Background Splenectomy has been associated with an increasedsusceptibility to infection. Overwhelming postspelenectomy infec-tion (OPSI) can lead to high mortality. Decreased IgM and tuftsinconcentration on splenectomized patients seems to play a role ininfection’s susceptibility. Many studies have been performed todetermine the risk factors of infection in thalassemic patients.Objective To find out morbidity patterns and risk factors for pre-dicting the likelihood of infection in splenectomized thalassemicpatients.Methods A retrospective cross sectional study was conducted onconfirmed thalassemic children who came to Department of ChildHealth, Cipto Mangunkusumo Hospital within the period of 1973-2003. Splenectomized patients were categorized as cases groupand non-splenectomized patients as control group. Risk factors fordevelopment of common cold and diarrhea were analyzed usingchi-square test with level of significance <0.05.Results A total of 300 thalassemic patients, 100 of them were sple-nectomized, were enrolled in this study. The 15-year-age group orabove is the most common group underwent splenectomy (35%).Common cold is the most common mild infection in both splenec-tomized group (75%) and non-splenectomized (71%). A significantassociation was found between the risk of infection and splenec-tomy in thalassemic patients (OR=3.8;CI=2.2;6.62; P=0.000). As-sociation between time after splenectomy and frequency of com-mon cold in thalassemia was significant (OR=2.85;CI=1.16;7.14;P=0.011). Severe infection and acute diarrhea were considerednot significantly different between the two groups.Conclusion Splenectomy in thalassemia can increase the sus-ceptibility of non-transfusion-transmitted mild infection. Furtherstudy is needed to elaborate this finding

CONTEXT AND OBJECTIVE:There have been few studies on the risk factors for subgroups of stuttering. The aim of this study was to characterize the risk factors for developmental familial stuttering among boys who stutter and who do not stutter, such as disfluency types, associated quality and communication factors, emotional and physical stress, familial attitudes and personal reactions.DESIGN AND SETTING:Analytical cross-sectional study with a control group, performed at the Fluency Studies Laboratory of the Department of Speech and Hearing Disorders of a public university.METHODS: The parents of 40 age-matched stuttering and non-stuttering boys took part in this study. The participants were divided into two groups: stuttering children (SC) and non-stuttering children (NSC), with ages between 6 years 0 months and 11 years 11 months. Initially, all of the participants underwent a fluency assessment and then data were gathered using the Protocol for the Risk of Developmental Stuttering.RESULTS:There were no differences in the physical stress distribution factors and personal reactions between the groups. Inappropriate familial attitudes were presented by 95% of the SC and 30% of the NSC. Four risk factors analyzed were not shown by the NSC, namely stuttering-like disfluency, quality factors, physical stress and emotional stresses.CONCLUSIONS:The findings suggest that the presence of stuttering-like disfluency, associated quality and communication factors, emotional stress and inappropriate family attitudes are important risk factors for familial developmental stuttering among boys.

The prevalence of soil transmitted helminths (STH) is closely related to the defecation facilities for rural communities, such as: the habit of defecating openly on the ground, in gardens and using open latrines in rivers. The aim of this study was to determine the effect of environmental sanitation risk factors on the prevalence of STH infection. This study was included in an analytical epidemiological study at two locations, using a cross sectional study as the research design. The location were Sri Kembang Village, Bukit Village, which is included in Betung District, Banyuasin Regency, and South Sumatra, Indonesia for 30 days. There were 252 students as the research sample. Data analysis showed that the prevalence of T. trichiura was higher in Sri Kembang State Primary School Number 1 with mild to very severe infection degrees. The intensity of A. lumbricoides infection in Bukit State Primary School Number 1 got a higher prevalence than Sri Kembang. Open defecation, gardens or open latrines, and types of houses with dirt floors indicate environmental sanitation factors that are sufficient to support the prevalence of STH. For further research, it is recommended to examine socio-economic risk factors.

