Routine antibiotics may not be needed to treat uncomplicated right diverticulitis: A retrospective cohort study

We aimed to investigate whether antibiotic administration is necessary for patients with uncomplicated right colonic diverticulitis. Data from patients diagnosed with uncomplicated right colonic diverticulitis, who received inpatient treatment at a single center between January 2019 and January 2021, were retrospectively examined. The patients were divided into two groups according to whether antibiotics were administered. The patients were matched between groups using propensity score matching in a 1:1 ratio using logistic regression with the nearest-neighbor method. The primary study outcome was the length of hospital stay, and the secondary outcomes were time to the introduction of sips of water and a soft diet. The study included 138 patients who received antibiotics and 59 who did not. After propensity score matching, 55 patients were assigned to each treatment group. There was no significant difference between the two groups in terms of age (p = 0.772), sex (p>0.999), body mass index (p = 0.121), prehospital symptom duration (p = 0.727), initial body temperature (p = 0.661), white blood cell count (p = 0.688), or C-reactive protein level (p = 0.337). There was also no statistically significant difference in the length of hospital stay between the no antibiotic and antibiotic groups (3.1±0.7 days vs. 3.0±1.0 days, p = 0.584). Additionally, no significant difference was observed between the no antibiotic and antibiotic groups with respect to time to sips of water (2.1±0.7 days vs. 1.8±0.9 days, p = 0.100) and time to the introduction of a soft diet (2.4±0.8 days vs. 2.1±0.9 days, p = 0.125). The findings suggest that routine antibiotics may be not required for treating patients with uncomplicated right colonic diverticulitis.

Abstract Background Oral switch to linezolid is a promising alternative to standard parenteral therapy (SPT) in Staphylococcus aureus bacteremia (SAB). Methods We conducted a prospective cohort study of all adult cases of SAB between 2013 and 2017 in a Spanish university hospital. We compared the efﬁcacy, safety, and length of hospital stay of patients receiving SPT and those where SPT was switched to oral linezolid between days 3 and 9 of treatment until completion. We excluded complicated SAB and osteoarticular infections. A k-nearest neighbor algorithm was used for propensity score matching with a 2:1 ratio. Results After propensity score matching, we included 45 patients from the linezolid group and 90 patients from the SPT group. Leading SAB sources were catheter related (49.6%), unknown origin (20.0%), and skin and soft tissue (17.0%). We observed no difference in 90-day relapse between the linezolid group and the SPT group (2.2% vs 4.4% respectively; P = .87). No statistically significant difference was observed in 30-day all-cause mortality between the linezolid group and the SPT group (2.2% vs 13.3%; P = .08). The median length of hospital stay after onset was 8 days in the linezolid group and 19 days in the SPT group (P < .01). No drug-related events leading to discontinuation were noted in the linezolid group. Conclusions Treatment of SAB in selected low-risk patients with an oral switch to linezolid between days 3 and 9 of treatment until completion yielded similar clinical outcomes as SPT, allowing earlier discharge from the hospital.

Abstract Background Acute myocardial infarction (AMI) in the very elderly is associated with high morbidity and mortality. Because the majority of study population in clinical researches focusing on the very elderly with AMI were octogenarians, clinical evidences regarding AMI in nonagenarians are sparse. The aim of the present study was to compare in-hospital clinical outcomes of AMI between octogenarians and nonagenarians. Methods We included consecutive 415 very elderly (≥80 years) patients with AMI, and divided into the nonagenarian group (n=38) and the octogenarian group (n=377). Clinical characteristics and in-hospital outcomes were compared between the 2 groups. Furthermore, we used propensity-score matching to find the matched octogenarian group (n=38). Results Percutaneous coronary interventions (PCI) to the culprit of AMI were similarly performed between the nonagenarian (86.8%) and octogenarian (87.0%) groups The incidence of in-hospital death in the nonagenarian group (13.2%) was similar to that in the octogenarian group (14.6%) (P=0.811). The length of hospital stay was significantly shorter in the nonagenarian group (7.4±4.2 days) than that in the octogenarian group (15.4±19.4 days) (P<0.001). After using the propensity-score matching, the incidence of in-hospital death was less in the nonagenarian group (13.2%) than in the matched octogenarian group (21.1%) without reaching statistical significance (P=0.361). The length of hospitalization was significantly shorter in the nonagenarian group (7.4±4.2 days) than in the matched octogenarian group (17.8±37.0 days) (P=0.01). Clinical outcomes Nonagenarian group (n=38) Octogenarian group (n=377) P value In-hospital death, n (%) 5 (13.2) 55 (14.6) 0.811 Length of hospital stay (days) 7.4±4.2 15.4±19.4 <0.001 Length of CCU stay (days) 3.3±2.5 4.7±5.1 0.109 LVEF (%) 48.2±9.2 50.8±13.7 0.152 Peak CPK (U/L) 1424.8±1580.8 1640.1±2394.4 0.912 CCU indicates Coronary care unit; LVEF, Left ventricular ejection fraction; CPK, Creatine kinase. Flow-chart Conclusions The in-hospital mortality of nonagenarians with AMI was comparable to that of octogenarians with AMI. In-hospital outcomes in nonagenarians with AMI may be acceptable as long as acute medical management including PCI to the culprit of AMI is performed. Acknowledgement/Funding None

