A Longitudinal Examination of HIV Risk Perception Accuracy among Sexual Minority Men with History of Childhood Sexual Abuse

Men who have sex with men (MSM) with history of childhood sexual abuse (CSA) are at high risk for HIV acquisition. One reason is posttraumatic responses compromise ability to accurately appraise risk for danger/vulnerability. Health behavior change models and related interventions assume risk perception can be changed in an enduring manner. Given paucity of studies examining how risk perception changes or sustains over time post-intervention, this underlying assumption is not confirmed. Among this particularly high-risk group who struggle with perceiving risk due to trauma-related cognitions, it may be accuracy of risk perception is fluid. The study primarily aimed to examine accuracy of HIV risk perception over time post-HIV prevention behavioral intervention. Leveraging data from a larger RCT, N = 190 MSM in Boston, MA and Miami, FL USA completed a psychosocial baseline assessment, an intervention aimed to increase awareness of personal HIV risk level, then four follow-up assessments three months apart for a year. Linear mixed effect models were used to examine the degree to which accuracy of HIV risk perception (vs. traditional construct of risk perception with no information about accuracy) predicts sex risk behavior over time delineated by between-person (trait level) and within-person (state level) effects. Majority (92%) of participants fluctuated in HIV risk accuracy over time post-intervention. Within-person risk accuracy (one's accuracy at any given timepoint) predicted sex risk behavior (condomless sex not protected by adherent PrEP) over time, but not between-person (one's average of accuracy). Findings have implications for intervention and counseling related to specific HIV prevention strategies.

The Effectiveness and Safety of Intrapartum or Postpartum Catheterization in the Prevention of Postpartum Urinary Retention: A Scoping Review

INTRODUCTION AND HYPOTHESIS

Catheterization is a common treatment for postpartum urinary retention (PUR); however, its application before diagnosis of PUR remains unclear. The aim was to give an overview of the existing literature on the effectiveness and safety of intrapartum or postpartum catheterization in the prevention of PUR.

METHODS

This scoping review followed a methodological framework. PubMed, the Cochrane Library, Embase, Web of Science, the China National Knowledge Infrastructure, WanFang, the China Science and Technology Journal Database, and the China Biomedical Literature Database were searched from the inception of each database to 21 May 2023.

RESULTS

The search revealed 16 studies examining three different catheterization methodologies, including 12 intrapartum studies. Ten studies concluded that intrapartum or postpartum catheterization prevented PUR, two of which were only for overt or covert PUR. In 4 out of 13 experimental studies, no significant difference was found: one for intrapartum catheterization versus routine nursing, the other for intrapartum or postpartum intermittent versus indwelling catheterization. However, one found that postpartum disposable catheterization after ineffective targeted care reduced the incidence of PUR compared with indwelling catheterization. One out of the 3 case-control studies concluded that prenatal catheterization ≥2 times was a risk factor for PUR.

CONCLUSIONS

Based on the findings in this scoping review, catheterization prior to the diagnosis of PUR appears to play a role in preventing PUR and is safe. Preliminary evidence is accumulating on the effectiveness of three types of catheterization methods in preventing PUR, but more comprehensive studies are needed to establish these findings.

Assessing Moroccan physician knowledge and practices regarding maternal obesity's impact on childhood obesity: Implications for prevention and intervention

BACKGROUND

Childhood obesity is a growing global concern with far-reaching health implications. This study focuses on evaluating the knowledge and practices of physicians in Morocco regarding the link between maternal obesity and childhood obesity. Despite the increasing prevalence of childhood obesity worldwide, this issue remains inadequately addressed in the Moroccan context.

AIM

To assess the awareness and practices of physicians in Morocco concerning the connection between maternal obesity and childhood obesity.

METHODS

The research encompasses a comprehensive survey of practicing physicians, revealing significant gaps in awareness and practices related to maternal obesity.

RESULTS

Notably, a significant portion of doctors do not provide adequate guidance to overweight pregnant women, highlighting the urgency for targeted educational programs.

CONCLUSION

In conclusion, this research illuminates critical areas for improvement in tackling childhood obesity in Morocco. By addressing these gaps, fostering awareness, and enhancing medical practices, the healthcare system can contribute significantly to preventing childhood obesity and improving the overall health of future generations.

Daily oral administration of probiotics engineered to constantly secrete short-chain fatty acids effectively prevents myocardial injury from subsequent ischemic heart disease

AIM

Given the extremely limited regeneration potential of the heart, one of the most effective strategies to reduce the prevalence and mortality of coronary artery disease is prevention. Short-chain fatty acids (SCFAs), which are by-products of beneficial probiotics, have been reported to possess cardioprotective effects. Despite their beneficial roles, delivering SCFAs and maintaining their effective concentration in plasma present major challenges. Therefore, in the present study, we aimed to devise a strategy to prevent coronary heart disease effectively by using engineered probiotics to continuously release SCFAs in vivo.

