Individualized prediction of critical illness in older adults: Validation of an elders risk assessment model.

The electronic health record (EHR) presents new opportunities for the timely identification of patients at high risk of critical illness and the implementation of preventive strategies. This study aims to externally validate an EHR-based Elders Risk Assessment (ERA) score to identify older patients at high risk of future critical illness during a primary care visit. This historical cohort study included patients aged ≥65 years who had primary care visits at Mayo Clinic Rochester, MN, between July 2019 and December 2021. The ERA score at the time of the primary care visit was used to predict critical illness, defined as death or ICU admission within 1 year of the visit. A total of 12,885 patients were included in the analysis. The median age at the time of the primary care visit was 75 years, with 44.6% being male. 93.7% of participants were White, and 64.2% were married. The median (25th, 75th percentile) ERA score was 4 (0, 9). 11.3% of study participants were admitted to the ICU or died within 1 year of the visit. The ERA score predicted critical illness within 1 year of a primary care visit with an area under the receiver operating characteristic curve of 0.84 (95% CI 0.83-0.85), which indicates good discrimination. An ERA score of 9 was identified as optimal for implementing and testing potential preventive strategies, with the odds ratio of having the primary outcome in patients with ERA score ≥9 being 11.33 (95%CI 9.98-12.87). This simple EHR-based risk assessment model can predict critical illness within 1 year of primary care visits in older patients. The findings of this study can serve as a basis for testing and implementation of preventive strategies to promote the well-being of older adults at risk of critical illness and its consequences.

Unraveling The Complexity of Urban Vulnerability: Challenges And Strategies In Addressing Social Urban Problem In South Sulawesi

Street children, homeless individuals, and beggars are intricate societal issues that predominantly manifest in urban regions, especially the urban areas of South Sulawesi. The South Sulawesi Provincial Government and the district/city governments in urban areas have implemented policies to address the issue of street children, homeless individuals, and beggars. However, these policies have not been effectively implemented and have not had a significant impact on addressing the problem in urban areas of South Sulawesi. The provincial and district/city administrations in South Sulawesi have four problems in addressing this social issue: family dysfunction, program limits, community involvement, and limited institutional capability. In South Sulawesi, the provincial and district/city administrations in metropolitan areas oversee inter-regional coordination plans and implement preventive, curative, and rehabilitative program strategies to address the issue of street children, beggars, and homeless individuals.

Development and Evaluation of a Serious Game on Pressure Injury Prevention for the Training of Patient Relatives: A Quasi-Experimental Study

Background In recent years, serious games have been used as an educational method in various fields such as economy, marketing, military, education, and health as a training method. Pressure injuries (PIs) are a significant health problem and clinical quality improvement issue throughout the world. Implementation of prevention strategies has gained importance in all healthcare settings due to the negative effects of PIs. Educating patient relatives on PI prevention is essential. Aims This study aimed to develop a serious game for the training of patient relatives on PI prevention and evaluate the game in terms of knowledge acquisition and its features. Methods The study was carried out as a single-group quasi-experimental pre-test and post-test design in three stages between August 1, 2020-April 30, 2022. In the first stage educational content, knowledge assessment test, and game evaluation questionnaire were prepared. A web-based serious game (PreSore: Pressure Injury Prevention Game) was developed in the second stage. The participants played the game in the third stage, and data was collected. The study sample consisted of patient relatives (n=55). A knowledge assessment test (pre-test, post-test, and re-test) and a game evaluation questionnaire were administered for the data collection. Results It was determined that there was a significant increase in knowledge scores after the PreSore game implementation ( p < .001). Most of the participants indicated that the information in the game was easy to understand (98.2%), they wanted to share their educational experience with others with the digital game method (96.4%), and they found the game was authentic (94.5%). Conclusions The study revealed that the PreSore game is a method that could be used to train patient relatives on PI prevention. Integrating the PreSore into daily practice in healthcare institutions and conducting prospective studies are recommended.

