Abstract
We aimed to elucidate the frequency of polymorphic genotypes and alleles of patatin-like phospholipase domain containing 3 rs738409 polymorphism and its possible associations with non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis in a cohort from Turkey.
We enrolled 200 patients diagnosed with NAFLD and genotyped for rs738409 I148M polymorphism by real-time polymerase chain reaction, particularly by melting curve analysis. SPSS analysis software was used for statistical significance. Continuous variable values were expressed as mean ± standard deviation. Significant statistical level was chosen as p
= 0.05.
Our results demonstrate in a cohort from Turkey that rs738409 C > G polymorphism (I148M) of patatin-like phospholipase domain containing 3 gene is significantly able to affect individuals to have NAFLD in unadjusted regression model.
Consistent with the previous studies in other populations, our study group showed a significantly higher risk of having NAFLD in unadjusted regression model but not in the adjusted model indicating that non-genetic factors such as age and sex may be responsible for the association. However, independent studies need to validate our findings with a larger group of NAFLD patients, as well as in different ethnic cohorts.

Published: May 2021

Abstract
Patients with ocular myasthenia gravis (OMG) are frequently treated to prevent the development of generalized myasthenia gravis (GMG). This retrospective cohort study aimed to assess prognostic factors associated with conversion to GMG.
We analyzed the time from the onset of OMG symptoms to GMG in relation to demographic variables, clinical findings, initial investigation results, and treatment regimens using Kaplan–Meier survival curves and multivariate Cox proportional regression analysis.
Of 115 patients diagnosed with OMG (median follow-up time, 2.9 years), 28 (30.4%) developed GMG. The 2-year probability of GMG conversion was 23.7%. Patients with thymic abnormalities and a positive response to repetitive facial nerve stimulation had a significantly higher risk than those with negative results (hazard ratios [HR] 4.28, P < .001 and HR 3.84, P = .04, respectively). Treatment with immunosuppressants was found to be a preventive factor for secondary generalization (HR 0.36, P = .02).
Patients with OMG had a low risk of developing GMG. Immunosuppressive treatments may mitigate disease progression. Chest imaging and repetitive nerve stimulation should be routinely performed to assess the risk of generalization.
Using decision trees to determine participation in bundled payments in sepsis cases
Authors: Matzner William , Freund Deborah 
Published: May 2021

Abstract

Rationale:
The purpose of this research is to determine and develop a valid analytical method that can be easily implemented by providers to evaluate whether they should join the bundled payments for care improvement (BPCI) advanced bundled payment program, and analyze the projected impacts of BPCI advanced payment on their margins.

Methods:
We have developed a decision tree model that incorporates the types of sepsis encountered and the resultant typical complications and associated costs.

Results:
The initial cost of a sepsis episode was $30,386. Since Medicare requires that there is a 3% cost reduction under BPCI, we applied the model with a 3% cost reduction across the board. Since the model considers probabilities of the complications and readmission, there was actually a 3.36% reduction in costs when the 3% reduction was added to the model. We applied 2-way sensitivity analysis to the intensive care unit (ICU) long and short costs. We used the unbundled cost at the high end, and a 10% reduction at the low end. Per patient episode cost varied between $28,117 and $29,658. This is a 5.2% difference between low and high end. Next, we looked at varying the hospital bed (non-ICU) costs. Here the resultant cost varied between $28,708 and $29,099. This is only a 1.34% difference between low and high ends. Finally, we applied a sensitivity analysis varying the attending physician and the intensivist reimbursement fees. The result was a cost that varied between $29,191 and $29,366 which is a difference of only 0.595%.

Conclusion:
This is the precise environment where decision tree analysis modeling is essential. This analysis can guide the hospital in just how to allocate resources in light of the new BPCI advanced payment model.

Abstract
Congenital pyriform sinus fistula (CPSF) is a very rare branchial apparatus malformation. Traditional open surgery for fistulectomy might fail to excise the lesion completely, leading to continual recurrence. Herein, we report our experience of endoscopic coblation technique for treatment of CPSF in children.
To observe the clinical efficacy of endoscopic coblation treatment of CPSF in children, especially for those in acute infection stage.
Retrospective case series with 54 patients (including 20 cases in acute infection stage and 34 cases in non infection stage) who were diagnosed with CPSF between October 2017 to November 2019, all patients were treated with endoscopic coblation to close the piriform fossa fistula, neck abscess incision and drainage performed simultaneously for acute infection stage cases. Data collected including age of diagnosis, presenting symptoms, diagnostic methods, prior and subsequent treatments, length of hospitalization, and recurrence were analyzed.
Of the 20 cases in acute infection stage, there were 3 children with transient vocal cord paresis all of which resolved with 1 month. Four children of the 34 cases in non infection stage appeared reddish swelling of the neck on the 4th, 5th, 6th, and 7th days after coblation and then underwent abscess incision and drainage. All cases experienced no recurrence, vocal cord paralysis, pharyngeal fistula and massive hemorrhage after their first endoscopic coblation of the sinus tract in the follow up of 3 to 28 months.
Endoscopic coblation is an effective and safe approach for children with CPSF, neck abscess incision and drainage could be performed simultaneously in acute infection stage. We advocate using this minimally invasive technique as first line of treatment for CPSF.

