Objective
To determine hepatitis C virus (HCV) genotypes and explore the associated risk factors in chronic HCV patients.Methods
A total of 116 patients with chronic hepatitis C were subjected to polymerase chain reaction (PCR) based detection out of which 112 chronic HCV patients [53 male (47.32%), 59 female (52.68%); mean age (43.76±16.40) years; mean BMI (23.8±3.9) kg] were enrolled in this study. The frequency of 6 HCV genotypes and associated risk factors were evaluated from five districts of North West Frontier Province (NWFP).Results
Genotype 3 was the most prevalent in 73 samples (65.17%) followed by genotype 1 in 24 (21.42%) and genotype 2 in 13 (11.60%) samples. Genotype 3 had significantly high prevalence (P=0.000 2). The results showed that 48 (42.85%) samples were infected with HCV 3a; 25 (22.32%) with 3b; 14 (12.50%) with 1a; 10 (8.92%) with 1b; 11 (9.82%) with 2a; 2 (1.78%) with 2b; and 2 were untypable. The distribution of HCV genotypes in Mardan, Charsadda, Peshawar, Sawabi and Nowshehra districts was different. Use of unsterile equipment for medication, barbers and previous history of hospitalization were the main risk factors for HCV transmission.Conclusions
Genotype 3a and 3b, 1a, 1b and 2a are the common genotypes in NWFP. Genotype 4, 5, and 6 can not be found in a single sample. The level of awareness about various modes of transmission of HCV among the population is found to be very low. 相似文献62.

Disruption of the early stages of information processing in limbic brain circuits may underlie symptoms of severe neuropsychiatric disorders. Prepulse inhibition of acoustic startle (PPI) is diminished in many of these disorders and may reflect the disruption of this CNS function. PPI is associated with brain activity in many of the same regions in humans as it is in laboratory animals, suggesting that neuroimaging studies in humans may help localize deficits that can then be elucidated in animal models. In this article, we employed a rapid presentation event-related design during continuous EPI BOLD scanning to examine hemodynamic response functions (HRFs) associated with PPI. Fourteen healthy participants listened to 100 pulse alone and 100 prepulse combined with pulse (prepulse-pulse) trials. PPI is the normalized difference in the startle response to the two trial types. Following the prepulse-pulse trials, the amplitudes of the HRFs in auditory cortices and in the anterior insula were increased, while in the cerebellum, thalamus and anterior cingulate, they were decreased, relative to the pulse alone trials. In addition, the timing of the prepulse-pulse responses was delayed in the auditory cortices, anterior insula and cerebellum. Finally, PPI measured outside the scanner was predicted by the difference in BOLD responses between trial types in the anterior insula and in the cerebellum. The results suggest that prepulse inhibition, and by extension early stages of information processing, modulate both the amplitude as well as timing of neural activity. 相似文献

Mouse mammary tumor virus (MMTV) is a well-known cause of mammary tumors in mice transmitted as endogenous proviruses or exogenously as infectious virions. The hypothesis that a retrovirus homologous to MMTV is involved in human breast cancers has resulted in renewed interest in the etiology of human breast cancer. Therefore, the detection of MMTV-like exogenous sequences in 30–40 % of invasive breast cancer has increased attention towards this hypothesis. To detect the prevalence of MMTV in Pakistani population, 666-bp-long MMTV envelop and 630-bp LTR sequences were amplified from breast cancer patient samples (tissue biopsies and peripheral blood) using mouse with mammary tumor as control. MMTV-like virus env and LTR DNA sequences were detected in 20 and 26 % of breast tumor samples, respectively, from the total of 80 breast cancer patients’ blood and tissue samples. No significant association was observed between age, grade of disease, and lymph node involvement with the prevalence of MMTV-like sequences. Our data add to the growing number of studies implicating MMTV-like virus in human breast cancer, but still clear causal association of MMTV to breast cancer remains to be reputable. 相似文献

