Introduction

Selective serotonin reuptake inhibitors (SSRIs) are widely used for the treatment of various mental disorders. Sexual dysfunction is one of the most common side effects of SSRIs, and often leads to poor adherence and treatment discontinuation. While several strategies have been employed to manage SSRI-induced sexual dysfunction, drug holidays has not been extensively studied for this purpose. This clinical trial aims to assess the effect of drug holidays on sexual dysfunction in married men under treatment with SSRIs other than fluoxetine (as its long half-life makes drug holidays ineffective).

Methods

This 8-week double-center, randomized, open-label, controlled trial was conducted in the outpatient clinics of Iran Psychiatric Hospital and Tehran Institute of Psychiatry, from January 2022 to March 2023. We included married men aged between18 and 50 years who had experienced sexual dysfunction during treatment with SSRIs, other than fluoxetine. The Male Sexual Health Questionnaire (MSHQ) and the 28-Question General Health Questionnaire (GHQ-28) were used for the assessment of sexual function and mental health status. The drug holidays group was instructed not to take their medications on the weekends. The control group was asked to continue their regular medication regimen without any changes. Both groups were assessed at baseline, and weeks 4 and 8.

Results

Sixty-three patients were included and randomly assigned to the drug holidays group (N = 32) or the control group (N = 31). Fifty patients (25 in each group) completed the trial. Drug holidays significantly improved erection, ejaculation, satisfaction, and the overall sexual health of the participants (P < 0.001). No significant change was observed in their mental health status. No major side effects were recorded.

Conclusions

Drug holidays significantly improved the MSHQ scores in ‘erection’, ‘ejaculation’, ‘satisfaction’ and ‘total’ in married men with sexual dysfunction induced by SSRIs, other than fluoxetine, without causing any significant changes in their mental health status. Further research is needed to reach a certain conclusion.

Trial registration

The trial was registered at the Iranian Registry of Clinical Trials on 2021.10.25 (www.irct.ir; IRCT ID: IRCT20170123032145N6) before the trial.

Published: January 2024

Background

Improving family planning and maternal health outcomes are critical to achieving the Sustainable Development Goals. While evidence on the effectiveness of government-driven public health programs is extensive, more research is needed on effectiveness of private-sector interventions, especially in low- and middle-income countries. We evaluated the impacts of a commercial social-franchising and social-marketing program – Tiko Platform – which created a local ecosystem of health promoters, healthcare providers, pharmacies, stockists/wholesalers, and lifestyle shops. It provided economic incentives through discounts and reward points to nudge health-seeking behaviors from enrolled women consumers/beneficiaries.

Methods

An ex-post facto evaluation was commissioned, and we employed a quasi-experimental design to compare outcomes related to the use of family planning, and antenatal and postnatal services between users and non-users who had registered for Tiko in three North Indian cities. Between March and April 2021, 1514 married women were surveyed, and outcome indicators were constructed based on recall. Despite statistical approaches to control for confounding, the effect of COVID-19 lockdown on Tiko operations and methodological limitations preclude inferring causality or arguing generalizability.

Results

We found a strong association between the use of the Tiko platform and the current use of temporary modern contraceptives [non-users: 9.5%, effect: +9.4 percentage points (pp), p-value < 0.001], consumption of 100 or more iron-folic-acid tablets during pregnancy [non-users: 25.5%, effect: +14 pp, p-value < 0.001], receiving four or more antenatal check-ups [non-users: 18.3%, effect: +11.3 pp, p-value 0.007], and receiving postnatal check-up within six weeks of birth [non-users: 50.9%, effect: +7.5 pp, p-value 0.091]. No associations were found between the use of the Tiko platform and the current use of any type of contraceptive (temporary, permanent, or rudimentary). Effects were pronounced when a community health worker of the National Health Mission also worked as a health promoter for the Tiko Platform.

Conclusion

Commercial interventions that harness market-driven approaches of incentives, social marketing, and social franchising improved family planning and maternal health practices through higher utilization of private market providers while maintaining access to government health services. Findings support a unifying approach to public health without separating government versus private services, but more rigorous and generalizable research is needed.

Epidemiology of multimorbidity associated with atherosclerotic cardiovascular disease in the United States, 1999–2018
Authors: Tian Ying , Li Dongna , Cui Haoliang , Zhang Xin , Fan Xiaoyan , Lu Feng
Published: January 2024

Background

The multimorbidity of Atherosclerotic cardiovascular disease (ASCVD) and many other chronic conditions is becoming common. This study aimed to assess multimorbidity distribution in ASCVD among adults in the United States from 1999 to 2018.

Methods

This cross-sectional survey from the National Health and Nutrition Examination Survey (NHANES) 1999–2018 using stratified multistage probability design. Among the 53,083 survey respondents during the study period, 5,729 US adults aged ≥ 20 years with ASCVD. Joinpoint regression was used to assess the statistical significance of prevalence trends in the prevalence of ASCVD stratified by multimorbidity. The Apriori association rule mining algorithm was used to identify common multimorbidity association patterns in ASCVD patients.

