Introduction It has been estimated that between 15% and 18% of patients who start antiretroviral therapy (ART) do not achieve a successful immune recovery despite complete virological suppression. In the literature this phenomenom is known as poor immune recovery or immunovirological discordance (IVD). Zinc has an immunomodulatory role associated with T lymphocytes and its supplementation could enhance immune recovery. Objective To determine if zinc supplementation on IVD patients prevents immune failure after 12 months of supplementation. Secondary objectives were to determine serum zinc levels in HIV patients with and without IVD and the frequency of hypozincemia in discordant patients. Method We reviewed the historical record of patients under care at Arriarán Foundation. Following inclusion criteria were defined: 1) age ≥ 18 years, 2) standard ART (three effective drugs) for at least 18 months, 3) virologically suppressed for 12 months, 3) persistence of CD4 count ≤200 cells/mm3 and/or increase ≤ 80 cells/mm3 after one year of viral undetectability. A control group was assigned paired 1:1 by sex, age (± 2 years) that did achieved an increase of CD4> 350 cells/ mm3. In both groups plasma zinc levels were determined. In a later phase, patients with IVD were randomized to receive zinc (15 mg daily) versus placebo. Patients were followed for 12 months with CD4 count, viral load and zinc levels determinations every 4–6 months. Results A total of 80 patients, 40 patients with IVD criteria and 40 controls were included. 92.5% were men, and age average was 47.5 years. The median baseline CD4 was 189 cells/mm3 (71–258) in the cases vs. 552.5 cells/ mm3 (317–400) in the control group with a median increase at the end of the study of 39 cell/mm3 and 19 cell/mm3 respectively. There was no difference in baseline plasma zinc levels between both groups (81.7 + 18.1 in cases versus 86.2 + 11.0 in controls). In the 40 patients with IVD, the median absolute increase in CD4 after annual zinc supplementation was 31.5 cells/mm3 in the treated group versus 50 cells/mm3 in the placebo group, this difference being statistically not significant (p = 0.382). Conclusions Patients with IVD have plasma zinc levels similar to those who achieve adequate immune recovery. Zinc supplementation in IVD patients showed a statistically non-significant difference in in CD4 levels between cases and controls. The results warrant a comparative study with a larger number of patients.

A laboratory based 2 × 2 factorial experiment was conducted to investigate the effects of dietary phosphorus and zinc levels on hematocrit value, plasma alkaline phosphatase activity and plasma mineral contents of rainbow trout fingerling for 21 weeks. Two levels of phosphorus (19 and 30 mg/g) and two levels of zinc (55 and 100 µg/g) in the dry diets were tested. Duplicate tanks of 30 rainbow trout (average weight 1.56 ± 0.24g) per 60L glass tank were fed experimental diets three times a day to satiation level in 15 to 24oC water temperature. Zinc supplementation in the practical diets significantly increased the hematocrit value, plasma alkaline phosphatase activity and plasma zinc contents in rainbow trout fingerling. On the other hand, addition of phosphorus did not show any significant difference among the treatments. The result of the present study demonstrated that additional zinc significantly (P<0.05) influenced the hematocrit value, plasma alkaline phosphatase activity and plasma zinc contents in rainbow trout. Hence, it can be concluded that zinc supplementation is necessary in fingerling rainbow trout feed. Further studies in this area with different size and age of rainbow trout are needed broadly.DOI: http://dx.doi.org/10.3329/pa.v20i1-2.16870 Progress. Agric. 20(1 & 2): 183 – 192, 2009

INTRODUCTION We observed that a number of patients presenting to our clinic with diverticular fistulation were taking nicorandil for angna. Recognised side effects of nicorandil include gastrointestinal and genital ulceration. The aim of our study was to determine whether nicorandil is an aetiological agent in diverticular fistulation. PATIENTS AND METHODS We conducted a case-control study of patients with diverticular disease related enteric fistulae. Two patient groups were identified: a study group of patients with diverticular fistulae, and a control group with uncomplicated diverticular disease. The proportion of patients who had ever used nicorandil was compared between the two groups. RESULTS A total of 153 case notes were analysed, 69 patients with fistulae and 84 control patients with uncomplicated diverticular disease. Female to male ratio in both groups was 2:1. The mean age was 71 years in the fistula group and 69 years in the control diverticular disease group (P = ns). Of those with colonic fistulae, 16% were taking nicorandil compared with 2% of the control group (odds ratio 7.8; 95% confidence interval 1.5–39.1; P = 0.008). There was no significant difference in rates of ischaemic heart disease between fistula and control groups. CONCLUSIONS Nicorandil is associated with fistula formation in diverticular disease.

