The Relationship Between Premenstrual Syndrome and Dietary Habits and Nutrients Intake: Descriptive and Analytical Cross- Sectional Study

Objective: This study aimed to examine the relationship between premenstrual syndrome (PMS) and nutrition in nursing students. Methods: This is a descriptive and analytical cross-sectional study evaluating the relationship between premenstrual syndrome and nutrition in nursing students. In this descriptive and cross-sectional study, relationship between nutrient and PMS was examined by 219 nursing students using personal information form, 24-hour food consumption record and Premenstrual Syndrome Scale (PMSS). The macro and micronutrients consumed by the participants were determined through the analysis of their food consumption records in the Nutrition Information System (BEBIS) program. T test, chi-square test and Pearson correlation analysis test were used in analysis of data. Results: It was determined that 53.4% of the students had PMS and dietary habits are important in the appearance of PMS symptoms. Breakfast and lunch consumption affected the presence of PMS, but there was no difference between the groups with and without PMS in terms of coffee, salt consumption and skipping meals. The total energy taken daily by the female students with PMS were higher, percentage of energy from protein was lower and difference was statistically significant (p

THE RELATIONSHIP BETWEEN UNIVERSITY STUDENTS' CONSCIOUS AWARENESS, HOPE LEVELS, LIFE SATISFIED

The aim of this study is to reveal the relationship between university students' levels of mindfulness, life satisfaction and hope. In the study, the relational survey model was used to examine university students in terms of mindfulness, life satisfaction and hope levels. The study group of the research consists of 201 university students, 138 female and 63 male, studying at Mehmet Akif Ersoy University in the fall semester of the 2022-2023 academic year. Research data were collected using the "Cognitive and Affective Awareness Scale", "Continuous Hope Scale", "Life Satisfaction Scale", and personal information form. As a result of the Pearson Correlation analysis test, it was determined that there was a positive and significant relationship between university students' mindfulness, life satisfaction and hope levels. According to the research findings, it is seen that there is a positive and significant relationship between university students' mindfulness, life satisfaction and hope levels. While it is seen that there is a low level of positive and significant relationship between mindfulness and hope level; There is a significant and positive moderate relationship between mindfulness and life satisfaction. Looking at the results, it can be said that as the level of conscious awareness of university students increases, their life satisfaction and hope levels increase.

ANALISIS FAKTOR RESIKO STROKE AKTIVITAS FISIK REMAJA OBESITAS DI KOTA MALANG

Overweight and obesity in developing countries is a health problem. An increase in body mass index associated with an increase in inflammatory media, hypertension, diabetes mellitus, hypercholesterolemia especially LDL and hypertriglycerides is thought to be a trigger for stroke. Obesity can occur as a result of light physical activity due to an imbalance between energy expenditure and calorie intake. The analytic observational research method used a cross sectional design. The study population was overweight and obese adolescents aged 10-19 years. Nonprobability sampling technique (accidental sampling) with 60 respondents. Data analysis with Pearson's correlation analysis test and discriminant analysis test. Physical activity is a risk factor for stroke in obese adolescents with a sig value of 0.015 where obese adolescents who have low physical activity have a 2 times greater risk of stroke than obese adolescents who have moderate or high activity. Physical activity is not only important for losing weight but for reducing the risk due to increased body weight, one of which is stroke.

Determination of the relationship between physician trust, medical mistrust, and self-confidence in the health services provided in Turkey

Objectives: A sense of trust is of great importance for professional professions. Failure to establish trust, especially in an industry where information asymmetry is too high, such as the health sector, also poses important problems for both employees and society. In this study, we aimed to identify variables that affect the distrust of the health system and trust in the physician.
 Material and Method: This study was carried out in the descriptive design. The study group consisted of 561 people living in different cities of Turkey and whose ages ranged from 18-70 years. “Personal data form”, “ Medical mistrust scale”, “Physician trust scale” and “generalized trust inventory infrastructure scale” were used as data collection tools prepared by the researcher. As a data collection method, the test method performed in a computer environment was used. One-way analysis of variance from parametric test statistics and Pearson correlation analysis test statistics were used to compare data. P<0.050 and p<0.001 were determined for the significance level.
 Results: In our study, medical mistrust decreased as trust in the physician increased. As a person's level of self-trust increases, medical mistrust increases, and confidence in the physician also decrease. Dissatisfaction with the health service increases medical mistrust, while also reducing trust in the physician. Based on the preferred type of hospital, the level of medical mistrust of patients going to private hospitals is greater than the level of medical mistrust of patients going to public hospitals.
 Conclusion: This study reveals the importance of trust in the health sector and the factors that affect it. More detailed studies on practices that will increase confidence in the importance of this issue and measures that will reduce distrust will make a great contribution to this issue.

