The long-term effects of topical latanoprost 0.005% treatment on pupillary functions: A 2-year longitudinal study.

PURPOSE: To investigate the long-term effects of topical latanoprost 0.005% treatment on pupillary functions in early-stage primary open-angle glaucoma (POAG) eyes using automated pupillometry. METHODS: This prospective study involved 20 eyes of 20 treatment-naive subjects with early-stage POAG. After comprehensive ophthalmic examination, static and dynamic pupillometry measurements were performedbefore treatment, at the 1st follow-up visit (1.10 ± 0.30 months) and the 2nd follow-up visit (25.85 ± 10.26 months) after treatment initiation. Dynamic parameters included resting diameter (mm), amplitude (mm), latency (ms), duration (ms), and velocity (mm/s) of pupil contraction and dilation. Static pupillometry parameters were pupil diameter (PD, mm) in high-photopic, low-photopic, mesopic and scotopic conditions. RESULTS: The velocity of pupil dilation significantly decreased during the 1st visit (p = 0.008) and the 2nd visit (p = 0.0003) of treatment compared to the pre-treatment visit. The resting PD was also significantly higher after the 1st visit (p = 0.003) and the 2nd visit (p = 0.001) compared to the pre-treatment visit. However, the difference in resting PD measured between the 1st and 2nd visits did not reach statistical significance (p = 0.065). There were no significant changes in other dynamic parameters (p > 0.05 for all). Additionally, a mild, but not significant, mydriatic effect was observed in PD measurements under scotopic, mesopic and low photopic lighting conditions after follow-up. None of the static and dynamic parameters correlate with age, changes in intraocular pressure (IOP) or mean deviation (MD) values of visual field tests. CONCLUSION: The long-term topical latanoprost 0.005% treatment in early-stage POAG has a slight mydriatic effect on the pupil. Further longitudinal clinical studies with larger patient cohorts are necessary to better understand the effects of latanoprost on pupillary functions.

Lung cancer from suspicion to treatment: An indicator of healthcare access in Turkey.

BACKGROUND: Lung cancer is the leading cause of cancer-related deaths worldwide. Before beginning lung cancer treatment, it is necessary to complete procedures such as suspecting lung cancer, obtaining a pathologic diagnosis, and staging. This study aimed to investigate the processes from suspicion of lung cancer to diagnosis, staging, and treatment initiation. METHODS: The study was designed as a multicenter and cross-sectional study. Patients with lung cancer from various health institutions located in all geographic regions of Turkey were included in the study. The sociodemographic and clinical characteristics of the patients, the characteristics of the health institutions and geographic regions, and other variables of the lung cancer process were recorded. The time from suspicion of lung cancer to pathologic diagnosis, radiologic staging, and treatment initiation, as well as influencing factors, were investigated. RESULTS: The study included 1410 patients from 29 different medical centers. The mean time from the initial suspicion of lung cancer to the pathologic diagnosis was 48.0 ± 52.6 days, 39.0 ± 52.7 days for radiologic staging, and 74.9 ± 65.5 days for treatment initiation. The residential areas with the most suspected lung cancer cases were highly developed socioeconomic zones. Primary healthcare services accounted for only 0.4% of patients with suspected lung cancer. The time to pathologic diagnosis was longer in the Marmara region, and the wait time for staging and treatment initiation was longer in Eastern and Southeastern Anatolia. Patients who presented to chest disease referral hospitals with peripheral lesions, those with early-stage disease, and those who were diagnosed surgically had significantly longer wait times. CONCLUSION: The time between pathologic diagnosis, staging, and treatment initiation in lung cancer was longer than expected. Increasing the role of primary healthcare services and distributing socioeconomic resources more equally will contribute to shortening the time to diagnosis and improve treatment processes for lung cancer.

[Efficacy of Homologous and Heterologous Vaccine Applications on SARS-CoV-2 Omicron Variant: Cohort of Manisa Celal Bayar University Healthcare Workers]. / Homolog ve Heterolog Asi Uygulamalarinin SARS-CoV-2 Omicron Varyanti Üzerindeki Etkililigi: Manisa Celal Bayar Üniversitesi Saglik Çalisanlari Kohordu.

