Endoscopic sleeve gastroplasty: a narrative review on historical evolution, physiology, outcomes, and future standpoints
Authors: Brunaldi Vitor Ottoboni , Neto Manoel Galvao 
Published: March 2022

Abstract
Since its first description in 2013, robust evidence supporting the efficacy and safety of the endoscopic sleeve gastroplasty (ESG) has been on the rise. A large case series and meta-analysis report supported results up to 24 months, while some other studies already described 5-year data. If associated with pharmacotherapy, the ESG may help one to achieve weight loss similar to that of surgical sleeve gastrectomy. Though the results of the ongoing randomized trials on ESG are awaited, currently available data support the clinical use of the ESG, especially for patients who are refusing or unfit for bariatric surgery.

Authors: Händel Alexander , Siebelmann Sebastian , Lüke Jan Niklas , Matthaei Mario , Cursiefen Claus , Bachmann Björn 
Published: March 2022

Purpose:
The purpose of this study was to analyze the influence of patient positioning on intraocular pressure (IOP) after Descemet membrane endothelial keratoplasty (DMEK) in pseudophakic patients treated for Fuchs endothelial corneal dystrophy.

Methods:
Forty patients were included in this prospective, single-blinded, randomized controlled clinical trial. Patients received a YAG iridotomy 1 day before surgery and an 80% anterior chamber tamponade [20% concentration of sulfur hexafluoride (SF6)]. Postoperative positioning was either supine (group 1) or seated (group 2, at least 30 degrees upper-body high position). IOP was measured with iCare.

Results:
There was no statistically significant difference in IOP postoperatively [group 1 vs. group 2—after 1h: 13.9 mm Hg (±4.2 mm Hg) versus 13.6 mm Hg (±4.1 mm Hg) (P = 1.00); after 2h: 13.9 mm Hg (±5.4 mm Hg) versus 15.3 mm Hg (±4.6 mm Hg) (P = 0.370); after 4h: 13.8 mm Hg (±4.2 mm Hg) versus 15.2 mm Hg (±4.2 mm Hg) (P = 0.401]. In group 1, 10% of patients showed IOP decompensations well above 30 mm Hg, and in group 2, there were no IOP decompensations. Seated position led to relative risk reduction of 100% and absolute risk reduction of 10% regarding IOP decompensations. The number of patients needed to position seated to prevent 1 additional IOP decompensation was 10. Rebubbling rates, best spectacle–corrected visual acuity, and reduction of corneal thickness were comparable between the 2 groups in the follow-up period up to 1 month.

Conclusions:
After DMEK in pseudophakic eyes with 80% anterior chamber tamponade, positioning patients with at least 30 degrees elevation of the upper body up immediately after surgery until bedtime prevents IOP decompensations.

Authors: Ariño-Gutierrez Mayte , Moloney Gregory , Burgos-Blasco Barbara , Arriola-Villalobos Pedro , Cuiña-Sardiña Ricardo , Diaz-Valle David 
Published: March 2022

Purpose:
The purpose of this study was to report the clinical outcomes of postoperative repositioning of 2 inverted Descemet membrane endothelial keratoplasty (DMEK) grafts in 2 patients with endothelial dysfunction.

Methods:
Two patients underwent DMEK surgery in a tertiary referral corneal clinic. Initial surgery was performed by 2 different corneal surgeons, and a third surgeon repositioned both cases. In the early postoperative period, partial and subtotal detachments were observed at slitlamp and inverted graft orientation was confirmed by anterior segment optical coherence tomography. In both cases, uneventful reposition of the inverted graft was performed by an experienced DMEK surgeon on days 2 and 9 after initial DMEK surgery.

Results:
Repositioning surgery was successful in both patients. The Moutsouris sign was used to confirm proper orientation. One patient had total graft adherence at day 1 postrepositioning. The second patient required a rebubbling procedure, despite the correct orientation confirmed by using anterior segment optical coherence tomography. Visual acuity and corneal thickness were stable in both cases (case 1: 20/30, 567 μm; case 2: 20/80, 543 μm). Both patients had clear corneas and functional cell counts 2 years after repositioning (451 cells/mm2 and 1052 cells/mm2).

