Effects of photobiomodulation as an adjunctive treatment in chronic obstructive pulmonary disease: a narrative review.

Chronic obstructive pulmonary disease (COPD) is a disease characterized by chronic airway inflammation and remodeling and lung parenchymal inflammation and destruction, which result in many pulmonary and extrapulmonary manifestations. The anti-inflammatory effect of photobiomodulation (PBM) has been reported in previous studies. This review was conducted to evaluate the direct effect of PBM on lung inflammation in COPD. The other effects of PBM on modulation of peripheral and respiratory muscle metabolism and angiogenesis in lung tissues were also discussed. The databases of PubMed, Cochrane Library, and Google Scholar were searched to find the relevant studies. Keywords included PBM and related terms, COPD-related signs, and lung inflammation. A total of 12 articles were selected and reviewed in this study. Based on the present review, PBM is helpful in reducing lung inflammation through decreasing the inflammatory cytokines and chemokines at multiple levels and increasing anti-inflammatory cytokines. In addition, PBM also improves both peripheral and respiratory muscle metabolism and promote angiogenesis. This review demonstrated that PBM is a promising adjunctive treatment modality for COPD management which merits further validation.

Comparing the Efficacy of Intra-Articular Single Platelet-Rich Plasma(PRP) versus Novel Crosslinked Hyaluronic Acid for Early-Stage Knee Osteoarthritis: A Prospective, Double-Blind, Randomized Controlled Trial.

Background and Objectives: For the treatment of knee osteoarthritis (OA), intra-articular platelet-rich plasma (PRP) and novel crosslinked single-dose hyaluronic acid (HA) have both been reported to improve outcomes, but no study has compared them for the treatment of knee OA. We hypothesized patients with early-stage knee OA who received PRP injections would have more WOMAC score changes than those who received HA injections. This is the first prospective, double-blind, parallel, randomized controlled trial comparing the efficacy of intra-articular single-dose PRP versus novel crosslinked HA (HyajointPlus) for treating early-stage knee OA. Materials and Methods: This study analyzed 110 patients randomized into the PRP (n = 54) or HA (n = 56) groups. The primary outcome is the change of WOMAC score at 1-, 3-, and 6-month follow-ups compared to baseline. Results: The data revealed significant improvements in all WOMAC scores in the PRP group at 1-, 3-, and 6-month follow-up visits compared with the baseline level except for the WOMAC stiffness score at the 1-month follow up. In the HA group, significant improvements were observed only in the WOMAC pain score for all the follow-up visits and in WOMAC stiffness, function, and total scores at 6-month follow-up. When comparing the change of WOMAC score at 1-, 3-, and 6-month follow-ups, no significant differences were found between PRP and HA group. Conclusions: This study revealed that both PRP and HA can yield significant improvements in WOMAC scores at 6-month follow-up without any between-group differences at 1-, 3-, and 6-month follow-ups. Thus, both the single-injection regimens of PRP and HA can improve the functional outcomes for treating early-stage knee OA.

Pectin of cacao pod husk, an efficient immunostimulant for white shrimp, Litopenaeus vannamei.

