Calculated Globulin Is Clinically Useful as a Screening Test for Antibody Deficiency in Turkish Adult Patients.

INTRODUCTION: Heterogeneous clinical features of antibody deficiency (AD) may cause diagnostic delays. Calculated globulin (CG) (total protein minus albumin) has been proposed as a screening test to prevent morbidity due to diagnostic delays in AD. Our aim was to validate CG as a screening test for AD in Turkish adult patients by comparing its role with gamma globulin analysis in protein electrophoresis. METHODS: Fifty serum samples were randomly collected for each level of CG from 15 to 25 g/L and tested for serum IgG, IgA, IgM levels and protein electrophoresis. Cut-off values predicting low IgG levels were calculated for electrophoretically determined gamma globulin and CG. Additionally, the data of 47 patients followed up in our clinic with a diagnosis of primary antibody deficiency (PAD) were retrospectively analyzed. RESULTS: A total of 550 adult patients were included in the study. The CG value predicting patients with IgG <6 g/L as a screening test was determined as <20 g/L with 83.8% sensitivity and 74.9% specificity. The gamma globulin value which predicted patients with the same IgG value of 89.0% sensitivity and 89.4% specificity was determined as <7 g/L. In the retrospective analysis, 37 of 47 patients (78.7%) with PAD had a CG value of <20 g/L at the time of the diagnosis and all 13 patients (100%) whose gamma globulin values were measured at the time of the diagnosis had a gamma globulin value of <7 g/L. CONCLUSION: The determined CG cut-off value of <20 g/L can be used as a screening test in Turkish adult patients.

Estimates and Forecasts on the Burden of Prediabetes and Diabetes in Adult and Elderly Population in Turkiye.

AIMS: Diabetes mellitus is a chronic disease that limits the quality and duration of life. We aimed to estimate the impact of demographic change on the burden of prediabetes and diabetes between 2010 and 2021, and the projections to 2030 and 2045 in Turkiye. MATERIALS AND METHODS: Prediabetes and diabetes estimates were calculated by direct standardization method using age- and sex-specific prevalence data from the previous 'Turkish Epidemiology Survey of Diabetes, Hypertension, Obesity and Endocrine Disease' (TURDEP-II) as reference. The 2010-2021 population demographics were obtained from TurkStat. Comparative age-adjusted diabetes prevalence was estimated using the standard population models of world and Europe. RESULTS: Estimates depicted that the population (20-84 years) of any degree of glucose intolerance in Turkiye increased by over 5.7 million (diabetes: 2.4 million and prediabetes: 3.3 million) from 2010 to 2021. While the increase in prediabetes and diabetes prevalence was 24.3% and 35.2% in overall population, corresponding increase were 46.5% and 51.3% in the elderly. Estimated prevalence of prediabetes and diabetes in 2021 was significantly higher in women than in men (prediabetes: 32.6% vs. 25.2%; diabetes: 17.1% vs. 14.2%). The comparative age-adjusted diabetes prevalence to the European population model was higher than that of the world population model (19.4% vs. 15.0%). According to the projections the prevalence of diabetes will reach 17.5% in 2030 and 19.2% in 2045. CONCLUSION: Assuming age- and sex-specific diabetes prevalence of TURDEP-II survey remained constant, this study revealed that the number of people with diabetes in the general population (particularly in the elderly) in the last 11 years in Turkiye has increased in parallel with the population growth and aging; it will continue to grow over the coming decades. This means the burden of diabetes on the social, economic and health services will remain to increase. The fact suggests that there is an urgent need for re-organization of care as well as to develop and implement a country-specific prevention program to reduce this burden.

Telemedicine as a Motivational Tool to Optimize Metabolic Control in Patients with Diabetes in Turkey: A Prospective, Randomized, Controlled TeleDiab Trial.

