Educating Japanese elementary students on proper smartphone use and social media risks: Reflecting on post-COVID-19 crime trends.

Smartphone ownership and social media use are increasing worldwide, and children are not exempt from these trends. Past studies on this issue have mainly focused on educational campaigns to prevent the prolonged use of smartphones, social media, and video games. Recently, harm to children from engagement with bad actors through social media has become a major problem in Japan, and preventive measures need to be based on close analysis of the facts. The present study was performed descriptive epidemiology and comparison between two groups. This study investigated the number of children in Japan who fell victim to criminal offense through their use of social media, categorized by level of schooling, type of offense, and means of accessing social media over the 8-year period from 2016 to 2023. The 8-year period was divided into 2016-2019 (4 years prior to the COVID-19 pandemic) and 2020-2023 (4 years during the pandemic). Statistical analysis was conducted to compare these periods. The number of elementary school students victimized by criminal offense through social media in Japan increased significantly in 4 years during the pandemic. Furthermore, in 4 years during the pandemic, there was also a notable rise in felony-related incidents, and an increase in the number of victims accessing social media via smartphones. Schools, parents/guardians, and personnel and organizations in relevant fields need to collaborate in addressing and educating students about the proper use of smartphones and the risks of social media starting at the elementary school age.

Accuracy of geometric morphometrics for age estimation using frontal face photographs of children and adolescents: A promising method for forensic practice.

Age estimation is crucial in legal and humanitarian contexts. Forensic professionals may use various procedures to estimate age, including dental analysis, bone density tests, evaluation of physical characteristics including facial bone structure and development, and image-based methods. Although images are often the only material available, visual observation of photographic material is an imprecise method in age estimation, which can compromise judicial decision-making. Analyzing 4000 photographs from the Brazilian Federal Police database, representing four age groups (6, 10, 14, and 18 years), the study employed automated analysis by marking 28 photogrammetric points. Data were used to establish facial patterns by age and sex using the facial geometric morphometrics method. Performance was assessed through a Multinomial Logistic Regression model, evaluating accuracy, sensitivity, and specificity across the categorical age groups. Analyses were conducted using R software, with a 5 % significance level. The study found that facial geometric morphometrics achieved an overall accuracy of 69.3 % in age discrimination, with higher accuracy in males (74.7 %) compared to females (65.8 %) (p < 0.001). The method excelled at predicting the age of 6-year-olds with 87.3 % sensitivity and 95.6 % specificity but had lower performance at 14 years. It showed greater accuracy in distinguishing age groups with larger age gaps, achieving up to 99.5 % accuracy between certain groups, and was particularly effective in differentiating ages of 6 and 10 years in females and 10, 14, and 18 years in males. The facial geometric morphometrics emerges as a promising approach for age estimation among children and adolescents in forensic settings.

IVF and obstetric outcomes among women of advanced maternal age (≥45 years) using donor eggs.

RESEARCH QUESTION: Does very advanced maternal age (VAMA; age ≥45 years) influence obstetric outcomes among women using donor oocytes in IVF? DESIGN: This retrospective cohort study analysed data from a nationwide IVF registry in Taiwan, focusing on IVF cycles involving women aged 45 years and older using donated oocytes between 2007 and 2016. The study assessed cumulative live birth rates (CLBR) and secondary outcomes such as clinical pregnancy, miscarriage, live birth and twin pregnancy rates, alongside perinatal outcomes such as Caesarean section rates, pre-eclampsia, gestational diabetes and birthweight. RESULTS: The study included 1226 embryo transfer cycles from 745 women, with a stable live birth rate of about 40% across the study period. The CLBR was slightly lower in women aged 50 years and older (54.2%) compared with those aged 45-46 years (58.0%), but these differences were not statistically significant (P = 0.647). Secondary outcomes and perinatal outcomes did not significantly differ across age groups. Regression analysis suggested a non-significant trend towards a decrease in live birth rate and birthweight with increasing maternal age. The study also found that single-embryo transfer (SET) minimized the risk of twin pregnancies without significantly affecting live birth rates. CONCLUSIONS: IVF with donor oocytes remains a viable option for women of VAMA, with consistent live birth rates across age groups. However, the study underscores the importance of elective SET to reduce the risk of twin pregnancies and associated adverse outcomes. Further research is needed to explore the impact of other factors such as paternal age and embryo development stage on IVF success in this population.

High threshold of total developmental quotient at 3 years for follow-up in extremely preterm infants.

