Sixty-three patients with Salmonella typhi infections were randomly assigned to receive either ceftriaxone iv in single daily doses of 75 mg/kg for children and 3-4 g for adults for seven days or to receive 60 mg of chloramphenicol/kg a day orally or iv in four divided doses until defervescence and then 40 mg/kg a day to complete 14 d. In the ceftriaxone group, one death occurred, and two of seven patients still febrile 11 d after starting treatment were given chloramphenicol. In the chloramphenicol group, one death and one gastrointestinal perforation occurred. The probability of remaining febrile was similar for both groups during the first seven days but was significantly greater for patients receiving ceftriaxone during the 14-d period. Patients in the chloramphenicol group were more likely to be bacteremic on day 3. These results suggest that a seven-day course of once-daily ceftriaxone shows promise as an alternative to 14 d of chloramphenicol for treating typhoid fever. 相似文献
Domestic violence (DV) by husbands or in-laws is a recognized problem in many countries and is associated with a wide range of adverse mental health outcomes. However, detailed knowledge on the relationship between DV experience and postpartum depression (PPD) is essential to design appropriate interventions. Therefore, this study assesses the relationship between maternal experience of DV perpetrated by husbands or in-laws and PPD in Bangladesh.
Methods
A cross-sectional survey was conducted from October to December 2019 among 497 mothers within the first 6 months postpartum who attended a health center in Rajshahi City Corporation, Bangladesh. Multivariable logistic regressions were performed to identify the associations after controlling for potential confounders.
Results
The prevalence of PPD in this sample was 34% within the first 6 months after birth; 58.6% of mothers reported having experienced any form of DV in their lifetime. Maternal experience of any form of DV (Adjusted Odds Ratio [AOR] = 1.87; 95% confidence interval [CI] = 1.19–2.93) was associated with PPD, as were experiences of any physical DV (AOR = 2.25; 95% CI = 1.40–3.59), emotional DV (AOR = 2.07; 95% CI = 1.34–3.19), and controlling behavior (AOR = 1.69; 95% CI = 1.08–2.66). Additionally, the likelihood of PPD significantly increased among women who experienced more forms of DV.
Conclusion
DV perpetrated by husband and/or in-laws is highly prevalent and significantly associated with PPD in Bangladesh. Strategies in developing interventions for improving maternal mental health should consider DV perpetrated by either husband or in-laws.
Multicentric reticulohistiocytosis (MRH) is a rare systemic inflammatory granulomatous disease that primarily manifests clinically with severe erosive arthritis and widespread papulonodular skin lesions but can involve multiple other organ systems. Despite the fact that this condition can become aggressive, debilitating as well as deforming with significant detrimental consequences, the etiology of this disease remains poorly understood. Moreover, the fact that MRH is such an uncommon disease has created an obstacle in the path of adequate clinical trials that are needed for better understanding of this phenomenon and for the development of treatment options for this patient population. In this review, we will attempt to discuss the epidemiology, pathophysiology, clinical features, associated conditions, differential diagnoses, diagnostic workup, and available treatments of MRH with the hope of creating a better understanding of this very challenging yet elusive disease process. 相似文献
Light scattering has been used for label-free cell detection. The angular light scattering patterns from the cells are unique to them based on the cell size, nucleus size, number of mitochondria, and cell surface roughness. The patterns collected from the cells can then be classified based on different image characteristics. We have also developed a machine learning (ML) method to classify these cell light scattering patterns. As a case study we have used this light scattering technique integrated with the machine learning to analyze staurosporine-treated SH-SY5Y neuroblastoma cells and compare them to non-treated control cells. Experimental results show that the ML technique can provide a classification accuracy (treated versus non-treated) of over 90%. The predicted percentage of the treated cells in a mixed solution is within 5% of the reference (ground-truth) value and the technique has the potential to be a viable method for real-time detection and diagnosis. 相似文献
Diosmin, a naturally occurring flavonoid commonly present in citrus fruit, is known to exhibit anti‐inflammatory, antimutagenic, antioxidant, and free radical scavenging as well as blood lipid lowering activities among others. Diosmin has also been used for the treatment of various diseases including diabetes mellitus and Alzheimer's disease. Our study explores the role of Diosmin in pulmonary toxicity (lung injury) induced by environmental contaminant benzo(a)pyrene [B(a)P]. Swiss Albino Mice (SAM) were administered with either Diosmin 100 or 200 mg/kg body weight daily for 14 days and then challenged with a single dose of B(a)P. On the 15th day, animals were sacrificed; lung tissues and blood were collected for molecular analysis. B(a)P administration in mice induced the thickening of lung epithelium, damaged alveolar architecture, and promoted inflammatory cell infiltration in the lung tissues. Also, B[a]P significantly increased the expression of NF‐kB, COX‐2, IL‐6, Bax, cleaved caspase 3, and cleaved PARP proteins and decreased antioxidant enzyme levels. Diosmin‐100 and Diosmin‐200 significantly attenuated the damage to lung epithelium, alveolar architecture, and reduced inflammatory cell infiltration in the lung tissues of mice. Diosmin significantly (P < .05) attenuated the levels of oxidative stress markers: lactate dehydrogenase and xanthine oxidase. A decrease in expression of NF‐kB, COX‐2, IL‐6, Bax, cleaved caspase 3, and cleaved PARP proteins in mice was challenged with B[a]P. Diosmin thus could be a promising therapeutic adjuvant against B[a]P‐induced oxidative stress and lung damage. 相似文献
Iliac crest trephine biopsy specimens from 16 patients treated with recombinant alpha 2-interferon (alpha-IFN) for hairy cell leukemia (HCL) were examined for reticulin and collagen content. These data were compared with the hairy cell index (HCl), the proportion of hairy cells to the overall cellularity of the bone marrow. Specimens were studied immediately before alpha-IFN therapy, at 6-month intervals during, and in six patients 6 months after cessation of therapy. All patients presented with increased bone marrow fibrosis ranging from focally increased reticulin to a diffuse increase in both reticulin and collagen content. This fibrosis was observed to decrease during alpha- IFN therapy inasmuch as the hairy cell population was diminished in the bone marrow in 13 patients. Regression analysis of HCl v bone marrow fibrosis showed a positive correlation (r = .73, P less than .02). Six patients demonstrated a reduction in bone marrow reticulin and collagen to normal levels during alpha-IFN therapy. Two of six patients demonstrated increased bone marrow fibrosis and HCl 6 months after cessation of alpha-IFN therapy. Three of 16 patients exhibited no decrease in bone marrow reticulin content during therapy despite a decreased bone marrow hairy cell population. 相似文献