The disposal of cacao pod husk, a byproduct of cacao bean processing, can cause serious adverse environmental impacts, motivating scientist to explore and develop potential beneficial applications of this resource. Dried cacao pod husk was extracted with ethanol to obtain a 10.6% pectin of cacao pod husks (pCPH), and its effects on the immunocompetence of Litopenaeus vannamei were estimated. Measured variables included total haemocyte count, differential haemocyte count, phenoloxidase activity, respiratory bursts, as well as phagocytic activity and clearance efficiency against Vibrio alginolyticus after receiving pCPH at 0, 1.5, 3, and 6 µg shrimp-1 for 0, 1, 3 and 7 days via injection, and their resistance to thermal stress and V. alginolyticus infection were further evaluated. No significant differences were observed in total haemocyte count, differential haemocyte count, and respiratory bursts in shrimp receiving pCPH at 1.5 µg shrimp-1 for 1 day; however, these variables were significantly elevated after 3 days of injection, compared to the control group. The significantly increased phenoloxidase activity was assessed in shrimp receiving pCPH at 1.5, 3 and 6 µg shrimp-1 within 3 days, and activity returned to the baseline after 7 days. Furthermore, the reduced phenoloxidase activity per granulocytes or respiratory bursts per haemocytes maintained homeostasis following the variation of haemogram. For gene expression assessments in haemocytes, the immune-related genes of the lipopolysaccharide and ß-1,3-glucan binding protein, prophenoloxidase II and anti-lipopolysaccharide factor as well as innate immune signaling pathway-related genes of toll-like receptors 1 and 3 significantly increased after shrimp received pCPH for 1 day. The increases in phagocytic activity and clearance efficiency were only detected in shrimp receiving pCPH at 6 µg shrimp-1 within 7 days, compared to the control. There was no significant difference in the mortality ratio of shrimp against hyperthermal stress when they received pCPH for 1 day, and the significant higher resistance to hypothermal stress and V. alginolyticus infection were found in shrimp received pCPH at 6 µg shrimp-1 for 1 days than those in the other treatments. It is therefore found that pCPH triggers immune responses serving as an immunostimulant capable of enhancing resistance against V. alginolyticus and hypothermal stress.

Injection of an extract of fresh cacao pod husks into Litopenaeus vannamei upregulates immune responses via innate immune signaling pathways.

Immunostimulation is a novel method and a promising development in aquaculture. Products derived from plants exhibit various biological activities. In this study, the hot-water extract isolated from fresh cacao (Theobroma cacao) pod husks (CPHs) was administered by injection to evaluate cellular signaling pathways of innate immunity, the immunostimulating potential, disease resistance, and hypothermal tolerance of white shrimp, Litopenaeus vannamei. Results showed significant increases in the total hemocyte count, semigranular cells, granular cells, phenoloxidase activity, and respiratory bursts (RBs) of hemocytes per unit of hemolymph at 1 day, and in phagocytic activity toward and the clearance efficiency of Vibrio alginolyticus at 1-3 days after shrimp were injected with fresh CPH extract at 40 µg shrimp-1. However, only RBs per hemocyte had significantly decreased at 1 day after the injection. All immune parameters had returned to control levels by 3 days after receiving fresh CPH extract except for RBs, phagocytic activity, and the clearance efficiency, which had returned to control values by 7 days. Furthermore, at 1 day after the injection, the peroxinectin, prophenoloxidase (proPO) II, toll-like receptors (TLR) 3, signal transducer and activator of transcription (STAT), and crustin in shrimp receiving fresh CPH extract at 20 µg shrimp-1, and the lipopolysaccharide and ß-1,3-glucan-binding protein, proPO II, TLR1, and STAT in shrimp receiving fresh CPH extract at 40 µg shrimp-1 were significantly higher than those of shrimp receiving saline. After injecting fresh CPH extract at 10-40 µg shrimp-1 and 40 µg shrimp-1, the mortality of shrimp challenged with V. alginolyticus and exposed to 14 °C for 96 h significantly decreased, respectively. These results suggest that fresh CPH extract can be used as an immunostimulant and a physiological regulator for shrimp through injection administration to enhance immunological and physiological responses, which can elevate the resistance against V. alginolyticus and tolerance against hypothermal stress in L. vannamei.

Comprehensive Exercise Capacity and Quality of Life Assessments Predict Mortality in Patients with Pulmonary Arterial Hypertension.