Objective: Thymosin alpha 1 (Thymosin-α1) is a potential treatment for patients with COVID-19. We aimed to determine the effect of Thymosin-α1 in non-severe patients with COVID-19.Methods: We retrospectively enrolled 1,388 non-severe patients with COVID-19. The primary and secondary clinical outcomes were evaluated with comparisons between patients treated with or without Thymosin-α1 therapy.Results: Among 1,388 enrolled patients, 232 patients (16.7%) received both Thymosin-α1 therapy and standard therapy (Thymosin-α1 group), and 1,156 patients (83.3%) received standard therapy (control group). After propensity score matching (1:1 ratio), baseline characteristics were well-balanced between the Thymosin-α1 group and control group. The proportion of patients that progressed to severe COVID-19 is 2.17% for the Thymosin-α1 group and 2.71% for the control group (p = 0.736). The COVID-19-related mortality is 0.54% for the Thymosin-α1 group and 0 for the control group (p = 0.317). Compared with the control group, the Thymosin-α1 group had significantly shorter SARS-CoV-2 RNA shedding duration (13 vs. 16 days, p = 0.025) and hospital stay (14 vs. 18 days, p < 0.001). No statistically significant difference was found between the Thymosin-α1 group and control group in duration of symptoms (median, 4 vs. 3 days, p = 0.843) and antibiotic utilization rate (14.1% vs. 15.2%, p = 0.768).Conclusion: For non-severe patients with COVID-19, Thymosin-α1 can shorten viral RNA shedding duration and hospital stay but did not prevent COVID-19 progression and reduce COVID-19-related mortality rate.

Abstract Background The aim of the study was to compare the outcome of pure laparoscopic and open simultaneous resection of both the primary colorectal cancer and synchronous colorectal liver metastases (SCLM). Patients and methods From 2000 to 2016 all patients treated by simultaneous resection were assessed for entry in this single center, clinically nonrandomized trial. A propensity score matching was used to compare the laparoscopic group (LAP) to open surgery group (OPEN). Primary endpoints were perioperative and oncologic outcomes. Secondary endpoints were overall survival (OS) and disease-free survival (DFS). Results Of the 82 patients identified who underwent simultaneous liver resection for SCLM, 10 patients underwent LAP. All these consecutive patients from LAP were matched to 10 comparable OPEN. LAP reduced the length of hospital stay (P = 0.044) and solid food oral intake was faster (P = 0.006) in this group. No patient undergoing the laparoscopic procedure experienced conversion to the open technique. No difference was observed in operative time, blood loss, transfusion rate, narcotics requirement, clinical risk score, resection margin, R0 resections rate, morbidity, mortality and incisional hernias rate. The two groups did not differ significantly in terms of the 3-year OS rate (90 vs. 75%; P = 0.842) and DFS rate (60 vs. 57%; P = 0.724). Conclusions LAP reduced the length of hospital stay and offers faster solid food oral intake. Comparable oncologic and survival outcomes can be achieved. LAP is beneficial for well selected patients in high volume centers with appropriate expertise.