‘A kindergarten teacher must have 100 eyes and 100 ears!’: Kindergarten teachers' experiences coping with child sexual abuse and problematic sexual behavior

BackgroundChild sexual abuse (CSA) and problematic sexual behavior (PSB) are worldwide phenomena that occur across all ages. Kindergarten teachers' proactive involvement can be crucial to the prevention, disclosure and intervention of CSA and PSB. However, research on their experiences of contending with CSA and PSB remains limited. ObjectiveThis study examines kindergarten teachers' experiences in Israel with the CSA and PSB of their students. Participants and settingSemi-structured interviews were conducted with 31 teachers: 11 secular Jewish, seven religious Jewish, nine Druze Arab, and four Muslim Arab. MethodsA qualitative analysis was conducted using the interview transcripts as data. ResultsThe analysis revealed three themes illustrating teachers' professional transformations regarding their knowledge of these phenomena: 1) initial shock, uncertainty and sense of responsibility when exposed to CSA and PSB due to missing knowledge, 2) implementation of prevention and intervention strategies regarding CSA and PSB, and 3) embracing a social role to disseminate CSA and PSB knowledge. The findings indicated that the majority of the teachers went from overwhelming shock and fear due to a lack of knowledge in coping with CSA and PSB to a sense of responsibility as a community leader. ConclusionsThe fragmentation of the Israeli education system isolates kindergartens, and the lack of training and education for the teachers left them alone when contending with the CSA and PSB of their students. Nevertheless, the participants exhibited remarkable agency and resourcefulness, gaining the necessary knowledge and acting as knowledge agents within their communities.

Non-Tuberculous Mycobacterial isolates from Panama: A retrospective 5-year analysis (2017-2021)

BackgroundThe genus Mycobacterium includes well-known bacteria such as M. tuberculosis causing tuberculosis and M. leprae causing leprosy. Additionally, various species collectively termed non-tuberculous mycobacteria (NTM) can cause infections in humans and animals, affecting individuals across all age groups and health conditions. However, information on NTM infection prevalence in Panama is limited. MethodsThis study conducted a retrospective analysis of clinical records from 2017 to 2021, specifically focusing on patients with NTM isolates. Data were categorized by variables like sex, age, HIV status, and sample source. ResultsAmong the 4430 clinical records analyzed, 698 were linked to patients with NTM isolates. Of these patients, 397 were male, and 301 were female. Most female patients with NTM isolates (n = 190) were aged >45 to 85 years, while most male patients (n = 334) fell in the >25 to 75 years age group. A noteworthy proportion of male patients (n = 65) were aged 25–35 years. A significant age difference between male (median [min-max] = 53 years [3–90]) and female (median [61 years [6–94]) patients was observed (p < 0.001). Regarding HIV status, 77 positive individuals were male, and 19 were female (p < 0.001). Most samples (n = 566) were sputum samples, with additional pulmonary-associated samples such as broncho-alveolar lavage, tracheal secretions, and pleural fluid samples. Among extrapulmonary isolates (n = 48), sources included catheter secretions, intracellular fluids, peritoneal fluid, blood cultures, cerebrospinal fluid, bone marrow samples, and capillary transplant lesions. Specifically, the analysis identified the pathogenic microorganisms responsible for mycobacteriosis in Panama during the specific period 2017–2021, as M. fortuitum (34.4%), M. intracellulare (20.06%), and M. abscessus (13.75%), respectively. ConclusionsThis study highlights the growing public health concern of NTM infections in Panama. The research provides valuable insights into the prevalence and distribution of NTM species in the country, offering a foundation for the development and implementation of effective prevention and control strategies for NTM infections in Panama.

