    Aim To investigate the efficacy and safety of the single-step surgery in elderly patients with obstructive colorectal cancer. Methods All patients who underwent single-step surgery and primary anastomosis for obstructive colorectal cancer in the period between January 2012 December 2017 were evaluated in this study. The patients were divided into two groups: younger than 65 (Group Young) and older than 65 (Group Old). Demographic data, American Society of Anesthesiologists scores (ASA) scores, comorbidities, preoperative albumin levels, type of surgery, postoperative morbidity and mortality, pathological stages, and overall survival rates were investigated. Results A total of 89 patients were included: 49 (54%) were older than 65 (Group Old). In Group Old, the mean age was 75 (65-97), of which 28 (58.3%) were males. There were 41 patients younger than 65 (Group Young) with the mean age of 52.6 (41-64 years of age), of which 21 (51.2%) were males. There was no difference between groups according to albumin level. There was no statistical difference between two groups according to tumour localization, pathological stage and type of surgery, as well as according to surgical complications. The median overall survival rate was 11 months in both groups (0-66) (p=0.320). Conclusion Meticulous preparation of older patients (correction of anaemia, electrolyte levels and pH ) paves the road for successful surgeries, including single-step resection and primary anastomosis

    © 2019 Elsevier Ltd. All rights reserved.The main aim of this review article was to address the performance of filament wound fibre reinforced polymer (FRP) composite pipes and their critical properties, such as burst, buckling, durability and corrosion. The importance of process parameters concerning merits and demerits of the manufacturing methods was discussed for the better-quality performance. Burst analysis revealed that the winding angle of ±55° was observed to be optimum with minimum failure mechanisms, such as matrix cracking, whitening, leakage and fracture. The reduction of buckling effect was reported in case of lower hoop stress value in the hoop to axial stress ratio against axial, compression and torsion. A significant improvement in energy absorption was observed in the hybrid composite pipes with the effect of thermal treatment. However, the varying winding angle in FRP pipe fabrication was reported as an influencing factor affecting all the aforementioned properties. Almost 90% of the reviewed studies was done using E-glass/epoxy materials for the composite pipe production. By overcoming associated limitations, such as replacing synthetic materials, designing new material combinations and cost-benefit analysis, the production cost of the lightweight FRP composite pipes can be decreased for the real-time applications.Peer reviewe

    © 2022 Asian Pacific Journal of Tropical Medicine.Objective: To determine post-discharge mortality and associated factors of the first-wave multicenter Turkish Thoracic Society (TTD)-TURCOVID study. Methods: In this retrospective cohort study, we analyzed the data of 18 of 26 centers included in the first TTD-TURCOVID study, and 1 112 cases diagnosed with COVID-19 between 11 March and 31 July 2020 participated in the study. All causes of death after COVID-19 discharge were recorded. Results: The mean age of the patients was (51.07±16.93) years, with 57.6% male patients. In the cohort group, 89.1% of COVID-19 treatment locations were hospital wards, 3.6% were intensive care units (ICUs), and 7.2% were community outpatients. In the longterm follow-up, the in-hospital mortality rate was 3.6% (95% CI 2.64.8), the post-discharge mortality rate was 2.8% (95% CI 1.9-3.9), and the total mortality was 6.3% (95% CI 5.0-7.8). After discharge, 63.3% of mortality overall occurred during the first six months. Mortality rates in post-discharge follow-ups were 12.7% (95% CI 8.0-30.6) in cancer patients, 10.8% (95% CI 6.3-22.9) in chronic obstructive pulmonary disease patients, 11.1% (95% CI 4.4-22.7) in heart failure patients, 7.8 (95% CI 3.8-14.3) in atherosclerotic heart disease patients, and 2.3% (95% CI 0.8-5.6) in diabetes mellitus patients. In smokers/ex-smokers, the all-mortality rates were higher than in non-smokers. Conclusions: This multicenter study showed that patients over 65 years of age, males, former/active smoker, ICU stay, lung, heart disease, and malignancy should be followed up for at least the first six months after discharge due to COVID-19

    © 2021 Elsevier LtdThe COVID-19-related death rate varies between countries and is affected by various risk factors. This multicenter registry study was designed to evaluate the mortality rate and the related risk factors in Turkey. We retrospectively evaluated 1500 adults with COVID-19 from 26 centers who were hospitalized between March 11 and July 31, 2020. In the study group, 1041 and 459 cases were diagnosed as definite and highly probable cases, respectively. There were 993 PCR-positive cases (66.2%). Among all cases, 1144 (76.3%) were diagnosed with non-severe pneumonia, whereas 212 (14.1%) had severe pneumonia. Death occurred in 67 patients, corresponding to a mortality rate of 4.5% (95% CI:3.5–5.6). The univariate analysis demonstrated that various factors, including male sex, age ≥65 years and the presence of dyspnea or confusion, malignity, chronic obstructive lung disease, interstitial lung disease, immunosuppressive conditions, severe pneumonia, multiorgan dysfunction, and sepsis, were positively associated with mortality. Favipiravir, hydroxychloroquine and azithromycin were not associated with survival. Following multivariate analysis, male sex, severe pneumonia, multiorgan dysfunction, malignancy, sepsis and interstitial lung diseases were found to be independent risk factors for mortality. Among the biomarkers, procalcitonin levels on the 3rd-5th days of admission showed the strongest associations with mortality (OR: 6.18; 1.6–23.93). This study demonstrated that the mortality rate in hospitalized patients in the early phase of the COVID-19 pandemic was a serious threat and that those patients with male sex, severe pneumonia, multiorgan dysfunction, malignancy, sepsis and interstitial lung diseases were at increased risk of mortality; therefore, such patients should be closely monitored

The objectives of our study were to investigate the association of repurposed antiviral drugs with COVID-19 morbidity. Methods: Patients admitted to 26 different hospitals located in 16 different provinces between March 11–July 18, 2020, were enrolled. Case definition was based on WHO criteria. Patients were managed according to the guidelines by Scientific Board of Ministry of Health of Turkey. Primary outcomes were length of hospitalization, intensive care unit (ICU) requirement, and intubation. Results: We retrospectively evaluated 1,472 COVID-19 adult patients; 57.1% were men (mean age = 51.9 ± 17.7years). A total of 210 (14.3%) had severe pneumonia, 115 (7.8%) were admitted to ICUs, and 69 (4.7%) were intubated during hospitalization. The median (interquartile range) of duration of hospitalization, including ICU admission, was 7 (5–12) days. Favipiravir (n = 328), lopinavir/ritonavir (n = 55), and oseltamivir (n = 761) were administered as antiviral agents, and hydroxychloroquine (HCQ, n = 1,382) and azithromycin (n = 738) were used for their immunomodulatory activity. Lopinavir/ritonavir (β [95% CI]: 4.71 [2.31–7.11]; p = 0.001), favipiravir (β [95% CI]: 3.55 [2.56–4.55]; p = 0.001) and HCQ (β [95% CI]: 0.84 [0.02–1.67]; p = 0.046) were associated with increased risk of lengthy hospital stays. Furthermore, favipiravir was associated with increased risks of ICU admission (OR [95% CI]: 3.02 [1.70–5.35]; p = 0.001) and invasive mechanical ventilation requirement (OR [95% CI]: 2.94 [1.28–6.75]; p = 0.011). Conclusion: Our findings demonstrated that antiviral drugs including lopinavir, ritonavir, and favipiravir were associated with negative clinical outcomes such as increased risks for lengthy hospital stay, ICU admission, and invasive mechanical ventilation requirement. Therefore, repurposing such agents without proven clinical evidence might not be the best approach for COVID-19 treatment