This study was aimed to determine the efficacy of homologous (only CoronaVac or only Pfizer-BioNTech) and heterologous (CoronaVac and Pfizer-BioNTech) vaccines during the period when the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) Omicron variant was dominant in Türkiye. Coronavirus disease-2019 (COVID-2019) infection was confirmed by reverse transcriptase polymerase chain reaction and data on vaccination status against COVID-19 were evaluated during the period of 15 January 2022-1 May 2022 when the SARS-CoV-2 Omicron variant was dominant among 1854 employees followed in the SARS-CoV-2 Vaccine Cohort of Manisa Celal Bayar University (MCBU) Hospital Health Workers. Two separate reference groups were used in the evaluation of vaccine efficacy: those who were never vaccinated and those who received only two doses of CoronaVac. The efficacy of homologous and heterologous vaccine models was evaluated with relative risks and attributable risk percentages. MS Excel, SPSS 23.0 and STATA 14.1 package programs were used for statistical analysis. The mean age of the participants was 36.6 ± 10.0. During the period from January 15th to May 1st 2022, 372 hospital workers were infected with COVID-19. Taking the never vaccinated as the reference group, the most effective model was found to be only the three or more doses of the Pfizer-BioNTech primary vaccination model (85.8%, 95% CI= 40.7-96.6). Models consisting of a single dose of CoronaVac (6.5%, 95% CI= -56.3-44.2) or a single dose of Pfizer-BioNTech (17.7%, 95% CI= -30.2-48.0) booster dose administered after two doses of primary CoronaVac vaccination was not found to be effective against the SARS-CoV-2 Omicron variant. When only two doses of primary CoronaVac vaccination model was taken as the reference group, the model consisting of two doses CoronaVac followed by two Pfizer-BioNTech booster doses was effective as 38.4% (95% CI= 15.4-55.3), whereas three doses of Pfizer-BioNTech booster model was effective as 56.4% (95% CI= 33.9-71.3). To conclude, none of the models other than the homologous or heterologous vaccine models containing at least three doses of Pfizer-BioNTech vaccine were effective compared to those unvaccinated. Compared with those who received only two doses of primary Coronavac, models with at least three doses of Pfizer-BioNTech reminder doses were more effective against the Omicron variant than other models.

[Factors Affecting Side Effects, Seroconversion Rates and Antibody Response After Inactivated SARS-CoV-2 Vaccination in Healthcare Workers]. / Saglik Çalisanlarinda Inaktif SARS-CoV-2 Asilamasi Sonrasi Yan Etkiler, Serokonversiyon Oranlari ve Antikor Yanitini Etkileyen Faktörler.

In this study, it was aimed to prospectively evaluate the efficacy, side effects and seroconversion data of inactive severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), CoronaVac® (Sinovac, China) vaccine in healthcare workers. A total of 1053 healthcare workers who were initially seronegative (COV2T® SARS-CoV-2 Total Siemens, USA) and vaccinated with inactivated SARS-CoV-2 were included in the study. Quantitative IgG antibodies (ADVIA Centaur® SARS-CoV-2 IgG, Siemens, USA) were investigated 28 days after the first vaccine (n= 939) and the second vaccine (n= 771). In addition, neutralizing antibodies were evaluated via "enzyme linked immunosorbent assay (ELISA)" test (ACE2-RBD Neutralization Assay, Dia-Pro, Italy) 28 days after the first vaccine. Antibody response of the vaccine was evaluated statistically by univariate (Chi-square, Fisher's exact test, Student's t test, Mann-Whitney U, one-way ANOVA and Kruskall Wallis ANOVA tests) analysis and linear regression models. The consistency between quantitative IgG test and neutralizing antibody test was also evaluated in blood samples taken 28 days after second vaccination. Statistical analysis was determined in logarithmically transformed data with statistical analysis with SPSS 23.0 and Stata, and type 1 error level was accepted as 0.05. At least one side effect was reported by 31.3% and 26.8% of the participants after the first and second vaccine, respectively. The most frequent side effect was pain at the injection site with a frequency of 20.4% vs 21.7%. The frequency of applying to a health center due to side effects was 1.0% after the first vaccine and 0.8% after the second vaccine. The percentage of those who produced sufficient quantitative IgG was found as 25.3% (95% CI= 22.5-28.1) 28 days after the first vaccine and 97.9% (95% CI= 96.91- 98.93) after the second vaccine. Neutralizing test antibody positivity was found as 97.7% 28 days after the second vaccine. In univariate analysis, the characteristics that significantly increased the quantitative IgG response against inactivated SARS-CoV-2 vaccine were young age (p<0.01), female gender (p<0.01), being a non smoker (p<0.001), not having a chronic disease (p= 0.019), having had the flu vaccine this year (p= 0.012), not being overweight or obese (p= 0.020), and having a SARS-CoV2 infection prior to vaccination (p<0.001). In addition, allied health personnel showed significantly lower antibody responses than the other workers (p<0.001). Multiple linear regression models revealed that, female gender, younger age, smoking and previous COVID-19 polymerase chain reaction test positivity significantly affected the quantitative IgG response after vaccination. A 99% agreement was found between the ELISA-based neutralizing antibody test and the quantitative IgG test (Kappa p= 0.783) performed on the 28th day after the second vaccination. CoronaVac® provides adequate antibody response in 25% of healthcare workers aged 18-64, after 28 days from a single vaccine, and 97% after 28 days from the second vaccine. Antibody response was significantly higher in younger ages, women, non-smokers, and those who had previously encountered SARS-CoV-2. Phase 3 and phase 4 results are needed to Show effectiveness of this vaccine in real life.

