Measured and estimated glomerular filtration rates in voluntary kidney donors - before and after nephrectomy.
INTRODUCTION :
The assessment of renal functions has always remained a challenge for
nephrologists. The accurate assessment is paramount for several reasons like categorizing
patients into the different groups, comparison of renal function amongst different
populations, determining the therapeutic measures needed at different categories of renal
dysfunction in chronic kidney disease patients and so on. The simple measurement of
plasma creatinine and the estimated glomerular filtration rate (GFR) using the various
equations have been the mainstay of renal function assessment in the bedside. The other
methods of direct measurement are cumbersome to perform on a day-to-day basis and are
quite expensive. This has forced the nephrology community to accept the former
(compromising on the accuracy) to that of the latter methods. Several new methods like
the technetium 99m-labeled diethylene triaminopentaacetic acid (99mTc-DTPA) renal
scintigraphy have been claimed to measure GFR accurately. But these have not been
standardized. Also various biochemical markers like cystatin C (CysC) and beta- 2
microglobulin have been claimed to reflect smaller degrees of renal changes better but
have not come into widespread clinical use. AIM :
To assess the correlation between measured and estimated GFR in voluntary kidney donors, pre and post
nephrectomy and to determine the post-nephrectomy GFR in VKDs.
MATERIALS AND METHODS :
Pre- and post-nephrectomy (after 3 months) GFR measurement was done by 99mTcDTPA scintigraphy and
estimations using creatinine (CG, MDRD formulae) and serum Cystatin C (Grubb’s equation).
DISCUSSION :
Forty-three donors (15 males, mean age of 43.02 ± 12.05 years) were studied. CG estimations used actual
and lean body weight (CGGFRA, CGGFRL). Modification of diet in renal diseases formula used MDRD1
and MDRD2 formulae. The measured values were 92.37 ± 26.79-ml/min/1.73 m2 at baseline and 53.58 ±
17.18-ml/min/1.73 m2 after 3 months. The estimated values at the same time points by CGGFRA,
CGGFRL, MDRD1 and MDRD2 were 78.34 ±16.30, 58.12 ±12.35, 84.61± 15.68, 90.82 ± 19.29
ml/min/1.73 m2 respectively, pre-nephrectomy and 56.78 ± 12.90, 42.42 ± 10.00, 62.07 ± 11.34 61.67 ±
12.33 ml/min/1.73 m2 respectively, post-nephrectomy. As CysC is better predictor of changes in GFR, it
was performed in a subset (n=21). The Pre- and post- nephrectomy CysC GFR using the Grubb’s equation
was 90.48 ± 28.04 and 56.73 ± 15.87- ml/min/1.73 m2. Significant intraclass correlation coefficient was
noted between 99mTCDTPA GFR and CysCGFR (0.83 and 0.67, pre and post), but not with others. CG and
MDRD GFRs had correlation. Post-nephrectomy GFR decline by all methods were significant with
99mTCDTPA GFR (41.99%) recording the maximum decline.
CONCLUSION :
Cystatin C GFR predicts 99mTC-DTPA GFR reasonably well, pre- and post-nephrectomy. Creatinine based
estimated GFRs don’t. However, CG and MDRD have acceptable correlation between them.
The post-nephrectomy decline in the GFR was significant by all methods with the highest decline noted
with 99m TC-DTPA
Examining the Determinants of Sexual Violence Among Young, Married Women in Southern India
The prevalence of sexual violence is increasingly being studied in India. Yet the determinants of sexual violence, irrespective of physical violence, remain largely unexplored. Here the authors identify the determinants of sexual violence, and additionally, explore how the presence of physical violence modifies these determinants. A cross-sectional analysis is conducted using baseline data from a longitudinal study involving young married women attending reproductive health clinics in Southern India. A multivariable logistic regression analysis is conducted to first identify determinants of sexual violence and then repeated after stratifying elements based on presence or absence of physical violence identified from participants’ reports. 36% and 50% of the participants report experiencing sexual and physical violence, respectively. After adjusting for other covariates, women’s partners’ characteristics are found most significantly associated with their odds of experiencing sexual violence. These characteristics include husbands’ primary education, employment as drivers, alcohol consumption, and having multiple sex partners. Women’s contribution to household income also increases their odds of experiencing sexual violence by almost twofold; however, if they are solely responsible for “all” household income, the relationship is found to be protective. Physical violence modifies the determinants of sexual violence, and among women not experiencing physical violence, husbands’ primary education and employment as drivers increase women’s odds of experiencing sexual violence nearly threefold, and women who contribute “all” the household income (n = 62) do not experience sexual violence. These relationships are not significant among women experiencing physical violence. Study findings improve the understanding of the determinants of sexual violence. Future research is needed to examine the risk factors for different types of GBV independently and to tease apart the differences in risk factors depending on women’s experiences. The significance of male partners’ characteristics warrants in-depth research, and in order to promote gender-equitable norms, future interventions need to focus on male behaviors and men’s day-to-day survival challenges, all of which likely influence conflicts in marital relationships