Published: May 2021

Abstract
Guidelines for the treatment of rheumatoid arthritis (RA) recommend the use of conventional synthetic disease modifying anti-rheumatic drugs (cs-DMARDs) at the onset of the disease and only in the case of therapeutic failure, the addition of a biological drug (b-DMARD) is suggested.
The study aimed to evaluate determinants for first-line biological treatment in patients with RA in clinical practice.
A cohort of patients with RA, resident in Lazio, a central Italian Region, where Rome is located, and with at least one disease modifying anti-rheumatic drugs (DMARD) prescription between 2010 and 2016 was selected using health information systems linkable with each other by an individual unique anonymous identifier. In particular RA cohort was defined retrieving all patients with at least a RA disease code in regional data claims (hospital discharge, exemption code, emergency department access, or therapeutic plan). Only new users were included and the first-line treatment was identified: cs-DMARD or b-DMARD.
Descriptive analysis according to type of DMARD treatment was performed. Through multivariate logistic regression models (odds ratio [OR]; confidence interval [CI95%]) determinants of therapy such as age, comorbidity, and comedication were investigated.
Finally, switching during the first year of treatment from cs-DAMARDs to b-DMARDs was analyzed.
DMARD-new users with RA were 5641; 7.1% of them with b-DMARD as first-line treatment. Considering the year of dispensing, this percentage ranged from 4.9% (2011) to 8.2% (2015). Among cs-DMARD the most prescribed active agent was methotrexate (59.3%), while among b-DMARD it was etarnecept (37.0%), followed by adalimumab (21.2%). The average age of the cohort was 54 years with 77% of women. Determinants of first-line b-DMARD use were: age (OR<30vs>65 = 3.7; 2.6–5.2, OR[30–45)vs>65 = 1.7; 1.2–2.4, OR[45–55)vs>65 = 1.6; 1.1–2.4, OR[55–65)vs>65 = 1.2; 0.8–1.7), cancers (OR = 2.3; 1.3–4.2), cardio-cerebrovascular disease (OR = 1.4; 1.0–1.9), use of non-steroidal anti-inflammatory drugs (NSAIDs) (OR = 0.6; 0.4–0.7) and corticosteroids (OR = 0.6; 0.5–0.7) in the 6 months preceding diagnosis.
In the first year of treatment, we observed a percentage of switch from cs-DMARDs to b-DMARDs of 7.9%.
In clinical practice, about 7% of patients with RA are prescribed with a b-DMARD as first-line treatment. This therapeutic option, even if not supported by guide lines, is mostly link to younger age and clinical profile of the patients.

Abstract
During outbreaks of the coronavirus disease 2019 (COVID-19), many countries adopted quarantine to slow the spread of the virus of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Quarantine will cause isolation from families, friends, and the public, which consequently leads to serious psychological pressure with potentially long-lasting effects on the quarantined population. Experience of specific practices to improve the psychological status of the mandatory quarantined population was limited. The aim of this study was to investigate the psychological impact of mandatory quarantine, and evaluate the effect of psychological intervention on the quarantined population.
We conducted a prospective cohort study to assess and manage the psychological status of a mandatory quarantined population in Beijing, China. A total of 638 individuals completed 2 questionnaires and were enrolled in this study, of which 372 participants accepted designed psychological intervention while other 266 participants refused it. The SCL-90 questionnaire was used to evaluate the psychological status and its change before and after the intervention. The differences of SCL-90 factor scores between participants and the national norm group were assessed by 2 samples t test. While the SCL-90 factor scores before and after intervention were compared with 2 paired samples t test.
Compared with the Chinese norms of SCL-90, the participants had higher SCL-90 factor scores in most items of the SCL-90 inventory. The SCL-90 factor scores of participants with psychological intervention significantly decreased in somatization, obsessive-compulsive, depression, anxiety, phobic anxiety, paranoid ideation, and psychoticism. In contrast, most factor scores of the SCL-90 inventory changed little without statistical significance in participants without psychological intervention.
Psychological problems should be emphasized in the quarantined individuals and professional psychological intervention was a feasible approach to improve the psychological status of the mandatory quarantined population in the epidemic of SARS-CoV-2.

Abstract

Introduction:
Malignant catatonia (MC) is a movement disorder syndrome characterized by immobility, rigidity, and consciousness disorders that develops in association with mental and physical diseases. It is often fatal due to hyperthermia, rhabdomyolysis, and acute kidney injury. Its clinical symptoms are similar to those of another disorder, neuroleptic malignant syndrome (NMS), and it is often difficult to distinguish between the 2 disorders.

Patient concerns:
An Asian woman in her 60s with history of schizophrenia. She was admitted to our hospital because of symptoms such as fever, unconsciousness, and muscle rigidity. Blood tests showed kidney injury and high creatinine kinase levels.

Diagnoses:
At the time of admission, she had been diagnosed with NMS complicated by pulmonary aspergillosis and was undergoing treatment although there was no improvement.

