When life is “difficult”: A comparison of street children's and non-street children's priorities

Research on street children has typically described the phenomenon and examined the risks of street life to healthy development. Thus far, research has not contextualized street children's psychosocial lives by comparing them with non-street children or street children undergoing rehabilitation. The purpose of this study was to assess how the life priorities of Tanzanian street children, former street children and school-going children (n?=?183) differ according to their living environment. The “Importance scale” was designed and validated for this study. It includes 29 four-level Likert items about relationships, activities and family, encompassing two subscales: current well-being (Cronbach's α?=?0.65) and preparing for the future (Cronbach's α?=?0.72). Data were analyzed using analysis of variance and contingency tables to determine group-level differences. Post-hoc Bonferroni tests determined pairwise differences. The analyses demonstrate significant differences in 14 of 29 priorities according to living context. With only three differences, former street children were more similar to school-going children than they were to street children. Street children and school-going children differed on 12 items, while street children and former street children differed on nine items. Street children considered that obtaining good advice from adults, having a dependable place to sleep and having time for enjoyable activities are most important, while former street children and school-going children pointed to education-related ambitions as most important. Findings show that after just 1 year of rehabilitative care, former street children's priorities are more similar to school-going children's, and thus rehabilitative care may be instrumental in enabling children to prioritize preparing for the future. Street children's emphasis on a safe place to sleep and adult support may reflect unmet basic needs. Former street children's high priorities on education and protecting themselves may represent healthy adaptation and a hopeful orientation to the future. High-quality rehabilitation for homeless youth can fulfill essential needs that may promote positive shifts in street children's priorities.     

Serum creatinine to cystatin C ratio is associated with major adverse cardiovascular events in patients with obstructive coronary artery disease

Background & aimsSarcopenia is a clinical syndrome that features muscle atrophy and weakness, and has been associated with cardiovascular events and poor clinical outcomes. Recently, the sarcopenia index (SI) was developed as a simple screening tool based upon the serum creatinine to cystatin C (CysC) ratio. We investigated the association between SI and the prevalence of major adverse cardiovascular events (MACE) in patients with obstructive CAD.Methods & ResultsBetween January 2010 and December 2018, patients with angina pectoris and obstructive CAD requiring coronary artery intervention were enrolled. Serum levels of CysC and other biomarkers were assessed. Patients were divided into two groups according to the SI ([Cr/CysC] x 100). Demographic characteristics and clinical outcomes of the two groups were evaluated. A total of 427 patients (79.6% men, mean age 69.55 ± 12.04 years) were enrolled. Patients with SI < 120 (n = 214, 28%) were older, more likely to be of the female gender, and to have more hypertension and congestive heart failure (all p < 0.05). The prevalence of major adverse cardiovascular events (MACE) composed of myocardial infarction, stroke, and all-cause mortality was higher in patients with lower SI (p = 0.026). After adjusting for potential confounding factors, multivariate Cox regression (hazard ratio 2.08, p = 0.045) and Kaplan–Meier analyses (log-rank p = 0.0371) revealed that lower SI was significantly associated with a higher prevalence of MACE.ConclusionsSerum creatinine to cystatin C ratio (SI) may be a useful surrogate marker to predict the future prevalence of MACE in patients with obstructive CAD.     

Osseous metastases: drugs that enhance bone integrity and prevent adverse skeletal events

More than 400,000 cancer patients in the USA contend with bone metastases on an annual basis. These patients often suffer pain, a decline in quality of life, and a shortened survival. As a result, over the past several years, efforts to enhance bone integrity in patients with osseus metastases have become a major research priority. This review discusses the evolving role of bisphosphonates and their side effects, highlights other pharmacological interventions aimed at enhancing bone integrity, and reviews other pragmatic approaches to prevent worsening pain and fractures, as derived from a single institution case series of patients with problematic rib metastases.

Cardiovascular and cerebrovascular events in patients with intracerebral hemorrhage: Clinical characteristics and long-term predictors

Few studies have examined the long-term prognosis of Chinese patients with intracerebral hemorrhage (ICH). This study assessed the clinical characteristics and predictors of vascular events occurring within 5 years after ICH.We included consecutive patients diagnosed with first-ever ICH between June 2013 and December 2014. Based on follow-up data (collected until December 2019), we used multivariable logistic regression to examine the clinical characteristics and long-term predictors of vascular events (including recurrent ICH, ischemic stroke, and acute coronary syndrome) in patients who survived more than 30 days after ICH.Across the 307 patients in our analysis, the 5-year mortality rate was 28.01%. Within 5 years after ICH, major vascular events were observed in 62 patients (17.82%, 95% CI 13.78–21.82%). We observed high incidence of recurrent ICH (8.91%) and ischemic stroke (10.06%), but low incidence of acute coronary syndrome (1.15%). Most cases of recurrent ICH (80.65%) occurred within 3 years after ICH. Age ≥56 years and history of ischemic stroke or transient ischemic attack (TIA) were identified as predictors of cardiovascular and cerebrovascular events.ICH survivors are at high risk of both cardiovascular and cerebrovascular events, especially older patients (≥56 years) and those who experienced ischemic stroke or TIA prior to their first ICH. Recurrent ICH is more likely to occur within the first three years after first ICH than at later times. Clinicians should monitor patients closely for adverse events, particularly during the first three years after initial ICH.     

