These simulation studies reveal that MaAsLin 2's linear model preserves statistical power in the presence of repeated measures and multiple covariates, while accounting for the nuances of meta-omics features and controlling false discovery. We also applied MaAsLin 2 to a microbial multi-omics dataset from the Integrative Human Microbiome (HMP2) project which, in addition to reproducing established results, revealed a unique, integrated landscape of inflammatory bowel diseases (IBD) across multiple time points and omics profiles.BACKGROUND Reversible cerebral vasoconstriction syndrome (RCVS) is a rare neurological disorder with a complex physiopathology that is not fully understood. Suggested underlying mechanisms include failure of autoregulation, endothelial dysfunction, and oxidative stress. It is characterized by reversible multifocal constriction of the cerebral arteries, and can be triggered by many conditions, including, vasoactive medications (eg, triptans), cerebrovascular events, primary headache disorders, and metabolic causes (eg, hypercalcemia). RCVS can also be associated with pregnancy-related conditions, such as thrombotic thrombocytopenic purpura, eclampsia, and pre-eclampsia. Thunderclap headache is the most common clinical manifestation; however, other symptoms can result from complications of the disease, such as stroke, brain edema, and seizures. Several case reports have been published of an association between RCVS and eclampsia, but to the best of our knowledge, only 3 cases were successfully treated with intravenous milrinone and this is the only patient reported in Saudi Arabia. CASE REPORT We report a case of 25-year-old primigravida woman who presented with acute-onset headache, nausea, elevated blood pressure, and generalized tonic clonic seizure. She was diagnosed as having RCVS secondary to eclampsia based on clinical and radiological features. She was initially started on nimodipine, which is usually the first-line management of RCVS, as well as magnesium sulfate and levetiracetam; however, she only achieved full recovery after starting intravenous milrinone. CONCLUSIONS Milrinone is one of the emerging drugs for treatment of RCVS, and this case report delineates the potential of using the drug, especially in cases refractory to standard therapy.This review discusses the present strategies in lung separation, the various types of double-lumen tubes (DLTs), and the use of bronchial blockers (BBs). Methods of selecting the correct DLT size and the role of videolaryngoscopy in placing a DLT are reviewed. Mechanisms whereby inhaled anesthetics may be protective during one-lung ventilation (OLV) are highlighted. The risk and prevention of fire during thoracic procedures are discussed.

Neuromuscular blockade (NMB) is a critical part of many surgical procedures. Data on practice patterns of NMB agents (NMBAs) and NMB reversal in recent years in the US ambulatory surgical care setting are limited.

This retrospective analysis of US adult outpatients was conducted using the Premier Healthcare Database. We describe anesthesia practice trends in NMB management and assess the association of patient, procedural, and site characteristics with NMB reversal approach using multivariable logistic regression.

Approximately 5.2 million outpatient surgical encounters involving NMB and 4.6 million involving rocuronium or vecuronium between January 2014 and June 2019 were included. Following the introduction of sugammadex to US clinical practice (~2016), there was an increased use of rocuronium or vecuronium and a decrease in succinylcholine alone. Before 2016, NMB was pharmacologically reversed with neostigmine in approximately two-thirds of outpatient encounters. Over time, active reversal increased;the introduction of sugammadex, although there remains significant practice variability. The multifactorial relationship between patient-, procedural-, and environmental-level characteristics and NMB management is rapidly evolving. Additional research on how these anesthesia practice patterns may be impacted by the shift to the ambulatory care setting and how they may impact patient outcomes and health disparities is warranted.Cataract surgeries are among the most common procedures requiring anesthesia care. Cataracts are a common cause of blindness. Surgery remains the only effective treatment of cataracts. Patients are often elderly with comorbidities. Most cataracts can be treated using topical or regional anesthesia with minimum or no sedation. There is minimal risk of adverse outcomes. Selleckchem MEK inhibitor There is general consensus that cataract surgery is extremely low risk, and the benefits of sight restoration and preservation are enormous. We present the Society for Ambulatory Anesthesia (SAMBA) position statement for preoperative care for cataract surgery.With migration of medically complex patients undergoing more extensive surgical procedures to the ambulatory setting, selecting the appropriate patient is vital. Patient selection can impact patient safety, efficiency, and reportable outcomes at ambulatory surgery centers (ASCs). Identifying suitability for ambulatory surgery is a dynamic process that depends on a complex interplay between the surgical procedure, patient characteristics, and the expected anesthetic technique (eg, sedation/analgesia, local/regional anesthesia, or general anesthesia). In addition, the type of ambulatory setting (ie, short-stay facilities, hospital-based ambulatory center, freestanding ambulatory center, and office-based surgery) and social factors, such as availability of a responsible individual to take care of the patient at home, can also influence patient selection. The purpose of this review is to present current best evidence that would provide guidance to the ambulatory anesthesiologist in making an informed decision regarding patient selection for surgical procedures in freestanding ambulatory facilities.

