The experience of financial stress among emerging adult cancer survivors.

Objective: The experience of cancer-related financial stress was examined within the developmental context of emerging adulthood.Methodological approach: This study is a secondary analysis of data drawn from two samples of testicular or hematologic cancer survivors. In-depth interviews from 52 emerging adult (EA) cancer survivors, ages 18-29, were coded by combining thematic analysis with an abductive approach.Findings: Emergent themes included some common to most age groups, including worries about medical costs and availability of health insurance, as well as specific age-related concerns, such as fertility preservation. Financial stress appeared to interrupt developmental tasks of emerging adulthood, including completing an education, establishing independence, and managing relationships. Surprisingly, financial stress was experienced as a benefit for some participants.Conclusion: Financial stress affects EA cancer survivors in unique ways. To provide support, health professionals should consider survivors' developmental life stage to understand their financial stress, and ultimately, to improve quality of life

Multi-criteria media mix decision model for advertising multiple product with segment specific and mass media

Judicious media planning decisions are crucial for successful advertising of products. Media planners extensively use mathematical models supplemented with market research and expert opinion to devise the media plans. Media planning models discussed in the literature largely focus on single products with limited studies related to the multi-product media planning. In this paper we propose a media planning model to allocate limited advertising budget among multiple products advertised in a segmented market and determine the number of advertisements to be given in different media. The proposed model is formulated considering both segment specific and mass media vehicles to maximize the total advertising reach for each product. The model also incorporates the cross product effect of advertising of one product on the other. The proposed formulation is a multi-objective linear integer programming model and interactive linear integer goal programming is discussed to solve the model. A real life case study is presented to illustrate the application of the proposed model

Regulation of Serotonin 1A Receptor SUMOylation by SENP2 and PIASxα

Serotonin 1A receptors (5-HT1ARs) are implicated in the control of mood, cognition, and memory and in various neuropsychiatric disorders such as depression and anxiety. As such, understanding the regulation of 5-HT1ARs will inform the development of better treatment approaches. We previously demonstrated 5-HT1ARs are SUMOylated by SUMO1 in the rat brain. Agonist stimulation increased SUMOylation and was further enhanced when combined with 17β-estradiol-3-benzoate (EB), which are treatments that cause the transient and prolonged desensitization of 5-HT1AR signaling, respectively. In the current study, we identified the protein inhibitor of activated STAT (PIAS)xα as the enzyme that facilitates SUMOylation, and SENP2 as the protein that catalyzes the deSUMOylation of 5-HT1ARs. We demonstrated that PIASxα significantly increased in the membrane fraction of rats co-treated with EB and an agonist, compared to either the EB-treated or vehicle-treated groups. The acute treatment with an agonist alone shifted the location of SENP2 from the membrane to the cytoplasmic fraction, but it has little effect on PIASxα. Hence, two separate mechanisms regulate SUMOylation and the activity of 5-HT1ARs by an agonist and EB. The effects of EB on 5-HT1AR SUMOylation and signaling may be related to the higher incidence of mood disorders in women during times with large fluctuations in estrogens. Targeting the SUMOylation of 5-HT1ARs could have important clinical relevance for the therapy for several neuropsychiatric disorders in which 5-HT1ARs are implicated

Predictors of candidemia in pediatric patients (0–12 years) admitted in a tertiary care hospital of Northern India

Background: Bloodstream infections due to Candida species are becoming a major cause of morbidity and mortality in hospitalized patients. The emergence of non-albicans Candida (NACs) species with lesser susceptibility to antifungals has added to the woes of clinicians. Objectives: The objectives of the study were to determine the clinical and laboratory predictors and microbiological profile of candidemia in pediatric patients. Materials and Methods: This is a hospital-based, prospective, and cross-sectional study conducted in the pediatric department of a tertiary care hospital. A total of 250 children aged 0–12 years with risk factors for fungal sepsis were enrolled. Demographic details, clinical, and laboratory parameters were noted and samples were sent for culture. Cultures yielding growth of Candida were included in the study, and antifungal susceptibility performed. Associations were assessed using Chi-square test first and then through logistic regression models. Results: Among the 250 patients with risk factors for fungal sepsis, 47 patients (18.8%) with culture proven candidemia were identified. Predictors of candidemia among neonates were prematurity (<30 weeks), prolonged ventilation (>72 h), and thrombocytopenia. Among pediatric patients, prolonged steroid intake, Candida isolation from sites other than blood and persistent neutropenia, were significantly associated with the candidemia. NAC species were the predominant isolates (78.7%). Conclusion: Candidemia should be suspected in premature neonates requiring prolonged ventilation with unexplained thrombocytopenia. Among pediatric patients, prolonged steroid intake, Candida isolation from sites other than blood and persistent neutropenia are predictors of candidemia