Objective Esophagectomy is a high-risk surgical procedure with significant postoperative morbidity and mortality. This study aimed to investigate the risk factors of cervical anastomotic leakage and postoperative mortality. Methods In this retrospective, observational study, we recruited 1010 patients with esophageal cancer. Cox regression analysis was performed to identify factors affecting anastomotic leakage and postoperative mortality. After propensity score matching, the Kaplan–Meier curve was used to evaluate the effect of leakage on postoperative mortality. Results The number of patients with cervical anastomotic leakage, in-hospital mortality, 30-day postoperative mortality, and 60-day postoperative mortality was 194 (19.2%), 13 (1.3%), 12 (1.2%), and 16 (1.6%), respectively. The total length of hospital stay and hospital stay postoperatively were 29.7 ± 21.1 and 21.3 ± 20.3 days, respectively. Diabetes, stage IV, and an upper thoracic tumor were significant risk factors for leakage. Leakage and diabetes were significant risk factors for postoperative mortality. After propensity score matching, leakage also significantly affected postoperative mortality. Conclusions Patients with tumors in the upper thoracic segment of the esophagus may be more prone to developing anastomotic leakage compared with those with tumors in the middle or lower thoracic segment. Anastomotic leakage may prolong the length of hospital stay and increase postoperative mortality.

Abstract Purpose We aimed to compare retrospectively the rates of renal morbidity and mortality in surgical patients receiving 6% HES 130/0.4 to those receiving albumin. Methods From a Japanese nationwide medical database between 2014 and 2016, we identified adults who received HES 130/0.4 (HES group) or albumin (albumin group) as a single colloid solution on the day of surgery. After propensity score matching, the two groups were analyzed with χ2 or Mann Whitney U test. The primary outcome was the incidence of acute kidney injury (AKI). Secondary outcomes included the incidence of renal-replacement therapy, hospital length of stay, in-hospital 30-day mortality, the use of vasoactive agents, and the fluid requirement on the day of surgery. Results Of 76,048 patients in the database, propensity score matching identified 289 matched pairs. There was no statistically significant difference in the incidence of AKI between the HES and the albumin group (15.2% vs. 20.8%, respectively: P = 0.08). The secondary outcomes did not differ between groups except the following. Median hospital stay was 5 days shorter in the HES group (18 vs. 23 days; P < 0.001), and the median net fluid requirement on the day of surgery was 15 mL/kg lower in the HES group (140 vs. 155 mL/kg, respectively; P = 0.01). Conclusions Postoperative renal morbidity and mortality did not differ between patients receiving HES 130/0.4 and those receiving albumin. HES 130/0.4 was associated with shorter hospital stay and less fluid requirement compared to albumin. These findings support the use of 6% HES 130/0.4 for perioperative volume replacement as an alternative to albumin.

Abstract Objective Postoperative pulmonary complications (PPCs) are common incidents associated with an increased hospital stay, readmissions into the intensive care unit (ICU), increased costs, and mortality after cardiac surgery. Our study aims to analyze whether minimally invasive valve surgery (MIVS) can reduce the incidence of postoperative pulmonary complications compared to the full median sternotomy (FS) approach. Methods We reviewed the records of 1076 patients who underwent isolated mitral or aortic valve surgery (80 MIVS and 996 FS) in our institution between January 2015 and December 2019. Propensity score-matching analysis was used to compare outcomes between the groups and to reduce selection bias. Results Propensity score matching revealed no significant difference in hospital mortality between the groups. The incidence of PPCs was significantly less in the MIVS group than in the FS group (19% vs. 69%, respectively; P < 0.0001). The most common PPCs were atelectasis (P = 0.034), pleural effusions (P = 0.042), and pulmonary infection (P = 0.001). Prolonged mechanical ventilation time (> 24 h) (P = 0.016), blood transfusion amount (P = 0.006), length of hospital stay (P < 0.0001), and ICU stay (P < 0.0001) were significantly less in the MIVS group. Cardiopulmonary bypass (CBP), aortic cross-clamping, and operative time intervals were significantly longer in the MIVS group than in the matched FS group (P < 0.001). A multivariable analysis revealed a decreased risk of PPCs in patients undergoing MIVS (odds ratio, 0.25; 95% confidence interval, 0.006–0.180; P < 0.0001). Conclusion MIVS for isolated valve surgery reduces the risk of PPCs compared with the FS approach.

Postoperative Ileus (POI) is one of the most common problems after obstetrics, gynecologic and abdominal surgeries. Sham feeding, such as gum chewing, accelerates the return of bowel function and the length of hospital stay. The present study aims to evaluate the effect of chewing gum on bowel motility in women undergoing post-operative cesarean section. Intervention study was used at the Postpartum Department of Maternity and Children Hospital, KSA. A randomized controlled clinical trial research design. Through a convenience technique, 80 post Caesarian Section (CS) women were included in the study. Data were collected through three tools: Tool (I): Socio-demographic data and reproductive history interview schedule. Tool (II): Postoperative Assessment Sheet. Tool (III): Outcomes of gum chewing and the length of hospital stay. Method: subjects were assigned randomly into two groups of (40) the experimental and (40) the control. Subjects in the study group were asked to chew two pieces of sugarless gum for 30 min/three times daily in the morning, noon, and evening immediately after recovery from anesthesia and in Postpartum Department; while subjects in the control group followed the hospital routine care. Each woman in both groups was tested abdominally using a stethoscope to auscultate the bowel sounds and asked to report immediately the time of either passing flatus or stool. Results: illustrated that a highly statistically significant difference was observed between the two groups concerning their gum chewing outcomes. Where, P = 0.000. The study concluded that gum chewing is safe, well tolerated and appears to be effective in reducing the incidence and consequences of POI following CS.