Results

Overall, 5,729 of 53,083 individuals had ASCVD, and the prevalence showed a slow declining trend (biannual percentage change = -0.81%, p = 0.035, average 7.71%). The prevalence of ASCVD significantly decreased in populations without dyslipidemia, diabetes mellitus (DM), hypertension, asthma, chronic obstructive pulmonary disease (COPD), and arthritis (all groups, p < 0.05). Additionally, 65.6% of ASCVD patients had at least four of the 12 selected chronic conditions, with four and five being the most common numbers of conditions (17.9% and 17.7%, respectively). The five most common chronic conditions were (in order) dyslipidemia, hypertension, arthritis, chronic kidney disease, and DM. The coexistence of hypertension and dyslipidemia had the highest support in association rules (support = 0.63), while the coexistence of dyslipidemia, hypertension, metabolic syndrome, and DM had the highest lift (lift = 1.82).

Conclusions

During the 20-year survey period, there was a significant decrease in the overall prevalence of ASCVD. However, this reduction was primarily observed in individuals without dyslipidemia, DM, hypertension, asthma, COPD, and arthritis. Among populations with any of the evaluated chronic conditions, the prevalence of ASCVD remained unchanged. Most of ASCVD patients had four or more concurrent chronic conditions.
Home-delivered meal boxes in a family setting: a qualitative study investigating reasons for use and perceived impact on meal practices
Authors: Vos Marjolijn , Deforche Benedicte , Van Lippevelde Wendy
Published: January 2024

Background

Cooking and consuming a homemade meal is associated with health benefits. Home-delivered meal boxes can support families in cooking this fresh meal. The current study aimed to gain a deeper understanding of the determinants of meal box use, and of the perceived impact on meal practices of parents with younger (i.e., aged 6–12 years) and older children (i.e., 13–18 years).

Methods

Four focus groups were conducted (n = 19); two with parents of younger children, and two with parents of older children. A semi-structured interview guide was developed and interviews were recorded and transcribed. Reflexive thematic analysis was performed using NVivo 1.4.

Results

Most parents mentioned practical reasons like saving time and money, as well as inspiration, as reasons to choose a home-delivered meal box. Also, tastiness and menu variation were often mentioned as determining factors by both parent groups. However, a few parents stated to stop using the meal boxes because of returning menus or too small portion sizes. Meal box providers were chosen based on the price, the freshness and the quality of the products. Moreover, positive effects on parents’ perceived cooking skills and knowledge were reported. Also, some parents mentioned positively changed attitudes towards vegetarian dishes. Lastly, parents reported healthier eating due to more appropriate portion sizes and more vegetables. A prominent difference between parent groups was that older children played a role in continuing the use of meal boxes, and helped to prepare the meals (contrary to younger children).

Conclusions

Home-delivered meal boxes might be promising to enhance families’ meal practices. This study could inform social marketeers and health promotors to adopt an optimal strategy to reach families.
Factors associated with perceived work-life balance among health workers in Gulu District, Northern Uganda: a health facility-based cross-sectional study

Published: January 2024

Introduction

Work-life balance (WLB) plays a significant role in improving career satisfaction and reducing burnout. While health workers’ productivity is considered a key factor in client care, there is limited effort put into examining how health workers perceive the balance of their jobs with family and other societal responsibilities (PWLB), especially in low-income countries where the number of health workers in active patient care is low. The purpose of this study was to assess factors associated with perceived work-life balance (PWLB) among health workers in the rural district of Gulu, Northern Uganda.

Methods

A health facility-based cross-sectional analytical study was conducted. A simple random sampling technique was used to select 384 study participants from the three main hospitals in Gulu District. Data were collected from health workers using a self-administered semi-structured questionnaire and analyzed using STATA version 15. Factors associated with PWLB were determined at a multivariable level using a modified Poisson regression with robust variance with a 95% confidence level and 5% statistical significance. Adjusted prevalent ratios (APR) were used to report the Factors associated with PWLB.

Results

Only 157/384 (40.9%) of the health workers reported a positive perceived work-life balance. Multivariable modified Poisson regression analysis showed positive statistical association with PWLB of a laboratory worker(APR = 1.74, 95% CI: 1.10–2.75); a midwife(APR = 1.82, 95% CI:1.13–2.93) or a nurse (APR = 2.19, 95% CI = 1.45–3.30); working in the inpatient department (APR = 1.97, 95% CI: 1.31–2.96) or laboratory (APR = 2.09, 95%CI: 1.34–3.28); and having a flexible work schedule (APR = 28.32, 95%CI:14.52–55.22); feeling satisfied at work (APR = 1.58; 95% CI:1.17–2.10), and belonging to an association in the community (APR = 32.71, 95% Cl:11.91–89.88). On the other hand, employment tenure of 1–4 years (APR = 0.63,95% CI:0.40–0.99) was negatively associated with perceived work-life balance.

