RESUMO

Purpose: No recommendations exist for routine reproductive intention screening in primary care. The objective of this systematic review is to assess the effect of reproductive intention screening in primary care on reproductive health outcomes (PROSPERO CRD42015019726). Methods: We performed a systematic search in Ovid Medline, PubMed, CINAHL, Embase, CDR/DARE databases, Web of Science, ISRCTN registry, Clinicaltrials.gov and Cochrane Library. Studies published in English between 2000 and 2017 and whose population was patients of reproductive age (15-49) were included. Studies without a comparison group were excluded. Two independent reviewers assessed eligibility, study quality and abstracted data. Results: Of 24 780 titles and/or abstracts reviewed, nine studies met inclusion criteria: four randomized controlled trials (RCTs) and five observational studies. Two RCTs and one quasi-experimental cohort study showed a statistically significant increase in knowledge related to healthier pregnancy, such as the benefits of folic acid supplementation, and increased risk profiles for those with chronic conditions. Among studies measuring contraceptive use, only one cohort study showed any increase while the RCT and retrospective cohort did not show a statistically significant effect. Neither of the two RCTs that assessed the provision of contraception by primary care providers for those not desiring pregnancy found increased access to contraception, although one found increased documentation of contraception in electronic medical records. Acceptability of reproductive intention screening was measured in seven studies, and participant satisfaction was high in all seven studies. Conclusions: More research is needed to determine whether routine inclusion of reproductive intention screening in primary care is warranted.

RESUMO

Atypical hemolytic uremic syndrome (aHUS) is caused by alternative complement pathway dysregulation, leading to systemic thrombotic microangiopathy (TMA) and severe end-organ damage. Based on 2 prospective studies in mostly adults and retrospective data in children, eculizumab, a terminal complement inhibitor, is approved for aHUS treatment. Here we prospectively evaluated efficacy and safety of weight-based dosing of eculizumab in eligible pediatric patients with aHUS in an open-label phase II study. The primary end point was complete TMA response by 26 weeks. Twenty-two patients (aged 5 months-17 years) were treated; 16 were newly diagnosed, 12 had no prior plasma exchange/infusion during current TMA symptomatology, 11 received baseline dialysis and 2 had prior renal transplants. By week 26, 14 achieved a complete TMA response, 18 achieved hematologic normalization, and 16 had 25% or better improvement in serum creatinine. Plasma exchange/infusion was discontinued in all, and 9 of the 11 patients who required dialysis at baseline discontinued, whereas none initiated new dialysis. Eculizumab was well tolerated; no deaths or meningococcal infections occurred. Bone marrow failure, wrist fracture, and acute respiratory failure were reported as unrelated severe adverse events. Thus, our findings establish the efficacy and safety of eculizumab for pediatric patients with aHUS and are consistent with proposed immediate eculizumab initiation following diagnosis in children.

RESUMO

AIM: We aimed to evaluate a young adult renal clinic (YAC) intervention that included a multidisciplinary clinic and social programme. METHODS: Semi-structured interviews and surveys (Kidney Disease Quality of Life (KDQOL)-36, Time Trade-Off (TTO) and Morisky 8-Item Medication Adherence Questionnaire) were conducted with 15 patients aged 18 to 26 years with chronic kidney disease Stages 1-5, 5D and 5T before and after they attended two YACs. RESULTS: We identified six themes: gaining confidence (encouraging self-expression, exchanging experiential knowledge, helping others, positive reflection and optimism); social connectedness; appreciating a welcoming environment; competing priorities; avoiding the sick identity; and relational boundaries. There were no significant improvements in the overall utility-based quality of life (QOL) scores (TTO: 0.72 (standard deviation (SD): 0.34) and 0.76 (SD: 0.30), P = 0.70) and the proportion of participants achieving medium to high medication adherence (n = 7, 46.7% vs n = 8, 53.3%, P = 0.72). Similar findings were observed for KDQOL domains. CONCLUSION: The impact of the YAC on QOL and adherence is unclear. However, patients can develop coping mechanisms and derive psychosocial benefits such as optimism. Some are conscious about respecting the privacy of others or want to disassociate themselves from the 'disease'. Strategies to strengthen rapport, confidence and sense of 'normality' and to destigmatize the illness may enhance the effectiveness of a YAC.

