ABSTRACT

<b>Background and Objective:</b> The RVF virus cause diseases in newborn puppies, kittens, sheep, goats, cattle, camels, buffaloes and also humans. The RVF disease was first detected among livestock by veterinary officers. The disease causes abortions in animals. The goal of this study was to evaluate the immune response and the haematological profile associated with inactivated RFV vaccine locally produced in Egypt in young puppies and sheep. <b>Materials and Methods:</b> Through vaccination, both young puppies and sheep with local produced inactivated RVF vaccine with 2 doses with 2 weeks interval and evaluate the immune response by SNT and ELISA as well as haematological parameters at 0, 7, 14, 21 and 28 days post-vaccination. The variance between vaccinated groups and also non-vaccinated groups were compared by using a one-way Analysis of Variance (ANOVA). <b>Results:</b> The findings showed that young puppies had a strong response to antibodies after two doses of the RVF vaccine within the 2 week interval. The neutralization indices (NI) values in young puppies at different periods after RVF vaccination reported the value of 1.08±0.03, 1.23±0.04, 1.30±0.03 and 1.45±0.02 after 7, 14, 21 and 28 days post-vaccination, respectively. Parallel to this the ELISA OP values were 0.30±0.00, 0.39±0.03, 0.52±0.05 and 0.75±0.02 after 7, 14, 21 and 28 days post-vaccination, respectively. Nearly similar immune response was noticed in sheep with NI values of 1.15±0.02, 1.27±0.02, 1.42±0.05 and 1.55±0.03 at 7, 14, 21 and 28 days post-vaccination, respectively. In the same site the ELISA OP values were 0.34±0.00, 0.47±0.01, 0.68±0.00, 0.77±0.00. After 7, 14, 21 and 28 days post-vaccination respectively that are also similar to that in puppies. The haematological profile reported a significant decrease after the 1st week followed by a transient increase after booster dose at 2nd week except for the monocytes that increase after 1st week then decreases after 2nd week post-vaccination. <b>Conclusion:</b> Young puppies are similar to sheep in developing antibodies after vaccination with the RFV vaccine with no statistically significant effect within different batches. In addition, ELISA can replace the SNT for evaluation of the immune response. Young puppies are quite equal to sheep for the illustration of neutralizing antibodies for RFV vaccine. Sero-negative puppies can be easily obtained because dogs are not included in the vaccination program of RVF and so they can be used as a good model to determine the efficacy of the RVF vaccine.

ABSTRACT

<b>Background and Objective:</b> There is ample evidence that the consumption of fruits and vegetables, with a high content of secondary metabolites, favours better human health. In the same sense, the application of organic fertilizers has favoured the content of phenolic compounds and a greater antioxidant capacity in various crops. Factoring that the application of Vermicompost (VC) increases the nutritional quality of plants. This research determined the content of soluble solids, biochemical components and the antioxidant capacity of the melon fruits (<i>Cucumis melo</i> L.) developed under shade net conditions with VC as a source of fertilization. <b>Materials and Methods:</b> During the 2020 spring-summer season, a hybrid melon Honeydew type was grown under five mixtures of VC: River sand (RS), with ratios 0:1, 1:1, 1:2, 1:3 and 1:4. Nutrient Steiner solution was applied only in the first mixture (control) while VC was used as an organic nutrient for all other mixtures. The five formulated mixtures, with five replications, were randomly distributed. The total phenolic content, total flavonoids, antioxidant capacity and the total soluble solids of the melon fruit were determined. Data obtained were statistically analyzed by analysis of variance and means were compared by Tukey 0.05 test. <b>Results:</b> The ANOVA indicates that no statistical differences were registered for any of the variables under study, however, the levels of the parameters were high. <b>Conclusion:</b> VC treatment of melon fruit is proven to be a promising source of nutrients to plants increasing their natural antioxidants and content of soluble solids.

ABSTRACT

BACKGROUND: Recent work has demonstrated multiple measures of citation-based scholarly activity. Measures including Hirsch index (h-index), h-index limited to first author manuscripts (hf), h-index limited to first or second author only manuscripts (hs), and g-index have been associated with radiation oncology resident choice of academic versus private practice career. To date, there has been no evaluation of the progression of citation-based scholarly activity during residency.

