RESUMEN

Psoriasis is a chronic, immune-mediated, hyperproliferative skin disease. Etiopathogenesis of psoriasis is not well understood. Plexin B2 was found to have effects on CD100-mediated T-cell morphology and expressed in the immune system. It may play a role in the pathogenesis of psoriasis. To assess the tissue level of plexin-B2 and plexin B2 related gene polymorphism which is signal regulatory protein gamma (SIRPγ-rs71212732) in psoriatic patients before and after NB-UVB, acitretin therapy alone or in combination and to detect correlation between level of tissue plexin B2 and disease severity and improvement. This single blinded randomized controlled trial was carried on 50 psoriatic patients and 50 healthy controls. Psoriasis Area and Severity Index score (PASI) was used to evaluate the disease severity. Tissue plexin-b2 level was measured using ELISA and SIRPγ-rs71212732 (T\C) was assessed using TaqMan™ assays and real-time PCR. A significant lower tissue plexin-B2 level was observed in control group (2.9 ± 0.6 pg/g) than cases (25.8 ± 2.8, pg/g) (p < 0.001). Also, a significantly higher tissue plexin-B2 level was observed in sever psoriasis (32.7 ± 3.8 pg/ml) in than moderate psoriasis (13.6 ± 2.1 pg/ml, p = 0.001). Tissue plexin B2 was positively correlated with diseases severity. Significantly higher (TC& TT) genotypes and mutant (C) allele among patients compared to the controls, p < 0.001 for all. Tissue plexin-b2 level was high in psoriasis vulgaris with positive correlation with disease severity and decreased after treatment. This may indicate a role of plexin-b2 in psoriasis vulgaris pathogenesis.

RESUMEN

BACKGROUND: Psoriasis is an autoimmune disease which has an effect on the joints and skin. Tumor Necrosis Factor-Like Weak Inducer of Apoptosis (TWEAK) is a multi-functional cytokine which regulates the cellular processes and has been related to a variation of conditions. OBJECTIVES: To measure the level of serum TWEAK in psoriatic diseased persons and its relationship to the PASI score pre- and post-therapy with narrowband ultraviolet B phototherapy (NB-UVB) and methotrexate (MTX). METHODS: This randomized controlled trial was conducted on 40 patients and 20 healthy persons as controls. Patient Group was randomly subdivided to two groups. The 1st group consisted of 20 patients who received NB-UVB treatment. The 2nd group included 20 MTX-treated candidates. Blood samples were drawn from patients in order to detect serum TWEAK levels using ELISA. The research was registered on Clinical Trials Registration: RCT approval numbers: NCT0481191. RESULTS: The mean PASI score percent improvement after 12 weeks of treatment was higher in the MTX group (90%) than NB-UVB group (60%). The serum TWEAK level at baseline was 60.47 ± 12.6 pg/mL in NB-UVB group and 54.69 ± 21.7 pg/mL in MTX group which reduced to 24.93 ± 17.6 pg/mL and 32.13 ± 23.6 pg/mL, respectively (p < 0.001), after 12 weeks of treatment. There was a positive correlation between the serum levels of TWEAK and severity of PASI score (r = 0.399, p = 0.014). CONCLUSION: TWEAK grades in psoriasis are substantially higher than in controls. TWEAK levels were dramatically reduced during NB-UVB and MTX treatment. TWEAK may have a potential sign for psoriasis diagnosis and prognosis.

RESUMEN

During the COVID-19 pandemic, major challenges are facing pediatric cancer centers regarding access to cancer centers, continuity of the anti-cancer therapy, hospital admission, and infection protection precautions. Pediatric oncologists actively treating children with cancer from 29 cancer centers at 11 countries were asked to answer a survey from May 2020 to August 2020 either directly or through the internet. COVID-19 pandemic affected the access to pediatric cancer care in the form of difficulty in reaching the center in 22 (75.9%) centers and affection of patients' flow in 21 (72.4%) centers. Health care professionals (HCP) were infected with COVID-19 in 20 (69%) surveyed centers. Eighteen centers (62%) modified the treatment guidelines. Care of follow-up patients was provided in-hospital in 8(27.6%) centers, through telemedicine in 10 (34.5%) centers, and just delayed in 11 (38%) centers. Pediatric oncologists had different expectations about the future effects of COVID-19 on pediatric cancer care. Seventy-six percent of pediatric oncologists think the COVID-19 pandemic will increase the use of telemedicine. Fifty-five percent of pediatric oncologists think if the COVID-19 pandemic persists, we will need to change chemotherapy protocols to less myelosuppressive ones. Collaborative studies are required to prioritize pediatric cancer management during COVID-19 era.