AIM: To investigate the relationship between the developmental quotient (DQ) at age 3 years and the need for educational support at school age in extremely preterm infants. METHODS: A total of 176 infants with a gestational age of <28 weeks were analyzed. The total DQ and subscales were evaluated using the Kyoto Scale of Psychological Development (KSPD) test. Neurodevelopment at age 3 years was stratified using total DQ in a conventional (DQ < 70 as developmental delay, DQ 70- <85 as subnormal, DQ ≥85 as normal) and a modified way (subdividing normal into DQ 85- <93 as low-normal and DQ ≥93 as high-normal). The prevalence of future educational support was compared for each stratum. Additionally, subscales were compared between those with and without educational support in each total DQ stratum. RESULTS: In conventional stratification, the prevalence of educational support was 32 (63 %) for developmental delay, 14 (24 %) for subnormal, and 10 (15 %) for normal. In modified stratification, the prevalence was 8 (26 %) for low-normal and 2 (5 %) for high-normal. While there was no significant difference in the odds of educational support between the normal and subnormal, the low-normal had significantly higher odds compared to the high-normal (OR 6.00; 95 % CI, 1.16-30.95, p = 0.03). Among the low-normal stratum, the language-social subscale was significantly lower in those with educational support. CONCLUSION: Setting high thresholds for total DQ and evaluating detailed subscales at age 3 years may be useful for developmental follow-up in extremely preterm infants.

SMAD4 mutations causing Myhre syndrome are under positive selection in the male germline.

While it is widely thought that de novo mutations (DNMs) occur randomly, we previously showed that some DNMs are enriched because they are positively selected in the testes of aging men. These "selfish" mutations cause disorders with a shared presentation of features, including exclusive paternal origin, significant increase of the father's age, and high apparent germline mutation rate. To date, all known selfish mutations cluster within the components of the RTK-RAS-MAPK signaling pathway, a critical modulator of testicular homeostasis. Here, we demonstrate the selfish nature of the SMAD4 DNMs causing Myhre syndrome (MYHRS). By analyzing 16 informative trios, we show that MYHRS-causing DNMs originated on the paternally derived allele in all cases. We document a statistically significant epidemiological paternal age effect of 6.3 years excess for fathers of MYHRS probands. We developed an ultra-sensitive assay to quantify spontaneous MYHRS-causing SMAD4 variants in sperm and show that pathogenic variants at codon 500 are found at elevated level in sperm of most men and exhibit a strong positive correlation with donor's age, indicative of a high apparent germline mutation rate. Finally, we performed in vitro assays to validate the peculiar functional behavior of the clonally selected DNMs and explored the basis of the pathophysiology of the different SMAD4 sperm-enriched variants. Taken together, these data provide compelling evidence that SMAD4, a gene operating outside the canonical RAS-MAPK signaling pathway, is associated with selfish spermatogonial selection and raises the possibility that other genes/pathways are under positive selection in the aging human testis.

Risk of ocular neovascular conversion and systemic bleeding complications in patients with AMD on DOACs or Warfarin.

PURPOSE: Conversion to neovascular disease in patients with non-neovascular age-related macular degeneration (AMD) initiated on direct oral anticoagulants (DOAC) compared to matched patients treated with warfarin. DESIGN: Retrospective cohort study. SUBJECTS, PARTICIPANTS, AND/OR CONTROLS: The study included 20,300 patients and 13,387 patients with non-neovascular AMD initiated on DOACs or warfarin, respectively, before propensity score matching (PSM). METHODS, INTERVENTION, OR TESTING: TriNetX (Cambridge, MA, USA), was used to identify patients diagnosed with non-neovascular AMD stratified by treatment with DOACs or warfarin with at least six months of follow-up. Propensity score matching was performed to control for baseline demographics and medical comorbidities. MAIN OUTCOME MEASURES: Relative risk (RR) of developing neovascular AMD, macular hemorrhage (MH), vitreous hemorrhage (VH), and requiring an ocular intervention (intravitreal anti-vascular endothelial growth factor (VEGF) therapy or pars plana vitrectomy (PPV)) within six months and one year. Patients with chronic atrial fibrillation (AF) on anticoagulation were separately evaluated for the same measures within 5 years after initiating therapy. RESULTS: Treatment with warfarin was associated with higher risk of developing neovascular AMD at six months (RR,1.24, 95% CI, 1.12 - 1.39; P<.001) and one year (RR, 1.26, 95% CI, 1.14 - 1.40; P<.001) when compared to matched patients treated with DOACs. There was an increased risk of requiring intravitreal anti-VEGF therapy (6 months: RR, 1.30; 95% CI, 1.13-1.49; P<.001; 1 year: RR, 1.31, 95% CI, 0.72 - 2.05; P<.001) and PPV (6 months: RR, 1.16; 95% CI, 1.16-3.94; P = .01; 1 year: RR, 2.29, 95% CI, 1.30 - 4.05; P=.003). Among patients with AMD and AF treated with warfarin, there was an increased risk of ocular complications (neovascular AMD: RR, 1.25; 95% CI, 1.14-1.38; P<.001; MH: RR, 1.86; 95% CI, 1.47-2.35; P<.001; VH: RR, 2.22; 95% CI, 1.51-3.26; P<.001) and need for intravitreal anti-VEGF therapy (RR, 1.34; 95% CI, 1.18-1.52; P<.001) over an extended 5-year period. There was no significant difference in the development of major systemic hemorrhagic events between the two cohorts over five years. CONCLUSIONS: Patients with non-neovascular AMD treated with warfarin were more likely to develop neovascular disease and require ocular intervention for hemorrhagic complications when compared to matched patients initiated on DOACs.