Knowledge, attitudes and behaviours of a sample of Italian paediatricians towards RSV and its preventive strategies: a cross-sectional study

BackgroundRespiratory Syncytial Virus (RSV) infection mainly affects newborns, infants and young children aged < 2 years. Since an RSV vaccine is in the European Medicines Agency’s waitlist validation, nowadays the prevention only includes passive immunization with monoclonal antibodies (mAb). In the present study we aimed at investigating Italian paediatricians’ knowledge, attitudes and behaviours towards RSV and its prevention.MethodsFrom February to May 2023, an anonymous online questionnaire, with answers based on the Likert scale, was administered to a sample of Italian paediatricians’ members of the Italian Society of Paediatrics. Descriptive and inferential statistical analyses were performed using STATA 17.ResultsThe paediatricians who answered the questionnaire were 507, mostly women (70.6%), aged 30–45 (33.1%), employed in hospitals in 66.6% of cases. The 10.8% of respondents reported that RSV is transmitted only among children younger than 2 years of age and 80.33% of participants that school-age children are not at risk of developing severe forms of RSV disease. The 25% of participants thought that active immunization is currently available to prevent RSV infection and 35.7% that does not exist passive immunization to prevent RSV for infants and newborns aged < 2 years. The 97.5% of physicians managed bronchiolitis cases and 65.6% of participants did not prescribe the administration of mAb. Higher age, seniority and RSV knowledge score were found to be associated with having a higher mAb knowledge score (p < 0.001) and having a higher RSV knowledge was associated with a higher mAb knowledge score (p < 0.001). The logistic regression model found that the odds of a positive attitude towards mAB knowledge score increased by over 3 times (OR 3.23, 95% CI [1.41, 7.40], p = 0.006) for being female and the odds of a positive attitude towards mAB knowledge score increased by almost 10 times (OR 9.73, 95% CI [3.06, 30.89], p < 0.001) for a one-unit increase in RSV knowledge score.ConclusionsPaediatricians’ limited knowledge or awareness could represent a barrier to the implementation of preventive strategies against RSV infection. Strategies to improve paediatricians’ education on RSV prevention are, therefore, crucial.

Social factors and age play a significant role in cervical cancer and advanced-stage disease among Danish women

BackgroundFor cervical cancer (CC), the implementation of preventive strategies has the potential to make cervical cancer occurrence and death largely avoidable. To better understand the factors possibly responsible for cervical cancer, we aimed to examine possible differences in age and social parameters as well as screening status between women with low- or high-stage cervical cancer and matched controls.MethodsThrough the Danish Cancer Registry (DCR), women diagnosed with cervical cancer in Denmark between 1987 and 2016 were included. These were age- and residence-matched in a 1:5 ratio with controls from the general female population. The study population was sub grouped into a low-stage subpopulation with women with early-stage cervical cancer and matched controls and a high-stage subpopulation with women with late-stage cervical cancer and matched controls. Age and social parameters were compared within the subpopulations as well as between low- and high-stage cases. For part of the study population, screening attendance was examined to compare differences in adherence.ResultsOverall, we found that the risk of cervical cancer is significantly increased in socially disadvantaged women and not least non-attenders in screening. Interestingly, the high-stage subpopulation was significantly older than the low-stage subpopulation (p < 0.001), and when examining the impact of age further, we found that for cervical cancer cases, the risk of having low-stage disease decreases significantly with increasing age, whereas the risk of having high-stage disease increases significantly with increasing age. In the screening cohort, significantly less cases than controls were attenders in screening with the most pronounced differences seen in the old subpopulation (women aged 50–64 years) and in the high-stage subpopulation (p-values all < 0.001). Interestingly, when examining the risk of CC for attenders and non-attenders, we demonstrated that many social parameters continue to influence the risk of cervical cancer, even in women attending screening.ConclusionsOlder women, socially disadvantaged women, and non-attenders in screening are particularly vulnerable in terms of developing cervical cancer, especially high-stage disease. Therefore, improvements in the participating rate in screening as well as a revision of the current screening guidelines are needed.

The Malaria Burden: A South African Perspective.

Malaria is a deadly disease caused by protozoan pathogens of the Plasmodium parasite. Transmission to humans occurs through the bite of an infected female Anopheles mosquito. According to the World Health Organization (WHO), an estimated 247 million cases of malaria were recorded worldwide in 2021, with approximately 619 000 malaria deaths. The initial signs of malaria can be mild and challenging to diagnose due to the signs and symptoms being similar to those of other illnesses. The malaria burden remains largely concentrated in the WHO sub-Saharan African region and has been recognised as a significant contributor to morbidity and mortality. This review aims to contribute to the existing knowledge on malaria in South Africa, a region within sub-Saharan Africa, focusing on the epidemiology and life cycle of the malaria parasite as well as diagnostic approaches for detecting malaria. In addition, nonpharmacological and pharmacological interventions for treating and preventing malaria infections will also be discussed herein. While there has been a significant reduction in the global burden of this disease, malaria remains a public health issue in South Africa. As such, the implementation of effective preventative measures and strategies, early diagnosis, and appropriate treatment regimens are crucial to reducing the malaria burden in South Africa.