RESUMEN

BACKGROUND: Depression affects about 3.8% of the world's population. Although marriage may contribute to subjective well-being, some marital variables could increase women's risk for depression. This study aimed to determine the prevalence of depressive symptoms and their correlates among married females attending primary healthcare facilities. METHODS: A cross-sectional study was conducted on a purposive sample of 371 married women at the primary healthcare centers, Assiut Governorate, Upper Egypt. In this study, an interviewer-administered questionnaire was used for data collection. Depressive symptoms were assessed using the Patient Health Questionnaire-9 (PHQ-9) and marital satisfaction using the ENRICH Marital Satisfaction Scale (EMS). Standardized measurements of weight and height were performed. RESULTS: According to the PHQ-9 diagnostic criteria, the prevalence of depressive symptoms among the studied married females was 30.2%. The significant predictors of depressive symptoms were advanced husbands' ages, living with an extended family, exposure to spousal verbal violence, high body weight, and low marital satisfaction levels. CONCLUSIONS: Approximately one-third of married Egyptian women experienced depressive symptoms. In addition to high body weight, some social and marital factors contributed to the increase in women's vulnerability to depressive symptoms. Egyptian primary healthcare physicians should be trained to identify females with depressive symptoms and refer them to specialists if need be. To combat depression in women, it may be helpful to construct qualified marital counseling centers. This may improve marital satisfaction, decrease the negative consequences of spousal violence, and ensure the value of independence for new families.

RESUMEN

BACKGROUND: Internet addiction has been a topic of discussion in the academic literature for many years. As of April 2020, about 60 % of the world's population (nearly 4.6 billion people) were active internet user in their early adulthood. The prevalence among adolescent and college students ranged from 0.9 % to 33 %. The current study aimed to explore internet addiction's prevalence and correlates among undergraduate medical students at an Egyptian university. Also, to assess the relationship between internet addiction, depression symptoms, and socioeconomic status. METHODS: A cross-sectional study of 321 undergraduate medical students at Assiut University using the Internet Addiction Scale, Patient Health Questionnaire, and Family Affluence Scale. RESULTS: About 9 % of the study participants screened positive for internet addiction. The most important determinants among medical students were sex, mother's employment status, family affluence, depressive symptoms, and unmonitored internet access. LIMITATIONS: We did not investigate another psychiatric disease, daily time of internet usage, most frequent time of usage, type of internet usage, and cost of use. CONCLUSIONS: Internet Addiction is an important psychological problem affecting about 9 % of Assiut university medical students during their undergraduate stage, which may interfere with their lives and studies. Students with lower Internet addiction rates were female students whose mothers were employed, lived in a low affluence family, had fewer depressive symptoms, and had unmonitored internet privacy.

RESUMEN

The chemical constituents of the nonpolar fractions of the bamboo shoot skin Phyllostachys heterocycla were extensively studied. The phytochemical study was divided into two parts: the first deals with isolation of the chemical constituents using different chromatographic techniques that resulted in isolation of four compounds. The chemical structures of the pure isolated compounds were elucidated using different spectroscopic data. The second part deals with identification of the rest of the constituents using the GC technique. Additionally, both crude extract and the pure isolated compounds were investigated for cytotoxic activity. One of the isolated compounds; namely glyceryl 1-monopalmitate showed highly promising effect against the MCF-7 cells with (IC50 = 19.78 µM) compared to 5-FU (26.98 µM), and it remarkably stimulated apoptotic breast cancer cell death with 31.6-fold (16.13% compared to 0.51 for the control) at pre-G1 and G2/M-phase cell cycle arrest and blocked the progression of MCF-7 cells. Moreover, the identified compounds especially 1 were found to have high binding affinity towards both TPK and VEGFR-2 through the molecular docking studies which highlight its mode of action. HighlightsChemical profiling of Phyllostachys heterocycla bark nonpolar extract was fully identified.Glyceryl 1-monopalmitate showed highly promising effect against the MCF-7 cells with (IC50 = 19.78 µM) compared to 5-FU (26.98 µM).Glyceryl 1-monopalmitate significantly stimulated apoptotic breast cancer cell death with 31.6-fold by arresting cell cycle at G2/M and preG1 phases.Molecular docking simulation showed good binding affinities towards TPK and VEGFR-2 proteins.Communicated by Ramaswamy H.