BACKGROUND: The 6-minute walk test (6MWT) and cardiopulmonary exercise test (CPET) are exercise tests associated with physical function, quality of life and hemodynamic data in patients with pulmonary arterial hypertension (PAH). This study was conducted to assess correlations between exercise capacity, quality of life and disease functional classification, and to analyze the value of comprehensive assessments in predicting mortality in patients with PAH. METHODS: Fifty-four patients with PAH were enrolled. Comprehensive assessments including exercise capacity evaluated using the 6MWT and CPET, and health-related quality of life evaluated using the Short Form 36 (SF-36) questionnaire were performed in all participants. The patients were followed for 2 years with the end point of mortality. RESULTS: The survivors had a longer 6-minute walking distance, higher peak oxygen uptake and higher physical component score of the SF-36 than the non-survivors. In addition, exercise capacity combined with SF-36 predicted 2-year mortality in the patients with PAH. The patients with lower peak oxygen uptake (peak VO2 < 11.03 mL/kg/ min) and lower physical component score (score < 44.54) had a higher mortality rate than those with a higher peak VO2 and higher physical component score (adjusted hazard ratio = 19.95, p = 0.011). CONCLUSIONS: Comprehensive assessments of exercise capacity and quality of life can be used to predict 2-year mortality in patients with PAH.

Association between the severity of femoral condylar cartilage erosion related to knee osteoarthritis by ultrasonographic evaluation and the clinical symptoms and functions.

OBJECTIVE: To determine the association between the severity of femoral condylar cartilage erosion resulting from knee osteoarthritis (OA) by an ultrasonographic grading system and the clinical symptoms and functions. DESIGN: Cross-sectional study. SETTING: A tertiary center. PARTICIPANTS: Participants (N=101) with and without subjective complaints of knee discomfort were consecutively enrolled. Patients who had ever received knee arthroplasty, who had inflammatory arthritis, and whose knee flexion range of motion was <90° were excluded. A total of 194 knees were evaluated. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: A semiquantitative ultrasonographic grading system was used to evaluate the severity of femoral condylar cartilage erosion. The clinical symptoms and functions were evaluated with the visual analog scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Lequesne index. The association of the VAS/WOMAC/Lequesne index with the ultrasonographic grading was assessed. RESULTS: Positive linear associations were found between the ultrasonographic grading and the following: the VAS and the total scores and pain subscales of both the Lequesne index and WOMAC. Multivariate logistic regression analysis revealed grade-dependent association between VAS and ultrasonographic grading after adjusting for age, sex, and body mass index. The WOMAC and Lequesne index scores were associated with the ultrasonographic grading in more severe degrees, particularly in the pain subscales. CONCLUSIONS: This semiquantitative ultrasonographic grading system may well reflect the clinical symptoms and functions related to knee OA as evaluated by the VAS, WOMAC, and Lequesne index. This method provides a more comprehensive description and measurement of knee OA.

[Relationship of the effectiveness of care management services and burdens of primary family caregivers].

BACKGROUND: In Taiwan, long-term care management centers hold primary responsibility for administering long-term care services, assisting with long-term care placements, and sharing the care burden with family caregivers in need. Research into the effectiveness of current care management services and the effectiveness of these services in reducing care burdens remains limited. PURPOSE: This study investigates the relationship among care management center service effectiveness, care management personnel, and burdens in relation to the provision of care services from the prospective of caregivers. METHODS: A purposive sampling method and structured questionnaire survey were used to conduct telephone interviews with 154 home caregivers who had been transferred from care management centers to homecare service centers. RESULTS: Participants expressed overall satisfaction with care management centers and with the services provided by these centers. Satisfaction toward the care managers' professional competence was associated with lower physical burden for caregivers. Participants' psychological and social burdens were associated with overall satisfaction with the care management centers and their satisfaction with the services provided by care managers. CONCLUSIONS: The implementation of care management services has improved satisfaction. However, center services remain inadequate to reduce the psychological and social burdens of caregivers. Greater focus on these two aspects will be critical to the successful implementation of the proposed intensive care management model and multiple services intervention in order to meet the complex care needs of home service recipients and their primary caregivers.