METHODS: A list of United States radiation oncology residents from the graduating class of 2022 [postgraduate year two (PGY-2) academic year of 2018-2019] was obtained through internet investigation. Citation-based scholarly activity was collected and calculated from searches of the Scopus bibliometric citation database for h-index, hf, hs, and g-index for each resident as previously described. Calculations were derived in June 2018 for the postgraduate year one (PGY-1) year, and in June 2019 for the PGY-2 year. Fisher’s exact test was used for statistical analysis.

RESULTS: Analysis of 195 residents from the 2022 class revealed that the citation-based scholarly activity significantly increased from PGY-1 to PGY-2 for h-index (2.6 to 3.2; P=0.047) and g-index (4.0 to 5.1; P=0.045), but not for hf (1.0 to 1.3; P=0.170) or hs (1.5 to 1.9; P=0.065). Underrepresented minority race/ethnicity (African-American/Hispanic) did not impact the significance of the h-index and g-index findings.

CONCLUSIONS: From the PGY-1 to PGY-2 academic year, residents significantly increased in citation-based academic productivity, with an increase in the proportion of residents with a cited first-or-second author manuscript. Further study is necessary to determine how this trend persists in future years.

ABSTRACT

Ultrahigh and high dimensional data are common in regression analysis for various fields, such as omics data, finance, and biological engineering. In addition to the problem of dimension, the data might also be contaminated. There are two main types of contamination: outliers and model misspecification. We develop an unique method that takes into account the ultrahigh or high dimensional issues and both types of contamination. In this article, we propose a framework for feature screening and selection based on the minimum Lq-likelihood estimation (MLqE), which accounts for the model misspecification contamination issue and has also been shown to be robust to outliers. In numerical analysis, we explore the robustness of this framework under different outliers and model misspecification scenarios. To examine the performance of this framework, we conduct real data analysis using the skin cutaneous melanoma data. When comparing with traditional screening and feature selection methods, the proposed method shows superiority in both variable identification effectiveness and parameter estimation accuracy.

ABSTRACT

BACKGROUND: Women and men with heart failure (HF) and preserved ejection fraction may differ in their clinical characteristics and their response to therapy. The aim of this study was to evaluate the influence of sex on the effects of empagliflozin in patients with HF and preserved ejection fraction enrolled in the EMPEROR-Preserved trial (Empagliflozin Outcome Trial in Patients With Chronic Heart Failure With Preserved Ejection Fraction).

METHODS: The effects of empagliflozin on the primary outcome of cardiovascular death or hospitalization for HF and on secondary outcomes (including total HF hospitalization, cardiovascular and all-cause mortality, and Kansas City Cardiomyopathy Questionnaire scores) were compared in women and men in the overall cohort and in subgroups defined by left ventricular ejection fraction (41%-49%, 50%-59%, and ≥60%). The effects of empagliflozin on physiological measures, including changes in systolic blood pressure, uric acid, hemoglobin, body weight, and natriuretic peptide levels, were also assessed.

RESULTS: Of the 5988 patients randomized, 2676 (44.7%) were women. In the placebo arm, women tended to have lower risk for adverse outcomes, including a lower risk of all-cause mortality (hazard ratio, 0.69 [95% CI, 0.56, 0.84]). Compared with placebo, empagliflozin reduced the risk of cardiovascular death or hospitalization for HF to a similar degree in both sexes (hazard ratio, 0.81 [95% CI, 0.69, 0.96] for men; and hazard ratio, 0.75 [95% CI, 0.61, 0.92] for women; P_interaction=0.54). Sex did not modify the relationship between empagliflozin and outcomes across ejection fraction groups. Similar results were seen for secondary outcomes and physiological measures. Compared with placebo, empagliflozin improved the Kansas City Cardiomyopathy Questionnaire Clinical Summary Score to a similar extent in both sexes (1.38 for men versus 1.63 for women at 52 weeks; P_interaction=0.77); the results were similar for Kansas City Cardiomyopathy Questionnaire overall summary score and total summary score.

