Disentangling the influence of neighborhood and individual characteristics on early residential mobility among newly diagnosed patients with schizophrenia: a multilevel analysis

Purpose

Early residential mobility of schizophrenic patients may relate to discontinuity of treatment and adverse outcome. However, factors influencing early residential mobility of these patients are still poorly examined. The aim of this study was to disentangle the influence of individual and neighborhood characteristics on early residential mobility of schizophrenic patients.

Methods

The study used administrative data of 13, 400 individuals newly diagnosed with schizophrenia in Quebec between 2001 and 2002. These individuals were nested in 163 different health territories. Multilevel analyses were used to assess the contribution of individual and neighborhood characteristics on early residential mobility.

Results

The final model indicates that at the individual level, being men, wonder patients and physical comorbidity increased the likelihood of early residential mobility whereas older patients were less likely to migrate earlier. The health territory level explains about 7 % of the variation of early residential mobility and variables influencing residential mobility at this level are the fourth and the third quartiles of the population density.

Conclusions

Factors influencing early residential mobility of schizophrenic patients are located at both individual and neighborhood levels. This suggests that policies targeting only one-level factors are unlikely to significantly delays early residential mobility.     

Comparison of Two Preoperative Inspiratory Muscle Training Programs to Prevent Pulmonary Complications in Patients Undergoing Esophagectomy: A Randomized Controlled Pilot Study

Background

Postoperative pulmonary complications (PPCs) are the most commonly reported complications after esophagectomy. The aim of this study was to examine the effect and feasibility of preoperative inspiratory muscle training-high intensity (IMT-HI), and IMT-endurance (IMT-E) on the incidence of PPCs in patients following esophagectomy for esophageal cancer (EC).

Method

A single-blind, randomized, clinical pilot study was conducted between 2009 and 2012. Forty-five participants were assigned to either IMT-HI or IMT-E. Effectiveness was assessed by analyzing PPCs, length of hospital stay (LOS), duration of mechanical ventilation, stay on the intensive care unit, and number of reintubations. Maximal inspiratory pressure and lung function changes were recorded pre- and post-training. Feasibility was assessed by IMT-related adverse events, training compliance, and patients’ satisfaction.

Results

Thirty-nine patients could be analyzed, 20 patients in the IMT-HI arm and 19 patients in the IMT-E arm. The incidence of PPCs differed significantly between groups and was almost three times lower for the IMT-HI group (4 vs. 11 patients; p = 0.015). Other differences in favor of the IMT-HI group were LOS (13.5 vs. 18 days; p = 0.010) and number of reintubations (0 vs. 4 patients; p = 0.030). Both interventions proved to be equally feasible.

Conclusion

Preoperative IMT-HI showed to be a promising, effective, and feasible intervention to reduce PPCs in EC patients undergoing esophagectomy. Further research with a larger sample size is recommended.     

Development of microsatellite markers for the critically endangered frog Telmatobufo bullocki and cross-species amplification in two related species

Fifteen microsatellite markers were developed for Telmatobufo bullocki, a critically endangered frog species from Chile. Genetic diversity that was assessed in 29 individuals from one location showed 3–19 alleles per locus. These markers were then tested for cross-species amplification in two related and similarly threatened species. The markers will be used in genetic studies aiding the management and conservation of T. bullocki.     

Effect of preoperative consumption of high carbohydrate drink (Pre-Op®) on postoperative metabolic stress reaction in patients undergoing radical prostatectomy

Aim

To investigate the effects of oral carbohydrate solution consumed until 2 h before the surgery in the patients that would undergo open radical retropubic prostatectomy on postoperative metabolic stress, patient anxiety, and comfort.

Method

A total of 50 adult patients, who were in ASA I–II group and would undergo open radical retropubic prostatectomy, were included in the study. While Group 1 = CH (n = 25) received oral glucose solution, Group 2 = FAM (n = 25) was famished starting from 24:00 h. Blood glucose, insulin, and procalcitonin levels of the patients were recorded, and the patients completed state-trait anxiety inventory (STAI) test, which reflects the anxiety level of the patients, both before surgery and on the postoperative 24th hour. In order to evaluate patient comfort, senses of hunger, thirst, nausea, and cold were assessed in the morning prior to the surgery.

Results

No difference was observed between the two groups in terms of demographic data and insulin resistance levels (p > 0.05). Comparing with the preoperative levels, insulin resistance showed statistically significant elevation in both groups (p < 0.05). Procalcitonin levels were similarly increased in both groups in the postoperative period (p < 0.05). Preoperative and postoperative STAI state scores were similar in both groups (p > 0.05). With regard to preoperative patient comfort, sense of hunger was present in lesser number of subjects and at lower level in Group 1 (p < 0.05).

Conclusion

Preoperative consumption of high carbohydrate drink (Pre-op^®) decreases insulin resistance and enhances patient comfort leading to lesser sense of hunger and thirst in the preoperative period in open radical retropubic prostatectomies.