RESUMO

A single bout of unaccustomed exercise confers protective effect against muscle damage from a subsequent bout of similar activity, that is, repeated bout effect (RBE). It remains unknown whether varying muscle-specific exercise between sessions alters the magnitude of the RBE. This study examined the effects of muscle-specific exercise variation between consecutive sessions on the RBE. Twenty untrained males (21 ± 2 years) were assigned to one of 2 groups (n = 10 per group): (a) 2 sessions of incline curls, Fixed Exercise or (b) 1 session of incline curls followed by 1 session of preacher curls, Varied Exercise, with 7 days between sessions. Subjects performed 5 sets of 6 repetitions at ∼50% of maximal isometric elbow flexor strength during each session. Changes in maximal voluntary isometric and isokinetic torque, range of motion, muscle soreness, and serum creatine kinase were measured before, immediately after, and 24, 48, 72, and 96 hours after each exercise session, and the changes were compared between bouts and between groups. There were significant time effects (p < 0.05) for isometric maximal voluntary contraction, concentric maximal voluntary contraction, range of motion, and muscle soreness during sessions 1 and 2 with no between-group differences. Both groups demonstrated a significantly faster recovery of range of motion and soreness to baseline levels after session 2 compared with session 1. Overall, our findings suggest that incline curls conferred a protective effect during subsequent preacher curls in a similar way to repeating incline curls; therefore, the RBE was not exercise specific.

RESUMO

PURPOSE: To determine the effects of US Army Ranger Training, an 8-week, physically demanding program (energy expenditure of 2,500-4,500 kcal/day) with energy restriction (deficit of 1,000-4,000 kcal/day) and sleep deprivation (<4 h sleep/night) on bone metabolism. METHODS: Blood was collected from 22 men (age 24 ± 4 years) before and after training. Follow-up measurements were made in a subset of 8 subjects between 2 and 6 weeks after training. Serum was analyzed for bone formation biomarkers [bone alkaline phosphatase (BAP) and osteocalcin (OCN)], bone resorption biomarkers [C-telopeptide cross-links of type I collagen (CTX) and tartrate-resistant acid phosphatase (TRAP5b)], calcium, parathyroid hormone (PTH), and vitamin D 25(OH)D increased significantly by 37.3 ± 45.2 % with training [corrected]. A repeated-measures ANOVA with time as the only factor was used to analyze data on the subset of 8 subjects who completed follow-up data collection. RESULTS: BAP and OCN significantly decreased by 22.8 ± 15.5% (pre 41.9 ± 10.1; post 31.7 ± 7.8 ng/ml) and 21.0 ± 23.3% (pre 15.0 ± 3.5; post 11.3 ± 2.1 ng/ml), respectively, with training, suggesting suppressed bone formation. OCN returned to baseline, while BAP remained suppressed 2-6 weeks post-training. TRAP5b significantly increased by 57.5 ± 51.6% (pre 3.0 ± 0.9; post 4.6 ± 1.4 ng/ml) from pre- to post-training, suggesting increased bone resorption, and returned to baseline 2-6 weeks post-training. PTH Increased significantly by 37.3 ± 45.2% with training. No changes in CTX, calcium, or PTH were detected. CONCLUSIONS: These data indicate that multi-stressor military training results in increased bone resorption and suppressed bone formation, with recovery of bone metabolism 2-6 weeks after completion of training.

RESUMO

OBJECTIVE: To elicit utility-based quality of life (QOL) in adolescents and young adults with chronic kidney disease (CKD). STUDY DESIGN: A cross-sectional study was conducted among patients aged 12-25 years with CKD stage 3-5 and 5D from 6 centers in Australia. QOL was measured using a visual analogue scale, and 3 utility-based QOL measures: Health Utilities Index Mark 2 and 3 (HUI2/3), Kidney Disease Quality of Life, incorporating the short form (SF)-12 transformed to SF-6D, and time trade-off (TTO). Multiple linear regression was used to define predictors for TTO QOL weights, SF-6D, and visual analogue scale scores. RESULTS: On a utility scale, with extremes of 0 (death) to 1 (full health), the 27 participants had a mean TTO QOL weight of 0.59 (SD = 0.40), HUI2 of 0.73 (SD = 0.28), HUI3 of 0.74 (SD = 0.26), and SF-6D of 0.70 (SD = 0.14). QOL weights were consistently low across the 4 utility-based instruments with widest variability in TTO responses. Mean QOL weights were higher among predialysis participants. The HUI2 indicated variability in the domain of emotion. From the Kidney Disease Quality of Life measures, decrements were observed in all QOL domains though dialysis patients reported a significantly higher burden attributed to kidney disease. CONCLUSIONS: Adolescent and young adults with CKD report low QOL values. Their utility-based QOL scores imply they are willing to trade considerable life expectancy for perfect health. Holistic care to improve QOL and minimize disease burden are imperative for optimizing health outcomes in young people with CKD, particularly those on dialysis.

