RESUMO
BACKGROUND: Diabetes mellitus is a significant modulator of postoperative outcomes and is an important risk factor in the patient selection process. We aimed to investigate the effect of diabetes mellitus and use of insulin on outcomes after colorectal resection using a national cohort. METHODS: Adults with a recorded colorectal resection in England between 2010 and 2020 were identified from Hospital Episode Statistics data linked to the Clinical Practice Research Database. The primary outcome was 90-day mortality. Secondary outcomes included hospital length of stay (LOS) and readmission within 90 days. RESULTS: Of the 106 139 (52 875, 49.8% male) patients included, diabetes mellitus was prevalent in 10 931 (10.3%), 2145 (19.6%) of whom had a record of use of insulin. Unadjusted 90-day mortality risk was 5.7%, with an increased adjusted hazard ratio (aHR) for people with diabetes mellitus (aHR 1.28, 95% confidence interval [CI] 1.19-1.37, P<0.001). This risk was higher in both people with diabetes using insulin (aHR 1.51, 95% CI 1.31-1.74, P<0.001) and not using insulin (aHR 1.22, 95% CI 1.13-1.33, P<0.001), compared with those without diabetes. Ninety-day readmission occurred in 20 542 (19.4%) patients and this was more likely in those with diabetes mellitus (aHR 1.23, 95% CI 1.18-1.29, P<0.001). Median (inter-quartile range) LOS was 8 (5-15) days and was higher in people with diabetes mellitus (adjusted time ratio 1.10, 95% CI 1.08-1.11, P<0.001). CONCLUSIONS: People with diabetes mellitus undergoing colorectal resection are at a higher risk of 90-day mortality, prolonged LOS, and 90-day readmission, with use of insulin associated with additional risk.

BACKGROUND: There is increasing evidence to suggest vitamin D plays a role in immune and vascular function; hence, it may be of biological and clinical relevance for patients undergoing major surgery. With a greater number of randomised studies being conducted evaluating the impact of vitamin D supplementation on surgical patients, it is an opportune time to conduct further analysis of the impact of vitamin D on surgical outcomes. METHODS: MEDLINE, EMBASE and the Cochrane Trials Register were interrogated up to December 2023 to identify randomised controlled trials of vitamin D supplementation in surgery. The risk of bias in the included studies was assessed using the Cochrane Risk of Bias tool. A narrative synthesis was conducted for all studies. The primary outcome assessed was overall postoperative survival. RESULTS: We screened 4883 unique studies, assessed 236 full-text articles and included 14 articles in the qualitative synthesis, comprising 1982 patients. The included studies were highly heterogeneous with respect to patient conditions, ranging from open heart surgery to cancer operations to orthopaedic conditions, and also with respect to the timing and equivalent daily dose of vitamin D supplementation (range: 0.5-7500 mcg; 20-300 000 IU). No studies reported significant differences in overall survival or postoperative mortality with vitamin D supplementation. There was also no clear evidence of benefit with respect to overall or intensive care unit length of stay. DISCUSSION: Numerous studies have reported the benefits of vitamin D supplementation in different surgical settings without any consistency. However, this systematic review found no clear evidence of benefit, which warrants the supposition that a single biological effect of vitamin D supplementation does not exist. The observed improvement in outcomes in low vitamin D groups has not been convincingly proven beyond chance findings. TRIAL REGISTRATION NUMBER: CRD42021232067.

Early changes in lung cancer care can affect survival. Given the decrease in diagnosis during lockdowns, we calculated their impact on survival using National Lung Cancer Audit data. Percentage survival and HRs for death were compared between 2019 and lockdown periods of 2020. Decreased survival was observed from the first national lockdown onwards and within 90 days of diagnosis. HRs were highest for people diagnosed at the end of 2020 at 1.26 (95% CI 1.20 to 1.32) for death within 90 days and 1.51 (95% CI 1.42 to 1.60) for death between 91 and 270 days. Further work is needed on measures to mitigate this impact.