Introduction: Telemedicine is a follow-up system that can improve the quality of management and cost-effectiveness of rapidly increasing diabetes patients. Methods: Two hundred adult patients with diabetes were enrolled in this prospective, randomized study. Consecutive patients were divided equally into two groups. Both groups received routine care visits quarterly. TeleDiab group also sent self-monitoring of blood glucose data and received short message service over the transmission system for 12 months. After the study was completed, all patients continued their routine care visits, and their data were evaluated for another 12 months. Six years after the initial study, patients were contacted by phone during the Covid-19 lockdown, and their status was assessed. Results: At the end of the study, glycemic control, kidney function, and lipid parameters of the TeleDiab group were statistically significantly better than the Usual Care group. There was no significant change in the weights of the patients. It was observed that this state of wellbeing continued both at the end of the second year and during the Covid-19 lockdown. Individuals with type 2 diabetes were found to benefit more from telemedicine. Discussion: It has been beneficial to guide patients with applications such as TeleDiab in diseases such as diabetes that require lifelong follow-up. On the other hand, the importance of telemedicine programs in the management of chronic diseases in the current pandemic conditions has come to the fore even more. Telemedicine is an effective motivational tool to ensure optimal control not only of glycemic but also of kidney and lipid parameters.

Serum C-Reactive Protein and Sex Hormone Levels in the Early Hyperacute Phase of Stroke.

BACKGROUND: To see the relationship of early admission parameters with the type of stroke and/or with the 30-days mortality from this disease. METHODS: Stroke patients at their early hyperacute phase (n = 180) were enrolled in this study (156 ischemic strokes and 24 hemorrhagic strokes). Blood levels of C-reactive protein (CRP), testosterone, and estradiol were determined at admission, before any specific intervention. Patients' clinical data, including the above-mentioned laboratory parameters, were compared between the above two stroke types (in total and between sexes). RESULTS: The mean age of the patients was 69.55 ± 12.03 years old (69.92 ± 11.94 years old in ischemic stroke and 67.12 ± 12.54 years old in hemorrhagic stroke). Serum estradiol levels of both males of ischemic stroke and females of hemorrhagic stroke patients were significantly higher than the females of the ischemic stroke. Serum CRP levels of both females and males of the hemorrhagic group were higher than their peers of the opposite group. Early admission serum CRP level ≥ 0.74 mg/dL in males helped predict hemorrhagic stroke while a serum estradiol level ≥ 14.07 ng/mL helped predict the same type of stroke in females. CONCLUSIONS: Our study results show that simple early laboratory measures (such as CRP and estradiol) may help in the early phase management of stroke. Further studies are needed to confirm our findings.

Paucigranulocytic asthma: Do sputum macrophages matter?

Background: Although paucigranulocytic asthma (PGA) is the most common phenotype of stable asthma, its features have not been adequately studied. In this study, we aimed to display the characteristics of PGA. Method: A total of 116 non-smoking adult patients with asthma (80% women; mean ± standard deviation age, 39 ± 12.9 years) admitted to three tertiary centers were included. Their demographic and clinical features, allergy status, biochemical results, scores of Asthma Control Test (ACT), spirometry, and exhaled nitric oxide (FeNO) measurements were obtained. Induced sputum cytometry was performed. Results: Four phenotypes, according to induced sputum cell counts, were detected: eosinophilic asthma (EA) (22.4%), mixed granulocytic asthma (MGA) (6.9%), neutrophilic (NA) (7.8%), and PGA (62.9%). In the sputum, macrophages were higher in the PGA group compared with the other groups (PGA versus NA and PGA versus MGA, p < 0.001; and PGA versus EA, p =0 .030). The atopy rate between phenotypes was the same. Although the forced expiratory volume in the first second of expiration (FEV1) was similar in four groups, the ratio of FEV1 to the forced vital capacity ratio was higher (p = 0.013) and FEV1 reversibility was lower in the patients with PGA than the corresponding values in other phenotypes (p = 0.015). Low reversibility was comparable both in patients with PGA who were inhaled corticosteroid (ICS) naive and in patients on ICS treatment. Although insignificant, the FeNO values and blood eosinophil counts were higher in the MGA and EA groups, whereas these were the lowest in the PGA group. The uncontrolled asthma ratio was low in PGA (16%), whereas it was 11% for NA, 25% for MG, and 23% in EA. Conclusion: Macrophages are predominant in sputum of patients with PGA. Besides a lower uncontrolled asthma ratio, lower FEV1 reversibility is a prominent characteristic of this phenotype.

