han half of children in the family (68%) were ≤ 4. The findings showed that children whose mothers had no formal education were 2.59 times more likely to die than children whose mothers had formal education [AOR 2.59(1.12-5.99)]. Similarly, children who did not receive breastfeeding from their mothers were 3.61 times more likely to die than children who received breastfeeding from their mothers [AOR 3.61(1.83-6.19)]. CONCLUSION AND RECOMMENDATION The number of children in the family, as well as the mother's educational status and current breastfeeding status, were all found to be important factors in under-five mortality in the study area. As a result, the potential determinants of under-five mortality should be addressed as part of a program targeted at lowering childhood mortality.
The relationship between nurse staffing levels and patient safety is well recognised. Inadequate provision of nursing staff is associated with increased medical error, as well as higher morbidity and mortality. Defining what constitutes safe nurse staffing levels is complex. A range of guidance and planning tools are available to inform staffing decisions. The Society for Acute Medicine (SAM) recommend a 'nurse-to-bed'ratio of greater than 16. Whether this standard accurately reflects the pattern and intensity of work on the Acute Medical Unit (AMU) is unclear.

Nurse staffing levels in AMUs were explored using the Society for Acute Medicine Benchmarking Audit 2019 (SAMBA19). Data from 122 acute hospitals were analysed. Nurse-to-bed ratios were calculated and compared. Estimates of the total nursing time available within the acute care system were compared to estimates of the time required to perform nursing activities.

The total number of AMU beds across all 122 units was 4997. The mean daytime nurse-tommenced SAM staffing levels, particularly at night. A difference was observed between the total number of nursing hours within the acute care system and the estimated time required to perform direct nursing activities. This suggests a workforce shortage of nurses within acute care at the system level.
The Gulf Cooperation Council (GCC) countries relied, until recently, solely on import duties for tobacco products. The agreement for the introduction of an excise and value added tax (VAT) in 2016 and 2017, respectively, in most GCC countries, was a major breakthrough for public health. There is, however, ample room for improvement.

The study examines the outcomes of tax reforms, for both public health and public finances, based on the World Health Organization (WHO) recommendations and best practices worldwide. Tax simulations were performed using the WHO TaXSiM model. The study is based on data from Saudi Arabia, the only GCC country for which sufficient data existed.

We recommend a stepwise tax reform, which involves increasing the current ad valorem excise tax rate, phasing out import duties keeping total tax share constant and introducing a minimum excise, and finally switching to a revenue-neutral specific excise. Specific excises must be adjusted for inflation and income increases. If implementedo monitor and advance public health.
Several studies have assessed the relationship between type 2 diabetes (T2D) and tooth loss; however, results have been inconsistent. Therefore, the present systematic review and meta-analysis of observational studies was designed to examine the association between T2D and tooth loss.

This systematic review and meta-analysis was conducted based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Guideline. We searched all the relevant studies in international databases of Scopus, PubMed, ProQuest, Web of Science, Cochrane Library, and Google scholar search engine until February 2022. The heterogeneity of the studies was calculated using the I
index. Measure of effect and 95% confidence interval (CI) were extracted from each study. The results of the study were analyzed using the random effects model.

In the present study, 22 eligible studies were included. Meta-analysis of unadjusted and adjusted results showed that T2D significantly increased the risk of tooth loss, and Odds Ratio (OR) unadjusted was 1.87 (95% CI 1.62-2.13, p < 0.001), and OR adjusted was 1.20 (95% CI 1.10-1.30, p < 0.001), respectively. Subgroup analysis based on study design for adjusted OR indicated that in the cohort study (OR 1.29, 95% CI 1.07-1.51), in the cross-sectional study (OR 1.15, 95% CI 1.06-1.23), and in the case-control study (OR 5.10, 95% CI 1.01-9.18) there was a significant association between T2D and tooth loss. Other subgroups analyses showed consistent results and no publication bias existed.

The findings suggest that T2D is associated with increased risk of tooth loss. This conclusion may provide useful evidence for correlated clinical researches.

Intimate partner violence (IPV) during pregnancy is significantly associated with negative outcomes for both mother and child. Current evidence indicates an association between low levels of social support and IPV, however there is less evidence from low-and-middle income countries (LMIC) than high-income countries. Globally, the COVID-19 pandemic has radically altered how women can access social support. Hence since 2020, studies investigating IPV and pregnancy have occurred within the changing social context of the pandemic.

This scoping review summarizes the evidence from LMICs about the effects of IPV during pregnancy on maternal and child health. The review includes the impact of the COVID-19 pandemic on social support as mentioned in studies conducted since 2020.

