ABSTRACT

INTRODUCTION: Implementing perioperative interventions such as enhanced recovery pathways (ERPs) has improved short-term outcomes and minimized length of stay. Preliminary evidence suggests that adherence to the enhanced recovery after surgery protocol may also enhance 5-year cancer-specific survival (CSS) in colorectal cancer surgery. This retrospective study presents long-term survival outcomes and disease recurrence from a high-volume, single-center practice.

METHODS: All patients over 18 years of age diagnosed with rectal adenocarcinoma and undergoing elective minimally invasive surgery (MIS) were retrospectively reviewed between February 2005 and April 2018. Relevant data were extracted from Mayo electronic records and securely stored in a database. Short-term morbidity and long-term oncological outcomes were compared between patients enrolled in ERP and those who received non-enhanced care.

RESULTS: Overall, 600 rectal cancer patients underwent MIS, of whom 320 (53.3%) were treated according to the ERP and 280 (46.7%) received non-enhanced care. ERP was associated with a decrease in length of stay (3 vs. 5 days; p < 0.001) and less overall complications (34.7 vs. 54.3%; p < 0.001). The ERP group did not show an improvement in overall survival (OS) or disease-free survival (DFS) compared with non-enhanced care on multivariable (non-ERP vs. ERP OS: hazard ratio [HR] 1.268, 95% confidence interval [CI] 0.852-1.887; DFS: HR 1.050, 95% CI 0.674-1.635) analysis.

CONCLUSION: ERP was found to be associated with a reduction in short-term morbidity, with no impact on long-term oncological outcomes, such as OS, CSS, and DFS.

ABSTRACT

BACKGROUND: PANELVIEW is an instrument for evaluating the appropriateness of the process, methods, and outcome of guideline development and the satisfaction of the guideline group with these steps.

OBJECTIVE: To evaluate the guideline development process of the German guideline on the treatment of patients with severe/multiple injuries (‘German polytrauma guideline’) from the perspective of the guideline group, and to identify areas where this process may be improved in the future.

METHODS: We administered PANELVIEW to the participants of the 2022 update of the German polytrauma guideline. All guideline group members, including delegates of participating medical societies, steering group members, authors of guideline chapters, the chair, and methodological lead, were invited to participate. Responses were analysed using descriptive statistics. Comments received were categorised by domains/items of the tool.

RESULTS: After the first, second, and last consensus conference, the guideline group was invited via email to participate in a web-based survey. Response rates were 36% (n/N = 13/36), 40% (12/30), and 37% (20/54), respectively. The mean scores for items ranged between 5.1 and 6.9 on a scale from 1 (fully disagree) to 7 (fully agree). Items with mean scores below 6.0 were related to (1) administration, (2) consideration of patients’ views, perspectives, values, and preferences, and (3) the discussion of research gaps and needs for future research.

CONCLUSION: The PANELVIEW tool showed that the guideline group was satisfied with most aspects of the guideline development process. Areas for improvement of the process were identified. Strategies to improve response rates should be explored.

ABSTRACT

BACKGROUND: In Japan, comprehensive cancer statistics data have been collected through national cancer registries, but these data are rarely summarized and reported in research articles.

METHODS: Here, we compiled the national registry data on malignant tumors originating from gynecologic organs (ovary, corpus uteri, cervix uteri) in Japan.

RESULTS: The number of new patients in 2019 was 13,380, 17,880, and 10,879, respectively, and the number of deaths in 2021 was 5081, 2741, and 2894, respectively. Compared with 40 years ago, the incidence of ovarian cancer has tripled, the incidence of uterine corpus cancer (mainly endometrial cancer) has increased eightfold, the mortality rate of uterine corpus cancer has tripled, and the incidence of cervical intraepithelial cancer has increased ninefold in data standardized by the world population. Compared with the United States, the incidence rate of ovarian cancer has overtaken and the mortality rate of uterine corpus cancer is the same, while both the incidence and mortality rates of cervical cancer are higher in Japan.

CONCLUSION: The incidence of gynecologic cancer is increasing significantly in Japan.

ABSTRACT

OBJECTIVE: To analyze the application value of damage control strategies combining pre-hospital emergency treatment with in-hospital treatment for multiple injuries in treating pelvic fracture complicated by multiple injuries.

METHODS: 120 patients with pelvic fracture complicated by multiple injuries admitted to our hospital from January 2020 to January 2023 were selected and divided into a damage control group (early temporary reduction after resuscitation, n = 60) and a control group (no reduction and resuscitation only, n = 60) by treatment methods. The control group was treated with conventional methods, while the damage control group was treated with the damage control strategy combining pre-hospital emergency treatment combined with in-hospital treatment in addition to conventional methods. The mortality rate, complication rate, fracture reduction quality, long-term efficacy, and patient satisfaction of the two groups were compared.