The Lifestyle Management Programme (LMP) is an exercise and weight management programme with physiotherapy support for people with hip or knee osteoarthritis (OA) and a body mass index (BMI) over 35. This qualitative study explored views and experiences of the LMP among patients and professionals, and offers insight for future programmes. Five referring clinicians and six delivering professionals participated in focus groups. Three referring GPs and nine patients who attended the LMP took part in semi‐structured interviews. Topics included: referral, reasons for taking up and continuing the programme or not, and experiences and outcomes. Framework method was used to analyse the qualitative data. Overall, patients and professionals valued the multidisciplinary nature of the LMP. However, professionals explained feeling guilty about delaying patients on the orthopaedic waiting list and believed that the programme should be redirected to those with less severe OA and a lower BMI. Referring clinicians differed in their interpretation of the referral criteria and expressed varying levels of autonomy when making referrals. Patients referred after a consultation with their general practitioner appeared to be more satisfied with the referral process. Patients were also encouraged by the opportunity to improve health, their likelihood of surgery and social benefits. However, patients were discouraged by inconvenience, cost, lack of readiness to change and embarrassment. In conclusion, shared decision‐making about lifestyle management without delaying orthopaedic opinion is preferable, and more psychological support may increase participation. Importantly, the programme may be better focused on rehabilitation for patients with a lower BMI and less severe symptoms. 相似文献

ABSTRACTSexual minority women (SMW) face both increased risk for unintended pregnancy and barriers to achieving wanted pregnancy, but little research investigates SMW’s pregnancy desires. To fill this gap, we conducted five focus groups and 11 in-depth interviews with 20-30-year-old SMW in three US cities. Findings highlight that the heteronormative pregnancy planning paradigm lacks salience for SMW. While some SMW clearly wish to avoid pregnancy, many others are unsure, and factors influencing this uncertainty include relationship context, anticipating logistical barriers, and discord between queer identity and pregnancy. 相似文献

Background
We hypothesized that changes in International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) prognostic category at start of second-line therapy (2L) for metastatic renal cell carcinoma (mRCC) might predict response.Objective
To assess outcomes of 2L according to type of therapy and change in IMDC prognostic category.Design, setting, and participants
We performed a retrospective review of the IMDC database for mRCC patients who received first-line (1L) VEGF inhibitors (VEGFi) and then 2L with VEGFi or mTOR inhibitors (mTORi). IMDC prognostic categories were defined before each line of therapy (favorable, F; intermediate, I; poor, P). Data were analyzed for 1516 patients, of whom 89% had clear cell histology.Intervention
All included patients received targeted therapy for mRCC.Outcome measurements and statistical analysis
Overall survival (OS), time to treatment failure, and response to 2L were analyzed using Cox or logistic regression.Results and limitations
At start of 2L, 60% of patients remained in the same prognostic category; 9.0% improved (3% I → F; 6% P → I); 31% deteriorated (15% F → I or P; 16% I → P). Patients with the same or better IMDC prognostic category had a longer time to treatment failure if they remained on VEGFi compared to those who switched to mTORi (adjusted hazard ratio [AHR] ranging from 0.33 to 0.78, adjusted p < 0.05). Patients who deteriorated from F to I appeared more likely to benefit from switching to mTORi (median OS 16.5 mo, 95% confidence interval [CI] 12.0–19.0 for VEGFi; 20.2 mo, 95% CI 14.3–26.1 for mTORi; AHR 1.53, 95% CI 1.04–2.24; adjusted p = 0.03).Conclusions
Changes in IMDC prognostic category predict the subsequent clinical course for patients with mRCC and provide a rational basis for selection of subsequent therapy.Patient summary
The pattern of treatment failure might help to predict what the next treatment should be for patients with metastatic renal cell carcinoma. 相似文献69.

Background While there is considerable variability with respect to attendance at the postpartum visit, not much is known about women’s preferences with respect to postpartum care. Likewise, there is also limited information on providers’ practices regarding the postpartum visit and care including the delivery of contraception. To understand and address deficits in the delivery and utilization of postpartum care, we examined the perceptions of low-income postpartum women with respect to barriers to and preferences for the timing and location of the postpartum visit and receipt of contraception. We also examined providers’ current prenatal and postnatal care practices for promoting the use of postpartum care and their attitudes toward alternative approaches for delivering contraceptive services in the postpartum period. Methods Qualitative face-to-face interviews were completed with 20 postpartum women and in-depth qualitative phone interviews were completed with 12 health care providers who had regular contact with postpartum women. Interviews were coded using Atlas.ti software and themes were identified. Results Women believed that receiving care during the postpartum period was an important resource for monitoring physical and mental health and also strongly supported the provision of contraception earlier than the 6-week postpartum visit. Providers reported barriers to women’s use of postpartum care on the patient, provider, and system levels. However, providers were receptive to exploring new clinical practices that may widen the reach of postpartum care and increase access to postpartum contraception. Conclusion Approaches that increase the flexibility and convenience of postpartum care and the delivery of postpartum contraception may increase the likelihood that women will take advantage of essential postpartum services. 相似文献