Conclusion

Only four in every 10 health workers experienced a positive perceived work-life balance. The type of profession, duty station, flexibility in work schedule, satisfaction with work, and availability of social support systems, were independent determinants of perceived WLB. Therefore, nurturing a system of reviews of the scheduling of health workers, allowing internal staff rotation, and fostering support systems around the health workers could be beneficial for WLB.
Exploring the relationship between loneliness and volunteering amongst Australian adults: a cross-sectional study
Authors: Williams Tara , Lakhani Ali , Spelten Evelien
Published: January 2024

Background

Alleviating loneliness and fostering social connections and a sense of belonging are essential for individuals’ well-being in the aftermath of the COVID-19 pandemic. Volunteering has emerged as a potential strategy to prevent or alleviate loneliness among adults. To gain insights into factors that can reduce or protect against loneliness, it is important to consider multi-dimensional measures of loneliness and motivations to volunteer. This study aimed to understand which variables predict Australian volunteers’ social, family, and romantic loneliness.

Methods

From October 2021 to January 2022, a cross-sectional online survey was administered to a sample of Australian adults with volunteering experience. The survey collected demographic information and used validated measures to assess social, family, and romantic loneliness and volunteer motivation. Bivariate and multivariate analyses were conducted to examine the association between loneliness and motivations for volunteering.

Results

Of the 1723 individuals who accessed the survey link, 160 participants completed the survey. The average age of respondents was 59.87 years (SD 12.3). The majority were female (77.5%), married or partnered (70.6%), and had ten or more years of volunteering experience (62.1%). Overall, participants reported low to moderate levels of loneliness across social (M = 12.1; SD = 5.3), family (M = 11.3; SD = 6.7), and romantic (M = 14.8; SD = 8.3) dimensions. Social motivation for volunteering was negatively associated with social and romantic loneliness, while enhancement and protective motivations were positively associated with family and romantic loneliness. Age and rurality were not significantly associated with any dimension of loneliness.

Conclusions

Loneliness is a multifaceted and intricate experience that impacts individuals socially and emotionally. This study’s findings confirmed that having protective and enhancement motives to volunteer was associated with increased loneliness. Social motives to volunteer were associated with a tendency to have lower levels of loneliness, possibly due to the positive impact of building and maintaining social relationships through volunteering. Understanding these associations is necessary to ensure that volunteering activities align with each person’s unique needs and motivations.

Authors: Lee Hyo Jin , Lee Jung-Kyu , Park Tae Yeon , Heo Eun Young , Kim Deog Kyeom , Lee Hyun Woo
Published: January 2024

Background and objectives

Few studies have reported which inhaled combination therapy, either bronchodilators and/or inhaled corticosteroids (ICSs), is beneficial in patients with bronchiectasis and airflow obstruction. Our study compared the efficacy and safety among different inhaled combination therapies in patients with bronchiectasis and airflow obstruction.

Methods

Our retrospective study analyzed the patients with forced expiratory volume in 1 s (FEV1)/forced vital capacity < 0.7 and radiologically confirmed bronchiectasis in chest computed tomography between January 2005 and December 2021. The eligible patients underwent baseline and follow-up spirometric assessments. The primary endpoint was the development of a moderate-to-severe exacerbation. The secondary endpoints were the change in the annual FEV1 and the adverse events. Subgroup analyses were performed according to the blood eosinophil count (BEC).

Results

Among 179 patients, the ICS/long-acting beta-agonist (LABA)/long-acting muscarinic antagonist (LAMA), ICS/LABA, and LABA/LAMA groups were comprised of 58 (32.4%), 52 (29.1%), and 69 (38.5%) patients, respectively. ICS/LABA/LAMA group had a higher severity of bronchiectasis and airflow obstruction, than other groups. In the subgroup with BEC ≥ 300/uL, the risk of moderate-to-severe exacerbation was lower in the ICS/LABA/LAMA group (adjusted HR = 0.137 [95% CI = 0.034–0.553]) and the ICS/LABA group (adjusted HR = 0.196 [95% CI = 0.045–0.861]) compared with the LABA/LAMA group. The annual FEV1 decline rate was significantly worsened in the ICS/LABA group compared to the LABA/LAMA group (adjusted β-coefficient=-197 [95% CI=-307–-87]) in the subgroup with BEC < 200/uL.

