Frequent vascular access thrombosis in a patient with end stage kidney disease on hemodialysis.

Vascular access thrombosis (VAT) is common among patients receiving hemodialysis and leads to missed dialysis treatments, hospitalizations, catheter placement, and graft/fistula abandonment. This article reviews the association between hypercoagulability and VAT and the high prevalence of hypercoagulable states in end-stage kidney disease (ESKD). This article reviews the role of antithrombotic and anticoagulant medications in preventing VAT. The article concludes by reviewing the unique challenges of using vitamin K antagonists in patients with ESKD.

A meta-analysis of laparoscopic versus ultrasound-guided transversus abdominis plane block in laparoscopic colorectal surgery.

BACKGROUND: Enhanced recovery programmes in laparoscopic colorectal surgery (LCS) employ combined approaches to achieve postoperative analgesia. Transversus abdominis plane (TAP) block is a locoregional anaesthetic technique that may reduce postoperative pain. AIMS: To perform a systematic review and meta-analysis to compare the effectiveness of laparoscopic- versus ultrasound-guided TAP block in LCS. METHODS: Databases were searched for relevant articles from inception until March 2022. All randomised controlled trials (RCTs) that compared laparoscopic (LTB) versus ultrasound-guided (UTB) TAP blocks in LCS were included. The primary outcome was narcotic consumption at 24 h postoperatively, whilst secondary outcomes included pain scores at 24 h postoperatively, operative time, postoperative nausea and vomiting (PONV) and complication rates. Random effects models were used to calculate pooled effect size estimates. RESULTS: Three RCTs were included capturing 219 patients. Studies were clinically heterogenous. On random effects analysis, LTB was associated with significantly lower narcotic consumption (SMD - 0.30 mg, 95% CI = - 0.57 to - 0.03, p = 0.03) and pain scores (SMD - 0.29, 95% CI = - 0.56 to - 0.03, p = 0.03) at 24 h. However, there were no differences in operative time (SMD - 0.09 min, 95% CI = - 0.40 to 0.22, p = 0.56), PONV (OR = 0.97, 95% CI = 0.36 to 2.65, p = 0.96) or complication (OR = 1.30, 95% CI = 0.64 to 2.64, p = 0.47) rates. CONCLUSIONS: LTB is associated with significantly less narcotic usage and pain at 24 h postoperatively but similar PONV, operative time and complication rates, compared to UTB. However, the data were inconsistent, and our findings require further investigation. LTB obviates the need for ultrasound devices whilst also decreasing procedure logistical complexity.

Prevalence of Gastrointestinal Symptoms and Irritable Bowel Syndrome Among Individuals With Symptomatic Posttraumatic Stress Disorder.

GOALS: Our aim was to describe the prevalence of irritable bowel syndrome (IBS) and other gastrointestinal symptoms in a sample of veterans with posttraumatic stress disorder (PTSD) and to examine the relationship between gastrointestinal symptoms, PTSD severity, depression severity, and number of prior traumatic events reported. BACKGROUND: IBS and PTSD can co-occur; yet, little research has focused on describing the gastrointestinal symptoms and prevalence of IBS among veterans with PTSD. MATERIALS AND METHODS: We examined baseline data from a randomized clinical trial of behavioral interventions for veterans with PTSD. Veterans completed questionnaires assessing gastrointestinal symptoms (Gastrointestinal Patient-Reported Outcome Measures Information Systems; PROMIS) and lifetime traumatic events. Multivariable regression analyses were performed to examine associations between gastrointestinal symptoms and the number of prior traumas reported PTSD severity, and depression symptom severity. RESULTS: One hundred eighty-four veterans with a diagnosis of PTSD were included. Twenty-five percent met the Rome III criteria for IBS. Veterans reported gastrointestinal symptoms including abdominal/belly pain (36%), diarrhea (21%), constipation (18%), and bloating/gas (17%). In multivariable analyses, greater PTSD severity was associated with worse constipation ( P =0.008), diarrhea ( P =0.005), and gas/bloating ( P =0.001) when controlling for age and sex. Higher levels of depressive symptoms severity were associated with greater abdominal/belly pain ( P =0.04). CONCLUSIONS: Among a sample of veterans with PTSD, rates of IBS and abdominal/belly pain are greater than general US population reference values. Although levels of constipation and bloating/gas are lower than general US population reference values, increased severity of PTSD was associated with increased gastrointestinal symptoms.