Prevalence and clinical predictors of vasodepressor syncope during head up tilt test.

INTRODUCTION: The aim of our study was to evaluate the prevalence and clinical predictors of vasodepressor (VD) response during head-up tilt test (HUTT) in patients with history of syncope admitted to a tertiary referral syncope unit. MATERIAL AND METHODS: We retrospectively evaluated all consecutive patients who underwent HUTT for suspected or established reflex syncope at our institution from March 1st, 2017, to June 1st, 2023. VD response was defined when syncope occurred during hypotension along with no or slight (< 10% bpm) decrease of heart rate. Univariate and multivariate analyses were performed to test the association of VD response to HUTT with a set of clinical covariates. RESULTS: 1780 patients (40 ± 19.9 years; 49.3% male) were included; among them, 1132 (63 %) showed a positive response to HUTT and 124 (7.0%) had a VD response. The prevalence of VD response showed a peak after 69 years (11.52% vs 6.18%; P = 0.0016), mainly driven by male patients (13.7% vs 4.9%; P < 0.0001). At multivariate analysis, age (OR: 1.15; P = 0.0026) was independently associated to HUTT-induced VD syncope; in contrast, smoking (OR: 0.33: P = 0.0009) and non-classical presentation of syncope (OR: 0.55; P = 0.0029) inversely correlated with VD syncope. CONCLUSIONS: VD response represents the less frequent responses among those induced by HUTT, accounting up to 7% of overall responses. A gender and age-related distribution has been shown. Advanced age was the only independent predictor of VD syncope; conversely, smoking and non-classical presentation of syncope reduced the probability of VD response to HUTT.

Vestibular schwannoma microneurosurgery in patients over 70: a single institution experience and proposal of a treatment algorithm.

BACKGROUND: Elderly patients with vestibular schwannoma (VS) are commonly observed. OBJECT: Retrospective analysis of 25 patients aging ≥ 70 operated on in our neurosurgical department for unilateral VS. The purpose of our study is to propose an algorithm for the treatment of VS in elderly patients. METHODS: American Society of Anesthesiology (ASA) Grade I-II patients and Grade III with life-threatening tumors were enrolled. Karnofsky Performance Status Scale (KPS) was used for evalutation of the quality of life. The House-Brackmann (HB) scale for facial nerve (FN) outcome was used. Tumor size was categorized according to Koos' classification. A retrosigmoid approach was used in all cases, except one in which a translabyrinthine approach was performed. Surgical removal graduation: total (GTR), near total (NTR > 95%), subtotal (STR > 90%). The clinical and radiological follow-up period was set first at six months and then at one year after surgery. FN results evaluation was performed at one year, categorized according to House-Brackmann grades I-VI. RESULTS: Mean age: 74,4 years (70-83); 28% ASA I, 56% ASA II, 16% ASA III. Mean tumor size: 2,7 cm (1,5-4,2 cm). GTR/NTR: 68%, STR 32%. Mortality was zero. At last follow-up (one year after surgery) FN results were: HBI 81%, HBII 9.5%, HBIII 9.5%; HB IV 0%. Only 4 patients had preoperative HB IV, of whom one improved from HB IV to HB III. Transient complications occurred only in large VS. Re-growth of residue after STR was observed in 3 cases, treated with SRS in 2 cases and observed in 1. CONCLUSIONS: An algorithm of treatment of vestibular schwannoma in the elderly is proposed. In particular, in patients in general good conditions, age does not appear to be a major contraindication for microsurgery of VS. FN results at last follow-up are satisfactory and the complication rates are acceptable.