Conclusion

In patients with bronchiectasis and airflow obstruction, the use of ICS/LABA/LAMA and ICS/LABA demonstrated a reduced risk of exacerbation compared to LABA/LAMA therapy in those with BEC ≥ 300/uL. Conversely, for those with BEC < 200/uL, the use of ICS/LABA was associated with an accelerated decline in FEV1 in comparison to LABA/LAMA therapy. Further assessment of BEC is necessary as a potential biomarker for the use of ICS in patients with bronchiectasis and airflow obstruction.
Applications of artificial intelligence in the field of oral and maxillofacial pathology: a systematic review and meta-analysis
Authors: Abdul Nishath Sayed , Shivakumar Ganiga Channaiah , Sangappa Sunila Bukanakere , Di Blasio Marco , Crimi Salvatore , Cicciù Marco , Minervini Giuseppe
Published: January 2024

Background

Since AI algorithms can analyze patient data, medical records, and imaging results to suggest treatment plans and predict outcomes, they have the potential to support pathologists and clinicians in the diagnosis and treatment of oral and maxillofacial pathologies, just like every other area of life in which it is being used. The goal of the current study was to examine all of the trends being investigated in the area of oral and maxillofacial pathology where AI has been possibly involved in helping practitioners.

Methods

We started by defining the important terms in our investigation's subject matter. Following that, relevant databases like PubMed, Scopus, and Web of Science were searched using keywords and synonyms for each concept, such as "machine learning," "diagnosis," "treatment planning," "image analysis," "predictive modelling," and "patient monitoring." For more papers and sources, Google Scholar was also used.

Results

The majority of the 9 studies that were chosen were on how AI can be utilized to diagnose malignant tumors of the oral cavity. AI was especially helpful in creating prediction models that aided pathologists and clinicians in foreseeing the development of oral and maxillofacial pathology in specific patients. Additionally, predictive models accurately identified patients who have a high risk of developing oral cancer as well as the likelihood of the disease returning after treatment.

Conclusions

In the field of oral and maxillofacial pathology, AI has the potential to enhance diagnostic precision, personalize care, and ultimately improve patient outcomes. The development and application of AI in healthcare, however, necessitates careful consideration of ethical, legal, and regulatory challenges. Additionally, because AI is still a relatively new technology, caution must be taken when applying it to this industry.
From teeth to brain: dental caries causally affects the cortical thickness of the banks of the superior temporal sulcus
Authors: Wang Mengqiao , Wang Ziyao , Yu Yajie , Zhao Delu , Shen Zhiyuan , Wei Fulan
Published: January 2024

Objectives

Dental caries is one of the most prevalent oral diseases and causes of tooth loss. Cross-sectional studies observed epidemiological associations between dental caries and brain degeneration disorders, while it is unknown whether dental caries causally affect the cerebral structures. This study tested whether genetically proxied DMFS (the sum of Decayed, Missing, and Filled tooth Surfaces) causally impacts the brain cortical structure using Mendelian randomization (MR).

Methods

The summary-level GWAS meta-analysis data from the GLIDE consortium were used for DMFS, including 26,792 participants. ENIGMA (Enhancing NeuroImaging Genetics through Meta Analysis) consortium GWAS summary data of 51,665 patients were used for brain structure. This study estimated the causal effects of DMFS on the surface area (SA) and thickness (TH) of the global cortex and functional cortical regions accessed by magnetic resonance imaging (MRI). Inverse-variance weighted (IVW) was used as the primary estimate, the MR pleiotropy residual sum and outlier (MR-PRESSO), the MR-Egger intercept test, and leave-one-out analyses were used to examine the potential horizontal pleiotropy.

Results

Genetically proxied DMFS decreases the TH of the banks of the superior temporal sulcus (BANSSTS) with or without global weighted (weighted, β = − 0.0277 mm, 95% CI: − 0.0470 mm to − 0.0085 mm, P = 0.0047; unweighted, β = − 0.0311 mm, 95% CI: − 0.0609 mm to − 0.0012 mm, P = 0.0412). The causal associations were robust in various sensitivity analyses.

Conclusions

Dental caries causally decrease the cerebral cortical thickness of the BANKSSTS, a cerebral cortical region crucial for language-related functions, and is the most affected brain region in Alzheimer’s disease. This investigation provides the first evidence that dental caries causally affects brain structure, proving the existence of teeth-brain axes. This study also suggested that clinicians should highlight the causal effects of dental caries on brain disorders during the diagnosis and treatments, the cortical thickness of BANKSSTS is a promising diagnostic measurement for dental caries-related brain degeneration.
The role of adverse childhood experiences in predicting child abuse perpetration among married mothers in Alexandria, Egypt: a cross-sectional study
Authors: Mohammed Yasmine Yousry , Abu-Nazel Mervat Wagdy , Aly Reham Said Ibrahim , Shata Zeinab Nazeeh
Published: January 2024

Background

Adverse childhood experiences (ACEs) are receiving increased amounts of attention as a critical public health issue. ACEs have a massive impact on future violence victimization and perpetration. They are also associated with lifelong mental and physical health consequences as well as premature mortality. The present study aimed to investigate the role of different ACEs among married mothers in predicting the risk of child abuse perpetration in offspring.