Successful kidney transplantation from a live donor with immune thrombocytopenia: a case report.

Organ transplantation from donors with immune thrombocytopenia (ITP), a condition involving the autoantibody-mediated destruction of platelets, is a topic of debate due to the potential for transplantation-mediated autoimmune thrombocytopenia (TMAT), a rare but potentially fatal complication. Previous reports have described transplants from deceased liver donors with ITP who had very low platelet counts and disease largely refractory to treatment. Here, we present the first case of living kidney transplantation from a donor with ITP who underwent preoperative treatment, with concurrent splenectomy performed to reduce the long-term risk of spontaneous hemorrhage. To ensure the safety of the procedure, we monitored perioperative rotational thromboelastometry parameters and platelet counts, leading to the normalization of the donor's platelet levels. The recipient experienced an uneventful recovery of renal function without perioperative bleeding or the development of TMAT. Our report suggests that kidney transplantation from a donor with well-managed ITP is safe, and such a condition should not be considered a contraindication for donation.

Effects of noxious versus innocuous thermal stimulation on lower extremity motor recovery 3 months after stroke.

OBJECTIVE: To examine the effects of thermal stimulation (TS) on the lower extremity (LE) movement and function in patients with stroke. DESIGN: A double-blinded randomized controlled trial. SETTING: A university hospital. PARTICIPANTS: Patients (N=34) at least 3 months after stroke were randomly assigned into the experimental and the control groups. INTERVENTIONS: In addition to regular rehabilitation, the experimental group received a 30-minute noxious TS protocol (heat pain 46-47°C/cold pain 2-3°C) 3days/wk for 8 weeks, and the control group received a 30-minute innocuous TS protocol (heat 40-41°C/cold 23-24°C) 3d/wk for 8 weeks. MAIN OUTCOME MEASURES: The Low Extremity subscale of the Stroke Rehabilitation Assessment of Movement (LE-STREAM), the Mobility subscale of STREAM (Mob-STREAM), the Functional Ambulation Category (FAC), the Barthel Index (BI), the Postural Assessment Scale for Stroke Patients (PASS), and the Modified Ashworth Scale (MAS) were administered by a blinded rater at baseline, posttreatment (8wk), and follow-up (12wk). RESULTS: Twenty-three participants completed the study protocol and all outcome measurements. No preexisting group differences between the experimental group (n=11) and the control group (n=12) were found on demographic and clinical variables. Compared with baseline, the experimental group showed significant improvements at posttreatment and follow-up on the LE-STREAM, Mob-STREAM, FAC, and BI (P<.05) while the control group showed no significant improvements for all outcome measures. As for the between-group comparison, significant differences were seen at follow-up (12wk) on the LE-STREAM, Mob-STREAM, BI, and MAS. CONCLUSIONS: Our findings indicate that an 8-week program of noxious TS combined with a traditional stroke rehabilitation program can improve the LE-related movement and function in patients with stroke for more than 3 months.

Machine Learning in Prediction of Bladder Cancer on Clinical Laboratory Data.

Bladder cancer has been increasing globally. Urinary cytology is considered a major screening method for bladder cancer, but it has poor sensitivity. This study aimed to utilize clinical laboratory data and machine learning methods to build predictive models of bladder cancer. A total of 1336 patients with cystitis, bladder cancer, kidney cancer, uterus cancer, and prostate cancer were enrolled in this study. Two-step feature selection combined with WEKA and forward selection was performed. Furthermore, five machine learning models, including decision tree, random forest, support vector machine, extreme gradient boosting (XGBoost), and light gradient boosting machine (GBM) were applied. Features, including calcium, alkaline phosphatase (ALP), albumin, urine ketone, urine occult blood, creatinine, alanine aminotransferase (ALT), and diabetes were selected. The lightGBM model obtained an accuracy of 84.8% to 86.9%, a sensitivity 84% to 87.8%, a specificity of 82.9% to 86.7%, and an area under the curve (AUC) of 0.88 to 0.92 in discriminating bladder cancer from cystitis and other cancers. Our study provides a demonstration of utilizing clinical laboratory data to predict bladder cancer.