Annual influenza vaccination effect on the susceptibility to COVID-19 infection.

OBJECTIVES: We aimed to study the effect of seasonal influenza (flu) vaccination on the susceptibility to coronavirus disease 2019 (COVID-19). METHODS: A total of 203 healthcare workers of a pandemic centre of Istanbul, Turkey, were included in this retrospective study. According to the presence or absence of flu vaccination, participants were divided into group 1 and group 2. A comparison of the rate of COVID-19 was done between these two groups. Also, the mean age and the sex ratio of females/males were evaluated and compared between these two groups. RESULTS: Group 1 participants (n = 65) were older than participants in group 2 (n = 138) (p < 0.05). Despite of this, interestingly, the COVID-19 infection rate was lower in the 1st group (in comparison to the 2nd group) (p < 0.05). CONCLUSION: Our study results showed that, even if low, the flu vaccination may have a protective effect on the susceptibility to COVID-19 infection. Using this beneficial adjuvant effect of the vaccine may help us in this unpredictable battle with the COVID-19 pandemic. Further studies are needed to confirm this assumption.

Comparison of intermittent and consecutive balneological outpatient treatment (hydrotherapy and peloidotherapy) in fibromyalgia syndrome: a randomized, single-blind, pilot study.

To compare the efficacy of intermittent and consecutive balneological outpatient treatment (hydrotherapy and peloidotherapy) in fibromyalgia syndrome (FMS). A parallel 1:1, single-blind, pilot study was performed. Patients were recruited from musculoskeletal disorders outpatient clinic. Eligible participants were patients aged 18-60, diagnosed as FMS according to ACR 2010 criteria. They were randomly assigned to either consecutive or intermittent treatment groups. Both groups received 20 min of full body immersion in a tap water pool at 38-39 °C and 30 min of mud pack application on the back region at 45 °C. Delivery of the treatment was five times weekly during 2 weeks in consecutive group and two times weekly during 5 weeks in intermittent group. The primary outcomes were pain intensity and the number of patients achieving a minimal clinically important difference (MCID) on Fibromyalgia Impact Questionnaire (FIQ) at the 1st month after the completion of the treatment. Statistical analyses were based on intention to treat method. The assessing physician was blinded. Pain intensity significantly decreased in all post-treatment evaluations of both groups (except after treatment in the intermittent group). There was no significant difference between the groups. MCID for FIQ was achieved in 6 (24%) patients in the consecutive group and 12 (48%) in the intermittent group at the 1st month. There was no statistical difference in the secondary judgment criteria. The consecutive and intermittent deliveries of balneological outpatient treatment (hydrotherapy and peloidotherapy) seem to have similar effects on the clinical status of patients with FMS.

The effects of noise levels on nurses in intensive care units.

BACKGROUND: Intensive care units (ICUs) are noisy environments, which may have negative psychological effects on nurses. AIMS AND OBJECTIVES: To investigate the effects of the noise level of ICUs on nurses' burnout, job satisfaction, anxiety, psychological symptoms and general psychopathology level. DESIGN: A descriptive and correlational study. METHODS: The study was conducted with 150 intensive care nurses. A Type 2250-L Brüel & Kjaer hand-held sound level meter was used for noise measurement. A Nurse Information Form, the Maslach Burnout Inventory, Minnesora Satisfaction Questionnaire, Self-Report Inventory and Symptom Checklist-90 Revised were used for data collection. RESULTS: The highest levels of noise (71 dB(A) and above) were measured in the neonatal, neurology and cardiovascular surgery ICUs. It was observed that noise level affected extrinsic satisfaction (F = 3·704; p = 0·027) and trait anxiety (F = 3·868; p = 0·023) of nurses. CONCLUSIONS: Noise levels in ICUs are well above the recommended levels, and this affects nurses' job satisfaction and anxiety levels. RELEVANCE TO CLINICAL PRACTICE: More studies on the effects of noise levels on the physical and mental states of nurses working in ICUs are needed. Increased quality of patient care can be achieved by providing healthy working conditions for nurses working in special units such as ICUs.