Time trends of cigarette and waterpipe smoking among a cohort of school children in Irbid, Jordan, 2008–11
Background: Coordinated high-impact interventions and community-level changes in smoking behaviour norms effectively reduced prevalence of smoking among youth in many developed countries. Smoking trends among Jordanian adolescents are likely different than their Western counterparts and must be understood in the context of their daily lives to tailor interventions specifically for adolescents in this setting. Methods: Between 2008 and 2011, a school-based longitudinal study was conducted in Irbid, Jordan. All seventh-grade students in 19 randomly selected schools (of 60) were surveyed annually for 4 years. Outcomes of interest were time trends in smoking behaviour, age at initiation and change in frequency of smoking. Results: Among 1781 participants, baseline prevalence of current smoking (cigarettes or waterpipe) for boys was 22.9% and 8.7% for girls. Prevalence of ever-smoking and current any smoking, cigarette smoking, waterpipe smoking and dual cigarette/waterpipe smoking was significantly higher in boys than girls each year (P \u3c 0.001). Smoking prevalence increased every year after year 2 for current smoking (P \u3c 0.05) across all methods (any, cigarette, waterpipe and dual). At all time points for both boys and girls, prevalence of waterpipe smoking was higher than that of cigarette smoking (P \u3c 0.001). Conclusion: This study shows intensive smoking patterns at early ages among Jordanian youth in Irbid, characterized by a predominance of waterpipe smoking and steeper age-related increase in cigarette smoking. It also points to the possibility of waterpipe being the favourite method for introducing youth to tobacco, as well as being a vehicle for tobacco dependence and cigarette smoking
Traditional birth attendants lack basic information on HIV and safe delivery practices in rural Mysore, India
<p>Abstract</p> <p>Background</p> <p>There is little research on HIV awareness and practices of traditional birth attendants (TBA) in India. This study investigated knowledge and attitudes among rural TBA in Karnataka as part of a project examining how traditional birth attendants could be integrated into prevention-of-mother-to-child transmission of HIV (PMTCT) programs in India.</p> <p>Methods</p> <p>A cross-sectional survey was conducted between March 2008 and January 2009 among TBA in 144 villages in Mysore <it>Taluk</it>, Karnataka. Following informed consent, TBA underwent an interviewer-administered questionnaire in the local language of <it>Kannada </it>on practices and knowledge around birthing and HIV/PMTCT.</p> <p>Results</p> <p>Of the 417 TBA surveyed, the median age was 52 years and 96% were Hindus. A majority (324, 77.7%) had no formal schooling, 88 (21.1%) had up to 7 years and 5 (1%) had more than 7 yrs of education. Only 51 of the 417 TBA (12%) reported hearing about HIV/AIDS. Of those who had heard about HIV/AIDS, only 36 (72%) correctly reported that the virus could be spread from mother to child; 37 (74%) identified unprotected sex as a mode of transmission; and 26 (51%) correctly said healthy looking people could spread HIV. Just 22 (44%) knew that infected mothers could lower the risk of transmitting the virus to their infants. An overwhelming majority of TBA (401, 96.2%) did not provide antenatal care to their clients. Over half (254, 61%) said they would refer the woman to a hospital if she bled before delivery, and only 53 (13%) felt referral was necessary if excessive bleeding occurred after birth.</p> <p>Conclusions</p> <p>Traditional birth attendants will continue to play an important role in maternal child health in India for the foreseeable future. This study demonstrates that a majority of TBA lack basic information about HIV/AIDS and safe delivery practices. Given the ongoing shortage of skilled birth attendance in rural areas, more studies are needed to examine whether TBA should be trained and integrated into PMTCT and maternal child health programs in India.</p
A Systematic Review of interventions to Promote Hpv Vaccination Globally
BACKGROUND: Despite the human papillomavirus (HPV) vaccine being a safe, effective cancer prevention method, its uptake is suboptimal in the United States (U.S.). Previous research has found a variety of intervention strategies (environmental and behavioral) to increase its uptake. The purpose of the study is to systematically review the literature on interventions that promote HPV vaccination from 2015 to 2020.
METHODS: We updated a systematic review of interventions to promote HPV vaccine uptake globally. We ran keyword searches in six bibliographic databases. Target audience, design, level of intervention, components and outcomes were abstracted from the full-text articles in Excel databases.
RESULTS: Of the 79 articles, most were conducted in the U.S. (72.2%) and in clinical (40.5%) or school settings (32.9%), and were directed at a single level (76.3%) of the socio-ecological model. Related to the intervention type, most were informational (n = 25, 31.6%) or patient-targeted decision support (n = 23, 29.1%). About 24% were multi-level interventions, with 16 (88.9%) combining two levels. Twenty-seven (33.8%) reported using theory in intervention development. Of those reporting HPV vaccine outcomes, post-intervention vaccine initiation ranged from 5% to 99.2%, while series completion ranged from 6.8% to 93.0%. Facilitators to implementation were the use of patient navigators and user-friendly resources, while barriers included costs, time to implement and difficulties of integrating interventions into the organizational workflow.