Child Fatality Review.

Understanding why children die is necessary to implement strategies to prevent future deaths and improve the health of any community. Child fatality review teams (CFRTs) have existed since the 1970s and provide a necessary framework to ensure that proper questions are asked about a child's death. CFRTs provide a vital function in a community to ensure that preventable causes of deaths are identified. Pediatricians are necessary members of CFRTs because they provide medical expertise and context around a child's death. All CFRTs should have pediatric physician representation, and results from team meetings should inform public policy at all levels of government. Pediatricians should be supported in their efforts to be present on CFRTs, and they should use data from team meetings to help advocate for implementing prevention strategies.

Evaluation of Medication Errors and Prevention Strategies in a Selected Tertiary Care Hospital

A medication error is defined as a deviation from the physician’s medication order as written on the patient’s chart. Evaluation of medication errors and the implementation of prevention strategies are necessary to ensure patient safety and improve healthcare outcomes. Prospective and observational study was conducted on 218 patients, 50 (22.9%) reported medication error with 56% females and 44% males. Most of the patients included in the study were in the age group between 18 to 65 years (72%). The most common co-morbidity in patients was hypertension (27.94%). In the study, the most common category of harm is Category D (35.29%), followed by Category A (19.6%), Category F (17.64%), Category E (9.8%), Category B (7.84%), Category C (5.88%), and the least common category of harm was Category I (3.92%) based on NCC MERP guidelines. The most specific reported error was wrong dose either strength or frequency (25.84%). Prescription error 34(68%) was the most common type of error reported based on CHCF guidelines. Comparing the wards in which errors were made, (42%) occurred in the female ward. Categorizing the severity of the effect of error found, 38% patient needs monitoring, 20% patient were not harmed, 18% patients required more hospitalization time, 10% patient required treatment, 10% of the patients were not affected, and 4% of the patient died. After implementing the prevention strategies, prescription errors were prevented but other errors (Dose omission, Multi-dose) were reduced from 20% to 10%.

Epidemiology of substance and opium use among adult residents of Tehran; a comprehensive report from Tehran cohort study (TeCS)

BackgroundThe prevalence and burden of substance and opium use have increased worldwide over the past decades. In light of rapid population changes in Tehran, we aimed to evaluate the prevalence of opium and other substance use among adult residents in Tehran, Iran.MethodFrom March 2016 to March 2019, we utilized data from 8 296 participants in the Tehran Cohort Study recruitment phase (TeCS). We calculated the age-sex-weighted prevalence of substance use and the geographic distribution of substance use in Tehran. We also used logistic regression analysis to determine possible determinants of opium use.ResultWe analyzed data from 8 259 eligible participants with complete substance use data and the average age of participants was 53.7 ± 12.75 years. The prevalence of substance use was 5.6% (95% confidence interval [CI]: 4.6- 7.1%). Substance use was more common in males than females (Prevalence: 10.5% [95% CI: 8.6- 12.6%] vs. 0.5% [95% CI: 0.2- 1.2%], respectively). The age-sex weighted prevalence of substance use was 5.4% (95% CI: 4.6-7.1%). Moreover, opium was the most frequently used substance by 95.8% of substance users. Additionally, we found that male gender (Odds ratio [OR]: 12.1, P < 0.001), alcohol intake (OR: 1.3, P = 0.016), and smoking (OR: 8.5, P < 0.001) were independently associated with opium use.ConclusionsWe found that the prevalence of substance use in Tehran was 5.6%, and opium was the most frequently used substance. In addition, male gender, lower levels of education, alcohol, and tobacco consumption are the main risk factors for substance use in Tehran. Healthcare providers and policymakers can utilize our results to implement preventive strategies to minimize substance use in Tehran.

