Anxiety and work overload perception levels of primary healthcare professionals during the COVID-19 pandemic.

BACKGROUND: The coronavirus disease (COVID-19) has greatly affected healthcare workers at the physical and psychosocial level. In this process, primary healthcare workers have taken the most active role by taking part in the filiation groups. OBJECTIVE: This study aimed to determine the anxiety and workload perception level of primary healthcare workers during the COVID-19 pandemic. METHODS: This was a cross-sectional study. An online survey was conducted among 197 healthcare workers. Personal Information Form, the Coronavirus Anxiety Scale and Work Overload Scale were used as data collection tools in the research. Independent Two-Sample T-Test, One-Way Analysis of Variance, Mann-Whitney U test and Kruskal Wallis test were used to evaluate the data. Moreover, the relationships between the scales were evaluated with Pearson correlation analysis and simple regression analysis. RESULTS: The median total score of the Coronavirus Anxiety Scale of healthcare workers was 3.0, and the mean score of the Work Overload Scale was 37.89±7.47. It was found that there was a correlation between the Coronavirus Anxiety and the Work Overload Scales and 21.0% of the variance changes in the Work Overload Scale were affected by coronavirus anxiety. CONCLUSION: It was determined that the level of coronavirus anxiety affects the perception of workload. Therefore, it is recommended that work plans should be made considering this situation.

Pregnancy and its outcomes in hemodialysis patients in Turkey.

BACKGROUND/AIM: This study aimed to investigate pregnancy frequency and evaluate the factors affecting live births in hemodialysis (HD) patients. MATERIALS AND METHODS: Female HD patients whose pregnancy was retrospectively reported between January 1, 2014, and December 31, 2019. The duration of HD, primary disease, whether the pregnancy resulted in abortion, stillbirth, or live birth, whether the HD duration was prolonged after diagnosing the pregnancy and whether it accompanied preeclampsia were recorded. RESULTS: In this study, we reached 9038 HD female patients? data in the study. A total of 235 pregnancies were detected in 145 patients. The mean age was 35.42 (35 ± 7.4) years. The mean age at first gestation was 30.8 ± 6.5 years. The average birth week was 32 (28 - 36) weeks. 53.8% (no = 78) of the patients had live birth, 51.7% (no = 70) had at least one abortion in the first 20 weeks, and 13.1% (no = 19) had at least one stillbirth after 20 weeks. The rate of patients' increased numbers of dialysis sessions during pregnancy was 71.7%. The abortion rate was 22.4% in those with increased HD sessions, whereas 79.3% in those not increased HD sessions (p < 0.001). Live birth frequency was 67.2% in the increased HD sessions group and 3.4% in those who did not differ in HD sessions (p < 0.001). CONCLUSION: For the first time, we reported pregnancy outcomes in HD female patients, covering all regions of Turkey. It has been observed that; increasing the number of HD sessions in dialysis patients will decrease fetal and maternal complications and increase live birth rates.

The effects of Mucuna pruriens on the renal oxidative stress and transcription factors in high-fructose-fed rats.

In the present study, we evaluated the effects of M. pruriens administration on metabolic parameters, oxidative stress and kidney nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) and nuclear factor (erythroid-derived 2)-like 2 (Nrf2) signaling pathways in high-fructose fed rats. Male rats (n = 28) were divided into 4 groups as control, M. pruriens, fructose, and M. pruriens plus fructose. All rats were fed a standard diet supplemented or no supplemented with M. pruriens (200 mg/kg/d by gavage). Fructose was given in drinking water for 8 weeks. High fructose consumption led to an increase in the serum level of glucose, triglyceride, urea and renal malondialdehyde (MDA) levels. Although M. pruriens treatment reduced triglyceride and MDA levels, it did not affect other parameters. M. pruriens supplementation significantly decreased the expression of NF-Ò¡B and decreased expression of Nrf2 and HO-1 proteins in the kidney. This study showed that the adverse effects of high fructose were alleviated by M. pruriens supplementation via modulation of the expression of kidney nuclear transcription factors in rats fed high fructose diet.

Neutrophil gelatinase-associated lipocalin reflects the severity of anemia without iron deficiency and secondary hyperparathyroidism in hemodialysis patients.

OBJECTIVE: Secondary hyperparathyroidism (SHPT) and anemia are the primary and most common complications in patients receiving hemodialysis (HD). Neutrophil gelatinase-associated lipocalin (NGAL) is a new marker to assess iron deficiency and manage iron therapy for HD patients. The aim of this study was to determine any association between serum NGAL level and anemia without iron deficiency in patients with SHPT on chronic HD. METHODS: Total of 61 SHPT patients on chronic HD were enrolled in the study and divided into 3 groups: mild SHPT group (n=17), moderate SHPT group (n=21), and severe SHPT group (n=23). Hemogram, biochemical assays, and level of ferritin, high sensitivity C-reactive protein (hs-CRP), and NGAL were evaluated in all groups. RESULTS: Serum NGAL level was significantly higher and hemoglobin (Hb) level was significantly lower in severe SHPT patients compared with both mild and moderate SHPT patients. Furthermore, in severe SHPT group, serum NGAL level was significantly positively correlated with serum parathyroid hormone (r=0.79; p=0.00) and hs-CRP (r=0.52; p=0.01) level and negatively correlated with serum Hb (r=-0.56; p=0.00) level. CONCLUSION: SHPT was important factor affecting anemia in HD patients. Even when iron deficiency anemia is excluded in patients with SHPT, there was significant negative correlation between serum NGAL and Hb.