RESUMEN

BACKGROUND: Succinylcholine is a preferred muscle relaxant for rapid sequence intubation. Postoperative myalgia (POM) is one of its commonest adverse effects with unknown pathogenesis. Various modalities were examined to reduce POM. We hypothesized that duloxetine may reduce the incidence and severity of fasciculation or succinylcholine-induced POM in outpatient surgeries. METHODS: This randomized double-blinded trial involved controlled 70 adult participants scheduled for elective direct microlaryngoscopic surgeries. Before induction of general anesthesia by 2 h, 35 patients received duloxetine 30 mg orally (group D) and 35 patients received similar oral starch placebo capsules (group C). Fasciculations, POM, sedation score, time to first rescue analgesia, total analgesic consumption 24 h after surgery, patients' satisfaction, and adverse effects were recorded. RESULTS: Incidence of fasciculation was 77.1% and 94.3% in groups D and C (p value = 0.04), whereas its severity was not significant between groups (p value = 0.09). Incidence and severity of POM were significantly lower in group D (p values = 0.004 and 0.021). Positive correlation was recorded between fasciculations and POM scores (r = 0.732 and p < 0.001). Time required for first analgesia was prolonged in group D (p value < 0.001) with less total analgesic consumption (p value = 0.039). The potassium and creatine kinase levels showed significant differences between both groups after 30 min and 24 h, respectively (p value < 0.05). Sedation scores and patients' satisfaction were better in duloxetine group (p value < 0.05) with no severe complications. CONCLUSIONS: Preoperative oral duloxetine 30 mg administration decreased incidence and severity of succinylcholine-related muscle POM and fasciculations. It was also effective in reducing postoperative rescue analgesic requirement with better patients' satisfaction and no serious adverse effects.

RESUMEN

BACKGROUND: Fragility hip fracture is a common condition with serious consequences. Most outcomes data come from Western and Asian populations. There are few data from African and Middle Eastern countries. OBJECTIVE: The primary objective was to describe mortality rates after fragility hip fracture in a Level-1 trauma centre in Egypt. The secondary objective was to study the causes of re-admissions, complications, and mortality. METHODS: A prospective cohort study of 301 patients, aged > 65 years, with fragility hip fractures. Data collected included sociodemographic, co-morbidities, timing of admission, and intraoperative,ostoperative, and post-discharge data as mortality, complications, hospital stay, reoperation, and re-admission. Cox regression analysis was conducted to investigate factors associated with 1-year mortality. RESULTS: In-hospital mortality was 8.3% (25 patients) which increased to 52.8% (159 patients) after one year; 58.5% of the deaths occurred in the first 3-months. One-year mortality was independently associated with increasing age, ASA 3-4, cardiac or hepatic co-morbidities, trochanteric fractures, total hospital stay, and postoperative ifection and metal failure. CONCLUSION: Our in-hospital mortality rate resembles developed countries reports, reflecting good initial geriatric healthcare. However, our 3- and 12-months mortality rates are unexpectedly high. The implementation of orthogeriatric care after discharge is mandatory to decrease mortality rates.

