RESUMO

PURPOSE: Use of biologic or synthetic mesh in hernia repair shifts is based on evolving evidence. Poly-4-hydroxybutyrate (P4HB) biosynthetic mesh is a potential alternative to biologic and synthetic mesh in ventral hernia repair (VHR). This meta-analysis assesses the efficacy of P4HB mesh in clean and contaminated surgical settings. METHODS: Two authors searched literature on PubMed, reviewing titles and abstracts of all articles to determine inclusion eligibility. Post-operative data were compared via transformation method to convert the proportion of patients with the outcome of interest into a suitable quantity for random-effects synthesis using STATA software. RESULTS: Initial search yielded 287 citations. Six studies were included and categorized on whether hernia repairs were conducted in clean (CDC class I) or contaminated cases (CDC class II-IV). The pooled proportion of surgical site infection (SSI), surgical site occurrence (SSO), hernia recurrence, total surgical complications, and reoperation were calculated in 391 clean and 81 contaminated cases. For clean vs. contaminated cases, the following pooled proportions were noted: SSI (2% (CI 0-7%) vs 9% (CI 0-025) (p = 0.03), SSO: 14% (CI 5-25%) vs 35% (CI 22-50%) (p = 0.006), hernia recurrence (8% (CI 1-19%) vs 4% (CI 0-12%) (p = 0.769); surgical complications (17% (CI 6-32%) vs 50% (CI 27-72%) (p = 0.009). Reoperation data were available in 298 clean cases across four studies: 5% (CI 0-15%). CONCLUSIONS: P4HB biosynthetic mesh may be more effective than previously thought, particularly in clean wounds. P4HB may also be superior to biologic mesh when compared to clinical trial data. Further research is necessary for more direct comparison.

RESUMO

Bempegaldesleukin (BEMPEG), a CD122-preferential IL2 pathway agonist, has been shown to induce proliferation and activation of NK cells. NK activation is dependent on the balance of inhibitory and excitatory signals transmitted by NK receptors, including Fc-gamma receptors (FCγRs) and killer immunoglobulin-like receptors (KIRs) along with their KIR-ligands. The repertoire of KIRs/KIR-ligands an individual inherits and the single-nucleotide polymorphisms (SNPs) of FCγRs can influence NK function and affect responses to immunotherapies. In this retrospective analysis of the single-arm PIVOT-02 trial, 200 patients with advanced solid tumors were genotyped for KIR/KIR-ligand gene status and FCγR SNP status and evaluated for associations with clinical outcome. Patients with inhibitory KIR2DL2 and its ligand (HLA-C1) observed significantly greater tumor shrinkage (TS, median change -13.0 vs. 0%) and increased PFS (5.5 vs. 3.3 months) and a trend toward improved OR (31.2 vs. 19.5%) compared to patients with the complementary genotype. Furthermore, patients with KIR2DL2 and its ligand together with inhibitory KIR3DL1 and its ligand (HLA-Bw4) had improved OR (36.5 vs. 19.6%), greater TS (median change -16.1 vs. 0%), and a trend toward prolonged PFS (8.4 vs. 3.6 months) as compared to patients with the complementary genotype. FCγR polymorphisms did not influence OR/PFS/TS.These data show that clinical response to BEMPEG plus nivolumab treatment in the PIVOT-02 trial may be associated with the repertoire of KIR/KIR-ligands an individual inherits. Further investigation and validation of these results may enable KIR/KIR-ligand genotyping to be utilized prospectively for identifying patients likely to benefit from certain cancer immunotherapy regimens.

RESUMO

Over 2 decades of research indicate the significance of racial or ethnic disparities in mental illness in the United States. However, minoritized racial or ethnic groups tend to report overall lower prevalence rates of psychiatric disorders than White adults, although this varies depending on gender and race or ethnicity. We conducted a rigorous and systematic narrative synthesis on the differences in the prevalence rates and symptoms that differ across racial or ethnic women in depression, anxiety, eating disorders, and premenstrual syndrome or premenstrual dysphoric disorder. Seven systematic reviews and meta-analyses that examined racial/ethnic differences in depression and eating disorders were included. No review that examined racial/ethnic differences in anxiety or premenstrual syndrome or premenstrual dysphoric disorder met inclusion criteria. Methodological quality of the reviews, which was determined by the Assessment of Multiple Systematic Reviews criteria, revealed that the results of 5 reviews were rated as critically low confidence, one review was rated as low confidence, and one review was rated as high confidence. Findings were inconsistent across systematic reviews and meta-analyses because of the methodological differences in the original studies. Overall, racially or ethnically minoritized women generally report lower prevalence rates in depressive and eating disorders than the White women; however, they exhibit different or greater symptom presentation that could influence prevalence estimates depending on the diagnostic criteria followed. Methodological considerations are provided to strengthen the literature on racial or ethnic mental health disparities in women.