Integrative Volume Status Assessment.

Volume status assessment is a critical but challenging clinical skill and is especially important for the management of patients in the emergency department, intensive care unit, and dialysis unit where accurate intravascular assessment is necessary to guide appropriate fluid management. Assessment of volume status is subjective and can vary from provider to provider, posing clinical dilemmas. Traditional non-invasive methods of volume assessment include assessment of skin turgor, axillary sweat, peripheral edema, pulmonary crackles, orthostatic vital signs, and jugular venous distension. Invasive assessments of volume status include direct measurement of central venous pressure and pulmonary artery pressures. Each of these has their own limitations, challenges, and pitfalls and were often validated based on small cohorts with questionable comparators. In the past 30 years, the increased availability, progressive miniaturization, and falling price of ultrasound devices has made point of care ultrasound (POCUS) widely available. Emerging evidence base and increased uptake across multiple subspecialities has facilitated the adoption of this technology. POCUS is now widely available, relatively inexpensive, free of ionizing radiation, and can help providers make medical decisions with more precision. POCUS is not intended to replace the physical exam, but rather to complement clinical assessment, guiding providers to give thorough and accurate clinical care to their patients. We should be mindful of the nascent literature supporting the use of POCUS and other limitations as uptake increases among providers and be wary not to use POCUS to substitute clinical judgement, but integrate ultrasonographic findings carefully with history and clinical examination.

Anastomotic Leak after Ileal Pouch-Anal Anastomosis.

There are special considerations when treating anastomotic leak after restorative proctocolectomy and ileal pouch-anal anastomosis. The epidemiology, risk factors, anatomic considerations, diagnosis and management, as well as the short- and long-term consequences to the patient are unique to this patent population. Additionally, there are specific concerns such as "tip of the J" leaks, transanal management of anastomotic leak/presacral sinus, functional outcomes after leak, and considerations of redo pouch procedures.

Loving-Kindness Meditation vs Cognitive Processing Therapy for Posttraumatic Stress Disorder Among Veterans: A Randomized Clinical Trial.

Importance: Additional options are needed for treatment of posttraumatic stress disorder (PTSD) among veterans. Objective: To determine whether group loving-kindness meditation is noninferior to group cognitive processing therapy for treatment of PTSD. Design, Setting, and Participants: This randomized clinical noninferiority trial assessed PTSD and depression at baseline, posttreatment, and 3- and 6-month follow-up. Veterans were recruited from September 24, 2014, to February 5, 2018, from a large Veternas Affairs medical center in Seattle, Washington. A total of 184 veteran volunteers who met Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) criteria for PTSD were randomized. Data collection was completed November 28, 2018, and data analyses were conducted from December 10, 2018, to November 5, 2019. Interventions: Each intervention comprised 12 weekly 90-minute group sessions. Loving-kindness meditation (n = 91) involves silent repetition of phrases intended to elicit feelings of kindness for oneself and others. Cognitive processing therapy (n = 93) combines cognitive restructuring with emotional processing of trauma-related content. Main Outcomes and Measures: Co-primary outcomes were change in PTSD and depression scores over 6-month follow-up, assessed by the Clinician-Administered PTSD Scale (CAPS-5; range, 0-80; higher is worse) and Patient-Reported Outcome Measurement Information System (PROMIS; reported as standardized T-score with mean [SD] of 50 [10] points; higher is worse) depression measures. Noninferiority margins were 5 points on the CAPS-5 and 4 points on the PROMIS depression measure. Results: Among the 184 veterans (mean [SD] age, 57.1 [13.1] years; 153 men [83.2%]; 107 White participants [58.2%]) included in the study, 91 (49.5%) were randomized to the loving-kindness group, and 93 (50.5%) were randomized to the cognitive processing group. The mean (SD) baseline CAPS-5 score was 35.5 (11.8) and mean (SD) PROMIS depression score was 60.9 (7.9). A total of 121 veterans (66%) completed 6-month follow-up. At 6 months posttreatment, mean CAPS-5 scores were 28.02 (95% CI, 24.72-31.32) for cognitive processing therapy and 25.92 (95% CI, 22.62-29.23) for loving-kindness meditation (difference, 2.09; 95% CI, -2.59 to 6.78), and mean PROMIS depression scores were 61.22 (95% CI, 59.21-63.23) for cognitive processing therapy and 58.88 (95% CI, 56.86-60.91) for loving-kindness meditation (difference, 2.34; 95% CI, -0.52 to 5.19). In superiority analyses, there were no significant between-group differences in CAPS-5 scores, whereas for PROMIS depression scores, greater reductions were found for loving-kindness meditation vs cognitive processing therapy (for patients attending ≥6 visits, ≥4-point improvement was noted in 24 [39.3%] veterans receiving loving-kindness meditation vs 9 (18.0%) receiving cognitive processing therapy; P = .03). Conclusions and Relevance: Among veterans with PTSD, loving-kindness meditation resulted in reductions in PTSD symptoms that were noninferior to group cognitive processing therapy. For both interventions, the magnitude of improvement in PTSD symptoms was modest. Change over time in depressive symptoms was greater for loving-kindness meditation than for cognitive processing therapy. Trial Registration: Clinicaltrials.gov Identifier: NCT01962714.