Evaluation of nutritional status using anthropometric measurements and MQSGA in geriatric hemodialysis patients.

OBJECTIVE: Malnutrition is common among hemodialysis patients and is associated with higher rates of morbidity and mortality. The aim of this study was to evaluate nutritional status of geriatric hemodialysis patients. METHODS: Total of 163 hemodialysis patients were initially screened, and 55 patients (28 males, 27 females; mean age: 72.9±8.4 years) met the criteria for inclusion. Patients were divided into 3 groups according to modified quantitative subjective global assessment (MQSGA) scores: Group I (n=22) normal nutrition, Group II (n=20) mild-to-moderate malnutrition, and Group III (n=13) severe malnutrition. RESULTS: When we assessed the correlation between MQSGA nutrition score and data of malnourished patients (n=33), positive significant correlation was found between age, C-reactive protein level, and malnutrition-inflammation score. Negative significant correlation was found between body mass index, bicep skinfold, tricep skinfold, mid-arm circumference, mid-arm muscle circumference, and phosphate and albumin levels. CONCLUSION: Malnutrition is very common and increasing with aging in geriatric hemodialysis patients. MQSGA score and anthropometric measurements can be used to assess nutritional status in geriatric hemodialysis patients.

Relationships between plasma pentraxin 3 levels and inflammation markers patients with tunneled permanent catheter in hemodialysis.

PURPOSE: Vascular access (VA) devices may contribute to chronic inflammation in hemodialysis (HD). Pentraxin 3 (PTX3) is a recently discovered acute phase protein that responds more rapidly than other inflammatory markers. This study compared PTX3 and other markers between HD patients and healthy controls. METHODS: The study population included 30 patients with tunneled permanent catheter (TPC), 30 patients with arteriovenous fistula (AVF) and 30 healthy controls. Hemogram, biochemical assays, ferritin, high sensitive C-reactive protein (hs-CRP), tumor necrosis factor-α (TNF-α) and PTX3 were evaluated in all groups. RESULTS: PTX levels were highest in HD patients with TPC, intermediated in HD patients with AVF and lowest in healthy controls (5.2 + 2.4 vs. 3.1 + 1.3 vs. 1.8 + 0.7, p<0.001 for all comparisons). PTX3 levels correlated strongly to hs-CRP (r = 0.857) and moderately to TNF-α, NLR, ferritin and total neutrophil count. PTX3 and albumin levels had a negative correlation. PTX3 levels were higher in patients with 8 months of TPC than those with 7 months or less. CONCLUSIONS: PTX3 levels are significantly elevated in all patients on HD, but presence and extended duration of TPC are associated with incrementally higher levels of PTX3 and other inflammatory markers. PTX3 and NLR may be useful in assessing chronic inflammatory states in HD.

The renoprotective effect of curcumin in cisplatin-induced nephrotoxicity.

The polyphenol curcumin has several pharmacological effects, including antioxidant, anti-inflammatory and anti-cancer features. In this study, we evaluated the effects of curcumin in cisplatin-induced nephrotoxicity in rats. Male Wistar rats were divided into four groups: (1) control; (2) cisplatin (7 mg/kg body weight, intraperitoneal as a single dose); (3) curcumin (100 mg/kg via gavage, for 10 days); and (4) cisplatin and curcumin. The cisplatin-treated rats exhibited kidney injury manifested by increased serum urea and creatinine (p<0.05). The kidney tissue from the cisplatin treated rats also exhibited a significant increase in the malondialdehyde (MDA) levels (p<0.05). The treatment with curcumin prevented a rise in the serum urea, creatinine and MDA levels when compared to the control group kidneys (p<0.05). The analysis the nicotinamide phosphoribosyltransferase (NAMPT) and sirtuin (SIRT) proteins (SIRT1, SIRT3 and SIRT4), which play important roles in the resistance to stress and the modulation of the threshold of cell death, showed similar trends (p<0.05). In the cisplatin-only treated rats, the induced renal injury decreased the levels of the NAMPT and SIRT proteins. Conversely, the curcumin increased the levels of the NAMPT and SIRT proteins in the cisplatin-treated rats (p<0.05). These data suggest that curcumin can potentially be used to reduce chemotherapy-induced nephrotoxicity, thereby enhancing the therapeutic window of cisplatin.

Can serum NGAL levels be used as an inflammation marker on hemodialysis patients with permanent catheter?

