Screening for hepatitis B in the Bronx West African community with a blood pressure cuff: a cohort study

Hepatitis B (HBV) and hypertension (HTN) are prevalent in West Africa (WA). Inadequate control is common, and evaluation and management are challenging among immigrants due to unfamiliarity with the United States (US) healthcare system. While HBV is stigmatised, HTN is recognised as an important condition. We describe how a HTN screening program can facilitate HBV screening in the Bronx WA community. Thirty-minute HTN educational programs were delivered in collaboration with faith-based organisations, and 5-min presentations were presented upon request at community gatherings. Arrangements were made for those interested in a clinic visit where a questionnaire was completed, blood pressure (BP) measured, a free BP cuff provided, HBV testing performed, and referrals made. For those without ongoing care, insurance was arranged, and linkage to care provided. Seven 30-min and five 5-min presentations were conducted. After the 30-min presentation, 204 of 445 attendees (45.8%) requested a visit, and 68 (33.3%) attended the visit. After the 5-min presentation, 80 requested a visit and 51 (63.8%) attended the visit. A BP>140/90mmHg was present in 122 individuals (48.4%), including 43 (17.1%) without a history of HTN and 39 (15.5%) with BP>160/90mmHg. All except two who reported previous testing agreed to HBV testing. 19 (7.5%) were hepatitis B surface antigen positive. Transition into ongoing care was provided for 60 (33.9%) with HTN who were not integrated into the US healthcare system. HTN screening with a free BP cuff promotes HBV screening and US healthcare integration. No funding.

A Portable, Integrated, Sample-In Result-Out Nucleic Acid Diagnostic Device for Rapid and Sensitive Chikungunya Virus Detection.

Chikungunya virus, a mosquito-borne virus that causes epidemics, is often misdiagnosed due to symptom similarities with other arboviruses. Here, a portable and integrated nucleic acid-based diagnostic device, which combines reverse transcription-loop-mediated isothermal amplification and lateral-flow detection, was developed. The device is simple to use, precise, equipment-free, and highly sensitive, enabling rapid chikungunya virus identification. The result can be obtained by the naked eye within 40 min. The assay can effectively distinguish chikungunya virus from dengue virus, Japanese encephalitis virus, Zika virus, and yellow fever virus with high specificity and sensitivity as low as 598.46 copies mL-1. It has many benefits for the community screening and monitoring of chikungunya virus in resource-limited areas because of its effectiveness and simplicity. The platform has great potential for the rapid nucleic acid detection of other viruses.

Feature fusion method for pulmonary tuberculosis patient detection based on cough sound.

Since the COVID-19, cough sounds have been widely used for screening purposes. Intelligent analysis techniques have proven to be effective in detecting respiratory diseases. In 2021, there were up to 10 million TB-infected patients worldwide, with an annual growth rate of 4.5%. Most of the patients were from economically underdeveloped regions and countries. The PPD test, a common screening method in the community, has a sensitivity of as low as 77%. Although IGRA and Xpert MTB/RIF offer high specificity and sensitivity, their cost makes them less accessible. In this study, we proposed a feature fusion model-based cough sound classification method for primary TB screening in communities. Data were collected from hospitals using smart phones, including 230 cough sounds from 70 patients with TB and 226 cough sounds from 74 healthy subjects. We employed Bi-LSTM and Bi-GRU recurrent neural networks to analyze five traditional feature sets including the Mel frequency cepstrum coefficient (MFCC), zero-crossing rate (ZCR), short-time energy, root mean square, and chroma_cens. The incorporation of features extracted from the speech spectrogram by 2D convolution training into the Bi-LSTM model enhanced the classification results. With traditional futures, the best TB patient detection result was achieved with the Bi-LSTM model, with 93.99% accuracy, 93.93% specificity, and 92.39% sensitivity. When combined with a speech spectrogram, the classification results showed 96.33% accuracy, 94.99% specificity, and 98.13% sensitivity. Our findings underscore that traditional features and deep features have good complementarity when fused using Bi LSTM modelling, which outperforms existing PPD detection methods in terms of both efficiency and accuracy.

Community Health Benefits Through a Student-Run Nonprofit Pediatric Wellness Clinic.