Impact of the COVID-19 pandemic on management and outcomes in acute appendicitis: Should these new practices be the norm?

BACKGROUND: In early 2020, the COVID-19 pandemic significantly altered management of surgical patients globally. International guidelines recommended that non-operative management be implemented wherever possible (e.g. in proven uncomplicated appendicitis) to reduce pressure on healthcare services and reduce risk of peri-operative viral transmission. We sought to compare our management and outcomes of appendicitis during lockdown vs a non-pandemic period. METHODS: All presentations to our department with a clinical diagnosis of acute appendicitis between 12/03/2020 and 30/06/2020 were compared to the same 110-day period in 2019. Quantity and severity of presentations, use of radiological investigations, rate of operative intervention and histopathological findings were variables collected for comparison. RESULTS: There was a reduction in appendicitis presentations (from 74 to 56 cases), and an increase in radiological imaging (from 70.27% to 89.29%) (P = 0.007) from 2019 to 2020. In 2019, 93.24% of patients had appendicectomy, compared to 71.42% in 2020(P < 0.001). This decrease was most pronounced in uncomplicated cases, whose operative rates dropped from 90.32% to 62.5% (P = 0.009). Post-operative histology confirmed appendicitis in 73.9% in 2019, compared to 97.5% in 2020 (P = 0.001). Normal appendiceal pathology was reported for 17 cases (24.64%) in 2019, compared to none in 2020 (P < 0.001) - a 0% negative appendicectomy rate (NAR). DISCUSSION: The 0% NAR in 2020 is due to a combination of increased CT imaging, a higher threshold to operate, and is impacted by increased disease severity due to delayed patient presentation. This study adds to growing literature promoting routine use of radiological imaging to confirm appendicitis diagnosis. As we enter a second lockdown, patients should be encouraged to avoid late presentations, and surgical departments should continue using radiological imaging more liberally in guiding appendicitis management.

Efficacy and acceptability of mindfulness-based interventions for military veterans: A systematic review and meta-analysis.

BACKGROUND: Military veterans report high rates of psychiatric and physical health symptoms that may be amenable to mindfulness-based interventions (MBIs). Inconsistent prior findings and questions of fit between MBIs and military culture highlight the need for a systematic evaluation of this literature. OBJECTIVE: To quantify the efficacy and acceptability of MBIs for military veterans. DATA SOURCES: We searched five databases (MEDLINE/PubMed, CINAHL, Scopus, Web of Science, PsycINFO) from inception to October 16th, 2019. STUDY SELECTION: Randomized controlled trials (RCTs) testing MBIs in military veterans. RESULTS: Twenty studies (k = 16 unique comparisons, N = 898) were included. At post-treatment, MBIs were superior to non-specific controls (e.g., waitlist, attentional placebos) on measures of posttraumatic stress disorder (PTSD), depression, general psychological symptoms (i.e., aggregated across symptom domains), quality of life / functioning, and mindfulness (Hedges' gs = 0.32 to 0.80), but not physical health. At follow-up (mean length = 3.19 months), MBIs continued to outperform non-specific controls on general psychological symptoms, but not PTSD. MBIs were superior to specific active controls (i.e., other therapies) at post-treatment on measures of PTSD and general psychological symptoms (gs = 0.19 to 0.25). Participants randomized to MBIs showed higher rates of attrition than those randomized to control interventions (odds ratio = 1.98). Several models were not robust to tests of publication bias. Study quality and risk of bias assessment indicated several areas of concern. CONCLUSIONS: MBIs may improve psychological symptoms and quality of life / functioning in veterans. Questionable acceptability and few high-quality studies support the need for rigorous RCTs, potentially adapted to veterans.

