Can serum autoantibodies be a potential early detection biomarker for breast cancer in women? A diagnostic test accuracy review and meta-analysis.

BACKGROUND: The increasing incidence of breast cancer necessitates the need to explore alternate screening strategies that circumvent the setbacks of conventional techniques especially among population that report earlier age at diagnosis. Serum autoantibodies is one such potential area of interest. However, their ubiquitous presence across cancer types limits its applicability to any one specific type of cancer. This review was therefore carried out to explore and consolidate available evidence on autoantibodies for early detection of breast cancer and to identify those that demonstrated a higher sensitivity. METHODS: A diagnostic test accuracy (DTA) review was carried out to ascertain serum autoantibodies that could be used for early detection of breast cancer among women. All relevant articles that investigated the role of autoantibodies in early detection of breast cancer were included for the review. MEDLINE, Scopus, ProQuest, Ovid SP, and Cochrane Library were searched extensively for eligible studies. Quality of the included studies was assessed using Quality Assessment of Diagnostic Accuracy Studies (QUADAS)-2 tool. RevMan 5.3 was used for exploratory and MetaDTA 2019 for hierarchical analyses. The review helped identify the most frequently investigated autoantibodies and a meta-analysis further consolidated the findings. RESULTS: A total of 53 articles were included for the final analysis that reported over a 100 autoantibodies that were studied for early detection of breast cancer in women. P53, MUC1, HER2, HSP60, P16, Cyclin B1, and c-Myc were the most frequently investigated autoantibodies. Of these P53, MUC1, HER2, and HSP60 exhibited higher summary sensitivity measures. While the individual pooled sensitivity estimates ranged between 10 and 56%, the panel sensitivity values reported across studies were higher with an estimated range of 60-87%. CONCLUSION: Findings from the review indicate a higher sensitivity for an autoantibody panel in comparison to individual assays. A panel comprising of P53, MUC1, HER2, and HSP60 autoantibodies has the potential to be investigated as an early detection biomarker for breast cancer.

Mapping Neonatal Mortality in India: A Closer Look.

INTRODUCTION: Fifty-three percent of Indian under-5 deaths occur during the neonatal age group. Recognizing that there is a lack of illustrated district-level data on neonatal mortality in India, we mapped this to visually highlight districts where neonatal health issues require the most attention. METHODS: District-level estimates of 596 Indian districts were used to generate maps and to illustrate neonatal mortality rates (NMRs), absolute numbers of neonatal deaths; the best and worst performing districts (positive and negative deviants) in each Indian state; the neonatal female/male death ratio; and district lag in NMR reductions. RESULTS: The NMR ranged from 4.3 (Kannur, Kerala) to 65.1 (Datia, Madhya Pradesh), with the mean NMR being 29.8. Almost two-thirds of the districts (n = 380, 63.7%) had NMRs between 20 and 40. The top third of neonatal deaths could be accounted for by just 71 districts of a total of 596. CONCLUSION: There is an urgent need for up-to-date data on district-level neonatal mortality in India.

Effect of Exclusive Breastfeeding on Rotavirus Infection among Children.

OBJECTIVES: To assess, whether exclusive breastfeeding plays a protective role in Rotavirus infection among children under age of five and to estimate whether breastfeeding has an impact on reducing the severity and symptoms among children infected with Rotavirus. METHODS: A systematic search was performed in Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE/PubMEd (from 1980 to present), ScienceDirect (from 1980 to present), OVID (from 1980 to present) and regional database IndMED. All the studies along with the research publications with descriptive, case series, cross sectional, case control and cohort studies (prospective and retrospective) that provided effectiveness of exclusive breastfeeding were considered for this review. Two review authors independently scrutinized the studies and extracted the data. In case of disagreement, the senior reviewer was consulted. RESULTS: Total seven studies qualified for the systematic review in which 6 studies qualified for meta-analysis. Exclusive breastfeeding was found to be effective in prevention of Rotavirus infection and in reducing the risk of Rotavirus infection among children (OR = 0.62, 95 % CI = 0.48-0.81). CONCLUSIONS: This systematic review suggests that there is significant benefit in prevention of Rotavirus diarrhea among children by practicing exclusive breastfeeding throughout first 6 mo of life. Thereby, this study provides next reason to promote exclusive breastfeeding practice among mothers.

An epidemiological overview of child sexual abuse.

Child sexual abuse (CSA) is a universal problem with grave life-long outcomes. The estimates vary widely depending on the country under study, the definitions used, the type of CSA studied, the extent of coverage, and quality of data. This study intended to assess the magnitude and the issues related to CSA. We searched databases such as PubMed, Google scholar, web (newspaper reports), and government websites. The relevant data was extracted from these sources for gathering evidence on CSA and secondary data analysis was done. The prevalence of CSA was found to be high in India as well as throughout the world. CSA is an extensive problem and even the lowest prevalence includes a huge number of victims. It also has various adverse effects on the psychological, physical, behavioral, and interpersonal well-being of the victim. Hence, stringent measures should be taken for the prevention and control of this hidden public health issue.

Effect of prophylactic trochanteric epiphyseodesis in older children with Perthes' disease.

To evaluate the effect of prophylactic epiphyseodesis of the greater trochanter in Perthes' disease, 62 children with unilateral Perthes' disease who underwent trochanteric epiphyseodesis combined with varus osteotomy of the femur during the active stage of the disease (mean age at surgery: 8.4 y) and 20 controls were followed up until skeletal maturity. On radiographs taken at skeletal maturity, the articulo-trochanteric distance, the center-trochanteric distance, the length of the abductor lever arm, the neck-shaft angle, the radius of the femoral head, and the Reimer's migration index of normal and affected hips were measured. The shape of the femoral head was assessed according to the criteria of Mose. The range of hip motion, the strength of hip abduction, and limb lengths were measured and the Trendelenburg sign was elicited. The mean values of articulo-trochanteric distance and center-trochanteric distance were greater and the frequency of a positive Trendelenburg sign was less in children who had undergone trochanteric epiphyseodesis than in children who had no surgery (P<0.01). Trochanteric epiphyseodesis achieved optimal trochanteric growth arrest in 60% of operated children; the procedure was not effective in 30%, and in 10% of children there was overcorrection. Logistic regression analysis showed that the size of the femoral head at healing and the age at surgery were variables that significantly influenced the effectiveness of trochanteric growth arrest. At skeletal maturity, the mean shortening of the affected limb in operated children was 0.44 cm (SD 0.68 cm), whereas that of non-operated children was 0.86 cm (SD 0.78 cm) (P<0.05). The range of motion of the hip was excellent and there were no significant differences in the range of motion among children with optimal correction, under-correction, and overcorrection. A probability curve plotted on the basis of a logistic regression model suggests that effective trochanteric arrest may be achieved in a high proportion of children operated at or before 8.5 years of age and in half the children operated between the age of 8.5 years and 10 years. On the basis of this study, we recommend prophylactic epiphyseodesis of the greater trochanter as a means of minimizing trochanteric overgrowth and resultant Trendelenburg gait in older child with Perthes' disease.