Selective impairment of musical emotion recognition in patients with amnesic mild cognitive impairment and mild to moderate Alzheimer disease.

BackgroundPatients with Alzheimer disease (AD) and amnesic mild cognitive impairment (aMCI) have deficits in emotion recognition. However, it has not yet been determined whether patients with AD and aMCI also experience difficulty in recognizing the emotions conveyed by music. This study was conducted to investigate whether musical emotion recognition is impaired or retained in patients with AD and aMCI.MethodsAll patients were recruited from the First Affiliated Hospital of Anhui Medical University between March 1, 2015 and January 31, 2017. Using the musical emotion recognition test, patients with AD (n = 16), patients with aMCI (n = 19), and healthy controls (HCs, n = 16) were required to choose one of four emotional labels (happy, sad, peaceful, and fearful) that matched each musical excerpt. Emotion recognition scores in three groups were compared using one-way analysis of variance (ANOVA) test. We also investigated the relationship between the emotion recognition scores and Mini-Mental State Examination (MMSE) using Pearson's correlation analysis test in patients with AD and aMCI.ResultsCompared to the HC group, both of the patient groups showed deficits in the recognition of fearful musical emotions (HC: 7.88 ± 1.36; aMCI: 5.05 ± 2.34; AD: 3.69 ± 2.02), with results of a one-way ANOVA confirming a significant main effect of group (F(2,50) = 18.70, P < 0.001). No significant differences were present among the three groups for the happy (F(2,50)=2.57, P = 0.09), peaceful (F(2,50) = 0.38, P = 0.09), or sad (F(2,50) = 2.50, P = 0.09) musical emotions. The recognition of fearful musical emotion was positively associated with general cognition, which was evaluated by MMSE in patients with AD and aMCI (r = 0.578, P < 0.001). The correlations between the MMSE scores and recognition of the remaining emotions were not significant (happy, r = 0.228, P = 0.11; peaceful, r = 0.047, P = 0.74; sad, r = 0.207, P = 0.15).ConclusionThis study showed that both patients with AD and aMCI had decreased ability to distinguish fearful emotions, which might be correlated with diminished cognitive function.

The Level of Hopelessness and Psychological Distress among Abused Women in A Women's Shelter in Turkey

Hopelessness prevents abused women from participating in social life and increases the risk of suicide. The aim of this study was to determine the level of hopelessness and psychological distress among abused women admitted to shelter in a conservative country. The sample included 40 abused women. A questionnaire, Beck Hopelessness Scale and the General Health Questionnaire were used to collect data. Chi-square, the Pearson correlation analysis test, and variance analysis were performed. Half of the women experienced moderate and severe hopelessness. Higher levels of hopelessness were found to be associated with higher psychological distress. Women had problems with decision-making, concentrating on a job, felt unhappiness, and depression. The results of the study would be useful in designing training programs for nurses, social workers and counselors as well as policy makers who assist women facing domestic violence to provide better physiological and psychological care for sheltered women in conservative countries.

Effect of Vasoactive Therapy Used for Brain-Dead Donors on Graft Survival After Kidney Transplantation

Serum catecholamine levels and peripheral vascular resistance decrease after brain death. Vasoactive drugs are used to control these hemodynamic changes and to improve perfusion of the organs. These drugs might have a role in rejection or loss of the graft organ. We aimed to investigate the effects of vasoactive drugs used in the cadaveric donor care on post-transplant renal graft functions. In this retrospective study, medical records of 135 cadaveric donors (270 kidneys) and recipients of these kidneys were evaluated. Correlation analysis was done to assess the data for factors that may cause rejection and graft loss. Vasoactive drug (noradrenaline 49%, dopamine 60%, adrenaline 3%, dobutamine 11%) consumption ratio was 85.8% in donor care. Increased number of noradrenaline infusion days was associated with decreased rates of graft rejection and graft loss. This correlation was not found for dopamine. Results of the Pearson correlation analysis test showed a relation between noradrenaline use and decrease in graft loss and graft rejection. Noradrenaline but not dopamine used in cadaveric donor care decreased the graft rejection rate and graft loss, presumably by improving hemodynamic stability and organ perfusion, although we found no special reason.

