Nutritional Status in Patients with Esophageal Cancer Receiving Chemoradiation and Assessing the Efficacy of Usual Care for Nutritional Managements

Background: Malnutrition is prevalent in esophageal cancer patients which affects cancer prognosis. The purpose of this study was a comprehensive assessment of nutritional status during Chemoradiation (CRT). Methods: Newly diagnosed adults with esophageal cancer were recruited for this study. Patient-Generated- Subjective Global Assessment (PG-SGA), anthropometric indices, body composition, dietary intake, laboratory tests, and nutritional-related complications were assessed before, after, and 4 to 6 weeks after CRT. Results: Seventy-one cases were enrolled. The mean age was 66.8±12 years. Patients’ mean weight loss was 2.42±2.4 kilograms during treatment. A significant reduction observed in mean MUAC (26.68±4.9 vs. 25.42±5.1 cm), fat mass percentage (24.11±11.8 vs. 22.8±12.5), fat free mass index (16.87±2.4 vs. 16.47±2.6 kg/m2) and hand grip strength (43.2±19 vs. 36.1±20 kg) during CRT (all p-values <0.0001). We had also a non-significant change in mean energy intake (19.5±11 vs. 18.3±11 kcal/kgw. day) and protein intake (0.56±0.4 vs. 0.66±0.5 g/kgw.day) during CRT.  In our assessment before, immediately after and 4-6 weeks following CRT, we recorded energy intake insufficiency in 55.7%, 58.7% and 27.3% and protein intake inadequacy in 89.8%, 89.1% and 72.7% of cases, respectively. The most common complications were dysphagia (56.7%), anorexia (25%), and constipation (47.9%) at admission. Dysphagia improved in some cases (42%), but anorexia (35%), early satiety (25%), Esophagitis (25%), dysosmia (21%) and dysgeusia (17%) were increased as CRT complication. yet, 25% of patients had dysphagia and 34.4% had constipation 4-6 weeks after CRT. The twelve-months mortality was significantly associated with lower BMI after CRT, primary PG-SGA score, weight loss, BMI<18.5, MUAC, physical performance, living in rural or urban areas, addiction. Conclusion: Our study demonstrated a high prevalence of malnutrition among esophageal cancer patients which worsened during Chemoradiotherapy. Our findings warrant early screening and monitoring of nutritional status and effective nutritional interventions with symptoms management during treatment in these patients.     

Transcultural adaptation and validation of a French version of the Prosthetic Limb Users Survey of Mobility 12-item Short-Form (PLUS-M/FC-12) in active amputees

BackgroundThe PLUS-M 12-item Short-Form is a self-questionnaire that assesses the perceived capacity of lower limb amputees (LLAs) to perform a number of daily-life activities. Its psychometric properties are excellent (intraclass correlation coefficient [ICC] > 0.9, fast administration and scoring, normative data available), and it can be used in clinical practice or for research purposes.ObjectiveWe aimed to develop a French version of this questionnaire and to assess its psychometric properties.MethodsWe followed international recommendations for translation and cross-cultural validation of questionnaires. In total, 52 LLAs (age 53 ± 16, 40 males, 28/12/12 transtibial/Gritti-Stokes/transfemoral, 20/28/4 ischemic/traumatic/other) participated. Criterion and construct validities were assessed with the Pearson correlation coefficient (PCC) between the PLUS-M 12-item Short-Form and other constructs (Prosthetic-Profile-of-the-Amputee-Locomotor Capabilities Index, Activities-specific Balance Confidence scale, 2-min walking test and Timed Up and Go test), internal consistency with the Cronbach α and reliability with the ICC in 46 individuals who completed the questionnaire twice in a 7-day interval.ResultsThe mean (SD) PLUS-M 12-item Short-Form T-score was 56.1 (7.8; range 40.3 to 71.4). Construct and criterion validity, internal consistency and reliability ranged from low to excellent (r = 0.43 to 0.84, P < 10⁻² to 0.002; Cronbach α = 0.90, ICC = 0.89 [0.81–0.94]). We found no floor or ceiling effect.ConclusionsThe French version of the PLUS-M 12-item Short-Form has good to excellent psychometric properties, comparable to those of the original version. Its use could definitely be proposed for both clinical and research purposes, once its validation is completed by assessing other psychometric qualities, especially sensitivity to change.

Preoperative tendon retraction,not smoking,is a risk factor for failure with continuity after rotator cuff repair