Introduction: Sleep disturbances and anxiety are the first physical reflections observed in healthcare professionals. The aim was to reveal the sleep characteristics and moods of healthcare professionals during the pandemic for making improvements and provide support. Methods: This study is observational and cross-sectional study and was carried out in a training and research hospital in Kirsehir, Turkey. A total of 48 nurses, 25 doctors, 37 assistant health personnel, 12 security guards, and 25 medical secretaries were included, of which 147 were healthcare professionals and 50 were not healthcare professionals (control group). Three questionnaires were used; two to measure sleep, one to measure stress. The volunteer participants were administered face-to-face Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale, and Beck Stress Scale (BSS) simultaneously and scored individually. These scores were evaluated separately for demographic characteristics and their association with occupational groups. Results: A total of 197 people were included in the study, of which 147 were healthcare professionals, and 50 were not healthcare professionals (control group). The average age of the participants was 34.15 ± 9.18 years. The participants’ average PSQI (6.25 ± 3.24), ESS (7.46 ± 3.16), and BSS (11.26 ± 4.65) were calculated. The difference between the BSS (p < 0.01) and PSQI (p < 0.05) values of women and men was statistically significant. BSS and PSQI values were low in security guards. However, these values were high in nurses. The occupational experience of the participants in all three scales was not statistically significant. It was higher in the control group than the healthcare professional group. However, these differences between the groups were not statistically significant. Discussion and Conclusion: In the COVID-19 pandemic, there was no difference in sleep and anxiety characteristics between health workers and non-health workers and the most common group of healthcare professionals with anxiety, sleep disorders was nurses. Based on the results, women and nurses between the ages of 31-35 should be given priority in support of healthcare professionals.

Purpose. To explore risk factors of vulvovaginal candidiasis (VVC) among women of reproductive age in Xi’an district and then to offer reference for clinical prevention and treatment of VVC. Methods. Patients from the outpatient department of gynecology and obstetrics in the First Affiliated Hospital of Xi’an Jiaotong University from June 2016 to May 2017 were recruited strictly according to the inclusion and exclusion criteria. Participants diagnosed as simple VVC were assigned to the case group, while women who underwent routine gynecological examination and had normal vaginal microflora were assigned to the control group. Then we conducted a questionnaire survey of the two groups and used the logistic regression model to explore the related risk factors of VVC. Results. In the present study, ninety-seven cases were sample VVC patients and eighty-seven cases were healthy women. This cross-sectional study showed that occasionally or never drinking sweet drinks (odds ratio [OR] =0.161, 95% confidence interval [CI] =0.056-0.462, P=0.001), occasionally or never eating sweet foods (OR=0.158, 95%CI=0.054-0.460, P=0.001), and the use of condom (OR=0.265, 95%CI=0.243-0.526, P=0.001) were regarded as protective factors for VVC. In addition, sedentary life style (OR=7.876, 95%CI=1.818-34.109, P=0.006), frequently wearing tights (OR=6.613, 95%CI=1.369-27.751, P=0.018), frequent intravaginal douching (OR=3.493, 95%CI=1.379-8.847, P=0.008), having the first sexual encounter when under 20 years old (OR=2.364, 95%CI=1.181-7.758, P=0.006), the number of sexual partners being over two (OR=3.222, 95%CI=1.042-9.960, P=0.042), history of curettage (OR=3.471, 95%CI=1.317-9.148, P=0.012), history of vaginitis (OR=8.999, 95%CI=2.816-28.760, P<0.001), and not cleaning the vulva before or after sexual encounters (OR=13.684, 95%CI=2.843-65.874, P=0.001) were considered to be risk factors of VVC. Conclusion. In conclusion, risk factors of VVC are various, involving ages, hygienic habits, disease history, and other aspects.

