The Influence of Altitude, Urbanization, and Local Vaccination Centers on Vaccine Uptake within an Italian Health District: An Analysis of 15,000 Individuals Eligible for Vaccination.

In Italy, free vaccinations for Herpes Zoster (HZ), pneumococcal (PCV), and influenza (FLU) are recommended each year for individuals turning 65. Despite this, achieving optimal vaccination coverage remains challenging. This study assesses coverage rates for HZ, PCV, and FLU in Forlì, Northern Italy, and examines how altitude, urban planning, and health organization variables (such as the presence of a vaccination center) impact vaccine uptake. Vaccination coverages were calculated for birth cohorts between 1952 and 1958 for each municipality in the Forlì area as of 1 March 2024. The geographical factors influencing the vaccination uptake were extracted from the Italian National Institute of Statistics (ISTAT) records and evaluated through a multivariate analysis. The sample analyzed included 15,272 vaccine campaign targets from Forlì's province (185,525 citizens); the vaccine uptake rates for HZ, PCV, and FLU were 26.9%, 36.7%, and 43.5%, respectively. Gender did not appear to influence vaccine uptake. Living in a flat area appeared to increase vaccine uptake in a statistically significant way for all the vaccinations when compared to a mountainous area (HZ: OR: 1.50, PCV: OR: 1.33, FLU: OR: 1.67). The presence of a vaccine service in low-urbanized areas was shown to increase vaccine uptake for all vaccinations (HZ: OR: 1.65, PCV: OR: 1.93, FLU: OR: 1.53) compared with low-urbanized areas without a vaccination center or more urbanized areas with a vaccination center. This study emphasizes the significance of the territorial context, along with the ease of access to vaccinations and geographic barriers, as key determinants in achieving vaccination targets. Local health authorities should consider these factors when implementing vaccination campaigns.

Synergistic patient factors are driving recent increased pediatric urgent care demand.

We aimed to use the high fidelity urgent care patient data to model the factors that have led to the increased demand at our local pediatric urgent care centre. The dataset for this retrospective cohort study was obtained from our local healthcare centre's national reporting data for pediatric urgent care visits from 2006 to 2022. Variables analyzed included: basic patient demographics, chief complaint, triage urgency, date and time of registration/discharge, discharge diagnosis, and discharge destination. Statistical analysis of non-linear trends was summarized by locally estimated scatterplot smoothing splines. For machine learning, we used the tidymodels R package. Models were validated in training using k-fold cross validation with k = 5. We used univariate linear regression as a baseline model. After the data was standardized, correlation and homoscedasticity were evaluated between all parameter permutations. This dataset consisted of 164,660 unique visits to our academic centre's pediatric urgent care. Over the study period, there was an overall substantial increase in the number of urgent care visits per day, with a rapid increase beyond previous levels in 2021 and further in 2022. The increased length of stay trend was consistent across presenting complaint categories. The proportion of patients without primary care in 2022 was 2.5 times higher than in 2013. A random forest machine learning model revealed the relative importance of features to predicting a visit in 2022 were: longer stay, later registration in the day, diagnosis of an infectious illness, and younger age. This study identified a combination of declining primary care access, circulating viral infections, and shifting chief complaints as factors driving the recent increase in frequency and duration of visits to our urgent care service.

The utilization of mapping to improve the quality of community development in rural areas

Selayar Regency occupies the sixth position for stunting in South Sulawesi, with a prevalence of 32.1%. This problem is exacerbated by the community's limited access to information about stunting, so educational efforts are needed to disseminate stunting information presented using spatial mapping patterns. This activity aimed to develop village maps and identify high-stunting areas using spatial maps to improve the quality of community development. This map-making activity begins with data collection, and then data processing is carried out using ArcGIS software, digitization methods, and spatial analysis in the form of overlay analysis. Maps that have gone through the layout stage are then printed and submitted to the village government and health workers. The utilization of this map of strategic locations such as village offices, health centers, and local nutrition centers assesses the success of this services activity as a source of information in determining priority steps in preventing and handling stunting cases.