Effects of the land use/cover on the surface runoff and soil loss in the Niğde-Akkaya Dam Watershed, Turkey

Erosion, flood, and overflow events are frequently experienced due to changes in the land use in watersheds where human impacts are intensive. It is important to understand the effects of land use types on erosion at a watershed scale. This knowledge can then be used to manage soil and water resources in watersheds better. The aim of this study is to determine the effects of different land uses/covers on the surface runoff and soil loss by using a rainfall simulator in natural land conditions in the Niğde Akkaya Dam watershed with semi-arid conditions. For this purpose, 5 cultivated lands with different product patterns with similar conditions (apple orchard (A), potato cultivation area (P), bean cultivation area (B), clover cultivated land (CL), abandoned cultivated land (AB), plantation areas (cedar (C) and almond (AL)), and pasturelands covered with Thymus sp. (T), Agropyron sp. (AG) and Stipa sp. (S) were selected for the applications. The applications were carried out in two repetitions on circular test parcels of 0.28m2 established in these lands. During the land applications, the characteristics of surface runoff (ponding time, surface runoff start time, average surface runoff rate, runoff coefficient) and the average sediment concentration in the surface runoff water were determined. The data obtained were evaluated by using the ANOVA, Duncan's test, and Pearson correlation analysis test and SPSS statistical program. The results of the study revealed that the surface runoff occurred in the abandoned cultivation area, bean cultivation area, potato cultivation area, and thyme-covered pastureland in a short time. The runoff coefficient values by the land cover are sorted from high to low as B>T>P>A>AB>AL>C>CL>S>AG. The sediment concentration in the runoff water is sorted from high to low as T>P>B>AB>AL>A>C>S. When the situation was evaluated in terms of the soil loss (erosion), it was concluded that the sorting is as P>T>A>AB>B>AL>C>S>CL.

The effect of histone deacetylase inhibition on the expression of P-glycoprotein in human placental trophoblast cell lines

IntroductionsPlacental P-glycoprotein (P-gp), encoded by ABCB1 gene in human, plays a significant role in regulating drugs' transplacental transfer rates. Investigations on placental P-gp regulation could provide more therapeutic targets for individualized and safe pharmacotherapy during pregnancy. Currently, the epigenetic control of placental P-gp is rare. This study aimed to investigate the effect of histone deacetylases (HDACs) inhibition on P-gp expression in placental trophoblast cell lines and to explore whether HDAC1/2/3 was involved in this process preliminarily. MethodsHuman placental trophoblast cell lines (Bewo and JAR) were treated with two different HDAC inhibitors-suberoylanilide hydroxamic acid (SAHA) and trichostatin A (TSA) at different concentration gradients of 0.5, 1.0, 3.0 and 5.0 μM. Cells were harvested after 24, 48, and 72 h treatment. Total HDAC activity was detected by colorimetric assay Kits. HDAC1/2/3/ABCB1 mRNA and protein expressions were determined by real-time quantitative PCR and western-blot, respectively. Pearson correlation analysis test was performed to explore the relationship between HDAC1/2/3 mRNA and ABCB1 mRNA expression. ResultsSAHA and TSA could inhibit total HDAC activity and placental HDAC1/2/3 expression both in Bewo and JAR, but displayed a transient induction of HDAC mRNA or protein level after being treated at low dosage or prolonged exposure to drugs. Discordance in HDAC mRNA and protein expression was also observed. Placental P-gp expression was significantly induced in company with HDACs inhibition. There was a significant negative linear relationship between HDAC1/2 mRNA and ABCB1 mRNA expression. ConclusionsHDACs inhibition could up-regulate placental P-gp expression in trophoblast cells, and HDAC1/2 was most likely to be involved in this process.

