Postmenopausal women's cognitive function and performance of virtual reality tasks.

OBJECTIVE: This study aimed to assess whether prior knowledge of computer use determines performance of virtual reality tasks by postmenopausal women and whether menopausal symptoms, sociodemographic factors, lifestyle and cognition modify or interfere with their performance. METHOD: This cross-sectional study included 152 postmenopausal women divided into two groups: computer users and non-users. Age, ethnicity, time of menopause, menopausal symptoms, female health status, level of physical activity and cognitive function were considered. The participants played a virtual reality game and were assessed for hits, errors, omissions and game time. The Mann-Whitney, chi-square and Fisher exact tests and multivariate linear regression analysis were used. RESULTS: Postmenopausal computer users play virtual reality games (p = 0.005) better than postmenopausal non-users of computers. Vasomotor symptoms were high in women who used computers compared to those who did not (p = 0.006). Multivariate linear regression analysis found that the best-fitting predictors for the number of hits - that is, age (p = 0.039), Mini-Mental State Examination score (p = 0.006) and the headache symptom (p = 0.021) - influence the performance of virtual reality tasks. CONCLUSION: Computer users performed virtual reality tasks better than non-users. Headache and age but not vasomotor symptoms negatively affected the postmenopausal women's performance.

Use of interventions involving virtual reality tasks during the climacteric: a systematic review.

Technological advances have been impacting health care worldwide. Our study aimed to research the literature systematically to determine the impact of technological treatments versus conventional treatments on the quality of life of climacteric women. The study was registered on PROSPERO (CRD42021241638). We searched seven databases, including PRISMA, using mesh terms. After screening for eligibility, we selected five clinical trials, and applying the snowball technique we were able to include four more articles, totaling nine articles that used technology-based interventions (virtual reality games) during the climacteric. The total study population consisted of 298 climacteric women. Two studies evaluated a technology-based treatment for pelvic floor, one for urinary incontinence symptoms, three for postural balance, one for cardiorespiratory capacity, one for osteoporosis and one study for lower back pain. The studies showed that the technological treatments improved pelvic floor strength, balance, cardiorespiratory fitness and bone mineral density when compared to conventional treatments. Improvement was linked to adherence to training and a high level of satisfaction during the training sessions. Technology-based treatments appear to be a viable alternative to conventional treatments in improving the quality of health, with benefits for the cardiovascular, genitourinary and skeletal systems, and ultimately for the overall quality of life.

Dietary intake and menopausal symptoms in postmenopausal women: a systematic review.

Despite literature pointing to a relation between dietary intake and menopausal symptoms, most studies have evaluated either only supplements or only specific nutrients or foods. Therefore, this study aimed to provide a systematic review of the literature regarding the association between dietary intake and menopausal symptoms in postmenopausal women. A systematic search was conducted across PubMed/Medline, Web of Science, Scopus, and Embase to identify studies published between 2009 and 2019. We identified 3828 studies; after screening, 73 studies were reviewed and 19 of these investigated nutrient and food intake and eating patterns associated with the intensity of menopausal symptoms. Studies evaluating diet quality or dietary patterns showed an association between lower intensity of psychological symptoms, sleep disorders, and vasomotor, urogenital, and somatic symptoms and higher consumption of vegetables, whole grains, and unprocessed foods. Also, the intensity of these symptoms is associated with high-processed foods, saturated fats, and sugars. Regarding nutrient and/or specific food, the studies indicated an association between caffeine intake and type of fat intake and the intensity of menopausal symptoms. Dietary intake was found to be associated with the severity of menopausal symptoms; however, evidence for the association between dietary intake and menopausal symptoms is inconsistent and inconclusive, and is provided by a small number of studies.

Inappropriate Postural Habits of High School Students from the Municipality of Ceres, Brazil.

This study aims to evaluate the prevalence of inappropriate postural habits in students. 827 Brazilian students aged 14 to 19 were evaluated with a self-administered questionnaire. A high prevalence of (>90%) inappropriate habits in sitting postures (on a chair, to write, and at a computer) and picking up an object off the floor was observed, suggesting the need to develop preventive programs.

Fatal anthrax infection in a heroin user from southern Germany, June 2012.

Blood cultures from a heroin user who died in June 2012, a few hours after hospital admission, due to acute septic disease, revealed the presence of Bacillus anthracis. This report describes the extended diagnosis by MALDI-TOF and real-time PCR and rapid confirmation of the anthrax infection through reference laboratories. Physicians and diagnostic laboratories were informed and alerted efficiently through the reporting channels of German public health institutions, which is essential for the prevention of further cases.

CO2 laser-assisted treatment of a giant pyogenic granuloma of the gingiva.

BACKGROUND: Pyogenic granuloma (PG) may develop in the oral cavity of pregnant women. The periodontal treatment outcomes during and after pregnancy are described. METHODS: A 34-year-old woman in the 39th week of pregnancy presented for surgical treatment with a mass on the lingual mandibular gingiva. She had been surgically treated alio loco in the 37th week, but this failed. The patient was reassured and an individual oral hygiene programme was initiated in our department. The tumour was about 20 mm in diameter. A CO(2) laser-assisted surgical excision was performed 4 weeks after delivery. The lesion was analysed histopathologically using a von Willebrand Factor immunoreactivity staining. The highly vascularized tissue with a dense inflammatory infiltrate was in accordance with the diagnosis of a PG. RESULTS: The initial wound healing was uneventful. A 12-month follow-up revealed no recurrence of the mass and healthy periodontal tissues. CONCLUSION: This report describes an oral complication during pregnancy for which surgical excision of a PG after delivery seemed the best treatment. It is possible that gender-specific periodontal disease risk factors contributed to the development of the lesion. This is another reason why pregnant women should be encouraged to be assessed by oral health professionals before late pregnancy.

