Integrated analysis of yield response and early stage biochemical, molecular, and gene expression profiles of pre-breeding rice lines under water deficit stress.

Breeding high yielding water-deficit tolerant rice is considered a primary goal for achieving the objectives of the sustainable development goals, 2030. However, evaluating the performance of the pre-breeding-promising parental-lines for water deficit tolerance prior to their incorporation in the breeding program is crucial for the success of the breeding programs. The aim of the current investigation is to assess the performance of a set of pre-breeding lines compared with their parents. To achieve this goal a set of 7 pre-breeding rice lines along with their parents (5 genotypes) were field evaluated under well-irrigated and water-stress conditions. Water stress was applied by flush irrigation every 12 days without keeping standing water after irrigation. Based on the field evaluation results, a pre-breeding line was selected to conduct physiological and expression analysis of drought related genes at the green house. Furthermore, a greenhouse trial was conducted in pots, where the genotypes were grown under well and stress irrigation conditions at seedling stage for physiological analysis and expression profiling of the genotypes. Results indicated that the pre-breeding lines which were high yielding under water shortage stress showed low drought susceptibility index. Those lines exhibited high proline, SOD, TSS content along with low levels of MDA content in their leaves. Moreover, the genotypes grain yield positively correlated with proline, SOD, TSS content in their leaves. The SSR markers RM22, RM525, RM324 and RM3805 were able to discriminate the tolerant parents from the sensitive one. Expression levels of the tested drought responsive genes revealed the upregulation of OsLEA3, OsAPX2, OsNAC1, OSDREB2A, OsDREB1C, OsZIP23, OsP5CS, OsAHL1 and OsCATA genes in response to water deficit stress as compared to their expression under normal irrigated condition. Taken together among the tested pre-breeding lines the RBL112 pre-breeding line is high yielding under water-deficit and could be used as donor for high yielding genes in the breeding for water deficit resistance. This investigation withdraws attention to evaluate the promising pre-breeding lines before their incorporation in the water deficit stress breeding program.

The odds of having obesity in Egyptian children with autism spectrum disorders is higher than stunting compared to healthy developing peers: a national survey.

BACKGROUND: The nutritional status and growth of children with Autism spectrum disorders (ASD) is influenced significantly by two factors; food selectivity behaviors due to their consumption of a limited variety of food and the high incidence of gastrointestinal (GIT) disorders. AIM: This study aimed to assess the nutritional adequacy and growth pattern of ASD children aged three to twelve years compared to their healthy developing peers. METHODS: A national comparative, facility-based cross-sectional study was conducted in eight Egyptian governorates on 285 Egyptian children diagnosed with ASD and 224 children who are their relatives as healthy developing peers. Anthropometric measurements were obtained, including weight, height, head circumference, and mid-upper arm circumference. Body Mass Index (BMI) was calculated and all numbers were plotted on WHO growth charts. Assessment of food preferences, and nutrient intake adequacy of children was done using the Food preference questionnaire, and the Dietary Reference Intakes (DRIs) of Egyptian children. RESULTS: Calorie-dense food and sugar intake were higher among ASD children than their healthy developing peers. ASD children omit some important protein sources such as dairy (COR = 5.2, 95% CI:2.7-9.9), meat, and poultry (COR = 2.7, 95% CI: 1.6-4.7), and a lower intake of fruits and vegetables than their healthy developing peers. For children with ASD in all age groups, a deficiency in the range of 50-60% was detected for vitamins (C, D, B6, thiamine, riboflavin, niacin) and minerals (iron). A deficiency in the range of 60-70% was detected for folate and calcium. A deficiency of vitamin C calcium and iron was also detected for both children with ASD and their healthy developing relatives aged 6 to 12 years. GIT disorders were common among ASD children compared to healthy developing peers (COR = 2.8 to 10.3). Children with ASD had four-fold higher odds of stunting (COR = 4.1, CI: 1.7-10.1), threefold higher odds of being overweight (COR = 3.3, CI: 1.48-7.32), and nearly eleven-fold higher odds of obesity (COR = 11.4, CI: 4.05-32.17) compared to their healthy developing peers. CONCLUSION: ASD children are prone to overweight and protein malnutrition. Their intake of fruits and vegetables is inadequate and hence their intake of vitamins and minerals is insufficient, contributing to stunting.