METHODS AND RESULTS

We engineered a novel probiotic cocktail, EcN_TL, from the commercially available Escherichia coli Nissle 1917 strain to continuously secrete SCFAs by introducing the propionate and butyrate biosynthetic pathways. Oral administration of EcN_TL enhanced and maintained an effective concentration of SCFAs in the plasma. As a preventative strategy, we observed that daily intake of EcN_TL for 14 days prior to ischemia-reperfusion injury significantly reduced myocardial injury and improved cardiac performance compared to EcN administration. We uncovered that EcN_TL's protective mechanisms included reducing neutrophil infiltration into the infarct site and promoting the polarization of wound-healing macrophages. We further revealed that SCFAs at plasma concentration protected cardiomyocytes from inflammation by suppressing the NF-κB activation pathway.

CONCLUSIONS

These data provide strong evidence to support the use of SCFA-secreting probiotics to prevent coronary heart disease. Since SCFAs also play a key role in other metabolic diseases, EcN_TL can potentially be used to treat a variety of other diseases.

US Population Eligibility and Estimated Impact of Tirzepatide Treatment on Obesity Prevalence and Cardiovascular Disease Events

PURPOSE

Tirzepatide promotes weight loss and reduces risk factors for cardiovascular disease (CVD) in adults with overweight and obesity. We examined the number of US adults eligible for tirzepatide and its impact on obesity and CVD events.

METHODS

We identified US adults aged ≥ 18 years from the cross-sectional US National Health and Nutrition Examination Survey (NHANES) 2015-2018 eligible for tirzepatide based on SURMOUNT-1 trial eligibility criteria. Weight changes in SURMOUNT-1 from tirzepatide 15 mg treatment were used to project the impact on weight change and obesity prevalence in the population assuming titration to this dosage. We estimated 10-year CVD risks from BMI-based Framingham CVD risk scores before and after applying tirzepatide 15 mg treatment BMI and risk factor effects from SURMOUNT-1, the differences in estimated risks multiplied by the eligible NHANES weighted population representing the estimated "preventable" CVD events.

RESULTS

We identified 4015 US adults (estimated population size of 93.4 million [M]) to fit SURMOUNT-1 eligibility criteria, representing 38% of US adults. When the effects of 15 mg tirzepatide were applied, we estimated 70.6% (65.9 M) and 56.7% (53.0 M) of adults to show ≥ 15% and ≥ 20% reductions in weight, respectively, translating to 58.8% (55.0 M) fewer persons with obesity. Among those without CVD, estimated 10-year CVD risks were 10.1% "before" and 7.7% "after" tirzepatide "treatment" reflecting a 2.4% absolute (and 23.6% relative) risk reduction translating to 2.0 million preventable CVD events over 10 years.

CONCLUSION

Tirzepatide treatment in appropriate US adults may substantially reduce obesity prevalence and CVD events, impacting beneficially on associated healthcare costs.

Could the periodontal therapy improve the cardiologic patient health? A narrative review

BACKGROUND

Cardiovascular diseases (CVD) is the major cause of mortality globally, with increasing evidence suggesting a link between periodontitis, and CVD. This study aims to explore the association between periodontitis and CVD, and the impact of periodontal therapy on cardiovascular health.

METHODS

This review synthesized findings from preclinical and clinical studies, without publication year restrictions, examining periodontitis and CVD through various lenses. Scientific databases were inspected with keywords related to periodontitis and CVD.

RESULTS

The review identifies a substantial association between periodontitis and an increased risk of several CVD, supported by both epidemiological and interventional studies. Results suggest the complexity of the relationship, influenced by factors like the severity of periodontitis and the presence of other systemic conditions. Clinical data indicates that periodontal therapy, particularly non-surgical periodontal therapy, may reduce systemic inflammatory markers and thus may play a role in the primary and secondary prevention of CVD events, highlighting the potential of periodontal therapy to not only maintain oral health but also to modulate cardiovascular risk factors.

CONCLUSIONS

Current evidence supports a significant association between periodontitis and increased cardiovascular risk, promoting integrated healthcare approaches that consider oral health as a key-component of cardiovascular care and wellbeing.

Developing a comprehensive abortion prevention program for couples based on I-change model: study protocol for a mixed method research

BACKGROUND

In countries where abortion laws are stringent, induced abortions are prevalent. The limited availability of abortion services within these regions amplifies the likelihood of maternal complications and mortality. Induced abortions represent a significant public health concern in Iran and are characterized by a multitude of intricate factors that remain largely unexplored. Gaps in knowledge persist pertaining to the influences driving induced abortion within the Iranian context. To adequately address the issue of induced abortion, it is imperative to discern the determinants that shape the decision-making process. The primary objective of this study was to design an intervention program focused on mitigating the occurrence of induced abortion within couples, with an emphasis on identifying the key factors that contribute to this phenomenon.