RESULTS: The mortality rate of the damage control group was lower than that of the control group, and the difference has statistical significance (P<0.05); the incidence of infection, DIC, and MODS of the damage control group were lower than that of the control group, with the difference being statistically significant (P<0.05); the incidence of ARDS in the two groups is not that different (P>0.05); the fracture reduction quality and long-term therapeutic effect of patients in the two groups were statistically different, with the damage control group outperforming the control group in both aspects; the difference between the two groups in terms of patient satisfaction was statistically significant (P<0.05), with the patient satisfaction of the damage control group being higher than that of the control group.

CONCLUSION: For patients with pelvic fracture, the application of the damage control strategy combining pre-hospital emergency treatment and in-hospital treatment is a boon to the standardization of the treatment process, the improvement of the treatment success rate and fracture reduction quality and the reduction of complications, and therefore is worth promoting in clinical practice. the early application of external fixation has helped with the definitive reduction at a time when the patuent was stable.

ABSTRACT

Recurrent vaginitis is a leading reason for visiting a gynaecologist, with bacterial vaginosis (BV) and vulvovaginal candidiasis (VVC) being the most common diagnoses. Reasons and mechanisms behind their recurrent nature are poorly understood. We conducted a genome-wide association study (GWAS) to find possible genetic risk factors for recurrent vaginitis using data from a large population-based biobank, the Estonian Biobank. The study included 6870 cases (at least two episodes of vaginitis) and 5945 controls (no vaginitis episodes). GWAS approach included single marker and gene-based analyses, followed by functional annotation of associated variants and candidate gene mapping.In single marker analysis, one statistically significant (P = 7.8 × 10^-9) variant rs1036732378 was identified on chromosome 10. The gene-based association analysis identified one gene, KRT6A, that exceeded the recommended significance threshold (P = 2.6 × 10^-6). This is a member of the keratin protein family and is expressed during differentiation in epithelial tissues.Functional mapping and annotation of genetic associations by using adjusted significance level identified 22 potential risk loci that may be associated with recurrent vaginitis phenotype. Comparison of our results with previous studies provided nominal support for LBP (associated with immune response to vaginal bacteria) and PRKCH genes (possible role in keratinocyte differentiation and susceptibility to candidiasis).In conclusion, this study is the first highlighting a potential role of the vaginal epithelium in recurrent vaginitis.

ABSTRACT

BACKGROUND: Current literature highlights the difficulty in identifying which pelvic floor muscle (PFM) functions are correlated with urinary incontinence (UI).

AIM: In this study, we compared parameters of PFM function (strength, endurance, tone, control, reaction, and/or coordination) according to continence status in women (presence or absence, type and/or severity of urinary incontinence).

EVIDENCE ACQUISITION: A systematic review was conducted following the 2020 PRISMA guidelines. Three databases (Pubmed, Web of Science, and LiSSa) were searched from inception to December 31, 2021. Assessment of risk of bias was performed using the Joanna Briggs Institute critical appraisal checklist.

EVIDENCE SYNTHESIS: The initial research yielded 4733 studies. Forty-two studies met the inclusion criteria, including 4015 participants. No statistical association was found between PFM function and the presence or absence of UI, the different type of UI or the different levels of severity of UI. The heterogeneity in methodologies and analyzes of the results only with the P-value are important limitations of this review.

CONCLUSION: It appears that muscle function is not always associated with presence or absence of UI. No association is found between PFM function and type or severity of UI. These results reinforce the need to carry out a bio-psycho-social evaluation of UI that does not only focus on PFM functions. As such, the results reported herein can be considered a resource for more specific research.

ABSTRACT

PURPOSE: In patients with colorectal cancer (CRC), the most important factor to decide the need of adjuvant chemotherapy is the histological lymph node (LN) evaluation. Our work aimed to give a broad view over the use of methylene blue and its consequences in the number of lymph node harvest.

METHODS: PUBMED, WEB OF SCIENCE and EMBASE databases were consulted, retrieving clinical trials, which mentioned the used of intra-arterial methylene blue in patients with colorectal cancer.

RESULTS: Eighteen clinical trials analyzing the use of intra-arterial methylene blue in specimens of colorectal cancer were selected. The articles show a statistical difference between the use of methylene blue and the classical dissection in both variable at study. The results of the statistical analysis of the lymph node harvest variable demonstrate a significant statistical difference between the group that received methylene blue injection and the group that underwent conventional dissection. There is a significant statistical difference between the experimental and control groups for the ideal lymph node harvest (lymph node harvest count greater than 12).

CONCLUSION: The use of intra-arterial methylene blue revealed a high potential for the quantification of lymph nodes, considering the increase of lymph node harvest and the higher percentage of cases with more than 12 lymph nodes count, albeit the high heterogeneity between the studies in terms of reported results. Future investigations with controlled double blinded studies obtaining better categorized results should be conducted in order to better evaluate this technique and compare it to the current paradigm.