Conclusions:
Postoperative repositioning of an inverted DMEK graft may be a viable procedure to delay or prevent regrafting.
Observational study of the clinical utility of sulfamethoxazole serum level monitoring in the treatment of brain abscesses due to Nocardia species
Authors: Corsini Campioli Cristina , Abu Saleh Omar , Mara Kristin C. , Rivera Christina G. 
Published: March 2022

Abstract
Although there is a lack of data in trimethoprim-sulfamethoxazole (TMP-SMX) serum monitoring utility for invasive nocardial infections, therapeutic drug monitoring is widely used to optimize dosing and avoid adverse reactions that may cause treatment interruption.
We retrospectively reviewed all adults who received TMP-SMX to treat nocardial brain abscess and had SMX serum level testing from 2010 to 2020.
Twenty-two patients received treatment with TMP-SMX for Nocardia species brain abscess and 16 (72.7%) had a reported SMX level, with a median patient age of 65.5 years (interquartile range, IQR 59.5–72.5). Compared to those who did not have a documented SMX serum level, patients with SMX levels had a shorter median course of TMP-SMX treatment (322 days [IQR 188–365] vs. 365 [IQR 224–365]; P = .31) and higher therapeutic induction dose (10 [62.5%] vs. 3 [50%]; P = .92). Similarly, they were more frequently on hemodialysis (3 [13.6%] vs. 1 [4.5%]; P = > .99). The median peak level was 158.5 (IQR 120–218) μg/mL, collected at 2 hours (75%) post-administration in the induction phase (81.3%). Patients with documented SMX levels had fewer reported drug toxicity (5 [31.3%] vs. 4 [66.7%]; P = .1) than those without SMX levels. Among the five patients who reported TMP-SMX-related toxicity, 4 (80%) had an SMX peak level >150 μg/mL. There was no difference in the cure, relapse, and death rates among the two groups.
While SMX level was not associated with Nocardia species brain abscess cure rates and mortality, most patients with SMX peak >150 μg/mL experienced drug toxicity.
Influence of hemoglobin concentration on the in-hospital outcomes in newly diagnosed heart failure patients with atrial fibrillation
Authors: Dong Mengya , Xu Chenbo , Zhou Juan , Yuan Zuyi 
Published: March 2022

Abstract
Atrial fibrillation (AF) and heart failure (HF) coexistence is common of clinical significance. Although anemia is a well-recognized risk factor for adverse outcomes, the prognostic value of hemoglobin is controversial in AF and HF. We aimed to determine whether hemoglobin is associated with in-hospital outcomes in such patients.
On the basis of the data from the CCC-AF (Improving Care for Cardiovascular Diseases in China-Atrial Fibrillation) project, 2367 inpatients with a definitive diagnosis of AF and HF and record of admission hemoglobin concentration were included. Logistic regression analysis was performed to investigate the relationship between hemoglobin and in-hospital outcomes.
All patients were divided into 4 groups according to quartiles of hemoglobin values. Compared with patients with higher hemoglobin, patients with lower hemoglobin had higher proportion of males, heart rate (HR), and diastolic blood pressure (DBP). On the contrary, they had lower age, medical history, left ventricular ejection fraction (LVEF), and brain natriuretic peptide (P < .05). Spearman correlation showed that hemoglobin was negatively correlated with age, LVEF, international normalized ratio, and serum creatinine but positively correlated with HR, DBP, and blood urea nitrogen (P < .05). Multivariable logistic regression analysis revealed that increasing hemoglobin was an independent protective factor for in-hospital outcomes (odds ratio = 0.989; 95% confidence interval: 0.979–1.000; P = .046).
Admission hemoglobin concentration was an independent protective factor for in-hospital outcomes in HF patients with AF. Our study indicated that increasing hemoglobin level and improving anemia degree might improve the prognosis of patients with AF and HF.