RESUMEN

BACKGROUND: burnout syndrome is a serious and growing problem among medical staff. Its adverse outcomes not only affect health-care providers' health, but also extend to their patients, resulting in bad-quality care. The COVID-19 pandemic puts frontline health-care providers at greater risk of psychological stress and burnout syndrome. OBJECTIVES: this study aimed to identify the levels of burnout among health-care professionals currently working at Assiut University hospitals during the COVID-19 pandemic. METHODS: the current study adopted an online cross-sectional design using the SurveyMonkey® website for data collection. A total of 201 physicians were included and the Maslach Burnout Inventory (MBI) scale was used to assess the three burnout syndrome dimensions: emotional exhaustion, depersonalization, and reduced personal accomplishment. RESULTS: about one-third, two-thirds, and one-quarter of the respondents had high emotional exhaustion, high depersonalization, and low personal accomplishment, respectively. Younger, resident, and single physicians reported higher burnout scores. The personal accomplishment score was significantly higher among males. Those working more than eight hours/day and dealing with COVID-19 patients had significantly higher scores. CONCLUSION: during the COVID-19 pandemic, a high prevalence of burnout was recorded among physicians. Age, job title, working duration, and working hours/day were significant predictors for burnout syndrome subscale results. Preventive and interventive programs should be applied in health-care organizations during pandemics.

RESUMEN

BACKGROUND: Postpartum depression (PPD) is highly prevalent with a major impact on the mother and child health. We aimed to determine the prevalence of PPD in primary health care centres which provide vaccinations services to infants in Assiut city and to evaluate the possible risk factors associated with PPD. METHODS: In this multicentre study, 257 mothers attended three primary health care centres for immunization of their babies were recruited from January 2019 to January 2020. All participants were evaluated for socio-demographic features, Family affluence scale (FAS), Edinburgh Postnatal Depression Scale (EPDS) and associated risk factors. RESULTS: The mean age of the participants was 27.98 ± 4.7. About half of the mothers and their husbands had low education level. Most of the families (89%) have low socioeconomic scale (SES). About (33.5%) women were found to have possible PPD. In the logistic regression analysis, SES, history of depression, history of PPD, history of stressful conditions, familial support, unwanted pregnancy, and male preference were significant statistical in PPD (p < 0.05). LIMITATIONS: We did not investigate the medical and psychological problems during antenatal care. Also, we did not assess relation of the type of delivery and medical problems during delivery on the postnatal care. CONCLUSIONS: PPD was prevalent in 33.5% The possible risk factors of PPD were low SES, history of depression, history of PPD, history of stressful conditions, familial support, unwanted pregnancy, and male preference.

RESUMEN

Different extracts of the Bamboo shoot skin Phyllostachys heterocycla var. pubescens were screened against panel of cancer cell lines and normal one. The cell viability results exhibited that the ethyl acetate extract showed the least vitality percentage of 2.14% of HepG2 cells. Accordingly, it was subjected to chromatographic separation, which resulted in the isolation of a new natural product; 7-hydroxy, 5-methoxy, methyl cinnamate (1), together with four known compounds. The structures of the pure isolated compounds were deduced based on different spectroscopic data. The new compound (1) was screened against the HepG2 and MCF-7 cells and showed IC50 values of 7.43 and 10.65 µM, respectively. It induced apoptotic cell death in HepG2 with total apoptotic cell death of 58.6% (12.44-fold) compared to 4.71% in control by arresting cell cycle progression at the G1 phase. Finally, compound 1 was validated as EGFR tyrosine kinase inhibitor in both enzymatic levels (IC50 = 98.65 nM compared to Erlotinib (IC50 = 78.65 nM). Finally, in silico studies of compound 1 through the molecular docking indicated its high binding affinity towards EGFR protein and the ADME pharmacokinetics indicated it as a drug-like.

RESUMEN

INTRODUCTION: Despite global efforts to contain the illness, COVID-19 continues to have severe health, life, and economic repercussions; thus, maintaining vaccine development is mandatory. Different directions concerning COVID-19 vaccines have emerged as a result of the vaccine's unpredictability. AIMS: To study the determinants of the attitudes of healthcare workers (HCWs) to receiving or refusing to receive the vaccine. METHODS: The current study adopted an interviewed questionnaire between June and August 2021. A total of 341 HCWs currently working at Assiut University hospitals offered to receive the vaccine were included. RESULTS: Only half of the HCWs (42%) accepted the COVID-19 vaccine. The most common reason that motivated the HCWs was being more susceptible than others to infection (71.8%). On other hand, the common reasons for refusing included: previously contracted the virus (64.8%); did not have time (58.8%); warned by a doctor not to take it (53.8%). Nearly one-third of nonaccepting HCWs depended on television, the Internet, and friends who refused the vaccine for information (p < 0.05). In the final multivariate regression model, there were six significant predictors: sex, job category, chronic disease, being vaccinated for influenza, and using Assiut University hospital staff and the Ministry of Health as sources of information (p < 0.05). CONCLUSION: Misinformation and negative conceptions are still barriers against achieving the desired rate of vaccination, especially for vulnerable groups such as HCWs.