Increasing Incidence of Left-Sided Colorectal Cancer in the Young: Age Is Not the Only Factor.

BACKGROUND: Recent single-institution studies have shown that colorectal cancer (CRC) in patients < 50 is predominantly left-sided. The aims of this study were to 1 compare the incidence of left-sided CRC in patients under and over 50, 2 investigate this trend over time, and 3 examine whether racial differences exist in the anatomical distribution of CRC. METHODS: We used the Nationwide Inpatient Sample to identify all patients with colon or rectal cancer who underwent a resection from 2000 to 2014. Logistic regression models were used to determine the odds of a patient having a left-sided CRC based on age and race. RESULTS: A total of 1,547,589 patients underwent resection, with a mean age of 68.6. Overall, 65.1% of patients < 50 had a left-sided CRC compared with 47.2% of patients ≥ 50 (OR = 2.1; 95% CI 2.0, 2.1). The difference was greater as patients became older with 39.9% of patients > 70 having a left-sided CRC (< 50 vs ≥ 70; OR = 2.8; 95% CI 2.7, 2.9). The incidence of CRC in those under 50 increased over the study period due to an increase in left-sided tumors. The distribution of CRC varied with race, with African-Americans having a lower odds for left-sided CRC (OR = 0.89; 95% CI 0.87, 0.91) and Asians/Pacific Islanders having a higher odds (OR = 1.8; 95% CI 1.7, 1.9). CONCLUSION: In the < 50 age group, the incidence of CRC is increasing, with majority of these tumors left-sided. Tumor location varies with both age and race.

Diffuse large B-cell lymphoma of the rectum in a patient with Crohn's disease.

A 62-year-old man presented to our institute with diarrhoea and dysuria on a background of subtotal colectomy and end ileostomy and biological therapy for Crohn's disease. He was diagnosed with urinary tract infection and acute kidney injury (AKI). Renal ultrasound suggested left hydronephrosis, with renal protocol computed tomography (CT) showing a large pelvic mass. Magnetic resonance imaging (MRI) of the pelvis demonstrated a rectal tumour invading the bladder and compressing both ureters. He underwent cystoscopy, flexible sigmoidoscopy and positron emission tomography-CT and was diagnosed with stage IV non-Hodgkin's diffuse large B-cell lymphoma. He was treated primarily with rituximab, cyclophosphamide, hydroxydaunomycin, oncovin and prednisolone chemotherapy regimen. He had ongoing urosepsis before admission for pelvic exenteration. He underwent cystoprostatectomy, excision of rectal stump and formation of ileal conduit. Histology showed no signs of residual malignancy. One year later, the patient was admitted to the intensive care unit with aspiration pneumonia, urosepsis and AKI. Despite maximal therapy, he developed multiorgan failure and passed away.

Excisional Hemorrhoidectomy: Safe in Patients With Crohn's Disease?