The pharmacists' interventions after a Drug and Therapeutics Committee (DTC) establishment during the COVID-19 pandemic.

Introduction: Healthcare systems in developing countries faced significant challenges during COVID-19, grappling with limited resources and staffing shortages. Assessment of the impact of pharmaceutical care expertise, particularly in critical care units during the pandemics, in developing countries remains poorly explored. The principal aim of our study was to assess the impact of the Drug and Therapeutics Committee (DTC), comprising clinical pharmacists, on the incidence, types, and severity of medication errors and associated costs in using COVID-19 medications, especially antibiotics. Methods: An interventional pre-post study was carried out at a public isolation hospital in Egypt over 6 months. Results: Out of 499 medication orders, 238 (47.7%) had medication errors, averaging 2.38 errors per patient. The most frequent were prescribing errors (44.9%), specifically incorrect drug choice (57.9%), excessive dosage (29.9%), treatment duplication (4.5%), inadequate dosage (4.5%), and overlooked indications (3.6%). Linezolid and Remdesivir were the most common medications associated with prescribing errors. Pharmacists intervened 315 times, primarily discontinuing medications, reducing doses, introducing new medications, and increasing doses. These actions led to statistically significant cost reductions (p < 0.05) and better clinical outcomes; improved oxygen saturation, decreased fever, stabilised respiratory rates, and normalised white blood cell counts. So, clinical pharmacist interventions made a notable clinical and economic difference (66.34% reduction of the expenses) in antibiotics usage specifically and other medications used in COVID-19 management during the pandemic. Conclusion: Crucially, educational initiatives targeting clinical pharmacists can foster judicious prescribing habits.

Inhibitory Effect of Two Carbonic Anhydrases Inhibitors on the Activity of Major Cytochrome P450 Enzymes.

BACKGROUND AND OBJECTIVES: Both AW-9A (coumarin derivative) and WES-1 (sulfonamide derivative) were designed and synthesized as potential selective carbonic anhydrase inhibitors and were tested for anticancer activity. This study was undertaken to investigate their potential inhibitory effects on the major human cytochrome P450 (CYP) drug-metabolizing enzymes. METHODS: Specific CYP probe substrates and validated analytical methods were used to measure the activity of the tested CYP enzymes. Furthermore, in silico simulations were conducted to understand how AW-9A and WES-1 bind to CYP2A6 at a molecular level. Molecular docking experiments were performed using the high-resolution X-ray structure, Protein Data Bank (PDB) ID: 2FDV for CYP2A6. RESULTS: CYP2E1-catalyzed chlorzoxazone-6'-hydroxylation was strongly inhibited by AW-9A and WES-1 with IC50 values of 0.084 µM and 0.101 µM, respectively. CYP2A6-catalyzed coumarin-7'-hydroxylation was moderately inhibited by AW-9A (IC50 = 4.2 µM). CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A4 enzymes were weakly or negligibly inhibited by both agents. Docking studies suggest elevated potential to block the catalytic activity of CYP2A6. CONCLUSIONS: These findings point to the feasibility of utilizing these agents as promising chemopreventive agents (owing to inhibition of CYP2E1), and AW-9A as a smoking cessation aid (owing to inhibition of CYP2A6). Additional in-vivo studies should be conducted to examine the impact of CYP2A6 and CYP2E1 inhibition on drug interactions with probe substrates of these enzymes.

The genetic orchestra of salicylic acid in plant resilience to climate change induced abiotic stress: critical review.