Combined effect of parathyroid hormone and strontium ranelate on bone healing in ovariectomized rats.

OBJECTIVE: Parathyroid hormone (PTH) enhances bone healing. Strontium ranelate (SR) is an antiresorptive agent that increases bone formation. Reports about combined effects of PTH and SR on local bone regeneration in osteoporotic subjects are limited. We aimed at investigating the efficacy of PTH and SR for promoting new bone formation in critical-sized defects of ovariectomized rats. MATERIALS AND METHODS: Parathyroid hormone- and/or SR-containing poloxamer implant tablets with/without chitosan microparticles were delivered locally to calvarial defects of 90 Wistar rats. Biopsies were analyzed histologically and histomorphometrically at 4 and 8 weeks of healing. RESULTS: Histomorphometry revealed that PTH alone promoted new bone formation at 4 weeks but the efficiency declined in 8 weeks. There was no positive effect of SR alone on bone formation at 4 or 8 weeks. Calvarial defects treated with PTH+SR combinations showed statistically significant greater new bone formation than either treatment alone at both time intervals. Tissue responses were modest and supported the good biocompatibility of the biomaterials used. CONCLUSION: Parathyroid hormone and SR combinations can be effective for calvarial bone regeneration of ovariectomized rats. PTH plus SR may have potential use as bone graft material in orthopedic and dental surgery to enhance bone healing and osseointegration.

High adherence to subcutaneous immunotherapy in a real-life study from a large tertiary medical center.

BACKGROUND: Studies on real-life adherence to subcutaneous allergen immunotherapy (SCIT) for respiratory allergy are scarce. The aim of this study was to evaluate adherence to SCIT. METHODS: The patients prescribed SCIT for allergic rhinitis and/or asthma in 2009-2011 were contacted in 2014 and asked whether they completed at least the 3 years of SCIT and/or whether they suspended the treatment for at least 2 months. The Total Symptom Score-6, visual analog scale (VAS), asthma control test (ACT), medication scores, quality of life (QoL) scores, and immunotherapy satisfaction scores with VAS obtained before the initiation of SCIT in the first year and at the end of SCIT were compared. RESULTS: A total of 204 patients (136 female [66.7%]; mean age, 38.83 ± 12.02 years) were included; 73% (149/204) were both compliant and persistent; 14% (29/204) were only persistent; and, overall, 87.3% (178/204) were considered adherent. Adherence was more frequent in female patients (95% CI, 62.3-76.3%; p = 0.018). Medication, symptom, ACT, and QoL scores in the first year and at the end of the treatment were significantly lower than the initial scores, and the immunotherapy satisfaction scores at the end of treatment were higher than the scores in the first year in the patients who were adherent (p < 0.001 for each score). CONCLUSION: The adherence rate to SCIT in our study was relatively high, in contrast to previous real-life data. Results of our study indicated that a close relationship between allergists and their patients during SCIT and the follow-up period in the same center improved the outcome of SCIT.

[Efficiency of nebulised magnesium sulphate in infective exacerbations of chronic obstructive pulmonary disease]. / Kronik obstrüktif akciger hastaligi enfektif alevlenmelerinde nebül magnezyum sülfatin etkinligi.