Published: March 2022

Abstract
We aimed to determine the clinical outcome of double cleavage-stage embryo transfers in frozen-thawed embryo transfer cycles for older women.
This study analyzed a total of 8189 cleavage-stage frozen-thawed embryo transfer cycles between January 2013 and December 2017 at Sir Run Run Shaw Hospital. All cycles were sorted into 3 groups based on patient age: ≤35 years (Group A), 36 to 37 years (Group B), and ≥38 years (Group C). The clinical pregnancy rate (CPR), implantation rate (IR), live birth rate (LBR), miscarriage rate, multiple pregnancy rate (MPR), preterm birth rate, and low-birth-weight rate were compared between the 3 groups.
Significant differences in CPR, IR, LBR, MPR, and premature birth rate were found among the 3 groups. The CPR, IR, LBR, and MPR in Group A were higher than those in Group C. Transfers of 2 high-quality embryos resulted in significant differences in CPR, IR, LBR, MPR, and neonatal weight among the 3 groups, but no differences in premature birth and abortion rates were observed. Transfers with 1 high-quality and 1 fair-quality embryo resulted in significant differences in CPR, IR, and LBR among the 3 groups. Comparison of transfers of 2 high-quality embryos with 1 high-quality and 1 fair-quality embryo showed that the CPR and LBR were significantly lower for the latter in Groups A and C, but Group B had no salient changes.
Higher IR and LBR and lower MPR may be achieved by selection of optimal embryo types for patients of different ages. Two high-quality embryos need to be transferred in women older than 38 years. For women aged 36 to 37 years, 1 high-quality embryo or 1 high-quality plus 1 fair-quality embryo should be singled out for transfer. For women younger than 35 years, a single high-quality embryo should be selected for transfer.

Abstract

Background:
Obesity—a public health problem that negatively affects the quality of life—is associated with various diseases, and its prevalence is on the rise. Although drugs and surgical interventions are used to treat obesity, they have adverse effects and limitations. Electroacupuncture is a widely used method for treating obesity in which electrical stimulation is transmitted to the body through acupuncture needles. This systematic review and meta-analysis will evaluate the efficacy of electroacupuncture in treating obesity.

Methods:
MEDLINE/PubMed, EMBASE, the Cochrane Central Register of Controlled Trials, 3 Korean databases (Oriental Medicine Advanced Searching Integrated System, ScienceON, and KoreaMed), 1 Japanese database (Citation Information by the National Institute of Informatics), and 1 Chinese database (Chinese National Knowledge Infrastructure) will be searched from their inception to December 2021. The primary outcome will be body mass index, and the secondary outcomes will be body weight, waist and hip circumference, waist-to-hip ratio, body fat percentage, body fat mass, and adverse effects.

Results and conclusion:
This systematic review and meta-analysis will provide evidence for efficacy of electroacupuncture as a treatment method for obesity.

Authors: Wang Ying , Guo Sha , Xiao Meng-Lu , Zhang Hong 
Published: March 2022

Abstract

Background:
Poststroke cognitive impairment (PSCI) is often secondary to poststroke, which is common in stroke patients, induced difficulty in rehabilitation and seriously affects their quality of life. Currently, effective treatments are still limited. Researches show that acupuncture combined with traditional Chinese medicine (TCM) has a good effect on PSCI. However, there is no consistent conclusion at present. Therefore, THE purpose of this study is to assess the effectiveness and safety of acupuncture combined with TCM in the treatment of PSCI.

Methods:
We will search the following databases from inception to January, 2022: the Cochrane Library, PubMed, Embase, Medline, Web of Science, China National Knowledge Infrastructure, China Biology Medicine, Wan Fang data, and the Chinese Science and Technology Periodical Database. All randomized controlled trials eligible for acupuncture combined with TCM for PSCI will be included in this study. Study selection, data extraction, and quality assessment will be performed by 2 reviewers independently. Bias risk assessment and data synthesis will be performed using the Review Manager software (RevMan, version 5.3) and R (version 3.6.1) software.