METHODS

This study comprises three phases. In the first phase, a qualitative approach based on the I-change model will be employed to identify the factors influencing induced abortion. The second phase involves a systematic review to identify the determinants of induced abortion and strategies to prevent induced abortion. In the third phase, the outcomes of the qualitative approach and systematic review will be shared with experts and specialists using the Delphi method to categorize and prioritize strategies. Subsequently, based on the final consensus, a comprehensive program will be developed to prevent induced abortion.

DISCUSSION

This study introduces an I-change model-based program for the prevention of induced abortion. The prevention of induced abortion holds great significance in mitigating maternal morbidity and mortality, curtailing healthcare expenses, and fostering population growth rates. The research findings will be disseminated via reputable peer-reviewed journals and communicated to the academic and medical communities. This dissemination aims to provide valuable insights that can contribute to the advancement of induced abortion and abortion prevention programs.

Addressing muscle-tendon imbalances in adult male athletes with personalized exercise prescription based on tendon strain

PURPOSE

Imbalances of muscle strength and tendon stiffness can increase the operating strain of tendons and risk of injury. Here, we used a new approach to identify muscle-tendon imbalances and personalize exercise prescription based on tendon strain during maximum voluntary contractions (εmax) to mitigate musculotendinous imbalances in male adult volleyball athletes.

METHODS

Four times over a season, we measured knee extensor strength and patellar tendon mechanical properties using dynamometry and ultrasonography. Tendon micromorphology was evaluated through an ultrasound peak spatial frequency (PSF) analysis. While a control group (n = 12) continued their regular training, an intervention group (n = 10) performed exercises (3 × /week) with personalized loads to elicit tendon strains that promote tendon adaptation (i.e., 4.5-6.5%).

RESULTS

Based on a linear mixed model, εmax increased significantly in the control group over the 9 months of observation (pCon = 0.010), while there was no systematic change in the intervention group (pInt = 0.575). The model residuals of εmax, as a measure of imbalances in muscle-tendon adaptation, demonstrated a significant reduction over time exclusively in the intervention group (pInt = 0.007). While knee extensor muscle strength increased in both groups by ~ 8% (pCon < 0.001, pInt = 0.064), only the intervention group showed a trend toward increased normalized tendon stiffness (pCon = 0.824, pInt = 0.051). PSF values did not change significantly in either group (p > 0.05).

CONCLUSION

These results suggest that personalized exercise prescription can reduce muscle-tendon imbalances in athletes and could provide new opportunities for tendon injury prevention.

IOC Olympian Health Cohort: a study protocol for a 15-year, prospective, Olympian health study across Summer and Winter Olympic sports

Prevention of sports injury and illness and protection of athlete health are key mandates of the IOC. Methodological limitations in Olympic Games surveillance and retired Olympian studies mean there are gaps in the available evidence on Olympian health and the varied challenges occurring at different stages throughout an athlete's career. This (protocol) paper describes the methods for implementation of the IOC Olympian Health Cohort. The study aims to establish a longitudinal cohort of current Olympians and follow them prospectively (around 15 years) throughout their Olympic careers and retirement. The study will use participants who have completed self-report questionnaires. Olympians will be recruited after each Summer and Winter Olympic Games, and all National Olympic Committee (NOC) athletes aged 16 years or older are eligible. The first phase included the Tokyo 2020/2021 and Beijing 2022 Olympians, with the study promoted via IOC platforms, Athlete365 and NOCs. Questionnaires include baseline demographics, sports exposure and history of injuries and illnesses impacting the athlete's ability to continue to train and/or compete for at least 2 weeks. Questions also address retirement from sports, musculoskeletal, mental and general health, and quality of life measures. This protocol describes the methods for the 15-year global IOC Olympian Health Cohort Study, from participant recruitment to the development and distribution of the study questionnaire. This protocol will be updated to report future changes in the study's conduct or questionnaire content. These data will help identify risk factors and inform risk-reduction strategies. The ultimate goal is to protect the health of all athletes during their careers and retirement.