Study of the effects of dietary patterns on glycemic control in community type 2 diabetic mellitus patients

Objective: To understand the impact of diet on glycemic control in community-managed patients with type 2 diabetes mellitus (T2DM) and provide evidence for implementing prevention strategies and measures for diabetes patients. Methods: Eight communities were randomly selected from Changshu and Wuhan in 2015, and T2DM patients managed in the community were selected to conduct questionnaire surveys, physical measurements, and blood glucose testing. Factor analysis was used to obtain dietary patterns. A binary logistic regression model was used to analyze the factors affecting glycemic control. Results: Finally, 1 818 T2DM patients were included, and the control rate of FPG was 57.59% (95%CI: 55.30%-59.86%), and the control rate of 2 h postprandial blood glucose (2 h PBG) was 24.90% (95%CI: 22.93%- 26.91%). Five dietary patterns were obtained by factor analysis: animal food pattern, fruit-aquatic products-potato patterns, vegetable-grain pattern, egg-milk-bean pattern, and oil-salt patterns. No-conditional multivariate logistic regression analysis showed that after adjusting for confounding factors, the reduced probability of FPG control was related to animal food pattern (OR=0.71, 95%CI: 0.52-0.98) and fruit-aquatic products-potato patterns (OR=0.71, 95%CI: 0.51-0.97). The decrease in the 2 h PBG control probability was related to fruit-aquatic products-potato patterns (OR=0.60, 95%CI: 0.40-0.90). The increased probability of FPG and 2 h postprandial glucose control were both related to vegetable-grain pattern (OR=1.41, 95%CI: 1.03-1.94; OR=1.68, 95%CI: 1.13-2.51) and egg-milk-bean pattern (OR=1.75, 95%CI: 1.25-2.46; OR=1.56, 95%CI: 1.00-2.42). Compared with the Q4 group of egg-milk-bean pattern, the FPG control rate of the combination of "fruit-aquatic products-potato pattern (Q4 group), vegetable-grain pattern (Q2 group), egg-milk-bean pattern (Q3 group)" was higher (OR=6.79, 95%CI: 1.15-40.23, P=0.035). Compared with the Q4 group of vegetable-grain pattern, the combination of "fruit-aquatic products-potato pattern (Q4 group), vegetable-grain pattern (Q3 group), egg-milk-bean pattern (Q2 group), oil-salt pattern (Q2 group)" had higher control rate of 2 h PBG (OR=12.78, 95%CI: 1.26-130.05, P=0.031). Conclusions: A proper combination of dietary patterns and dietary patterns are more conducive to the control of FPG and 2 h PBG in T2DM patients managed in the communities of Wuhan and Changshu. Patient nutrition education should be strengthened, and the food-matching ability of patients should be improved.

Factors Associated With Low Birth Weight Among the Tribal Population in India: A Narrative Review.

Low birth weight (LBW)is defined by the WHO as a birth weighing less than 2500 g (5.5 lb). The highest burden of any nation is LBW infants. In countries where the frequencyof neonatebabies is high, short gestation is a major cause. LBW babies have an 11-13 times greater risk of delayed developmental milestones and other medical diagnoses. Greater than the globalincidence, LBW prevalence is a severe public health problem in India. A comprehensive literature search was conducted using internet sources like PubMed, Web of Science, Cochrane Library, and Google Scholar. The words "birth weight," "abnormal birth weight," "LBWs," "neonates," "premature birth," "risks factors," "causes," "factors," "prevalence," and "frequency" weresearched.In this review, we examine the causes of LBW, implementation of pre-birth prevention strategies, and post-birth multifaceted health promotion interventions. The mother's knowledge, dietary requirements, and prenatal services need to be addressed to decrease the prevalence of LBWs among tribal districts of India.

