ABSTRACT

BACKGROUND: Although hepatitis B is vaccine-preventable, it remains a significant health problem. To the best of our knowledge, this is the first hepatitis B outbreak report from Türkiye.

AIMS: To investigate the cause of hepatitis B outbreak in a nursing home for the disabled and make recommendations for prevention.

METHODS: An outbreak of acute hepatitis B was declared in a nursing home for the disabled following the admission of 3 patients from the home in a hospital. Collaborative response was initiated with the Provincial Health Directorate through the Public Health Infectious Diseases Department. We began tracking the infection and monitoring active cases. Audits and controls were carried out to determine the source, establish protection and control measures, and prevent further transmission.

RESULTS: Six of the 65 nursing home residents were diagnosed with acute hepatitis B. Four of them had diabetes and their blood glucose levels were monitored for at least 12 months. Two of the patients had received dental treatment in the last 6 months. The frequency of both variables, which may be an indication of the transmission route, was statistically significantly greater in the acute hepatitis B group. All the patients who could be sequenced were identified as genotype D. While 3 patients recovered fully, 2 were diagnosed with chronic hepatitis B and one died due to fulminant hepatitis.

CONCLUSION: Standard routine immunization should be implemented as a preventive measure for acute hepatitis B. Frequent supervision and training on hygiene practices and safety precautions should be conducted for care staff working in collective residential facilities.

ABSTRACT

BACKGROUND: The mental health of students plays a crucial role in their learning and performance. The COVID-19 pandemic, the political turmoil and a coup in Sudan has exacerbated stress and anxiety among university students in Sudan due to uncertainty about their academic activities.

AIM: To assess post-traumatic stress disorder (PTSD) occurrence and coping strategies adopted by university students in Sudan.

METHODS: This cross-sectional survey was conducted from March to June 2022. It used the Coping Orientation to Problems Experienced (Brief-COPE) and Impact of Event Scale-Revised (IES-R) questionnaires to assess the occurrence of PTSD and coping strategies among 596 university students in Sudan. Descriptive statistics were used to determine the frequency and percentage, Student’s t test was used to compare the means of 2 groups and one-way analysis of variance to compare the means of ≥ 3 groups.

RESULTS: There was a high prevalence of PTSD among the students, with a score of 31.2 (SD 16.4). The total score of PTSD was higher among female students. Around 36% of the students had a PTSD score > 37, which is considered high enough to suppress immune function. The most widely adopted coping strategies were religion and acceptance of the situation, while substance use was the least. Students who had COVID-19 infection during the pandemic differed significantly from uninfected students in the application of coping strategies. In contrast, students whose family members or friends had COVID-19 were not significantly different from students with uninfected family members or friends in the application of the coping strategies, such as self-blame, denial, substance use, and behavioural disengagement.

CONCLUSION: We recommend the initiation and implementation of psychological counselling programmes for university students in Sudan onsite or remotely. Further research should be carried out to assess the long-term effects of the pandemic and the political conflicts so as to design and implement appropriate and efficient interventions.

ABSTRACT

BACKGROUND: One of the keys to preventing a re-emergence of the COVID-19 pandemic is the attainment and maintenance of high vaccination coverage in urban and rural areas.

AIMS: To estimate the coverage of COVID-19 vaccination in a rural population and identify the determinants of vaccination.

METHODOLOGY: A cross-sectional survey was conducted in April 2023 in 5 rural districts of Sindh Province, Pakistan. From each district, 30 clusters (villages) were randomly selected, and 7 households were randomly sampled from each cluster using the 30/7 technique. Household members above 12 years of age were included. Vaccination status was categorized as non-vaccinated, partially vaccinated (either with 1 dose or without booster) and completely vaccinated (2 doses with 1 booster). Adjusted odds ratios with 95% confidence intervals using multinomial logistic regression were computed to determine the factors associated with partial and complete vaccination. Data was analysed using SPSS version 20.

RESULTS: Among the 3545 individuals surveyed across 1050 households, 25.9% were not vaccinated, 55.0% were partially vaccinated, and 19.1% were fully vaccinated. Younger age, lack of formal education and residing in flood-affected districts were significantly negatively associated with being vaccinated, while living at <5 km from a vaccination facility was significantly positively associated with partial and complete vaccination. Residents of Dadu (OR=0.03, 95% CI=0.01-0.04), Jamshoro (OR=0.05, 95% CI=0.03-0.08), Hyderabad (OR=0.03, 95% CI=0.02-0.05), and Tando Allahyar (OR=0.09, 95% CI=0.05-0.15) districts were significantly less likely to be completely vaccinated than those in Tharparkar. The most common reasons for not being vaccinated were, the perception that COVID-19 is mild (34.5%), fear of side-effects (22.7%), unavailability of the vaccine (19.8%), and fear of acquiring COVID-19 infection through the vaccine (15.8%).

