Significant Association of Urinary Toxic Metals and Autism-Related Symptoms—A Nonlinear Statistical Analysis with Cross Validation
No full textA number of previous studies examined a possible association of toxic metals and autism, and over half of those studies suggest that toxic metal levels are different in individuals with Autism Spectrum Disorders (ASD). Additionally, several studies found that those levels correlate with the severity of ASD.In order to further investigate these points, this paper performs the most detailed statistical analysis to date of a data set in this field. First morning urine samples were collected from 67 children and adults with ASD and 50 neurotypical controls of similar age and gender. The samples were analyzed to determine the levels of 10 urinary toxic metals (UTM). Autism-related symptoms were assessed with eleven behavioral measures. Statistical analysis was used to distinguish participants on the ASD spectrum and neurotypical participants based upon the UTM data alone. The analysis also included examining the association of autism severity with toxic metal excretion data using linear and nonlinear analysis. “Leave-one-out” cross-validation was used to ensure statistical independence of results. values ranging from 0.12–0.48

No full textComparative study of extrapolative factors linked with oxidative injury and anti-inflammatory status in chronic kidney disease patients experiencing cardiovascular distress
No full textChronic kidney disease (CKD) is a group of heterogeneous abnormalities affecting the function and structure of the kidney and mostly further proceeds to cardiovascular damage prior to end stage renal disease (ESRD). The oxidative insult and inflammatory mediators have some undefined role in CKD and cardiovascular complications. It is therefore, aimed at to pin point the predictive factors in the development of cardiovascular disorder in patients with chronic kidney disease.Fifty patients of CKD experiencing cardiovascular distress and twenty normal individuals having same age and sex acted as control during these observations. Blood samples (Each 5 ml) were drawn and subjected to centrifugation for 10–15 minutes to separate the serum at 4000-5000rpm. The levels of MDA, GSH, SOD, CAT, VIT C, VIT E, IL-1, TNF-alpha, nitric oxide (NO) and advanced oxidation protein products (AOPPs) were estimated and analyzed.MDA) as1.25±0.07 nmol/ml was observed in CKD patients viz-a-viz relevant control. However, the serum SOD, catalase (CAT) and GSH levels in the same patients registered a significant decline as evident from respective figures 0.07±0.002 μg/dl, 1.22±0.012 μmol/mol, and 3.25±1.05 μg/dl. The control for these was observed as0.99±0.06 μg/dl, 3.19±0.05 μmol/mol, and 8.64±0.03 μg/dL. On the other hand, the IL-1 levels in the CKD patients found quite higher (402.5±18.26 pg/ml). This clearly points to substantial increase in oxidative insult and reduced NO levels leading to the renal and cardiovascular damage.Observations support the fact that the decrease in anti-oxidative capacity accompanied by higher inflammatory mediators in CKD is indicative of oxidative stress, consequently leading to CKD progression, in all probability to cardiovascular insult. The outcome reiterates that strategies be designed afresh to contain CKD progression to cardiovascular complications and ESRD. One way could be to focus on early detection of stress related to the disease. It requires analyzing the factors related to stress, such as the one reported here. Linking these factors with the symptoms could be a crucial step forward. And further, the disease could be monitored in a more disciplined manner
Fostering better policy adoption and inter-disciplinary communication in healthcare: A qualitative analysis of practicing physicians’ common interests
No full textIn response to limited physician adoption of various healthcare initiatives, we sought to propose and assess a novel approach to policy development where one first characterizes diverse physician groups’ common interests, using a medical student and constructivist grounded theory.In 6 months, a medical student completed 36 semi-structured interviews with interventional radiologists, gynecologists, and vascular surgeons that were systematically analyzed according to constructivist grounded theory to identifying common themes. Common drivers of clinical decision making and professional values across 3 distinct specialty groups were derived from physicians’ descriptions of their clinical decision making, stories, and concerns.Common drivers of clinical decision making included patient preference/benefit, experience, reimbursement, busyness/volume, and referral networks. Common values included honesty, trustworthiness, loyalty, humble service, compassion and perseverance, and practical wisdom. Although personal gains were perceived as important interests, such values were easily sacrificed for the good of patients or other non-financial interests. This balance was largely dependent on the incentives and security provided by physicians’ environments.Using a medical student interviewer and constructivist grounded theory is a feasible means of collecting rich qualitative data to guide policy development. Healthcare administrators and medical educators should consider incorporating this methodology early in policy development to anticipate how value differences between physician groups will influence their acceptance of policies and other broad healthcare initiatives

No full textHIV-infected people may present with co-infections, comorbidities, and side effects associated with antiretroviral therapy. This study explored the prevalence of comorbid health problems and determined the extent of the use of traditional medicine for treatment of co-infections, comorbidities of HIV infection and side effects.A cross sectional study, using researcher-administered questionnaires, was carried out among HIV-infected patients in eight public sector healthcare facilities in KwaZulu-Natal between April and October 1024. Self-reports of comorbidities, co-infections and side effects were analyzed with respect to factors such as age, gender, race, and health care seeking behavior including the use of traditional medicine. Cross-tabulations were conducted to test the association between factors and the use of traditional medicine, using Pearson chi-squared (χ2) test. Simple and multiple logistic regression models tested the association of the use of traditional medicine with age, gender, race, side effects and comorbidities. Odds ratios with 95% confidence intervals were estimated. Missing values were handled, defined and treated as missing values in the final analysis.Overall, 29.5% (n = 516) of the survey participants reported having other comorbidities and or co-infections besides their HIV condition. Same participants reported two or more comorbidities. Almost forty percent of participants (208/531, 39.17%) reported having hypertension as the most noninfectious comorbidity while 21.65% of participants (115/531) had tuberculosis accounting for the most infectious comorbidity. Almost eight percent of participants (142/1748, 8.12%) reported using traditional medicine after starting with cART. Sixty out of 142 participants (60/142, 42.25%) on cART resorted to the use of traditional medicine for the management of comorbidities and or co-infections of their HIV infection. Overall, 311 out of 1748 participants (17.80%) complained of ARVs related side-effects. Forty-five percent of those with side-effects (141/311, 45.34%) reported taking various types of medicines for treating side-effects, with 90.07% of them (127/141) using medicines prescribed by biomedically trained doctors or by pharmacy personnel as over-the -counter medicines, p <0. 001. Very few participants (14/141, 9.93%) resorted to the use of traditional medicine for treating side effects associated with antiretroviral therapy with no significant difference (p=0.293). In a multiple logistic regression, after adjusting for age, gender, race and side-effects due to antiretroviral therapy, odds for using traditional medicine were almost two times higher [odds ratio = 1.884, 95% Confidence Interval 1.317–2.695] with those participants having comorbidities and co-infections, with a significant difference p-value< 0.001.Comorbidities, co-infections and side effects are prevalent among HIV-infected patients attending public sector healthcare facilities. Odds of using traditional medicine were almost two times higher and significantly associated with the presence of comorbidities and co-infections than for other factors. The presence of such comorbid health problems does not explain the increased use of traditional medicine among HIV-infected patients on antiretroviral therapy. Findings from this study should be interpreted cautiously as they cannot be generalized to the entire population of HIV-infected patients in KwaZulu-Natal. Studies on safety and efficacy of herbal traditional medicines are needed for beneficiation of the minority of patients who still resort to them for co-treatment with combination antiretroviral therapy
