Factors Influencing the Sex Ratio at Birth in India: A New Analysis based on Births Occurring between 2005 and 2016

Previous research on sex ratio at birth (SRB) in India has largely relied on macro‐analysis of census data that do not contain the breadth of factors needed to explain patterns in SRB. Additionally, no previous research has examined the differentiation of factors associated with SRB across birth orders, a key determinant in societies affected by son preference. This study aims to fill these gaps using micro‐data related to 553,461 births occurring between 2005 and 2016 collected as part of the 2015–2016 National Family Health Survey. Analyses used multivariable logistic regressions stratified by birth order to examine associations with SRB at the national level. The SRB at birth order 1 was outside the biological normal limit, and generally increased with birth order. First births in households with wealth in the middle and richest quintiles, with mothers who desired a higher ideal number of sons than daughters, and in lower fertility communities had a higher probability of being male. Most SRB correlates were visible at birth orders 3 or higher. Programs and policies designed to address India's male‐skewed SRB must consider the diverse factors that influence SRB, particularly for higher order births.

The Ki-67 protein interacts with members of the heterochromatin protein 1 (HP1) family: a potential role in the regulation of higher-order chromatin structure.

The expression of the nuclear protein Ki-67 (pKi-67) is strictly correlated with cell proliferation. Because of this, anti-Ki-67 antibodies can be used as operational markers to estimate the growth fraction of human neoplasia in situ. For a variety of tumours, the assessment of pKi-67 expression has repeatedly been proven to be of prognostic value for survival and tumour recurrence, but no cellular function has yet been ascribed to the Ki-67 protein. This study shows that a C-terminal domain of pKi-67 (Kon21) is able to bind to all three members of the mammalian heterochromatin protein 1 (HP1) family in vitro and in vivo. This interaction can be manipulated in living cells, as evidenced by ectopic expression of GFP-tagged HP1 proteins in HeLa cells, which results in a dramatic relocalization of endogenous pKi-67. Taken together, the data presented in this study suggest a role for pKi-67 in the control of higher-order chromatin structure.     

Expanding clinical role of unique class III antiarrhythmic effects of sotalol

The concept of controlling cardiac arrhythmias by prolonging repolarization was first exemplified in the electrophysiologic properties of sotalol. It has since been shown to be a property shared by an increasing number of compounds. Sotalol has an additional propensity for blocking beta receptors; therefore, its net effects in controlling arrhythmias result from its beta-blocking actions as well as lengthening the refractory period of cardiac muscle. The properties of amiodarone, another class III agent, are even more complex. The potency of these 2 agents must therefore be distinguished from the so-called "pure" class III agents, which may exhibit a more restricted spectrum of action. Available data indicate that prolonged QT interval (the correlate of prolonged cardiac repolarization) merely provides the substrate for antifibrillatory and proarrhythmic actions relative to the absence or presence of associated pharmacologic properties of the compounds or to the clinical setting in which these compounds are used. Thus, class III agents might be expected to exhibit a variable spectrum of efficacy as antifibrillatory drugs with an equally variable incidence of torsades de pointes and so induce a proarrhythmic effect. An understanding of the mechanisms underlying these differences, especially at a cellular level, may provide the basis for the development of newer, clinically relevant antiarrhythmic and antifibrillatory compounds.     

Should neonates with specific "risk factors" be admitted to the special care nursery?

Existing criteria for admission of newborns to the special care nursery, Sarawak General Hospital, resulted in the admission of many neonates with certain risk factors ("at risk" neonates). To test whether such babies could be safely and better cared for in postnatal wards, 392 of these babies were randomly allocated into two groups. One group of 196 was admitted to the special care nursery and the other group of 196 was cared for with their mothers in the postnatal wards. The two groups were compared for mortality, morbidity and breastfeeding. There was no significant difference in mortality and morbidity between the two groups. While in hospital a larger proportion of babies cared for in postnatal wards were breastfed, compared to babies admitted to the special care nursery. In addition, they initiated their breastfeeding earlier. Babies with these risk factors should therefore be cared for with their mothers in the postnatal wards.     

A multifacet typology of patient satisfaction with a hospital stay

The author views patient satisfaction after a hospital visit as a combination of several different and distinct evaluations. Patients are posited to form satisfaction judgments concurrently for each of the individual "objects" (e.g., physician, insurance provider) comprising the health care system. With patient data from four geographic areas, the author examines this multifacet view empirically and uses it to derive a typology of patient satisfaction. The study results suggest two broad groups of patients, the "satisfieds" and the "dissatisfieds." Finally, the author delineates the behavioral and demographic characteristics that discriminate between the two groups. Implications for health care researchers, practitioners, and public policy officials are presented.     

Differentiation of ischemic from non-ischemic central retinal vein occlusion during the early acute phase

We investigated prospectively in 128 patients (140 eyes) the role of six routine clinical tests in the differentiation of ischemic central retinal vein occlusion (CRVO) from non-ischemic CRVO during its early acute phase. There were fourfunctional tests [visual acuity, visual fields, relative afferent pupillary defect (RAPID), electroretinography (ERG)] and twomorphologic tests (ophthalmoscopy and fluorescein fundus angiography). We found that none of the six tests had 100% sensitivity and specificity in such a differentiation during the early, acute phase, so that no one test can be considered a gold standard; however, combined information from all six is almost always reliable. Overall, the four functional tests proved far superior to the two morphologic tests in differentiating ischemic from non-ischemic CRVO: RAPID was most reliable in uniocular CRVO (with a normal fellow eye), followed closely by ERG in all cases; combined information from RAPID and ERG differentiated 97% of cases; perimetry was the next most reliable, followed by visual acuity. The two morphologic tests performed worst; fluorescein angiography provided either no information at all on retinal capillary nonperfusion (in at least one-third of the eyes during the early, acute phase) because of multiple limitations, or sometimes provided misleading information. Ophthalmoscopic appearance is the least reliable, most misleading parameter.A preliminary summary of this was presented at the Macula Society Meeting, Cannes, France (June, 1987) and at the XVIth Meeting of the Club Jules Gonin, Bruges, Belgium, 4–8 September 1988. This investigation was supported by grant EY-1151 from the National Institutes of Health and, in part, by unrestricted grants from Research to Prevent Blindness, Inc., and from Alcon Research Institute