Should we worry about the eyes of celiac patients?

PURPOSE: In this article, we evaluate subfoveal choroidal thickness in celiac patients with respect to adherence to the gluten-free diet and nonadherence to the gluten-free diet, comparing with age and sex matched healthy controls using spectral-domain optical coherence tomography. MATERIALS AND METHODS: A case-control study among 42 celiac patients and 42 healthy participants was conducted in the Department of Pediatric Gastroenterology. Celiac patients of our policlinics compliant with spectral-domain optical coherence tomography examination enrolled in the study. Celiac patients had been asked verbally about their adherence to gluten-free diet, were evaluated according to negative or positive EmA and anti-TG2 for defining adherence, and were divided into two groups (adherence to gluten-free diet and nonadherence to gluten-free diet). RESULTS: Subfoveal choroidal thickness was thinner in EmA (+) or anti-TG2 (+) eyes than EmA(-) or anti-TG2 (-) eyes in celiac patients, but it was not statistically significant. The mean subfoveal choroidal thickness values in eyes with celiac disease, whose diagnosis time was longer than 60 months, were thinner than shorter group. Longer duration of gluten-free diet was associated with adherence difficulty and thinner choroidal thickness (r = -0.15, p = 0.34). Adherence to gluten-free diet was 88.2% for children below the age of 60 months and 57.1% for children older than 60 months. CONCLUSION: In conclusion, in addition to other extraintestinal manifestations of celiac disease, diagnosis time longer than 60 months in pediatric celiac patients, nonadherence to the gluten-free diet, and antibody positivity should be focused on during ophthalmologic examination and choroid measurement.

Mental health of both child and parents plays a larger role in the health-related quality of life of obese and overweight children.

Aims A decrease in health-related quality of life (HRQOL) measures among obese (OB) and overweight (OW) children has been shown in several studies, but knowledge about the variables affecting HRQOL impairments is missing. The aim of this study was to evaluate the relationship between HRQOL and sociodemographic characteristics, anthropometric measurements, metabolic parameters, mental symptoms and parental attitudes in a sample of OB/OW children. Methods Eighty-six OB/OW children, aged between 9 and 17 years, participated in the study. We performed sociodemographic questioning, anthropometric examinations and laboratory evaluations of the participants. HRQOL was assessed using the Pediatric Quality-of-Life Inventory (PedsQL), and levels of anxiety and depressive symptoms were measured using the Screen for Child Anxiety-Related Disorders (SCARED) questionnaire and the Children's Depression Inventory (CDI), respectively. Parental attitudes were assessed with the Parental Attitude Research Instrument (PARI) questionnaire. Results A statistically significant relationship was found between total scores of CDI and SCARED answered by children and the total and subscale scores of PedsQL. Scores of total quality of life subscale, physical functionality and emotional functionality subscales were significantly lower in children with a family history of mental illness. No relationship was found between PedsQL subscales, anthropometric and metabolic parameters. Conclusions Emotional problems and parental psychological distress are important factors in models of HRQOL in the OB/OW pediatric population.