Background: Dyslipidemia is a metabolic disorder that results from imbalanced and overfeeding as well as sedentary life. Elevated blood lipid levels can affect cochlear blood flow and fluidity, leading to decreased hearing and tinnitus. We aimed to determine whether there is a relationship between tinnitus and dyslipidemia by investigating the blood lipoprotein values of patients with tinnitus.Methods: The lipid profiles of the patients with idiopathic tinnitus who were selected among the patients who applied to Istanbul Haydarpaşa Numune Training and Research Hospital with the complaint of tinnitus between January 2019 and May 2020 were examined. The test results and age and gender distributions were compared with control groups without tinnitus complaints and statistical evaluation was performed.Results: Hypercholesterolemia in 42% of 6472 patients with idiopathic tinnitus, 18% low HDL, 50% high LDL, Hyperlipidemia was detected in 21%. 1942 (30%) of these patients were male; 4530 (70%) are women. The number of patients in the control group without tinnitus was 6470. Hypercholesterolemia in 49% of this group; 21% low HDL, 42% high LDL, 16% hyperlipidemia was detected. In this control group, 1950 (30%) of the patients were male and 4520 (70%) were female. Cholesterol of male and female patients with tinnutus. When the cholesterol, LDL and triglyceride values of HDL and LDL values and female and male patients in the control group were examined, a statistically significant difference was found (p <0.005). No statistically significant difference was found between HDL values of female and male patients with tinnutus and HDL values of female and male patients in the control group (P> 0.05).Conclusions: There is a statistically relationship between tinnitus and dyslipidemia. The presence of dyslipidemia is vital due to atherosclerosis caused by dyslipidemia, especially coronary artery involvement. Therefore, dyslipidemia should be treated as it causes many diseases.

Abstract Purpose: In our study, we aimed to determine the frequency of thyroid nodules in patients with acromegaly according to the American College of Radiology (ACR) Thyroid Imaging, Reporting and Data System (TI-RADS) classification and its relationship with acromegaly disease activity. Methods: A total of 56 patients with acromegaly and age, sex, and body mass index matched with 56 healthy control subjects were included in our study. Thyroid-stimulating hormone, free thyroxine, and anti-thyroperoxidase antibody levels of patients and control subjects were measured. In addition, patients and healthy controls were evaluated by ultrasonography to determine thyroid structure, thyroid volume, and thyroid nodules and to make ACR TI-RADS classification. Results: Thyroid nodules were present in 31 (55.4%) of 56 patients in the acromegaly group and 20 (35.7%) of 56 subjects in the control group, and the frequency of thyroid nodules was significantly higher in the acromegaly group (p=0.038). The mean number of nodules in the acromegaly group and control group was 1.27±1.43 and 0.48±0.73, respectively, and the mean number of nodules was significantly higher in the acromegaly group (p=0.003). The number of patients with TI-RADS 1, TI-RADS 2, and TI-RADS 4 nodules in the acromegaly group was higher than the control group (p=0.026, p=0.049, p=0.007, respectively). No difference was found in terms of cytological findings between those who have undergone FNAB in the acromegaly group and control group. Conclusion: In our study, we found that the frequency of thyroid nodules, the number of thyroid nodules, and the number of TI-RADS 1, TI-RADS 2, and TI-RADS 4 nodules increased in patients with acromegaly. There was no significant difference between acromegaly disease activity and thyroid nodule frequency, number of thyroid nodules, and TI-RADS classifications.