Decreasing trend in thyroid cancer incidence: a study from central Italy (2007-2019).

PURPOSE: Due to overdiagnosis, the incidence of thyroid cancer (TC) has increased in high-income countries, including Italy. Efforts have been made to address this issue since the mid-2010s, but more information is needed about how TC incidence has changed. We aim to examine the trend in TC incidence in the Lazio Region (central Italy) and assess the impact of the 2014 Italian Consensus for the Classification and Reporting of Thyroid Cytology (ICCRTC) to identify potential changes in TC diagnosis. METHODS: To identify TC cases, we conducted a population-based study (period 2007-2019) using the data from the Lazio Region Cancer Registry (5.8 million residents). We calculated the annual age-standardized incidence rates of TC for both sexes and analyzed the impact of ICCRTC on monthly incidence rates using segmented linear regression applied to interrupted time-series (ITS). RESULTS: Throughout the 13 years, there was a significant decline in TC annual incidence rates, more pronounced in females. Our results are consistent with reports from outside Europe (United States and South Korea). Following ICCRTC implementation in 2014, a step-change reduction in both sexes was revealed. CONCLUSIONS: Our study indicates a significant decrease in the incidence of TC, particularly among females. The ITS analysis highlights the possible role of ICCRTC in reducing overdiagnosis. As the Lazio Region reflects the Italian population in terms of various demographic, health, and lifestyle indicators, our findings can be applicable at the national level.

Patterns of teachers' responses to school bullying and their associations with training, self-efficacy, and age: A moderated mediation model.

Bullying remains a pervasive issue in educational settings worldwide. This study examined the effect of teacher training and self-efficacy on teachers' responses to school bullying with the moderating effect of age. Drawing on data from 585 Taiwanese primary and secondary school teachers, the study revealed six distinct response patterns to bullying among Taiwanese teachers. The results underscore the critical role of self-efficacy in enabling proactive responses to bullying, highlighting that training programs that boost teachers' self-efficacy can be effective across different age groups. Furthermore, the research points to the necessity of differentiated training approaches that consider teachers' age to enhance responses of mediating involvers. This study contributes to the broader discourse on bullying prevention, emphasizing the importance of teacher training and the need for further research into the nuanced relationships between teacher characteristics, self-efficacy, and intervention strategies in diverse cultural settings.

External validation of models to estimate gestational age in the second and third trimester using ultrasound: A prospective multicentre observational study.

OBJECTIVES: Accurate assessment of gestational age (GA) is important at both individual and population levels. The most accurate way to estimate GA in women who book late in pregnancy is unknown. The aim of this study was to externally validate the accuracy of equations for GA estimation in late pregnancy and to identify the best equation for estimating GA in women who do not receive an ultrasound scan until the second or third trimester. DESIGN: This was a prospective, observational cross-sectional study. SETTING: 57 prenatal care centres, France. PARTICIPANTS: Women with a singleton pregnancy and a previous 11-14-week dating scan that gave the observed GA were recruited over an 8-week period. They underwent a standardised ultrasound examination at one time point during the pregnancy (15-43 weeks), measuring 12 foetal biometric parameters that have previously been identified as useful for GA estimation. MAIN OUTCOME MEASURES: A total of 189 equations that estimate GA based on foetal biometry were examined and compared with GA estimation based on foetal CRL. Comparisons between the observed GA and the estimated GA were made using R2, calibration slope and intercept. RMSE, mean difference and 95% range of error were also calculated. RESULTS: A total of 2741 pregnant women were examined. After exclusions, 2339 participants were included. In the 20 best performing equations, the intercept ranged from -0.22 to 0.30, the calibration slope from 0.96 to 1.03 and the RSME from 0.67 to 0.87. Overall, multiparameter models outperformed single-parameter models. Both the 95% range of error and mean difference increased with gestation. Commonly used models based on measurement of the head circumference alone were not amongst the best performing models and were associated with higher 95% error and mean difference. CONCLUSIONS: We provide strong evidence that GA-specific equations based on multiparameter models should be used to estimate GA in late pregnancy. However, as all methods of GA assessment in late pregnancy are associated with large prediction intervals, efforts to improve access to early antenatal ultrasound must remain a priority. TRIAL REGISTRATION: The proposal for this study and the corresponding methodological review was registered on PROSPERO international register of systematic reviews (registration number: CRD4201913776).