Psychometric Properties of the Turkish Version of the World Health Organization Quality of Life Instrument for People with Intellectual and Physical Disabilities (WHOQOL-DIS-TR).

OBJECTIVE: The aim of this paper is to present the validity and reliability of the Turkish version of the add-on module for the WHOQOL measures of quality of life for use with adults having physical or intellectual disabilities known as the WHOQOL-DIS. METHODS: Data were collected from 150 Intellectual Disabled (ID) and 157 Physically Disabled (PD) persons in Turkey (Izmir) participating center of the global WHOQOL-DIS project. WHOQOL-DIS module is consisted of 12 disability specific items in addition to 26 generic items of WHOQOL-Bref. The proposed factorial structure (3 factors) of WHOQOL-DIS global study used in the psychometric analyses of the Turkish versions of WHOQOL-DIS. Reliability analyses and construct validity was tested via CFA analyses and convergent and discriminant validity analyses were assessed in relation to SWLS and WHODAS-II respectively. RESULTS: Cronbach alpha values of the WHOQOL-DIS factors were as follows for ID and PD samples respectively: Factor 1 (Discrimination and support)= 0.54 and 0.64; Factor 2 (Independence)= 0.78 and 0.79 ; Factor 3 (Community participation)= 0.88 and 0.83. CFI and RMSEA values were 0.98 and 0.065 for ID sample and 0.98 ve 0.064 for PD sample respectively. Convergent-discriminant validities were satisfactory for all factors in PD group (r= 0.27 - 0.62) whereas Factor 1 was not found discriminative in the ID group (r= 0.09 -0.10). CONCLUSION: Psychometric properties provided satisfactory evidence  of reliability and validity of the Turkish version of WHOQOL-DIS. Nevertheless the results of Factor 1 (Discrimination and support) in ID persons should be interpreted with caution.

Turkish validity and reliability of Eustachian tube dysfunction questionnaire-7.

INTRODUCTION: During clinical evaluations, in order to interpret patients' complaints caused by Eustachian tube dysfunction and to monitor the success of the treatment, standardized and disease-related scales are necessary. OBJECTIVE: The aim of this study was to investigate the validity and reliability of the Turkish version of Eustachian tube dysfunction questionnaire-7. METHODS: Forty patients diagnosed with Eustachian tube dysfunction and 40 healthy individuals were enrolled for the study. After language validation of the Eustachian tube dysfunction questionnaire-7 for Turkish, a scale was completed by the both Eustachian tube dysfunction and control groups. Two weeks after the first evaluation, 15 of the cases filled out the scale again without any treatment intervention. Known-groups method was used in validity analysis. Floor-ceiling effect, test-retest method, item-total score correlation and internal consistency analysis were used in reliability analyses. RESULTS: Cronbach's alpha coefficient was 0.714 for the entire questionnaire. The test-retest reliability coefficient for the total scale was determined as 0.792, indicating correlation between the two questionnaires completed by the same patient over time. In the Eustachian tube dysfunction group, total and each item scores were found significantly higher than the control group (p<0.001). CONCLUSION: The Turkish version of Eustachian tube dysfunction questionnaire-7 was found to be highly valid and reliable. This scale is recommended to use for screening of Eustachian tube dysfunction and evaluating treatment outcome.

Hemodynamic Changes in Paramedian Forehead Flap.

Paramedian forehead flap is a workhorse for nasal reconstruction. However, vascular complications may lead to flap failure. The purpose of this study was to evaluate the blood flow objectively and determine the hemodynamic changes in paramedian forehead flap with respect to influential factors of age, gender, and smoking. Thirty patients who had paramedian forehead flap were followed up prospectively between 2010 and 2013. The blood flow was assessed by resistance index using Color Duplex-Doppler Ultrasonography. Resistance index was measured at the proximal and distal ends of each flap on the postoperative first day, first week, and second week. All data were analyzed using SPSS 15.0 for Windows. Fifteen patients were female and the mean of age was 60.9 years. Our results demonstrated statistically significant differences with gradual decreases in resistance to blood flow, when the resistance index values at the proximal and distal ends of paramedian forehead flap were compared (P < 0.001 and P < 0.001). Age, gender, and smoking did not have a negative impact on the resistance index values of paramedian forehead flap. To the best of our knowledge, this is the first study in which resistance in blood flow and hemodynamic changes of paramedian forehead flap were objectively determined using Color Duplex-Doppler Ultrasonography. The resistance index gradually decreases, although it is considerably high at the early postoperative interval. Age, gender, and smoking do not adversely influence the blood flow in a well-designed paramedian forehead flap.