Purpose Community screening programs have been in effect since they were utilized in the 19th century at county fairs. A free pediatric health screening program was created by an osteopathic medical school in South Carolina in collaboration with a pediatric dental outreach organization to engage the local underserved community and train community-minded medical professionals. This study sought to demonstrate the efficacy and need for a student-run monthly pediatric health screening program in an underserved pediatric demographic. Methods A retrospective study of preexisting de-identified data obtained from a student-run health screening program was analyzed to determine the efficacy of the screening program in detecting chronic health risk factors in children in an underserved population. Patients were recruited through a partnership with a free dental clinic for underserved and uninsured children. Patients who attended the clinic were offered the opportunity to have a free, comprehensive health assessment following their dental visit. The function of this program was unique in that uninsured, underserved patients were provided free dental care and a free health assessment. Pediatric patients were screened for basic health information such as weight, height, BMI, vision, cardiovascular health, hypertension, asthma (reported via questionnaire by either the parent or child when applicable), nutrition, and lead poisoning (via questionnaire). The program also offered families additional support by connecting them to local resources and answering any questions they had about their children's health. Data from 14 health screening events was collected for quality improvement and efficacy monitoring. Descriptive analyses were performed. Results and analysis The health screening program assessed 124 children between October 2021 and March 2023 over 14 health screening events. The patients ranged from one year old to 26 years old, with a mean age of 9.65 years. Patients were predominantly Hispanic (79.67%). About one-third (27.64%) of children who were screened had positive findings associated with increased risk for chronic disease. Nearly half (43.90%) of families that were screened requested further information on ways to obtain health insurance and regular primary care services (utilized Access Health). Of the one-third of children with positive risk factors, 12.20% reported positive findings associated with asthma. Of the patients with positive risk factors, 8.94% had vision abnormalities, most of whom had not been seen by an ophthalmologist. This preliminary analysis will be followed by a secondary analysis that further investigates patient demographics (primarily Hispanic) as well as age distribution across various risk factors. Conclusion This pediatric health screening program has demonstrated a basic level of efficacy by successfully identifying increased risk for chronic disease in the underserved pediatric population. The need for these screening events was highlighted by the identification of untreated positive findings.

Participatory action research to develop and implement multicomponent, multilevel strategies for implementing colorectal cancer screening interventions in American Indian communities in New Mexico

BackgroundDespite the effectiveness of colorectal cancer (CRC) screening, American Indians (AIs) have low screening rates in the US. Many AIs receive care at Indian Health Services, Tribal, and Urban Indian (I/T/U) healthcare facilities, where published evidence regarding the implementation of CRC screening interventions is lacking. To address this gap, the University of New Mexico Comprehensive Cancer Center and the Albuquerque Area Southwest Tribal Epidemiology Center collaborated with two tribally-operated healthcare facilities in New Mexico with the goal of improving CRC screening rates among New Mexico’s AI communities.MethodsGuided by the principles of Community Based Participatory Research, we engaged providers from the two tribal healthcare facilities and tribal community members through focus group (two focus groups with providers (n = 15) and four focus group and listening sessions with community members (n = 65)), to elicit perspectives on the feasibility and appropriateness of implementing The Guide to Community Preventive Services (The Community Guide) recommended evidence-based interventions (EBIs) and strategies for increasing CRC screening. Within each tribal healthcare facility, we engaged a Multisector Action Team (MAT) that participated in an implementation survey to document the extent to which their healthcare facilities were implementing EBIs and strategies, and an organizational readiness survey that queried whether their healthcare facilities could implement additional strategies to improve uptake of CRC screening.ResultsThe Community Guide recommended EBIs and strategies that received the most support as feasible and appropriate from community members included: one-on-one education from providers, reminders, small media, and interventions that reduced structural barriers. From the providers’ perspective, feasible and acceptable strategies included one-on-one education, patient and provider reminders, and provider assessment and feedback. Universally, providers mentioned the need for patient navigators who could provide culturally appropriate education about CRC and assist with transportation, and improved support for coordinating clinical follow-up after screening. The readiness survey highlighted overall readiness of the tribal facility, while the implementation survey highlighted that few strategies were being implemented.ConclusionsFindings from this study contribute to the limited literature around implementation research at tribal healthcare facilities and informed the selection of specific implementation strategies to promote the uptake of CRC screening in AI communities.

Protein Intake and Physical Activity Levels as Determinants of Sarcopenia Risk in Community-Dwelling Older Adults.