Climate change, driven by human activities and natural processes, has led to critical alterations in varying patterns during cropping seasons and is a vital threat to global food security. The climate change impose several abiotic stresses on crop production systems. These abiotic stresses include extreme temperatures, drought, and salinity, which expose agricultural fields to more vulnerable conditions and lead to substantial crop yield and quality losses. Plant hormones, especially salicylic acid (SA), has crucial roles for plant resiliency under unfavorable environments. This review explores the genetics and molecular mechanisms underlying SA's role in mitigating abiotic stress-induced damage in plants. It also explores the SA biosynthesis pathways, and highlights the regulation of their products under several abiotic stresses. Various roles and possible modes of action of SA in mitigating abiotic stresses are discussed, along with unraveling the genetic mechanisms and genes involved in responses under stress conditions. Additionally, this review investigates molecular pathways and mechanisms through which SA exerts its protective effects, such as redox signaling, cross-talks with other plant hormones, and mitogen-activated protein kinase pathways. Moreover, the review discusses potentials of using genetic engineering approaches, such as CRISPR technology, for deciphering the roles of SA in enhancing plant resilience to climate change related abiotic stresses. This comprehensive analysis bridges the gap between genetics of SA role in response to climate change related stressors. Overall goal is to highlight SA's significance in safeguarding plants and by offering insights of SA hormone for sustainable agriculture under challenging environmental conditions.

Succinyl Curcumin Conjugated Chitosan Polymer-Prodrug Nanomicelles: A Potential Treatment for Type-II Diabetes in Diabetic Balb/C Mice.

Diabetes mellitus is a chronic metabolic disorder marked by elevated blood sugar levels, leading to organ dysfunction. Curcumin, derived from turmeric, exhibits promise in managing type II diabetes. Nanomicelles were created by conjugating curcumin with chitosan through succinic anhydride. Succinyl-curcumin, the resultant compound, was esterified with chitosan to form a polymer prodrug conjugate. Nanomicelles, formed via dialysis, were spherical with a hydrodynamic size of 49.37 nm. In vitro release studies revealed 97% curcumin release at pH 5 in 7 days. A 21-day experiment on diabetic mice compared nanomicelles, standard drug, and free curcumin's impact on fasting blood glucose. The study showcased gradual, controlled curcumin release from nanomicelles, suggesting their potential in type II diabetes treatment.

How did the use of the social marketing approach in Egyptian communities succeed in improving breastfeeding practices and infants' growth?

INTRODUCTION: Improving breastfeeding practices does not always link to interventions relying only on improving nutrition awareness and education but needs cultural and behavioral insights . AIM: This study aimed to evaluate the changes in core breastfeeding indicators as a result of the use of social marketing (SM) approach for improving breastfeeding practices of Egyptian women and the physical growth of infants aged 6 to 12 months. The core breastfeeding indicators were: Early initiation of breastfeeding within one hour of birth, Predominant and exclusive breastfeeding to 6 months (EBF), Bottle feeding with formula, continued breastfeeding to 1 and 2 years, and responsiveness to cues of hunger and satiety. METHODS: A quasi-experimental longitudinal study with a posttest-only control design was done over 3 years in three phases; the first was in-depth interviews and formative research followed by health education and counseling interventions and ended by measuring the outcome. Motivating mothers' voluntary behaviors toward breastfeeding promotion "feeding your baby like a baby" was done using SM principles: product, price, place, and promotion. The interventions targeted 646 pregnant women in their last trimester and delivered mothers and 1454 women in their childbearing period. The statistical analysis was done by using SPSS program, version 26. RESULTS: Most mothers showed significantly increased awareness about the benefits of breastfeeding and became interested in breastfeeding their children outside the house using the breastfeeding cover (Gawn) (p < 0.05). Breastfeeding initiation, exclusive breastfeeding under 6 months, frequency of breastfeeding per day, and percentage of children who continued breastfeeding till 2 years, were significantly increased (from 30%, 23%, 56%, and 32% to 62%, 47.3%, 69%, and 43.5% respectively). The girls who recorded underweight results over boys during the first year of life were significantly improved (p < 0.01) after the intervention (from 52.1% to 18.8% respectively). At the same time, girls found to be obese before the intervention (15.6%) became no longer obese. CONCLUSIONS: Improvement for the majority of the key breastfeeding indicators and physical growth of infants indicates that raising a healthy generation should start by promoting breastfeeding practices that are respectable to societal norms.

Pesticides impacts on human health and the environment with their mechanisms of action and possible countermeasures.

