This study aimed to investigate the prognosis value of 18F-fluorodeoxyglucose PET/computed tomography (18F-FDG PET/CT) in advanced lung cancer patients with immunotherapy combined with chemotherapy.

Fifty-one advanced lung cancer patients were included in this retrospective study, who underwent 18F-FDG PET/CT imaging before four cycles of immunotherapy combined with chemotherapy at our institution between January 2018 and January 2020. The following PET/CT parameters were calculated standardized uptake value SUVmax, SUVmean, SUVpeak, SUVsd, metabolic tumor volume (MTV), total lesion glycolysis (TLG), MTV25%, MTV42%, MTV50%, MTV75%, global lung glycolysis (GLG), target-to-background ratio (TBR), SUVpeakwb, MTVwb, TLGwb, SUVmeanwb, SUVmaxwb. Logistics regression analyses were used for assessing the association between baseline metabolic parameters and response to treatment. Kaplan-Meier estimator curves and the log-rank test were constructed for survival analyses.

According to RECIST, nine patients (18%) advanced lung cancer. Moreover, the combination of SUVmax and histology may predict treatment response with acceptable reliability. However, a large prospective multicenter trial is still needed to examine the above finding for lacking limited evidence.
Endoscopic decompression is considered a first-line treatment for symptomatic pancreatic fluid collections (PFCs). A lumen-apposing metal stent (LAMS) with an electrocautery-enhanced delivery system [electrocautery-enhanced lumen-apposing metal stent (ELAMS)] may facilitate this procedure. This study evaluated the safety and efficacy of ELAMS in the management of symptomatic PFCs.

A multicenter, nonblinded, prospective, Food and Drug Administration (FDA)-approved, investigational device exemption clinical trial was conducted. Enrollment criteria included symptomatic PFCs ≥6 cm with ≥70% fluid fraction. Subjects were followed prospectively for safety, efficacy, and resolution of the collections. Primary endpoint success was defined as ≥50% reduction in PFC size. Clinical outcomes were compared with our previously published series of LAMS without the cautery-enhanced delivery system.

The target enrollment of 30 patients was achieved in 7 US tertiary care centers. All patients underwent successful placement of the ELAMS. The mean procedure duration, stent placement time, and fluoroscopy exposures were 28.1±12.5, 5.8±2.6, and 1.8±1.6 minutes, respectively. Eight patients had no fluoroscopy. The primary endpoint was achieved in 83.3% of patients. Two adverse events were attributed to the ELAMS 1 bleeding upon stent removal and 1 stent migration. Relative to the comparator noncautery LAMS multicenter trial (N=33, 8 tertiary centers), there was a significantly shorter procedure duration [36 min (P<0.001)] with similar technical and clinical outcomes in the ELAMS cohort.

LAMS placed using an electrocautery delivery system significantly reduce procedure duration and were safe and effective in the management of symptomatic PFCs.

The therapeutic efficacy of metal stents (MSs) for pancreatic fluid collections (PFCs) is invariably controversial. Here, we conducted a meta-analysis to summarize the results of efficacy of MSs and plastic stents (PSs) in PFC drainage.

We performed a literature search of PubMed/MEDLINE, EMBASE, and COCHRANE for all of the published studies regarding the use of MSs and PSs for endoscopic transmural drainage of PFCs from January, 1 2015 to June 1, 2020. We extracted data from 9 studies (1359 patients) that met the inclusion criteria. The main outcome measures were the rates of treatment success, including technique success and clinical success (CS), adverse events, recurrence, procedure time, and length of hospital stay (LOS).

There was no difference in overall technique success between patients treated with MSs and PSs for PFCs. However, MSs showed a higher CS rate 92% versus 82% (P<0.01) and a lower overall adverse event rate 20% versus 31% (P<0.01) than PSs. The recurrence rate of PFCs using MSs also had significant advantages over PSs 3% versus 10% (P<0.01) and MSs needed a shorter procedure time than PSs (26.73 vs. 45.40 min, P<0.01). In comparing direct endoscopic necrosectomy use and LOS, there was no difference between MSs and PSs.

Bringing together the results of the current study, endoscopic ultrasound-guided drainage of PFCs using MSs may be superior to PSs in terms of CS, adverse events rates and recurrence rate, with similar LOS and direct endoscopic necrosectomy use.

Although lower extremity muscle strength, joint motion and functional foot alignment are commonly used, time-efficient clinical measures that have been proposed as risk factors for running related injuries (RRIs), it is unclear if these factors can distinguish injury-resistance in runners.