Prevalence, risk factors, and antimicrobial resistance of endemic healthcare-associated infections in Africa: a systematic review and meta-analysis

BackgroundHealthcare-associated infections (HCAI) place a significant burden on healthcare systems globally. This systematic review and meta-analysis aimed to investigate the prevalence, risk factors, and aetiologic agents of endemic HCAI in Africa.MethodsMEDLINE/PubMed, CINAHL, and Global Health databases (EBSCOhost interface) were searched for studies published in English and French describing HCAI in Africa from 2010 to 2022. We extracted data on prevalence of HCAI, risk factors, aetiologic agents, and associated antimicrobial resistance patterns. We used random-effects models to estimate parameter values with 95% confidence intervals for risk factors associated with HCAI. This study was registered in PROSPERO (CRD42022374559) and followed PRISMA 2020 guidelines.ResultsOf 2541 records screened, 92 were included, comprising data from 81,968 patients. Prevalence of HCAI varied between 1.6 and 90.2% with a median of 15% across studies. Heterogeneity (I2) varied from 93 to 99%. Contaminated wound (OR: 1.75, 95% CI: 1.31–2.19), long hospital stay (OR: 1.39, 95% CI: 0.92–1.80), urinary catheter (OR: 1.57, 95% CI: 0.35–2.78), intubation and ventilation (OR: 1.53, 95% CI: 0.85–2.22), vascular catheters (OR: 1.49, 95% CI: 0.52–2.45) were among risk factors associated with HCAI. Bacteria reported from included studies comprised 6463 isolates, with E. coli (18.3%, n = 1182), S. aureus (17.3%, n = 1118), Klebsiella spp. (17.2%, n = 1115), Pseudomonas spp. (10.3%, n = 671), and Acinetobacter spp. (6.8%, n = 438) being most common. Resistance to multiple antibiotics was common; 70.3% (IQR: 50–100) of Enterobacterales were 3rd -generation cephalosporin resistant, 70.5% (IQR: 58.8–80.3) of S. aureus were methicillin resistant and 55% (IQR: 27.3–81.3) Pseudomonas spp. were resistant to all agents tested.ConclusionsHCAI is a greater problem in Africa than other regions, however, there remains a paucity of data to guide local action. There is a clear need to develop and validate sustainable HCAI definitions in Africa to support the implementation of routine HCAI surveillance and inform implementation of context appropriate infection prevention and control strategies.

Abstract PR002: Somatic mutation rates and strength of selection on driver genes change by age in melanoma

Abstract The frequencies of driver mutations in melanoma vary in patients of different ages. However, it is unclear whether these differences in frequency are driven by variation in underlying mutation rates or by a changing selective regime in the aging body. Employing a bulk tumor sequence dataset from 5472 melanomas (459 whole-exome sequences and 5013 cancer gene-panel sequences) analyzed with the cancereffectsizeR package, we quantified somatic mutation rates and the strength of selection on somatic mutations, measuring the survival advantage conferred by a somatic mutation across the tumorigenic trajectory. Likelihood ratio tests were used to compare cancer effect sizes between age groups: &amp;lt;40 y/o, 40-59 y/o and ≥ 60 y/o. The proportion of cancer effect attributable to each mutational source was calculated by averaging over bootstrapped resample of mutational signature weights. Mann-Whitney U statistics were used to test the difference in signature weights and cancer effect sources across the groups.The underlying mutation rate increased with age, with a mean of 4.49e-6, 4.88e-6, 6.45e-6 in patients &amp;lt;40 y/o, 40-59 y/o and ≥ 60 y/o respectively. From the whole-exome and panel data, 23 variants differed significantly across age groups, among which BRAF V600E had the largest effect sizes, followed by NRAS Q61R, NRAS Q61K, NRAS Q61L. BRAF V600E were significantly larger in patients &amp;lt;40 y/o, while NRAS Q61R, NRAS Q61K, NRAS Q61L were significantly larger in patients 40-59 y/o and ≥ 60 y/o. Although underlying mutation rates and strengths of selection varied across age groups, the origin of melanomas from patients in all three age groups was predominantly attributed to UV light. These observations illuminate numerous theoretical questions regarding the origins of cancer at different ages. They are helpful to widespread implementation of prevention strategies. Moreover, understanding the relative strength of selection on driver mutations within patients at distinct ages is crucial for improving precision therapeutic interventions.