CONCLUSIONS: Empagliflozin produced similar benefits on outcomes and health status in women and men with HF and preserved ejection fraction.

ABSTRACT

BACKGROUND: The relationship between vegetable consumption and hypertension occurrence remains poorly characterized in sub-Saharan Africa.

AIM: This study assessed the association of vegetable consumption with odds of hypertension among indigenous Africans.

METHODS: We harmonized data on prior vegetable consumption and hypertension occurrence (defined as one of the following conditions; systolic blood pressure ≥140 or diastolic blood pressure ≥90mmHg or previous diagnosis or use of antihypertensive medications) from 16,445 participants across five African countries (Nigeria, South Africa, Kenya, Ghana and Burkina Faso) from the SIREN and AWI-Gen studies. Vegetable consumption (in servings/week) was classified as ‘low’ (<6). ‘moderate’ (6-11), ‘sufficient’ (12-29) and ‘high’ (≥30). Odds ratios (OR) and 95% confidence interval (CI) of hypertension were estimated by categories of vegetable consumption (using ‘low’ consumption as reference), adjusting for sex, age in years, family history of cardiovascular diseases, education, smoking, alcohol use, physical inactivity, body mass index, diabetes mellitus and dyslipidaemia using logistic regressions at P < 0.05.

RESULTS: The mean age of participants was 53·0 (+/-10·7) years, and 7,552 (45·9%) were males, while 7,070 (42·9%) had hypertension. Also, 6,672(40·6%) participants had ‘low’ vegetable consumption, and 1,758(10·7%) had ‘high’ vegetable consumption. Multivariable-adjusted OR for hypertension by distribution of vegetable consumption (using ‘low’ consumption as reference), were 1·03 (95% CI: 0·95, 1·12) for ‘moderate’ consumption; 0·80 (0·73, 0·88) for ‘sufficient’ and 0·81 (0·72, 0·92) for ‘high’ consumption, P-for-trend <0·0001.

CONCLUSION: Indigenous Africans who consumed at least twelve servings of vegetables per week were less likely to be found hypertensive, particularly among males and young adults.

ABSTRACT

BACKGROUND: Integrating primary prevention into care pathways for older adults is a core strategy of healthy ageing, but evidence remains limited. We aimed to determine whether incorporating a multidomain intervention into primary health care could improve standard value-based health outcomes and quality of life.

METHODS: For this Taiwan Integrated Geriatric Care (TIGER) study, a pragmatic randomised controlled trial, we recruited community-dwelling outpatients aged 65 years or older with at least three chronic medical conditions. We excluded people with malignancies undergoing chemotherapy, people with a life expectancy of less than 12 months, or people who were insufficiently able to communicate with study staff. Participants were randomly assigned (1:1) to usual care or to the integrated multidomain intervention using block randomisation. The integrated multidomain intervention entailed 16 2-h sessions per year, comprising communal physical exercise, cognitive training, nutrition and disease education, plus individualised treatment by specialists in integrated geriatric care. The primary outcome was changes from baseline quality of life, based on 36-item Short Form Health Survey (SF-36) scores, at 3, 6, 9, and 12 months. Intervention effects were analysed per protocol using a generalised linear mixed model. This trial is registered with ClinicalTrials.gov, NCT03528005.

FINDINGS: Between June 25, 2018, and Feb 15, 2019, 628 participants were screened, of whom 398 were assigned to the integrated multidomain intervention (n=199) or to usual care (n=199). 335 (84%) participants completed the 12-month follow-up. Compared with the usual care group, the integrated multidomain intervention group had significantly higher mean SF-36 physical component scores across all timepoints (overall difference 0·8, 95% CI 0·2-1·5; p=0·010), but differences at 3, 6, 9, and 12 months did not reach statistical significance. The SF-36 mental component scores did not differ significantly overall, but were significantly higher in the integrated multidomain intervention group at the 12-month follow-up (55·3 [SD 7·6] vs 57·2 [7·0]; p=0·019). No serious adverse events occurred.

