Systematic identification and stratification of help-seeking school-aged youth with mental health problems: a novel approach to stage-based stepped-care

We investigated whether a novel visitation model for school-aged youth with mental health problems based on a stage-based stepped-care approach facilitated a systematic identification and stratification process without problems with equity in access. The visitation model was developed within the context of evaluating a new transdiagnostic early treatment for youth with anxiety, depressive symptoms, and/or behavioural problems. The model aimed to identify youth with mental health problems requiring an intervention, and to stratify the youth into three groups with increasing severity of problems. This was accomplished using a two-phase stratification process involving a web-based assessment and a semi-structured psychopathological interview of the youth and parents. To assess problems with inequity in access, individual-level socioeconomic data were obtained from national registers with data on both the youth participating in the visitation and the background population. Altogether, 573 youth and their parents took part in the visitation process. Seventy-five (13%) youth had mental health problems below the intervention threshold, 396 (69%) were deemed eligible for the early treatment, and 52 (9%) had symptoms of severe mental health problems. Fifty (9%) youth were excluded for other reasons. Eighty percent of the 396 youth eligible for early treatment fulfilled criteria of a mental disorder. The severity of mental health problems highlights the urgent need for a systematic approach. Potential problems in reaching youth of less resourceful parents, and older youth were identified. These findings can help ensure that actions are taken to avoid equity problems in future mental health care implementations.

     

Added value of interpreter experience in occult and suspect hip fractures: a retrospective analysis of 254 patients

The influence of experience in categorizing suspect and occult fractures on radiography compared to MRI and clinical outcome has not been studied. The aim of this study is to evaluate the importance of experience in diagnosing normal or suspect hip radiographs compared to MRI. Primarily reported normal or suspect radiography in 254 patients with low-energy hip trauma and subsequent MRI was re-evaluated by two experienced reviewers. Primary readings and review were compared. The prevalence of fractures among normal and suspect radiographic studies was assessed. Clinical outcome was used as reference. At review of radiography, 44 fractures (17 %) were found. Significantly more fractures were found among suspect cases than among normal cases. At MRI, all 44 fractures were confirmed, and further 64 fractures were detected (25 %). MRI detected all fractures with no missed fractures revealed at follow-up. There were a significantly higher proportion of fractures at MRI among the suspect radiographic diagnoses for both the primary report and at review than among occult cases. The more experienced reviewers classified radiography examinations with higher accuracy than primary reporting general radiologists. There was almost complete agreement on MRI diagnoses.     

Behavioral impairments of the aging rat

Several disturbances occurring during aging of humans and rodents alike stem from changes in sensory and motor functions. Using a battery of behavioral tests we have studied alterations in performance with advancing age in female and male rats of some frequently used strains. In parallel, we collected survival and body weight data. The median survival age was similar for female and male Sprague-Dawley rats, inbred female Lewis and outbred male Wistar rats (29-30 months). In contrast, male Fisher 344 had a significantly shorter median life span. During aging there is a gradual decline in locomotor activity and explorative behavior while disturbances of coordination and balance first became evident at more advanced age. In old age, also weight carrying capacity, limb movement and temperature threshold were impaired. While whole body weight continues to increase over the better part of a rats' life span, the behavioral changes in old age associated with a decrease in both total body weight and muscle mass. Dietary restriction increases median life span expectancy; retards the pace of behavioral aging and impedes sarcopenia. Housing in enriched environment did not improve the scoring in the behavioral tests but tended to increase median life span. Finally, there was an agreement between behavioral data collected from longitudinal age-cohorts and those obtained from multiple age-cohorts.     

Activation of the cortical pain network by soft tactile stimulation after injection of sumatriptan

The anti-migraine drug sumatriptan often induces unpleasant somatosensory side effects, including a dislike of being touched. With a double-blind cross-over design, we studied the effects of sumatriptan and saline on perception (visual analogue scale) and cortical processing (functional magnetic resonance imaging) of tactile stimulation in healthy subjects. Soft brush stroking on the calf (n=6) was less pleasant (p<0.04) and evoked less activation of posterior insular cortex in the sumatriptan compared to the saline condition. Soft brushing activated pain processing regions (anterior insular, lateral orbitofrontal, and anterior cingulate cortices, and medial thalamus) only in the sumatriptan condition, whereas activation of somatosensory cortices was similar in both conditions. Soft brush stroking on the palm (n=6) was equally pleasant in both conditions. One possible mechanism for the activation of pain processing regions by brush stroking is sensitization of nociceptors by sumatriptan. Another possibility is inhibition of a recently discovered system of low-threshold unmyelinated tactile (CT) afferents that are present in hairy skin only, project to posterior insular cortex, and serve affective aspects of tactile sensation. An inhibition of impulse transmission in the CT system by sumatriptan could disinhibit nociceptive signalling and make light touch less pleasant. This latter alternative is consistent with the observed reduction in posterior insular cortex activation and the selective effects of stimulation on hairy compared to glabrous skin, which are not explained by the nociceptor sensitization account.     

Laparoscopic Roux-En-Y Gastric Bypass is Effective and Safe in Over 55-year-old Patients: A Comparative Analysis

Background

Controversy exists regarding the effectiveness and safety of laparoscopic Roux-en-Y gastric bypass (LRYGB) in elderly patients. We evaluated our outcomes of LRYGB in patients aged ≥55 years.

Methods

A total of 549 consecutive patients underwent LRYGB as primary operation and 132 were ≥55 years old. Patients were divided in two groups: group <55 years comprised 417 patients, with mean age (±SD) of 41.15 ± 8.47 years; group ≥55 years comprised 132 patients, with mean age of 59.43 ± 3.81 years. Mean preoperative body mass index was 47.01 ± 7.47 and 46.21 ± 7.47 respectively, whereas mean excess weightloss percent (EW%) was 88.06 ± 30.28 and 84.86 ± 29.87 %. Early morbidity (30 days) and outcomes at 6, 12, and 24 months follow-up were evaluated.

Results

Significant difference was found in operative time (84.19 ± 29.05 vs. 90.89 ± 30.95 min, p = 0.03). One conversion to open procedure occurred in group <55 years, whereas three occurred in group ≥55 years (p = 0.04). Intraoperative complications occurred in 22 patients (5.27 %) in group <55 years versus 19 in group ≥55 years (14.39 %), which was statistically significant (p = 0.001). One case of death occurred in the younger group. Overall postoperative morbidity rate was 18.7 % in group <55 years and 25.76 % in group ≥55 years, with no significant difference (p = 0.08). Mean EWL% at 12 months in group <55 years was 65.95.05 ± 26.96 versus 62.61 ± 41.78 in group ≥55 years, whereas at 24 months it was 65.08 ± 29.68 versus 64.48 ± 18.44 with no significant difference between the groups (p = 0.51; p = 0.92).

Conclusions

LRYGB for patients ≥55 years achieves outcomes and complications rates comparable to the younger population. Patients should not be denied bariatric surgery for the age alone.