Effect of repeat purchase and dynamic market size on diffusion of an innovative technological consumer product in a segmented market

This study develops diffusion models for technological consumer products under the marketing environment when a product is marketed in a segmented market and observes two distinctive promotional strategies of mass and differentiated promotion; an under explored study area. Mass promotion strategy creates a spectrum effect in market with an aim to create wider product awareness and influence the market size. Whereas the differentiated promotion strategy plays major role in external influence component in the respective segment and target for adoption by the current potential segment. Previous studies on segmented diffusion models assumed only first time purchase and constant market size which may yield underestimated results and fail to give appropriate insight of the diffusion process. The study develops and validates generalized diffusion models for segmented market incorporating the repurchase behaviour of the adopter population and dynamic potential market size considerations. Performance of the proposed models is analysed on real life data for a new product marketed in four segments and compared with the previous study

Complementary feeding at 4 versus 6 months of age for preterm infants born at less than 34 weeks of gestation: a randomised, open-label, multicentre trial

Background Evidence on the optimal time to initiation of complementary feeding in preterm infants is scarce. We examined the effect of initiation of complementary feeding at 4 months versus 6 months of corrected age on weight for age at 12 months corrected age in preterm infants less than 34 weeks of gestation. Methods In this open-label, randomised trial, we enrolled infants born at less than 34 weeks of gestation with no major malformation from three public health facilities in India. Eligible infants were tracked from birth and randomly assigned (1:1) at 4 months corrected age to receive complementary feeding at 4 months corrected age (4 month group), or continuation of milk feeding and initiation of complementary feeding at 6 months corrected age (6 month group), using computer generated randomisation schedule of variable block size, stratified by gestation (30 weeks or less, and 31–33 weeks). Iron supplementation was provided as standard. Participants and the implementation team could not be masked to group assignment, but outcome assessors were masked. Primary outcome was weight for age Z-score at 12 months corrected age (WAZ12) based on WHO Multicentre Growth Reference Study growth standards. Analyses were by intention to treat. The trial is registered with Clinical Trials Registry of India, number CTRI/2012/11/003149. Findings Between March 20, 2013, and April 24, 2015, 403 infants were randomly assigned: 206 to receive complementary feeding from 4 months and 197 to receive complementary feeding from 6 months. 22 infants in the 4 month group (four deaths, two withdrawals, 16 lost to follow-up) and eight infants in the 6 month group (two deaths, six lost to follow-up) were excluded from analysis of primary outcome. There was no difference in WAZ12 between two groups: –1·6 (SD 1·2) in the 4 month group versus –1·6 (SD 1·3) in the 6 month group (mean difference 0·005, 95% CI –0·24 to 0·25; p=0·965). There were more hospital admissions in the 4 month group compared with the 6 month group: 2·5 episodes per 100 infant-months in the 4 month group versus 1·4 episodes per 100 infant-months in the 6 month group (incidence rate ratio 1·8, 95% CI 1·0–3·1, p=0·03). 34 (18%) of 188 infants in the 4 month group required hospital admission, compared with 18 (9%) of 192 infants in the 6 month group. Interpretation Although there was no evidence of effect for the primary endpoint of WAZ12, the higher rate of hospital admission in the 4 month group suggests a recommendation to initiate complementary feeding at 6 months over 4 months of corrected age in infants less than 34 weeks of gestation

Seasonality in carbon chemistry of Cochin backwaters

Seasonality in carbon chemistry of Cochin backwaters, Southern India, was investigated between 2018 and 2019. Dissolved inorganic carbon (DIC) showed strong seasonal variations. Lowest DIC was observed during the Southwest Monsoon (SWM), in conjunction with low salinity in surface waters, suggesting strong freshwater influence. The maximum concentration of partial pressure of carbon dioxide in water (pCO 2w) was recorded from polluted waters of Vembanad Lake (16,000 atm). Excluding the SWM, the inner most stations (freshwater) showed lower pCO 2w levels compared with the outermost (estuarine) ones. With regard to sampling stations, all the environmental properties, except silicate and phosphate, exhibited significant variation, pointing to large spatial heterogeneity across the stations. Redundancy analysis suggested salinity to be inversely related to surface pCO 2w. High pH and low pCO 2w observed in some of the inner most stations indicates role of pH in carbonate speciation. Our study indicates large seasonal fluctuation in biogeochemical parameters and strong heterogeneity between individual stations which therefore necessitates development of local biogeochemical models for better understanding of carbon budget in these waters