Library databases were used to identify papers from 2016 to 2021. These studies reported the maternal and child health outcomes of IPV during pregnancy, and described how social support during pregnancy, and the COVID-19 pandemic, were asder range of outcomes. To date, there is limited evidence on the impact of the COVID-19 pandemic on IPV during pregnancy in LMICs, and this should be prioritized as the pandemic continues to affect women's access to social support globally.
Further research on the impact of IPV during pregnancy on maternal and child outcomes in LMICs is required, especially evidence from longitudinal studies investigating a wider range of outcomes. learn more To date, there is limited evidence on the impact of the COVID-19 pandemic on IPV during pregnancy in LMICs, and this should be prioritized as the pandemic continues to affect women's access to social support globally.
Limited evidence is available about the combination of multiple smoking cessation modalities in low- and middle-income countries. The study aimed to assess the feasibility of a smoking cessation intervention that integrates follow-up counselling phone calls and scheduled text messages with brief advice from physicians in Vietnam.

This was a single-arm intervention study. Smokers were referred to the study Quitline after brief advice by physicians at three rural district hospitals in Hanoi, Vietnam. Following referral, participants received nine counselling phone calls in 12months and a scheduled text message service that lasted for three months. Participants who reported smoking cessation for at least 30days at the 12-month follow-up were invited for a urinary cotinine test to confirm cessation.

The Quitline centre had 431 referrals from participating hospitals. Among them, 221 (51.3%) were enrolled. After the baseline phone call, 141 (63.8%) participated in all 4 follow-up calls within the first month and 117 (52.9%) participated in all phone calls in 12months. The median number of successful phone calls was 8 (interquartile range 6 - 8). At the end of the study, 90 (40.7%) self-reported abstinence from smoking over the previous 30days. Among them, 22 (24.4%) submitted a sample for cotinine test, of which 13 (59.1% of those tested) returned a negative result. The proportion of biochemically-verified quitters was 5.9%.

The integration of brief advice and referral from healthcare facilities, Quitline counselling phone calls, and scheduled text messaging was feasible in rural health facilities in northern Vietnam.

Transfer learning (TL) with convolutional neural networks aims to improve performances on a new task by leveraging the knowledge of similar tasks learned in advance. It has made a major contribution to medical image analysis as it overcomes the data scarcity problem as well as it saves time and hardware resources. However, transfer learning has been arbitrarily configured in the majority of studies. This review paper attempts to provide guidance for selecting a model and TL approaches for the medical image classification task.

425 peer-reviewed articles were retrieved from two databases, PubMed and Web of Science, published in English, up until December 31, 2020. Articles were assessed by two independent reviewers, with the aid of a third reviewer in the case of discrepancies. We followed the PRISMA guidelines for the paper selection and 121 studies were regarded as eligible for the scope of this review. We investigated articles focused on selecting backbone models and TL approaches including feature extr studies demonstrated the efficacy of transfer learning despite the data scarcity. We encourage data scientists and practitioners to use deep models (e.g. ResNet or Inception) as feature extractors, which can save computational costs and time without degrading the predictive power.
Pediatric integrative medicine, combining conventional and complementary medical approaches for children and adolescents, is an integral part of the health care system in Switzerland. However, there is still a lack of complementary and integrative medicine topics in training and continuing educational programs. For the first time on a national level, the 2021 annual conference of the Swiss Society of Pediatrics was entirely dedicated to the topic of integrative medicine.

Using a cross-sectional online survey, this study investigated congress participants' evaluation and feedback with the aim to assess whether the program had met their objectives and to get empirical data on their attitude, expectations and needs regarding pediatric complementary and integrative medicine. Descriptive methods were used to present the results.

Among 632 participants of the conference, 228 completed the evaluation form (response rate 36%). The overall feedback about the congress and the main theme of pediatric integrative mg and continuing medical education based on evaluations of participant feedback can promote professional development and improve patient care for the benefit of physicians and patients.
Cancer of Unknown Primary (CUP) is a metastatic cancer for which the primary lesion remains unidentifiable during life and little is also known about the modifiable risk factors that contribute to its development. This study investigates whether vegetables and fruits are associated with CUP risk.

We used data from the prospective Netherlands Cohort Study on Diet and Cancer which includes 120,852 participants aged between 55 and 69 years in 1986. All participants completed a self-administered questionnaire on cancer risk factors at baseline. Cancer follow-up was established through record linkage to the Netherlands Cancer Registry and the Dutch Pathology Registry. As a result, 867 incident CUP cases and 4005 subcohort members were available for case-cohort analyses after 20.3 years of follow-up. Multivariable adjusted hazard ratios were calculated using proportional hazards models.

We observed no associations between total vegetable and fruit consumption (combined or as separate groups) and CUP risk. However, there appeared to be an inverse association between the consumption of raw leafy vegetables and CUP.
