The correlation between Toxoplasma gondii infection and prenatal depression in pregnant women.

Previous studies have demonstrated that latent toxoplasmosis is associated with neuropsychiatric disorders. We evaluated the correlation between Toxoplasma gondii infection and prenatal depression. In this case-control study, we enrolled 116 depressed pregnant women and 244 healthy controls. The Edinburgh Postpartum Depression Scale (EPDS) was used to evaluate the depression symptom severity in study participants. All participants were screened for the anti-Toxoplasma IgG by enzyme-linked immunosorbent assay. Seroprevalence of T. gondii did not significantly differ between the depressed pregnant women and healthy controls (OR = 1.4; 95 % CI = 0.9-2.19; P = 0.142). T. gondii IgG titer was significantly higher in depressed women (18.6 ± 10.9 IUs) than those in the control group (13.6 ± 8.1 IUs) (z = -5.36, P < 0.001). The T. gondii-positive depressed women showed a positive correlation of T. gondii IgG titer with the EPDS scores (r = 0.52; P < 0.01). The mean EPDS score was also significantly higher in the T. gondii-positive depressed women (20.7 ± 2.7) compared with the controls (18.36 ± 2.7) (P < 0.001). The results obtained from the current study revealed that T. gondii infection might affect susceptibility to depression and severity of depressive symptoms in pregnant women, particularly in those patients who have high antibody titers. Further study is required to fully elucidate the characteristics and mechanisms of this association.

Informational needs of patients with metastatic breast cancer: what questions do they ask, and are physicians answering them?

In the setting of breast oncology consultations, we sought to understand communication patterns between patients with advanced breast cancer and their oncologists during visits with Decision Support Services. This is a descriptive study analyzing themes and their frequencies of premeditated question lists of patients with metastatic breast cancer. We identified topics physicians most commonly discussed among themes previously found, documenting questions patients with metastatic breast cancer prepare for physician consultations and oncologists' response. Inclusion criteria were as follows: diagnosis of metastatic breast cancer, completion of a question list before meeting with an oncologist, and receipt of a summary of the consultation. We identified 59 women with metastatic breast cancer who received both documents. We reviewed the question lists and consultation summaries of these patients. Of the 59 patients whose documents we reviewed, patients most often asked about prognosis (38), symptom management (31), clinical trials (43), and quality of life (38). Physicians answered questions about prognosis infrequently (37% of the time); other questions that were answered more than commonly are the following: symptom management (81%), clinical trials (79%), and quality of life (66%). Breast cancer patients have many questions regarding their disease, its treatment, and symptoms, which were facilitated in this setting by Decision Support Services. Question lists may be insufficient to bridge the divide between physicians and patient information needs in the setting of metastatic breast cancer, particularly regarding prognosis. Patients may need additional assistance defining question lists, and physicians may benefit from training in communication, particularly regarding discussions of prognosis and end of life.

Global prevalence of latent toxoplasmosis in pregnant women: a systematic review and meta-analysis.

BACKGROUND: Toxoplasma gondii infection, if acquired as an acute infection during pregnancy, can have substantial adverse effects on mothers, fetuses and newborns. Latent toxoplasmosis also causes a variety of pathologies and has been linked to adverse effects on pregnancy. OBJECTIVE: Here, we present results of a comprehensive systematic review and meta-analysis of the global prevalence of latent toxoplasmosis in pregnant women. DATA SOURCE: We searched PubMed, EMBASE, Web of Science, SciELO and Scopus databases for relevant studies that were published between 1 January 1988 and 20 July 2019. STUDY ELIGIBILITY CRITERIA: All population-based, cross-sectional and longitudinal studies reporting the prevalence of latent toxoplasmosis in healthy pregnant women were considered for inclusion. PARTICIPANTS: Pregnant women who were tested for prevalence of latent toxoplasmosis. INTERVENTIONS: There were no interventions. METHOD: We used a random effects model to calculate pooled prevalence estimates with 95% confidence intervals (CIs). We grouped prevalence data according to the geographic regions defined by the World Health Organization (WHO). Multiple subgroup and meta-regression analyses were performed. RESULTS: In total, 311 studies with 320 relevant data sets representing 1 148 677 pregnant women from 91 countries were eligible for inclusion in the meta-analysis. The global prevalence of latent toxoplasmosis in pregnant women was estimated at 33.8% (95% CI, 31.8-35.9%; 345 870/1 148 677). South America had the highest pooled prevalence (56.2%; 50.5-62.8%) of latent toxoplasmosis in pregnant women, whereas the Western Pacific region had the lowest prevalence (11.8%; 8.1-16.0%). A significantly higher prevalence of latent toxoplasmosis was associated with countries with low income and low human development indices (p < 0.001). CONCLUSION: Our results indicate a high level of latent toxoplasmosis in pregnant women, especially in some low- and middle-income countries of Africa and South America, although the local prevalence varied markedly. These results suggest a need for improved prevention and control efforts to reduce the health risks to women and newborns.

Effects of combined AT1 receptor antagonist/NEP inhibitor on vascular remodeling and cardiac fibrosis in SHRSP.