Efficacy of Intra-Articular Injection of Biofermentation-Derived High-Molecular Hyaluronic Acid in Knee Osteoarthritis: An Ultrasonographic Study.

OBJECTIVE: The aim of this study is to evaluate the efficacy of intra-articular injection with HYAJOINT Plus, a biofermentation-derived, high-molecular hyaluronic acid (HA), on the progression of structural changes of cartilage in patients with knee osteoarthritis (OA) by using objectively promised ultrasonography (US) evaluation. DESIGN: In this prospective clinical trial, 56 OA patients completed the study. One single dose of injection of HYAJOINT Plus into the knee cavity was performed. The primary efficacy outcome measure for structural change of knee joint was evaluated by US using a semiquantitative grading system. Secondary efficacy outcome measures included Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) total and subscale scores. All efficacy outcomes were measured at baseline and at first, third, and sixth month following treatment. RESULTS: There were significant US grade-improvement changes of cartilage between baseline and follow-up visits over medial femoral condyle and transverse overall evaluation at 3- and 6-month follow-ups, and over lateral femoral condyle, intercondylar notch, and medial longitudinal area at 6-month follow-up. The improved score change of WOMAC from baseline was significant at 1- and 3-month follow-ups in pain subscale, whereas score change from baseline was significant at 6-month follow-up in total score and all 3 subscale scores. CONCLUSIONS: It was determined that significant improvement was found on cartilage by US after intra-articular injection with high-molecular weight, biological fermentation-derived HYAJOINT Plus. The semiquantitative grading system by US is a promising tool to identify the efficacy on cartilage band after interventions.

Correlation of return to work outcomes and hand impairment measures among workers with traumatic hand injury.

INTRODUCTION: Hand impairment is a common and serious occupational injury among workers because it can affect the outcome to return to work (RTW) and even cause permanent dysfunction. The hand measures can directly describe the primary hand function and limitation. This study investigated the correlation of RTW and the overall hand impairment measures in the workers with traumatic hand injury. METHODS: Ninety-six subjects with occupational hand injury were recruited in this study to answer the RTW questionnaire and received the hand evaluation and motion analysis for their affected hands. RTW outcomes assessed whether the subjects successfully returned to work, either from a job change or salary reduction, and the length of the time it took for them to return to work (TRTW). The hand impairment measures included the hand impairment ratio, total active motion loss, motion area loss, grasp power loss, lateral-pinch power loss, and palmar-pinch power loss. RESULTS: A stepwise regression indicated that grasp power loss was a significant predictor for the length of TRTW. The motion area loss was firstly adopted to show statistically significance with RTW outcomes. Besides, the hand impairment ratio was also found to have mild positive correlation with TRTW significantly. CONCLUSIONS: This study presented the subtle correlation of RTW outcomes and hand impairment measures. Both the strength loss and the motion area loss of the hand showed the significant correlation with RTW outcomes. The findings can point to some practical focuses in occupational rehabilitation for the workers with hand trauma.

Postoperative extremity gangrene in a patient with type 2 diabetes taking SGLT2 inhibitors: A case report.