There are insufficient data on the prevalence of Trichomonas vaginalis infection in pregnant women in South Africa. The present study aims to determine the prevalence of T. vaginalis (TV) in pregnant women and identify the risk factors associated with this infection in pregnancy. This was a cross-sectional study which included 362 pregnant women attending the antenatal clinic at the King Edward VIII Hospital in Durban, South Africa. A self-collected vaginal swab was provided by the enrolled women for laboratory diagnosis by real-time polymerase chain reaction. The protozoan load was determined as the logarithm of gene copies per milliliter. The prevalence of TV infection was 12.9% and 59.6% of the women who tested positive were asymptomatic ( p =  0.011). Women who presented with abnormal vaginal discharge had a 4.6 times likelihood of testing positive for TV infection (odds ratio 4.62; 95% confidence interval 1.83 to 11.70; p =  0.001). TV infection was high amongst pregnant women. Therefore, routine testing for this sexually transmitted infection is encouraged for proper management.

Abstract Objectives To establish the prevalence of back pain in rowers at different competition levels and rowing typologies compared with a non-rowing control group; to determine different time periods, the location on the spine, and different pain characteristics. Additionally to evaluated different risk factors that might be responsible for back pain. Methods A standardized and validated online back pain questionnaire was sent to elite and non-elite rowers of different rowing typologies, and a physically active non-rowing control group. Results Responses from 156 rowers (104 elite and 52 non-elite/ 49 scull and 76 sweep rowers) and 166 controls were received. Back pain prevalence and severity was significantly higher among rowers compared with controls, and among scull compared with sweep rowers. The lower back was the main location of back pain in rowers of all competition levels and typologies, and in controls. Age, sex, and training volume influenced the prevalence of back pain. Rowing kinematics, strength, and ergometer training were the main associated risk factors for back pain in rowers. Conclusions Back pain in different spinal locations is a common complaint in rowers of different typologies and competition levels. Rowing kinematics, strength, and ergometer training are the main associated risk factors for developing back pain in rowers. Thus, the spinal load due to rowing kinematics and different types of training should be investigated in future studies. Additionally, training should be monitored by experienced coaches to prevent back pain due to technical mistakes or too-heavy loads.

Nulliparous Women

CONTEXT AND OBJECTIVE: Preeclampsia is a gestational disease that occurs mainly among nulliparous women after the 20th week of gestation, and frequently close to delivery. The effects of preeclampsia on women's blood pressure over the long term are still controversial. Patients with recurrent preeclampsia or preeclampsia in the early stages of pregnancy appear to present higher risk of hypertension. The aim of this study was to determine the risk factors for cardiovascular disease among women with preeclampsia 10 years earlier. DESIGN AND SETTING: Cross-sectional study at Hospital de Clínicas de Porto Alegre (HCPA). METHODS: Forty women with preeclampsia and 14 normotensive pregnant women followed up 10 or more years earlier at HCPA underwent clinical and laboratory examinations. Spearman's correlation coefficient was used to correlate body mass index (BMI) and systolic and diastolic pressures. The risk of developing hypertension was measured using the chi-square test. P < 0.05 was considered significant. RESULTS: The patients with preeclampsia 10 or more years earlier had significantly higher diastolic blood pressure (P = 0.047), BMI (P = 0.019) and abdominal circumference (P = 0.026). They presented positive correlations between BMI and diastolic blood pressure (0.341; P = 0.031) and between BMI and systolic blood pressure (0.407; P = 0.009). CONCLUSION: The patients with preeclampsia 10 or more years earlier had significantly higher diastolic blood pressure, BMI and abdominal circumference than did the control group. This emphasizes the importance of long-term follow-up assessment for cardiovascular risk factors among patients with preeclampsia.