The Assessment of Pupil Cycle Time in Patients with Glaucoma

Purpose: To evaluate the value of pupil cycle time (PCT) measurements in patients with glaucoma. Material and Methods: 40 eyes of 40 patients having primary open angle glaucoma and 35 eyes of 35 healthy subjects were enrolled in this study. In unilateral cases the glaucomatous was studied and in bilateral cases the studied eye was determined randomly in both groups when both eyes were eligible. All patients underwent ophthalmologic examinations, including best corrected visual acuity (BCVA), slit-lamp biomicroscopy, Goldmann applanation tonometry, gonioscopy, visual field testing, PCT measurement and optical coherence tomography (OCT). Two groups were compared using the chi-squared test for categorical variables and with the independent t test for non-categorical parameters. Correlations of PCT results with age of patients, duration of glaucoma (years), best corrected visual acuity (BCVA), mean deviation (MD) and pattern standard deviation (PSD) of visual field and OCT parameters were analyzed with Pearson correlation analysis test. Results: Mean age was 63.5 ± 9.5 in glaucoma patients, and 62.2 ± 7.2 in healthy subjects (p=0.453). Rate of females was 62.5% in glaucoma patients, and 54.2% in healthy subjects (p=0.323). Mean PCT was 947.5 ± 65.5 ms in the glaucoma group, whereas it was 888 ± 33.8 ms in healthy subjects (p=0.030). There was a significant correlation between PCT and other variables including age of the patients (R: 0.331, p=0.001), duration of glaucoma (R: 0.457, p<0.001), BCVA (R:-0.396, p<0.001), ganglion cell-inner plexiform layer (GC-IPL) thickness (R:-0.457, p<0.001) and retinal nerve fiber layer thickness (RNFLT) (R:-0.676, p<0.001). There was a prominent lengthening of PCT while reducing BCVA, RNFLT and GC-IPL thickness. Conclusion: PCT measurements showed a significant correlation with OCT parameters in our study. Further prospective studies are needed to evaluate the value of PCT in glaucoma patients.

The relationship between managers' leadership styles and emergency medical technicians' job satisfaction.

Leadership plays a crucial role in many professions, especially in challenging positions such as emergency medical service jobs. The purpose of this study was to explore the relationship between managers' leadership styles and emergency medical technicians' job satisfaction. This is a descriptive and cross-sectional study that was carried out in 2010. The research population included 21 managers and 87 emergency medical technicians working in 23 stations in Isfahan city, Iran. The main tools used for data accumulation were the Multiple Leadership Questionnaire for evaluating leadership styles and the Job Descriptive Index for measuring job satisfaction levels. Also, the Pearson correlation analysis test was used to evaluate the relationship between leadership style and job satisfaction. Among both managers and technicians, the highest mean score related to the transformational management style, whereas the lowest mean score related to the laissez-faire management style. Moreover, a significant relationship (P<0.01) was found between the transformational and transactional leadership styles and job satisfaction. However, no significant relationship was observed between the laissez-faire management style and job satisfaction. Considering the importance of job satisfaction in medical emergencies, it is recommended that health sector policy makers should provide the groundwork for implementing the transformational leadership style to enhance job satisfaction of the medical emergency staff.

Vitamin A status of healthy children in Manisa, Turkey

BackgroundVitamin A deficiency is a major public health nutrition problem in the developing world. Even subclinical Vitamin A deficiency is associated with increased childhood mortality. Severe maternal vitamin A deficiency may cause increased mortality in the first months of life. There have been a limited number of studies regarding vitamin A status in Turkey. The aim of this study was to assess vitamin A status of healthy children in Manisa, Turkey.MethodsVitamin A status of 100 healthy children aged 36-48 months is evaluated. The children were seen during routine examination. Serum retinol concentrations were measured by high-performance liquid chromatography. Duration of breast feeding, age solid foods introduced, use of supplementary vitamins, weight and height, and intake of specific groups of nutrients on a daily, weekly and monthly basis were collected from a questionnaire completed by the mothers. Height and weight z-scores were calculated according to national standards. Mothers of 20 of the 100 children were known to have normal serum and breast milk retinol concentrations. Children with normal serum retinol concentration were compared with the children with VAD. Student's t-test and Mann-Whitney test were used to compare independent variables. The Pearson correlation analysis test was used to test relation between numeric variables.ResultsMean retinol concentration was 0.98 ± 0.32 μmol/L in the whole study group. Serum retinol concentrations were normal (>0.70 μmol/L) in 89% of the children. When children with normal serum retinol concentrations were compared with those with retinol concentrations lower than 0.70 μmol/L, there was no difference in terms of age, gender, weight and height at the time of study, z-scores, birth weight, birth length, duration of breast feeding, time to begin solid food, rate of supplementary vitamin use, and rate of infections (P > 0.05). There was not any relation between vitamin A concentrations and weight and height at the time of study, z-scores, birth weight, birth length, duration of breast feeding, time to begin solid food, vitamin use, and frequency of intake of specific groups of nutrients (P > 0.05).ConclusionsThis study showed that VAD is a moderate health problem in Manisa.