The Effects of Low Concentrations of Pravastatin on Placental Cells

Pravastatin is a promising medication to treat preeclampsia. However, the appropriate dose of pravastatin for managing preeclampsia has not been established. In this in vitro study, we examined the effects of low concentrations of pravastatin (0.01 to 10 µM) under hypoxic conditions on two types of placental cells and found that pravastatin decreased sFlt-1 levels up to 34% in cytotrophoblast cells isolated from human term placentas. Furthermore, we showed that sFlt-1 levels in HTR-8/SVneo cells, a cell line derived from first trimester trophoblast cells, decreased after exposure to very low concentrations of pravastatin (0.01, 0.1 µM). We also examined the effects of pravastatin on uterine spiral artery remodeling-related events and showed in wound healing and tube formation assays that low concentrations of pravastatin upregulated cell migration and invasion in HTR-8/SVneo cells. These results demonstrated that a low dose of pravastatin has in vitro effects that suggest a potential for anti-preeclamptic effects in vivo.

World Psychiatric Association-Asian Journal of Psychiatry Commission on Public Mental Health

Although there is considerable evidence showing that the prevention of mental illnesses and adverse outcomes and mental health promotion can help people lead better and more functional lives, public mental health remains overlooked in the broader contexts of psychiatry and public health. Likewise, in undergraduate and postgraduate medical curricula, prevention and mental health promotion have often been ignored. However, there has been a recent increase in interest in public mental health, including an emphasis on the prevention of psychiatric disorders and improving individual and community wellbeing to support life trajectories, from childhood through to adulthood and into older age. These lifespan approaches have significant potential to reduce the onset of mental illnesses and the related burdens for the individual and communities, as well as mitigating social, economic, and political costs. Informed by principles of social justice and respect for human rights, this may be especially important for addressing salient problems in communities with distinct vulnerabilities, where prominent disadvantages and barriers for care delivery exist. Therefore, this Commission aims to address these topics, providing a narrative overview of relevant literature and suggesting ways forward. Additionally, proposals for improving mental health and preventing mental illnesses and adverse outcomes are presented, particularly amongst at-risk populations.

Physical exercise in hypertensive heart disease: From the differential diagnosis to the complementary role of exercise

Arterial hypertension (AH) is one of the most common pathologic conditions and uncontrolled AH is a leading risk factor for cardiovascular disease and mortality. AH chronically causes myocardial and arterial remodelling with hemodynamic changes affecting the heart and other organs, with potentially irreversible consequences leading to poor outcomes. Therefore, a proper and early treatment of AH is crucial after the diagnosis. Beyond medical treatment, physical exercise also plays a therapeutic role in reducing blood pressure, given its potential effects on sympathetic tone, renin-angiotensin-aldosterone system, and endothelial function. International scientific societies recommend physical exercise among lifestyle modifications to treat AH in the first stages of the disease. Moreover, some studies have also shown its usefulness in addition to drugs to reduce blood pressure further. Therefore, an accurate, personalized exercise prescription is recommended to optimize the prevention and treatment of hypertension. On the other hand, uncontrolled AH in athletes requires proper risk stratification and careful evaluation to practice competitive sports safely. Moreover, the differential diagnosis between hypertensive heart disease and athlete's heart is sometimes challenging and requires a careful and comprehensive interpretation in order not to misinterpret the clinical findings. The present review aims to discuss the relationship between hypertensive heart disease and physical exercise, from diagnostic tools to prevention and treatment strategies.

Impact of cigarette price and tobacco control policies on youth smoking experimentation in Albania

BACKGROUND

Albania has one of the highest smoking prevalence in Europe especially among the youth. There is a lack of evidence in Albania, as well as in most of Eastern Europe and middle-income countries, regarding the effect of price on smoking experimentation.

OBJECTIVE

The study aims to assess the effect of price and tobacco control policies on youth smoking experimentation in Albania.

METHODS

We used microdata from the Global Youth Tobacco Survey in Albania for 2004, 2009, 2015 and 2020. We constructed a pseudo-longitudinal dataset and estimated a split-population model to assess the hazard of smoking experimentation.

RESULTS

Price is a significant predictor of smoking experimentation among teenagers in Albania for both males and females (p<0.001). Being male increases the odds for smoking experimentation by more than 50% as compared with females (p<0.001), whereas females appear to be more price sensitive. Peer and parent smoking are also important determinants for smoking experimentation. Introducing penalties for smokers and legal entities violating smoke-free policies implemented in 2014 is also associated with a lower hazard of smoking experimentation.

CONCLUSION

Price is a significant predictor of smoking experimentation among teenagers in Albania for both males and females. A combination of increasing taxes and strengthening the rule of law to control tobacco use in public spaces, in addition to public awareness campaigns targeting both youth and smoking parents, could help to significantly reduce the probability of smoking experimentation.

