Background
Young patients with breast cancer treated with chemotherapy can experience ovarian failure, which can lead to chemotherapy-induced menopause (CIM) impacting the quality of life (QoL). A prospective study was set out to evaluate the impact of CIM on QoL in women of childbearing age with non-metastatic breast cancer, and this article reports results of the interim analysis conducted to evaluate feasibility and to see preliminary results.Patients and Methods
A total of 58 women (age, 18-46 years) with newly diagnosed breast cancer and treated with chemotherapy were eligible. QoL was assessed by self-administered questionnaires (Quality of Life Questionnaire-Core 30 [QLQ-C30], Quality of Life Questionnaire-Breast 23 [QLQ-BR23], and Kupperman index) and hormonal variations (anti-Müllerian hormone [AMH], follicle-stimulating hormone, and estradiol) were explored. We compared patients with ≥ 12 months amenorrhea (CIM) (n = 41) to patients with < 12 months of amenorrhea (non-CIM) (n = 17).Results
A good inclusion rate (approximately 4/month) and sufficient data enabled us to perform this analysis. QLQ-C30 failed to show any difference between CIM and non-CIM patients (P = .5). In contrast, at 6 months post-chemotherapy, CIM patients tended to have lower QoL as shown by QLQ-BR23 (P = .16) and more severe climacteric symptoms (P = .01). Regarding hormonal variations, AMH pre-treatment level was higher in non-CIM patients (P = .0032). We also noted that CIM patients were older (P = .00013), had shorter menstruation cycle (P = .082), and experienced faster amenorrhea (P = .088).Conclusions
The study is technically feasible, and our preliminary results underline that age in association with pre-treatment AMH level could be helpful to predict ovarian function. QLQ-BR23 seemed to be stronger, more precise, and appropriate to evaluate QoL changes in patients with breast cancer than the QLQ-C30. 相似文献82.
There is paucity of data on prevalence of hypertension and its effects on HIV/AIDS progression among patients at Kenyatta National Hospital (KNH), Kenya. This was a cross sectional study conducted between January and May 2015 at the KNH HIV Care Centre. Ethical approval was obtained from institutional ethics review board. HIV positive adult patients were recruited sequentially, and written informed consent obtained from each participant. Systematic sampling was used to select participants who were screened for blood pressure, body mass index (BMI) and lifestyle characteristics. Data on clinical parameters were extracted from patient records. A total of 297 participants (89 males and 208 females) were enrolled in the study. The participants were socially diverse in cultural beliefs, religious practices and lifestyles. Their ages ranged from 30 to 57 years, and the average age of males (M?=?44.56, SD?=?6.05) was higher than females (M?=?42.29, SD?=?6.16), p?.01. The prevalence of hypertension was found to be 23.2%. The relation between CD4 counts and creatinine was statistically significant, p?.01, as was the association between CD4 counts and BMI, p?.01. Hypertension is a highly prevalent co-morbidity in HIV patients. The risk factors include prolonged use of ART as well as increased body mass index. The effects of hypertension on HIV progression include low CD4+ T cell counts which complicate the underlying immunosuppression. 相似文献

BACKGROUNDThymic epithelial carcinomas are rare and have a poor prognosis. Treatment of thymic epithelial carcinoma is multimodal and includes surgery, post-operative radiation therapy, adjuvant and neoadjuvant chemotherapy, or exclusive chemotherapy based on disease resectability. However, there is currently no standard treatment regimen for metastatic and recurrent thymic carcinoma. CASE SUMMARYA 45-year-old Caucasian male, with no past medical history, presented with hepatalgia and a cervical mass. A computed tomography (CT) scan showed multiple suspect lesions in the lungs, liver, and anterior mediastinum associated with mediastinal and cervical adenopathy. CT-guided percutaneous biopsies of the liver lesions and anterior mediastinal mass were performed, confirming the histopathology of thymic epithelial carcinoma. Management consisted of several chemotherapy regimens and radiation therapy, administered between April 2016 and December 2018. The patient achieved complete metabolic response. Fluorodeoxyglucose positron emission tomography/CT performed in June 2019 showed disease relapse, with reappearance of a large hypermetabolic hepatic mass and involvement of mediastinal and axillary lymph nodes. Intravenous pembrolizumab (200 mg, every 3 wk) was administered after two prior systemic therapies. The patient’s response to treatment was last documented on March 5, 2020.CONCLUSIONPembrolizumab was successful in treatment of a patient with programmed death-ligand 1-negative metastatic thymic carcinoma, pretreated with chemotherapy. 相似文献

Microscopic diagnosis of malaria is a well-established and inexpensive technique that has the potential to provide accurate diagnosis of malaria infection. However, it requires both training and experience. Although it is considered the gold standard in research settings, the sensitivity and specificity of routine microscopy for clinical care in the primary care setting has been reported to be unacceptably low. We established a monthly external quality assurance program to monitor the performance of clinical microscopy in 17 rural health centers in western Kenya. The average sensitivity over the 12-month period was 96% and the average specificity was 88%. We identified specific contextual factors that contributed to inadequate performance. Maintaining high-quality malaria diagnosis in high-volume, resource-constrained health facilities is possible. 相似文献

BACKGROUND & AIMS: Adefovir dipivoxil effectively inhibits both hepatitis B virus (HBV) replication and disease activity in patients with chronic hepatitis B. Resistance to treatment was not observed in 2 recent large placebo-controlled 48-week studies with this drug. The aim of this study was to characterize adefovir resistance in a patient who developed clinical and virologic evidence of breakthrough during a 96-week course of treatment. METHODS: HBV DNA was PCR amplified and sequenced. Phenotypic studies used patient-derived HBV as well as specific mutations created by site-directed mutagenesis of a HBV/baculovirus recombinant. RESULTS: Following the commencement of treatment with adefovir dipivoxil, the patient initially responded with a 2.4 log(10) decrease in serum HBV DNA and normalization of alanine aminotransaminase levels by week 16. During the second year of treatment, however, serum HBV DNA rose progressively, eventually returning to near-pretreatment levels. This increase in viral replication was associated with a marked increase in alanine aminotransferase and mild changes in bilirubin, albumin, and prothrombin time. Comparison of pretreatment and posttreatment HBV DNA by polymerase chain reaction sequencing identified a novel asparagine to threonine mutation at residue rt236 in domain D of the HBV polymerase. In vitro testing of a laboratory strain encoding the rtN236T mutation and testing of patient-derived virus confirmed that the rtN236T substitution caused a marked reduction in susceptibility to adefovir. CONCLUSIONS: The development of this novel mutation in the HBV polymerase confers resistance to adefovir dipivoxil. The patient responded to subsequent lamivudine therapy, achieving normalization of alanine aminotransferase and a significant decrease in serum HBV DNA. 相似文献

Nurse retention is widely acknowledged as a crucial international workforce issue, yet the concept remains ambiguous. This study focuses on a concept analysis in an effort to clarify the attributes of nurse retention, including its antecedents and consequences. The Walker and Avant approach was applied to analyze the concept of nurse retention. Four key attributes of nurse retention were identified in the analysis, specifically motivation, intention, and individual decision; strategy and intervention; geographic context; and attachment to work. Antecedents of nurse retention included the healthcare system at the macro level, the health care facility, health personnel, and living conditions. Retention has consequences for individual nurses, the healthcare organization, and the overall health system. Our concept analysis provides clarification to better understand nurse retention along with its implications for the healthcare workforce. The analysis further emphasizes the importance of retention as a comprehensive priority issue for human resources when recruiting and maintaining the nursing workforce internationally. 相似文献