BackgroundSmoking is a poor prognostic factor for healing after rotator cuff repair and is associated with inferior results. We hypothesized that smokers would have higher recurrent tear rates and more postoperative myotendinous junction (MTJ) retraction in healed repairs than nonsmokers three months postoperatively.MethodsRotator cuff repairs (RCRs) were retrospectively reviewed over a 2-year period. Patients underwent magnetic resonance imaging (MRI) within 6 months prior to surgery and again at 3 months postoperatively. Seventy-nine patients were included and stratified by smokers versus nonsmokers. Baseline patient demographics, tear characteristics, and surgical factors were collected. Preoperative and postoperative MRIs were assessed to quantify the MTJ position and to establish the recurrent tear rate.ResultsFor the total cohort (nonsmokers, n = 56; smokers, n = 23), significant differences in age, race, and traumatic onset of injury existed between groups. There were no significant differences in recurrent tear between smokers (26%) and nonsmokers (27%), but nonsmokers were more satisfied. For patients with healed RCRs (nonsmokers, n = 41; smokers, n = 17), there were significant differences in race. On univariate analysis, nonsmokers had a significantly more lateral MTJ postoperatively (P = 0.05). On multivariable regression analysis, medialized postoperative MTJ position in healed cuffs was driven only by greater preoperative rotator cuff retraction preoperatively. There were no significant differences in MTJ position based on smoking status for patients with healed RCRs.ConclusionSmoking does not appear to be an independent risk factor for postoperative MTJ retraction in healed RCRs, also known as failure in continuity. Preoperative tear size and retraction play the biggest roles in predicting postoperative MTJ position, regardless of smoking status. There are no significant differences in patient-reported outcomes for patients with healed RCRs, but nonsmokers had more satisfaction following RCR in the total cohort.Level of EvidenceLevel III; Retrospective cohort study; Diagnostic study     

The efficacy of integrated cognitive behavioral therapy (CBT) and acupressure versus CBT for insomnia: a three-arm pilot randomized controlled trial

ObjectivesThis pilot study aimed to examine the efficacy of integrated cognitive behavioral therapy (CBT) and acupressure in treating insomnia and its daytime impairments in a Chinese adult population.Methods40 eligible participants with insomnia were randomly assigned to either the integrated CBT and acupressure (CBTAcup) group (n = 14), the CBT group (n = 13), or the waitlist control (WL) group (n = 13). Participants in the CBTAcup group attended a 2-hour integrated CBT and self-administered acupressure group treatment once per week for six consecutive weeks, while participants in the CBT group attended six weekly 2-hour CBT for insomnia. Sleep, mood, daytime impairments, quality of life, and treatment credibility and adherence were assessed at baseline, immediate post-treatment (Week 7), and 4-week post-treatment (Week 11).ResultsLinear mixed-effects models showed that both the CBTAcup and CBT groups had significantly lower insomnia severity (d = −1.74 and d = −2.61), dysfunctional beliefs related to sleep (d = −2.17 and −2.76), and mental fatigue (d = −1.43 and −1.60) compared with the WL group at Week 7. The CBTAcup group provided additional benefits in reducing total fatigue (d = −1.43) and physical fatigue (d = −1.45). Treatment credibility was found to be improved in the CBTAcup group from baseline to Week 7.ConclusionsIntegrated CBT and acupressure demonstrated comparable efficacy to pure CBT in treating insomnia symptoms, with additional advantages to improve fatigue symptoms and acceptability in the Chinese population. Further methodologically rigorous studies on a larger scale and longer follow-up are warranted to confirm these findings.     

Risks and benefits of timely screw removal after thoracolumbar spine fractures treated with non-fusion technique

BackgroundPercutaneous-short segment screw fixation (SSSF) without bone fusion has proven to be a safe and effective modality for thoracolumbar spine fractures (TLSFs). When fracture consolidation is confirmed, pedicle screws are no longer essential, but clear indications for screw removal following fracture consolidation have not been established.MethodsIn total, we enrolled 31 patients with TLSFs who underwent screw removal following treatment using percutaneous-SSSF without fusion. Plain radiographs, taken at different intervals, measured local kyphosis using Cobb’ angle (CA), vertebra body height (VBH), and the segmental motion angle (SMA). A visual analogue scale (VAS) and the Oswestry disability index (ODI) were applied pre-screw removal and at the last follow-up.ResultsThe overall mean CA deteriorated by 1.58° (p < 0.05) and the overall mean VBH decreased by 0.52 mm (p = 0.001). SMA preservation was achieved in 18 patients (58.1%) and kyphotic recurrence occurred in 4 patients (12.9%). SMA preservation was statistically significant in patients who underwent screw removal within 12 months following the primary operation (p = 0.002). Kyphotic recurrence occurred in patients with a CA ≥ 20° at injury (p < 0.001) with a median interval of 16.5 months after screw removal. No patients reported worsening pain or an increased ODI score after screw removal.ConclusionScrew removal within 12 months can be recommended for restoration of SMA with improvement in clinical outcomes. Although, TLSFs with CA ≥ 20° at the time of injury can help to predict kyphotic recurrence after screw removal, the clinical outcomes are less relevant.     

Subthalamic dynamic neural states correlate with motor symptoms in Parkinson’s Disease

ObjectiveThis study aims to discriminate the dynamic synchronization states from the subthalamic local field potentials and investigate their correlations with the motor symptoms in Parkinson’s Disease (PD).MethodsThe resting-state local field potentials of 10 patients with PD were recorded from the subthalamic nucleus. The dynamic neural states of multiple oscillations were discriminated and analyzed. The Spearman correlation was used to investigate the correlations between occurrence rate or duration of dynamic neural states and the severity of motor symptoms.ResultsThe proportion of long low-beta and theta synchronized state was significantly correlated with the general motor symptom and tremor, respectively. The duration of combined low/high-beta state was significantly correlated with rigidity, and the duration of combined alpha/high-beta state was significantly correlated with bradykinesia.ConclusionsThis study provides evidence that motor symptoms are associated with the neural states coded with multiple oscillations in PD.SignificanceThis study may advance the understanding of the neurophysiological mechanisms of the motor symptoms and provide potential biomarkers for closed-loop deep brain stimulation in PD.