RESUMO

Objective: Countless communities worldwide are exposed directly and subsequently to the effects of massive-scale collective stressors, from natural disasters to human-caused. In contexts of collective adversity, health care providers who are also members of these communities share and interdependently affect the range of responses their patients have. We aim to conceptualize this spectrum, termed shared trauma, shared resilience, and shared growth. Method: In this metasynthesis, we review the literature on these underacknowledged dynamics globally. We include prior conceptualizations of direct and indirect trauma, collective trauma, cultural context, and the COVID-19 pandemic toward clearer conceptualization of shared mental health in global collective stressor contexts. Results: Most trauma and resilience research focuses on prevailing concepts and measures with questionable cross-cultural applicability. These works usually center on acute, highly distressing threats to physical safety at the individual level. The scarce literature on shared trauma describes it as a rare phenomenon, entailing conflicting messages of narrative accounts within contexts of few cultures with medium to high degrees of individualism. There has been little consideration of other non-Western and indigenous communities with more collectivist values and collective trauma histories. There is limited understanding of these concepts as they pertain to the vast majority of cultures. As a result, shared trauma, resilience, and growth have been poorly conceptualized, differentiated, or empirically researched. Conclusions: We propose uniquely inclusive models of shared trauma, resilience, and growth. These models reflect the cumulative effects and interplay of direct to indirect, acute to chronic, individual to collective, and historic to transgenerational factors influenced by cultural context.

RESUMO

BACKGROUND: It has been known that the type of anesthesia can affect the stress response to surgery in form of hyperglycemia. This study aims to evaluate and compare the influence of general anesthesia (GA) and spinal anesthesia (SA) on pregnant women who are scheduled to undergo cesarean section (CS) and to understand the impact of obstetrical factors on the maternal hyperglycemic-stress response during CS. METHODS: Prospectively, we identified, assessed and followed those pregnant women who were scheduled to undergo elective CS surgery. The included group comprises any women who was scheduled to undergo an elective CS. The preoperative and postoperative blood glucose levels were measured and compared between both groups (GA and SA groups). RESULTS: The study included 302 patients who satisfied the inclusion and exclusion criteria of the study. GA was more commonly utilized in cesarean sections (56.6%) compared with SA (43.4%). The average gestational age at time of delivery was 37.4 weeks. The post-operative readings were significantly higher in the GA group with a mean sugar level of 110.1 mg/dL and a mean sugar level in the SA group of 87.7 mg/dL (P = 0.00). After performing multiple regression analysis, it was revealed that the type of anesthesia is the most independent factor affecting the postoperative sugar level. CONCLUSION: GA causes higher blood glucose concentrations than SA, which indicates that the impact of GA on hormonal stress response and metabolic hemostasis is greater than in SA.

RESUMO

The burden of stroke can be substantially studied by establishing the functional consequences of stroke and its predictors on the population, economy and to guide rehabilitation efforts. This study aims to determine the subtypes, risk factors, and epidemiology of stroke in Jordan. Methods: A retrospective cohort study design was carried out to determine the risk factors and subtypes of stroke during 2017-2018. The study sample included 176 ischemic stroke patients of the King Abdullah University Hospital. Data was collected through medical records, which was then statistically analysed through frequencies and percentages. Results: Total 176 cases were identified out of which 101 (57.38%) were males and 75 (42.61%) were females and male to female ratio was 1.9:1. Hypertension was the commonest risk factor identified (50.56%), followed by diabetes mellitus (19.88%), hyperlipidaemia (15.34%), coronary artery disease (6.25%), atrial fibrillation (4.54%), and past history of stroke (1.13%). Risk factors such as hypertension (p = 0.007), diabetes (p = 0.000), coronary artery disease (p = 0.000) were significantly associated with subtypes of ischemic strokes. Conclusion: The study concludes that mean age of men was higher as compared to women in small vessel occlusion. The risk of ischemic stroke in patients with dyslipidaemia, diabetes mellitus, and hypertension was higher in middle-aged and old patients.