Community screening for sarcopenia is complex, with barriers including access to specialized equipment and trained staff to conduct body composition, strength and function assessment. In the current study, self-reported dietary protein intake and physical activity (PA) in adults ≥65 years was assessed relative to sarcopenia risk, as determined by body composition, strength and physical function assessments, consistent with the European Working Group on Sarcopenia in Older People (EWGSOP) definition. Of those screened (n = 632), 92 participants (77% female) were assessed as being at high risk of developing sarcopenia on the basis of dietary protein intake ≤1 g∙kg-1∙day-1 [0.9 (0.7-0.9) g∙kg-1∙day-1] and moderate intensity physical activity <150 min.week-1. A further 31 participants (65% female) were defined as being at low risk, with both protein intake [1.2 (1.1-1.5) g∙kg-1∙day-1] and PA greater than the cut-off values. High-risk participants had reduced % lean mass [53.5 (7.8)% versus 54.8 (6.1)%, p < 0.001] and impaired strength and physical function. Notably, high-risk females exhibited greater deficits in lean mass and strength, with minimal differences between groups for males. In community-dwelling older adults, self-reported low protein intake and low weekly PA is associated with heightened risk for sarcopenia, particularly in older women. Future research should determine whether early intervention in older adults with low protein intake and PA attenuates functional decline.

Evidence-Based Strategies for Injury Prevention and Exercise Prescription in Elderly Communities: The Physical Therapist's Perspective

Injury prevention and exercise prescription are critical components of healthcare for older adults. Physical therapists play a critical role in fall risk screening, assessment, and prevention in elderly communities. By incorporating STEADI (Stopping Elderly Accidents, Deaths, and Injuries) and other evidence-based tools and resources, physical therapists can help identify and address fall risk factors, link older adults with community-based programs and resources, and reduce the incidence of falls and related injuries in this population. Evidence-based interventions for fall prevention include exercise interventions that are tailored and include a combination of exercise types, considering individual abilities and preferences. Exercise programs can reduce falls in older people living in residential aged care facilities, but exercise has little or no lasting effect on falls after the end of a program. Physical therapists should consider the patient's fall risk, functional limitations, and comorbidities when prescribing exercises for balance and falls prevention. Physical therapists can help elderly communities implement evidence-based strategies for injury prevention and exercise prescription by adopting a person-centered approach, challenging ageist stereotypes, using sound outcome measures, prioritizing physical activity, and collaborating with other healthcare professionals. By doing so, physical therapists can promote the health, independence, and well-being of older adults, and help them lead active, fulfilling lives. A combination of strength, balance, and functional training exercises, as well as other evidence-based strategies, can significantly reduce the risk of falls in elderly communities. Physical therapists and healthcare providers should consider these interventions when developing fall prevention programs for older adults. Exercise interventions for preventing falls in elderly communities should be implemented regularly, with a frequency of at least three sessions per week, and for a duration of up to 12 months.

Community screening for dementia among older adults in China: a machine learning-based strategy

BackgroundDementia is a leading cause of disability in people older than 65 years worldwide. However, diagnosing dementia in its earliest symptomatic stages remains challenging. This study combined specific questions from the AD8 scale with comprehensive health-related characteristics, and used machine learning (ML) to construct diagnostic models of cognitive impairment (CI).MethodsThe study was based on the Shenzhen Healthy Ageing Research (SHARE) project, and we recruited 823 participants aged 65 years and older, who completed a comprehensive health assessment and cognitive function assessments. Permutation importance was used to select features. Five ML models using BalanceCascade were applied to predict CI: a support vector machine (SVM), multilayer perceptron (MLP), AdaBoost, gradient boosting decision tree (GBDT), and logistic regression (LR). An AD8 score ≥ 2 was used to define CI as a baseline. SHapley Additive exPlanations (SHAP) values were used to interpret the results of ML models.ResultsThe first and sixth items of AD8, platelets, waist circumference, body mass index, carcinoembryonic antigens, age, serum uric acid, white blood cells, abnormal electrocardiogram, heart rate, and sex were selected as predictive features. Compared to the baseline (AUC = 0.65), the MLP showed the highest performance (AUC: 0.83 ± 0.04), followed by AdaBoost (AUC: 0.80 ± 0.04), SVM (AUC: 0.78 ± 0.04), GBDT (0.76 ± 0.04). Furthermore, the accuracy, sensitivity and specificity of four ML models were higher than the baseline. SHAP summary plots based on MLP showed the most influential feature on model decision for positive CI prediction was female sex, followed by older age and lower waist circumference.ConclusionsThe diagnostic models of CI applying ML, especially the MLP, were substantially more effective than the traditional AD8 scale with a score of ≥ 2 points. Our findings may provide new ideas for community dementia screening and to promote such screening while minimizing medical and health resources.