AbstractThe laparoscopic approach is considered as standard practice in patients with body-tail pancreatic neoplasms. However, only a few randomized controlled trials (RCTs) and propensity score matching (PSM) studies have been performed. Thus, additional studies are needed to obtain more robust evidence. This is a single-centre propensity score-matched study including patients who underwent laparoscopic (LDP) and open distal pancreatectomy (ODP) with splenectomy for pancreatic neoplasms. Demographic, intra, postoperative and oncological data were collected. The primary endpoint was the length of hospital stay. The secondary endpoints included the assessment of the operative findings, postoperative outcomes, oncological outcomes (only in the subset of patients with pancreatic ductal adenocarcinoma-PDAC) and total costs. In total, 205 patients were analysed: 105 (51.2%) undergoing an open approach and 100 (48.8%) a laparoscopic approach. After PSM, two well-balanced groups of 75 patients were analysed and showed a shorter length of hospital stay (P = 0.001), a lower blood loss (P = 0.032), a reduced rate of postoperative morbidity (P < 0.001) and decreased total costs (P = 0.050) after LDP with respect to ODP. Regarding the subset of patients with PDAC, 22 patients were analysed: they showed a significant shorter length of hospital stay (P = 0.050) and a reduction in postoperative morbidity (P < 0.001) after LDP with respect to ODP. Oncological outcomes were similar. LDP showed lower hospital stay and postoperative morbidity rate than ODP both in the entire population and in patients affected by PDAC. Total costs were reduced only in the entire population. Oncological outcomes were comparable in PDAC patients.

Abstract Background Hospitalized patients with COVID-19 demonstrate a higher risk of developing thromboembolism. Anticoagulation (AC) has been proposed for high-risk patients, even without confirmed thromboembolism. However, benefits and risks of AC are not well assessed due to insufficient clinical data. We performed a retrospective analysis of outcomes from AC in a large population of COVID-19 patients. Methods We retrospectively reviewed 1189 patients hospitalized for COVID-19 between March 5 and May 15, 2020, with primary outcomes of mortality, invasive mechanical ventilation, and major bleeding. Patients who received therapeutic AC for known indications were excluded. Propensity score matching of baseline characteristics and admission parameters was performed to minimize bias between cohorts. Results The analysis cohort included 973 patients. Forty-four patients who received therapeutic AC for confirmed thromboembolic events and atrial fibrillation were excluded. After propensity score matching, 133 patients received empiric therapeutic AC while 215 received low dose prophylactic AC. Overall, there was no difference in the rate of invasive mechanical ventilation (73.7% versus 65.6%, p = 0.133) or mortality (60.2% versus 60.9%, p = 0.885). However, among patients requiring invasive mechanical ventilation, empiric therapeutic AC was an independent predictor of lower mortality (hazard ratio [HR] 0.476, 95% confidence interval [CI] 0.345–0.657, p < 0.001) with longer median survival (14 days vs 8 days, p < 0.001), but these associations were not observed in the overall cohort (p = 0.063). Additionally, no significant difference in mortality was found between patients receiving empiric therapeutic AC versus prophylactic AC in various subgroups with different D-dimer level cutoffs. Patients who received therapeutic AC showed a higher incidence of major bleeding (13.8% vs 3.9%, p < 0.001). Furthermore, patients with a HAS-BLED score of ≥2 had a higher risk of mortality (HR 1.482, 95% CI 1.110–1.980, p = 0.008), while those with a score of ≥3 had a higher risk of major bleeding (Odds ratio: 1.883, CI: 1.114–3.729, p = 0.016). Conclusion Empiric use of therapeutic AC conferred survival benefit to patients requiring invasive mechanical ventilation, but did not show benefit in non-critically ill patients hospitalized for COVID-19. Careful bleeding risk estimation should be pursued before considering escalation of AC intensity.