Overdose prevention activities led by local public health departments, 2019-2023

BACKGROUND

Drug overdose deaths in the United States increased to historic levels in recent years, with provisional estimates indicating more than 111,000 deaths in the 12 months ending July 2023. In 2019, the Centers for Disease Control and Prevention's Division of Overdose Prevention in collaboration with the National Association of City and County Health Officials, funded local health departments (LHDs) to work on overdose prevention activities. This paper aims to: 1) describe the overdose prevention activities that LHDs implemented during the four eighteen-month funding cycles; 2) identify programmatic successes and areas of opportunity for LHDs to consider when implementing future overdose prevention activities; and to 3) inform policy considerations and future overdose prevention programming at the local level.

METHODS

We used programmatic data to identify overdose prevention activities implemented by 45 LHDs. Activities were double-coded according to the social-ecological model and the U.S. Department of Health and Human Services Overdose Prevention Strategies and Guiding Principles. We analyzed final codes to identify distribution and overlap of the Strategies and Guiding Principles across the social ecological model co-occurrences.

RESULTS

Approximately 55.9% (n=123) of the 220 overdose prevention activities that were coded took place at the community level, 32.3% (n=71) at the individual level, 8.6% (n=19) at the relationship level, and 3.2% (n=7) at the policy level. Most of the activities were coded as coordination, collaboration, and integration (n=52, 23.6%), harm reduction (n=51, 23.1%), data and evidence (n=47, 21.4%) or reducing stigma (n=24, 10.9%). Few activities were related to primary prevention (n=14, 6.4%), equity (n=14, 6.4%), recovery support (n=11, 5.0%), and evidence-based treatment (n=7, 3.2%).

CONCLUSIONS

Localities have primarily implemented activities focused on the community and individual levels, with most of these centered around coordination, collaboration, and integration; harm reduction; or data and evidence. This study identified gaps in overdose prevention for LHDs related to treatment and health equity and that more interventions should be implemented at the relationship and policy levels. Continuing these efforts is important as LHDs explore opportunities to enhance and expand their work in various strategy areas across the social ecology. Findings from this study may be used to inform localities as they design and implement future overdose prevention activities.

Diabetes type 2 prevalence is rising among young residents in Malmö, Sweden

AIM

Type 2 diabetes is becoming more prevalent in many parts of the world. Malmö's population has increased in recent years mainly because of migration from other parts of Sweden and the world in addition to increased birth rates. We aimed to explore diabetes prevalence in Malmö in 2011-2018 as well as the achieved treatment targets for selected diabetes-related outcomes.

METHOD

The current study is a part of the Cities Changing Diabetes Malmö project. Prevalence data were retrieved from the region's primary care and hospital diagnosis register, and data on treatment targets were collected from the National Diabetes Register. The inclusion criteria were either being a resident of Malmö or using a primary healthcare centre located in Malmö.

RESULTS

The prevalence of type 2 diabetes in 2018 doubled from 2011 in the entire Malmö population. During the same period, the prevalence of type 1 diabetes remained stable at 0.49 %. In 2011, the type 2 diabetes prevalence was 2.46 % (2.76 % for males and 2.28 % for females), and in 2018, it was 4.26 % (4.84 % for males and 3.82 % for females). The increase was 139 % for residents aged 0-29 years, 119.6 % for residents aged 30-39 years, 96.2 % for residents aged 40-49 years, 102 % for residents aged 50-59 years, 98.2 % for residents aged 60-69 years, and 115.5 % for those aged 70-79 years. Finally, the increase was 60.9 % for those aged 80-84 years and 90.7 % for residents 90 years of age and older. The National Diabetes Register reported that during 2019, 58 % of all patients with diabetes using primary care in Malmö reached HbA1c <52 mmol/mol, 20 % had albuminuria, 36 % had retinopathy, and 21 % had not had their feet inspected by a healthcare professional during the last year. The median HbA1c was 52.6 mmol/mol, and 17 % were registered as active smokers.

CONCLUSION

Diabetes prevalence in Malmö has increased markedly in recent years, exacerbated by a rise in type 2 diabetes mainly in the younger population. Targets regarding p-glucose lowering treatments were not met by 42 %. One patient out of three had microvascular complications in the eye, one out of five had impaired kidney function, one out of five had not had their feet inspected, and one out of five was an active smoker. Active diabetes treatments need to be improved to reduce the number of younger patients developing microvascular complications. Preventive activities need to target younger populations to counteract even more residents developing type 2 diabetes.