RETFound-enhanced community-based fundus disease screening: real-world evidence and decision curve analysis.

Visual impairments and blindness are major public health concerns globally. Effective eye disease screening aided by artificial intelligence (AI) is a promising countermeasure, although it is challenged by practical constraints such as poor image quality in community screening. The recently developed ophthalmic foundation model RETFound has shown higher accuracy in retinal image recognition tasks. This study developed an RETFound-enhanced deep learning (DL) model for multiple-eye disease screening using real-world images from community screenings. Our results revealed that our DL model improved the sensitivity and specificity by over 15% compared with commercial models. Our model also shows better generalisation ability than AI models developed using traditional processes. Additionally, decision curve analysis underscores the higher net benefit of employing our model in both urban and rural settings in China. These findings indicate that the RETFound-enhanced DL model can achieve a higher net benefit in community-based screening, advocating its adoption in low- and middle-income countries to address global eye health challenges.

Understanding of cervical cancer, acceptability of HPV self-collection, and prevalence of HPV in a semi-urban setting in Bangladesh.

Human Papillomavirus (HPV) self-sampling has been implemented successfully as an alternative to traditional forms of cervical cancer screening in low-resource settings. Through Bangladesh's current national cervical cancer screening program, only about 10% of the at-risk population is reached. Thus, Bangladesh is an ideal setting to consider HPV self-sampling to improve cervical cancer prevention efforts. However, the feasibility and acceptability of HPV self-sampling has not been evaluated in Bangladesh. We aimed to understand levels of HPV and cervical cancer knowledge and to evaluate the feasibility and acceptability of HPV self-sampling for cervical cancer screening in a semi-urban Bangladeshi community. Participants were recruited from a local clinic; 164 women completed a cross-sectional questionnaire about attitudes towards screening, and cervical cancer and HPV risk factor knowledge, and provided self-collected cervical samples for high-risk HPV testing. Of the participants, 4.3% tested positive for high-risk HPV and were referred for appropriate follow-up care. Nearly all participants had heard of cervical cancer, though specific knowledge was quite low. Self-sampling for high-risk HPV testing had high rates of acceptability, high rates of convenience, and very little discomfort and embarrassment reported in this study population, making implementing HPV self-sampling as a form of cervical cancer screening in Bangladesh appear feasible.

A pilot cross-sectional study of non-communicable diseases in TB household contacts.

Data on the prevalence of non-communicable diseases (NCDs) in TB household contacts (HHCs) are limited, yet important to inform integrated screening and care for NCD within contact investigations. It is also unclear if screening these contacts reveals more people with NCDs than individuals in the same neighbourhood. We conducted a pilot cross-sectional study in South Africa and Tanzania, enrolling adult HHCs of TB and individuals in neighbourhood households (controls). We inquired about known NCD and systematically measured blood pressure, and tested for spot blood glucose and haemoglobin A1c. We enrolled 203 adult contacts of 111 persons with TB and 160 controls. Among contacts, respectively 12.2% (95% CI 8.3-17.6) and 39.7% (95% CI 33.1-46.7) had diabetes and hypertension, compared to 14.1% (95% CI 9.2-21.0) and 44.7% (95% CI 36.9-52.7) among controls. More than half of NCDs were newly identified. We did not find a significant difference in the prevalence of at least one NCD between the two groups (OR 0.85, 95% CI 0.50-1.45, adjusted for age and sex). We found a high prevalence of undiagnosed NCDs among contacts, suggesting a potential benefit of integrating NCD screening and care within contact investigations. Screening in the same community might similarly find undiagnosed NCDs.