INTRODUCTION: Due to concerns over wound healing, hemorrhoidectomy in patients with Crohn's disease (CD) remains controversial. We sought to ascertain safety and efficacy of excisional hemorrhoidectomy in CD. METHODS: A retrospective review of all adult CD patients undergoing excisional hemorrhoidectomy between January 1, 1995, and January 1, 2019, at 2 IBD referral centers was performed. Data collected included patient demographics, clinical characteristics of CD (anorectal symptoms; prior nonoperative hemorrhoidal therapy; presence of other perianal disease; and activity, duration, and anatomic location of CD), and postoperative complications including bleeding, wound healing, and need for further therapy or surgical intervention after surgery. RESULTS: A total of 36 adult patients with Crohn's disease with symptomatic hemorrhoidal disease were included. The study cohort included 16 males (44%), and median age was 49 (range, 21 to 77) years. Predominant symptoms included pain (n = 16; 44%), prolapse (n = 8; 22%), and bleeding (n = 12; 33%). Sixteen patients (44%) had nonoperative therapy before surgery. Twenty-four patients (67%) had other perianal disease. At the time of hemorrhoidectomy, 9 patients (25%) were exposed to corticosteroids, 8 patients (25%) to immunomodulators, and 9 patients (25%) to biologics. During a median follow-up time of 31.5 (range, 1 to 255) months after hemorrhoidectomy, 4 patients (11%) had complications (1 developed a stricture, 1 developed a perianal abscess/fistula, 1 had a nonhealing wound, and 1 had hemorrhoidal recurrence). CONCLUSION: Our data suggest that excisional hemorrhoidectomy may be performed safely in CD patients who have failed nonoperative hemorrhoidal therapy without concern for de novo perianal disease or need for proctectomy.Hemorrhoidal disease is common in patients with Crohn's disease. This study sought to understand the outcomes of surgically treating hemorrhoids in patients with Crohn's disease.

What can we learn from randomized clinical trials about the construct validity of self-report measures of mindfulness? A meta-analysis.

Because they provide data on responsiveness to experimental manipulation, clinical trials involving mindfulness-based interventions are a source of evidence for the construct validity of self-report measures of mindfulness. Within-group and between-group changes in mindfulness were examined from randomized clinical trials comparing mindfulness interventions to other bona fide treatment comparison conditions or waitlist control conditions. We also examined changes in clinical outcomes and the magnitude of these changes relative to changes in mindfulness. We included 69 published studies representing 55 unique samples (n = 4,743). Self-report mindfulness measures showed relatively larger gains in mindfulness intervention conditions vis-à-vis waitlist comparison conditions at both post-treatment (effect size [ES] = 0.52, 95% CI [0.40, 0.64]) and follow-up (ES = 0.52 [0.20, 0.84]), although the effect at follow-up diminished to non-significance in a trim-and-fill analysis intended to account for publication bias (ES = 0.35 [-0.03, 0.72]). Measures of mindfulness also showed relatively larger gains in mindfulness intervention conditions vis-à-vis bona fide comparison conditions, but only at post-treatment (ES = 0.25 [0.11, 0.38], 0.10 [-0.08, 0.28], at post-treatment and follow-up, respectively). All three conditions (mindfulness, bona fide, waitlist) showed relatively larger improvements on measures of clinical outcomes than measures of mindfulness, with the exception of waitlist conditions for which this effect was no longer significant at follow-up. Taken together, findings provide partial support for the unique responsiveness of mindfulness self-report measures to interventions that include promotion of mindfulness meditation practice.

Mindfulness-based cognitive therapy for the treatment of current depressive symptoms: a meta-analysis.

Mindfulness-based cognitive therapy (MBCT) appears to be a promising intervention for the prevention of relapse in major depressive disorder, but its efficacy in patients with current depressive symptoms is less clear. Randomized clinical trials of MBCT for adult patients with current depressive symptoms were included (k = 13, N = 1046). Comparison conditions were coded based on whether they were intended to be therapeutic (specific active controls) or not (non-specific controls). MBCT was superior to non-specific controls at post-treatment (k = 10, d = 0.71, 95% confidence interval [CI] [0.47, 0.96]), although not at longest follow-up (k = 2, d = 1.47, [-0.71, 3.65], mean follow-up = 5.70 months across all studies with follow-up). MBCT did not differ from other active therapies at post-treatment (k = 6, d = 0.002, [-0.43, 0.44]) and longest follow-up (k = 4, d = 0.26, [-0.24, 0.75]). There was some evidence that studies with higher methodological quality showed smaller effects at post-treatment, but no evidence that effects varied by inclusion criterion. The impact of publication bias appeared minimal. MBCT seems to be efficacious for samples with current depressive symptoms at post-treatment, although a limited number of studies tested the long-term effects of this therapy.

Reduced Symptoms of Post-Traumatic Stress Disorder and Irritable Bowel Syndrome Following Mindfulness-Based Stress Reduction Among Veterans.