Herpes Zoster Ophthalmicus: Presentation, Complications, Treatment, and Prevention

Herpes zoster (HZ) is caused by reactivation of latent infection of varicella zoster virus (VZV) in sensory (cranial, dorsal root) ganglia. Major risk factors for HZ are increasing age and immunosuppression. HZ ophthalmicus (HZO) is a subset of HZ with involvement of the ophthalmic division of the fifth cranial trigeminal nerve. Approximately 4-20% of patients with HZ develop HZO. Approximately 50% of patients with HZO develop ocular disease, among whom up to 25% develop chronic or recurrent disease. Common manifestations of ocular disease include conjunctivitis, keratitis, and uveitis, whereas optic neuropathy and retinitis are uncommon. Due to the potential for vision impairment, ocular involvement requires urgent ophthalmic consultation. Early recognition and timely treatment with antivirals may prevent ocular complications. HZO is preventable by vaccination against HZ. Vaccine efficacy/effectiveness studies have been largely conducted for HZ with few studies assessing HZO. Both the recombinant adjuvanted vaccine (RZV) and live-attenuated vaccine (ZVL) significantly reduce the incidence of HZ and HZO in older adults. RZV is more effective than ZVL. Data on the effectiveness of vaccines for prevention of recurrent disease in patients with HZO are limited; however, vaccination is recommended. Despite recommendations to vaccinate individuals likely to benefit from an HZ vaccine, coverage for adults remains suboptimal. Barriers to vaccination include patient beliefs about HZ or HZ vaccines, and factors related to healthcare providers. In particular, the lack of a recommendation from their primary care physician is often cited by patients as a reason for remaining unvaccinated. By encouraging vaccination against HZ, physicians not only prevent HZ and HZO but also potential vision loss due to HZO.Graphical abstract available for this article.

Assessing nutrition-related knowledge, attitudes, and practices towards breast cancer prevention among female students at the Federal University of Oye-Ekiti, Nigeria

BACKGROUND

Breast cancer remains a complex disease and leading cause of cancer-related death in Nigerian women. Recently, the role of nutrition has been highlighted in the etiology of breast cancer.

METHODS

The aim of this research was to evaluate the nutrition-related knowledge, attitude, and practices of female university students. We also investigated the correlation between their demographic characteristics and their knowledge and attitudes of the survey participants. A descriptive cross-sectional study was carried out among female students at the Federal University of Oye (FUOYE), Nigeria. Participants completed self-administered questionnaires designed to assess their knowledge, attitude, and practices concerning cancer prevention. Statistical analysis was performed using SPSS 20, and significance was set at p < 0.05.

RESULTS

Out of the 402 students who received the questionnaire, 300 completed it. The average age of the participants was 21.26 years with a standard deviation of 2.68. There was generally limited knowledge regarding breast cancer risk factors, with 45% of participants citing family history as the most recognized risk factor. Overall, knowledge level was influenced by the participants' permanent place of residence and course of study. Attitudes towards the impact of maternal and paternal nutrition on breast cancer prevention were notably low. Additionally, less than half of the participants demonstrated good dietary practices.

CONCLUSION

This study revealed low levels of nutrition-related knowledge concerning cancer prevention, accompanied by poor dietary habits among the participants. These results suggest a possible link between inadequate knowledge about breast cancer prevention and the observed poor dietary practices among the participants. The frequent consumption of unhealthy foods among the participants may be a pointer to higher risk of breast cancer in the future, emphasizing a need for health education targeted at this group.

Effect of a multimodal intervention in breast Cancer patients undergoing neoadjuvant therapy: A study protocol of the multimodal project

BACKGROUND AND AIMS

To determine the effect of a multimodal intervention (nutritional behavior change and physical exercise) on quality of life, chemotherapy response rate and tolerance, histopathological level of the tumor, body composition, and biochemical parameters, in patients diagnosed with breast cancer during neoadjuvant chemotherapy treatment, and to compare them with the control group.

METHODS

Anticipated 80 patients diagnosed with breast cancer aged 18-70 years will be recruited for this randomized, unblinded clinical trial based on a nutritional behavior change and physical exercise in patients during the approximately 6 months in which the patient receives neoadjuvant treatment. Participants will be randomly allocated (1:1) to one of two groups (intervention or control). Primary and secondary outcomes will be assessed before the beginning and after the neoadjuvant treatment (before surgery). The primary outcome is quality of life, whereas secondary outcomes include chemotherapy response rate and tolerance, histopathological level of the tumor and body composition (i.e., visceral adipose tissue activity, bone, lean and fat masses). We will analyze blood parameters (i.e., biochemical, inflammatory, and tumor markers) as exploratory outcomes.

CONCLUSION

This study will address the influence of a practical and viable multimodal intervention (i.e., nutritional behavior change and physical exercise) on breast cancer patients undergoing neoadjuvant chemotherapy. Given the practical viability of the intervention in real-world settings, our study holds promise for significant scientific and clinical implications.