Preoperative determination of prostate cancer tumor volume: analysis through biopsy fragments

Preoperative determination of prostate cancer (PCa) tumor volume (TV) is still a big challenge. We have assessed variables obtained in prostatic biopsy aiming at determining which is the best method to predict the TV in radical prostatectomy (RP) specimens. Biopsy findings of 162 men with PCa submitted to radical prostatectomy were revised. Preoperative characteristics, such as PSA, the percentage of positive fragments (PPF), the total percentage of cancer in the biopsy (TPC), the maximum percentage of cancer in a fragment (MPC), the presence of perineural invasion (PNI) and the Gleason score were correlated with postoperative surgical findings through an univariate analysis of a linear regression model. The TV correlated significantly to the PPF, TPC, MPC, PSA and to the presence of PNI (p < 0.001). However, the Pearson correlation analysis test showed an R2 of only 24%, 12%, 17% and 9% for the PPF, TPC, MPC, and PSA respectively. The combination of the PPF with the PSA and the PNI analysis showed to be a better model to predict the TV (R2 of 32.3%). The TV could be determined through the formula: Volume = 1.108 + 0.203 x PSA + 0.066 x PPF + 2.193 x PNI. The PPF seems to be better than the TPC and the MPC to predict the TV in the surgical specimen. Due to the weak correlation between those variables and the TV, the PSA and the presence of PNI should be used together.

Neurotransmitter Levels in Cerebrospinal Fluid in Relation to Severity of Symptoms and Response to Medical Therapy in Parkinson's Disease

Determinations of biopterin (BP), homovanilic acid (HVA), glutamic acid (GTA), and glutamine (GT) levels in cerebrospinal fluid (CSF) obtained through a lumbar tap were performed in 20 parkinsonian patients in different stages of evolution and without medication. In patients with motor symptoms not related to Parkinson's disease (dystonia, dyskinesia and essential tremor) (n = 4). In 7 other neurological patients subjected to spinal tap for diagnostic procedures neurotransmitters were also determined and taken as control groups. In 14 of the patients with Parkinson's disease, the symptoms were evaluated using conventional scales (UPDS, NYPDS, NWPDS, Schwab and England, and Hoehn and Yahr scale). The amplitude and the frequency of tremor were quantitatively evaluated through a single plane accelerometer Grass SP-1, akinesia was measured through reaction time to auditory stimuli, and rigidity through the speed of lineal movement. Evaluations were performed with the patient not on any medication for 1 week and repeated 1 h after the intake of 250 mg of 200/50 L-dopa/carbidopa preparation (Sinemet) and on a different day after the intake of biperiden (Akineton) 6 mg/day. Differences in neurotransmitter or metabolites levels between Parkinson's disease and control groups were determined through an independent Student's t test. Correlation between severity of symptoms in the scales and for each individual symptom measured through the quantitative tests and the levels of neurotransmitters in CSF were evaluated through the Pearson correlation analysis test. Modifications in the motor performance after administration of Sinemet and Akineton, and the levels of neurotransmitters were indirectly determined. RESULTS. (1) There were significant differences between the levels of BP and GT in patients with Parkinson's disease and control groups, (2) lower GTA levels correlated with more severe rigidity and akinesia, and with the best response to the administration of L-dopa and may be an important marker for prognosis, and (3) lower levels of GT correlated with least akinesia, but not with tremor, which may indicate that the akinesia depends on other biochemical abnormalities besides dopamine depletion.