Short-term effects of announcing spirometric lung-age on smokers' attitudes: results from a Tunisian real-life pilot study.

BACKGROUND: To determine the effect of informing smokers of their spirometric lung-age (SLA) on smoking cessation (SC) rates and tobacco consumption. RESEARCH DESIGN AND METHODS: An interventional study was conducted in real-life through a humanitarian event led by the Red Crescent on 9 January 2022, in Hammam-Sousse (Sousse, Tunisia). The study comprised four steps: i) Medical questionnaire (general questionnaire, Fagerström test for cigarette dependence, SC motivation questionnaire); ii) Measurement of spirometric data; iii) SLA estimation and its announcement to participants; and iv) Self-reported evaluation of smoking behavior three months later through telephonic recall. Smokers were divided into groups (nondependent vs. dependent groups and insufficient/moderate motivation vs. high/very high motivation groups) and categories (ceased smoking, reduced consumption, maintained stable or increased consumption). RESULTS: Fifty-two smokers were included (94% were males). Three months after the event, i) 9 (17%) smokers ceased smoking, ii) 39 (75%) smokers reduced their daily smoking consumption by 12 ± 8 cigarettes/day, and iii) 4 (8%) smokers maintained stable (n = 3) or increased (n = 1) consumption. CONCLUSIONS: Informing smokers of their SLA led 92% of them to cease smoking or reduce their consumption. Announcing SLA could be an effective motivational tool and an easy-to-understand concept to help smokers cease their habit.

OGG1: An emerging multifunctional therapeutic target for the treatment of diseases caused by oxidative DNA damage.

Oxidative DNA damage-related diseases, such as incurable inflammation, malignant tumors, and age-related disorders, present significant challenges in modern medicine due to their complex molecular mechanisms and limitations in identifying effective treatment targets. Recently, 8-oxoguanine DNA glycosylase 1 (OGG1) has emerged as a promising multifunctional therapeutic target for the treatment of these challenging diseases. In this review, we systematically summarize the multiple functions and mechanisms of OGG1, including pro-inflammatory, tumorigenic, and aging regulatory mechanisms. We also highlight the potential of OGG1 inhibitors and activators as potent therapeutic agents for the aforementioned life-limiting diseases. We conclude that OGG1 serves as a multifunctional hub; the inhibition of OGG1 may provide a novel approach for preventing and treating inflammation and cancer, and the activation of OGG1 could be a strategy for preventing age-related disorders. Furthermore, we provide an extensive overview of successful applications of OGG1 regulation in treating inflammatory, cancerous, and aging-related diseases. Finally, we discuss the current challenges and future directions of OGG1 as an emerging multifunctional therapeutic marker for the aforementioned challenging diseases. The aim of this review is to provide a robust reference for scientific researchers and clinical drug developers in the development of novel clinical targeted drugs for life-limiting diseases, especially for incurable inflammation, malignant tumors, and age-related disorders.

Insomnia and the effect of zolpidem-extended-release on the sleep items of the Hamilton Rating Scale for Depression in outpatients with depression, insomnia, and suicidal ideation: Relationship to patient age.

BACKGROUND: There are limited data regarding gamma-aminobutyric acid (GABA) allosteric modulator sleep-aid medications in persons with depression, insomnia, and suicidal ideation (SI). AIMS: This secondary analysis examined the relationship of age to insomnia and the impact of age on the treatment of insomnia with zolpidem extended-release (zolpidem-ER) in depressed suicidal patients. A prior report found that the addition of zolpidem-ER promoted significantly superior reductions in global severity of insomnia in depressed outpatients with insomnia and SI over 8 weeks, but here we report the differences among early, middle, and late insomnia. METHODS: This secondary analysis examined the three early, middle, and late insomnia items of the Hamilton Rating Scale for Depression (HRSD) and their relationship to age and responsiveness to treatment with zolpidem-ER. One hundred and three patients with major depression, SI, and insomnia received open-label serotonin reuptake inhibitors and were randomly allocated 1:1 to receive zolpidem-ER or placebo at bedtime. Results: Older age at baseline was associated with worse middle and late insomnia, but not with early insomnia. Subsequent treatment with zolpidem-ER produced superior improvement in early and middle insomnia, but not late insomnia. CONCLUSIONS: These findings are consistent with the known age-related advancement of sleep timing in the general population and depressed outpatients and with the expected effects of a short half-life GABA allosteric modulator sleep aid. By implication, prescribers of pharmacologic treatment of insomnia in depressed patients should consider an alternative to zolpidem-ER when late insomnia is a concern.Trial registration number: ClinicalTrials.gov Identifier: NCT01689909.