Pesticides are chemical constituents used to prevent or control pests, including insects, rodents, fungi, weeds, and other unwanted organisms. Despite their advantages in crop production and disease management, the use of pesticides poses significant hazards to the environment and public health. Pesticide elements have now perpetually entered our atmosphere and subsequently contaminated water, food, and soil, leading to health threats ranging from acute to chronic toxicities. Pesticides can cause acute toxicity if a high dose is inhaled, ingested, or comes into contact with the skin or eyes, while prolonged or recurrent exposure to pesticides leads to chronic toxicity. Pesticides produce different types of toxicity, for instance, neurotoxicity, mutagenicity, carcinogenicity, teratogenicity, and endocrine disruption. The toxicity of a pesticide formulation may depend on the specific active ingredient and the presence of synergistic or inert compounds that can enhance or modify its toxicity. Safety concerns are the need of the hour to control contemporary pesticide-induced health hazards. The effectiveness and implementation of the current legislature in providing ample protection for human health and the environment are key concerns. This review explored a comprehensive summary of pesticides regarding their updated impacts on human health and advanced safety concerns with legislation. Implementing regulations, proper training, and education can help mitigate the negative impacts of pesticide use and promote safer and more sustainable agricultural practices.

Safety and immunogenicity of Vi-diphtheria toxoid typhoid conjugate vaccine among children below 2 years: a systematic review and meta-analysis.

Background: The Vi-diphtheria toxoid typhoid conjugate vaccine (Vi-DT) has shown promising results in preventing typhoid fever in children under 2 years of age. However, a thorough assessment of its safety and immunogenicity is required to inform vaccination strategies. This systematic review and meta-analysis aimed to determine the safety and immunogenicity of Vi-DT in children below 2 years. Methods: We systematically searched multiple databases, including PubMed, Web of Science, and Scopus, for relevant studies published up to September 2023. We included studies reporting on the safety and immunogenicity outcomes of Vi-DT compared to the control or Vi-tetanus toxoid conjugated vaccine (Vi-TT) in children below 2 years. We applied a random-effects model for meta-analysis using RevMan 5.4. We expressed the results as risk ratio (RR) with a 95% confidence interval (95%CI). Results: In this analysis, five studies were selected, encompassing 1,292 children under 2 years who received the Vi-DT vaccine. No significant difference in immediate reactions was observed within 30 min post-vaccination between Vi-DT and control groups (RR: 0.99 [95% CI: 0.19, 5.26]), nor between Vi-DT and Vi-TT groups. For solicited adverse events within 4 weeks, the VI-DT group showed no significant increase in adverse events compared to control (RR: 0.93 [95% CI: 0.78, 1.12]) or Vi-TT (RR: 0.86 [95% CI: 0.69, 1.07]). Similarly, within 7 days post-vaccination, risk ratios indicated no significant differences in adverse events between the groups. The 4-week seroconversion rate was significantly higher in the Vi-DT group compared to the control (RR: 1.99 [95% CI: 1.07, 3.69]), but no difference was found between Vi-DT and Vi-TT. Adverse events associated with typhoid conjugate vaccines were predominantly non-serious, including fever and injection site reactions. Serious adverse events were rare but included conditions like pneumonia and gastroenteritis. Conclusion: This meta-analysis highlights Vi-DT safety and immunogenicity in six to 24-month-old children. The findings support the use of this Vi-DT to expand typhoid vaccination in endemic regions, in line with WHO's strategy.

Semilunar valve growth and function 10 years after infant heart transplantation: Predicting long-term outcomes of partial heart transplants.