Methods

A cross-sectional study was conducted on 350 mothers of children aged 2–12 years attending family health centres in Alexandria. The mothers completed a predesigned interview questionnaire on sociodemographic data and data related to ACEs, spousal violence, and child abuse perpetration. Suitable bivariate and multivariate statistical tests were used to analyse the collected data using version 20.0 of the Statistical Package for Social Sciences (SPSS).

Results

Two-thirds of mothers (66.3%) reported ever having been exposed to any ACE, and 18.6% of them had experienced 3 or more ACEs. Psychological abuse (46%) and witnessing domestic violence (17%) were the most common. Psychological aggression (95.4%), minor physical assault (79%), and neglect (52%) were the most common forms of child abuse perpetrated by the mothers. The number of ACEs experienced by mothers showed a moderate positive significant correlation with the 5 forms of child abuse examined. Different ACEs, mother’s age, socioeconomic status, and current exposure to spousal violence were found to be independent predictors of different forms of child abuse (psychological aggression, neglect, minor physical assault, and severe physical assault).

Conclusion

Different practices of family violence are strongly connected throughout different stages of an individual’s life and across generations. Further understanding of the interconnections among forms of violence and addressing them should be prioritized. Additionally, concerted national strategies across all levels and sectors are needed to address this complex problem.
U-shaped association between serum 25-hydroxyvitamin D concentrations and urinary leakage among adult females aged 45 years and over in the United States: a cross-sectional study
Authors: Li Zeyu , Lu Xinzhuo , Zhang Keshuai , Wu Shuangyan , Yu Wei , Chen Xiaoling , Zheng Wenzhong
Published: January 2024

Background

The relationship between serum vitamin D status and urinary leakage (UL) among middle-aged females needs to be further studied. The aim of this study was to evaluate the association of serum 25-hydroxyvitamin D [25(OH)D] concentrations with UL among American females ages 45 years and over.

Methods

Seven cycles of the National Health and Nutrition Examination Survey (NHANES) with self-report UL data, were used. A total of 9525 women aged 45 years and older were enrolled in this study. Univariate and multivariate logistic regression models and the smooth curve fitting were utilized to analyze the association between clinical UL and serum 25-hydroxyvitamin D [25(OH)D] concentrations.

Results

A non-linear relationship between serum 25(OH)D concentrations and clinical ULwas observed. When serum 25(OH)D concentration was higher than the inflection point 63.5 nmol/L, a positive correlation was observed between serum 25(OH)D concentrations and clinical UL ([OR]: 1.007, 95%CI: 1.005–1.009, P < 0.01). However, when serum 25(OH)D concentration was below the inflection point 63.5 nmol/L, a negative correlation was observed between serum 25(OH)D concentrations and clinical UL ([OR]: 0.993, 95%CI: 0.989–0.996, P < 0.01).

Conclusions

The association between serum vitamin D and the risk of UL exhibited a U-shaped pattern among US middle-aged females, with an inflection point occurring at a serum 25(OH)D concentration of 63.5 nmol/L.

Tasdik
Published: January 2024

Aim

This study aimed to investigate the career preferences among Bangladeshi medical students, identify the factors that influence their present choices, and additionally report the role of gender and academic year behind their decisions.

Methods

This cross-sectional study conducted in Bangladesh from August 2022 to April 2023 included 801 medical students conveniently selected from medical colleges in eight divisions. Data were collected using a web-based survey and analysed using STATA version 16.0. Statistical tests included the Kolmogorov-Smirnov test, arithmetic mean, standard deviation, frequency, and Kruskal-Wallis H test. The response rate was 94.6%, and the CHERRIES guideline was followed for reporting the results.

Result

The majority of the participants were female (64.42%) and under the age of 23 years (58.8%). The study revealed that medicine was the preferred career choice for the majority of students (65%), with surgery being the most popular first choice (30.21%) among them. Female medical students showed a significantly higher preference for gynaecology & obstetrics (p < 0.001), while male students had a significantly higher tendency to choose general practice (p = 0.002). There is a significant gender difference (p < 0.05) in the career preference factors, including professional prestige, role model influence, easy money, family time, promotion opportunities, income for lifestyle, and research opportunities. Academic year differences were also observed, with increasing interest in medicine and public health (p < 0.001), a decrease in interest in surgery (p < 0.001), and a decline in preference for non-medical careers as students progressed through their MBBS life (p < 0.05).

Conclusion

Overall, medicine was the most popular speciality choice, however, male students preferred general practice and female students preferred gynaecology and obstetrics more. Personal passion, opportunities for contribution to society, professional prestige, having a direct dealing with patients, and income will allow an enjoyable lifestyle were the most important factors in the choice of their career.
Integrating ethics in AI development: a qualitative study
Authors: Arbelaez Ossa Laura , Lorenzini Giorgia , Milford Stephen R. , Shaw David , Elger Bernice S. , Rost Michael
Published: January 2024

Background

While the theoretical benefits and harms of Artificial Intelligence (AI) have been widely discussed in academic literature, empirical evidence remains elusive regarding the practical ethical challenges of developing AI for healthcare. Bridging the gap between theory and practice is an essential step in understanding how to ethically align AI for healthcare. Therefore, this research examines the concerns and challenges perceived by experts in developing ethical AI that addresses the healthcare context and needs.