This study compares clinical measures, with consideration of sex, between recently injured runners (3 months to 1 year prior), those with a high level of injury resistance who have been uninjured for at least 2 years, and never-injured runners.

Averaged bilateral values and between-limb symmetry angles of lower limb isometric muscle strength, joint motion, navicular drop and Foot Posture Index (FPI) were assessed in a cohort of recreational runners and their injury history was recorded. Differences in clinical measures between injury groupings were examined, with consideration of sex.

Of the 223 runners tested, 116 had been recently injured, 61 had been injured >2 years ago and were deemed to have acquired re-injifying future injury resistance of runners.
Despite the wide prevalence of gastro-esophageal reflux disease (GERD), the neurophysiological mechanisms underlying heartburn perception in the esophagus of patients with GERD remains incompletely understood. Recent studies have highlighted the potential influence sensory afferent nerves innervating the oesophageal epithelium may have on heartburn pathogenesis. The purpose of this review is to consider the current understanding of esophageal afferent neuronal innervation, including the nociceptive role of acid-sensing receptors expressed on these sensory nerves, in relation to pain perception in the esophagus of GERD patients.

Central and peripheral pathways of sensitization following noxious stimulation of nociceptive receptors expressed on afferent nerves can regulate the strength of sensory nerve activation in the esophagus, which can result in the amplification or suppression of afferent signal transmission. The localization and characterization of mucosal sensory afferent nerves vary between GERD phenotypes and may explain the heterogeneity of symptom perception in patients with apparently similar levels of reflux.

In this review, we discuss the relevance of afferent esophageal innervation in heartburn perception, with a particular focus on the pathways of reflux-induced activation of nociceptive nerves.

Multiple new medications with novel mechanisms of action are now available to treat Crohn's disease (CD). However, they have varying effectiveness in the management of perianal CD. Identifying the most appropriate therapy and optimizing it is essential to maximize effectiveness of therapy. Additionally, the management of perianal CD requires imaging of the perianal area to identify the fistula anatomy and local complications such as abscesses that require surgical drainage. Initial surgical assessment is key to drain abscesses and allow fistula healing with medical therapy.

Although anti-tumor necrosis factor (TNFs) remain the most effective medications to treat perianal CD, real-world data suggests that ustekinumab may be a 2nd-line option in patients nonresponsive to an anti-TNF or having contraindications. Mesenchymal stem cells are an emerging therapeutic approach that is currently in Phase 3 trials in the United States and poised to play a major role in the treatment algorithm.

The management of perianal CD requires a multidisciplinary approach with a combination of initial imaging and surgical assessment to adequately control local sepsis, optimization of biological therapy with adjunct antibiotics or immunomodulators, and close clinical follow-up with imaging to evaluate response to therapy and guide further surgical management options.

Previous studies found that septic patients with normothermia have higher mortality than patients with fever. We hypothesize that antibiotic therapy is less frequently initiated if infectious patients present with normothermia to the emergency department (ED).

To examine the association of body temperature with the initiation of antibiotic therapy in patients attending the ED with suspected and proven infection. Additionally, the association of temperature with 30-day mortality was assessed.

We conducted a retrospective cohort study between 2012 and 2016 at a tertiary university hospital. Adult patients attending the ED with a blood culture taken (i.e. suspected infection) and a positive blood culture (i.e. proven bacteremia) were included.

Tympanic temperature at arrival was categorized as hypothermia (<36.1°C), normothermia (36.1-38.0°C) or hyperthermia (>38.0°C).

Primary outcome was the initiation of antibiotic therapy. A secondary outcome was 30-day mortality. Multivariable logistic regresed with a higher mortality risk than hyperthermia.
Post-transplant lymphoproliferative disorder (PTLD) is a term used to describe a range of lymphoproliferative disorders that occur after solid organ transplant. Although the clinical presentation is variable, primary cutaneous PTLD typically presents as isolated nodules that appear as dermal-based proliferations. BI-3406 clinical trial We present a case of a 70-year-old woman with a history of a kidney transplant who presented with a 2-month history of an asymptomatic, erythematous plaque on the right shin, clinically suspected to be squamous cell carcinoma in situ. Histomorphology demonstrated a dermal proliferation of atypical plasma cells with dense chromatin, variable nucleoli, and irregular nuclear borders. The atypical plasma cells were positive for Epstein-Barr virus by in situ hybridization and markedly kappa-restricted by RNAscope in situ hybridization. A diagnosis of cutaneous monomorphic PTLD, plasma cell neoplasm variant, was rendered, a rare diagnosis in the skin. Treatment for PTLD typically involves reduction of immunosuppression, although our patient progressed and developed new lesions despite this intervention.