INTRODUCTION: Partial heart transplants are a new type of pediatric transplant that replace defective heart valves with the parts of matched donor hearts containing the necessary valves. Short-term outcomes of partial heart transplants are excellent, but long-term outcomes are unknown. In order to predict the long-term outcomes of partial heart transplants, we evaluated long-term growth and function of semilunar heart valves transplanted in infancy as part of a heart transplant. METHODS: All children who underwent infant heart transplantation at a single center from 1997 to 2014 were included in this study. Children in whom echocardiograms after heart transplantation and after 10 years were not available for review were excluded. The echocardiograms were reviewed by two authors to analyze semilunar valve annulus diameters, Z-scores, peak valve gradients, and valve regurgitation. Statistical difference was determined using two-tailed, paired sample t-tests with Bonferroni correction for multiple comparisons. RESULTS: Data from 15 patients were analyzed. The aortic valve annulus averaged 1.3 cm (range 0.7-1.8 cm) immediately after transplantation and grew to an average of 1.7 cm (range 1.4-2.3 cm) after 10 years (p < .001). After 10 years, the aortic valve peak gradient avereraged 5.1 mmHg (range 2.1-15.5 mmHg) and none of the valves had more than trivial regurgitation. The pulmonary valve annulus averaged 1.5 cm (range 1.1-2.5 cm) immediately after transplantation and grew to an average of 2.1 cm (range 1.0-2.9 cm) after 10 years (p < .001). After 10 years, the pulmonary valve peak gradient averaged 4.3 mmHg (range 1.1-13.8 mmHg), and 7% of valves had moderate regurgitation. DISCUSSION: Semilunar heart valves transplanted in infancy as part of a heart transplant demonstrate statistically significant growth and excellent function after 10 years. This predicts excellent long-term outcomes of partial heart transplants.

Salivary C-reactive protein and mean platelet volume as possible diagnostic markers for late-onset neonatal pneumonia.

BACKGROUND: Neonatal sepsis, a formidable threat to newborns, is a leading cause of neonatal mortality, with late-onset sepsis manifesting after 72 hours post-birth being particularly concerning. Pneumonia, a prevalent sepsis presentation, poses a significant risk, especially during the neonatal phase when lung defenses are compromised. Accurate diagnosis of pneumonia is imperative for timely and effective interventions. Saliva, a minimally invasive diagnostic medium, holds great promise for evaluating infections, especially in infants. AIM: To investigate the potential of serum C-reactive protein (CRP), salivary CRP (sCRP), and mean platelet volume (MPV) as diagnostic markers for late-onset neonatal pneumonia (LONP). METHODS: Eighty full-term neonates were systematically examined, considering anthropometric measurements, clinical manifestations, radiology findings, and essential biomarkers, including serum CRP, sCRP, and MPV. RESULTS: The study reveals noteworthy distinctions in serum CRP levels, MPV, and the serum CRP/MPV ratio between neonates with LONP and healthy controls. MPV exhibited a robust discriminatory ability [area under the curve (AUC) = 0.87] with high sensitivity and specificity at a cutoff value of > 8.8. Correlations between serum CRP, sCRP, and MPV were also identified. Notably, sCRP demonstrated excellent predictive value for serum CRP levels (AUC = 0.89), underscoring its potential as a diagnostic tool. CONCLUSION: This study underscores the diagnostic promise of salivary and serum biomarkers, specifically MPV and CRP, in identifying and predicting LONP among neonates. These findings advocate for further research to validate their clinical utility in larger neonatal cohorts.

The public's perspective on the amount of time surgeons spend operating.

BACKGROUND: As waiting lists for elective surgery grow, there seems to be a disconnect between the public's expectations on the amount of time surgeons spend operating compared with reality. On average, a surgeon in the NHS spends one day a week performing elective surgery. We aimed to investigate the public's perception on the amount of time surgeons spend performing elective surgery and what they would desire. METHODS: Members of the public in the UK were approached randomly either on-line or in-person to complete an anonymised 6-question survey. The questionnaire included demographic details, surgical history, occupational experience in the healthcare sector, the number of days a week they believe and wish for surgeons to be performing elective surgery. RESULTS: 252 members of the public responded to the survey (150 females, 102 males). 38.5% have experience working in the healthcare sector and 58.5% have had surgery in the past. 83.7% believe surgeons spend at least 3 days a week performing elective surgery [3-4 days (43.2%), 5-7 days (40.5%)]. 45.7% of respondents want their surgeon to operate between 5 and 7 days per week. CONCLUSION: The public appears to overestimate the amount of time that surgeons spend performing elective surgery and have unrealistic expectations of how much they want their surgeons to operate.

Comparative clinical evaluation between self-adhesive and conventional bulk-fill composites in class II cavities: A 1-year randomized controlled clinical study.