Methods

We conducted semi-structured interviews with 41 AI experts and analyzed the data using reflective thematic analysis.

Results

We developed three themes that expressed the considerations perceived by experts as essential for ensuring AI aligns with ethical practices within healthcare. The first theme explores the ethical significance of introducing AI with a clear and purposeful objective. The second theme focuses on how experts are concerned about the tension that exists between economic incentives and the importance of prioritizing the interests of doctors and patients. The third theme illustrates the need to develop context-sensitive AI for healthcare that is informed by its underlying theoretical foundations.

Conclusions

The three themes collectively emphasized that beyond being innovative, AI must genuinely benefit healthcare and its stakeholders, meaning AI also aligns with intricate and context-specific healthcare practices. Our findings signal that instead of narrow product-specific AI guidance, ethical AI development may need a systemic, proactive perspective that includes the ethical considerations (objectives, actors, and context) and focuses on healthcare applications. Ethically developing AI involves a complex interplay between AI, ethics, healthcare, and multiple stakeholders.
Health seeking behaviours and private sector delivery of care for non-communicable diseases in low- and middle-income countries: a systematic review
Authors: Brindley Callum , Wijemunige Nilmini , Dieteren Charlotte , Bom Judith , Meessen Bruno , Bonfrer Igna
Published: January 2024

Background

Globally, non-communicable diseases (NCDs) are the leading cause of mortality and morbidity placing a huge burden on individuals, families and health systems, especially in low- and middle-income countries (LMICs). This rising disease burden calls for policy responses that engage the entire health care system. This study aims to synthesize evidence on how people with NCDs choose their healthcare providers in LMICs, and the outcomes of these choices, with a focus on private sector delivery.

Methods

A systematic search for literature following PRISMA guidelines was conducted. We extracted and synthesised data on the determinants and outcomes of private health care utilisation for NCDs in LMICs. A quality and risk of bias assessment was performed using the Mixed Methods Appraisal Tool (MMAT).

Results

We identified 115 studies for inclusion. Findings on determinants and outcomes were heterogenous, often based on a particular country context, disease, and provider. The most reported determinants of seeking private NCD care were patients having a higher socioeconomic status; greater availability of services, staff and medicines; convenience including proximity and opening hours; shorter waiting times and perceived quality. Transitioning between public and private facilities is common. Costs to patients were usually far higher in the private sector for both inpatient and outpatient settings. The quality of NCD care seems mixed depending on the disease, facility size and location, as well as the aspect of quality assessed.

Conclusion

Given the limited, mixed and context specific evidence currently available, adapting health service delivery models to respond to NCDs remains a challenge in LMICs. More robust research on health seeking behaviours and outcomes, especially through large multi-country surveys, is needed to inform the effective design of mixed health care systems that effectively engage both public and private providers.

Effective strategies for Fecal Immunochemical Tests (FIT) programs to improve colorectal cancer screening uptake among populations with limited access to the healthcare system: a rapid review
Authors: Belon Ana Paula , McKenzie Emily , Teare Gary , Nykiforuk Candace I. J. , Nieuwendyk Laura , Kim Minji , Lee Bernice , Adhikari Kamala
Published: January 2024

Background

Colorectal cancer (CRC) is one of the leading causes of cancer death globally. CRC screening can reduce the incidence and mortality of CRC. However, socially disadvantaged groups may disproportionately benefit less from screening programs due to their limited access to healthcare. This poor access to healthcare services is further aggravated by intersecting, cumulative social factors associated with their sociocultural background and living conditions. This rapid review systematically reviewed and synthesized evidence on the effectiveness of Fecal Immunochemical Test (FIT) programs in increasing CRC screening in populations who do not have a regular healthcare provider or who have limited healthcare system access.

Methods

We used three databases: Ovid MEDLINE, Embase, and EBSCOhost CINAHL. We searched for systematic reviews, meta-analysis, and quantitative and mixed-methods studies focusing on effectiveness of FIT programs (request or receipt of FIT kit, completion rates of FIT screening, and participation rates in follow-up colonoscopy after FIT positive results). For evidence synthesis, deductive and inductive thematic analysis was conducted. The findings were also classified using the Cochrane Methods Equity PROGRESS-PLUS framework. The quality of the included studies was assessed.