Results:
We will synthesize the current studies to evaluate the effectiveness and safety of acupuncture combined with TCM in the treatment of PSCI.

Conclusion:
The systematic review will provide a new paradigm for acupuncture combined with TCM in the intervention of PSCI, and further provide scientific evidence for the efficacy and safety of acupuncture combined with TCM in the treatment of PSCI.

Out-of-Network Care in Commercially Insured Pediatric Patients According to Medical Complexity
Authors: Xu Wendy Y. , Li Yiting , Song Chi , Bose-Brill Seuli , Retchin Sheldon M. 
Published: March 2022

Background:
Commercial health plans establish networks and require much higher cost sharing for out-of-network (OON) care. Yet, the adequacy of health plan networks for access to pediatric specialists, especially for children with medical complexity, is largely unknown.

Objective:
To examine differences in OON care and associated cost-sharing payments for commercially insured children with different levels of medical complexity.

Design:
Cross-sectional study using a nationwide commercial claims database.

Subjects:
Enrollees 0–18 years old in employer-sponsored insurance plans. The Pediatric Medical Complexity Algorithm was used to classify individuals into 3 levels of medical complexity: children with no chronic disease, children with non-complex chronic diseases, and children with complex chronic diseases.

Main Outcomes:
OON care rates, cost-sharing payments for OON care and in-network care, OON cost sharing as a proportion of total health care spending, and OON cost sharing as a proportion of total cost sharing.

Results:
The study sample included 6,399,006 individuals with no chronic disease, 1,674,450 with noncomplex chronic diseases, and 603,237 with complex chronic diseases. Children with noncomplex chronic diseases were more likely to encounter OON care by 6.77 percentage points with higher cost-sharing by $288 for OON care, relative to those with no chronic disease. For those with complex chronic diseases, these differences rose to 16.08 percentage points and $599, respectively. Among children who saw behavioral health providers, rates of OON care were especially high.

Conclusions:
Commercially insured children with medical complexity experience higher rates of OON care with higher OON cost-sharing payments compared with those with no chronic disease.
The role of radiotherapy in oligometastatic hormone-sensitive prostate cancer
Authors: Abdel-Aty Hoda , James Nicholas D. 
Published: March 2022

Purpose of review
The aim of this article is to review the role of radiotherapy in the management of oligometastatic hormone-sensitive prostate cancer (HSPC).

Recent findings
The M1|RT STAMPEDE trial showed a survival advantage to prostate radiotherapy in newly diagnosed oligometastatic HSPC. The combination of prostate radiotherapy with systemic treatment is now the recommended standard of care. Metastases-directed therapy (MDT) with stereotactic ablative radiotherapy (SABR) in the STOMP and ORIOLE trial reported excellent local control and a survival advantage in metachronous oligometastatic HSPC. Results were consistent with prostate cancer outcomes in the SABR-COMET trial and the NHS England Commissioning through Evaluation scheme (CtE). SABR in synchronous oligometastatic HSPC will be evaluated in a new comparison within the STAMPEDE trial. Current definition of oligometastatic HSPC is based on the number of metastatic lesions on conventional imaging (CT/MRI and Isotope bone scan). Novel imaging, such as PSMA PET/CT provide superior accuracy to conventional imaging. However, limited data exists on the role of novel imaging in determining subsequent clinical outcomes.

Summary
Prostate radiotherapy improves survival and is standard of care with systemic treatment in newly diagnosed oligometastatic HSPC. The role of SABR in newly diagnosed oligometastatic HSPC is yet to be determined.
Effective Treatment of Chronic Mastectomy Pain with Intercostal Sensory Neurectomy
Authors: Hart Sarah E. , Agarwal Shailesh , Hamill Jennifer B. , Brown David L. 
Published: March 2022