Assessing Blood Donors' Knowledge, Attitudes, and Practices Regarding Blood Donation - A Cross-Sectional Study

<i>Introduction: </i>Blood donation is vital for saving lives in critical medical conditions, making it a global concern. Ensuring a stable blood supply is essential for emergency treatments, surgeries, and chronic disease therapies. Blood donors, including influential figures like imams, play a critical role in promoting and normalizing blood donation within communities. <i>Aim of the study: </i>The aim of this study was to assess the knowledge, attitude and practices of blood donors toward blood donation. <i>Methods: </i>This cross-sectional study at Imam Training Academy of the Islamic Foundation, Bangladesh, included 200 Imams aged 18 above. Conducted from February 2023 to January 2024, data on knowledge, attitudes, and practices were collected through face-to-face interviews using a semi-structured questionnaire. Statistical analysis was performed with SPSS Version 26, considering a P-value of <0.05 as significant. Ethical clearance was obtained from the local ethical committee. <i>Result: </i>The study findings indicate that the majority (61.5%) of participants were aged between 20-29 years, with 19.5% aged 30-39 years. Awareness about blood donation was moderate, with 45% aware of their blood group and Rh factor. Most participants (83.5%) understood that receiving infected blood can transmit diseases, and 65% correctly identified the interval for safe blood donation. Knowledge of local blood transfusion centers beyond BSMMU was low at 36%. Attitudes toward blood donation were overwhelmingly positive, with high agreement that donation saves lives (96.5%) and is a moral activity (97.5%). The preference for voluntary non-remunerated donation was unanimous (98%). However, only 35% of respondents had donated blood at least once, with 33.5% donating voluntarily. <i>Conclusion:</i> The study found that blood donors had good knowledge and a positive attitude toward blood donation. However, most individuals were not donating blood regularly as volunteers.

Social Justice in Community Environments: A Collaborative Photovoice Process

A small New England University and a local community center undertook a community based participatory research approach to understand the community-driven factors that most impact health. Photovoice was utilized to collaboratively highlight priority issues and to collectively advocate for change. The Photovoice approach was particularly useful in this context to transcend language differences and foster community dialogue between community and institutional partners in a way that dismantled traditional — and historically harmful — power dynamics between institutions and communities. The goal of utilizing this participatory-based method was to support community-identified social-ecological change, advocate for identified environmental justice priority issues, and support sustained community involvement. The novel aspects of the approach included guiding students and community members through this process in a community-engaged learning context that brought together linguistically diverse populations with a foundation of cultural humility, respect, and multi-directional learning.

Type 2 Diabetes and Risk Factors in an Adult Population in Oujda, Eastern Morocco: A Cross-Sectional Observational Study.

Objectives The rapidly increasing prevalence of diabetes makes it a public health concern. Adopting a healthier lifestyle can prevent or delay the onset of type 2 diabetes (T2D), the most common type of diabetes, and its complications. The aim of this study is to determine the prevalence of diabetes at the level of local health centers in the prefecture of Oujda, Morocco, and its relationship with obesity, physical activity, and sociodemographic factors. Methodology In a cross-sectional study in first-line health centers, sociodemographic and bioclinical data were collected through convenient purposive sampling using anthropometric and blood glucose measurements and structured, comprehensible interview questionnaires. The International Physical Activity Questionnaire (IPAQ) questionnaire was used to measure the physical activity of the patients. The association of T2D with age, gender, education, occupation, obesity, and physical activity was analyzed. Results Out of 535 observed patients, 510 were included, mostly female with a minimum age of 18 years, with a prevalence of T2D of 16%. More than half of the patients were illiterate (56%) and 83% had no occupation. Obesity was prevalent, especially among diabetics, and only a minority were physically active according to WHO targets. Thirty-six percent of all patients and 46% of diabetics reported low levels of physical activity. Age and obesity were the main factors associated with T2D. Conclusion Obesity and T2D have a high prevalence in the Oujda region. A balanced diet and regular physical activity remain our best recommendations for preventing this disease. Special attention should be paid to women with diabetes in Arab countriesso that they can actively participate in prevention activities.