We describe the implementation of enhanced recovery after surgery (ERAS) programs designed to minimize postoperative nausea and vomiting (PONV) and pain and reduce opioid use in patients undergoing selected procedures at an ambulatory cancer surgery center. Key components of the ERAS included preoperative patient education regarding the postoperative course, liberal preoperative hydration, standardized PONV prophylaxis, appropriate intraoperative fluid management, and multimodal analgesia at all stages.

We retrospectively reviewed data on patients who underwent mastectomy with or without immediate reconstruction, minimally invasive hysterectomy, thyroidectomy, or minimally invasive prostatectomy from the opening of our institution on January 2016 to December 2018. Data collected included use of total intravenous anesthesia (TIVA), rate of PONV rescue, time to first oral opioid, and total intraoperative and postoperative opioid consumption. Compliance with ERAS elements was determined for each service. Quaect progressive improvement achieved through continuous feedback and education of staff.

Total knee replacement (TKR) and total hip replacement (THR) are 2 of the most common orthopedic surgical procedures in the United States. These procedures, with fairly low mortality rates, incur significant health care costs, with almost 40% of the costs associated with post acute care. We assessed the impact of general versus neuraxial anesthesia on discharge destination and 30-day readmissions in patients who underwent total knee and hip replacement in our health system.

This was a retrospective cohort study of 24,684 patients undergoing total knee or hip replacement in 13 hospitals of a large health care network. Following propensity score matching, we studied the impact of type of anesthetic technique on discharge destination (primary outcome) and postoperative complications including readmissions in 8613 patients who underwent THR and 13,004 patients for TKR.

Our results showed that in patients undergoing THR and TKR, neuraxial anesthesia is associated with higher odds of being discharged from hospital to home versus other facilities compared to general anesthesia (odds ratio [OR] = 1.63, 95% confidence interval [CI], 1.52-1.76; P < .01) and (OR = 1.58, 95% CI, 1.49-1.67; P < .01), respectively.

Our results suggest an association between use of neuraxial anesthesia for total joint arthroplasty and a higher probability of discharge to home and a reduction in readmissions.

Patients with body mass index (BMI) ≥50 kg/m2, defined as super morbid obesity, represent the fastest growing segment of patients with obesity in the United States. It is currently unknown if super morbid obese patients are at greater odds than morbid obese patients for poor outcomes after outpatient surgery. The main objective of the current investigation is to assess if super morbid obese patients are at increased odds for postoperative complications after outpatient surgery when compared to morbid obese patients.

The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database from 2017 to 2018 was queried to extract and compare patients who underwent outpatient surgery and were defined as either morbidly obese (BMI >40 and <50 kg/m2) or super morbidly obese (BMI ≥50 kg/m2). The primary outcome was the occurrence of medical adverse events within 72 hours of discharge. In addition, we also examine death and readmissions as secondary outcomes. A propensity-matchedcations (OR [95% CI] = 1.00 [0.98-1.04], P = .87), overall surgical complication (OR [95% CI] = 1.02 [0.98-1.06], P = .23), or readmissions (OR [95% CI] = 0.99 [0.97-1.02], P = .8).

Super morbid obesity is not associated with higher rates of early postoperative complications when compared to morbid obese patients. Specifically, early pulmonary complications were very low after outpatient surgery. Super morbid obese patients should not be excluded from outpatient procedures based on a BMI cutoff alone.

Randomized studies have validated laparoscopic proctectomy for the treatment of rectal cancer as noninferior to an open proctectomy, but most of those studies have included sphincter-preserving resections along with abdominoperineal resection.

This study aimed to compare perioperative and long-term oncological outcomes between minimally invasive and open abdominoperineal resection.

This study is a retrospective analysis of a prospectively maintained database.

The study was conducted in a single specialized colorectal surgery department.

All patients who underwent abdominoperineal resection for primary rectal cancer between 2000 and 2016 were included.

The primary outcomes measured were the perioperative and long-term oncological outcomes.

We included 452 patients, 372 in the open group and 80 in the minimally invasive group, with a median follow-up time of 74 months. There were significant differences between the groups in terms of neoadjuvant radiation treatment (67.5% of the open versus 81.3% of the minimally invasive group, p = 0.