RESUMO

BACKGROUND: Young people with advanced chronic kidney disease experience delayed growth and poor psychosocial outcomes. This study aims to elicit the experiences and perspectives of young people waiting for a kidney transplant. METHODS: We conducted semistructured interviews with people aged 12-24 years from 6 Australian renal units. Participants also were asked to complete a journal. Interview transcripts and journal entries were analyzed thematically. RESULTS: 27 individuals participated in the study. 5 major themes were identified: inferiority (impaired body image, failing expectations, sick identity, and being a burden), insecurity (contending with prognostic uncertainty, vulnerability, and doubtful future), injustice (deprived of freedom, victimhood, and lost opportunity), resilience (autonomy and empowerment and maturity), and adjustment mentality (self-blame, reserved optimism, focusing on normality, and self-efficacy). CONCLUSIONS: Young dialysis- and non-dialysis-dependent patients with chronic kidney disease have an impaired sense of self-worth, perceive a precarious future, and feel limited in their physical and psychosocial capacities to have the same potential and opportunity as their healthy peers. Strategies to increase patient autonomy and self-efficacy in treatment management and to manage the emotional burdens of future uncertainties and lifestyle disruptions are needed to protect and promote the health and well-being of young people waiting for a kidney transplant.

RESUMO

Modern international military deployments in austere environments (i.e., Iraq and Afghanistan) place considerable physiological demands on soldiers. Significant physiological challenges exist: maintenance of physical fitness and body composition, rigors of external load carriage, environmental extremes (heat, cold, and altitude), medical illnesses, musculoskeletal injuries, traumatic brain injuries, post-traumatic stress disorder, and environmental exposure hazards (i.e., burn pits, vehicle exhaust, etc.). To date there is very little published research and no comprehensive reviews on the physiological effects of deployments. The purpose of this paper is to overview what is currently known from the literature related mainly to current military conflicts with regard to the challenges and consequences from deployments. Summary findings include: (1) aerobic capacity declines while muscle strength, power and muscular endurance appear to be maintained, (2) load carriage continues to tax the physical capacities of the Soldier, (3) musculoskeletal injuries comprise the highest proportion of all injury categories, (4) environmental insults occur from both terrestrial extremes and pollutant exposure, and (5) post-deployment concerns linger for traumatic brain injury and post-traumatic stress disorder. A full understanding of these responses will assist in identifying the most effective risk mitigation strategies to ensure deployment readiness and to assist in establishment of military employment standards.

RESUMO

A highly porous optical-fiber cladding was developed for evanescent-wave fiber sensors, which contains sensor molecules, maintains guiding conditions in the optical fiber, and is suitable for sensing in aqueous environments. To make the cladding material (a poly(ethylene) glycol diacrylate (PEGDA) polymer) highly porous, a microsphere templating strategy was employed. The resulting pore network increases transport of the target analyte to the sensor molecules located in the cladding, which improves the sensor response time. This was demonstrated using fluorescein-based pH sensor molecules, which were covalently attached to the cladding material. Scanning electron microscopy was used to examine the structure of the templated polymer and the large network of interconnected pores. Fluorescence measurements showed a tenfold improvement in the response time for the templated polymer and a reliable pH response over a pH range of five to nine with an estimated accuracy of 0.08 pH units.