INTRODUCTION: Conflicting results has been achieved in a small number of clinical studies evaluating the efficiency of magnesium sulphate (MS) in COPD exacerbations. We aimed to investigate the efficiency of nebulised MS in COPD exacerbations. PATIENTS AND METHODS: Twenty patients who met the study criteria were randomized into two groups. All patients were treated with O2, antibiotics and oral corticosteroids. Additionally one group received ipratropium bromide (IB) 500 µg together with MS 151 mg/dose, while the other group received IB together with placebo. The patients were followed-up with forced expiratory volume in 1 second (FEV1) and visual analogue scale dyspnea scores for 48 hours. Peak expiratory flow rates (PEFRs) were measured before and 10, 30, 60 and 120 minutes after each nebule treatment. RESULT: The baseline characteristics of the patients in both groups were similar. The FEV1 values measured at 24 and 48 hours did not show significant changes compared to baseline in both groups. Dyspnea scores in both groups decreased significantly in the first day, and in only MS group in the second day. The % change in the dyspnea score at the end of first day was significantly more in the MS group [-23.8% (13.6)] compared with the placebo group [-9.4% (12.9)] (p= 0.002). The % changes in PEFRs at 10 minutes [4.7 (7.5) and -3.5 (6.0), p= 0.005] and 30 minutes [8.2 (6.7) and 1.3 (5.5), p= 0.03] were significantly greater in the MS group compared with the placebo group on the first day. No side effects developed due to MS. CONCLUSION: Nebulised MS is a cheap, feasible and safe drug that can be added to the standart bronchodilator treatment since it provides additional relief of dyspnea in patients with COPD exacerbations. This needs to be evaluated in future clinical studies including greater number of patients.

The increased transglutaminase 2 expression levels during initial tumorigenesis predict increased risk of metastasis and decreased disease-free and cancer-specific survivals in renal cell carcinoma.

PURPOSE: The aim of this study was to investigate the role of transglutaminase 2(TG2) in renal cell carcinoma (RCC) by comparing the immunohistochemistry staining of primary and metastatic tumor tissues. METHODS: A total of 33 metastatic RCC(mRCC) and 33 non-metastatic RCC (nmRCC) patients who were matched as closely as possible based on gender, age, nuclear grade and pathologic T stage were retrospectively investigated. TG2 immunohistochemistry staining was performed on paraffin-embedded primary tumor tissues from both patient groups and on metastatic tissues from mRCC patients. The tissues were scored from 0 to 7 according to the TG2 staining. Furthermore, the patients were stratified into two groups using median primary tumor staining score as the cutoff value: Group 1 (high risk, n = 41) and Group 2(low risk, n = 22). The clinical, histopathological and survival outcomes were compared between these risk groups using Chi-square test, t test, Mann-Whitney U test and Kaplan-Meier survival analyses. RESULTS: The median TG2 score for primary tumor was 5 for the entire study population. The median primary tumor TG2 score of the mRCC patients was significantly higher compared to the nmRCC patients (6 vs. 4, p < 0.001). The TG2 score between the primary and metastatic tissues of mRCC patients was not significantly different (6 vs. 7, p = 0.086). The percentage of metastatic patients was significantly higher in Group 1 compared to Group 2 (68.3 vs. 18.2 %, p < 0.001). Kaplan-Meier analyses showed that 5-year disease-free (34.9 vs. 92.9 %, p = 0.001) and cancer-specific (47.4 vs. 86.5 %, p = 0.04) survival rates were significantly lower in high-risk group. CONCLUSIONS: The increased expression of TG2 in primary tumor predicts metastasis in RCC patients and is also associated with a decrease in disease-free and cancer-specific survival outcomes.

Copper, zinc and iron levels in infants and their mothers during the first year of life: a prospective study.