Evaluating Intelligent CPTED Systems to Support Crime Prevention Decision-Making in Municipal Control Centers

To maximize its synergetic effect across the cycle from prevention to response to post-crime management, crime prevention requires a balanced combination of spatial urban design and advanced crime prevention technologies for crime prediction and real-time response. This study derived intelligent Crime Prevention Through Environmental Design (CPTED) services and suggested a decision model based on the fuzzy Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to implement these services in municipal control centers. The analysis results are summarized as follows. First, this study established a fuzzy TOPSIS-based decision-making support model enabling local government control centers to effectively select intelligent CPTED service elements. Second, overall, operator-led Closed-Circuit Television (CCTV) and platform control technologies were identified as significant components of intelligent CPTED service elements. Third, a comparison by city size revealed that large cities in the Seoul metropolitan area rated system services for control based on advanced crime prevention infrastructure (e.g., the crime monitoring systems and real-time control drones/robots) relatively higher. In contrast, small and medium-sized cities in other provinces rated services that were perceptible to residents and improved crime-prone environments (e.g., artificial intelligence (AI) video analysis for living safety) relatively higher.

Matryoshka: Exploiting the Over-Parametrization of Deep Learning Models for Covert Data Transmission.

High-quality private machine learning (ML) data stored in local data centers becomes a key competitive factor for AI corporations. In this paper, we present a novel insider attack called Matryoshka to reveal the possibility of breaking the privacy of ML data even with no exposed interface. Our attack employs a scheduled-to-publish DNN model as a carrier model for covert transmission of secret models which memorize the information of private ML data that otherwise has no interface to the outsider. At the core of our attack, we present a novel parameter sharing approach which exploits the learning capacity of the carrier model for information hiding. Our approach simultaneously achieves: (i) High Capacity - With almost no utility loss of the carrier model, Matryoshka can transmit over 10,000 real-world data samples within a carrier model which has 220× less parameters than the total size of the stolen data, and simultaneously transmit multiple heterogeneous datasets or models within a single carrier model under a trivial distortion rate, neither of which can be done with existing steganography techniques; (ii) Decoding Efficiency - once downloading the published carrier model, an outside colluder can exclusively decode the hidden models from the carrier model with only several integer secrets and the knowledge of the hidden model architecture; (iii) Effectiveness - Moreover, almost all the recovered models either have similar performance as if it is trained independently on the private data, or can be further used to extract memorized raw training data with low error; (iv) Robustness - Information redundancy is naturally implemented to achieve resilience against common post-processing techniques on the carrier before its publishing; (v) Covertness - A model inspector with different levels of prior knowledge could hardly differentiate a carrier model from a normal model.

Project Vayoraksha: Implementation of novel mHealth technology for healthcare delivery during COVID-19 in geriatric population of Kerala.

Background & objectives mHealth technologies, with their potential in improving public health, have recently gained considerable interest in India, offering an opportunity to deliver tailored and low cost interventions to the selected populations, especially in resource-poor settings. Project Vayoraksha aimed at developing and pilot testing mHealth technology-assisted strategies (Vayoraksha mobile application and field Vayoraksha network) to improve healthcare delivery and reverse quarantine at the field level among the geriatric population. Methods This field operational research study was implemented in Pathanamthitta, Kerala, from October 2020 to July 2021. The Vayoraksha mobile phone application for the geriatric users and a web interface used by healthcare workers involved in the field Vayoraksha network was developed with multisectoral expertise. Vayoraksha had facilities for symptom surveillance, teleconsultation and assessment of needs and included a community-based system to monitor and meet their needs that can help in reverse quarantine of the geriatric population. Results The project was implemented using the field Vayoraksha campaign involving frontline health workers and community volunteers. A baseline survey of 4782 geriatric population in the study area was conducted in Phase I, and 2383 (49.8%) had access to a smartphone facility to use Vayoraksha. Of these, 1257 (52.7%) were covered under the 'field Vayoraksha campaign' using intersectoral coordination and community participation. A total of 750 (59.6%) geriatric individuals downloaded the application of whom, 452 (60.3%) used the services of Vayoraksha. Needs were registered by 56 (12.3%) individuals of which 46 (82.1%) were medical needs related to the management of chronic diseases. More than 70 per cent of the needs were met through the Vayoraksha field network under the local primary health centre. More than 80 per cent of the geriatric individuals reported symptoms related to COVID-19 during the intervention period. Compliance with quarantine was observed in 77.7 per cent of the geriatric populations. Among those who used Vayoraksha, 26 (5.7%) availed tele-counselling services, and 3 (0.6%) used teleconsultation facilities. It was observed that Vayoraksha users had a higher proportion of the geriatric population who were young, educated, having chronic morbidity and living with family. Regular symptom surveillance was done within this group; only 12 (2.6%) of them tested positive for COVID-19 during this study. Interpretation & conclusions Results of this pilot study are promising, with 60 per cent of the geriatric population downloading and using Vayoraksha within a short time. Technology-assisted interventions can supplement the existing system for improved healthcare delivery among the vulnerable groups and have good potential for scale-up in the near future in developing countries.

