The Effect of Care Pathways for Hip Fractures: A Systematic Review

We performed a systematic review for primary studies on care pathways (CPs) for hip fracture (HF). The online databases MEDLINE-PubMed, Ovid-EMBASE, CINAHL-EBSCO host, and The Cochrane Library (Cochrane Central Register of Clinical Trials, Health Technology Assessment Database, NHS Economic Evaluation Database) were searched. Two researchers reviewed the literature independently. Primary studies that met predefined inclusion criteria were assessed for their methodological quality. A total of 15 publications were included: 15 primary studies corresponding with 12 main investigations. Primary studies were evaluated for clinical outcomes, process outcomes, and economic outcomes. The studies assessed a wide range of outcome measures. While a number of divergent clinical outcomes were reported, most studies showed positive results of process management and health-services utilization. In terms of mortality, the results provided evidence for a positive impact of CPs on in-hospital mortality. Most studies also showed a significantly reduced risk of complications, including medical complications, wound infections, and pressure sores. Moreover, time-span process measures showed that an improvement in the organization of care was achieved through the use of CPs. Conflicting results were observed with regard to functional recovery and mobility between patients treated with CPs compared to usual care. Although our review suggests that CPs can have positive effects in patients with HF, the available evidence is insufficient for formal recommendations. There is a need for more research on CPs with selected process and outcome indicators, for in-hospital and postdischarge management of HF, with an emphasis on well-designed randomized trials.     

A chronic-constriction injury of the sciatic nerve reduces bilaterally the responsiveness to formalin in rats: a behavioral and hormonal evaluation

Application of four loose ligatures to the sciatic nerve of a rat (chronic constriction injury [CCI]) induces clear hypersensitivity to non-noxious stimulation and chemical irritants. However, in this study, an injection of formalin in the hind paw of a rat with CCI-induced mononeuropathy resulted in an ipsilateral decreased flinching and licking or biting behavior in both phases of the formalin testing. The effect was independent of the formalin concentration used. This altered behavior was accompanied with smaller plasma levels of adrenocorticotrope hormone and corticosterone compared with sham and non-operated animals. Formalin injection in the contralateral nonligated hind paw of CCI rats also reduced the licking or biting behavior as compared with sham-operated and non-operated control animals only in the second phase of the formalin test. Thus, CCI reduces the pain reactivity and hypothalamic-pituitary-adrenal-axis activation to ipsilateral and contralateral formalin injection. Further research should investigate whether the decreased pain reactivity by CCI is situated at the peripheral, spinal, or supraspinal level or is result of changes in the stress reactivity and coping strategies. IMPLICATIONS: We evaluated the changes in the behavioral reactions and the hormonal effects of a noxious chemical stimulus, i.e., formalin injection in animals with previously induced chronic constriction injury to the sciatic nerve. The effect in animals injected at the ipsilateral and contralateral site, sham-operated and controls, were compared.     

The role of the posterior superior temporal sulcus in audiovisual processing

In this study we investigate previous claims that a region in the left posterior superior temporal sulcus (pSTS) is more activated by audiovisual than unimodal processing. First, we compare audiovisual to visual-visual and auditory-auditory conceptual matching using auditory or visual object names that are paired with pictures of objects or their environmental sounds. Second, we compare congruent and incongruent audiovisual trials when presentation is simultaneous or sequential. Third, we compare audiovisual stimuli that are either verbal (auditory and visual words) or nonverbal (pictures of objects and their associated sounds). The results demonstrate that, when task, attention, and stimuli are controlled, pSTS activation for audiovisual conceptual matching is 1) identical to that observed for intramodal conceptual matching, 2) greater for incongruent than congruent trials when auditory and visual stimuli are simultaneously presented, and 3) identical for verbal and nonverbal stimuli. These results are not consistent with previous claims that pSTS activation reflects the active formation of an integrated audiovisual representation. After a discussion of the stimulus and task factors that modulate activation, we conclude that, when stimulus input, task, and attention are controlled, pSTS is part of a distributed set of regions involved in conceptual matching, irrespective of whether the stimuli are audiovisual, auditory-auditory or visual-visual.     

A One-Stop Clinic for Men with Testicular Anxiety

INTRODUCTION

Testicular lumps and orchialgia both cause considerable anxiety, usually related to concerns about possible cancer.

PATIENTS AND METHODS

We established a rapid-access testicular clinic staffed by a urologist and a specialist ultrasonographer in order to delay the time to a definitive diagnosis.