Summary:
Chronic postmastectomy pain affects up to 40 percent of patients and leads to diminished quality of life and increased risk of opioid dependence. The cause of this pain is incompletely understood; however, one hypothesis is that direct injury to cutaneous intercostal nerves at the time of mastectomy and/or reconstruction leads to chronic pain. As a result, proximal neurectomy of the involved sensory nerve(s) has been suggested to be effective for these patients. The purpose of this study was to determine whether chronic pain in postmastectomy patients can be diagnosed reliably in an office setting and pain reduced by intercostal sensory neurectomy. The authors performed a retrospective review of seven patients with a history of breast surgery and chronic pain who underwent intercostal neurectomy combined with muscle or dermal wrapping of the proximal end of the resected nerve. All patients were diagnosed by history and physical examination, and suspected nerves were further identified with local anesthetic nerve blocks. An average of 3.14 neurectomies were performed per patient (range, one to six). There was a significant reduction in visual analogue scale pain scores following surgery, from 9 preoperatively to 1 postoperatively (p = 0.02). Eighty-six percent of patients were pain-free or “considerably improved” at their latest follow-up appointment (average, 6.14 months). It is concluded that intercostal sensory nerve injury at the time of mastectomy and/or reconstruction can lead to chronic mastectomy pain, which can be easily diagnosed and effectively treated with intercostal neurectomy.

Published: March 2022

Purpose:
Object naming requires visual decoding, conceptualization, semantic categorization, and phonological encoding, all within 400 to 600 ms of stimulus presentation and before a word is spoken. In this study, we sought to predict semantic categories of naming responses based on prearticulatory brain activity recorded with scalp EEG in healthy individuals.

Methods:
We assessed 19 healthy individuals who completed a naming task while undergoing EEG. The naming task consisted of 120 drawings of animate/inanimate objects or abstract drawings. We applied a one-dimensional, two-layer, neural network to predict the semantic categories of naming responses based on prearticulatory brain activity.

Results:
Classifications of animate, inanimate, and abstract responses had an average accuracy of 80%, sensitivity of 72%, and specificity of 87% across participants. Across participants, time points with the highest average weights were between 470 and 490 milliseconds after stimulus presentation, and electrodes with the highest weights were located over the left and right frontal brain areas.

Conclusions:
Scalp EEG can be successfully used in predicting naming responses through prearticulatory brain activity. Interparticipant variability in feature weights suggests that individualized models are necessary for highest accuracy. Our findings may inform future applications of EEG in reconstructing speech for individuals with and without speech impairments.

AbstractWe developed a method for altering terrain unevenness on a treadmill to study gait kinematics. Terrain consisted of rigid polyurethane disks (12.7 cm diameter, 1.3-3.8 cm tall) which attached to the treadmill belt using hook-and-loop fasteners. Here, we tested four terrain unevenness conditions: Flat, Low, Medium, and High. The main objective was to test the hypothesis that increasing the unevenness of the terrain would result in greater gait kinematic variability. Seventeen younger adults (age 20-40 years), 25 higher-functioning older adults (age 65+ years), and 29 lower-functioning older adults (age 65+ years, Short Physical Performance Battery score < 10) participated. We customized the treadmill speed to each participant’s walking ability, keeping the speed constant across all four terrain conditions. Participants completed two 3-minute walking trials per condition. Using an inertial measurement unit placed over the sacrum and pressure sensors in the shoes, we calculated the stride-to-stride variability in step duration and sacral excursion (coefficient of variation; standard deviation expressed as percentage of the mean). Participants also self-reported their perceived stability for each condition. Terrain was a significant predictor of step duration variability, which roughly doubled from Flat to High terrain for all participant groups: younger adults (Flat 4.0%, High 8.2%), higher-functioning older adults (Flat 5.0%, High 8.9%), lower-functioning older adults (Flat 7.0%, High 14.1%). Similarly, all groups exhibited significant increases in sacral excursion variability for all three uneven terrain conditions compared to Flat. Participants were also significantly more likely to report feeling less stable walking over all three uneven terrain conditions compared to Flat. These findings support the hypothesis that altering terrain unevenness on a treadmill will increase gait kinematic variability and reduce perceived stability in younger and older adults.