Fertility preservation service for children and young adults at high risk of infertility; the hub and spoke model

PurposeTo evaluate the evolution of fertility preservation surgery in children and young adults at high risk of infertility from a single centre to a networked ‘Hub and Spoke’ service.MethodsA case note review of patients referred for ovarian or testicular cryopreservation between Jan 2013 and Dec 2023. Demographic data, procurement numbers, and site of procurement were collected. Specialist feedback was obtained to identify the challenges faced.ResultsOver time, the number of referrals increased from 4 to 349 patients per year with the number of Spoke centres rising to 36 ovarian and 16 testicular. In 2013–2014; 100% of procurement was ovarian as compared to 2023; 51% ovarian, 49% testicular. Of the 395 referrals in 2021, 81% (n = 319) went on to have procurement and storage of tissue. Between 2013 and 2016, 96% of cases were performed at the Hub. In 2023, 53/349 (15%) cases were performed at the Hub with the remaining 296 (85%) procured at Spoke sites. Surgical issues such as access to theatre, variation and availability of surgical equipment, thermal injury to ovarian tissue and variation in the size of the testicular specimen were identified.ConclusionThe Hub and Spoke model successfully delivers treatment to patients close to home as safely possible within their local treatment centre.

Use of HBsAg-positive donors in liver transplantation: An ILTS-EASL-AASLD multisociety survey.

The gap between organ supply and demand in liver transplantation remains large in most parts of the world. One strategy to increase the donor pool is to use grafts infected with HCV, HBV, and/or HIV viruses. We aimed to explore the current use of HBsAg-positive liver grafts worldwide. A prospective cross-sectional web-based survey was designed, with a total of 28 queries, assessing national and local regulations, center experience, and center-specific experience related to the topic, and sent to all members of International Liver Transplantation Society, European Association for the Study of the Liver, and American Association for the Study of the Liver, and promoted on social media. A total of 135 liver transplant centers answered the survey: 38% from WHO European Regions, 39% from American regions, and 9.7% from South-East Asian regions. Most of the participating centers (67.3%) had been performing liver transplantation for over 15 years, with a mean of 66.5 liver transplants per year, and 54% also performed living-donor liver transplants. HBV-related disease was the indication for liver transplantation in an average of 15% of all liver transplantation cases. Regarding national and/or regional regulations, 40% of the centers reported that the use of HBsAg-positive donors was permitted, and an additional 20% could use them under special circumstances. Thirty-two centers (31%) had previously used HBsAg-positive donors. Among these centers, 62.5% conducted living-donor liver transplants and showed an increased inclination towards the use of HBsAg-positive grafts in centers with elevated waitlist mortality. HBsAg-positive donors are underutilized worldwide. The use of HBsAg-positive liver grafts could help to increase the donor pool, particularly in highly endemic areas.