RESULTS

Over a 30-month period, 845 men underwent clinical examination and scrotal ultrasonography. Overall, 4% of men were found to have testicular cancer. The majority of men were found to have normal testes or minor abnormalities and could be re-assured.

CONCLUSIONS

This one-stop clinic reduces the time to a definitive diagnosis which may reduce anxiety suffered by men with testicular complaints and allows rapid identification of those harbouring a testicular malignancy.     

Predictability model of the need for extracorporeal membrane oxygenation in neonates with meconium aspiration syndrome treated with inhaled nitric oxide

Background

As the use of inhaled nitric oxide (iNO) resulted in a decline in the need for extracorporeal membrane oxygenation (ECMO) in neonates with hypoxic respiratory failure, iNO has become an accepted treatment modality even in non-ECMO centers. However, because not all neonates respond to iNO, the timely identification and transfer of nonresponders to an ECMO center are important.

Objectives

The objective of this study was to identify the risk factors predictive of the need of ECMO in neonates with hypoxic respiratory failure after the first 6 hours of iNO treatment in an ECMO center.

Methods and Patient Population

Forty-nine patients with hypoxic respiratory failure transferred for iNO therapy and potential ECMO during a 2-year period were identified in this retrospective study. None of the patients had received iNO before admission. Strict clinical guidelines were used to standardize lung inflation, cardiovascular support, and iNO administration and weaning and to define treatment failure. The relationship between treatment failure (ie, the need for ECMO) and a set of suspected risk factors after 6 hours of iNO administration was examined by logistic regression analysis.

Results

Twenty-two neonates responded to iNO (non-ECMO group) whereas 27 neonates failed and met ECMO criteria (ECMO group). There was no difference between the 2 groups in demographic data, ventilatory support, air leak syndrome at 6 hours of iNO treatment, and survival to discharge. However, the dose and duration of iNO therapy were predictive of the need for ECMO with an adjusted odds ratio of 1.12 (95% CI, 1.01-1.25; P = .04) and 0.45 (95% CI, 0.27-0.65; P = .0002), respectively.

Conclusions

By the end of the first 6 hours of iNO treatment and under the specific conditions established by the use of the clinical guidelines, the dose and the duration of iNO administration were predictive of the probability for the need of ECMO in this patient population. Thus, one can establish a center-specific predictability model for the need of ECMO in neonates with hypoxic respiratory failure treated with iNO if strict clinical guidelines for iNO administration and weaning and respiratory and cardiovascular support are used in the given center.     

Best practices to optimize utilization of the National Living Donor Assistance Center for the financial assistance of living organ donors

Living organ donors face direct costs when donating an organ, including transportation, lodging, meals, and lost wages. For those most in need, the National Living Donor Assistance Center (NLDAC) provides reimbursement to defray travel and subsistence costs associated with living donor evaluation, surgery, and follow‐up. While this program currently supports 9% of all US living donors, there is tremendous variability in its utilization across US transplant centers, which may limit patient access to living donor transplantation. Based on feedback from the transplant community, NLDAC convened a Best Practices Workshop on August 2, 2018, in Arlington, VA, to identify strategies to optimize transplant program utilization of this valuable resource. Attendees included team members from transplant centers that are high NLDAC users; the NLDAC program team; and Advisory Group members. After a robust review of NLDAC data and engagement in group discussions, the workgroup identified concrete best practices for administrative and transplant center leadership involvement; for individuals filing NLDAC applications at transplant centers; and to improve patient education about potential financial barriers to living organ donation. Multiple opportunities were identified for intervention to increase transplant programs’ NLDAC utilization and reduce financial burdens inhibiting expansion of living donor transplantation in the United States.     

A comparison of the psychosocial functioning of children with drug-versus alcohol-dependent fathers

The present study compared the psychosocial functioning of children whose fathers primarily abused illicit drugs other than alcohol (n = 51 ) to children from a demographically matched sample of families whose fathers abused alcohol (n = 51). Children with drug-abusing (DA) fathers exhibited significantly more negative child behaviors on a standardized child-rating scale than did children from homes with alcohol-abusing fathers. In addition, a significantly greater proportion of children with DA fathers met clinical cutoffs indicative of psychosocial impairment (n = 23: 45%) than did children whose fathers abused alcohol (n = 5; 10%). Mediation analyses indicated that severity of drug, legal, medical, employment, and family problems partially mediated the relationship between type of family (i.e., families with fathers who had an alcohol problem versus families with fathers who had a drug problem) and children's psychosocial adjustment.
