Development of a new Adolescent Patient-Provider Interaction Scale (APPIS) for youth at risk for STDs/HIV

PurposeAlthough an adult model of patient-provider mutual exchange of information has been proposed, there is no guiding model for adolescents or measurement methodology. Our purpose was to develop a new scale of patient-provider interaction for adolescents accessing reproductive health care and at risk for sexually transmitted diseases (STDs) and human immunodeficiency virus (HIV), and assess the reliability and validity of the scale.MethodsThe Adolescent Patient-Provider Interaction Scale (APPIS) was developed from the Roter and Hall theory of doctor-patient relationships, previously validated adolescent satisfaction and communication scales, and focus group and individual elicitation interviews. To assess construct validity, the new nine-item APPIS was compared with the satisfaction scale used by the Young Adult Health Care Survey (YAHCS), and Kahn’s Provider Communication Scale. Pearson correlation coefficients were used to examine convergence across scales, and factor analysis of the APPIS was performed.ResultsThe study recruited 192 African American girls aged 17.9 ± 1.7 years (range 15–21 years) from three sites: a county STD clinic (n = 51), urban adolescent clinic (n = 99), and a family planning clinic (n = 42). Most participants (85%) rated their overall health care highly (≥ 7 on a 10-point scale); 49% felt that both the provider and patient were “in charge” of the visit, and 88% “strongly agreed” or “agreed” that there was an equal “exchange of information” during the visit. The APPIS showed good internal consistency (Cronbach alpha = .75), and moderate convergence with the six-item YAHCS scale (r = .57, p < .001) and seven-item Kahn scale (r = .48, p < .001). Three factors emerged from exploratory factor analyses, supporting our conceptualization of patient-provider interaction as being multi-dimensional.ConclusionsA new theory-based scale of adolescent patient-provider interaction compares favorably with previous scales of health care satisfaction and communication. The new APPIS may be useful for evaluating approaches to improve health care outcomes for adolescents at-risk for STDs and HIV.     

Serum electrolytes in children admitted with diarrhoeal dehydration managed with simple salt sugar solution

Diarrheal diseases constitute a major cause of childhood morbidity and mortality in Zimbabwe. Since 1982, it has been the policy in Zimbabwe to use home-based Salt Sugar Solution (SSS) as standard Oral Rehydration Solution (ORS) therapy for both prevention and management of dehydration. The recommended formula is incomplete, lacking both potassium and bicarbonate. It may not, therefore, be as efficacious as complete ORS for the prevention or correction of hypokalemia and acidosis during diarrhea. For this reason, a study was carried out at Harare Central Hospital to assess the type and prevalence of electrolyte abnormalities in dehydrated children who had previously been managed with oral salt sugar solution for acute gastroenteritis. 121 such referred patients had their serum urea and electrolytes estimated on admission prior to further management in the Unit; .38 (27.5%) cases of hypokalemia, 12 (8.9%) of hypernatremia, 52 (5.5%) of hypoatremia and 65 (45.7%) of severe acidosis (bicarbonate level 10 mmol/1) were documented. It is concluded that simple salt sugar solution is ideal for the prevention of dehydration but in cases of established dehydration the WHO complete formula is more appropriate for combating hypokalemia and severe metabolic acidosis.     

Aspergillus fumigatus abscesses of the thyroid with obstruction of the esophagus.

Thyroid invasion by Aspergillus spp. can occur with invasive aspergillosis, although it is rarely diagnosed antemortem. We describe a case of multiple thyroid abscesses from A. fumigatus that caused esophageal obstruction in a patient with myelodysplasia. Despite aggressive antifungal treatment, the outcome was rapidly fatal.     

Early PREdiction of sepsis using leukocyte surface biomarkers: the ExPRES-sepsis cohort study

Purpose

Reliable biomarkers for predicting subsequent sepsis among patients with suspected acute infection are lacking. In patients presenting to emergency departments (EDs) with suspected acute infection, we aimed to evaluate the reliability and discriminant ability of 47 leukocyte biomarkers as predictors of sepsis (Sequential Organ Failure Assessment score?≥?2 at 24 h and/or 72 h following ED presentation).