CONCLUSIONS: There is a strong need to expand the implementation of HPV-vaccine promotion interventions beyond education alone and at a single level of intervention. Development and evaluation of effective strategies and multi-level interventions may increase the uptake of the HPV vaccine among adolescents and young adults
The serologically defined colon cancer antigen-3 (SDCCAG3) is involved in the regulation of ciliogenesis
A primary cilium is present on most eukaryotic cells and represents a specialized organelle dedicated to signal transduction and mechanosensing. Defects in cilia function are the cause for several human diseases called ciliopathies. The serologically defined colon cancer antigen-3 (SDCCAG3) is a recently described novel endosomal protein mainly localized at early and recycling endosomes and interacting with several components of membrane trafficking pathways. Here we describe localization of SDCCAG3 to the basal body of primary cilia. Furthermore, we demonstrate that decreased expression levels of SDCCAG3 correlate with decreased ciliary length and a reduced percentage of ciliated cells. We show that SDCCAG3 interacts with the intraflagellar transport protein 88 (IFT88), a crucial component of ciliogenesis and intraciliary transport. Mapping experiments revealed that the N-terminus of SDCCAG3 mediates this interaction by binding to a region within IFT88 comprising several tetratricopeptide (TRP) repeats. Finally, we demonstrate that SDCCAG3 is important for ciliary localization of the membrane protein Polycystin-2, a protein playing an important role in the formation of polycystic kidney disease, but not for Rab8 another ciliary protein. Together these data suggest a novel role for SDCCAG3 in ciliogenesis and in localization of cargo to primary cilia
Empowering the people: Development of an HIV peer education model for low literacy rural communities in India
<p>Abstract</p> <p>Background</p> <p>Despite ample evidence that HIV has entered the general population, most HIV awareness programs in India continue to neglect rural areas. Low HIV awareness and high stigma, fueled by low literacy, seasonal migration, gender inequity, spatial dispersion, and cultural taboos pose extra challenges to implement much-needed HIV education programs in rural areas. This paper describes a peer education model developed to educate and empower low-literacy communities in the rural district of Perambalur (Tamil Nadu, India).</p> <p>Methods</p> <p>From January to December 2005, six non-governmental organizations (NGO's) with good community rapport collaborated to build and pilot-test an HIV peer education model for rural communities. The program used participatory methods to train 20 NGO field staff (Outreach Workers), 102 women's self-help group (SHG) leaders, and 52 barbers to become peer educators. Cartoon-based educational materials were developed for low-literacy populations to convey simple, comprehensive messages on HIV transmission, prevention, support and care. In addition, street theatre cultural programs highlighted issues related to HIV and stigma in the community.</p> <p>Results</p> <p>The program is estimated to have reached over 30 000 villagers in the district through 2051 interactive HIV awareness programs and one-on-one communication. Outreach workers (OWs) and peer educators distributed approximately 62 000 educational materials and 69 000 condoms, and also referred approximately 2844 people for services including voluntary counselling and testing (VCT), care and support for HIV, and diagnosis and treatment of sexually-transmitted infections (STI). At least 118 individuals were newly diagnosed as persons living with HIV (PLHIV); 129 PLHIV were referred to the Government Hospital for Thoracic Medicine (in Tambaram) for extra medical support. Focus group discussions indicate that the program was well received in the communities, led to improved health awareness, and also provided the peer educators with increased social status.</p> <p>Conclusion</p> <p>Using established networks (such as community-based organizations already working on empowerment of women) and training women's SHG leaders and barbers as peer educators is an effective and culturally appropriate way to disseminate comprehensive information on HIV/AIDS to low-literacy communities. Similar models for reaching and empowering vulnerable populations should be expanded to other rural areas.</p
A Cross-Sectional Study of HPV Vaccine Acceptability in Gaborone, Botswana
Background
Cervical cancer is the most common cancer among women in Botswana and elsewhere in Sub-Saharan Africa. We sought to examine whether HPV vaccine is acceptable among parents in Botswana, which recently licensed the vaccine to prevent cervical cancer. Methods and Findings
We conducted a cross-sectional survey in 2009, around the time the vaccine was first licensed, with adults recruited in general medicine and HIV clinics in Gaborone, the capital of Botswana. Although only 9% (32/376) of respondents had heard of HPV vaccine prior to the survey, 88% (329/376) said they definitely will have their adolescent daughters receive HPV vaccine. Most respondents would get the vaccine for their daughters at a public or community clinic (42%) or a gynecology or obstetrician\u27s office (39%), and 74% would get it for a daughter if it were available at her school. Respondents were more likely to say that they definitely will get HPV vaccine for their daughters if they had less education (OR = 0.20, 95% CI = 0.07–0.58) or lived more than 30 kilometers from the capital, Gaborone (OR = 2.29, 95% CI = 1.06–4.93). Other correlates of acceptability were expecting to be involved in the decision to get HPV vaccine, thinking the vaccine would be hard to obtain, and perceiving greater severity of HPV-related diseases. Conclusions
HPV vaccination of adolescent girls would be highly acceptable if the vaccine became widely available to the daughters of healthcare seeking parents in Gaborone, Botswana. Potential HPV vaccination campaigns should provide more information about HPV and the vaccine as well as work to minimize barriers