BACKGROUND: The COVID-19 pandemic has caused significant disruption to health-care services and delivery worldwide. The impact of the pandemic and associated national lockdowns on lung cancer incidence in England have yet to be assessed. RESEARCH QUESTION: What was the impact of the first year of the COVID-19 pandemic on the incidence and presentation of lung cancer in England? STUDY DESIGN AND METHODS: In this retrospective observational study, incidence rates for lung cancer were calculated from The National Lung Cancer Audit Rapid Cancer Registration Datasets for 2019 and 2020, using midyear population estimates from the Office of National Statistics as the denominators. Rates were compared using Poisson regression according to time points related to national lockdowns in 2020. RESULTS: Sixty-four thousand four hundred fifty-seven patients received a diagnosis of lung cancer across 2019 (n = 33,088) and 2020 (n = 31,369). During the first national lockdown, a 26% reduction in lung cancer incidence was observed compared with the equivalent calendar period of 2019 (adjusted incidence rate ratio [IRR], 0.74; 95% CI, 0.71-0.78). This included a 23% reduction in non-small cell lung cancer (adjusted IRR, 0.77; 95% CI, 0.74-0.81) and a 45% reduction in small cell lung cancer (adjusted IRR, 0.55; 95% CI, 0.46-0.65) incidence. Thereafter, incidence rates almost recovered to baseline, without overcompensation (adjusted IRR, 0.96; 95% CI, 0.94-0.98). INTERPRETATION: The incidence rates of lung cancer in England fell significantly by 26% during the first national lockdown in 2020 and did not compensate later in the year.

Conference proceedings are widely available and may represent the only report of given research. Poor reporting of randomized controlled trials (RCTs) in conference abstracts may impede interpretability. In 2008, the Consolidating Standards of Reporting Trials group published minimum standards for RCT reporting in conference abstracts (CONSORT-A). We sought to evaluate the reporting quality of abstracts presented at major international cardiothoracic conferences. Abstracts were retrieved for the annual meetings of 5 cardiothoracic societies over 3 consecutive years (2016 to 2018). After screening, those reporting on RCTs were scored by 2 independent reviewers against the 17-item CONSORT-A checklist. The primary endpoint was the total number of checklist criteria reported in individual abstracts. Statistical analysis was performed using STATA ICv16. Of 3233 screened abstracts, 100 (3.1%) reported on RCTs. Average checklist adherence was 35% (median 6/17 items, IQR 2-15) across abstracts. Author contact (nâ¯=â¯0), funding disclosures (nâ¯=â¯3, 2.9%) and randomization methodology (nâ¯=â¯5, 4.8%) were the least-frequently reported. There was no statistically-significant difference in terms of reporting quality between conferences (nâ¯=â¯0.07) or years (pâ¯=â¯.06). Trial registration, word count (>300), multicentre trial design and mention of CONSORT in the abstract were associated with higher reporting quality. Reporting quality was not associated with successful full-length publication within 2 years (pâ¯=â¯.33). The reporting quality of abstracts of RCTs presented at international cardiothoracic conferences is poor when benchmarked against the CONSORT-A standards. This highlights an area for targeted improvement.

OBJECTIVES: Uniportal (U-VATS) pneumonectomy in lung cancer patients remains disputed in terms of oncological outcomes, and has not been compared to open approaches previously. We evaluated U-VATS versus open pneumonectomy at a high-volume centre. METHODS: Patients undergoing pneumonectomy for lung cancer between 2014 and 2018 were retrospectively reviewed and divided into two groups based on surgical approach. Propensity-score matching was performed (1:1), and intention-to-treat analysis applied. Overall survival, operative time, intraoperative blood loss, hospital-stay and readmission, pain, time to adjuvant therapy, morbidity and mortality were tested. Statistical analysis was performed using SAS version 9.4 (SAS Institute Inc. NC) RESULTS: 341 patients underwent pneumonectomy; 23 patients with small-cell lung cancer were excluded, thus 318 patients were submitted to surgery by either U-VATS (n = 54) or open (n = 264). After matching, 52 patients were selected from each group. Five patients (9.2%) in the uniportal group required conversion. There was no significant difference in intraoperative outcomes, complication rates, readmission rates or mortality. The U-VATS group experienced significantly shorter hospital stay (mean ± SD; 6.7 ± 2.7 vs 9.1 ± 2.3 days, p < 0.001) and reported less pain postoperatively (p < 0.0001). Adjuvant chemotherapy was initiated sooner after U-VATS (38.1 ± 8.4 vs 50.8 ± 11.5 days, p < 0.0001). Overall survival appeared to be superior in U-VATS when pathology stage was aligned (p = 0.001). CONCLUSIONS: Uniportal VATS is a safe and effective alternative approach to open surgery for pneumonectomy in lung cancer. Complications and oncologic outcomes were comparatively similar. U-VATS showed lower postoperative pain, shorter hospital stay and superior overall survival. The study is a preliminary analysis.
