Actual and perceived social isolation are both associated with increased risk for early mortality. In this meta-analytic review, our objective is to establish the overall and relative magnitude of social isolation and loneliness and to examine possible moderators. We conducted a literature search of studies (January 1980 to February 2014) using MEDLINE, CINAHL, PsycINFO, Social Work Abstracts, and Google Scholar. The included studies provided quantitative data on mortality as affected by loneliness, social isolation, or living alone. Across studies in which several possible confounds were statistically controlled for, the weighted average effect sizes were as follows: social isolation odds ratio (OR) = 1.29, loneliness OR = 1.26, and living alone OR = 1.32, corresponding to an average of 29%, 26%, and 32% increased likelihood of mortality, respectively. We found no differences between measures of objective and subjective social isolation. Results remain consistent across gender, length of follow-up, and world region, but initial health status has an influence on the findings. Results also differ across participant age, with social deficits being more predictive of death in samples with an average age younger than 65 years. Overall, the influence of both objective and subjective social isolation on risk for mortality is comparable with well-established risk factors for mortality.

With the use of strict screening criteria, a substantial number of febrile one-to-two-month-old infants can be cared for safely as outpatients and without antibiotics.

A substantial proportion (10.3%) of older febrile infants has SBI. In the postpneumococcal vaccine era, only 1 infant had pneumococcal disease; bacteremia was noted in 0.9%. Bacteruria is commonly associated with fever in this age range. Infants older than 8 weeks remain at risk for bacteremia and bacteruria, regardless of positive DFA or other apparent source of fever. CRP is a better indicator than white blood cell count, but no single ideal indicator of SBI was identified for this age group.

ABSTRACT. Objectives. To identify the causative agents, presenting signs and symptoms, and course of disease in children diagnosed with anaphylaxis.Design. Five-year retrospective chart review. Setting. Urban children's hospital pediatric emergency department, operating suite, and inpatient units.Participants. Fifty-five cases of anaphylaxis in 50 patients 1 to 19 years of age.Interventions. None. Results. The most common inciting agents in this population were latex (27%), food (25%), drugs (16%), and venoms (15%). Thirty-two cases (58%) occurred outside of the hospital, including 3 of 11 severe cases. Nineteen (35%) had histories of prior allergy to the causative agent. Most agent exposures were intravenous (38%), oral (27%), or dermal (20%). The most common systems involved were respiratory (93%), skin (93%), cardiovascular (26%), and neurologic (26%). Features distinguishing the 11 patients requiring intensive care included latex agents (45%), nonenteral route of exposure (91%), and presence of cardiovascular symptoms (45%). Of the 17 patients with known past anaphylaxis, only 5 had epinephrine self-administration devices available, and 3 had used them.Conclusions.

The Philadelphia protocol for outpatient management without antibiotics of FIs at low risk for SBI remains practical, reliable, and safe. Because breaches do occur, physicians must carefully scrutinize protocol compliance, especially with regard to the complete blood count and urinalysis.