Objectives: Post-traumatic stress disorder (PTSD) and irritable bowel syndrome (IBS) are highly comorbid conditions associated with reduced health-related quality of life. Comorbid prevalence is especially high among veterans, ranging from 23% to 51%, but there is limited research on integrative treatments. Design: To improve treatment of comorbid PTSD and IBS, this study examined the impact of mindfulness-based stress reduction (MBSR) on symptom reduction and mindfulness skill building among veterans with this comorbidity. We hypothesized that veterans would report reduced trauma-related, gastrointestinal (GI) symptom-specific anxiety (GSA), and depression symptoms and greater mindfulness skills post-treatment. We also hypothesized that veterans who reported lower trauma-related GSA and depression symptoms, and reported greater mindfulness skills and MBSR session attendance would report lower irritable bowel symptoms post-treatment. Settings/Location: VA (Veterans Administration) Puget Sound Health Care System, Seattle, Washington. Subjects: Participants were 55 veterans with PTSD and IBS. Interventions: Veterans participated in an 8-week open trial of MBSR group. Outcome measures: This study measured the impact of MBSR on PTSD, IBS, GSA, and depression symptoms as well as mindfulness skills. Results: Veterans reported reduced trauma-related, irritable bowel, GSA, and depression symptoms and greater mindfulness skills immediately post-treatment. Trauma-related and depression symptom reduction were maintained 4 months post-treatment, but irritable bowel and GSA symptoms were nonsignificant. Lower baseline GSA predicted lower irritable bowel symptoms immediately post-treatment. At 4 months post-treatment, 77.50% met PTSD criteria and 40.38% met IBS criteria compared with 100% veteran comorbidity pretreatment. Conclusions: MBSR holds promise as a transdiagnostic intervention for individuals with comorbid trauma-related, depression, GSA, and irritable bowel symptoms, with maintenance of trauma-related and depression symptom improvement 4 months post-treatment.

Mindfulness-Based Processes of Healing for Veterans with Post-Traumatic Stress Disorder.

OBJECTIVE: U.S. veterans are at increased risk of developing post-traumatic stress disorder (PTSD). Prior studies suggest a benefit of mindfulness-based stress reduction (MBSR) for PTSD, but the mechanisms through which MBSR reduces PTSD symptoms and improves functional status have received limited empirical inquiry. This study used a qualitative approach to better understand how training in mindfulness affects veterans with PTSD. DESIGN: Qualitative study using semistructured in-depth interviews following participation in an MBSR intervention. SETTING: Outpatient. INTERVENTION: Eight-week MBSR program. OUTCOME MEASURE: Participants' narratives of their experiences from participation in the program. RESULTS: Interviews were completed with 15 veterans. Analyses identified six core aspects of participants' MBSR experience related to PTSD: dealing with the past, staying in the present, acceptance of adversity, breathing through stress, relaxation, and openness to self and others. Participants described specific aspects of a holistic mindfulness experience, which appeared to activate introspection and curiosity about their PTSD symptoms. Veterans with PTSD described a number of pathways by which mindfulness practice may help to ameliorate PTSD. CONCLUSIONS: MBSR holds promise as a nontrauma-focused approach to help veterans with PTSD.

Mindfulness-based interventions for psychiatric disorders: A systematic review and meta-analysis.

Despite widespread scientific and popular interest in mindfulness-based interventions, questions regarding the empirical status of these treatments remain. We sought to examine the efficacy of mindfulness-based interventions for clinical populations on disorder-specific symptoms. To address the question of relative efficacy, we coded the strength of the comparison group into five categories: no treatment, minimal treatment, non-specific active control, specific active control, and evidence-based treatment. A total of 142 non-overlapping samples and 12,005 participants were included. At post-treatment, mindfulness-based interventions were superior to no treatment (d=0.55), minimal treatment (d=0.37), non-specific active controls (d=0.35), and specific active controls (d=0.23). Mindfulness conditions did not differ from evidence-based treatments (d=-0.004). At follow-up, mindfulness-based interventions were superior to no treatment conditions (d=0.50), non-specific active controls (d=0.52), and specific active controls (d=0.29). Mindfulness conditions did not differ from minimal treatment conditions (d=0.38) and evidence-based treatments (d=0.09). Effects on specific disorder subgroups showed the most consistent evidence in support of mindfulness for depression, pain conditions, smoking, and addictive disorders. Results support the notion that mindfulness-based interventions hold promise as evidence-based treatments.
