (MPH) to provide training for developing specific applied learning skills to address contemporary and emerging needs for biomedical and public health research in a highly disease-burdened country. We describe our five-year experience in successful implementation of the MPH-RE program by the Mbarara University Research Ethics Education Program at Mbarara University of Science and Technology in southwestern Uganda. We used curriculum materials, applications to the program, post-training and external evaluations, and annual reports for this work. This model can be adapted and used elsewhere in developing countries with similar contexts. Establishing an interface between public health and research ethics requires integration of the two early in the delivery of the MPH-RE program to prevent a disconnect in knowledge between research methods provided by the MPH component of the MPH-RE program and for research in ethics that MPH-RE students are expected to perform for their dissertation. Promoting bioethics education, which is multi-disciplinary, in institutions where it is still “foreign” is challenging and necessitates supportive leadership at all institutional levels.
Latinas in medicine: evaluating and understanding the experience of Latinas in medical education: a cross sectional survey
Authors: Geiger Gabriella , Kiel Lauren , Horiguchi Miki , Martinez-Aceves Celia , Meza Kelly , Christophers Briana , Orellana Priscilla , Pinzon Maria Mora , Lubner Sam J. , Florez Narjust
Published: January 2024

Background

The percentage of physicians identifying as Latina has not improved despite improvements in recruitment of Latina medical students, suggesting barriers to retention and career advancement. Discriminatory experiences and mental health inflictions throughout training may contribute to difficulties in recruitment, retainment, and advancement of Hispanic/Latinx trainees, a notably understudied population.

Methods

An anonymous, online survey was distributed to Latinas in the continental U.S. between June 22 to August 12, 2022. Eligibility criteria included: self-identifying as Hispanic/Latina, female/woman, and completing or have completed medical school, residency, or fellowship in the continental U.S. in the past 10 years. Recruitment was done via the Twitter account @LatinasInMed and outreach to Latino Medical Student Association chapters. Descriptive statistics summarized the self-reported experiences.

Results

The survey included 230 Hispanic/Latinx women, mostly medical students (46.9%). A majority (54.5%) reported negative ethnicity-based interactions from patients and/or patients’ families; 71.8%, from others in the medical field. High rates of depression (76.2%) and anxiety (92.6%) during training were reported by Latinas, especially medical students. Feelings of imposter syndrome and burnout were high at 90.7% and 87.4%, respectively.

Conclusions

This is the first study evaluating the unique experiences of Latinas in medicine, who reported discrimination and mental health struggles, specifically during medical school, at alarmingly high rates. Our findings could aid in creating the needed interventions to support Latinas in medical training to reduce the existing exodus of Latinas from medicine.
Medical student experiences of equality, diversity, and inclusion: content analysis of student feedback using Bronfenbrenner’s ecological systems theory
Authors: Nolan Helen Anne , Owen Katherine
Published: January 2024

Background

Issues relating to equality, diversity, and inclusion (EDI) significantly impact on medical student achievement and wellbeing. Interventions have been introduced at curricular and organisational levels, yet progress in addressing these issues remains limited. Timely evaluation is needed to assess effectiveness of interventions, and to explore issues and interactions in learning environments impacting on student experience. We introduced an anonymous question concerning students’ experiences of EDI into routine online student feedback questionnaires, to scope the nature of ongoing issues and develop greater understanding of students’ experiences in our programme environment. Ecological systems theory, which conceptualizes learning as a function of complex social interactions, determined by characteristics of individual learners and their environment, provides a framework for understanding.

Methods

Free-text responses regarding experiences of EDI gathered over 20 months from all programme years (n = 760) were pooled for analysis, providing a holistic overview of experiences in the learning environment. A counting exercise identified broad categories reported by students. Content analysis of the qualitative dataset was undertaken. Bronfenbrenner’s ecological systems theory was applied as a framework to demonstrate interdependencies between respondents’ experiences and environments, and associated impacts.