Background and objectives: Anticoagulants are thought to increase the risks of traumatic intracranial injury and poor clinical outcomes after blunt head trauma. The safety of using direct oral anticoagulants (DOACs) compared to vitamin K antagonists (VKAs) after intracranial hemorrhage (ICH) is unclear. This study aims to compare the incidence of post-traumatic ICH following mild head injury (MHI) and to assess the need for surgery, mortality rates, emergency department (ED) revisit rates, and the volume of ICH. Materials and Methods: This is a retrospective, single-center observational study on all patients admitted to our emergency department for mild head trauma from 1 January 2016, to 31 December 2018. We enrolled 234 anticoagulated patients, of which 156 were on VKAs and 78 on DOACs. Patients underwent computed tomography (CT) scans on arrival (T0) and after 24 h (T24). The control group consisted of patients not taking anticoagulants, had no clotting disorders, and who reported an MHI in the same period. About 54% in the control group had CTs performed. Results: The anticoagulated groups were comparable in baseline parameters. Patients on VKA developed ICH more frequently than patients on DOACs and the control group at 17%, 5.13%, and 7.5%, respectively. No significant difference between the two groups was noted in terms of surgery, intrahospital mortality rates, ED revisit rates, and the volume of ICH. Conclusions: Patients with mild head trauma on DOAC therapy had a similar prevalence of ICH to that of the control group. Meanwhile, patients on VKA therapy had about twice the ICH prevalence than that on the control group or patients on DOAC, which remained after correcting for age. No significant difference in the need for surgery was determined; however, this result must take into account the very small number of patients needing surgery.

Abstract Background and Aims There are six IL-17-family ligands [IL-17A, IL-17B, IL-17C, IL-17D, IL-17E (IL-25) and IL-17F]. Interleukin-17A (IL-17A) also commonly called IL-17, is produced by the T helper17 (Th17) subset of CD4+ T cells.Interleukin-17 and other Th17 cytokines are linked to the pathogenesis of diverse autoimmune and inflammatory diseases. IL-17A is detected in synovial fluids and synovium from RA patients and induces proinflammatory cytokine production from synoviocytes, also expression of IL-17A was higher in SLE patients and its level positively correlated with the severity of lupus nephritis, because of its contribution to increasing anti-double-stranded DNA (dsDNA) antibody production in SLE. The aim of the present study is to determine the IL-17A gene polymorphism (rs2275913 G&gt;A) frequency in patients with SLE and lupus nephritis, and to determine the association of this polymorphism with the disease activity. Method This cross-sectional, observational, case control study was carried out on 50 females patients, with their age ranged from 15 to 50 years (mean 25.67±9.29 years) with SLE attending Mansoura University Hospital .A control group of 50 healthy females of matched age were also included. The patient group was subdivided into patients with and those without lupus Nephritis (35 and 15 patients, respectively). Lupus nephritis was confirmed by renal biopsy. All patients were subjected to a thorough clinical evaluation and routine laboratory tests. SLEDAI score was calculated for all patients to determine the degree of lupus activity. DNA extraction was performed for all patients as well as controls, One SNPs of IL-17A (rs2275913G&gt;A) was genotyped utilizing PCR- RFLP technique. Results The frequency of rs2275913 A allele was significantly higher in SLE patients than the control group (34.0% vs. 21.0%, respectively; p=0.04, OR =1.9, 95%CI =1.03-3.65). While G allele was significantly higher in control group, (P=0.04)). Moreover, AA genotype was significantly higher in the SLE patients than in the control group (8.0% vs. 0.0%, respectively; p=0.036) and associated with higher SLEDAI, ANA, and anti-dsDNA antibodies titer, (P=0.03, P=.039, P=0.047 respectively).on the other hand there was no significant difference in GG and GA genotypes in the SLE patients versus the control group. The frequency of both genotype GA and AA was higher in the SLE patients than the controls (60% vs. 42%, respectivley; OR=2.07, CI-95%=0.9-5.59); although the difference was not statistically significant (P= 0.07).Although A allele was numerically higher in lupus nephritis group versus non nephritis group(37.0% vs 27.0%, respectively), the Analysis of the frequency of IL-17A rs2275913 alleles and genotypes showed no statistical differences between the two groups. Moreover there was no statistical significance between different genotypes in cases of nephritis regard lupus nephritis class (P=0.9) and no statistical significance between different genotypes (GG-GA-AA) regarding activity indices (AI) or chronicity indices (CI) in lupus nephritis group (P=0.18, P=0.56 respectively). Conclusion We suggest that there was a significant association between IL-17A rs2275913 G&gt;A polymorphism and SLE, as A allele and AA genotype were increased in SLE patients, lupus nephritis especially those with high activity