RATIONALE: Sodium-glucose cotransporter 2 (SGLT2) inhibitors have been approved and marketed since March 2013. The proportion of patients with type 2 diabetes (T2D) taking SGLT2 inhibitors is increasing. The perioperative adverse effects of SGLT2 inhibitors, especially euglycemic diabetic ketoacidosis (euDKA), should be taken into consideration in perioperative patient evaluation in both elective and emergency surgeries. PATIENT CONCERNS: A 57-year-old woman taking SGLT2 inhibitors for T2D developed euDKA after undergoing an emergency orthopedic surgery; the euDKA diagnosis was delayed, thereby causing extremity gangrene. DIAGNOSES: EuDKA was diagnosed based on the presence of strongly positive ketonuria, elevated blood beta-hydroxybutyrate level, and severe metabolic acidosis. INTERVENTION: EuDKA was treated with insulin infusion with dextrose solution and intravenous fluid resuscitation. OUTCOME: Due to a delayed diagnosis of euDKA, the patient received a high-dose vasopressor, which led to limb gangrene and amputation 6 months later. LESSONS: EuDKA is often misdiagnosed due to the absence of hyperglycemia. Serum beta-hydroxybutyrate levels or urinalysis could be used as screening tools for euDKA in patients scheduled for emergency surgery, in order to preoperatively administer rapid fluid resuscitation and insulin infusion with dextrose solution, which should continue postoperatively along with serum beta-hydroxybutyrate monitoring.

Assisted exercise improves bone strength in very low birthweight infants by bone quantitative ultrasound.

AIM: To evaluate whether assisted exercise could prevent the development of osteopenia of prematurity, we performed assisted exercise in the study group of very low birthweight (VLBW) premature infants. METHODS: Sixteen premature infants with birthweight below 1500 g were enrolled in this study and randomly assigned into the exercise (n = 8) and control (n = 8) groups. Assisted exercise involved full extension and flexion range of motion of the upper and lower extremities by a trained nurse with a schedule of 5 days a week for a total of 4 weeks. Bone strength was determined by quantitative ultrasound measurement of tibial bone speed of sound every 2 weeks during the study period. RESULTS: No difference in gender, birthweight, and gestation age between the exercise and control groups was noted. There was statistically significant less tibial bone speed of sound decrease in the exercise group on the sixth and eighth week of life. During the study period, there were no statistically significant differences in blood biochemistry data, including calcium, phosphorus, magnesium, alkaline phosphatase, osteocalcin and osteoprotegerin, between the two groups. CONCLUSIONS: This study revealed that early assisted exercise could improve bone strength in very low birthweight infants. The biochemical markers of bone metabolism, osteocalcin and osteoprotegerin, could not be the indicators for early diagnosis of osteopenia of prematurity.

Effects of different stretching techniques on the outcomes of isokinetic exercise in patients with knee osteoarthritis.

We recruited 132 subjects with bilateral knee osteoarthritis (Altman Grade II) to compare the effects of different stretching techniques on the outcomes of isokinetic muscle strengthening exercises. Patients were randomly divided into four groups (I-IV). The patients in Group I received isokinetic muscular strengthening exercises, Group II received bilateral knee static stretching and isokinetic exercises, Group III received proprioceptive neuromuscular facilitation (PNF) stretching and isokinetic exercises, and Group IV acted as controls. Outcomes were measured by changes in Lequesne's index, range of knee motion, visual analog pain scale, and peak muscle torques during knee flexion and extension. Patients in all the treated groups experienced significant reductions in knee pain and disability, and increased peak muscle torques after treatment and at follow-up. However, only patients in Groups II and III had significant improvements in range of motion and muscle strength gain during 60 degrees/second angular velocity peak torques. Group III demonstrated the greatest increase in muscle strength gain during 180 degrees/second angular velocity peak torques. In conclusion, stretching therapy could increase the effectiveness of isokinetic exercise in terms of functional improvement in patients with knee osteoarthritis. PNF techniques were more effective than static stretching.

Immediate responses of multi-focal low level laser therapy on quadriceps in knee osteoarthritis patients.