Results

Three hundred and seventy-six responses were received relating to wide-ranging EDI issues, most frequently gender or ethnicity. Responses mapped onto all areas of the ecological systems model, with frequent links between subsystems, indicating considerable complexity and interdependencies. Interpersonal interactions and associated impacts like exclusion were frequently discussed. Differential experiences of EDI-related issues in medical school compared to clinical settings were reported. Impacts of institutional leadership and wider societal norms were considered by respondents. Respondents discussed their need for awareness of EDI with reference to future professional practice.

Conclusions

Implementation of a regular free-text evaluation question allowed data-gathering across cohorts and throughout several stages of the curriculum, illuminating student experience. Connections established demonstrated intersectionality, and how environment and other factors interact, impacting on student experiences. Students experience EDI-related issues on multiple levels within the educational environment, with consequent impacts on learning. Any successful approach towards tackling issues and promoting equity of opportunity for all requires multi-level actions and widespread culture change. Students can offer fresh and distinct perspectives regarding change needed, to complement and diversify perspectives provided by staff and organisational leadership. Student voice should be enabled to shape change.

Published: January 2024

Background and aims

Genetic knowledge and familiarity among the population represent the lane toward effective participation in social decisions regarding genetic issues. This cross sectional research aimed to assess genetic knowledge and familiarity among university students in Palestine.

Methods

The familiarity with genetics was evaluated using the Genetic Literacy and Comprehension instrument (GLAC), and genetic knowledge was measured using a 16-item scale of prevalent genetic concepts.

Results

Among the 624 participants, 59.5% were females. 38.8% reported family history of genetic diseases. The genetic familiarity mean score was 4.83 and the genetic knowledge mean total score was 11.5. Students’ genetic familiarity was high for the terms chromosome and genetic while it was low for the terms sporadic and vulnerability. Genetic knowledge was highest for gene definition while it was the lowest regarding the number of human genes. The age group, year of study, and learning genetic courses were the significant predictors of familiarity among medical students. The year of study, family history of genetic diseases, parental consanguinity, and learning genetic courses were the significant variables associated with genetic knowledge among medical students. Regarding the non-medical group of participants, all study variables were significant for both familiarity and knowledge scores except for age group with familiarity.

Conclusion

Genetic familiarity and knowledge among Palestinian university students are inadequate. Consanguinity and hereditary disorders are prevalent in Palestine. These findings encourage university stakeholders to take action to improve genetic knowledge and familiarity among students through both appropriate pedagogical and non-pedagogical interventions.
“I’ll meet you at our bench”: adaptation, innovation and resilience among VCSE organisations who supported marginalised and minoritised communities during the Covid-19 pandemic in Northern England – a qualitative focus group study
Authors: Scott S , McGowan VJ , Wildman J , Bidmead E , Hartley J , Mathews C , James B , Sullivan C , Bambra C , Sowden S
Published: January 2024

Background

The Covid-19 pandemic has exacerbated pre-existing inequalities and increased adversity and challenges for vulnerable and marginalised communities worldwide. In the UK, the Voluntary Community and Social Enterprise (VCSE) sector play a vital role in supporting the health and wellbeing of people who are marginalised or experiencing multiple complex needs. However, only a small number of studies have focused on the impact that Covid-19 had on the VCSE sector.

Methods

As part of a Health Inequalities Impact Assessment (HIIA), we conducted qualitative focus groups with staff and volunteers from five organisations to examine short, medium and longer-term impacts of Covid-19 upon the VCSE sector in Northern England. Nine online focus groups were conducted between March and July 2021.

Findings

Focus group transcripts were analysed using Framework Analysis and yielded three central themes: (1) exacerbation of pre-existing inequalities, adversity and challenges for vulnerable and marginalised populations; (2) the ‘price’ of being flexible, innovative and agile for VCSE staff and volunteers; and (3) the voluntary sector as a ‘lifeline’ - organisational pride and resilience.

Conclusions

While the voluntary sector ‘adapted at pace’ to provide support during Covid-19 and in its continued aftermath, this resilience has potentially come at the cost of workforce and volunteer wellbeing, compounded by political obstacles and chronic shortage in funding and support. The VCSE sector has a vital role to play in the post-lockdown ‘levelling up’ agenda. The expertise, capacity and resilience of VCSE organisations, and their ability to respond to Covid-19, should be celebrated, recognised and supported adequately to maintain its resilience. To not do so threatens the sector’s sustainability and risks jeopardising attempts to involve the sector in addressing the social determinants of health.