Clarithromycin resistance and 23S rRNA gene point mutations of Helicobacter pylori infection in children.

This study aims to evaluate Helicobacter pylori with clarithromycin resistant genotypes in Manisa region, Turkey. Two hundred patients, who received diagnosis of Helicobacter pylori infection histopathologically, were included. The sex, age and endoscopy indications of the patients were recorded. Polymerase chain reaction method was applied to determine the clarithromycin resistance rate and resistance genotypes at the histologic sections prepared from gastric biopsies that had been embedded in paraffin after fixation by formalin. Helicobacter pylori resistance to clarithromycin was found in 19/200 (9.5%) patients. 10/19 (52.6%) of these clarithromycin-resistant patients had A2143G mutation and 9/19 (47.4%) had A2142G mutation. A2142C mutation on 23S rRNA gene was not detected for any of the patients. Clarithromycin can be used as a first step treatment in the eradication of Helicobacter pylori for the children in our region; if the treatment fails for some patients, clarithromycin resistance, especially A2143G and A2142G mutations should be considered.

[The relationship between domestic violence and the prevalence of depressive symptoms in married women between 15 and 49 years of age in a rural area of Manisa, Turkey]. / Manisa'da Kirsal Bir Bölgedeki 15-49 Yas Evli Kadinlarda Depresif Belirti Yayginligi ve Aile Içi Siddetle Iliskisi.

OBJECTIVE: The aim of this study was to evaluate the level of depression in women of reproductive age (15-49 years) and to determine if there was a relationship between depression score, and socioeconomic variables and the presence of domestic violence. METHOD: The study group included women aged 15-49 years that lived in the Manisa/Muradiye Health Center catchment area. The minimum sample size was calculated as 224 and multistage sampling was used (random sampling plus cluster sampling). In all, 225 women enrolled in the study and were administered the BDI and a sociodemographic questionnaire that collected depressive symptomatology, domestic violence, and sociodemographic data. In addition to the descriptive data, univariate and multivariate odds ratios were obtained. Logistic regression was used for multivariate analysis. RESULTS: The prevalence of depressive symptoms (BDI score≥17) was 14.7%. In all, 32.9% of the women had experienced domestic violence. Multivariate analysis revealed that the prevalence of depressive symptoms was significantly higher among the women that had experienced domestic violence and reported having a chronic illness (p<0.05). CONCLUSION: The rates of depressive symptoms and domestic violence were quite high among the married women in this study. Preventive mental health programs should be developed and implemented in the study area.

[Level of smoking of 3rd and 4th grade students studying health and related factors: follow-up study]. / Saglik egitimi alan 3 ve 4. sinif ögrencilerinde sigara kullanimi ve etkileyen faktörler: Izlem arastirmasi.

The levels of smoking of 1st and 2nd year students at Faculty of Medicine and Manisa School of Health at Celal Bayar University were investigated in 2006-2007. This study is carried out in order to see if there is a change in the same students' level of smoking while they are in 3rd and 4th year. In addition, the study aimed to examine the factors affecting the level of use and attitudes towards the law effectuated in July 19, 2009. This is a follow-up study with 80.42% return rate. A 26-item structured questionnaire was administered. The participants filled out the questionnaires under supervision of the researchers in their classrooms. The University Institutional Review Board approved the study. The total of participants (263) of the follow-up study included 189 female and 74 male. The rate of experimenting with smoking was 49% with the mean age of 15.7 (SD= 4.01 years). The mean age of experimenting with smoking was the earliest on male students studying at faculty of medicine. The level of smoking was found to be the most on females, studying at faculty of medicine and staying at the dormitory, with smoking parents (p< 0.05). The most important reason to begin smoking was curiosity (55.2%) while bad breath and yellowing of teeth were the reasons to quit (91.7%). 83.3% of the students thought that the law will be effective on quit smoking. The level of both experimenting and use of smoking has been increased over time. It is suggested that medical students' awareness about the danger of smoking should be raised at earlier grades. In addition, lectures should be offered to students at School of Health and they should be encouraged to unite in order to fight with smoking.