OBJECTIVE: This randomized controlled clinical trial compared the clinical efficacy of self-adhesive bulk-fill Surefil One with a traditional bulk-fill composite in class II restorations. MATERIALS AND METHODS: Sixty-four direct class II composite restorations were categorized into two groups. Group I, control group (n = 32): cavities were restored by Filtek One bulk-fill composite with Scotchbond Universal (SBU) adhesive in self-etch mode, Group II, test group (n = 32): cavities were restored by Surefil One self-adhesive bulk-fill composite. The study involved a follow-up period of 1 year, during which restorations were assessed at baseline (BL), 6 months, and 12 months using Federation Dentaire Internationale (FDI) criteria. Data analysis was performed using nonparametric tests. A comparison of restoration characteristics was performed utilizing the chi-square test (X2). The significance level was set at 0.05. RESULTS: Filtek One and Surefil One bulk-fill composites revealed clinically acceptable FDI scores over 12-month recalls. Thirty-two patients (64 restorations) were available for all follow-up visits; 100% of the restorations survived. For esthetic properties, Filtek One was far better than Surefil One at all time points. However, in terms of functional and biological properties, both restorations demonstrated comparable performances. CONCLUSIONS: Filtek One bulk-fill restorations were superior in terms of surface luster, surface staining, color match, and translucency, but Surefil One restorations performed well and were similar to Filtek One restorations; however, additional advancements and research are needed to obtain better esthetics. Furthermore, longitudinal studies with extended follow-up periods are needed to assess the clinical potential of both materials. CLINICAL SIGNIFICANCE: Both Filtek One and Surefil One met the FDI criteria, with Filtek One demonstrating superior esthetic and functional qualities and similar performance regarding biological criteria. Both innovative restorative materials show potential for clinical use. Trial registered on ClinicalTrials.gov under registration number; NCT06120868:07/11/2023.

RNA Sequencing Reveals the Inhibitory Effect of High Levels of Arachidonic Acid and Linoleic Acid on C2C12 Differentiation and Myogenic Biomarkers.

Over the past three decades, studies have shown that consuming polyunsaturated fatty acids (PUFAs) can enhance animal and human health and welfare through biological, biochemical, pathological, and pharmacological impacts. Furthermore, omega-6 plays key roles in the cardiopulmonary system, including promoting airway relaxation and inhibiting atherosclerosis and hypertension. However, findings from investigations of the effects of omega-6 fatty acids on molecular and cellular activity and discussions on their influence on biomarkers are still unclear. Therefore, the present study aimed to evaluate omega-6 fatty acids, the arachidonic acid (AA), and linoleic acid (LA) effects on C2C12 proliferation, myogenesis morphology, and relative myogenic biomarker expression through the Wnt pathway. C2C12 cells were cultured with and without 25, 50, 100, and 150 µM of LA and AA and then subjected to CCK8, Giemsa staining, RT qPCR, Western blotting, and RNA Sequencing. The CCK8 Assay results showed that 25, 50, 100, and 150 µM LA significantly decreased the viability after 72 h for 25, 50, 100, and 150 µM concentrations. Also, AA supplementation decreased cell viability after 24 h for 150 µM, 48 h for 150 µM, and 72 h for 50, 100, and 150 µM concentrations. Moreover, the LA and AA inhibitory effects noticed through Gimesa staining were morphological changes during myoblast differentiation. Both LA and AA showed inhibiting IGF1, Cola1, Col6a2, Col6a1, Itga10, Itga11, SFRP2, DAAM2, and NKD2 effects; however, the depressing effect was higher for AA compared to LA. The previous results were confirmed through Western blotting, which showed that 50 µM LA and AA significantly reduced DAAM2 and SFRP2 protein levels compared to the control. Regarding RNA sequencing results, LA and AA increased the number of differentially expressed (DE) Mt-rRNA and snoRNA; however, the numbers of lncRNA detected decreased compared to the control. Our findings demonstrate that high and moderate LA and AA concentrations reduce primary myoblast proliferation and differentiation. Also, they highlight novel biomarkers and regulatory factors to improve our understanding of how the nutrition of fatty acids can control and modulate the myogenesis and differentiation process through different biomarker families.

The effect of HIV and mpox co-infection on clinical outcomes: Systematic review and meta-analysis.