BACKGROUND: Essential micronutrients are important for maintenance of life. Deficiency of micronutrients is more likely to be encountered in children, and women studies are required to investigate the status of micronutrients in children and women. This study aimed to longitudinally evaluate changes in zinc, copper, and iron levels in breastfed infants and their mothers during the first year of life. METHODS: Serum and hair samples were obtained from 35 healthy breastfed infants (51% males, 49% females) and their mothers 2, 6, and 12 months after delivery. All of the samples were assessed using an atomic absorption spectrophotometer. Serum iron levels were determined by a Roche/Hitachi/Modular analyzer. Statistical analyses were performed using SPSS-PC (Version 21.00) software. RESULTS: Hair zinc (p < 0.05) and serum iron (p < 0.001) levels of infants were significantly decreased towards the end of the first year. Infants' serum copper levels were increased towards the end of the first year. Maternal serum and hair copper levels and serum iron levels were significantly decreased towards the end of the first year. There were no significant correlations between dietary zinc, copper, iron intake, and trace element levels of infants and their mothers. CONCLUSIONS: Infants' hair zinc levels, maternal and infants' hair copper levels, and infants' and maternal serum iron levels declined towards the end of the first year. Infants need more zinc after 6 months of age. Infants' and mothers' daily iron intake was less than the recommended intake.

Measurement of the lingual position of the lower third molar roots using cone-beam computed tomography.

PURPOSE: The aim of this study was to evaluate the distance between the roots of the impacted third molars and the floor of the mouth to predict the risk of lingual root displacement during surgery. MATERIALS AND METHODS: Thirty-one patients (5 men and 26 women) were evaluated for this study using cone-beam computed tomography (CBCT). The teeth were grouped according to their position on the orthopantomogram as vertical, mesioangular, horizontal, and distoangular. The distance between 2 points on the roots and lingual soft tissues was measured. RESULTS: The average distance between the apex of the root, which is in the most lingual position, and the lingual cortical plate was 1.03 mm. The average distance between the most lingual point on the apical half of the root, which is in closer proximity, and the lingual cortical plate was 0.65 mm. CONCLUSION: The distance between the apices and the lingual plate is very short, which allows displacement of broken roots or teeth, especially when the lingual plate is perforated.

The prevalence of Hymenoptera venom allergy in adults: the results of a very crowded city in Euroasia.

BACKGROUND: There are scarce data about the prevalence of Hymenoptera venom allergy in the general population. The aim of this study was to determine the prevalence of Hymenoptera venom allergy in the general adult population of Istanbul. METHODS: A total of 17,064 randomly selected telephone numbers were contacted and 11,816 (69.25%) individuals who agreed to participate completed a questionnaire. Those who disclosed hypersensitivity reactions due to Hymenoptera stings in this initial survey were called again and given another questionnaire. Those who were suspected of experiencing hypersensitivity reactions to Hymenoptera stings were invited for a clinical investigation with in vivo and in vitro diagnostic tests. RESULTS: According to the first questionnaire, a total of 1171 (9.9%; 95% CI: 9.38-10.47%) were suspected of having a hypersensitivity to Hymenoptera stings. 51.75% (n: 606) answered the second questionnaire and 21% (n: 128) of these were still suspected of having a hypersensitivity to Hymenoptera stings (1.1%; 95% CI: 0.9-1.29%). The confirmed prevalence of hypersensitivity to Hymenoptera stings according to skin tests and in vitro sIgE levels was 0.2% (95% CI: 0.14-0.30%). Nearly all of the participants with systemic reactions were admitted to the emergency department, although only one tenth of them received adrenaline in the emergency room. 2.3% carried an adrenaline injector, whereas none of the patients received venom immunotherapy. CONCLUSIONS: The prevalence of Hymenoptera sting reactions in our geographical region is comparable with other European studies. There is a need to increase the awareness of adrenaline in the emergency management of insect sting anaphylaxis and venom immunotherapy in the prophylaxis.

Effects of respiratory muscle training on pulmonary functions in patients with slowly progressive neuromuscular disease: a randomized controlled trial.

