Predictors of posttraumatic stress symptom trajectories in parents of children exposed to motor vehicle collisions

Following child trauma, parents are at risk of developing posttraumatic stress disorder (PTSD), either owing to their direct involvement or from hearing of their child's involvement. Despite the potential impact of a parent's development of PTSD on both the parent and child, little is known about what may place a parent at increased risk.   METHOD: PTSD symptoms were assessed ≤4 weeks, 6 months, and 3 years post-trauma, along with a range of potential risk factors, in a sample of parents of 2-10-year-old children who were involved in a motor vehicle collision.   RESULTS AND CONCLUSIONS: Two symptom trajectories were identified: Those parents whose symptoms remained low across all time points and those whose symptoms remained elevated at 6 months post-trauma and declined by 3 years. Subjective threat, thought suppression, and maladaptive cognitions about damage to the child were identified as key predictors of poorer outcomes

Objective Following child trauma, parents are at risk of developing posttraumatic stress disorder (PTSD), either owing to their direct involvement or from hearing of their child’s involvement. Despite the potential impact of a parent’s development of PTSD on both the parent and child, little is known about what may place a parent at increased risk. Method PTSD symptoms were assessed ≤4 weeks, 6 months, and 3 years post-trauma, along with a range of potential risk factors, in a sample of parents of 2–10-year-old children who were involved in a motor vehicle collision. Results and Conclusions Two symptom trajectories were identified: Those parents whose symptoms remained low across all time points and those whose symptoms remained elevated at 6 months post-trauma and declined by 3 years.

Prevalence, Patterns of Treatment, and Control of Hypertension in Predialysis Patients with Chronic Kidney Disease

&lt;b&gt;&lt;i&gt;Background/Aims:&lt;/i&gt;&lt;/b&gt; Data on the prevalence, treatment and control of hypertension in patients with advanced chronic kidney disease (CKD) are limited. This study aimed to examine the above factors in a cohort of predialysis patients. &lt;b&gt;&lt;i&gt;Methods:&lt;/i&gt;&lt;/b&gt; During a period of 4 months, we recorded information on blood pressure (BP), comorbidities, medications and related parameters of patients followed up in the Low-Clearance Clinic of our Department. Control rates of hypertension were calculated at two thresholds: &lt;130/80 and &lt;140/90 mm Hg. Univariate and multiple linear regression analyses were employed to assess factors associated with BP control. &lt;b&gt;&lt;i&gt;Results:&lt;/i&gt;&lt;/b&gt; In the population studied [n = 238, males 58.4%, age 66.21 ± 4.2 years (mean ± SD), estimated glomerular filtration rate 14.5 ± 4.8 ml/min/1.73 m&lt;sup&gt;2&lt;/sup&gt;], the prevalence of hypertension was 95.0%. Treatment rate among hypertensives was at 99.1%. On average, 3.04 ± 1.32 antihypertensive drugs were used, ranging from 1 to 7 agents. BP control rates at the &lt;130/80 and &lt;140/90 mm Hg thresholds were 26.5% and 48.2%, respectively. The systolic goal was achieved in 31.0% and 50.4%, whereas the diastolic goal was achieved in 67.7% and 91.2% of patients, respectively. In multivariate analysis, only black race was independently and inversely related with hypertension control (β = –0.187, p = 0.030). No specific antihypertensive class showed independent associations with control. &lt;b&gt;&lt;i&gt;Conclusions:&lt;/i&gt;&lt;/b&gt; Hypertension is highly prevalent in predialysis CKD patients. An almost universal treatment, employing a multi-agent regime, can help towards improved rates of control. Systolic BP is the main barrier to successful control and black race is associated with poorer control rates.</jats:p

Prevalence and factors associated with hyperkalemia in predialysis patients followed in a low-clearance clinic

BACKGROUND AND OBJECTIVES: Recent studies evaluated the prevalence of hyperkalemia and related risk factors in patients with CKD of various stages, but there is limited relevant information in predialysis patients. This study aimed to examine the prevalence and factors associated with hyperkalemia in the structured environment of a low-clearance clinic. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: In a cross-sectional fashion over a prespecified period of 4 months, information on serum potassium and relevant laboratory variables, comorbidities, medications, and dietician input in patients with advanced CKD under follow-up in the low-clearance clinic of our department was recorded. Univariate and multiple logistic regression analyses were used to identify factors associated with serum potassium≥5.5 meq/L. RESULTS: The study population consisted of 238 patients aged 66.2±4.2 years with estimated GFR of 14.5±4.8 ml/min per 1.73 m(2). The prevalence of hyperkalemia. defined as potassium>5.0, ≥5.5, and ≥6.0 meq/L., was at 54.2%, 31.5%, and 8.4%, respectively. In univariate comparisons, patients with potassium≥5.5 meq/L had significantly higher urea and lower estimated GFR and serum bicarbonate; also, they were more often using sodium bicarbonate and had received potassium education and attempts for dietary potassium lowering. Use of angiotensin-converting enzyme inhibitors or angiotensin receptor blockers was not associated with hyperkalemia. In multivariate analyses, estimated GFR<15 ml/min per 1.73 m(2) and sodium bicarbonate use were independently associated with hyperkalemia. CONCLUSIONS: The prevalence of hyperkalemia in predialysis patients with CKD is high. Even at this range of renal function, low estimated GFR seems to be the most important factor associated with hyperkalemia among the wide range of demographic, clinical, and laboratory characteristics studied