INTERPRETATION: Incorporating multidomain interventions into integrated health care improved quality of life. Our standardised protocol is amenable to inclusion in policies to promote value-based care and healthy ageing.

ABSTRACT

Aim: The current study compared the effectiveness of remote electrical neuromodulation (REN) to that of standard-care medications for acute treatments of migraine, using a within-subjects design. Materials & methods: Post-hoc within-subject analysis was performed on data from 78 adult chronic migraine patients who participated in a clinical trial with REN, on four end points: single-treatment pain relief, single-treatment pain freedom, consistency of pain relief and consistency of pain freedom. Results: No statistical differences were found between REN and the tested medications, in any of the effectiveness outcomes: single-treatment pain relief p = 0.056, single-treatment pain freedom p = 0.532, consistency of pain relief p = 0.369, consistency of pain freedom p = 1.00. Conclusion: The results suggest that REN may provide an effective non-pharmacological alternative for standard care abortive medications in individuals impacted by chronic migraine.

ABSTRACT

BACKGROUND: COVID-19 is a newly discovered infectious disease that spread and caused a global health problem. Medical students, especially those in clinical stages are among groups exposed to the disease. The study aimed to show the impact of social distancing on the mental health of Iraqi medical students.

METHOD: A convenient sampling technique involved 105 participants was obtained through a questionnaire. The participants were from all stages of College Of Medicine. Questions were regarding the mental health status of the students, which included sleeping hours, nightmares, eating habits, weight problems, relationship with the family, starting to have bad habits, memory loss, attention problems, irritability, and study rank affect.

RESULTS: Of about 105 participants, 64 (60.9%) of them were females and 41 (39.1%) were males. The mean age of the participants was (21.26 ± 1.065) ranging from 19 to 24 years. Feeling stressful when hearing news about COVID-19″ found in 82 (78.1%) of the participants. A high statistical significant difference (p = 0.035) among feeling isolated. About 77 (73.3%) of the participants had become easily irritable and angry. About 82 (78.1%) student started for having calculation problems. The stress with sleeping hours (p = 0.019), sleeping disturbance (p = 0.022), eating habit (p = 0.015), weight problems (p = 0.002), fear of familiar places (p = 0.004), recent memory loss (p = 0.034) and being easily irritable or angry (p = 0.0001), revealed a statistical significant association, respectively.

CONCLUSION: COVID-19 news and social distancing had made medical students more stressed and irritable, affecting their sleeping hours and pattern with a general tendency for weight gain and recent memory loss in stressful students.

ABSTRACT

BACKGROUND: Hidradenitis suppurativa (HS) is associated with substantial morbidity. Few studies have addressed the natural history and mortality rates associated with HS. A higher risk of cardiovascular death in patients with HS has been reported. We investigated whether patients with HS have an increased overall risk of death compared with age- and gender-matched referents.

METHODS: We performed a retrospective cohort study of residents of Olmsted County, Minnesota, with incident HS between January 1, 1980, and December 31, 2008, and age- and gender-matched referents. The main outcomes and measures were the overall and cause-specific risks of death.

RESULTS: We identified 226 incident cases of HS and 678 age- and gender-matched referents among Olmsted County residents during the study period. Compared to referents, patients with HS had a significantly higher risk of all-cause death (hazard ratio [HR, 2.48; 95% CI, 1.53-4.03, P < 0.001) and cardiovascular- or cerebrovascular-related death (HR, 2.85; 95% CI, 1.10-7.40, P = 0.03). However, these risks were attenuated by adjusting for smoking history: all-cause HR, 1.65 (95% CI, 0.97-2.82, P = 0.07) and cardiovascular- or cerebrovascular-related HR, 2.03 (95% CI, 0.71-5.81, P = 0.18). The 71% of patients were former or current smokers at the time of HS diagnosis.

CONCLUSIONS: Hidradenitis suppurativa patients have a substantially increased risk of death from any cause, including cardiovascular or cerebrovascular causes; the risk is especially dependent on smoking history.