Prophylactic nicotinamide mononucleotide (NMN) mitigates CSDS-induced depressive-like behaviors in mice via preserving of ATP level in the mPFC

Depression is a prevalent psychiatric disorder with accumulating evidence implicating dysregulation of extracellular adenosine triphosphate (ATP) levels in the medial prefrontal cortex (mPFC). It remains unclear whether facilitating endogenous ATP production and subsequently increasing extracellular ATP level in the mPFC can exert a prophylactic effect against chronic social defeat stress (CSDS)-induced depressive-like behaviors and enhance stress resilience. Here, we found that nicotinamide mononucleotide (NMN) treatment effectively elevated nicotinamide adenine dinucleotide (NAD+) biosynthesis and extracellular ATP levels in the mPFC. Moreover, both the 2-week intraperitoneal (i.p.) injection and 3-week oral gavage of NMN prior to exposure to CSDS effectively prevented the development of depressive-like behavior in mice. These protective effects were accompanied with the preservation of both NAD+ biosynthesis and extracellular ATP level in the mPFC. Furthermore, catalyzing ATP hydrolysis by mPFC injection of the ATPase apyrase negated the prophylactic effects of NMN on CSDS-induced depressive-like behaviors. Prophylactic NMN treatment also prevented the reduction in GABAergic inhibition and the increase in excitability in mPFC neurons projecting to the lateral habenula (LHb). Collectively, these findings demonstrate that the prophylactic effects of NMN on depressive-like behaviors are mediated by preventing extracellular ATP loss in the mPFC, which highlights the potential of NMN supplementation as a novel approach for protecting and preventing stress-induced depression in susceptible individuals.

Autopsy of all young sudden death cases is important to increase survival in family members left behind

Sudden cardiac death (SCD) is an important public health problem worldwide, accounting for an estimated 6-20% of total mortality. A significant proportion of SCD is caused by inherited heart disease, especially among the young. An autopsy is crucial to establish a diagnosis of inherited heart disease, allowing for subsequent identification of family members who require cardiac evaluation. Autopsy of cases of unexplained sudden death in the young is recommended by both the European Society of Cardiology and the American Heart Association. Overall autopsy rates, however, have been declining in many countries across the globe, and there is a lack of skilled trained pathologists able to carry out full autopsies. Recent studies show that not all cases of sudden death in the young are autopsied, likely due to financial, administrative, and organizational limitations as well as awareness among police, legal authorities, and physicians. Consequently, diagnoses of inherited heart disease are likely missed, along with the opportunity for treatment and prevention among surviving relatives. This article reviews the evidence for the role of autopsy in sudden death, how the cardiologist should interpret the autopsy-record, and how this can be integrated and implemented in clinical practice. Finally, we identify areas for future research along with potential for healthcare reform aimed at increasing autopsy awareness and ultimately reducing mortality from SCD.

Cancer Prevention and Screening for People Living with Human Immunodeficiency Virus

People living with human immunodeficiency virus (HIV) (PLWH) live near-normal life expectancies due to advances in antiretroviral therapy. PLWH are experiencing more non-HIV-related comorbidities and deaths. PLWH are diagnosed with cancer more often and experience worse cancer-related outcomes than the general population. Cancer prevention and screening in PLWH is essential and leads to earlier diagnosis and treatment which may result in improved health outcomes and increased long-term survival. Few cancer screening guidelines specific to PLWH exist. There are often discrepancies in general population cancer screening guidelines. Familiarity with the utilization of cancer screening guidelines in this population is imperative.

Evaluation of Effectiveness of the Unplugged Program on Gambling Behaviours among Adolescents: Study Protocol of the Experimental Controlled Study "GAPUnplugged"

Gambling risk behaviour is an emerging problem among adolescents. "Unplugged" is an effective Social Influence curriculum for preventing substance use among students. This study aims to develop and test a new component focused on gambling added to the Unplugged program. Schools of Piedmont region and Rome city were invited to participate in the study. A self-completed anonymous questionnaire including questions on socio-demographic characteristics, addictive behaviours, beliefs, attitudes and risk perceptions about gambling, normative perceptions, parental practices, school climate, refusal skills, impulsiveness, self-esteem, antisocial behaviours and sensation seeking was prepared for baseline and follow-up surveys. The protocol of the study was submitted and approved by the Novara Ethical Committee and registered in ClinicalTrials.gov (NCT05630157, Protocol ID: 080.742, 11/17/2022). Twenty-nine schools accepted to participate in the study. Sixty-three classes (1325 students) satisfied the eligibility criteria for intervention and were allocated to the intervention arm, and the other 61 (1269 students) were allocated to the control arm. Because of drop-out, absentees, refusals, and invalid questionnaires, data on 1874 students (998 in the intervention and 876 in the control arm), were available for the analysis at baseline. Data management of follow-up questionnaires is in progress. Results of the present study will be useful to clarify the effectiveness of prevention interventions in reducing gambling behaviours among adolescents. Moreover, this will be the first experience of evaluating a new component focused on a different risk behaviour, added to a curriculum previously shown as effective on other risk behaviours.