CONCLUSION: Vaccination coverage was low in some of the districts, particularly the flood-affected districts, mainly due to certain myths. There is a need for community outreaches to debunk myths about COVID-19 vaccination among these rural populations.

ABSTRACT

BACKGROUND: Violence against children constitutes a significant public health problem globally.

AIM: To document and compare media reports of violence against children before and during COVID-19, and measures taken by countries to address such violence.

METHODS: This comparative review covered news reports of violence against children from 1 January to 30 June of 2019 and 2020 in the WHO Eastern Mediterranean Region countries. A total of 823 articles published in Arabic and English, covering incidents, initiatives, opinions and views on all types of violence among children under 18 years of age were sourced using search engines and platforms and reviewed. News on incidents was analysed quantitatively while news on initiatives and opinions was analysed qualitatively.

RESULTS: Some 40.3% of the news reports was on incidents, followed by interviews or opinions (31.5%) and initiatives (28.2%). There were 1129 reports of violence against children from 1 January to 30 June of 2019 and 1880 for the same period in 2020. Reports of physical violence increased from 34% in 2019 to 40% in 2020, while reports of sexual violence decreased from 45% in 2019 to 37% in 2020. Views and opinion reports showed 0.4-1.1% alignment with the 7 INSPIRE strategies.

CONCLUSION: The COVID-19 pandemic affected the incidence and reporting of violence against children across the region. It is essential to provide accurate and sensitive media coverage for incidences of violence against children so that survivors and at-risk children can receive adequate support and ensure that communities can tackle it appropriately.

ABSTRACT

BACKGROUND: The transcription factor SALL4 is associated with embryonic pluripotency and has proposed as a novel immunohistochemistry (IHC) marker for diagnosing germ cell tumors. SALL4 comprises three isoforms, and SALL4-A being the full-length isoform. Studying its isoforms could revolutionize testicular cancer prognosis and subtype differentiation.

METHODS: The expression and clinical significance of isoform “A” of SALL4 was evaluated in 124 testicular germ cell tumors (TGCTs) subtypes, adjacent normal tissues and 22 benign tumors, using immunohistochemistry on tissue microarrays (TMA).

RESULTS: A statistically significant higher expression of nuclear and cytoplasmic SALL4-A was detected in TGCTs histological subtypes and benign tumors compared to the normal tissues. Seminoma and yolk sac tumors had the highest nuclear and cytoplasmic expression of SALL4-A. A significant correlation was detected between the higher nuclear expression of SALL4-A and increased pT stages (P = 0.026) in seminomas. Whereas in embryonal carcinomas, cytoplasmic expression of SALL4-A was associated with the tumor recurrence (P= 0.04) and invasion of the epididymis (P = 0.011).

CONCLUSIONS: SALL4-A isoform expression in the cytoplasm and nucleus of TGCTs may be associated with histological differentiation. In the seminoma subtype of TGCTs, higher expression of SALL4-A may be used as a predictive indicator of poorer outcomes and prognosis.

ABSTRACT

BACKGROUND: Diffusion kurtosis imaging (DKI) and neurite orientation dispersion and density imaging (NODDI) provide more comprehensive and informative perspective on microstructural alterations of cerebral white matter (WM) than single-shell diffusion tensor imaging (DTI), especially in the detection of crossing fiber. However, studies on systemic lupus erythematosus patients without neuropsychiatric symptoms (non-NPSLE patients) using multi-shell diffusion imaging remain scarce.

METHODS: Totally 49 non-NPSLE patients and 41 age-, sex-, and education-matched healthy controls underwent multi-shell diffusion magnetic resonance imaging. Totally 10 diffusion metrics based on DKI (fractional anisotropy, mean diffusivity, axial diffusivity, radial diffusivity, mean kurtosis, axial kurtosis and radial kurtosis) and NODDI (neurite density index, orientation dispersion index and volume fraction of the isotropic diffusion compartment) were evaluated. Tract-based spatial statistics (TBSS) and atlas-based region-of-interest (ROI) analyses were performed to determine group differences in brain WM microstructure. The associations of multi-shell diffusion metrics with clinical indicators were determined for further investigation.

RESULTS: TBSS analysis revealed reduced FA, AD and RK and increased ODI in the WM of non-NPSLE patients (P < 0.05, family-wise error corrected), and ODI showed the best discriminative ability. Atlas-based ROI analysis found increased ODI values in anterior thalamic radiation (ATR), inferior frontal-occipital fasciculus (IFOF), forceps major (F_major), forceps minor (F_minor) and uncinate fasciculus (UF) in non-NPSLE patients, and the right ATR showed the best discriminative ability. ODI in the F_major was positively correlated to C3.