Advanced maternal age (AMA) and pregnancy: a feasible but problematic event.

This narrative review aimed to summarize all adverse outcomes of pregnancy in advanced maternal age (AMA) to assess the age of the mother as a potentially crucial risk factor. AMA refers to women older than 35 years. While expectations and the role of women in society have undergone significant changes today, the biology of aging remains unchanged. Various pathologic changes occur in the human body with age, including chronic noncommunicable diseases, as well as notable changes in reproductive organs, that significantly affect fertility. Despite substantial advancements in technology and medicine, pregnancy in AMA remains a formidable challenge. Although there are some advantages to postponing childbirth, they primarily relate to maternal maturity and economic stability. However, regrettably, there are also many adverse aspects of pregnancy at advanced ages. These include complications affecting both the mother and the fetus. Pregnants in AMA were more prone to suffer from gestational diabetes mellitus, preeclampsia, and eclampsia during pregnancy compared to younger women. In addition, miscarriages and ectopic pregnancies were more prevalent. Delivery was more frequently completed via cesarean section, and postpartum complications and maternal mortality were also higher. Unfortunately, there were also complications concerning the fetus, such as chromosomal abnormalities, premature birth, low birth weight, admission to the neonatal intensive care unit, and stillbirth.

The impact of medical insurance and old-age security on the utilization of medical services by the older population with disabilities.

OBJECTIVE: In this study, the impact of medical insurance and old-age security on the use of medical services by the older population with disabilities is analyzed. A reference for decision makers is provided to improve medical and old-age security policies and enhance the use of medical services by the older population. METHODS: Data were drawn from 3,737 older people with disabilities aged 65 years or above from the 2018 China Longitudinal Healthy Longevity Survey. A two-part model based on social ecological theory was used for both analysis and group prediction. RESULTS: In terms of the use of outpatient medical services, old-age pension significantly increased the probability of outpatient visits for this population group (P < 0.05). Urban employee/resident medical insurance, the new rural cooperative medical insurance, and retirement pension significantly affected medical expenses. In terms of the use of inpatient medical services, the new rural cooperative medical insurance and retirement pension significantly influenced the choice of inpatient medical services; retirement pension increased inpatient medical expenditure (p < 0.01). The expected average probability of hospitalization, unconditional expected cost, and conditional expected cost for the older population with disabilities were 49.5%, RMB 6629.31, and RMB 3281.51, respectively. Both conditional and unconditional expected costs were significantly higher for older people with disabilities with the following attributes: male, married, no less than three chronic conditions, and unassisted daily care; costs were lower for older people with disabilities who are female, not married, had less than three chronic conditions, and had a spouse, child, or other caregiver. CONCLUSION: Medical insurance and old-age security can significantly promote the utilization of medical services by the older population with disabilities. It is therefore recommended to focus on strengthening the support and health management of these people who are unattended to improve the effective use of health services and better meet their needs.

Donor and newborn profiles and their influence on donation volume and duration: a cross-sectional study in a Spanish human milk bank.