Background: Lipids are known to accumulate abnormally in the alveoli and circulate during pulmonary alveolar proteinosis (PAP). However, the relationship between lipid ratios and PAP is not clear. In this study, we investigated the lipid ratios in PAP patients and explored the relationships between lipid ratios and the severity of PAP.Methods: A total of 122 PAP patients were diagnosed and divided the mild- moderate PAP group (n = 61) and the severe PAP group (n = 61) according to the value of disease severity score (DSS). One hundred thirty healthy volunteers were classified as the control group. Routine blood examination and pulmonary function tests were performed and lipid profile were measured.Results: Compared with the control group, patients with PAP had significantly higher TG, TC/HDL-C, TG/HDL-C, and non-HDL-C, while lower HDL-C (all P &lt; 0.05). Patients with the severe PAP had higher TC, TG, LDL-C, TC/HDL-C, and non-HDL-C, while lower HDL-C than patients with the mild- moderate PAP (all P &lt; 0.05). Binary logistic regression analysis indicated that TC/HDL-C (OR = 2.322, 95% CI 1.621–3.713, P = 0.024) and non-HDL-C (OR = 1.797, 95% CI 1.239–3.109, P = 0.036) were all significantly correlated with the severity of PAP after adjustment for other risk factors. The AUC value of TC/HDL-C for predicting the severity of PAP was larger than that of non-HDL-C. The AUROC for TC/HDL-C was 0.741 (0.654–0.828), and the optimal cut-off point for TC/HDL-C was 5.05 (sensitivity: 73.6%, specificity: 68.1%).Conclusions: Lipid ratios, including TC-HDL-C and non-HDL-C, were independent risk factors for the severity of PAP. TC/HDL-C is a promising biomarker for the severity of PAP.

Artery Disease

CONTEXT AND OBJECTIVE: Atherosclerotic disease is the leading cause of death in Brazil. It is a complex disease and its prevention involves identification and control of risk factors. Moderately increased plasma homocysteine concentration (hyperhomocysteinemia) has been considered to be a risk factor for several vascular diseases. Mutations in the methylenetetrahydrofolate reductase (MTHFR) enzyme, which is involved in homocysteine metabolism, have been investigated as potential vascular disease risk factors. G1793A polymorphism was described in 2002 and there are few studies analyzing its involvement in diseases. The objective of this study was to investigate the prevalence of G1793A polymorphism in subjects with early coronary artery disease (CAD). DESIGN AND SETTING: Cross-sectional study with control group conducted at a private cardiology clinic and a molecular biology laboratory (Universidade do Vale do Itajaí). METHODS: We studied 74 early-onset CAD+ patients and 40 CAD- individuals with normal angiography results. DNA was extracted from blood samples. Molecular data were obtained via PCR/RFLP and agarose gel electrophoresis. RESULTS: The occurrence of G1793A heterozygotes was similar in the control (5%) and test (6.25%) groups, thus showing that in the population studied there was no correlation between the marker and occurrences of early CAD. There was also no association between the polymorphism and the risk factors for atherosclerosis. CONCLUSIONS: The frequency of the 1793A allele in the test group (3.4%) was similar to what was found in the control individuals (2.5%). There was no correlation between G1793A polymorphism and occurrences of early CAD in this population.

Objectives: This paper aims to develop and describe a method for combining, comparing, and maximizing the statistical power of two longitudinal studies of risk factors for cardiovascular disease that did not have identical data collection methodologies. Methods: Subjects from a 1986 cross-sectional study (n= 180) were pair-matched with subjects of corresponding gender and age (+ 5 years) from a 1990 cross-sectional study. The methodology is described and results are calculated for various measures of cardiovascular risk or risk factors (e.g. cholesterol, Finnish Risk Score). Results: Box's test of equality and symmetry of covariance matrices gave chi-square values of 223.8 and 710.0 for two cardiovascular risk factors (cholesterol and cardiac risk score, respectively); these values were highly significant (p=0.0001). For the North Karelia Risk Score, repeated measures ANOVA revealed a borderline significant interaction for treatment by time (p=0.054) and a significant interaction for treatment by time by country (p=0.035). These probabilities compared favorably with a randomized blocks model. Conclusions: Creation of a synthetic longitudinal control group resulted in a statistically valid ANOVA model that increased the statistical power of the study.
