A novel use of biomarkers in the modeling of cancer activity based on the theory of endobiogeny.

INTRODUCTION: Cancer is a complex disorder whose detection and monitoring remains challenging. A biological modeling system, the biology of functions (BoF), claims to be able to evaluate physiologic elements related to carcinogenic activity. A pilot study was undertaken to evaluate the accuracy of the BoF in detecting differences between cancer cases and matched controls. MATERIALS AND METHODS: A retrospective case control study was performed using the BoF analyses of 46 patients with all types of solid and hematgenous cancers, active and inactive (total cases), and 46 controls from a private practice. The standard BoF panel of 17 biomarkers was evaluated. Sixty-two of 150 BoF indices derived from these biomarkers were pre-selected for analysis based on their relationship to cancer physiology. The data was analyzed with the Wilcoxon Signed Ranks Test using SPSS software. RESULTS: Of the 62 indices, 7 were found to be statistically significant in comparing total cancer cases to controls: ßMSH/αMSH, Estrogen Fraction #5, Comparative Genital Androgeny, Thyroid, Genito-thyroid, Catabolism/Anabolism and Pro-inflammatory. CONCLUSIONS: In a small retrospective case control study, statistically significant differences were found between cancer cases and controls in 7 BoF indices. These indices are indicators of physiological conditions consistent with cancer growth. These results warrant further study of this biological modeling system in cancer patients.

Efficacy of fermented milk and whey proteins in Helicobacter pylori eradication: a review.

Helicobacter pylori (H. pylori) eradication is considered a necessary step in the management of peptic ulcer disease, chronic gastritis, gastric adenocarcinoma and mucosa associated lymphoid tissue lymphoma. Standard triple therapy eradication regimens are inconvenient and achieve unpredictable and often poor results. Eradication rates are decreasing over time with increase in antibiotic resistance. Fermented milk and several of its component whey proteins have emerged as candidates for complementary therapy. In this context the current review seeks to summarize the current evidence available on their role in H. pylori eradication. Pertinent narrative/systematic reviews, clinical trials and laboratory studies on individual components including fermented milk, yogurt, whey proteins, lactoferrin, α-lactalbumin (α-LA), glycomacropeptide and immunoglobulin were comprehensively searched and retrieved from Medline, Embase, Scopus, Cochrane Controlled Trials Register and abstracts/proceedings of conferences up to May 2013. A preponderance of the evidence available on fermented milk-based probiotic preparations and bovine lactoferrin suggests a beneficial effect in Helicobacter eradication. Evidence for α-LA and immunoglobulins is promising while that for glycomacropeptide is preliminary and requires substantiation. The magnitude of the potential benefit documented so far is small and the precise clinical settings are ill defined. This restricts the potential use of this group as a complementary therapy in a nutraceutical setting hinging on better patient acceptability/compliance. Further work is necessary to identify the optimal substrate, fermentation process, dose and the ideal clinical setting (prevention/treatment, first line therapy/recurrence, symptomatic/asymptomatic, gastritis/ulcer diseases etc.). The potential of this group in high antibiotic resistance or treatment failure settings presents interesting possibilities and deserves further exploration.

Quality of care, maternal attitude and common physician practices across the socio-economic spectrum: a community survey.

PURPOSE: To evaluate the quality of maternity care, women's perception of the quality of care and factors influencing the same in Delhi. METHOD: Women who delivered a viable live birth in the past 6 months were recruited from South Delhi by a two-stage stratified cluster randomized sampling. In stage 1, two colonies each from three predefined economic strata (high-, middle- or low-income areas) were selected by simple-random sampling. In stage 2, a sequential house-to-house survey was conducted in each selected colony. The information was collected by interview and review of medical records. RESULTS: A total of 5,279 houses were screened to recruit 249 subjects. Several disparities were notable. 25.2 and 14.8% of the women from middle- and lower-income areas delivered by cesarean section, while the rate was 53.6% in the higher-income areas. In women from lower-income areas urine testing was not done in 76.9% and blood sugar was not tested in 18.2%, while in high-income areas 44.6% had > or =10 antenatal visits and 87.8% had > or =3 ultrasounds. Of the women who experienced labor only 11% received support from a friend or family member, 4.4% received any medicine/measures for pain relief, 44.3% were allowed to walk and 14.6% were catheterized. CONCLUSION: Health care providers are unable to meet national minimal care standards in poorer areas, while over investigation and over intervention appear prevalent in higher-income areas. This warrants a more representative evaluation to enable more equitable and evidence-based practice.

