Introduction: Aerobic vaginitis (AV) is a type of vaginal infection that occurs at the reproductive age of women. In this study, we aimed to study the possible anti-AV therapeutic effects of silver nanoparticles (AgNPs) and L-carnitine (LC) in the mouse model. Methods: AV model was established by intra-vaginal inoculation of 108 CFU/mL Staphylococcus aureus and Escherichia coli (1:1) in adult NMRI mice. Susceptibilities of the bacteria were examined against AgNPs by inhibitory concentration (IC-50 and IC-90) and minimum biofilm inhibitory concentration (MBIC- 90) methods. The regimens therapy was intra-vaginal inoculation of AgNPs at MBIC- 90 and a daily injection of 250 mg/kg LC for two weeks. Mice were classified into healthy (control) and AV groups and then treated by LC, AgNPs, and AgNPs + LC. The vaginal smears were taken daily and tissue sections were prepared using the hematoxylin and eosin (H & E) method. Results: Minimum inhibitory concentrations (MICs) of AgNPs for E. coli, S. aureus, and their mixture were 250, 125, and 500 ppm, and their MBIC-90% were 500, 250, and 1000 ppm, respectively. The estrus cycle of mice treated with co-administration of AgNPs and LC was similar to the control group (P < 0.05). The results of histology also showed that infected mice were treated with AgNPs and LC, simultaneously. Conclusion: Single bacteria are more sensitive than their mixed model to these NPs. Co-administration of AgNPs as an antibacterial agent and LC as an antioxidant agent can treat AV in the infected mice.

The present study was performed to investigate the contribution of typical and atypical enteropathogenic Escherichia coli (EPEC) as a cause of infectious diarrhoea among children less than 10 years old in Iran. During the summer months, 247 specimens from children with diarrhoea and 1108 from asymptomatic children were analysed for the presence of EPEC and other bacterial pathogens. Potential enteric pathogens were identified in 140 cases of children with diarrhoea (56.7 %). EPEC was the most frequently identified agent (111 cases), followed by Shiga toxin-producing E. coli (13), Shigella (9), Salmonella (6) and Aeromonas sp. (1). EPEC isolates were examined for the presence of eaeA, bfpA and stx genes by PCR. EPEC isolates were classified as typical (eaeA + bfpA +) or atypical (eaeA + bfpA −). Typical EPEC was diagnosed in 35 cases (11.8 %), compared with 8 (0.4 %) in the asymptomatic group (P<0.05). Atypical EPEC strains were isolated from 23 cases (9.3 %), compared with 13 (1.2 %) of the healthy control group (P<0.05). In conclusion, the data suggest that typical and atypical EPEC are an important cause of diarrhoea in Iranian children.

Abstract Background Autoimmune thyroid disease in women is associated with subfertility and early pregnancy loss, and patients with primary ovarian insufficiency have a high prevalence of thyroid autoimmune disorders. The aim of this study was to investigate the association between Hashimoto thyroiditis and ovarian reserve. Methods Levels of serum thyroid stimulating hormones, thyroid autoantibodies, and anti-Mullerian hormone (AMH) were measured in women with Hashimoto thyroiditis (HT) and a healthy control group between 2018 and 2019. Result Evaluation was made of 108 premenopausal women with Hashimoto thyroiditis. A control group was formed of 172 healthy female subjects with normal anti-thyroid antibody levels and thyroid function. Serum AMH levels were determined to be significantly lower in the HT group compared to the control group. Conclusion Ovarian reserve evaluated by serum AMH concentration is affected by thyroid autoimmunity independently of anti-thyroid antibodies type or titers.

The effects of both garlic (Allium sativum) and onion (Allium cepa) on some biochemical parameters in Schistosoma mansoni infected mice individually and mixed either with or without the currently used drug, praziquantel (PZQ) were investigated. These involved some immunological parameters, namely IgM, IgG, interleukins 2 and 6 (IL-2 and 6) and tumor necrosis factor (TNF-α), some antioxidant enzymes [catalase, superoxide dismutase (SOD) and glutathione peroxidase (GPX)]. In addition, parasitological and histopathological investigations were performed. No changes were observed in the normal control mice treated with dry extract of onion or garlic, individually or mixed, with or without PZQ, compared to the normal healthy control group. Infection with S. mansoni showed an increase in IgG, IgM, IL-2, IL-6, TNF-α and catalase enzyme, accompanied with a decrease in GPX and SOD antioxidant enzyme activities. Remarkable amelioration was noticed in the levels of all the measured parameters in S. mansoni infected mice after administration of the studied extracts. Moreover a significant reduction in worm burden, hepatic and intestinal eggs and oogram count was noticed which was reflected in normalization of liver architecture.