The prevalence of depression, determinants, and linkage with functional disability amongst postmenopausal women in India: Evidence from the Longitudinal Ageing Study in India

BackgroundThe study objective was estimating the prevalence and determinants of depression amongst postmenopausal women in India. Additionally, we used panel mediation analysis to model the extent to which multimorbidity was associated with depression after adjusting for the effects of functional disability in the participants. MethodsData from 28,160 women aged 50 and above from the Longitudinal Aging Study in India (LASI) Wave 1 were analyzed. Depression was assessed using the Composite International Diagnostic Interview-Short Form (CIDI-SF), with multimorbidity and functional disability (ADL and IADL) considered as key predictor variables. Logistic regression and Karlson-Holm-Breen (KHB) mediation analysis were employed. ResultsThe weighted prevalence of depression among women aged ≥ 50 years was 21.76% (95% CI: 20.81, 22.73), significantly higher women aged < 50 years (17.60%, 95% CI: 16.33, 18.94). Factors independently associated with increased odds of depression included being unmarried, rural residence, and multimorbidity, while higher educational status was associated with lower odds of depression. The relationship between multimorbidity and depression was partially mediated by ADL and IADL disabilities. Notable regional (state) variations in the magnitude of depression were observed. ConclusionsNearly one in five postmenopausal women in India aged 50 years and older have clinical depression. Community screening for reaching the unreached with primary care mental health strengthening need enhanced policy focus.

Decomposing and simplifying the Fracture Risk Assessment Tool-a module from the Taiwan-specific calculator.

The Fracture Risk Assessment Tool (FRAX®) is a widely utilized country-specific calculator for identifying individuals with high fracture risk; its score is calculated from 12 variables, but its formulation is not publicly disclosed. We aimed to decompose and simplify the FRAX® by utilizing a nationwide community survey database as a reference module for creating a local assessment tool for osteoporotic fracture community screening in any country. Participants (n = 16384; predominantly women (75%); mean age = 64.8years) were enrolled from the Taiwan OsteoPorosis Survey, a nationwide cross-sectional community survey collected from 2008 to 2011. We identified 11 clinical risk factors from the health questionnaires. BMD was assessed via dual-energy X-ray absorptiometry in a mobile DXA vehicle, and 10-year fracture risk scores, including major osteoporotic fracture (MOF) and hip fracture (HF) risk scores, were calculated using the FRAX®. The mean femoral neck BMD was 0.7 ± 0.1g/cm2, the T-score was -1.9 ± 1.2, the MOF was 8.9 ± 7.1%, and the HF was 3.2 ± 4.7%. Following FRAX® decomposition with multiple linear regression, the adjusted R2 values were 0.9206 for MOF and 0.9376 for HF when BMD was included and 0.9538 for MOF and 0.9554 for HF when BMD was excluded. The FRAX® demonstrated better prediction for women and younger individuals than for men and elderly individuals after sex and age stratification analysis. Excluding femoral neck BMD, age, sex, and previous fractures emerged as 3 primary clinical risk factors for simplified FRAX® according to the decision tree analysis in this study population. The adjusted R2 values for the simplified country-specific FRAX® incorporating 3 premier clinical risk factors were 0.8210 for MOF and 0.8528 for HF. After decomposition, the newly simplified module provides a straightforward formulation for estimating 10-year fracture risk, even without femoral neck BMD, making it suitable for community or clinical osteoporotic fracture risk screening.

High Prevalence of Familial Hypercholesterolemia Due to the Founder Effect of the LDLR c.2271del Variant in Communities of Oaxaca, Mexico

In Mexico, familial hypercholesterolemia (FH) is underdiagnosed, but population screening in small communities where at least one homozygous patient has already been detected results in a useful and inexpensive approach to reduce this problem. Considering that we previously reported nine homozygous cases from the state of Oaxaca, we decided to perform a population screening to identify patients with FH and to describe both their biochemical and genetic characteristics. LDL cholesterol (LDLc) was quantified in 2,093 individuals from 11 communities in Oaxaca; either adults with LDLc levels ≥170 mg/dL or children with LDLc ≥130 mg/dL were classified as suggestive of FH and therefore included in the genetic study. LDLR and APOB (547bp fragment of exon 26) genes were screened by sequencing and MLPA analysis. Two hundred and five individuals had suggestive FH, with a mean LDLc of 223 ± 54 mg/dL (range: 131-383 mg/dL). Two pathogenic variants in the LDLR gene were detected in 149 individuals: c.-139_-130del (n = 1) and c.2271del (n = 148). All patients had a heterozygous genotype. With the cascade screening of their relatives (n = 177), 15 heterozygous individuals for the c.2271del variant were identified, presenting a mean LDLc of 133 ± 35 mg/dL (range: 60-168 mg/dL). The FH frequency in this study was 7.8% (164/2093), the highest reported worldwide. A founder effect combined with inbreeding could be responsible for the high percentage of patients with the LDLR c.2271del variant (99.4%), which allowed us to detect both significant biochemical heterogeneity and incomplete penetrance; hence, we assumed the presence of phenotype-modifying variants.