Questionnaire survey on cervical cancer screening and HPV awareness among patients at a local cancer center in Japan

BackgroundThe incidence of cervical intraepithelial neoplasia is increasing in Japan. Although human papillomavirus (HPV) vaccination and cancer screening are crucial in preventing cancer-related mortality, the cervical cancer screening rate in Japan was only approximately 43.6% in 2022. This study aimed to conduct an epidemiological analysis of cervical cancer by collecting data from individual patients.MethodsA questionnaire survey was administered to patients who visited our hospital between January 2017 and July 2023 owing to abnormal cervical cytological findings or a cancer diagnosis. Patients answered questions regarding their history of cervical cancer screening as well as their knowledge of HPV and cervical cancer.ResultsDuring the study period, 471 patients participated in the survey, with 35 declining to participate. Patients with Stage 1b1–4b primarily sought medical attention due to self-reported symptoms (P < 0.001); however, they were less likely to have undergone cervical cancer screening (P < 0.001). Additionally, older patients were less likely to be aware of the association of HPV with cervical and other cancers. Notably, 28 of the 129 patients with stage 1b1–4b cancer underwent cervical cancer screening within 2 years. The tumor location within the endocervical canal emerged as a significant factor contributing to the difficulty for an accurate diagnosis of precancerous or cervical cancer during cervical screening. Furthermore, non- squamous cell carcinoma (SCC) histology was another possible factor.ConclusionsOur findings suggest the need to widely disseminate information regarding the significance of cancer screening to increase cancer screening rates. Moreover, establishing strategies for improving the accuracy of detecting lesions during screening for non-SCC and endocervical canal tumors is crucial.

Photoluminescence probing of light absorption centers at silica laser damage

We use photoluminescence (PL) imaging to study damage growth precursors within laser damage sites on the surface of silica. Damage site evolution is induced by multiple shots of UV nanosecond pulsed laser at various energy densities and monitored throughout the early stages of growth. Wide-field PL imaging rapidly locates microscopic light absorption centers within the silica damage site. Our quantitative analysis shows that damage sites with strong local PL intensity show a higher probability of growth upon subsequent laser pulses. Scanning electron microscopy (SEM) paired with a study of PL spectrum shows that the strong PL intensity appears from the subsurface fractures with high defect density, which provides a local light absorption center leading to significant damage growth. We believe that this result offers an efficient optical damage mitigation strategy by providing a rapid and non-destructive optical inspection approach.

Unraveling the nature of local field distortion-induced dual electron-trapping centers for efficient photocatalytic fuel evolution

Active electron-trapping centers play significant roles in photocatalysis. Herein, we synergize local field distortion and defects in nanocrystals to produce dual electron-trapping centers and unravel the nature of aluminum doping in porous ZnO with tunable amounts of heteroatoms and oxygen vacancies. The introduced Al atoms in the structural domain induce local field distortion and trigger the movement of Zn2+ from a singlet low spin state to a stable triplet state, resulting in the generation of free carriers trapping centers and optimized electronic energy band structure. Dual active electron-trapping centers of heteroatoms and oxygen vacancies promote the Separation of photo-generated charge carriers and reduce the adsorption energies of H* species. Furthermore, the d-band center of Al-doped ZnO with oxygen vacancies shifts to a higher energy position, thus promoting the adsorption and desorption of hydrogen intermediates and exhibiting 4-fold the photocatalytic H2 efficiency of pristine ZnO. This study provides new insights into the rational design of highly efficient oxide-based photocatalysts toward sustainable solar fuel evolution.

The Association Between Energy Adequacy Level And Physical Activity With Nutri-tional Status In Adolescents At Walisongo High School, Ketanggungan

Growth during adolescence is rapid due to the development of muscle mass and fat tissue as well as hormonal changes that affect the nutritional needs of adolescents. The purpose of this study was to determine how the nutritional status of adolescents and the level of energy adequacy and physical activity relate to each other. This type of research uses a cross-sectional design. The number of samples taken with simple random sampling technique in this study was 152 people. Data collection of energy adequacy level using SQ-FFQ, physical activity data with PAL questionnaire, and nutritional status of respondents obtained from measurements of BW and TB. The results showed that most participants had an adequate level of energy sufficiency (65.1%) according to the Spearman Rank test, physical activity was mostly in the moderate category (63.8%), and the majority had good nutritional status (80.9%). The results of the Spearman Rank test showed that there was a significant correlation between the level of energy adequacy and nutritional status (p value = 0.045) and there was a significant correlation between physical activity and nutritional status (p value = 0.021). The conclusion is that there is a significant correlation between the level of energy adequacy and physical activity with nutritional status in adolescents at Walisongo Ketanggungan High School. It is recommended for the school to collaborate with the health department or local health center to make preventive and promotive efforts related to nutritional status problems through education about General Guidelines for Balanced Nutrition (PUGS).