AbstractThe developmental course of daily functioning prior to first psychosis-onset remains poorly understood. This study explored age-related periods of change in social and role functioning. The longitudinal study included youth (aged 12–23, mean follow-up years = 1.19) at clinical high risk (CHR) for psychosis (converters [CHR-C], n = 83; nonconverters [CHR-NC], n = 275) and a healthy control group (n = 164). Mixed-model analyses were performed to determine age-related differences in social and role functioning. We limited our analyses to functioning before psychosis conversion; thus, data of CHR-C participants gathered after psychosis onset were excluded. In controls, social and role functioning improved over time. From at least age 12, functioning in CHR was poorer than in controls, and this lag persisted over time. Between ages 15 and 18, social functioning in CHR-C stagnated and diverged from that of CHR-NC, who continued to improve (p = .001). Subsequently, CHR-C lagged behind in improvement between ages 21 and 23, further distinguishing them from CHR-NC (p < .001). A similar period of stagnation was apparent for role functioning, but to a lesser extent (p = .007). The results remained consistent when we accounted for the time to conversion. Our findings suggest that CHR-C start lagging behind CHR-NC in social and role functioning in adolescence, followed by a period of further stagnation in adulthood.

Antimicrobial usage in food animals increases the prevalence of antimicrobial drug resistance among their enteric bacteria. It has been suggested that this resistance can in turn be transferred to people working with such animals, e.g. abattoir workers. Antimicrobial drug resistance was investigated for Escherichia coli from broilers raised on feed supplemented with antimicrobials, and the people who carry out evisceration, washing and packing of intestines in a high-throughput poultry abattoir in Gauteng, South Africa. Broiler carcasses were sampled from 6 farms, on each of which broilers are produced in a separate 'grow-out cycle'. Per farm, 100 caeca were randomly collected 5 minutes after slaughter and the contents of each were selectively cultured for E. coli. The minimum inhibitory concentration (MIC) of each isolate was determined for the following antimicrobials : doxycycline, trimethoprim, sulphamethoxazole, ampicillin, enrofloxacin, fosfomycin, ceftriaxone and nalidixic acid. The same was determined for the faeces of 29 abattoir workers and 28 persons used as controls. The majority of isolates from broilers were resistant, especially to antimicrobials that were used on the farms in the study. Overall median MICs and the number of resistant isolates from abattoir workers (packers plus eviscerators) tended to be higher than for the control group. However, no statistically significant differences were observed when the median MICs of antimicrobials used regularly in poultry and percentage resistance were compared, nor could an association between resistance among the enteric E. coli from packers and those from broilers be demonstrated.

Abstract.The relationship between Hashimoto’s thyroiditis and vitamin D has been demonstrated in several studies. The aim of the present study was to evaluate vitamin D concentrations in patients with Hashimoto’s thyroiditis, the effect of vitamin D therapy on the course of disease, and to determine changes in thyroid autoantibody status and cardiovascular risk after vitamin D therapy. We included 75 patients with Hashimoto’s thyroiditis and 43 healthy individuals. Vitamin D deficiency is defined as a 25-hydroxy vitamin D (25(OH)D3) concentration less than 20ng/mL. Vitamin D deficient patients were given 50.000 units of 25(OH)D3 weekly for eight weeks in accordance with the Endocrine Society guidelines. All evaluations were repeated after 2 months of treatment. Patients with Hashimoto’s thyroiditis had significantly lower vitamin D concentrations compared with the controls (9.37±0.69 ng/mL vs 11.95±1.01 ng/mL, p < 0.05, respectively). Thyroid autoantibodies were significantly decreased by vitamin D replacement treatment in patients with euthyroid Hashimoto’s thyroiditis. Also, HDL cholesterol concentrations improved in the euthyroid Hashimoto group after treatment. The mean free thyroxine (fT4) concentrations were 0.89±0.02 ng/dL in patients with Hashimoto’s thyroiditis and 1.07±0.03 ng/dL in the healthy control group (p < 0.001). The mean thyroid volumes were 7.71±0.44 mL in patients with Hashimoto’s thyroiditis and 5.46±0.63 mL in the healthy control group (p < 0.01). Vitamin D deficiency is frequent in Hashimoto’s thyroiditis and treatment of patients with this condition with Vitamin D may slow down the course of development of hypothyroidism and also decrease cardiovascular risks in these patients. Vitamin D measurement and replacement may be critical in these patients.