Health Status as a Mediating Factor in the Life Change-Academic Performance Relationship

Abstract

This study was designed to determine whether illness during the academic year, when gender and academic readiness are controlled, is the variable accounting for the demonstrated relationship between life change index and subsequent academic performance. A weak though significant inverse association was found between life change and grades: this association persisted even after statistical adjustment for gender, academic readiness, and illness experience. There was no evidence that illness experience mediated the life change-performance relationship. The association was not subject to a threshold effect according to level of life change.     

The Effectiveness and Safety of Platelet-Rich Plasma for Chronic Wounds: A Systematic Review and Meta-analysis

ObjectiveTo evaluate the effectiveness and adverse events of autologous platelet-rich plasma (PRP) in individuals with lower-extremity diabetic ulcers, lower-extremity venous ulcers, and pressure ulcers.Patients and MethodsWe searched multiple databases from database inception to June 11, 2020, for randomized controlled trials and observational studies that compared PRP to any other wound care without PRP in adults with lower-extremity diabetic ulcers, lower-extremity venous ulcers, and pressure ulcers.ResultsWe included 20 randomized controlled trials and five observational studies. Compared with management without PRP, PRP therapy significantly increased complete wound closure in lower-extremity diabetic ulcers (relative risk, 1.20; 95% CI, 1.09 to 1.32, moderate strength of evidence [SOE]), shortened time to complete wound closure, and reduced wound area and depth (low SOE). No significant changes were found in terms of wound infection, amputation, wound recurrence, or hospitalization. In patients with lower-extremity venous ulcers or pressure ulcers, the SOE was insufficient to estimate an effect on critical outcomes, such as complete wound closure or time to complete wound closure. There was no statistically significant difference in adverse events.ConclusionAutologous PRP may increase complete wound closure, shorten healing time, and reduce wound size in individuals with lower-extremity diabetic ulcers. The evidence is insufficient to estimate an effect on wound healing in individuals with lower-extremity venous ulcers or pressure ulcers.Trial RegistrationPROSPERO Identifier: CRD42020172817     

Reducing delirium and cognitive dysfunction after off-pump coronary bypass: A randomized trial

BackgroundNeuropsychiatric complications of surgical coronary revascularization are inconspicuous but frequent and clinically relevant. So far, attempts to reduce their occurrence, such as the introduction of off-pump coronary artery bypass (OPCAB) grafting method, have not brought the desired results. The aim of this trial was to determine whether using any of the 2 selected modifications of OPCAB could decrease the incidence of these undesired sequelae.MethodsIn this single-center, assessor- and patient-blinded, superiority, randomized controlled trial, 192 patients scheduled for elective isolated OPCAB were randomized to 3 parallel arms. The control arm underwent “conventional” OPCAB with vein grafts. The first study arm underwent anaortic OPCAB (ANA) with total arterial revascularization. The second study arm underwent OPCAB with vein grafts using carbon dioxide surgical field flooding (CO₂FF). Outcomes included the incidence of postoperative delirium (PD) and early postoperative cognitive dysfunction (ePOCD).ResultsThe incidence of PD was 35.9% in the control (OPCAB) arm, 32.8% in the CO₂FF arm, and 12.5% in the ANA arm (χ² [2, N = 191] = 10.17; P = .006). Post hoc tests revealed that the incidence of PD in the ANA arm differed from that in the OPCAB arm (odds ratio [OR], 0.26; 95% confidence interval [CI], 0.09-0.68; P = .002). The incidence of ePOCD was 34.4% in the OPCAB arm, 28.1% in the CO₂FF arm, and 9.5% in the ANA arm (χ² [2, N = 191] = 11.58; P = .003). Post hoc tests revealed that the incidence of ePOCD differed between the ANA and OPCAB arms (OR, 0.20; 95% CI, 0.06-0.58; P < .001).ConclusionsPerforming ANA significantly decreases the incidence of PD and ePOCD compared with “conventional” OPCAB with vein grafts, whereas CO₂FF is inconsequential in this regard. These results, which probably reflect decreased delivery of embolic load to the brain in ANA, may have practical applicability in daily practice to improve clinical outcomes.     

Measures of initiation and progression to increased smoking among current menthol compared to non-menthol cigarette smokers based on data from four U.S. government surveys

There are no large-scale, carefully designed cohort studies that provide evidence on whether menthol cigarette use is associated with a differential risk of initiating and/or progressing to increased smoking. However, questions of whether current menthol cigarette smokers initiated smoking at a younger age or are more likely to have transitioned from non-daily to daily cigarette use compared to non-menthol smokers can be addressed using cross-sectional data from U.S. government surveys. Analyses of nationally representative samples of adult and youth smokers indicate that current menthol cigarette use is not associated with an earlier age of having initiated smoking or greater likelihood of being a daily versus non-daily smoker. Some surveys likewise provide information on cigarette type preference (menthol versus non-menthol) among youth at different stages or trajectories of smoking, based on number of days smoked during the past month and/or cigarettes smoked per day. Prevalence of menthol cigarette use does not appear to differ among new, less experienced youth smokers compared to established youth smokers. While there are limitations with regard to inferences that can be drawn from cross-sectional analyses, these data do not suggest any adverse effects for menthol cigarettes on measures of initiation and progression to increased smoking.