ABSTRACT

Enteral supplementation with arachidonic acid (AA) and docosahexaenoic acid (DHA) in extremely preterm infants has shown beneficial effects on retinopathy of prematurity and pulmonary outcome whereas exclusive DHA supplementation has been associated with increased pulmonary morbidity. This secondary analysis evaluates pulmonary outcome in 204 extremely preterm infants, randomized to receive AA (100 mg/kg/day) and DHA (50 mg/kg/day) enterally from birth until term age or standard care. Pulmonary morbidity was primarily assessed based on severity of bronchopulmonary dysplasia (BPD). Serum levels of AA and DHA during the first 28 days were analysed in relation to BPD. Supplementation with AA:DHA was not associated with increased BPD severity, adjusted OR 1.48 (95 % CI 0.85-2.61), nor with increased need for respiratory support at post menstrual age 36 weeks or duration of oxygen supplementation. Every 1 % increase in AA was associated with a reduction of BPD severity, adjusted OR 0.73 (95 % CI 0.58-0.92). In conclusion, in this study, with limited statistical power, enteral supplementation with AA:DHA was not associated with an increased risk of pulmonary morbidity, but higher levels of AA were associated with less severe BPD. Whether AA or the combination of AA and DHA have beneficial roles in the immature lung needs further research.

ABSTRACT

BACKGROUND: Coronavirus disease 2019 (COVID-19) is a respiratory illness that leads to severe acute respiratory syndrome and various cardiorespiratory complications, contributing to morbidity and mortality. Entropy analysis has demonstrated its ability to monitor physiological states and system dynamics during health and disease. The main objective of the study is to extract information about cardiorespiratory control by conducting a complexity analysis of OSV signals using scale-based entropy measures following a two-month timeframe after recovery.

METHODS: This prospective study collected data from subjects meeting specific criteria, using a Beurer PO-80 pulse oximeter to measure oxygen saturation (SpO2) and pulse rate. Excluding individuals with a history of pulmonary/cardiovascular issues, the study analyzed 88 recordings from 44 subjects (26 men, 18 women, mean age 45.34 ± 14.40) during COVID-19 and two months post-recovery. Data preprocessing and scale-based entropy analysis were applied to assess OSV signals.

RESULTS: The study found a significant difference in mean OSV during illness (95.08 ± 0.15) compared to post-recovery (95.59 ± 1.03), indicating reduced cardiorespiratory dynamism during COVID-19. Multiscale entropy analyses (MSE, MPE, MFE) confirmed lower entropy values during illness across all time scales, particularly at higher scales. Notably, the maximum distinction between illness and recovery phases was seen at specific time scales and similarity criteria for each entropy measure, showing statistically significant differences.

CONCLUSIONS: The study demonstrates that the loss of complexity in OSV signals, quantified using scale-based entropy measures, has the potential to detect malfunctioning of cardiorespiratory control in COVID-19 patients. This finding suggests that OSV signals could serve as a valuable indicator for assessing the cardiorespiratory status of COVID-19 patients and monitoring their recovery progress.

ABSTRACT

OBJECTIVE: In idiopathic inflammatory myopathies, anti-SSa/SSb and anti-Ro52 are associated with interstitial lung disease (ILD), yet few studies have compared their prognostic utility. Our study analyzes clinical phenotypes associated with anti-SSa/SSb and anti-Ro52 positivity in IIM and their association with ILD.

METHODS: We performed a retrospective analysis of IIM patients >18-years-old, seen at Northwell Myositis Center 2007- 2018 who met 2017 EULAR/ACR criteria with available anti-SSa/SSb data. Patients who were anti-SSa/SSb(-) and anti-Ro52(+) were excluded from anti-SSa/SSb subgroup analysis but included in Ro52 subgroup analysis. Organ manifestations, pulmonary function tests (PFTs) and comorbidities were recorded. Statistical analyses included Chi-square, Fisher’s Exact, Wilcoxon Rank Sum, McNemar’s test.

RESULTS: Of 94 patients included in the final analysis, 35% (33/94) were anti-SSa/SSb positive (+). Of 60 patients with anti-Ro52 data, 42% (25/60) were (+). ILD was more common in anti-SSa/SSb (+) versus anti-SSa/SSb negative patients and anti-Ro52(+) versus anti-Ro52 negative patients (58% vs 25%; p = 0.003 and 64% vs.26%; p = 0,004 respectively). Anti-SSa/SSb (+) was not associated with increased ILD severity based on PFTs. Anti-Ro52(+) group had lower DLCO than anti-Ro52(-) (47% vs 68%; p = 0.003). Anti-SSa/SSb positivity did not confer a difference in the frequency of other manifestations. Elevated rates of venous thromboembolism (VTE) (10%-12%) and osteoporosis (13-17%) were observed independent of anti-SSa/SSb or anti-Ro52 status.

CONCLUSION: In IIM anti-SSa/SSb or anti-Ro52 positivity is associated with higher ILD rate. Both assays are useful to confer ILD risk, but anti-Ro52 is more predictive of severe ILD. High frequencies of osteoporosis and VTE were observed in all subgroups.