Methods

In a multi-centre cohort study in four EDs and intensive care units (ICUs), we standardised flow-cytometric leukocyte biomarker measurement and compared patients with suspected acute infection (cohort-1) with two comparator cohorts: ICU patients with established sepsis (cohort-2), and ED patients without infection or systemic inflammation but requiring hospitalization (cohort-3).

Results

Between January 2014 and February 2016, we recruited 272, 59 and 75 patients to cohorts 1, 2, and 3, respectively. Of 47 leukocyte biomarkers, 14 were non-reliable, and 17 did not discriminate between the three cohorts. Discriminant analyses for predicting sepsis within cohort-1 were undertaken for eight neutrophil (cluster of differentiation antigens (CD) CD15; CD24; CD35; CD64; CD312; CD11b; CD274; CD279), seven monocyte (CD35; CD64; CD312; CD11b; HLA-DR; CD274; CD279) and a CD8 T-lymphocyte biomarker (CD279). Individually, only higher neutrophil CD279 [OR 1.78 (95% CI 1.23–2.57); P?=?0.002], higher monocyte CD279 [1.32 (1.03–1.70); P?=?0.03], and lower monocyte HLA-DR [0.73 (0.55–0.97); P?=?0.03] expression were associated with subsequent sepsis. With logistic regression the optimum biomarker combination was increased neutrophil CD24 and neutrophil CD279, and reduced monocyte HLA-DR expression, but no combination had clinically relevant predictive validity.

Conclusions

From a large panel of leukocyte biomarkers, immunosuppression biomarkers were associated with subsequent sepsis in ED patients with suspected acute infection.

Implementing Adolescent Screening,Brief Intervention,and Referral to Treatment (SBIRT) Education in a Pediatric Residency Curriculum

Background: Screening, brief intervention, and referral to treatment (SBIRT) is recommended as part of routine health care for adolescents as well as adults. In an effort to promote universal SBIRT, the Substance Abuse and Mental Health Services Administration awarded funding to residency programs to develop and implement SBIRT education and training. Our project focused on creating scientifically based, developmentally appropriate strategies and teaching materials for the adolescent age range. This paper describes curriculum development and implementation and presents evaluation data. Methods: Pediatric and child psychiatry residents were trained. The training consisted of 4 activities: (1) case-based teaching modules, (2) role-play of motivational interviewing and brief interventions, (3) mock interviews with trained adolescents, and (4) supervised “hands-on” screening and brief interventions. Main outcome measures included trainee satisfaction, and SBIRT knowledge, perceived self-efficacy, and self- and observer report of use of the SBIRT algorithm. Results: Among 150 total participants completing the SBIRT training modules, nearly all (92.3%) were satisfied/very satisfied with the training modules. Knowledge accuracy immediately post training was high, but declined significantly by the end of the first residency year, with little change across subsequent years of residency. Confidence ratings also declined over time. Use of the SBIRT algorithm during the Adolescent Medicine rotation was high according to trainee self- and faculty observer report. Conclusions: We found evidence of training satisfaction, increased confidence in talking to adolescents about substance use, and widespread use of recommended practices immediately following training. Use of a highly structured algorithm to guide practice, and simple, highly structured brief interventions was a successful training approach, as residents self-reported accurate use of the SBIRT algorithm immediately after training. Knowledge and self-confidence declined over time. It is possible that “booster” sessions and ongoing opportunities to review materials could help residents retain knowledge and skills.     

Isolation and characterisation of Mauritius lowland day gecko Phelsuma guimbeaui microsatellite loci

We isolated 315 sequences from a Phelsuma guimbeaui microsatellite-enriched genomic library. Primer sets were designed for 44 loci and used to genotype 29 unrelated individuals belonging to a population in the west of Mauritius. All the loci were polymorphic and the number of alleles ranged from 6 to 34. Mean observed and expected heterozygosity varied from 0.29 to 1.00 and 0.48 to 0.97, respectively. Thirteen loci displayed evidence of deviation from Hardy–Weinberg equilibrium, of which 11 also had an estimated null allele frequency ≥10 %. The microsatellite loci will be used to evaluate the population structure and genetic diversity of P. guimbeaui in Mauritius.