BACKGROUND: Human milk banks are essential facilities to provide donated human milk (DHM) to preterm and term infants with health complications. Little is known regarding milk bank donors and how their characteristics may influence the particularities of the donation process. The present study aims to assess characteristics of donors and their newborns to identify associations with the amount of DHM and initiation and donation time, during the first and second year of the milk bank operation in Córdoba, Spain. METHODS: This cross-sectional study was conducted in three periods: pre-opening of the milk bank (PRE) including all women who gave birth to a newborn between January - May 2017 and were hospital users; donors in the first year after the opening (Period 1 (P1): April 2019 - March 2020); and in the second year (P2: April 2020 - March 2021). For P1 and P2, DHM data were recorded. The relationships between donor and newborn characteristics and the donation process were examined using univariable and regression models. RESULTS: From 391 women interviewed in the PRE period, 55 (14%) showed intention to donate. In P1 and P2, there were 51 and 25 human milk (HM) donors, respectively. Age, gestational age (GA) and parity were similar between periods. In P2, a higher proportion of donors had higher education (P1: 46%; P2: 70.8%, p = 0.045). Around 40% of donors in both periods were on maternity leave. In P1, donors who had low birth weight infants (< 2500 g) donated more HM than those with infants weighing ≥ 2500 g (p = 0.020). In P2, women whose GA was < 37 weeks donated a higher volume vs. those with ≥ 37 weeks (p = 0.002). Maternity leave was linked to a shorter initiation time for donations in both periods (P1: p = 0.002; P2: p < 0.001). CONCLUSIONS: Data obtained from a Spanish human milk bank indicate that prematurity and low birth weight appear to influence the amounts of DHM. Employment status might be a decisive factor in initiating HM donation. Additional efforts are required to identify shared donor characteristics that influence the initiation and volume of donation.

Exploring the Link Between Intraocular Pressure and Central Corneal Thickness, as Well as the Diurnal Variation of Intraocular Pressure, in the Elderly Population of North Karnataka.

Purpose The study aimed to understand the relationship between intraocular pressure (IOP) and central corneal thickness (CCT) in older adults living in North Karnataka and the diurnal variation of IOP in the elderly population. Methods This is a population-based cross-sectional study in which 84 eyes of 42 study participants aged over 50 years were examined. A complete ophthalmic examination was done for all subjects. IOP was measured with an iCare IC100 (Icare Finland Oy, Vantaa, Finland) rebound tonometer and CCT with an ultrasound pachymeter. Statistical significance was accepted as p<0.05. Results The mean age of the study participants was 64.42±6.917 years. The mean IOP and CCT at 1 pm were 12.4±2.576 and 509.24±25.379 in the right eye, and 12.45±2.319 and 511.05±24.464 in the left eye. Spearman's correlation showed that IOP was positively correlated with CCT, with p<0.05. This showed that CCT has the most significant impact on IOP. In our study, the diurnal variation of IOP by paired samples t-test was also crucial in the elderly population, with p<0.05. Conclusion In this study, IOP was reduced as the CCT was reduced, and vice versa, i.e., IOP was positively correlated with CCT. The diurnal variation of IOP in older people was the same as in the young and middle-aged population, i.e., the highest recording of IOP was in the morning, and it gradually reduced as the day passed.

Trends in three malnutrition factors in the global burden of disease: iodine deficiency, vitamin A deficiency, and protein-energy malnutrition (1990-2019).

Background: Vitamin A deficiency, iodine deficiency, and protein-energy malnutrition are prevalent malnutrition issues that disproportionately affect low-income countries and pose significant risks to the health and development of children and adolescents. This study offers a detailed examination of these deficiencies' prevalence trends and gender and regional variations using Global Burden of Disease Study data from 1990 to 2019. It also assesses the specific impact on various age groups, providing essential insights for targeted health interventions and policy-making. Methods: Data spanning from 1990 to 2019 on Vitamin A deficiency, iodine deficiency, and protein-energy malnutrition were extracted from the 2019 Global Burden of Disease Study. Age-Standardized Incidence Rates (ASR) were computed by gender, region, and etiology, utilizing the estimated annual percentage change (EAPC) to assess temporal trends. Results: In 2019, Central Sub-Saharan Africa had the highest prevalence of Vitamin A deficiency, particularly among males, and iodine deficiency peaked in the same region for both genders. South Asia had the highest incidence of protein-energy malnutrition for both genders. Regions with a low Socio-Demographic Index (SDI) showed lower ASR for these deficiencies. Notably, Cameroon, Equatorial Guinea, and Maldives recorded the highest ASR for vitamin A deficiency, iodine deficiency, and protein-energy malnutrition, respectively. The declining ASR trend for vitamin A deficiency, especially among males, suggests effective interventions. East Asia saw a significant increase in iodine deficiency ASR from 1990 to 2019, particularly among women, requiring targeted interventions. The rising ASR of protein-energy malnutrition in several regions, especially among men, raises concerns. Vitamin A deficiency primarily affected children and adolescents, iodine deficiency predominantly impacted adolescents and young adults, and protein-energy malnutrition was chiefly observed among children under 5 years old. These findings underscore the necessity for tailored interventions considering age-specific nutritional needs and challenges.