CONCLUSION: This study suggested that DKI and NODDI metrics can complementarily detect WM abnormalities in non-NPSLE patients and revealed ODI as a more sensitive and specific biomarker than DKI, guiding further understanding of the pathophysiological mechanism of normal-appearing WM injury in SLE.

ABSTRACT

This study characterized adult primary care medical assistant (MA) staffing. National Survey of Healthcare Organizations and Systems (n = 1,252) data were analyzed to examine primary care practice characteristics associated with MA per primary care clinician (PCC) staffing ratios. In 2021, few practices (11.4%) had ratios of 2 or more MAs per PCCs. Compared with system-owned practices, independent (odds ratio [OR] = 1.76, P <0.05) and medical group-owned (OR = 2.09, P <0.05) practices were more likely to have ratios of 2 or more MAs per PCCs, as were practices with organizational cultures oriented to innovation (P <0.05). Most primary care practices do not have adequate MA staffing.

ABSTRACT

PURPOSE: Procedures are manual technical skills clinicians perform for their patients. Family physicians (FPs) acquire these skills during residency; most are undertaken in outpatient settings. We performed a retrospective observational cohort study to describe the extent to which FPs perform the core procedures recommended by the Council of Academic Family Medicine (CAFM) and how this might have changed over time.

METHODS: The CAFM recommended a list of procedures all FP residents should perform competently after graduation. We modified this list for Medicare beneficiaries to enable matching with Current Procedural Terminology codes. We probed Medicare Part B databases for modified CAFM procedure claims submitted by FPs in 2021 and how these claims changed from 2014 to 2021.

RESULTS: In 2021, there were 904,278 modified CAFM procedures filed by 9,410 FPs in the outpatient setting. All procedures were clustered with respect to organ system (eg, musculoskeletal, skin, pulmonary). Beginning in 2014 and continuously through 2021, there was a 33% decrease in outpatient procedures filed and a 36% decrease in the number of FPs filing them.

CONCLUSIONS: Office-based procedures are integral to a primary care physician’s role, although the activity is rarely analyzed. At a time when the Medicare population is growing, the number of available FPs and the number of procedures they perform are not. This decrease might result from the changing scope of FP practice, new referral patterns, task shifting, and/or increased delegation to physician associates and nurse practitioners.

ABSTRACT

There is great variation in the experiences of Latiné/e/x/o/a, Hispanic, and/or Spanish origin (LHS) individuals in the United States, including differences in race, ancestry, colonization histories, and immigration experiences. This essay calls readers to consider the implications of the heterogeneity of lived experiences among LHS populations, including variations in country of origin, immigration histories, time in the United States, languages spoken, and colonization histories on patient care and academia. There is power in unity when advocating for community, social, and political change, especially as it pertains to equity, diversity, and inclusion (EDI; sometimes referred to as DEI) efforts in academic institutions. Yet, there is also a critical need to disaggregate the LHS diaspora and its conceptualization based on differing experiences so that we may improve our understanding of the sociopolitical attributes that impact health. We propose strategies to improve recognition of these differences and their potential health outcomes toward a goal of health equity.

ABSTRACT

PURPOSE: The COVID-19 pandemic abruptly interrupted breast cancer screening, an essential preventive service in primary care. We aimed to evaluate the pandemic’s impact on overall and follow-up breast cancer screening using real-world health records data.

METHODS: We retrospectively analyzed a cohort of women eligible for breast cancer screening through the study period from January 1, 2017 to February 28, 2022 using TriNetX Research Network data. We examined the temporal trend of monthly screening volume throughout the study period and compared the rate of adherence to follow-up screening within 24 months after the previous screening when the follow-up screening was due in the pre-COVID period vs the COVID period. To account for multiple screenings in the longitudinal data, we applied a logistic regression model using generalized estimating equations with adjustment for individual-level covariates.

RESULTS: Among 1,186,669 screening-eligible women, the monthly screening volume temporarily decreased by 80.6% from February to April 2020 and then rebounded to close to pre-COVID levels by June 2020. Yet, the follow-up screening rate decreased from 78.9% (95% CI, 78.8%-79.0%) in the pre-COVID period to 77.7% (95% CI, 77.6%-77.8%) in the COVID period. Multivariate regression analysis also showed a lower adherence to follow-up screening during the COVID period (odds ratio = 0.86; 0.86-0.87) and a greater pandemic impact among women aged 65 years and older and women of non-Hispanic “other” race (Asian, American Indian or Alaska Native, and Native Hawaiian or Other Pacific Islander).

CONCLUSIONS: The COVID-19 pandemic had a transient negative effect on breast cancer screening overall and a prolonged negative effect on follow-up screening. It also exacerbated gaps in adherence to follow-up screening, especially among certain vulnerable groups, requiring innovative strategies to address potential health disparities in primary care.