Published: January 2024

Background

Pregnancy toxemia is a common disease, which occurs in older does that are pregnant with multiple lambs in the third trimester. Most of the sick goats die within a few days, which can seriously impact the economic benefits of goat breeding enterprises. The disease is believed to be caused by malnutrition, stress, and other factors, that lead to the disorder of lipid metabolism, resulting in increased ketone content, ketosis, ketonuria, and neurological symptoms. However, the changes in gut microbes and their metabolism in this disease are still unclear. The objective of this experiment was to evaluate the effect of toxemia of pregnancy on the fecal microbiome and metabolomics of does.

Results

Eight pregnant does suspected of having toxemia of pregnancy (PT group) and eight healthy does during the same pregnancy (NC group) were selected. Clinical symptoms and pathological changes at necropsy were observed, and liver tissue samples were collected for pathological sections. Jugular venous blood was collected before morning feeding to detect biochemical indexes. Autopsy revealed that the liver of the pregnancy toxemia goat was enlarged and earthy yellow, and the biochemical results showed that the serum levels of aspartate aminotransferase (AST) and β-hydroxybutyric acid (B-HB) in the PT group were significantly increased, while calcium (Ca) levels were significantly reduced. Sections showed extensive vacuoles in liver tissue sections. The microbiome analysis found that the richness and diversity of the PT microbiota were significantly reduced. Metabolomic analysis showed that 125 differential metabolites were screened in positive ion mode and enriched in 12 metabolic pathways. In negative ion mode, 100 differential metabolites were screened and enriched in 7 metabolic pathways.

Conclusions

Evidence has shown that the occurrence of pregnancy toxemia is related to gut microbiota, and further studies are needed to investigate its pathogenesis and provide research basis for future preventive measures of this disease.

Background

The Acute Respiratory Distress Syndrome (ARDS) is characterized by lung inflammation and edema, impairing both oxygenation and lung compliance. Recent studies reported a dissociation between oxygenation and compliance (severe hypoxemia with preserved compliance) in early ARDS and COVID-19-related-ARDS (CARDS). During the pandemic, in patients requiring prolonged mechanical ventilation, we observed the opposite combination (mild-moderate hypoxemia but significantly impaired compliance). The purpose of our study was to investigate the prevalence of this combination of mild-moderate hypoxemia and impaired compliance in persistent ARDS and CARDS.

Methods

For this retrospective study, we used individual patient-level data from two independent cohorts of ARDS patients. The ARDSNet cohort included patients from four ARDS Network randomized controlled trials. The CARDS cohort included patients with ARDS due to COVID-19 hospitalized in two intensive care units in Greece. We used a threshold of 150 for PaO2/FiO2 and 30 ml/cmH2O for compliance, estimated the prevalence of each of the four combinations of oxygenation and compliance at baseline, and examined the change in its prevalence from baseline to day 21 in the ARDSNet and CARDS cohorts.

Results

The ARDSNet cohort included 2909 patients and the CARDS cohort included 349 patients. The prevalence of the combination of mild-moderate hypoxemia and low compliance increased from baseline to day 21 both in the ARDSNet cohort (from 22.2 to 42.7%) and in the CARDS cohort (from 3.1 to 33.3%). Among surviving patients with low compliance, oxygenation improved over time. The 60-day mortality rate was higher for patients who had mild-moderate hypoxemia and low compliance on day 21 (28% and 56% in ARDSNet and CARDS), compared to those who had mild-moderate hypoxemia and high compliance (20% and 50%, respectively).

Conclusions

Among patients with ARDS who require prolonged controlled mechanical ventilation, regardless of ARDS etiology, a dissociation between oxygenation and compliance characterized by mild-moderate hypoxemia but low compliance becomes increasingly prevalent. The findings of this study highlight the importance of monitoring mechanics in patients with persistent ARDS.