Direct cost of maternity-care services in South Delhi: a community survey.

The study was conducted to estimate the direct maternity-care expense for women who recently delivered in South Delhi and to explore its sociodemographic associations. A survey was conducted using the two-stage cluster-randomized sampling technique. Two colonies each from high-, middle- and low-income areas were selected by simple random sampling, followed by a house-to-house survey in each selected colony. Information was collected by recall of healthcare expenses for mother and child. In total, 249 subjects (of 282 eligible) were recruited. The mean expense for a normal vaginal delivery (n=182) was US$ 370.7, being much higher in a private hospital (US$ 1,035) compared to a government hospital (US$ 61.1) or a delivery in the home (US$ 55.3). Expenses for a caesarean delivery (n=67) were higher (US$ 1,331.1). Expenses for the lowest-income groups were approximately 10% of their annual family income at government facilities and approximately 26% at private hospitals. The direct maternity expense is high for large subsections of the population.

Effect of fermented milk-based probiotic preparations on Helicobacter pylori eradication: a systematic review and meta-analysis of randomized-controlled trials.

OBJECTIVE: To evaluate the effect of fermented milk-based probiotic preparations on Helicobacter pylori eradication. DESIGN: Systematic review of randomized controlled trials. DATA SOURCES: Electronic databases and hand search of reviews, bibliographies of books and abstracts and proceedings of international conferences. REVIEW METHODS: Included trials had to be randomized or quasi-randomized and controlled, using fermented milk-based probiotics in the intervention group, treating Helicobacter-infected patients and evaluating improvement or eradication of H. pylori as an outcome. RESULTS: The search identified 10 eligible randomized controlled trials. Data were available for 963 patients, of whom 498 were in the treatment group and 465 in the control group. The pooled odds ratio (studies n=9) for eradication by intention-to-treat analysis in the treatment versus control group was 1.91 (1.38-2.67; P<0.0001) using the fixed effects model; test for heterogeneity (Cochran's Q=5.44; P=0.488). The pooled risk difference was 0.10 (95% CI 0.05-0.15; P<0.0001) by the fixed effects model (Cochran's Q=13.41; P=0.144). The pooled odds ratio for the number of patients with any adverse effect was 0.51 (95% CI 0.10-2.57; P=0.41; random effects model; heterogeneity by Cochran's Q=68.5; P<0.0001). CONCLUSION: Fermented milk-based probiotic preparations improve H. pylori eradication rates by approximately 5-15%, whereas the effect on adverse effects is heterogeneous.

An exploratory study to evaluate the utility of an adapted Mother Generated Index (MGI) in assessment of postpartum quality of life in India.

BACKGROUND: Given the postulated advantages of mother generated index (MGI) in incorporating the patients' viewpoint and in the absence of a validated India specific postpartum quality of life assessment tool we proposed to evaluate the utility of an adapted Mother-Generated-Index in assessing postpartum quality of life (PQOL) in India. METHODS: The study was integrated into a community survey conducted in one district of Delhi by two-stage cluster randomized sampling to recruit women who delivered in the last 6 months. PQOL was assessed using MGI. Physical morbidity and Edinburgh- postnatal-depression-scale (EPDS) were also recorded for validation purposes. RESULTS: All subjects (249 of 282 eligible) participating in the survey were approached for the MGI evaluation which could be administered to 195 subjects due to inadequate comprehension or refusal of consent. A trend towards lower scores in lower socioeconomic stratum was observed (Primary index score-2.9, 3.7 and 4.0 in lower, middle and higher strata; Secondary Index Score-2.6, 3.2 and 3.0 in lower, middle and higher strata). 59.4% mothers had scores suggestive of possible depression (EPDS; n = 172). Primary index score had a good correlation with validator scores like EPDS (p = 0.024) and number of physical problems (p = 0.022) while the secondary index score was only associated with EPDS score (p = 0.020). CONCLUSION: The study documents that the MGI, with its inherent advantages, is a potentially useful tool for postpartum quality of life evaluation in India especially in the absence of an alternative pre-validated tool.