Results

Findings from the 25 included primary studies were organized into three intervention design-focused themes. Delivery of culturally-tailored programs (e.g., use of language and interpretive services) were effective in increasing CRC screening. Regarding the method of delivery for FIT, specific strategies combined with mail-out programs (e.g., motivational screening letter) or in-person delivery (e.g., demonstration of FIT specimen collection procedure) enhanced the success of FIT programs. The follow-up reminder theme (e.g., spaced out and live reminders) were generally effective. Additionally, we found evidence of the social determinants of health affecting FIT uptake (e.g., place of residence, race/ethnicity/culture/language, gender and/or sex).

Conclusions

Findings from this rapid review suggest multicomponent interventions combined with tailored strategies addressing the diverse, unique needs and priorities of the population with no regular healthcare provider or limited access to the healthcare system may be more effective in increasing FIT screening. Decision-makers and practitioners should consider equity and social factors when developing resources and coordinating efforts in the delivery and implementation of FIT screening strategies.

Background

Pathologic scars, including keloids and hypertrophic scars, represent a common form of exaggerated cutaneous scarring that is difficult to prevent or treat effectively. Additionally, the pathobiology of pathologic scars remains poorly understood. We aim at investigating the impact of TEM1 (also known as endosialin or CD248), which is a glycosylated type I transmembrane protein, on development of pathologic scars.

Methods

To investigate the expression of TEM1, we utilized immunofluorescence staining, Western blotting, and single-cell RNA-sequencing (scRNA-seq) techniques. We conducted in vitro cell culture experiments and an in vivo stretch-induced scar mouse model to study the involvement of TEM1 in TGF-β-mediated responses in pathologic scars.

Results

The levels of the protein TEM1 are elevated in both hypertrophic scars and keloids in comparison to normal skin. A re-analysis of scRNA-seq datasets reveals that a major profibrotic subpopulation of keloid and hypertrophic scar fibroblasts greatly expresses TEM1, with expression increasing during fibroblast activation. TEM1 promotes activation, proliferation, and ECM production in human dermal fibroblasts by enhancing TGF-β1 signaling through binding with and stabilizing TGF-β receptors. Global deletion of Tem1 markedly reduces the amount of ECM synthesis and inflammation in a scar in a mouse model of stretch-induced pathologic scarring. The intralesional administration of ontuxizumab, a humanized IgG monoclonal antibody targeting TEM1, significantly decreased both the size and collagen density of keloids.

Conclusions

Our data indicate that TEM1 plays a role in pathologic scarring, with its synergistic effect on the TGF-β signaling contributing to dermal fibroblast activation. Targeting TEM1 may represent a novel therapeutic approach in reducing the morbidity of pathologic scars.
Dietary patterns derived by reduced rank regression are associated with lipid disorders among Korean adults: a cross-sectional analysis
Authors: Kim Hyun Ah , Shin Hye Ran , Song SuJin
Published: January 2024

Background

Lipid disorders are a potent risk factor for cardiovascular diseases. Moreover, the intake of dietary fatty acids has been closely related to blood lipid levels. Therefore, this cross-sectional study examined the associations between dietary patterns related to fatty acid intake and lipid disorders in Korean adults.

Methods

From the 2013–2019 Korea National Health and Nutrition Examination Surveys data, 8399 men and 11404 women (aged ≥ 19 years) were selected. Reduced rank regression was employed to identify dietary patterns from 26 food groups, aiming to explain the maximum variation in the intake of saturated fatty acids (SFA), polyunsaturated fatty acids (PUFA), omega-3 fatty acids, and the PUFA/SFA ratio. Associations of quintiles (Q) of dietary pattern scores with lipid disorders were examined using multiple logistic regression stratified by sex.

Results

Three dietary patterns were identified: dietary pattern 1 showed positive factor loadings for vegetable oils, seasonings, legumes, nuts, and fish; dietary pattern 2 was high in consumption of red meat, bread and snacks, and milk and dairy products; and dietary pattern 3 was rich in fish and milk and dairy products. In men, dietary pattern 3 was inversely associated with elevated triglycerides (Q5 vs. Q1: odds ratio [OR] = 0.82, 95% confidence interval [CI] = 0.69–0.97, P-trend = 0.008). In women, dietary pattern 2 was positively associated with elevated total cholesterol (OR = 1.31, 95% CI = 1.12–1.52, P-trend < 0.001) but inversely associated with low HDL-cholesterol (OR = 0.70, 95% CI = 0.59–0.83, P-trend < 0.001).

Conclusion

In this study, dietary patterns explaining the intake of various types of fatty acids were differentially associated with lipid disorders in Korean adults. Dietary pattern characterized by higher intakes of red meat, bread and snacks and milk and dairy products were positively associated with elevated total cholesterol, whereas dietary pattern rich in fish consumption showed an inverse association with elevated triglycerides. These findings could be instrumental in developing dietary guidelines and strategies for preventing and managing lipid disorders in this population.

