Existing empirical literature on the prolonged or cumulative consequences of exposure to the stresses of caregiving is reviewed. Specific goals are to identify psychiatric and physical morbidity effects, report the magnitude of those effects, evaluate research and analytic methods used to assess morbidity, and make recommendations for future research. Overall, the literature indicates increases in self-report psychiatric symptomatology and increases in psychiatric illness among most caregivers when compared to population norms or appropriate control groups. However, there is little information on the population prevalence or incidence of clinically significant psychiatric conditions attributable to caregiving. Studies of physical health effects as assessed by self-report, health care utilization, and immune function are less conclusive but, nevertheless, suggest increased vulnerability to physical illness among caregivers. We conclude with a discussion of why morbidity effects are difficult to obtain in caregiver studies and with recommendations for future research.
Objective
To determine association of anemia and RBC transfusions with NEC in preterm infants.
Study Design
111 preterm infants with NEC ≥ Stage 2a were compared with 222 matched controls. 28 clinical variables, including hematocrit and RBC transfusions were recorded. Propensity scores and multivariate logistic regression models were created to examine effects on the risk of NEC.
Results
Controlling for other factors, lower hematocrit was associated with increased odds of NEC [OR 1.10, p =0.01]. RBC transfusion has a temporal relationship with NEC onset. Transfusion within 24h (OR=7.60, p=0.001) and 48h (OR=5.55, p=0.001) has a higher odds of developing NEC but this association is not significant by 96h (OR= 2.13, p =0.07), post transfusion
Conclusions
Anemia may increase the risk of developing NEC in preterm infants. RBC transfusions are temporally related to NEC. Prospective studies are needed to better evaluate the potential influence of transfusions on the development of NEC.
Histologic chorioamnionitis increases major perinatal morbidity through its association with preterm birth and is independently associated with neonatal death. In the presence of histologic chorioamnionitis, antenatal steroids significantly decreased the incidence of RDS, intraventricular hemorrhage and periventricular leukomalacia, major brain lesions, and neonatal mortality, without increasing neonatal sepsis.
Trend monitoring of peritransfusion VSVs, especially blood pressures, may aid in the bedside recognition of TACO/FC-STRs. A subset of these patients may also present with febrile and/or inflammatory signs and symptoms.
Objective To describe the prevalence of and risk factors for experiencing "phantom vibrations," the sensory hallucination sometimes experienced by people carrying pagers or cell phones when the device is not vibrating. Design Cross sectional survey. Setting Academic medical centre. Participants 176 medical staff who responded to questionnaire (76% of the 232 people invited). Measurements Electronic survey consisting of 17 questions about demographics, device use, phantom vibrations experienced, and attempts to stop them. Results Of the 169 participants who answered the question, 115 (68%, 95% confidence interval 61% to 75%) reported having experienced phantom vibrations. Most (68/112) who experienced phantom vibrations did so after carrying the device between 1 month and 1 year, and 13% experienced them daily. Four factors were independently associated with phantom vibrations: occupation (resident v attending physician, prevalence ratio 1.47, 95% confidence interval 1.10 to 1.97), device location (breast pocket v belt, prevalence ratio 1.66, 1.29 to 2.14), hours carried (per 6 hour increment, prevalence ratio 1.30, 1.07 to 1.58), and more frequent use in vibrate mode (per frequency category, prevalence ratio 1.18, 1.03 to 1.34). Of those who experienced phantom vibrations, 43 (39%, 30% to 48%) were able to stop them. Strategies for stopping phantom vibrations included taking the device off vibrate mode, changing the location of the device, and using a different device (success rates 75% v 63% v 50%, respectively, P=0.217). However, 39% (30% to 49%) of respondents did not attempt any strategies. Conclusions Phantom vibration syndrome is common among those who use electronic devices.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