Low-level laser therapy (LLLT) applying on knee osteoarthritis (OA) patients has shown positive outcomes in analgesic effect and functional recovery. However, few studies applied such therapy on large area of quadriceps muscle in these patients. The aim of this study was to evaluate immediate effect of multi-focal LLLT on quadriceps of knee OA patients in pain and functional performance. Fifty-one participants with knee OA were enrolled and evaluated before (T1) and immediately after intervention (T2) by knee joint pain in numeric rating scale (NRS), walking speed, timed five-chair stands, and quadriceps strength by isokinetic dynamometer. Intervention with two multi-focal Gallium-Aluminum-Arsenide laser devices, each device with 36 laser diodes (wavelength 808 ± 10 nm, continuous, mean power 50 mW, 30 minutes), applied simultaneously over bilateral quadriceps with a total dose of 180 J for each thigh. The multi-focal LLLT significantly improved knee joint pain as measured by the NRS (54% reduction), timed five-chair stands, and walking speed (P < .05). Knee extensor strength also increased in terms of peak torque and force of concentric and eccentric contraction as measured by isokinetic dynamometer (P < .05). In conclusion, single-session multi-focal LLLT on quadriceps in knee OA patients has immediate beneficial effect on knee pain reduction, quadriceps strengthening and functional performance recovery. Long-term effect requires further investigation. Multi-focal LLLT on quadriceps might serve as an alternative non-invasive treatment option in these patients.

Prediction of hand function after occupational hand injury by evaluation of initial anatomical severity.

PURPOSE: To examine the relationship between initial anatomic severity evaluated by the Hand Injury Severity Scoring (HISS) system and recovered hand function evaluated by the Purdue Pegboard after occupational hand injury. METHOD: In the retrospective cohort study, 95 patients hospitalized between 1 January 2000 and 31 December 2003 for surgery due to occupational hand injury were recruited. The HISS scores were obtained by chart review by a surgeon. The Purdue Pegboard was performed at least 6 months after the injury by well-trained occupational therapists. The Purdue Pegboard scores were compared with the initial HISS scores by simple regression, multiple regression and logistic regression analysis. RESULTS: The total HISS score was negatively correlated with scores of the Purdue Pegboard subtests, including injured-hand, both-hands, and assembly. The risk of having low injured-hand score (<13) was significantly increased in workers with initial major severity (HISS >or= 101), with OR 9.57 (95% CI 1.4-94.8). The risk of having low both-hands score (<10) was significantly increased in workers with initial severe and major severity (HISS of 51-100 and >or=101), with OR 4.5 (95% CI 1.1-21.8) and OR 25 (95% CI 3.5-263). The risk of having low assembly score (<25) was significantly increased in workers with initial major severity (HISS >or= 101), with OR 9.0 (95% CI 1.3-72.5). CONCLUSION: The study showed that after occupational hand injury, initial anatomic severity evaluated by the HISS system could predict hand function after recovery.

Comparison of Visual Outcome and Morphologic Change between Different Surgical Techniques in Idiopathic Epiretinal Membrane Surgery.

PURPOSE: To investigate the morphological and functional outcomes of idiopathic epiretinal membrane (ERM) surgery between three different surgical techniques: ERM peeling only, whole-piece ILM peeling, and maculorrhexis ILM peeling. PATIENTS AND METHODS: This is a retrospective, consecutive, and comparative study enrolling 60 patients from Kaohsiung Medical University Hospital, Kaohsiung, Taiwan. Surgery performed between July 2011 and June 2012 was done with ERM peeling only (group I). ERM peeling and ILM peeling as a whole piece (group II) were performed between July 2012 and July 2013. Surgery performed between August 2013 and December 2014 was done with maculorrhexis ILM peeling (group III). Main outcome measures include visual acuity change (BCVA) and central foveal thickness (CFT). RESULTS: At 12 months postoperation, the mean BCVA in group III was significantly better than in group I and group II. Comparison of CFT reduction between the three groups revealed significantly more reduction in group III than in group II at all postoperative follow-up periods. Eyes with restoration of foveal depression were observed in 52.6% in group I, 52.4% in group III, but only 20% of eyes in group II. None of the eyes in both ILM peeling groups encountered recurrence of macular pucker formation. CONCLUSION: All three techniques can achieve visual acuity improvement and macular thickness reduction. Maculorrhexis ILM peeling achieves more rapid improvement of visual function, better final visual outcome, and a higher rate of normal foveal contour than whole-piece ILM peeling.