Dementia Screening in Rural Kenya: The Prevalence and Impact of Screening Positive for Dementia

Introduction: In Kenya, there is a lack of data on the number of people with dementia. In this article, we aim to estimate the number of community-dwelling older adults (aged 60 years and above) that are potentially living with dementia in rural Kenya. Methods: Recruitment of older adults occurred through adopting a convenience approach based on the catchment areas served by ten trained community health workers. Screening was conducted using the Brief Community Screening Instrument for Dementia (CSI-D), in which prevalence ratios were reported. Regression analyses were run to understand the association between screening outcome and wellbeing, social isolation, and employment status (adjusted for age, sex, literacy, geography, and social status). Results: Of the 3,546 older adults who were screened for dementia, 652 screened positive (PR = 0.18, 95% CIs: 0.17–0.20). Back estimating screen positives based on established sensitivity and specificity of the tool against a gold standard (clinical diagnosis), yielded a prevalence of 9.4% (0.09, 95% CIs: 0.08–0.11). Screening positive for dementia was associated with poorer quality of life (B = −0.17, p < 0.001) and loneliness (B = 0.28, p < 0.001). Conclusion: There are potentially 258,000 older adults living with dementia in Kenya, who likely have poorer outcomes. We need to encourage a timely diagnosis and develop better ways to support people living with dementia in Kenya and other resource-limited settings.

Prevalence of subclinical pulmonary tuberculosis in adults in community settings: an individual participant data meta-analysis

Subclinical pulmonary tuberculosis, which presents without recognisable symptoms, is frequently detected in community screening. However, the disease category is poorly clinically defined. We explored the prevalence of subclinical pulmonary tuberculosis according to different case definitions. We did a one-stage individual participant data meta-analysis of nationally representative surveys that were conducted in countries with high incidence of tuberculosis between 2007 and 2020, that reported the prevalence of pulmonary tuberculosis based on chest x-ray and symptom screening in participants aged 15 years and older. Screening and diagnostic criteria were standardised across the surveys, and tuberculosis was defined by positive Mycobacterium tuberculosis sputum culture. We estimated proportions of subclinical tuberculosis for three case definitions: no persistent cough (ie, duration ≥2 weeks), no cough at all, and no symptoms (ie, absence of cough, fever, chest pain, night sweats, and weight loss), both unadjusted and adjusted for false-negative chest x-rays and uninterpretable culture results. We identified 34 surveys, of which 31 were eligible. Individual participant data were obtained and included for 12 surveys (620 682 participants) across eight countries in Africa and four in Asia. Data on 602 863 participants were analysed, of whom 1944 had tuberculosis. The unadjusted proportion of subclinical tuberculosis was 59·1% (n=1149/1944; 95% CI 55·8-62·3) for no persistent cough and 39·8% (773/1944; 36·6-43·0) for no cough of any duration. The adjusted proportions were 82·8% (95% CI 78·6-86·6) for no persistent cough and 62·5% (56·6-68·7) for no cough at all. In a subset of four surveys, the proportion of participants with tuberculosis but without any symptoms was 20·3% (n=111/547; 95% CI 15·5-25·1) before adjustment and 27·7% (95% CI 21·0-36·4) after adjustment. Tuberculosis without cough, irrespective of its duration, was more frequent among women (no persistent cough: adjusted odds ratio 0·79, 95% CI 0·63-0·97; no cough: adjusted odds ratio 0·76, 95% CI 0·62-0·93). Among participants with tuberculosis, 29·1% (95% CI 25·2-33·3) of those without persistent cough and 23·1% (18·8-27·4) of those without any cough had positive smear examinations. The majority of people in the community who have pulmonary tuberculosis do not report cough, a quarter report no tuberculosis-suggestive symptoms at all, and a quarter of those not reporting any cough have positive sputum smears, suggesting infectiousness. In high-incidence settings, subclinical tuberculosis could contribute considerably to the tuberculosis burden and to Mycobacterium tuberculosis transmission. Mr Willem Bakhuys Roozeboom Foundation.

Determinants of HIV late presentation among men who have sex with men in Portugal (2014-2019): who's being left behind?