Restarting pre-exposure prophylaxis (PrEP) for HIV: a systematic review and meta-analysis

Background

High coverage of pre-exposure prophylaxis (PrEP) will reduce HIV transmission and help end the HIV/AIDS pandemic. However, PrEP users face challenges, including long-term adherence. The study aimed to document the proportions of individuals who restart HIV PrEP after they stop and the reasons for restarting PrEP.

Methods

This study is a systematic review and meta-analysis. We systematically searched CINAHL, Embase, Emcare, Global Health, Medline, Scopus, and PsychINFO for peer-reviewed with no date restrictions. A grey literature search was conducted through Google search, a search of abstract books of AIDS conferences and the websites of WHO and UNAIDS. The data search was conducted in April 2023 and updated in February 2024. Two authors extracted data on the proportion of people who stopped and then restarted PrEP, reasons for restarting, and strategies to support people restarting PrEP. Two authors appraised the data using the Joanna Briggs Institute Appraisal Tools. We used a random-effects meta-analysis to pool estimates of restarting. We conducted meta-regression to determine potential sources of heterogeneity. This study is registered with PROSPERO, CRD42023416777. However, we deviated from our original plan as we did not identify enough studies for strategies to support restarting PrEP (primary objective). Subsequently, we revised our plan to strengthen our secondary objective to quantify the proportion of people who stopped and restarted PrEP, and explore possible reasons for its heterogeneity.

Findings

Of 988 studies, 30 unique studieswere included: 27 reported the proportion restarting PrEP, and of these, 7 also reported reasons for restarting PrEP, and 3 studies reported only on the reasons for restarting PrEP. No study evaluated interventions for restarting PrEP. For the meta-analysis, we included 27 studies. Most studies were from high-income countries (17/27, 63%) or the USA (15/27, 56%). Overall, 23.8% (95% CI: 15.9-32.7, I2 = 99.8%, N = 85,683) of people who stopped PrEP restarted PrEP. There was a lower proportion of restarting in studies from middle-income countries compared to high-income countries (adjusted odds ratio (aOR) 0.6, 95% CI: 0.50-0.73, p < 0.001). There was higher restarting in studies from Africa compared to the USA (aOR 1.55, 95% CI: 1.30-1.86), heterosexual populations compared to men who have sex with men or transgender women (aOR 1.50, 95% CI: 1.25-1.81, p < 0.001) and in studies defining restarting as those who had stopped PrEP for >1 month compared to those who stopped <1 month (aOR 1.20, 95% CI: 1.06-1.36, p < 0.001). Reasons for restarting PrEP included perceived higher risk for HIV acquisition and removal of barriers to access PrEP. In terms of quality assessment, overall, both randomised controlled trials had a low risk of bias, while the observational studies used in the meta-analysis had some potential risk of bias related to not explicitly addressing potential confounders (15/25, 60%) or not describing strategies to address incomplete follow-up (24/25, 96%).

Interpretation

About a quarter of people who stopped PrEP would restart, with substantial variation across countries and populations. It is important to understand the motivations and contextual factors influencing restarting PrEP and the support systems to enable restarting PrEP for those at ongoing risk.

Burnout Syndrome Among Catholic Clergy: A Systematic Review

Burnout syndrome implies exhaustion, loss of motivation, low performance, and absenteeism. Catholic clergy are not exempt. This systematic review compiles and analyzes evidence related to burnout in Catholic clergy and potential modulating variables. Following the PRISMA methodology, systematic searches in different scientific databases identified 17 studies, revealing that burnout is related to age, personality traits, and type of priesthood. No relation between burnout and social support, self-care, spiritual practice, or workload was detected. It is necessary to adapt conceptual models to the peculiarities of burnout among clergy, extending assessment strategies and introducing working and organizational perspectives in the analysis of modulating variables, and in the development of prevention and intervention programs.

Macrolitter and microplastics along the East Pacific coasts - A homemade problem needing local solutions

The East Pacific (EP) region, especially the central and southern EP, has been fairly less studied than other world's regions with respect to marine litter pollution. This comprehensive literature review (257 peer-reviewed publications) showed that both macrolitter (mostly plastics) and microplastics tend to accumulate on EP shorelines. Moreover, they were also reported in all the other compartments investigated: sea surface, water column, seafloor and 'others'. Mostly local, land-based sources (e.g., tourism, poor waste management) were identified across the region, especially at continental sites from low and mid latitudes. Some sea-based sources (e.g., fisheries, long-distance drifting) were also identified at high latitudes and on oceanic islands, likely enhanced by the oceanographic dynamics of the EP that affect transport of floating litter. Our results suggest that effective solutions to the problem require local and preventive strategies to significantly reduce the levels of litter along the EP coasts.