Prevalence and unfavorable outcome of frailty in older adults with gastric cancer: a systematic review and meta-analysis.

Previous studies reported inconsistent results on the prevalence and prognostic implications of frailty among older adults with gastric cancer. This systematic review synthesized available literature pertaining on this topic to establish the prevalence and unfavorable outcomes of frailty in older adults with gastric cancer. A comprehensive search was conducted across multiple English databases including PubMed, Cochrane Library, CINAHL, Embase, and Web of Science as well as Chinese databases, namely, CNKI, Wan Fang, and CBM, from inception to July 4, 2023, to identify potential studies. Data related to the incidence of frailty and its unfavorable outcomes in older adults with gastric cancer were extracted. RevMan5.3 and R 4.2.2 were used to evaluate pooled prevalence, hazard ratios (HR), and 95% confidence interval (CI). This review comprehensively selected 13 studies, comprising 9 cohort studies and 4 cross-sectional studies, on 44,117 older adults diagnosed with gastric cancer. The incidence of frailty among older adults with gastric cancer ranged from 10 to 71%. The pooled prevalence of frailty was 29% (95% CI 0.21-0.39). Frailty was found to be associated with an elevated risk of postoperative complications (HR = 1.99, 95% CI 1.45-2.73), prolonged postoperative hospital stay (HR = 2.68, 95% CI 2.38-3.02), likelihood of readmission (HR = 3.28, 95% CI 1.77-6.08), and an increased mortality risk (HR = 1.60, 95% CI 1.36-1.90). Frailty was associated with a poor prognosis in older adults with gastric cancer. Clinical medical staff should focus on the frailty of older adults with gastric cancer, conduct large-scale, multicenter, and prospective studies and early screening of patients, and provide guidance for the implementation of prevention and treatment strategies.

Programme Dementia Prevention (pdp): A Nationwide Program for Personalized Prevention in Luxembourg.

With continuously aging societies, an increase in the number of people with cognitive decline is to be expected. Aside from the development of causative treatments, the successful implementation of prevention strategies is of utmost importance to reduce the high societal burden caused by neurodegenerative diseases leading to dementia among which the most common cause is Alzheimer's disease. The aim of the Luxembourgish "programme dementia prevention (pdp)" is to prevent or at least delay dementia in an at-risk population through personalized multi-domain lifestyle interventions. The current work aims to provide a detailed overview of the methodology and presents initial results regarding the cohort characteristics and the implementation process. In the frame of the pdp, an extensive neuropsychological evaluation and risk factor assessment are conducted for each participant. Based on the results, individualized multi-domain lifestyle interventions are suggested. A total number of 450 participants (Mean age = 69.5 years; SD = 10.8) have been screened at different recruitment sites throughout the country, among whom 425 participants (94.4%) met the selection criteria. We provide evidence supporting the feasibility of implementing a nationwide dementia prevention program and achieving successful recruitment of the target population by establishing a network of different healthcare providers.

The Effects of Environmental Exposure on Epigenetic Modifications in Allergic Diseases.

Allergic diseases are one of the most common chronic conditions and their prevalence is on the rise. Environmental exposure, primarily prenatal and early life influences, affect the risk for the development and specific phenotypes of allergic diseases via epigenetic mechanisms. Exposure to pollutants, microorganisms and parasites, tobacco smoke and certain aspects of diet are known to drive epigenetic changes that are essential for immune regulation (e.g., the shift toward T helper 2-Th2 cell polarization and decrease in regulatory T-cell (Treg) differentiation). DNA methylation and histone modifications can modify immune programming related to either pro-allergic interleukin 4 (IL-4), interleukin 13 (IL-13) or counter-regulatory interferon γ (IFN-γ) production. Differential expression of small non-coding RNAs has also been linked to the risk for allergic diseases and associated with air pollution. Certain exposures and associated epigenetic mechanisms play a role in the susceptibility to allergic conditions and specific clinical manifestations of the disease, while others are thought to have a protective role against the development of allergic diseases, such as maternal and early postnatal microbial diversity, maternal helminth infections and dietary supplementation with polyunsaturated fatty acids and vitamin D. Epigenetic mechanisms are also known to be involved in mediating the response to common treatment in allergic diseases, for example, changes in histone acetylation of proinflammatory genes and in the expression of certain microRNAs are associated with the response to inhaled corticosteroids in asthma. Gaining better insight into the epigenetic regulation of allergic diseases may ultimately lead to significant improvements in the management of these conditions, earlier and more precise diagnostics, optimization of current treatment regimes, and the implementation of novel therapeutic options and prevention strategies in the near future.