RESUMEN

Phytochemical screening of nonpolar fractions from the methanol extract of the Bamboo shoot skin Phyllostachys heterocycla var. pubescens resulted in the isolation of a new sterol-glucoside-fatty acid derivative (6'-O-octadeca-8'',11''-dienoyl)-sitosterol-3-O-ß-d-glucoside (1), together with six known compounds. The chemical structures of the pure isolated compounds were deduced based on different spectral data. The isolated compounds were assessed to determine their cytotoxic activity, and the results were confirmed by determining their apoptotic activity. Compound 1 was more cytotoxic against the MCF-7 cells (IC50 = 25.8 µM) compared to Fluorouracil (5-FU) (26.98 µM), and it significantly stimulated apoptotic breast cancer cell death with 32.6-fold (16.63% compared to 0.51 for the control) at pre-G1 and G2/M-phase cell cycle arrest and blocked the progression of MCF-7 cells. Additionally, RT-PCR results further confirmed the apoptotic activity of compound 1 by the upregulation of proapoptotic genes (P53; Bax; and caspases 3, 8, and 9) and downregulation of the antiapoptotic genes (BCL2). Finally, the identified compounds, especially 1, were found to have high binding affinity towards both tyrosine-specific protein kinase (TPK) and vascular endothelial growth factor receptor (VEGFR-2) through the molecular docking studies that highlight its mode of action.

RESUMEN

BACKGROUND: Planar-based measurements of lesions in metastatic melanoma have limitations in estimating tumor burden of a patient and in predicting response to treatment. Volumetric imaging might add predictive value to Response criteria in Solid Tumor (RECIST)-measurement. Based on clinical observations, we explored the association between baseline tumor volume (TV) and duration of treatment with dabrafenib in patients with metastatic melanoma. We have also explored the prognostic value of TV for overall survival (OS) and progression free survival (PFS). METHODS: This is a retrospective, chart-review of primary source documents and medical imaging of a cohort of patients participating in the BRF112680 phase 1 clinical trial at the Prince of Wales Hospital. TV was quantified by contouring all the measurable baseline target lesions in the standard manner for radiation planning using Voxxar™ software. We used Cox regression models to analyse associations between TV and duration of treatment with dabrafenib and between TV, PFS and OS. RESULTS: Among 13 patients of BRAF 112680 trial, 10 were included in the retrospective analysis. Target lesion sum volume ranged from 0.3 to 1065.5 cm3 (cc), with a median of 27.5 cc. The median PFS and OS were 420 days (range 109-1765) and 1680 days (range 390-2940), respectively. The initial TV was inversely correlated with duration of treatment with dabrafenib (rho - 0.6; P 0.03). In multivariate analysis, TV was a predictor for OS (HR 2.81 CI 1.06-6.19) and PFS (8.76 (CI 1.05-43.58). Patients with tumour volume above the median had significantly lower OS of 6-months compared to 56-months survival for patients with smaller volumes; P = 0.019. CONCLUSIONS: TV is a predictor for treatment duration and is prognostic of OS and PFS in patients with metastatic melanoma. These findings need to be validated prospectively in clinical trials.