OBJECTIVE: To investigate the effects of inspiratory and expiratory muscle training on pulmonary functions in patients with slowly progressive neuromuscular disease. DESIGN: Prospective randomized controlled double-blinded study. SETTING: Chest diseases clinic of university hospital. SUBJECTS: Twenty-six patients with slowly progressive neuromuscular disease followed for respiratory problems were included in the study. Patients were randomly divided into two groups; experimental (n = 14; age 31.6 ±12.3 years) and sham (n = 12; age 26.5 ±8.6 years) groups. METHODS: Spirometry, peak cough flow, maximal inspiratory pressure, maximal expiratory pressure, and sniff nasal inspiratory pressure were measured before the eighth week of study, and subsequently at end of it. Respiratory muscle training was performed by inspiratory (Threshold Inspiratory Muscle Trainer) and expiratory (Threshold Positive Expiratory Pressure) threshold loading methods. Training intensities were increased according to maximal inspiratory and expiratory pressures in the experimental group, while the lowest loads were used for training in the sham group. Patients performed 15 minutes inspiratory muscle training and 15 minutes expiratory muscle training, twice a day, five days/week, for a total of eight weeks at home. Training intensity was adjusted in the training group once a week. RESULTS: Maximal inspiratory and expiratory pressures (cmH2O, % predicted) (respectively p = 0.002, p = 0.003, p = 0.04, p = 0.03) and sniff nasal inspiratory pressure (p = 0.04) were improved in the experimental group when compared with the sham group. However, there was no improvement in spirometric measurements when groups were compared (p > 0.05). CONCLUSIONS: As a conclusion of our study, we found that respiratory muscle strength improved by inspiratory and expiratory muscle training in patients with slowly progressive neuromuscular disease.

Effects of hemostatic agents on fibroblast cells.

PURPOSE: Hemostatic agents may be used topically to control hemorrhage, especially in patients with bleeding disorders. The agent used may have a negative effect on the tissue prolonging the healing time. The aim of this study was to compare the effects of 3 different hemostatic agents on fibroblast cells on a rat primary fibroblast cell culture model. MATERIALS AND METHODS: Ankaferd Blood Stopper (ABD) (Ankaferd Pharmaceuticals Cosmetics Production and Marketing Co.), fibrin glue, and tranexamic acid were the agents to be evaluated for their effects on cell proliferation, cell numbers, cell viability, and cell morphology. Also lactate dehydrogenase, basic fibroblast growth factor, and vascular endothelial growth factor C levels were measured. RESULTS: It was found that all of the agents used in the study have negative effects on fibroblasts, with ABD having the lowest values of cell proliferation, cell number, and cell viability. CONCLUSION: The results of this study indicate that ABD, fibrin glue, and tranexamic acid may negatively affect tissue healing.

Effect of smoking and indoor air pollution on the risk of tuberculosis: smoking, indoor air pollution and tuberculosis.

INTRODUCTION: Although epidemiological studies have reported an association between smoking and increases in tuberculosis, the relationship between indoor air pollution and risk of tuberculosis is not fully understood. A limited number of studies have suggested that smoking and indoor air pollution may play a role in the pathogenesis of tuberculosis. In this study, we investigated the effect of smoking and indoor air pollution on the risk of active tuberculosis. MATERIALS AND METHODS: It is prospectively recorded age matched case-control study. Three hundred sixty two active tuberculosis cases and 409 healthy controls were included to the study. All participants were interviewed face to face by using a questionnaire including smoking habit, quantity and duration of smoking, number of room/person in the house, monthly income of the family, indoor heating system, and environmental tobacco smoke. RESULTS: Patients who smoke had a five fold (95% CI: 3.2-7.5, p< 0.0001) higher odds of having active tuberculosis compared with patients who do not smoke. Similarly, patients using coal or wood for indoor heating had a 1.6 fold (95% CI: 1.179-2.305, p< 0.003) higher odds having tuberculosis. People who have less income (< 200 Euro/month) had 3.2 fold (95% CI: 2.113-5.106, p< 0.0001) higher odds of having tuberculosis compared with people having high income. There was a significant correlation between heavy smoking (≥ 20 packet/year, p< 0.0001) and age onset of smoking (< 16 years of age, p< 0.041). There was no significant association between environmental tobacco smoke and tuberculosis. CONCLUSION: Smoking and indoor air pollution may increase the risk of tuberculosis. There is a complex interaction between smoking, socioeconomic conditions, indoor air quality and tuberculosis. Our results suggest that effective indoor air quality control could help to prevent tuberculosis risk.