RESUMO

BACKGROUND The current COVID-19 pandemic highlights the importance of the mindful use of financial and human resources. Preventing infections and preserving resources and manpower are crucial in healthcare. It is important to ensure the ability of surgeons and specialized interventionalists to function through the pandemic. Until now, no justified protocol has been reported for the anesthetic management in cesarean section (CS). CASE REPORT A 29-year-old pregnant woman, G2P1 at 37+4 weeks of gestation, was referred to our center on March 28, 2020, after she had tested positive for COVID-19. She was stable and the CS was planned after she reached term. Through spinal anesthesia, CS was conducted. The anesthesia team was protected with full personal protection equipment. The operation was carried out smoothly without complication. A female neonate was delivered and was tested to be negative for COVID-19. No medical staff cross-infection was reported. CONCLUSIONS Special precautions should be considered when pregnant women are undergoing CS. Spinal anesthesia is preferred over general anesthesia.

RESUMO

BACKGROUND: Anesthesiologists prefer using general anesthesia (GA) in Parkinson's disease (PD). However, GA may mask neurological symptoms in the intraoperative period and exacerbate them postoperatively. Furthermore, the anesthetics used in GA have clear interactions with the drugs used to control PD. On the other hand, drugs used in spinal anesthesia (SA) might be safer for patients with PD. The aim of this study is to evaluate the effect of SA and GA in patients with PD who underwent hip fracture repairs. METHODS: Retrospectively, we identified those patients with PD who were admitted due to hip joint fracture. The following information were obtained: demographics, preoperative assessment information of the patients, type of anesthesia, and types of fractures and orthopedic procedures. In addition, intraoperative and postoperative complications were studied. The patients were divided based on the type of anesthesia received and were compared. RESULTS: Ten (8 males) patients with PD who underwent hip fracture surgery included in the study. Six patients received SA and 4 patients received GA. The mean age was 73.2 years. The preoperative assessment was not significant for all patients. Postoperatively, within the inpatient period, 3 out of 4 patients received GA developed complications (two atelectasis and urinary tract infection) while no patient developed complication from the SA group. Postoperative outpatient complications within one-month included 3 out of 4 cases in the GA group and only one complication in the SA group. The mean hospitalization period was 9 days for patients received GA and 5.8 days for patients received SA. CONCLUSION: This study reported less perioperative complications in the SA. Accordingly, further investigations and rp-randomized controlled trials evaluating various anesthetic techniques or drugs are needed.

RESUMO

Peripheral neuropathy is a common neurodegenerative disease, with vastness of inducers and causalities. The acquired form peripheral neuropathy can be caused by traumatic injuries caused by nerve lacerations or compressions. Such injuries are usually followed by Wallerian degeneration, and inflammatory reaction. We present a case of a 33-year-old female with a chronic loss of the ulnar nerve function for 8 years after traumatic laceration. After that, she regained the functions of ulnar nerve after nerve stimulation by peri-ulnar nerve injection of methylprednisolone and lidocaine. The theory behind using steroids is related to the fact that the immune system could induce a secondary injury that interferes with the recovery. Many studies have shown effectiveness in using steroids alone or when combined with other substances on nerve regeneration in animal models. We believe that this is the first report of nerve recovery using local steroidal injections after a traumatic injury.

RESUMO

Preclinical mouse models suggest that the gut microbiome modulates tumor response to checkpoint blockade immunotherapy; however, this has not been well-characterized in human cancer patients. Here we examined the oral and gut microbiome of melanoma patients undergoing anti-programmed cell death 1 protein (PD-1) immunotherapy (n = 112). Significant differences were observed in the diversity and composition of the patient gut microbiome of responders versus nonresponders. Analysis of patient fecal microbiome samples (n = 43, 30 responders, 13 nonresponders) showed significantly higher alpha diversity (P < 0.01) and relative abundance of bacteria of the Ruminococcaceae family (P < 0.01) in responding patients. Metagenomic studies revealed functional differences in gut bacteria in responders, including enrichment of anabolic pathways. Immune profiling suggested enhanced systemic and antitumor immunity in responding patients with a favorable gut microbiome as well as in germ-free mice receiving fecal transplants from responding patients. Together, these data have important implications for the treatment of melanoma patients with immune checkpoint inhibitors.
