Conclusion The current findings are best replicated using time-series data, person-specific network models and clinical samples. Further implications for future research and clinical practice are discussed.Background Oral cavity carcinomas individually are the fifth-leading cause of overall cancer mortality in the Northern Mariana Islands, which is likely a representative statistic for many other betel-nut-endemic Pacific islands. Factors associated with survival have been minimally evaluated in this region. The purpose of this study is to further characterize oral cavity carcinoma outcomes and associated prognostic factors in the United States commonwealth of the Northern Mariana Islands (CNMI). Methods A single-institution retrospective review was undertaken for 81 patients diagnosed with head and neck cancers at the CNMI’s only regional hospital complex from 2005 to 2019. A subset of patients diagnosed with oral cavity carcinoma was further evaluated for survival outcomes. Cox proportional hazard regressions were performed to evaluate for variables associated with survival. Results A majority of patients had cancer of the oral cavity (64/81, 79%). Fifty-five of these patients had sufficient data for review. The average age at the time of diagnosis was 48 and over half were diagnosed with stage IV disease (29/55, 53%). Five-year overall survival (OS) was 49.5% (95% CI, 33.3-63.7%). Factors associated with worse OS were lymph node metastases at presentation (P = .031), higher overall stage (III or IV vs I or II, P = .016), and higher T-stage (III or IV vs I or II, P = .027). Those who used betel nut were diagnosed at a significantly younger age than those who did not (47.2 vs 55.4, P = .001). Conclusions The head and neck cancer burden in the CNMI is dominated by betel nut related oral cavity disease that is characterized by delayed presentations in younger patients and decreased OS. Future studies are indicated to improve health literacy as well as to investigate the potential for screening programs.Background The anterocentral portal is not a standard portal in anterior ankle arthroscopy due to its proximity to the anterior neurovascular bundle. However, it provides certain advantages, including a wide field of vision, and portal changes become redundant. The purpose of this study was to evaluate the neurovascular complications after anterior ankle arthroscopy using the anterocentral portal. Methods We retrospectively identified patients who had undergone anterior ankle arthroscopy with an anterocentral portal at our institution from 2013 to 2018. Medical record data were reviewed and patients were invited for clinical follow-up, where a clinical examination, quantitative sensory testing for the deep peroneal nerve, and ultrasonography of the structures at risk were performed. A total of 101 patients (105 arthroscopies) were identified and evaluated at a mean follow-up of 31.5 ± 17.7 months. Results Leading indications to surgery were heterogeneous and included anterior impingement (48.6%), osteochondranterocentral portal in ankle arthroscopy is safe with a low number of neurovascular injuries and can be recommended as a standard portal. The anterolateral portal remains associated with a high number of injuries to the superficial peroneal nerve. Level of evidence Level III, retrospective cohort study.ackground This study meta-analyzed the literature on possible association of three polymorphisms (-592, -1082, -819) in the interleukin-10 (IL-10) gene with susceptibility to HIV-1 infection. Methods PubMed, EMBASE, MEDLINE and Google Scholar were systematically searched to identify relevant studies in English. Meta-analyses were performed to examine the association of IL-10 polymorphisms -592, -1082, and -819 with susceptibility to HIV-1 infection. Results A significant association between the -592 polymorphism and susceptibility to HIV-1 infection was found in the total population (recessive model, OR = 1.44, 95% CI = 1.06-1.96, P = 0.02; homozygous model, OR = 1.44, 95% CI = 1.02-2.02, P = 0.04). However, these results were not observed in subgroups based on ethnicity. The -1082 polymorphism was significantly associated with susceptibility to HIV-1 infection in Caucasians (OR = 1.30, 95% CI = 1.05-1.62, P = 0.02; recessive model, OR = 1.49, 95% CI = 1.09-2.03, P = 0.01; homozygous model, OR = 1.58, 95% CI = 1.01-2.46, P = 0.04), but not in Asians or the total population. None of the five genetic models suggested a significant association between the -819 polymorphism and HIV-1 infection. AXL1717 mw Conclusion The available evidence indicates that the AA genotype of IL-10 -592 may confer increased susceptibility to HIV-1 infection, and that the AA genotype of -1082 may confer increased susceptibility in Caucasians. In contrast, the -819 polymorphism may not be associated with HIV-1 infection risk. These conclusions should be verified in large, well-designed studies.A do-not-resuscitate (DNR) order is an important end-of-life decision. In Taiwan, family caregivers are also involved in this decision-making process. This study aimed to explore the concerns and experiences regarding DNR decisions among caregivers in Taiwan. Qualitative study was conducted. Convenience sampling was used, and 26 caregivers were recruited whose patients had a DNR order and had received hospice care or hospice home care. Semi-structured interviews were used for data collection, including the previous experiences of DNR discussions with the patients and medical staff and their concerns and difficulties in decision-making. The data analysis was based on the principle of thematic analysis. Four themes were identified (1) Patients The caregivers respected the patients’ willingness and did not want to make them feel like “giving up.” (2) Caregivers’ self They did not want to intensify the patients’ suffering but sometimes found it emotionally difficult to accept death. (3) Other family members They were concerned about the other family members’ opinions on DNR orders, their blame, and their views on filial impiety. (4) Medical staff The information and suggestions from the medical staff were foundational to their decision-making. The caregivers needed the health care professionals’ supports to deal with the concerns from patients and other family members as well as their emotional reactions.