[Early gastric cancer--or not]. / Magenfrühkarzinom oder doch nicht?

A 46-year old female patient presented with non-specific epigastric discomfort that had been present for 6 months. Endoscopic work-up showed a small gastric polyp and biopsy samples revealed adenocarcinoma. There was no evidence of metastatic disease or penetration of the muscle layer on endosonography, rating the tumor as early gastric cancer. Endoscopic submucosal dissection was unsuccessful due to bleeding complications and the patient was treated with subtotal gastrectomy. Surprisingly, the final histological diagnosis revealed a highly differentiated neuroendocrine tumor and the initial diagnosis had to be revised.

Efficacy of praziquantel treatment of schistosomiasis in a non-endemic country: a follow-up of parasitological, clinical and immunological parameters.

Schistosomiasis patients were immigrants to Czechoslovakia from Angola and Yemen. Most of them had light or moderate infections and felt subjectively healthy. They received treatment with praziquantel (two doses with a total of 40 mg/kg) and were followed up for several years. In nine of 13 patients, Schistosoma haematobium or S. mansoni eggs with undamaged miracidia were detected in biopsies from the bladder or the rectum one year or later after treatment. Granulomatous reactions in the rectum and bladder lesions of stage 1 including thickened bladder walls persisted in most of the patients. Antibody levels against adult S. mansoni worm antigen remained elevated for at least two years after therapy in some patients and declined in others. Among the nine patients, for whom pre- and post-treatment sera were available, the changes in relative levels of antibodies did not strictly correlate with the continued presence of schistosome eggs in, or their absence from, biopsies. We discuss the results obtained with sensitive diagnostic techniques in the absence of subjectively perceived disease.

Entamoeba histolytica--the virulence of imported strains.

We tested the virulence of 15 strains of Entamoeba histolytica, imported to Czechoslovakia, by intracaecal inoculation of laboratory rats. According to the scoring system of Neal, none of the 15 strains possessed the virulence index greater than 2. This indicates that all the organisms tested should be classified as avirulent. However, it should be noted that all the strains produced infection of the caecum and thus should be considered infective for rat. For 7 strains, isoenzyme patterns were determined for PGM, HK and ME. One imported strain, obtained from student from Congo, demonstrated isoenzyme pattern for PGM and HK indicated that the strain was virulent. This organisms had the index of virulence 1.8 (avirulent) in animal experiment; it was isolated from cysts of clinically asymptomatic patient. Examination of the rectal mucosa of the donor of the strain indicated typical chronic catarrhal proctitis of mild degree. Examination of the patient's serum demonstrated the presence of anti E. histolytica antibodies by CIEP, while the ELISA test was negative. Twenty-one cyst carriers were examined by rectoscopy. Pathologic changes were observed in 20 of these, as follows: altered vascular structure (13X), roughened mucosa (12X), mucosal reddening (10X), decreased glistening (7X), mucus in mucosa (5X), inflammatory pseudopolypes (2X), ulcers (2X), enanthema (1X). Histological biopsies were obtained in 15 cases. One was considered normal. Remaining 14 biopsies exhibited following morphological changes: increased mucus secretion (8X), edema (7X), lymphocytic and plasmocytic infiltration (6X), lymphocytic and plasmocytic infiltration in addition to the presence of eosinophilic granulocytes (6X), presence of mucophages (5X), haemorrhages (4X), increased vascularity (3X), lymphocytic and plasmocytic infiltration with presence of extremely abundant eosinophilic granulocytes (1X), erosive-ulcerative changes of mucosa (1X). The changes observed indicated chronic catarrhal proctitis with expression to greater or less degree of signs of chronic catarrhal inflammation.

Contribution to the question of relationships between Enterobius vermicularis (L.) and inflammatory processes in the appendix.

We evaluated a bioptic material of appendices from the hospital in Ceské Budejovice, obtained from 1977-1981. Of these, 2173 appendices were removed as cases of a clinical appendicitis, 788 for preventive reasons. In the cases of a clinical appendicitis with the incidence of pin worms in the appendix, the histological picture displayed significantly more chronical, inflammatory changes than in acute cases (test chi 2), while in cases of a clinical appendicitis without the presence of pin worms, we found more acute than chronical forms of inflammations. Our results are supported also by an analysis of preventively removed appendices, where again more chronical, inflammatory changes were found in appendices with pin worms.

The effects of sexual status on threat, attack and subordinate behaviors of papio monkeys.

Performance of perception of threat, attack, and subordinate behaviors at different phases of the perineal cycle in 24 female group papio monkeys (super-species Papio cynocephalus) was compared. The subjects ranged in age from 36 to 42 months at the inception of the study and were observed over a 2-year period. Females performed significantly fewer threat and attack behaviors during the swollen phase of the perineal cycle and showed no significant differences in the reception of the three behavioral measures. The reduction in the performance of aggression that occurs during the swollen phase of the perineal cycle reflects a shift in the focus of interactions during consortship to a single male.