RESUMEN

BACKGROUND: For children with cleft palates, surgeries at a young age are necessary to reduce feeding or phonation difficulties and reduce complications, especially respiratory tract infections and frequent sinusitis. We hypothesized that dexmedetomidine might prolong the postoperative analgesic duration when added to bupivacaine during nerve blocks. METHODS: Eighty patients of 1-5 years old were arbitrarily assigned to two equal groups (forty patients each) to receive bilateral suprazygomatic maxillary nerve blocks. Group A received bilateral 0.2 mL/kg bupivacaine (0.125%; maximum volume 4 mL/side). Group B received bilateral 0.2 mL/kg bupivacaine (0.125%) + 0.5 µg/kg dexmedetomidine (maximum volume 4 mL/side). RESULTS: The modified children's hospital of Eastern Ontario pain scale score was significantly lower in group B children after 8 hours of follow-up postoperatively (P < 0.001). Mean values of heart rate and blood pressure were significantly different between the groups, with lower mean values in group B (P < 0.001). Median time to the first analgesic demand in group A children was 10 hours (range 8-12 hr), and no patients needed analgesia in group B. The sedation score assessment was higher in children given dexmedetomidine (P = 0.03) during the first postoperative 30 minutes. Better parent satisfaction scores (5-point Likert scale) were recorded in group B and without serious adverse effects. CONCLUSIONS: Addition of dexmedetomidine 0.5 µg/kg to bupivacaine 0.125% has accentuated the analgesic efficacy of bilateral suprazygomatic maxillary nerve block in children undergoing primary cleft palate repair with less postoperative supplemental analgesia or untoward effects.

RESUMEN

Background: Heart failure is the most common cause of hospitalization in elderly patients. It is likely that many of the mechanisms that contribute to reductions in systolic and diastolic function, seen in diabetic patients, place them at an increased risk of heart failure. Diuretic therapy, especially loop diuretics, is the usual way of managing congestion, particularly in volume-overloaded patients. Little is known about the beneficial effect of dapagliflozin when added to loop diuretics in managing patients with decompensated heart failure. Aim: To assess the effect of the addition of dapagliflozin to furosemide in managing decompensated patient with heart failure and reduced left ventricular ejection fraction in terms of weight loss and dyspnea improvement. Patients and Methods: The study included 100 type 2 diabetic patients who were admitted with decompensated heart failure. The study population was randomly divided into two arms. Serum electrolytes and kidney functions were followed up during their hospital stay. Results: With dapagliflozin, there was a statistically significant difference between the two groups regarding the change in body weight and body mass index. The diuresis parameters including urine output, total fluid loss, and fluid balance also showed a statistically significant difference in favor of the use of dapagliflozin, with no significant change in serum potassium or kidney functions. There was significant improvement in patient-reported dyspnea scores with the use of dapagliflozin. Conclusions: Dapagliflozin may provide a new drug option in the treatment of heart failure especially among vulnerable group of diabetics. It had no remarkable effects on serum potassium level and kidney functions. Clinical Trial Registration: www.ClinicalTrials.gov, identifier: NCT04385589.

RESUMEN

Rheumatoid arthritis (RA) is one of the most widespread autoimmune disorders and it has a genetic background with a variety of genes affecting the degradation of the immune system. Along these lines, we assessed the relationship between the BsmI, and FokI VDR polymorphisms and inflammable records identified with infections activity. Such as interleukins (IL-6, IL-8), hypoxia inducible factor-alpha (HIF-α), soluble receptor of advanced glycation end product (sRAGE), oxidized low-density lipoprotein cholesterol (oxLDL), neutrophil gelatinase-associated lipocalin (NGAL) and procollagen N-propeptide of type III collagen (P3NP) and the allelic frequencies of BsmI VDR rs1544410 and FokI VDR rs2228570 polymorphism on the RA. Total of 131 subjects [70 RA patients and 61 age and sex matched apparently healthy controls (HC)] were monitored for inflammatory biomarkers using ELISA. All patients were screened for the BsmI and FokI using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The all biomarkers were significantly higher in RA patients in comparison with HC. There were positive correlations between NGAL, oxLDL and s-RAGE, oxLDL. On BsmI, 'GG' and 'AG' genotypes were significantly associated with high RA activity as well as the frequency of genotypes 'AG & GG" were higher in high activity RA as compared to low RA activity. However on FokI, was observed that in high activity patients the frequency of 'CC' & 'CT' was more prevalent as compared to low activity ones. These outcomes support the immunoregulatory role of vitamin D which is associated with several inflammatory diseases, signifying a credible anti-inflammatory role in perturbation of the RA.