Published: January 2024

Background

Periodontitis is a chronic oral inflammatory disease that seriously affects people's quality of life. The purpose of our study was to investigate the correlation between the systemic immune inflammation index (SII) and periodontitis by utilizing a large national survey. This will establish a reference for the early identification and management of periodontitis.

Methods

This study comprised the adult US population who participated in a national periodontitis surveillance project during the six years from 2009 to 2014. Through the utilization of univariate and multivariate weighted logistic regression, we investigated the correlation between the systemic immune inflammation index and periodontitis. Additionally, we employed sensitivity analyses to evaluate the robustness of our findings.

Results

The study involved 10,366 participants with an average age of 51.00 years, of whom 49.45% were male (N = 5126) and 50.55% were female (N = 5240). The prevalence of periodontitis is estimated to be about 38.43% in the US adults aged 30 or older population. Our logistic regression models indicated a positive association between a SII higher than 978 × 109/L and periodontitis. The elder group (aged 50 or older) with SII higher than 978 × 109/L demonstrated a significant correlation with periodontitis in the fully adjusted model (Odds Ratio [OR] = 1.409, 95% Confidence Interval [CI] 1.037, 1.915, P = 0.022). However, there is no statistical difference among adults aged 30 to 50. The robustness of our findings was confirmed through sensitivity analyses.

Conclusions

Our study highlights that SII is associated with periodontitis in a nationally representative sample of US adults. And the SII is significantly associated with a high risk of periodontitis in individuals aged 50 or older.

Published: January 2024

Parkinson’s disease (PD) and Alzheimer’s disease (AD) are neurodegenerative disorders caused by the interaction of genetic, environmental, and familial factors. These diseases have distinct pathologies and symptoms that are linked to specific cell populations in the brain. Notably, the immune system has been implicated in both diseases, with a particular focus on the dysfunction of microglia, the brain’s resident immune cells, contributing to neuronal loss and exacerbating symptoms. Researchers use models of the neuroimmune system to gain a deeper understanding of the physiological and biological aspects of these neurodegenerative diseases and how they progress. Several in vitro and in vivo models, including 2D cultures and animal models, have been utilized. Recently, advancements have been made in optimizing these existing models and developing 3D models and organ-on-a-chip systems, holding tremendous promise in accurately mimicking the intricate intracellular environment. As a result, these models represent a crucial breakthrough in the transformation of current treatments for PD and AD by offering potential for conducting long-term disease-based modeling for therapeutic testing, reducing reliance on animal models, and significantly improving cell viability compared to conventional 2D models. The application of 3D and organ-on-a-chip models in neurodegenerative disease research marks a prosperous step forward, providing a more realistic representation of the complex interactions within the neuroimmune system. Ultimately, these refined models of the neuroimmune system aim to aid in the quest to combat and mitigate the impact of debilitating neuroimmune diseases on patients and their families.

Background

Infection by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and influenza virus is still a major worldwide health concern. Plants are a good source of bioactive compounds to be used as preventive measures for both inhibiting the virus binding and enhancing mucosal innate immunity. Curcumin has been shown to possess antiviral activity and modulate innate immunity. Therefore, the purpose of this study was to develop an oro-nasal film spray containing curcumin and determine its antiviral activity against SARS-CoV-2 and influenza virus infection, as well as its effects on mucosal innate immunity and inflammatory cytokines in vitro.

Methods

The antiviral activity of the film spray against SARS-CoV-2, influenza A/H1N1, A/H3N2, and influenza B was assessed in vitro by plaque reduction assay. Cytotoxicity of the film spray to oral keratinocytes and nasal epithelial cells was assessed by MTT assay, and cytotoxicity to Vero and MDCK cells was assessed by an MTS-based cytotoxicity assay. Oral and nasal innate immune markers in response to the film spray were determined by ELISA and by a commercial Milliplex Map Kit, respectively.

Results

Our data show that the film spray containing curcumin can inhibit both SARS-CoV-2 and influenza virus infections while maintaining cell viability. Results obtained among 4 viruses revealed that curcumin film spray demonstrated the highest inhibitory activity against SARS-CoV-2 with the lowest EC50 of 3.15 µg/ml and the highest SI value of 4.62, followed by influenza B (EC50 = 6.32 µg/ml, SI = 2.04), influenza A/H1N1 (EC50 = 7.24 µg/ml, SI = 1.78), and influenza A/H3N2 (EC50 > 12.5 µg/ml, SI < 1.03), respectively. Antimicrobial peptides LL-37 and HD-5, IL-6 and TNF-α produced by oral keratinocytes were significantly induced by the film spray, while hBD2 was significantly reduced.

Conclusion

Film spray containing curcumin possesses multiple actions against SARS-CoV-2 infection by inhibiting ACE-2 binding in target cells and enhancing mucosal innate immunity. The film spray can also inhibit influenza virus infection. Therefore, the curcumin film spray may be effective in preventing the viral infection of both SARS-CoV-2 and influenza.