Abciximab/Heparin Therapy for Left Ventricular Assist Device Implantation in Patients With Heparin-Induced Thrombocytopenia.

BACKGROUND: Optimal anticoagulation strategy remains uncertain in patients with heparin-induced thrombocytopenia (HIT) and undergoing left ventricular assist device (LVAD) implantation. We describe our protocol of abciximab and heparin in these patients. METHODS: Our protocol is to administer abciximab, 0.25 mg/kg loading dose, followed by continuous infusion of 0.125 µg · kg-1 · min-1 throughout cardiopulmonary bypass. Full-dose heparin is then given with subsequent additional doses to maintain an activated clotting time of 400 seconds or longer. The abciximab infusion is stopped 15 minutes after heparin reversal with protamine, and platelets are transfused. RESULTS: Six patients underwent LVAD implantation with this protocol in our program. HIT was confirmed in 4 patients was suspected in 2, which was negative after the operation. One patient received a HeartMate XVE (Thoratec Corp, Pleasanton, CA) and the others received HeartMate II (Thoratec Corp). There were no thromboembolic complications. One patient required chest reexploration for bleeding and temporary right VAD support. Postoperative anticoagulation with argatroban was restarted on median postoperative day 3 (range, days 1 to 6) and warfarin was started on day 5 (range, days 3 to 12). Median postoperative intensive care unit stay was 9 days (range, 5 to 76 days), and hospital stay was 22 days (range, 18 to 132 days). After the initial LVAD implantation, 1 patient required HeartMate XVE LVAD exchange to HeartMate II and subsequent heart transplant, both of which were performed with the abciximab/heparin protocol. A HeartMate II device was explanted in another patient after myocardial recovery. The remaining 4 patients are alive on device support. CONCLUSIONS: This is the first report of a novel abciximab/heparin protocol for LVAD implantation in patients with HIT. The preliminary results suggest the feasibility and safety of this protocol.

Inhalation of volatile anesthetics via a laryngeal mask is associated with lower incidence of intraoperative awareness in non-critically ill patients.

BACKGROUND: Increased incidence of intraoperative awareness was reported in critically ill patients during major operations, particularly under total intravenous (TIVA) or endotracheal general anesthesia (ETGA). However, the incidence and effect of anesthesia techniques on awareness in generally healthy, non-critically ill patients during operations have yet to receive significant attention. METHODS AND RESULTS: This retrospective matched case-control study was conducted between January 2009 to December 2014. Surgical patients (ASA physical status I-III) whom reported intraoperative awareness during this study period were interviewed and their medical records were reviewed. The potential risk factors for awareness were compared with the non-case matched controls, who were randomly selected from the database. A total of 61436 patients were included and 16 definite cases of intraoperative awareness were identified. Patients who received ETGA and TIVA had significantly higher incidence of developing awareness compared to those who were anesthetized using laryngeal masks (LMA) (P = 0.03). Compared with the matched controls (n = 80), longer anesthesia time was associated with increased incidence of awareness (odds ratio 2.04; 95% CI 1.30-3.20, per hour increase). Perioperative use of muscle relaxant was also associated with increased incidence of awareness, while significantly lower incidence of awareness was found in patients who were anesthetized with volatile anesthetics. CONCLUSIONS: The overall incidence of awareness was 0.023% in the ASA≤ III surgical patients who received general anesthesia. Anesthesia with a laryngeal mask under spontaneous ventilation and supplemented with volatile anesthetics may be the preferred anesthesia technique in generally healthy patients in order to provide a lower risk of intraoperative awareness.