SummaryA dimorphism in the 3’-untranslated region of the prothrombin gene (G to A transition at position 20210) has recently been reported to be associated with increases in plasma prothrombin levels and in the risk of venous thrombosis (1). We have examined the prothrombin dimorphism among 99 unselected outpatients with phlebography verified deep venous thrombosis, and in 282 healthy controls. The prevalence of the 20210 A allele was 7.1% (7/99) in the patient group, and 1.8% (5/282) in the healthy control group (p = 0.0095). The relative risk of venous thrombosis was calculated to be 4.2 (95% Cl, 1.3 to 13.6), and was still significant when adjustment was made for age, sex and the factor V:R506Q mutation causing APC resistance [odds ratio 3.8 (95% Cl, 1.1 13.2)]. As previously reported, 28% of the patients were carriers of the factor V:R506Q mutation. Thus, 34% (one patient carried both traits) of unselected patients with deep venous thrombosis were carriers of an inherited prothrombotic disorder. To sum up, our results confirm the 20210 A allele of the prothrombin gene to be an important risk factor for venous thrombosis.

The article presents the comparative analysis of the state of the cervix in women with endometrial polyps and micropolyps. Patients and methods. The study involved 130 patients aged 18-35 years: 70 patients with endometrial polyps (group I), 30 patients with micropolyps (group II) and 30 patients of the control group (group III). Results. According to the anamnesis of women in the I group were significantly more frequent diseases of the cervix, which corrected physical surgery methods, in particular cryodestruction. In group II, the representatives of these indicators were similar to healthy. Normal colposcopic picture met significantly less frequently in patients and I, and II group. The differences in the incidence of HPV high oncogenic risk in all groups were not statistically significant. Conclusion. Destructive methods used in the detection of any changes in the cervix are often overly aggressive, form scars and contributing to inflamaciones process. In the chain of events leading to the formation of PE, cervical pathology and its correction can take the basic place. Key words: endometrial polyp, micropolyps, chronic endometritis, uterine cervix, colposcopy.

The objective: the study of immunomodulatory effects of a probiotic, which contains lyophilized Lactobacillus (Lactobacillus rhamnosus) – 13 mg (2,0ґ109 CFU) and lyophilized bifidobacteria (Bifidobacterium lactis) – 4 mg (2,0ґ109 CFU) the level of serum immunoglobulin IgA as a marker of local immunity in the plasma of women of reproductive age with the violation of the biocenosis of the vagina. Patients and methods. The study involved 86 patients of reproductive age with the violation of the vaginal biocenosis, which were divided into two groups according to received treatment. A survey was conducted for all patients in both groups: determine the level of serum IgA, measuring pH of vaginal environment and the quantification of lactobacilli and pathogenic flora with the help of test-system «Florotsenoz» before treatment and in 6 weeks after treatment. The state of vaginal microbiocenosis in both groups before treatment was homogeneous. Patients in both groups as therapy at the first stage of treatment received, if necessary antimicrobial therapy depending on the selected flora. In the second stage (restoration of microflora) patient of the main group received systemic probiotic combined with a complex prebiotic local action, patients in the control group, the probiotic localy in the form of the vaginal candles or tablets. Results. The research stated the increasing level of serum IgA in blood plasma of patients of the main group compared to control group at 20%, normalizing the pH of the vaginal environment in the main group in 94% of cases, which indicates an increase of immunity in mucosal. Conclusion. The inclusion of the systemic probiotic in the scheme of treatment of disorders of biocenosis of the vagina system enhances the increasing of immunity of the mucous membranes, and the vaginal tablets prebiotic of local action restores the own normal microflora of the vagina. Key words: serum immunoglobulin A, local immunity, vaginal dysbiosis, probiotics, prebiotics, vaginal microbiocenosis, the pH of the vaginal environment.