RESUMEN

BACKGROUND AND AIM: Varicocele is one of the most common causes of male infertility. Leptin that has a role in sperm motility may have a role of varicocele. We aimed to study the effect of varicocelectomy on the serum and seminal leptin in patients with asthenozoospermia and the correlation between leptin levels, sperm parameters and varicocele grade. METHODS: Thirty-six male patients with varicocele having isolated asthenozoospermia were included in this study. Thirty normal fertile controls were included. Semen analysis, serum and seminal leptin measurements were performed for all participants at baseline and for patients three months after varicocelectomy. Microsurgical varicocelectomy has been performed for patients. RESULTS: Seminal and serum leptin levels were significantly higher in patients than controls. Seminal leptin was positively correlated with varicocele grade (r = 0.357, p < .05) while no correlation was found between serum leptin varicocele grade (r = 0.056, p = .37). Both seminal and serum leptin were inversely correlated with sperm motility (r = -0.92 and r = -0.87, p < .001; respectively). Seminal and serum leptin were significantly improved after varicocelectomy. CONCLUSION: Varicocele is associated with higher levels of seminal and serum leptin especially in higher grads and this was correlated with negative effects on sperm motility. Leptin levels were significantly decreased after repair.

RESUMEN

BACKGROUND: Various adjuvants were added to intrathecal anaesthetics to improve quality of the block and postoperative analgesia. We hypothesized that intrathecal dexmedetomidine and magnesium sulphate (MgSO4 ) may add similar effects. Our objectives were to compare their effects as adjuvants to intrathecal bupivacaine on postoperative analgesia, stress hormones, sedative properties and the neonatal outcome after caesarean section. METHODS: A randomized double-blind controlled study; 90 parturients were divided into three groups. All patients received intrathecal hyperbaric bupivacaine 12.5 mg. NaCl 0.9% was added to intrathecal block in group C, 5 µg dexmedetomidine in the group D and 50 mg MgSO4 in group M. Visual analogue scale (VAS) score, stress hormones were assessed within the first 12 postoperative hours, sensory block, and neonatal outcome were also assessed. RESULTS: VAS scores were significantly lower in groups D and M. Onset of postoperative pain was significantly prolonged in group D. Time to peak sensory level was shorter in group D. Sedation score was significantly higher in group D only after 30 min of intrathecal block. Although stress hormones increased in all groups during intraoperative and postoperative periods, their levels were significantly lower in group D compared to other groups. No differences were noted regarding neonatal outcomes. CONCLUSION: Intrathecal dexmedetomidine is superior to intrathecal MgSO4 during caesarean section with regard to duration of analgesia, pain severity and stress hormone levels. Dexmedetomidine has a rapid onset and longer duration of sensory block compared to MgSO4 . No significant adverse effects to the parturients or newborns.

RESUMEN

BACKGROUND AND AIM: Diabetic retinopathy is a serious and common complication of diabetes that causes irreversible blindness. The aim of the present study was to assess the knowledge, attitudes, and practice regarding diabetic retinopathy among patients attending a diabetic clinic and identify the effect of an educational program about diabetic retinopathy. PATIENTS AND METHODS: Two hundred diabetic patients were recruited from the outpatient's diabetic clinic, Assiut University hospitals, Egypt. Quasi-experimental (pretest-posttest) research design was applied using a structured interview questionnaire; including socio-demographic data, assessment of the patients' knowledge, attitude, and practices toward diabetic retinopathy. RESULTS: The mean score of knowledge and attitude showed significant improvement (5.3 and 15.1, respectively in pretest vs 16.7 and 16.8, respectively in posttest) among the diabetic patients (p<0.001). From multivariate linear regression model; the predictors for knowledge score were educational level, family history of diabetes and diabetic retinopathy and hypertension. Likewise, attitude score predictors were age, residence, and smoking. Predictors for practice score were hypertension, blood sugar level, and weight. CONCLUSION: There was a statistically significant relationship between educational level and mean knowledge score. The diabetic education program significantly helped to improve awareness of patients in relation to diabetic retinopathy.
