A multicenter survey on toxoplasmosis knowledge among pregnant women in Poland (the TOWER study).

BACKGROUND: The seroprevalence of Toxoplasma gondii ranges widely in different areas of the world and different populations. Although toxoplasmosis is typically benign and asymptomatic, it induces major complications in immunocompromised individuals and during pregnancy. Prevention of maternal primary infection constitutes the major tool for avoiding congenital T. gondii infections and toxoplasmosis complications. The preventive measures depend on the women's knowledge about toxoplasmosis. The aim of the study was to assess the knowledge on toxoplasmosis among pregnant women in Poland. METHODS: The study was conducted between October 2016 and January 2017 in 3 Polish cities. During a visit in a hospital outpatient clinic, pregnant women aged > 16 years fulfilled a previously validated questionnaire. The questions concerned personal data (age, parity, educational level, place of residence), toxoplasmosis knowledge (etiology, routes of transmission, symptoms, sequelae), and sources consulted to collect information. RESULTS: Overall, 465 pregnant women participated in the survey; 439 (94.4%) were aware of toxoplasmosis. Toxoplasmosis was perceived as a zoonotic disease by 77.4%, as a parasitic disease by 41.7%, as a disease transmitted through poor hand hygiene by 8.6%, as a childhood illness by 4%, and as a congenital disease by 0.4%. Regarding the transmission route, 84.5% of women pointed at a domestic cat, 46.7% at eating raw or undercooked meat. The total of 84.3% did not know toxoplasmosis symptoms, and 12.0% stated that they did not present the symptoms. In multivariate analysis, younger age (OR, 2.74; 95% CI, 1.67-4.49; p <  0.001), city residence (OR, 13.45; 95% CI, 3.12-57.89; p <  0.003), and higher education level (OR, 6.81; 95% CI, 3.69-12.59; p <  0.001) were significantly associated with better knowledge of toxoplasmosis, and the number of children (OR, 0.32; 95% CI, 0.22-0.48; p <  0.001) - with higher knowledge of the symptoms. CONCLUSIONS: Among pregnant women in Poland, the basic knowledge on toxoplasmosis is very high (94.4%). Younger age, city residence, higher education level, and the number of children turned out significantly associated with better knowledge of T. gondii and toxoplasmosis symptoms.

Effects of the menstrual cycle phases on the tilt testing results in vasovagal patients.

PURPOSE: The aim of the study was to assess the distribution of positive tilt testing (TT) throughout the menstrual cycle and to determine if the phase of menstrual cycle contributes to the duration of the loss of consciousness. METHODS: TT results of 183 premenopausal women, aged 29.5 ± 9.8 years, were studied. The menstrual cycle was divided into four phases based on the first day of the last menstrual bleeding: perimenstrual (M), preovulatory (F), periovulatory (O) and postovulatory (L). RESULTS: Positive TT results were equally distributed. In patients with TT in O phase, the highest percentage of NTG provocation was needed. Patients in L phase had significantly lower incidence of cardioinhibitory reaction. The longest duration of loss of consciousness was in the M phase. Multiple regression analysis revealed that the duration of loss of consciousness during positive TT was significantly associated with higher number of syncopal events, TT performed in M phase and lower heart rate at TT termination. Cardiodepressive type of neurocardiogenic reaction was more frequent during M and O phase than during L phase. CONCLUSIONS: The distribution of positive TT results as well as syncope and presyncope does not differ throughout the menstrual cycle. Diagnostic TT in premenopausal women with unexplained syncope could be performed irrespective of the phase of menstrual cycle. TT has similar sensitivity throughout the menstrual cycle. During the postovulatory phase, cardioinhibitory reaction is less frequent than in M and O phases. The duration of loss of consciousness is longer during the M phase of the menstrual cycle independently of the higher syncope number and lower heart rate at TT termination.

The risk for syncope and presyncope during surgery in surgeons and nurses.

BACKGROUND: Surgeons and nurses are exposed to orthostatic stress. AIMS: To assess the lifetime incidence of syncopal and presyncopal events during surgery in operation room staff and reveal the predicting factors. METHODS AND RESULTS: The study included 317 subjects (161 F, 156 M) aged 43.9 ± 9.6; 216 surgeons and 101 instrumenters. The study included filling of an anonymous questionnaire on the syncope and presyncope history. RESULTS: At least one syncopal event during operation was reported by 4.7% and presyncope by 14.8% of the studied population. All but one subject reported prodromal symptoms before syncope. In the medical history, syncope outside the operating room was reported by 11% of the studied group. Syncope and presyncope during operation was related to syncope in the medical history outside the operation room, respectively: odds ratio (OR) 20.2 95% confidence interval (CI): 2.0-70.5 and OR 10.8; CI: 5.0-23.4 and to presyncope in the medical history, respectively: OR 23.5; CI: 7.4-74.4 OR 8.9; CI: 3.6-11.2 (P < 0.001). CONCLUSIONS: (1) Syncope and presyncope may occur during surgery in the staff of the operating room. (2) Syncope in the operating room is usually preceded by prodromal symptoms and has vasovagal origin. (3) Both lower then expected occurrence of syncope in the operating room staff and absence of any difference between genders in this regard indicate preselection in the process of choosing profession and specialization. (4) Syncope and presyncope outside the operating room in medical history increases the risk of syncope and presyncope inside the operation room.

Inhibin B and FSH as markers of Sertoli cell function in impaired spermatogenesis.

INTRODUCTION: The relationships between inhibin B, FSH and sperm count have never been fully elucidated. Our aim was to search for associations between serum concentrations of inhibin B/FSH and the impairment of spermatogenesis. MATERIAL AND METHODS: In an observational study, we compared sperm count, serum levels of inhibin B and FSH in men with oligozoospermia (n = 46) and in normozoospermic, fertile controls (n = 38). RESULTS: Concentration of FSH was 10.27 ± 11.24 IU/L in the oligozoospermic and 3.84 ± 2.76 IU/L in the normospermic group (p 〈 0.01). Although the concentration of inhibin B was higher in the oligozoospermic group (424 ± 443 v. 297 ± 219 pg/mL), the difference was statistically insignificant. CONCLUSIONS: Our results suggest that there is a tendency toward increased serum inhibin B levels in subjects with altered sperm count and increased serum FSH.