HIV late presentation (LP) remains excessive in Europe. We aimed to analyze the factors associated with late presentation in the MSM population newly diagnosed with HIV in Portugal between 2014 and 2019. We included 391 newly HIV-1 diagnosed Men who have Sex with Men (MSM), from the BESTHOPE project, in 17 countrywide Portuguese hospitals. The data included clinical and socio-behavioral questionnaires and the viral genomic sequence obtained in the drug resistance test before starting antiretrovirals (ARVs). HIV-1 subtypes and epidemiological surveillance mutations were determined using different bioinformatics tools. Logistic regression was used to estimate the association between predictor variables and late presentation (LP). The median age was 31 years, 51% had a current income between 501-1,000 euros, 28% were migrants. 21% had never been tested for HIV before diagnosis, with 42.3% of MSM presenting LP. 60% were infected with subtype B strains. In the multivariate regression, increased age at diagnosis, higher income, lower frequency of screening, STI ever diagnosed and higher viral load were associated with LP. Our study suggests that specific subgroups of the MSM population, such older MSM, with higher income and lower HIV testing frequency, are not being targeted by community and clinical screening services. Overall, targeted public health measures should be strengthened toward these subgroups, through strengthened primary care testing, expanded access to PrEP, information and promotion of HIV self-testing and more inclusive and accessible health services.

Delay in seeking treatment and associated factors among pulmonary tuberculosis patients attending public health facilities in the Metekel zone, Benishangul Gumuz region, Western Ethiopia.

Tuberculosis is a major global public health problem and a leading cause of morbidity and mortality in Ethiopia. TB prevention and control in low-income countries, such as Ethiopia, face significant challenges, including late detection and treatment initiation. A delay in the initiation of tuberculosis treatment increases the morbidity and mortality of patients and community transmission. Therefore, this study aimed to assess patient delay and associated factors among pulmonary tuberculosis patients attending public health facilities in the Metekel Zone, Benishangul Gumuz Region, Western Ethiopia. An institution-based cross-sectional study was conducted from March to August 2020 among newly diagnosed pulmonary tuberculosis patients. All pulmonary tuberculosis patients (416) who came to all public health facilities of the Metekel zone for treatment during the period were included. Data were collected through face-to-face interviews using a structured and pretested questionnaire. A multivariable logistic regression was fitted to identify independent factors for delay in seeking treatment among PTB patients. Adjusted odds ratios with 95% CIs were determined, and variables with p values <0.05 were considered statistically significant. Nearly three-fourths 302 (72.6, 95% CI: 68.5, 76.7) of the patients were delayed in seeking medical advice, with a median patient delay of 27 days (IQR: 21-31). Age of the patients [above 54 years (AOR = 2.65, 95% CI: 1.30, 5.40), 36-54 years (AOR = 1.86, 95% CI: 1.14,3.02)], family size of 5 members and above (AOR = 1.62, 95% CI: 1.10-3.14), travel time above 60 min (AOR = 3.65, 95% CI: 1.55, 8.60), history of visits to informal care providers (AOR = 1.74, 95% CI: 1.11, 3.14), and poor knowledge about PTB (AOR = 1.64, 95% CI: 1.04-2.44) were statistically significant factors associated with delays in seeking treatment among PTB patients. Most pulmonary tuberculosis patients delay seeking medical advice for their illnesses. Delays in seeking treatment were associated with older age, large household size, longer travel time to reach the nearby health facility, visiting informal care providers, and poor knowledge about pulmonary tuberculosis. Hence, it is crucial to consider community screening programs, enhance public awareness, and ensure the accessibility of TB diagnostic and treatment services.

Pemberdayaan Kader Posyandu Upaya Deteksi Dini Komplikasi Kehamilan Penggunakan Community Screening Card Pada Ibu Hamil di Desa Penfui Timur Kabupaten Kupang

One of the causes of maternal mortality is undetected high-risk pregnancies. Since the Covid-19 pandemic, motherhood classes in Kupang Regency have been postponed. By carrying out routine and regular Antenatal Care (ANC) through examination of the condition of the mother and fetus, you can detect any risks that may arise during pregnancy. So that pregnancy complications can be recognized by cadres and pregnant women, it is necessary to train cadres in self-screening for pregnancy complications. One effort that can be done is by using a Community Screening Card. The aim of this activity is to empower posyandu cadres in carrying out early pregnancy detection using the Community Screening Card.
