05). Diphenyleneiodonium The total number of dressing changes per patient in the observation group was three to five times, and the total number of dressing changes per patient in the observation group was five to eight times. There was a statistically significant difference between the two groups (p  less then  0.05). The pain score of the observation group was 3.2 ± 0.6 points (2-4 points), and the pain score of the control group was 5.1 ± 0.8 points (4-7 points). The difference between the two groups was statistically significant (p  less then  0.05). There was no recurrence in the observation group and two cases in the control group. Conclusion Local negative pressure closed drainage technology can shorten the patient's healing course and reduce the duration of treatment, reduce the pain of dressing changes, improve prognosis, and have satisfactory therapeutic effect. It is a simple, effective, and safe technology, which is worthy of clinical application.This study was to compare the anticolitis activity of fresh Saengshik (FSS) with heated Saengshik (HSS) with dextran sulfate sodium (DSS)-induced experimental colitis mouse model. Both FSS- and HSS-fed colitis mice exhibited the effects of the increase in the body weight, the alleviation in the colon shortening, and the reduction of the ratio of colon weight to length. However, FSS-fed colitis mice showed a much more significant decrease in DSS-induced tissue damage by mucosal edema and crypt deficiency than did HSS-fed ones. Besides, FSS contributed to decreasing the serum levels of proinflammatory cytokines (tumor necrosis factor-alpha and interleukin-1 beta) and inhibiting the colonic mRNA expressions of these cytokines in colitis tissue of the mice. FSS also resulted in the lower colonic mRNA expression level of inflammation-related inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in colitis mice than did HSS. Overall results confirmed Saengshik, especially FSS, inhibits more effectively against DSS-induced inflammation reaction in colitis mice than HSS.Introduction This study aims to evaluate the impact of first assistant surgeon experience on the outcomes of laparoscopic hepatectomies in a university-affiliated teaching hospital. Methods This is a retrospective study comparing outcomes of laparoscopic hepatectomies with first assistant surgeons of varying experience levels. Three hundred and eighty-five consecutive laparoscopic hepatectomies performed in a tertiary university-affiliated teaching hospital from 2012 to 2018 were included and stratified into three cohorts-Group 1 in which assistants were residents, Group 2 for fellows, and Group 3 for attendings. Baseline clinicopathologic variables and outcome measures were analyzed using the augmented inverse probability of treatment weighting approach, which is a propensity score-based method that combines aspects of covariate adjustment and inverse probability weighting. Results Group 3 comprised a greater proportion of advanced- and expert-level surgeries based on the Iwate criteria; 33.8%, 32.2%, and 46.0% of patients underwent advanced- and expert-level surgeries in Groups 1, 2, and 3, respectively. Group 3 had consistently higher operative times as well as more frequent use and longer duration of Pringle's maneuver (P  less then  .05). The median operative times for Groups 1, 2, and 3 were 195, 195, and 290 minutes, respectively. Pringle's maneuver was applied in 26.9%, 33.9%, and 60.2% of patients with a corresponding median duration of 35, 36, and 45 minutes, respectively. None of the other perioperative and postoperative outcomes demonstrated statistically significant differences. Conclusion With an appropriate selection of cases, participation of residents as first assistants in laparoscopic hepatectomies can be encouraged without compromise in perioperative outcomes.Background To analyze the rate of methicillin-resistant Staphylococcus aureus (MRSA), gram-negative, and polymicrobial infections in open fractures, measure the efficacy of the current open fracture antibiotic regimen against these infections, identify the most effective agent(s) to cover these infections, and analyze risk factors for infection. Methods We examined retrospectively 451 patients with open fractures from January 2008 to December 2012 who were treated at our facility. Positive cultures during surgical debridement after wound closure defined an infection. Infecting organisms and their antibiotic sensitivities were identified through microbiology culture reports. Rates of MRSA, gram-negative, and polymicrobial infections were determined. The efficacy of the current regimen (cefazolin and gentamicin) was calculated against gram-positive and gram-negative organisms. Efficacy profiles against infectious organisms were calculated for all commonly tested antibiotics. Patient factors, injury characteristeasing compared with historical cohorts. With the sensitivity of early generation cephalosporins being relatively poor against gram-positive organisms, the present antibiotic regimen for open, long-bone fractures may need to be reconsidered with these emerging trends.Objective Symptoms and clinical signs of decreased saliva secretion are a common after cancer therapy. The goal of this research is to systematically review the evidence about the efficacy of photobiomodulation therapy (PBMT) for the management of cancer treatment-related xerostomia or salivary hypofunction. Methods PubMed was searched for articles investigating the clinical effects of PBMT on cancer therapy-related