RESUMO

The purpose of this study was to examine the effects of dynamic stretching on running energy cost and endurance performance in trained male runners. Fourteen male runners performed both a 30-minute preload run at 65% VO2max and a 30-minute time trial to assess running energy cost and performance, respectively. The subjects repeated both the trials after either 15 minutes of dynamic stretching (i.e., experimental condition) or quiet sitting (i.e., control condition) while the order was balanced between the subjects to avoid any order effect. The total calories expended were determined for the 30-minute preload run, whereas the distance covered was measured in the time trial. Average resting VO2 increased significantly (p < 0.05) after dynamic stretching (prestretch: 6.2 ± 1.7 vs. poststretch: 8.4 ± 2.1 ml·kg(-1)·min(-1)) but not during the quiet-sitting condition. Caloric expenditure was significantly higher during the 30-minute preload run for the stretching (416.3 ± 44.9 kcal) compared with that during the quiet sitting (399.3 ± 50.4 kcal) (p < 0.05). There was no difference in the distance covered after quiet sitting (6.3 ± 1.1 km) compared with that for the stretching condition (6.1 ± 1.3 km). These findings suggest that dynamic stretching does not affect running endurance performance in trained male runners.

RESUMO

Missions conducted by the U.S. Military during combat involve a multitude of operational stressors that can cause deterioration in physical and military performance of soldiers. Physiological consequences of sustained operational stress include decrements in anabolic hormones, skeletal muscle mass, and loss of bone mineral density. The objective of this review is to examine the current literature and provide commanders with information on the physical and physiological decrements in soldiers conducting sustained operations. The intent is that this will provide commanders with insight on how to plan for missions to incorporate possible countermeasures to enhance or sustain warfighter performance.

RESUMO

INTRODUCTION: Abdominal pain and flank pain cause a significant proportion of emergency department (ED) visits. The diagnosis often remains unclear and is frequently associated with repeat visits to the ED for the same complaint. A rare cause of left upper abdominal and flank pain is compression of the left renal vein between the aorta and the superior mesenteric artery known as nutcracker syndrome. Diagnostic findings on ultrasound include increased left renal vein diameter proximal and peak blood flow velocity increase distal to the superior mesenteric artery. We describe such a patient presenting to an ED repeatedly with severe pain mimicking renal colic before the final diagnosis and intervention occurred. CASE REPORT: A 16-year-old female, long-distance runner presented four times complaining of intractable left upper quadrant abdominal pain radiating to the left flank after exercise. On each visit urinalysis revealed proteinuria and hematuria, and on two visits abdominal computed tomography revealed no kidney stone or dilatation of the collecting system. Ultimately, she was referred to vascular surgery where Doppler ultrasonography was used to diagnose left renal vein compression. Transposition of the left renal vein improved Doppler diameter and flow measurements and eliminated symptoms. CONCLUSION: Emergency physicians must maintain a large list of possible diagnoses during the evaluation of abdominal and flank pain with a repetitive and uncertain etiology. Nutcracker syndrome may mimic other causes of abdominal and flank pain such as renal colic and requires appropriate referral.

RESUMO

Peritonitis is a common complication and major cause of morbidity in children on peritoneal dialysis. In this retrospective longitudinal study, we analysed data retrieved from the Australian and New Zealand Dialysis and Transplant Registry (ANZDATA) on 167 patients aged less than 18 years of age who were treated with peritoneal dialysis during the period from October 2003 to December 2007. During this period there were 100 episodes of peritonitis in 57 patients (0.71 episodes/patient-year), with Gram-positive organisms most commonly isolated (44%). Peritonitis occurred frequently in the first 6 months after starting dialysis, with survival analysis showing peritonitis-free survival rates of 72%, 56% and 36% at 6 months, 1 year and 2 years respectively. Age was a weak predictor of peritonitis on univariate analysis, but previous peritonitis was the only significant predictor in a multivariate Cox proportional hazards model (adjusted hazard ratio 2.02; 95% CI: 1.20 to 3.40, p = 0.008). Peritonitis episodes infrequently resulted in relapse (5%), recurrence (7%) or the need for either temporary or permanent haemodialysis (5% and 7% respectively) and there were no patient deaths directly attributable to peritonitis. Compared with single organism peritonitis, polymicrobial peritonitis was not associated with any statistically significant differences in outcome. Further prospective studies are required to determine the most appropriate prophylactic measures and antibiotic regimens for use in pediatric patients.