INTRODUCTION: Co-infection with HIV and mpox is a significant issue for public health because of the potential combined impact on clinical outcomes. However, the existing literature lacks a comprehensive synthesis of the available evidence. The purpose of this meta-analysis is to provide insight into the impact of HIV and mpox co-infection on clinical outcomes. METHODS: We systematically searched major electronic databases (PubMed, Embase, Cochrane Central, and Web of Science) for pertinent studies published up to June 2023. Included were studies that described the clinical outcomes of people who had both mpox and HIV. We performed the analysis using OpenMeta and STATA 17 software. RESULTS: With an overall number of participants of 35 207, 21 studies that met the inclusion criteria were considered. The greatest number of the studies (n = 10) were cohort designs, with three being cross-sectional and eight being case series studies. The meta-analysis found that people who had both HIV and mpox had a higher hospitalization rate than those who only had mpox (odds ratio [OR] 1.848; 95% confidence interval [CI] 0.918-3.719, p = 0.085, I2 = 60.19%, p = 0.020). Furthermore, co-infected patients had higher mortality rates than those who did not have HIV co-infection (OR 3.887; 95% CI 2.272-6.650, p < 0.001). Meta-regression analysis showed that CD4 levels can significantly predict the risk of hospitalization (p = 0.016) and death (p = 0.031). DISCUSSION: HIV causes immunosuppression, making it difficult for the body to mount an effective immune response against pathogens such as mpox. Individuals who are co-infected are at a higher risk of severe disease and death, according to our findings. Although hospitalization rates did not differ significantly between the two groups, it is critical to prioritize interventions and improve management strategies tailored specifically for people living with HIV. CONCLUSION: This meta-analysis provides substantial evidence that HIV and mpox co-infection has a negative impact on clinical outcomes. Co-infected individuals had higher hospitalization and significantly higher mortality rates. These findings highlight the significance of early diagnosis, prompt treatment initiation, and effective management strategies for people living with HIV and mpox.

Pulmonary metastatectomy in pediatric cancer patients at National Cancer Institute, Egypt: prognostic factors and outcome.

BACKGROUND: Metastatic tumors account for 80% of all lung tumors in children. Wilms tumour and osteosarcoma are the most tumors of childhood that produce lung metastases. The aim of the current study is to assess the prognostic factors of pulmonary metastatectomy in pediatric solid tumours as age, number, size, site,laterality, resectability of pulmonary nodules, and number of Thoracotomies. Calculate overall survival among patients who underwent pulmonary metastatectomy. METHODS: It is a retrospective study including all pediatric patients with metastatic solid tumors to lungs treated at pediatric oncology department, National Cancer Institute, Cairo University from 2008 to 2014. Fifty-five patients were included, 43 (78.2℅) patients of them had Osteosarcoma. RESULTS: Thirty (54.5℅)patients were male. The mean age was 15 years ranging from (4.5- 23) years. The site of primary disease was at lower limbs in 43 (78.2%) patients. All patients underwent complete surgical resection of the primary disease with negative margin, 22(51.1%) of the osteosarcoma patients did amputation with tumor necrosis less than 90%. All patients received chemotherapy and only 9 received radiation therapy. The patients were classified into four groups according to time of diagnosis of pulmonary metastasis: at time of diagnosis in 13 (21.8%) patients, within treatment in 16 (30.9%) patients, within first year follow up in 18 (32.7%) patients and detected late in 8 (14.5%) patients. Bilateral lung metastasis diagnosed by CT chest were detected in 42 (76.4%) patients. Size of metastatic nodules was ranging from (0.5 to 10 cm) with mean 3.4 cm. Number of metastatic nodules was ranging from (1 to 28) median 4.Metastatic complications were detected in 19 patients. 5-year OS was 74.8% in the study group, and 68% in osteosarcoma patients. Effect of prognostic factors as sex, time of respectability, laterality, tumor necrosis of the 1ry disease, Timing of lung metastasis, size and site of the primary, Surgical approach of metastatectomy, postoperative complications on overall survival of the studied patients was done with significant P-value of tumor necrosis of the 1ry disease and Timing of lung metastasis 0.017, 0.001 respectively. CONCLUSION: Resection of pulmonary metastases of pediatric solid tumours is a safe and effective treatment that offers better survival.