BACKGROUND: The association of an angiotensin-converting enzyme inhibitor (ACEI) with a neutral endopeptidase inhibitor (NEPI) has potent blood pressure (BP) lowering action, but is associated with side-effects. We evaluated the effects of combining an angiotensin II type 1 (AT1) receptor blocker (ARB, valsartan) and a NEPI (CGS 25354) in comparison with a dual ACEI/NEPI (CGS 30440) in stroke-prone spontaneously hypertensive rats (SHRSP). METHODS AND RESULTS: Ten-week-old SHRSP were treated with valsartan (10 mg/kg per day), valsartan + CGS 25354 (100 mg/kg per day), CGS 25354, CGS 30440 (10 mg/kg per day) or hydralazine (25 mg/kg per day) for 10 weeks. Mesenteric resistance arteries were studied on a pressurized myograph, whereas cardiac effects were assessed by histology and immunohistochemistry. BP of SHRSP was lowered by combined valsartan/NEPI and ACEI/NEPI slightly more than valsartan, whereas NEPI was ineffective. Valsartan, valsartan/NEPI and ACEI/NEPI normalized resistance artery relaxation responses to acetylcholine, and significantly decreased media/lumen ratio and collagen deposition. All treatments decreased vascular NAD(P)H oxidase-mediated superoxide production. Valsartan/NEPI and ACEI/NEPI decreased media/lumen ratio of intramyocardial coronary arteries, while valsartan alone had no effect. Valsartan/NEPI and ACEI/NEPI increased vascular matrix metalloproteinase-2 activity, and decreased tissue inhibitors of metalloproteinase-2 activity and macrophage infiltration. CONCLUSION: Combined valsartan/NEPI was almost as effective as a dual ACEI/NEPI in lowering BP and improving vascular remodeling in SHRSP. These findings suggest the potential therapeutic value of combining ARB and NEPI in the treatment of hypertension.

An assessment of the relative impact of hidradenitis suppurativa, psoriasis, and obesity on quality of life.

BACKGROUND: Hidradenitis suppurativa (HS) and psoriasis are inflammatory skin diseases associated with obesity. Each disease is likely to impact the quality of life of patients, but the relative impact of each disease is unknown. OBJECTIVES: This study aimed to determine whether skin disease or obesity is more distressing to obese patients who have either psoriasis or HS. METHODS: A cohort of obese patients with psoriasis and HS was surveyed using a time-trade-off utility. T-tests and regression analysis were used to compare differences in impact on quality of life between skin disease and obesity for patients with HS and psoriasis. Further analyses were adjusted for degree of obesity and severity of disease. RESULTS: A total of 79 subjects completed the survey. Obese patients with HS were heavier than patients with psoriasis (mean body mass index 38.1 kg/m2 vs. 34.9 kg/m2). Obese patients with either HS or psoriasis were both willing to trade a significantly higher proportion of their life to live without skin disease than to live at a normal weight (p = .01). This effect persisted after controlling for disease severity and weight. Patients with HS were willing to trade significantly more years of life to live at a normal weight than obese patients with psoriasis (14 vs. 7; p < .04). LIMITATIONS: This was a small study conducted at an academic institution. CONCLUSION: In this study population, obesity was more severe in patients with HS than in those with psoriasis. Even after controlling for relative severity, HS was more problematic for subjects in this study than weight when these conditions existed concomitantly.

Potential contribution of the forestry sector in Bangladesh to carbon sequestration.

The Kyoto Protocol provides for the involvement of developing countries in an atmospheric greenhouse gas reduction regime under its Clean Development Mechanism (CDM). Carbon credits are gained from reforestation and afforestation activities in developing countries. Bangladesh, a densely populated tropical country in South Asia, has a huge degraded forestland which can be reforested by CDM projects. To realize the potential of the forestry sector in developing countries for full-scale emission mitigation, the carbon sequestration potential of different species in different types of plantations should be integrated with the carbon trading system under the CDM of the Kyoto Protocol. This paper discusses the prospects and problems of carbon trading in Bangladesh, in relation to the CDM, in the context of global warming and the potential associated consequences. The paper analyzes the effects of reforestation projects on carbon sequestration in Bangladesh, in general, and in the hilly Chittagong region, in particular, and concludes by demonstrating the carbon trading opportunities. Results showed that tree tissue in the forests of Bangladesh stored 92tons of carbon per hectare (tC/ha), on average. The results also revealed a gross stock of 190tC/ha in the plantations of 13 tree species, ranging in age from 6 to 23 years. The paper confirms the huge atmospheric CO(2) offset by the forests if the degraded forestlands are reforested by CDM projects, indicating the potential of Bangladesh to participate in carbon trading for both its economic and environmental benefit. Within the forestry sector itself, some constraints are identified; nevertheless, the results of the study can expedite policy decisions regarding Bangladesh's participation in carbon trading through the CDM.

Ifosfamide encephalopathy.

We describe a case of reversible encephalopathy caused by the recently released anticancer drug Ifosfamide. The clinical course, role of EEG in monitoring and predicting encephalopathy, and putative mechanism of neurotoxicity is discussed. Short infusion times and/or prior CNS disease may increase the risk of encephalopathy.