A laboratory based 2 × 2 factorial experiment was conducted to investigate the influence of dietary phosphorus and zinc levels on whole body mineral, liver mineral, and liver vitamin-C contents of fingerling rainbow trout for 21 weeks. Two levels of phosphorus (19 and 30 mg g-1) and two levels of zinc (55 and 100 μ g g-1) in the dry diets were tested. Duplicate tanks of 30 rainbow trout (average weight 1.56 ± 0.24 g) per 60L glass tank were fed experimental diets three times a day to satiation level in 15 to 24oC water temperature. The result of the present study demonstrated that dietary zinc supplementation significantly influenced the whole body zinc and liver copper contents in fingerling rainbow trout where as additional phosphorus did not show any significant difference. Zinc supplementation significantly influenced the liver vitamin-C contents of the fish. Hence it is clear that zinc supplementation is necessary in fingerling rainbow trout feed. Further studies in this area are needed broadly.

Background. The aim of this study was to assess the association between herbal medication and OHSS.Methods. This retrospective cohort study was conducted with 101 polycystic ovary syndrome patients. 66 patients took conventional pharmacological medications and 35 took herbal medications. Data were analyzed by statistical test including Fisher’s Exact and binominal logistic regression.P<0.05was considered significant.Results. Of the 101 females, 53 were married and 48 were single. There was no significant association between the groups in marriage. No significant association was found in mean age between the two groups (23.9 ± 5.8 years in the control group versus 26.3 ± 6.7 years in the case group). There was a significant difference between the two groups .After adding the dependent (OHSS prevalence) and independent (marriage and group) variables into the model, the Hosmer-Lemeshow test showed suitability. Variances analyzed with this model ranged between 29.4% and 40.7%.Conclusion. The indiscriminate use of herbs is correlated with OHSS. Because patients increasingly consume herbs, they should be aware of potential side effects. However, appropriate dosages of herbs could be obtained for use instead of conventional treatments, which often have side effects.

Background: In sports such as roller skates, endurance can lead to increased inflammation and muscle cell damage, free radical formation, and zinc excretion from sweat and urine that affect the increased redistribution of zinc from blood to tissue. This mechanism causes a decrease in blood zinc levels, erythrocyte numbers and hemoglobin concentrations, increased leukocyte counts and the body’s oxidative stress parameters that have an impact on the athlete’s performance decline. Zinc supplementation may be given to maintain the athlete’s hematologic parameters during endurance exercise.Objectives: To examine the effect of zinc supplementation on serum zinc level, hemoglobin concentration, erythrocyte and leukocyte counts, and blood MDA level of skate athletes after endurance exercise.Method: This study was an experimental clinical trial using pre and post-test designs on 8 athletes incorporated in the Pre-PON DIY Wheels Team. The study was conducted in two periods, one week of endurance exercise without zinc supplementation and one week of endurance exercise with 30 mg/d of zinc supplementation. Blood sampling was performed on the seventh day of each period, before and after endurance training.Results: There was a decrease in erythrocytes and hemoglobin concentration, and a significant increase in leukocyte count after endurance training in both periods (p<0.05), but no significant difference in serum zinc levels and MDA levels after endurance training in both periods (p>0.05). Although there were no significant differences in all athlete hematologic parameters between two treatments (p>0.05), there was an improvement in serum zinc levels, hemoglobin concentrations, erythrocyte, and leukocyte counts.Conclusion: Zinc supplementation 30 mg/day for one week did not have a significant effect on the athlete’s hematology parameters after endurance exercise.