699 Gender Inequality in Orthopaedic Radiation Protection: An Audit

Abstract Aim The literature demonstrates an increased prevalence of breast cancer in female orthopaedic surgeons compared to the population baseline. One contributor to this alarming statistic may be exposure to frequent low-dose radiation inherent to orthopaedics. The British Orthopaedic Association (BOA) has emphasised the importance of wearing lead aprons that provide adequate coverage, especially of the axillary region in women. To assess the availability of vests that fulfil such criteria, an audit of the lead aprons available at our local adult tertiary centre was undertaken. Method Lead protective equipment used by the orthopaedic theatres were documented by type, size, and brand. Data collection occurred prior to theatre activity requiring lead use, to ensure all equipment was present. Results 115 pieces of equipment were identified - 43 standard vests, 9 tabard gowns with side coverage, 4 tabard gowns without side coverage, 48 skirts and 11 thyroid covers. Vests, skirts, and tabard gowns ranged from XS (n=4), S (n=21), M (n=15), L (n=46), to XL (n=12), unidentifiable size (n=6). Vests, skirts and tabard gowns ranged from several different brands including Xenolite Male (n=45), Xenolite Female (n=29) and Kenex (n=23). No boleros, high axilla vests, or vests with wings/sleeves/axillary shields, were identified. Conclusions This audit demonstrated inadequate adherence to BOA recommendations and a lack of size diversity. With increasing numbers of women in orthopaedics, there is a need to raise more awareness and address this safety concern to mitigate a larger concerning trend.

Sure as the sunrise: insights into the material culture of Albion Motors from Glasgow Life’s museums and archives collection

ABSTRACT Albion Motors Ltd was a large company based in Scotstoun, Glasgow, employing thousands over its nine-decades existence. Much is known about its manufacturing output of cars, lorries, and buses, so the purpose of this research was to investigate Albion-related archive material held by Glasgow Life and consider this within a social historic context. The paper is replete with evidence of the human experience of the company, obtained through various research methods including scrutiny of primary source material, site visits, and unstructured in-person and telephone interviews. Whilst containing some inconclusive elements, the personal testimony of one former employee, which so effectively brought the past to life, was a poignant reminder to continue this research. Thankfully, the local community centre in Scotstoun had a similar idea, to host an open day for former staff to share memories of working for Albion – proving there are many anecdotes yet to document.

Should Only Popular Products Be Stocked? Warehouse Assortment Selection for E-Commerce Companies

Problem definition: This paper studies the single-warehouse assortment selection problem that aims to minimize the order fulfillment cost under the cardinality constraint. We propose two fulfillment-related cost functions corresponding to spillover fulfillment and order splitting. This problem includes the fill rate maximization problem as a special case. We show that although the objective function is submodular for a broad class of cost functions, the fill rate maximization problem with the largest order size being two is NP-hard. Methodology/results: To make the problem tractable to solve, we formulate the general warehouse assortment problem under the two types of cost functions as mixed integer linear programs (MILPs). We also provide a dynamic programming algorithm to solve the problem in polynomial time if orders are nonoverlapping. Furthermore, we propose a simple heuristic called the marginal choice indexing (MCI) policy that allows the warehouse to store the most popular products. This policy is easy to compute, and hence, it is scalable to large-size problems. Although the performance of MCI can be arbitrarily bad in some extreme scenarios, we find a general condition under which it is optimal. This condition is satisfied by many multi-purchase choice models. Managerial implications: Through extensive numerical experiments on a real-world data set from RiRiShun Logistics, we find that the MCI policy is surprisingly near optimal in all the settings we tested. Simply applying the MCI policy, the fill rate is estimated to improve by 9.18% on average compared with the current practice for the local transfer centers on the training data set. More surprisingly, the MCI policy outperforms the MILP optimal solution in 14 of 25 cases on the test data set, illustrating its robustness against demand fluctuations.