Service Quality and Related Factors in Primary Health Care Services: A Cross-Sectional Study.

Primary health care services aim to prevent diseases and improve health efficiently and effectively. This study measures perceived service quality in a primary healthcare organization and examines the effect of personality traits on service quality. The cross-sectional study population comprised individuals over the age of 18 who applied to the Bingöl Central Community Health Centre. A total of 460 participants were included in the study between November 2018 and March 2019. The participants completed a face-to-face questionnaire that included socio-demographic characteristics, the SERVQUAL Scale, and an abbreviated form of the revised Eysenck Personality Questionnaire. This study is based on doctoral research in public health. The study found median values for personality trait sub-dimensions as follows: neuroticism: 2, psychoticism: 2.65, extraversion: 4, and lying: 5. The SERVQUAL Score was -0.02. The study revealed that the quality of primary health care services did not meet the participants' expectations. The study findings also indicated that age, educational attainment, and extraverted and psychotic personality traits were significantly associated with the satisfaction of service quality expectations (p < 0.05). It is recommended to provide primary health care services in facilities with good physical characteristics, with sufficient and competent health personnel, and in a timely and accurate manner to improve service quality.

Perceived levels of corporate support, colleague support and anxiety in motor courier employees.

OBJECTIVE: The use of motorcycles in commercial transportation is increasing due to its comfortable use in congested traffic conditions and the ease of parking on narrow streets. Motorcycle couriers are among the important members of the delivery industry. The race against time and delivering on time bring along many problems. This study aims to examine the relationships between perceived organizational support, colleague value and stress in motor courier employees. METHOD: Within the scope of the study, 151 motorcycle couriers working in the delivery sector were selected. The study was carried out in the period of June-November 2022. In addition to 15 questions including demographic characteristics with the one-to-one interview method, Spielberger's State and Trait Anxiety Scale, The Perceived Organizational Support Scale and The Coworker Support Scale were applied with the one-to-one interview method. RESULTS: The average age of the 151 couriers included in the study was 29.10 ± 7.01; the working year was 3.26 ± 3.39; the average number of daily trips was 36.47 ± 17.37; the average delivery time was 16.54 ± 10.10 in minutes (median 15); and the average weight of the cargo was 4.94 ± 5.51 (kg) (median: 3.50). The prevalence of occupational accidents in the last year has been 43.3% (n = 61). Examining the causes of the prevalence of accident among the study population, it was found that motorcycle overturning was 20 (32.8%); vehicle hitting the motorcycle was 26 (42.6%); motorcycle hitting the vehicle was 15 (24.6%). When the factors affecting the perceived organizational support were examined, it was found that those with a colleague social support score above 18 were more likely to have an organizational perception score above 80 (95% CI 1.001-4.843) with a rate of [OR] = 2.20 times higher, and those with a status anxiety score above 40 were more likely to have an organizational perception score over 80 with a rate of [OR] = 2.49 times higher (95% CI: 1.156-5.364). In addition, it was seen that the probability of having an organizational perception score above 80 was [OR] = 0.42 times higher (95%CI: 0.200-0.889) in participants who had a work accident. CONCLUSIONS: The intense pace of work and the pressure of fast delivery increase couriers' state and trait concerns. Developing policies to improve the psychosocial working environment for a more decent and healthier working environment that improves the mental health and well-being of couriers is recommended. Commercial food ordering platforms must treat driver safety as important when determining delivery times.