How much time do surgeons spend operating?

BACKGROUND: Worldwide, there is significant variation in the amount of time surgeons spend performing elective surgery. The degree of variation is unknown. The aim of this study was to assess the variation in amount of time that surgeons spend operating worldwide. METHODS: An anonymised electronic survey was sent via email to members of The Upper Gastrointestinal Surgeons (TUGS) and shared via social media. The questionnaire consisted of demographic details (age, gender, country of practice), scope of practice (full time/less than full time; private/public sector), experience and average number of days the surgeon spends performing elective surgery. RESULTS: A total of 225 predominantly general/upper GI surgeons from 47 countries responded. Worldwide, the median number of days that surgeons spend performing elective surgery is 2 days a week. There was significant variation across countries/continents: UK 1 day; North America 2.5 days; Europe 3 days; Asia 2 days; Africa 2 days; South America 1 day; Oceania 1 day (p < 0.0001). All surgeons worldwide preferred to spend 3 days a week performing elective surgery except UK surgeons who desired 2 days a week. CONCLUSION: There is significant variation in the amount of time that surgeons spend performing elective surgery worldwide. Results of this study could inform public expectations and trainee surgeons on ideal opportunities for training. Reasons for the wide variation could be explored.

Utilization of the internal mammary perforators as the recipient vessels for microsurgical breast reconstruction: A systematic review and meta-analysis of the literature.

BACKGROUND: The selection of reliable recipient vessels is essential for successful free tissue transfer. The use of internal mammary intercostal perforators (IMAPs), instead of the internal mammary vessels as the recipient vessels, has been described in breast reconstruction. Debates exist regarding the reliability of these perforators as recipient vessels because of their variability in location and caliber. The aim of this paper was to conduct a systematic literature review and meta-analysis to determine the reliability of the IMAPs as recipient vessels. METHODS: A systematic literature review was performed on the "PubMed," "Medline," "Ovid," and "Cochrane library" databases for articles published from January 1990 to March 2021. Exclusion criteria were non-English studies, reports with case number less than 5, cadaveric or animal studies, and studies with incomplete postoperative outcomes. The reliability of using IMAPs for breast reconstruction was determined by assessing the reported rates of partial or complete flap failure and other complications (fat necrosis, skin necrosis, and requirement for revision surgery). RESULTS: Three hundred and sixteen cases in 13 studies were included for further analysis with more than 85% of the IMAPs suitable for anastomosis being located in the second and third intercostal spaces. Partial or total flap failure was reported in three of 316 patients (0.95%). The rate of other complications such as fat necrosis, skin necrosis, and requirement for revision surgery were all less than 5%. CONCLUSION: With deliberate preoperative planning, delicate perioperative manipulation, and meticulous microvascular anastomosis, the internal mammary perforators can be used as reliable recipient vessels in microvascular breast reconstruction.

The Coronavirus Anxiety Scale: Cross-national measurement invariance and convergent validity evidence.

Coronavirus Anxiety Scale (CAS) is a widely used measure that captures somatic symptoms of coronavirus-related anxiety. In a large-scale collaboration spanning 60 countries (Ntotal = 21,513), we examined the CAS's measurement invariance and assessed the convergent validity of CAS scores in relation to the fear of COVID-19 (FCV-19S) and the satisfaction with life (SWLS-3) scales. We utilized both conventional exact invariance tests and alignment procedures, with results revealing that the single-factor model fit the data well in almost all countries. Partial scalar invariance was supported in a subset of 56 countries. To ensure the robustness of results, given the unbalanced samples, we employed resampling techniques both with and without replacement and found the results were more stable in larger samples. The alignment procedure demonstrated a high degree of measurement invariance with 9% of the parameters exhibiting noninvariance. We also conducted simulations of alignment using the parameters estimated in the current model. Findings demonstrated reliability of the means but indicated challenges in estimating the latent variances. Strong positive correlations between CAS and FCV-19S estimated with all three different approaches were found in most countries. Correlations of CAS and SWLS-3 were weak and negative but significantly differed from zero in several countries. Overall, the study provided support for the measurement invariance of the CAS and offered evidence of its convergent validity while also highlighting issues with variance estimation.