xerostomia or hyposalivation. The publications that met the eligibility criteria were evaluated for the quality of the study design, physical parameter setting reproducibility, specifics of the treatment protocol, clinical outcomes, and adverse effects. The strongest evidence was given a heavier weight in the overall conclusions. link2 Results A total of 314 articles were identified, and 5 controlled trials were included in this systematic review. Most of the studies were in head and neck cancer patients treated with radiotherapy (RT) or radiochemotherapy (RT-CT), and one study was in dry mouth associated with hematopoietic stem cell transplantation (HSCT). Data showed conflicting results for either prevention or treatment of RT- or RT-CT-induced dry mouth or hyposalivation. The data for HSCT-related dry mouth were positive. Conclusions Despite positive preliminary outcomes in most of the trials, it is too early to confidently determine the efficacy of PBM for cancer therapy-related hyposalivation or xerostomia.BACKGROUND Human milk oligosaccharides (HMO) have been recognized for the protective effects they may elicit among high risk infants. One HMO, disialyllacto-N-tetraose (DSLNT), has been shown to reduce the risk for developing necrotizing enterocolitis in preterm infants. RESEARCH AIMS To measure DSLNT content in the human milk from mothers of preterm infants, and (1) assess variability; (2) establish correlations between maternal factors and/or an infant's risk for developing necrotizing enterocolitis; and (3) determine the effect of pasteurization. METHODS DSLNT was measured in 84 samples of preterm milk, in human donor milk, and in Holder and flash pasteurized samples. Preterm infant outcomes were assessed by medical record review. RESULTS DSLNT content of mother's own milk was highly variable and decreased significantly with increasing postnatal age. Four preterm infants (6.7%) developed necrotizing enterocolitis (Bell stage II or greater), 4 (6.7%) developed spontaneous intestinal perforation, and 1 developed both. link3 DSLNT z-score was below the age-specific M within 8 (89%) of the 9 milk samples from mothers whose babies developed necrotizing enterocolitis (p = 0.039), but the DSLNT content did not differ between infants with necrotizing enterocolitis, spontaneous intestinal perforation, or neither condition (p > 0.1). DSLNT levels were significantly reduced in samples of donor milk compared to mothers' own milk (p = 0.0051). Pasteurization did not significantly reduce DSLNT content. CONCLUSIONS DSLNT content of human milk is variable and may be lower in milk from mothers whose infants developed necrotizing enterocolitis. DSLNT content is unaffected by flash or Holder pasteurization.Opioid addiction and overdose are at record levels in the United States. This is driven, in part, by their widespread prescription for the treatment of pain, which also increased opportunity for diversion by sensation-seeking users. Despite considerable research on the neurobiology of addiction, treatment options for opioid abuse remain limited. Mood disorders, particularly depression, are often comorbid with both pain disorders and opioid abuse. The endogenous opioid system, a complex neuromodulatory system, sits at the neurobiological convergence point of these three comorbid disease states. We review evidence for dysregulation of the endogenous opioid system as a mechanism for the development of opioid addiction and/or mood disorder. Specifically, individual differences in opioid system function may underlie differences in vulnerability to opioid addiction and mood disorders. We also review novel research, which promises to provide more detailed understanding of individual differences in endogenous opioid neurobiology and its contribution to opioid addiction susceptibility. Expected final online publication date for the Annual Review of Neuroscience, Volume 43 is July 8, 2020.

However, caregivers and loved ones also require significant support and must work to reimagine their relationship with one another. Objectives We sought to develop a dyadic version of the reintegration model that delineates key parts of the adjustment process that occur between the patient and another significant person rather than as two separate individuals. Methods We refined an initial conceptual model of this dyadic process with findings from a narrative literature review on spousal dyadic mutuality. We assessed emergent themes regarding dyadic adjustment from the literature for their fit with our original reintegration model and through consensus discussion, applied the findings to a final proposed conceptual model of dyadic reintegration at the end of life. Results Examples of dyadic adjustment in the literature relate to the comprehension, creative adaptation, and reintegration processes described in the original reintegration model. Evidence also supported three substantive additions in the new dyadic model (1) shared understanding that the harmony of the dyad is interrupted; (2) consideration of the "we" (the dyad) and the "I" (the individual) in mutual reflection to create a shared narrative; and (3) emphasis on relationship as a factor impacting adjustment processes. Conclusions Available evidence supports interdependent relationships between members of dyads for the three adaptation processes of comprehension, creative adaptation, and reintegration in the model. This dyadic reintegration model can be useful in clinical practice to support dyads facing life-limiting illness.