RESUMO

To describe the trends in end-stage kidney disease (ESKD) in children in Australia and New Zealand over time and across different ages, we analyzed data from the Australia and New Zealand Dialysis and Transplant Registry (ANZDATA). A total of 1,485 children aged less than 18 years received renal replacement therapy (RRT) during the period from 1963 to 2006, of which children 55.6% were male. The incidence of ESKD increased over the first two decades but has been stable at 8 per million since the mid-1980s. The prevalence of ESKD continues to increase in all age groups, especially among older children, and is currently 50 per million in those aged less than 18 years. The cause of ESKD over the entire cohort was one-third each for glomerulonephritis (32.5%), structural anomalies (hypoplasia/dysplasia, posterior urethral valves or reflux nephropathy, 35.8%), and cystic disease or other conditions (31.7%). Proportionately, glomerulonephritis is becoming less common. Overall, 50% of children were commenced on peritoneal dialysis as the initial RRT modality, 30% were started on hemodialysis, and 20% underwent transplantation pre-emptively. The proportion of children receiving transplants has not increased over time.

RESUMO

OBJECTIVE: Acyclovir therapy in late pregnancy among women with recurrent genital herpes is effective in decreasing genital lesion frequency and subclinical viral shedding rates at delivery, thereby decreasing the need for Caesarean section. Despite good adherence and increased dosing schedules, breakthrough lesions and viral shedding are still observed in some women at or near delivery. Anecdotal evidence suggests that low levels of herpes simplex virus replication at delivery may result in transmission to the neonate. Therefore, defining optimal acyclovir dosing during labour and delivery is warranted. Our objectives were to determine actual maternal and fetal acyclovir levels at delivery, and explore associations between acyclovir levels, duration of labour, and time since last acyclovir dose. METHODS: Twenty-seven patients were prescribed oral acyclovir 400 mg three times daily from 36 weeks' gestation. Cord blood (venous and arterial) and maternal venous blood samples were collected at delivery, and acyclovir levels measured using capillary electrophoresis. Correlations between duration of labour, and time since last acyclovir dose with acyclovir blood levels were calculated. RESULTS: Acyclovir levels were below the published mean steady-state trough value (180 ng/mL) in 52% of venous cord samples, 55% of arterial cord samples, and 36% of maternal samples. There was a significant inverse correlation between the time since last dose and venous cord levels (rs19 = -0.57, P < 0.015), arterial cord levels (rs16 = -0.63, P < 0.01), and maternal acyclovir levels (r10 = -0.69, P < 0.03). CONCLUSION: Oral dosing of acyclovir in women in late pregnancy may result in insufficient levels at delivery to prevent viral shedding. Alternative approaches that incorporate acyclovir dosing through labour, either through oral or intravenous administration, should be evaluated to assess effects on viral shedding.

RESUMO

BACKGROUND: Planning for pregnancy has been associated with reduced unwanted pregnancies and improved pregnancy outcomes. Despite the benefits of planned pregnancy, there are no guideline recommendations on routine counseling regarding pregnancy intention in primary care settings. The objective of the systematic review is to determine the effectiveness of incorporating questions of pregnancy intention into primary care. METHODS: A systematic search of the literature will be conducted for any studies comparing questions of pregnancy intention in primary care settings with no intervention or a control intervention. Types of studies will include randomized controlled trials, non-randomized trials, and observation studies. Participants will include patients of reproductive age presenting to primary health care settings. Interventions will include any assessment of fertility intention and follow-up care compared with a control group or no intervention. Outcomes will include quantitative data with rates for contraceptive uptake, and any pregnancy related outcome. Databases (Ovid MEDLINE; Pubmed; CINAHL; EMBASE; CDR/DARE databases; Web of Science; ISRCTN registry; Clinicaltrials.gov; Cochrane Library) will be searched from the year 2000 to current. Screening of identified articles and data extraction will be conducted in duplicate by two independent reviewers. Methodological quality will be assessed using the Jadad scale. Methodological quality of observational and non-randomized trials will be assessed using the Newcastle-Ottawa scale. Discrepancies will be resolved by consensus or by consulting a third author. Meta-analyses will be performed if appropriate. DISCUSSION: Determining the effect of including questions of pregnancy intention into primary care can provide evidence for the development of clinical practice guidelines and inform primary care providers if this simple and low-cost intervention should be routinely employed. This review will also identify any gaps in the current literature on this topic and provide direction for future research in this area of study. Systematic Review Registration: PROSPERO CRD42015019726.