Brain Health and Cognition in Older Adults: Roadmap and Milestones towards the Implementation of Preventive Strategies.

In this narrative review, we delve into the evolving concept of brain health, as recognized by the WHO, focusing on its intersection with cognitive decline. We emphasize the imperative need for preventive strategies, particularly in older adults. We describe the target population that might benefit the most from risk-based approaches-namely, people with subjective cognitive decline. Additionally, we consider universal prevention in cognitively unimpaired middle-aged and older adults. Delving into multidomain personalized preventive strategies, we report on empirical evidence surrounding modifiable risk factors and interventions crucial in mitigating cognitive decline. Next, we highlight the emergence of brain health services (BHS). We explain their proposed role in risk assessment, risk communication, and tailored interventions to reduce the risk of dementia. Commenting on ongoing BHS pilot experiences, we present the inception and framework of our own BHS in Monza, Italy, outlining its operational structure and care pathways. We emphasize the need for global collaboration and intensified research efforts to address the intricate determinants of brain health and their potential impact on healthcare systems worldwide.

Eliminating mother-to-child transmission of hepatitis B virus: practice and progress in Baoan, a national pilot district of China

BackgroundWhile mother-to-child transmission (MTCT) of hepatitis B virus (HBV) remains a significant challenge in China, research investigating the effectiveness of the September 2017 pilot program to eliminate MTCT of HIV, syphilis, and HBV is limited. Baoan district, which has a higher-than-average rate of hepatitis B infection among pregnant women and strong support from the government, was one of six national pilot districts selected for the program. Therefore, this study aims to assess the progress and implementation of the elimination of MTCT of HBV in Baoan district over a period of 5 years.MethodsData was collected from the national information system for the prevention of MTCT, registration forms, and follow-up forms of pregnant women and their live births from 2018 to 2022. Joinpoint models were used to analyze changing trends over time, calculating annual percentage change (APC) and the corresponding 95% confidence interval (95%CI). Multivariate logistic regression models were used to analyze risk factors for HBV MTCT.ResultsFrom 2018 to 2022, the coverage of HBV screening during pregnancy increased from 98.29 to 99.55% (APC = 0.30, P = 0.012). The coverage of HBV early screening within 13 gestational weeks increased from 40.76 to 86.42% (APC = 18.88, P = 0.033). The prevalence of maternal HBV infection declined by an APC of − 3.50 (95% CI -6.28 ~ − 0.63). The coverage of antiviral therapy among high-risk pregnant women increased from 63.59 to 90.04% (APC = 11.90, P = 0.031). Coverage for timely administration of hepatitis B immunoglobulin, hepatitis B birth dose vaccine, and three-dose hepatitis B vaccination remained consistently above 97.50%. The coverage of post-vaccination serological testing (PVST) in high-risk infants was 56.15% (1352/2408), and the MTCT rate of HBV was 0.18%. Mothers with high-school education or below (OR = 3.76, 95% CI 1.04 ~ 13.60, P = 0.04) and hepatitis B e antigen (HBeAg) positivity (OR = 18.89, 95% CI 1.98 ~ 18.50, P = 0.01) had increased MTCT risk.ConclusionsThe implementation of comprehensive prevention strategies in Baoan district, including screening, treatment, and immunoprophylaxis, has proven effective in maintaining the MTCT of HBV at an extremely low level. However, it remains crucial to raise public awareness, specifically on the importance of improving the coverage of PVST for infants exposed to HBV.