Occupational asthma in welders and painters.

We aimed to investigate the frequency of occupational asthma (OA) and the factors associated with OA development in a bicycle factory, subsequently after the diagnosis of OA in three workers at the same department. Forty one welders, 23 painters and 46 controls (office workers), a total number of 110 cases were included in the study. Turkish Thoracic Society Occupational and Environmental Diseases Evaluation Questionnaire and physical examination, chest-X ray, pulmonary function tests were performed as needed. Peak expiratory flow (PEF) follow-up was done in welders and painters. Cases having symptoms related with work and >or= 20% PEF variability were diagnosed as OA. Wheezing were more frequent in welders and painters than the control group, although there wasn't a statistical significance. Dyspnea, cough and sputum production were more frequent in welders and painters with respect to controls (p< 0.05). Nine (22%) welder, 4 (18%) painter were diagnosed as OA. Working duration of welders and painters with OA (72, 156 months, respectively) were longer than the welders and painters without OA (45, 76 months, respectively), but it did not have any statistically significance. We suggest that working in welding and painting departments may cause respiratory symptoms and OA.

[The psychometric properties of the new Turkish generic health-related quality of life questionnaire for children (Kid-KINDL)]. / Cocuklar için genel amaçli saglikla ilgili yasam kalitesi ölçegi (Kid-KINDL) Türkçe sürümünün psikometrik özellikleri.

OBJECTIVE: There are few health-related quality of life (HRQOL) instruments available that have been validated for use with Turkish children. The Kid-KINDL is a generic measure of children's (8-12 years) HRQOL, which contains 24 categorical items that assess 6 dimensions (physical well-being, emotional well-being, self-esteem, family, friends, and school). The Kid-KINDL is available in many languages. Following an elaborate translation procedure and cognitive focus group interviews, the Kid-KINDL was adopted into Turkish. This paper describes the psychometric properties of the new Turkish Kid-KINDL. METHODS: In total, 1918 children aged 8-12 years at a school in Manisa completed the Kid-KINDL. A confirmatory approach was used for validity and reliability analysis. Using the Multi-trait/Multi-item analysis program (MAP) item-internal consistency and item-discriminant validity were calculated to confirm the instrument's structure. Likert scaling assumptions were tested and confirmatory factor analysis (CFA) was applied as well. After modification of 2 unsatisfactory items the Kid-KINDL was administered to a different group of 84 randomly selected children and the analyses were repeated. RESULTS: Cronbach's alpha was 0.35-0.78 before and 0.54-0.78 after the scales was modified. MAP-scaling success was 60%-100% before and 90%-100% after the modification. CFA confirmed the Kid-KINDL structure for the original version (RMSEA = 0.077) was less than the modified version (RMSEA = 0.059), although for the latter the sample was rather small. Floor effects were negligible, and ceiling effects reached 19%. CONCLUSION: The results indicate that the Turkish Kid-KINDL was a reliable and factorially valid assessment of the children's HRQOL. The modifications made to the 2 unsatisfactory items increased the psychometric quality of the scale.

[The prevalence of low back pain and its relationship with household jobs and other factors in a group of women in a rural area in Manisa]. / Manisa'da kirsal bir bölgede kadinlarda bel agrisi sikligi; ev isleri ve diger faktörlerle iliskisi.

The aims of this cross-sectional study were to determine the prevalence of low back pain and to evaluate the effects of household jobs on low back pain in women living in a rural setting in Manisa. Study population is consisted of 302 women and cluster sampling is performed according to percentage of health center district populations. Participation ratio of this study was 89.1%. Univariete and multivariete risk approach in 95% confidence interval and t test were performed in data analysis. Brief Disability Questionnaire was applied to the study group. Life time and point prevalence of low back pain were determined 79.2% and 34.9% of the study group. Low back pain risk in 95 % CI was higher in wrong posture during ironing, heavy load lifting, overweight/obesity and disability 2.2 (1.1- 4.5), 4.5 (2.1-9.2), 3.8 (1.7-8.3) and 9.2 (4.3-19.7) times respectively. For preventive health measures it is necessary to apply ergonomic working conditions and to give appropriate postural habits to women.