RESUMO

BACKGROUND: Familial forms of focal segmental glomerulosclerosis (FSGS) are caused by mutations in genes at 1q25-31 (gene for steroid-resistant nephrotic syndrome 2 [NPHS2]), 11q21-22, 19q13 (gene for alpha-actinin 4 and NPHS1), and at additional unidentified chromosomal loci. METHODS: We describe clinical and histopathologic features and results of linkage analysis in nine consecutive index cases with familial FSGS who, together with their families, were referred for genetic studies. RESULTS: Two of the index cases presented in childhood (22%) and seven cases presented in adolescence or adulthood (78%). Six of their families (67%), including the two cases with childhood-onset disease, showed probable autosomal recessive inheritance. FSGS segregated at the 1q25-31 locus in two of these families and at the 11q21-22 locus in four families. None had disease caused by mutations in genes at the 19q13 locus, and no locus was identified in the three remaining families. Clinical features of proteinuria, minimal hematuria, hypertension, preeclampsia, and progressive renal impairment were usually present with autosomal recessive or dominant inheritance and with disease that segregated at the different loci. Eighteen renal biopsies from affected members of eight families showed a strong correlation between tubulointerstitial damage and percentage of obsolescent glomeruli (rho = +0.76; P < 0.01). None of the 13 patients from eight families who underwent transplantation developed recurrent FSGS in their grafts. In general, carriers of autosomal recessive disease had no distinctive clinical features apart from the development of preeclampsia in successive pregnancies. CONCLUSION: Familial forms of FSGS are not uncommon, and presentation frequently is in adolescence or adulthood, even when inheritance is autosomal recessive. Furthermore, carriers of autosomal recessive FSGS often have no distinctive phenotype.

RESUMO

A sensitive plasma assay for acyclovir has been developed and validated. Acyclovir was separated from plasma components using Oasis HLB columns. Separation was obtained with no plasma interference using micellar electrokinetic chromatography (175 mM SDS) and hydroxypropyl-beta-cyclodextrin (100 mM) in 90 mM borate buffer (pH 8.8) containing 0.2% NaCl. High sensitivity was achieved by large volume sample introduction and stacking. The linear range was from 20 to 10000 ng/ml with a limit of quantitation of 20 ng/ml. This method is a viable alternative to HPLC because of its high separation and sensitivity, reproducibility, and adaptability to other nucleoside analogs.

RESUMO

OBJECTIVE: A prospective study to validate the computer-assisted method of measuring palpebral fissure length and philtrum smoothness using digital patient photographs. These are key diagnostic facial features of Fetal Alcohol Syndrome. PARTICIPANTS: Motherisk Program (including Breaking the Cycle), Hospital for Sick Children, Toronto - a clinical, research and teaching program dedicated to antenatal drug, chemical, and disease risk counseling. 40 children referred for FASD assessment, 21 under 4 years old, 19 were 4 years or older. METHODS/ MATERIALS: Facial measurements were obtained directly from the patient by physicians and compared to those obtained by computer software measurement of photographs of the same patient. OUTCOME MEASURES: Palpebral fissure length and philtrum smoothness. RESULTS: The photographic measurements showed shorter palpebral fissure length than the direct measurements when analyzing all children (25.4±2.3 vs .23.2±2.4mm; p<0.0001), and children under four (n=21, 24.7±2.4 vs. 21.6±1.6mm; p<0.0001). The difference for older children (n=19) did not reach statistical significance. The computer found four false positive cases and no false negative cases of clinically short palpebral fissure (sensitivity=100%, specificity=64%). Direct measurement scores for philtrum smoothness were different from the computer's measurements using the frontal view (p=0.0012) but not using the ¾ view. CONCLUSION: The method of computer-assisted measurement tends to underestimate the true length and, hence, over- diagnose short palpebral fissure, especially in children under four years old. This method may serve as a useful fetal alcohol syndrome screening tool.