BACKGROUND: Neutrophil gelatinase-associated lipocalin (NGAL) is a member of lipocalin family and released from many tissues and cells. We aimed to investigate the relationship among serum NGAL levels, the inflammation markers (IL-6, hs-CRP, TNF-α) and different vascular access types used in dialysis patients. METHODS: The study population included 90 patients and 30 healthy age-matched controls. The patients were divided into three groups (I, II, III) and group IV included the controls. In group I and II, the patients were with central venous permanent catheter and arterio-venous fistula, respectively. Group III included 30 patients with chronic renal failure. Hemogram, biochemical assays, ferritin, IL-6, hs-CRP, TNF-α, and NGAL were evaluated in all groups. RESULTS: Serum NGAL levels were markedly higher in group I than in group II (7645.80 ± 924.61 vs. 4131.20 ± 609.87 pg/mL; p < 0.05). Positive correlation was detected between NGAL levels and duration of catheter (r: 0.903, p: 0.000), hs-CRP (r: 0.796, p: 0.000), IL-6 (r: 0.687, p: 0.000), TNF-α (r: 0.568, p: 0.000) levels and ferritin (r: 0.318, p: 0.001), whereas NGAL levels were negatively correlated with serum albumin levels (r: -0.494, p: 0.000). In multiple regression analysis, duration of catheter hs-CRP and TNF-α were predictors of NGAL in hemodialysis patients. CONCLUSION: Inflammation was observed in hemodialysis patients and increases with catheter. Our findings show that a strong relationship among serum NGAL levels, duration of catheter, hs-CRP and TNF-α. NGAL may be used as a new inflammation marker in hemodialysis patients.

Hypovolemia-related gastric tissue damage in the setting of upper gastrointestinal bleeding.

BACKGROUND/AIMS: Much is known about the gastric tissue damage that is associated with hypovolemic stress, but gastrointestinal bleeding due to gastric injury and further gastric injury due to hypovolemia have not been evaluated in previous research. The aim of this study was to assess oxidative gastric tissue damage specifically linked to hypovolemia in patients with upper gastrointestinal bleeding. METHODS: The study included 30 patients who presented with acute upper gastrointestinal bleeding and 30 controls. Each patient's history and laboratory findings were recorded, and multiple biopsies of the gastric antrum were obtained at diagnostic endoscopy on admission (day 1) and five days later. A set of antral biopsies was also collected from each control subject. Each tissue specimen was analyzed for levels of glutathione peroxidase, superoxide dismutase and catalase activity, and level of malondialdehyde. RESULTS: First day glutathione peroxidase, superoxide dismutase and catalase levels were significantly lower and malondialdehyde levels were higher than on the 5th day, and 1st day and 5th day levels were significantly different from controls (p<0.05). A moderate level of correlation was detected between catalase and hemoglobin (r:-0.59) and hematocrit (r:-0.61) and between malondialdehyde and systolic blood pressure (p:0.58), hematocrit (r:0.45) and hemoglobin (r:0.49). CONCLUSIONS: In this study, gastric tissue oxidative markers showed antral oxidative changes to be significantly correlated with patients' hemodynamics. Oxidative stress may not be a clinical condition but it obviously shows gastric tissue damage and may explain many of the patients' additional diagnosis of gastric erosions. Interestingly, the oxidative change does not completely recover even on the 5th day.

The relationship between severity of liver cirrhosis and pulmonary function tests.

Pulmonary complications, mainly hepatopulmonary syndrome (HPS), are frequently observed in liver cirrhosis. In this study, the aim was to investigate the frequency of hypoxemia and impairment of pulmonary function tests (PFT) in patients with liver cirrhosis and to examine the relationships of these impairments with liver failure. A total of 39 patients with cirrhosis, 24 males and 15 females, were included in our study. The mean age of the patients was 47.5 +/- 17.2 years. Arterial blood gases, PFT, and carbon monoxide diffusion tests (DLCO) were performed in all patients. Out of 39 cirrhotic patients, 21 (53.8%) had ascites, whereas 18 (46.2%) did not. Seven patients were in the Child-Pugh A group, 21 in the Child-Pugh B group, and 11 patients were in the Child-Pugh C group. Hypoxia was found in 33.3% of the patients. Although the PaO2 and SaO2 values of patients with ascites were lower compared to those without ascites (P < 0.05), no statistically significant difference was determined in the comparison of hypoxia between the groups (P > 0.05). Among the PFT parameters, FEV1/FVC and FEF25-75% values were found to be lower in patients with ascites than those without (P < 0.05). No differences were established between these two groups of patients in terms of DLCO (P > 0.05). While no differences were found in comparison of the DLCO values in between the groups (P > 0.05), there was a statistically significant difference in the ratio of DLCO to the alveolar ventilation (DLCO/VA) in between the groups (P < 0.05). On the other hand, a negative correlation was found between the DLCO/VA and Child points when the relationship between the Child-Pugh score and PFT parameters were investigated (r = -0.371, P < 0.05). Consequently, a relationship was established between the severity of liver failure and diffusion tests showing pulmonary complications invasively. We believe diffusions tests should be performed in addition to the PFT in order to determine pulmonary involvements particularly in patients who are candidates for liver transplantation.