Interventions:
Subsequently, the administration of propofol, a gamma-aminobutyric acid A agonist, markedly improved the symptoms, and the diagnosis was corrected to MC. At the beginning of her hospitalization, she received dantrolene, bromocriptine, amantadine, and L-3,4-dihydroxyphenylalanine as treatment for NMS, but her symptoms did not improve. With propofol, which is used for sedation, her catatonic symptoms improved markedly. Quetiapine administration further improved the symptoms, and it eventually resolved completely.

Outcomes:
The patient's MC was in remission. Prolonged intensive care management resulted in a decline in activities of daily living, and she required rehabilitation at another hospital.

Conclusion:
This is the first report of MC with suspected involvement of pulmonary aspergillosis. MC differs from NMS, in that it is treated more effectively with gamma-aminobutyric acid A agonists. Although benzodiazepines are the first choice for the diagnosis and treatment of MC, they are ineffective for majority of patients with schizophrenia. However, even in such cases, propofol and quetiapine are effective, and they facilitate diagnosis and treatment.

Published: May 2021

Abstract

Background:
There is a worldwide outbreak of COVID-19, and as the number of patients increases, an increasing number of patients are recovering. However, no relevant systematic review or meta-analysis has been designed to evaluate the effects of acupoint herbal patching on the life of patients recovering from COVID-19.

Methods:
The following electronic databases will be searched from the respective dates of database inception to April 20, 2021: The Cochrane Library, Web of Science, EMBASE, MEDLINE, China National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM), Wanfang database, the Chinese Scientific Journal Database (VIP), and other sources. All published randomized controlled trials in English or Chinese related to acupoint herbal patching for COVID-19 will be included. The primary outcome was the timing of the influence of acupoint herbal patching on the quality of life of convalescent patients. Secondary outcomes were accompanying symptoms (such as myalgia, expectoration, stuffiness, runny nose, pharyngalgia, anhelation, chest distress, dyspnea, crackles, headache, nausea, vomiting, anorexia, diarrhea) disappearance rate, negative COVID-19 results rate on two consecutive occasions (not on the same day), average hospitalization time, clinical curative effect, and improved quality of life.

Results:
The main purpose of this systematic review protocol was to assess the effectiveness and safety of acupoint herbal patching therapy for treating patients recovering from COVID-19.

Conclusion:
The conclusion of our study will provide evidence to judge whether acupoint herbal patching is an effective intervention for the quality of life in patients recovering.

Splicing regulation in hematopoiesis
Authors: Chen Sisi , Abdel-Wahab Omar 
Published: May 2021

Purpose of review
Splicing mutations are among the most recurrent genetic perturbations in hematological malignancies, highlighting an important impact of splicing regulation in hematopoietic development. However, compared to our understanding of splicing factor mutations in hematological malignancies, studies of splicing components and alternative splicing in normal hematopoiesis have been less well investigated. Here, we outline the most recent findings on splicing regulation in normal hematopoiesis and discuss the important questions in the field.

Recent findings
Recent studies have highlighted the critical role of splicing regulation in hematopoiesis, including characterization of splicing components in normal hematopoiesis, investigation of transcriptional alterations on splicing, and identification of stage-specific alternative splicing events during hematopoietic development.

Summary
These interesting findings provide insights on hematopoietic regulation at a co-transcriptional level. More high-throughput RNA ribonucleic acid (RNA) sequencing and functional genomic screens are needed to advance our knowledge of critical alternative splicing patterns in shaping hematopoiesis.
Effects of Botulinum Toxin A on an Incisional Hernia Reconstruction in a Rat Model
Authors: Kwon Jin Geun , Kim Eun Key 
Published: May 2021

Background:
Although the effects of botulinum toxin A on hernia reconstruction have been consistently reported, few studies provide objective evidence. The authors aimed to compare the effects of chemical component separation with those of mechanical component separation, and with a combination of chemical and mechanical component separation, in a rat hernia model.

Methods:
Rats were divided into four groups: 1, control; 2, chemical component separation; 3, mechanical component separation; and 4, chemical and mechanical component separation. Four weeks after hernia induction, botulinum toxin A was injected into groups 2 and 4. Hernia repair was performed 2 weeks after chemical component separation when mechanical component separation was performed in groups 3 and 4. Pretreatment and posttreatment defect sizes, traction forces, intraabdominal pressure, and hernia recurrences were analyzed.

Results:
The defect size was significantly decreased in groups 2 and 4 after chemical component separation. The traction force was significantly smaller in groups 2 and 3 compared with the control group, and the effects of chemical and mechanical component separation were additive. The mean intraabdominal pressure was 16.83 mmHg in group 1, 10.67 mmHg in group 2, 10.17 mmHg in group 3, and 9.67 mmHg in group 4, thus showing significant reductions following chemical and mechanical component separation. Recurrence was observed in all six animals (100 percent) in groups 1 and 3, but in only one of six (17 percent) in groups 2 and 4.

Conclusions:
Preoperative botulinum toxin A significantly reduces hernia size (by 30 percent) and the traction force required to medialize the rectus abdominis. After hernia repair, chemical component separation decreases the intraabdominal pressure to a similar degree as mechanical component separation, but only chemical component separation appears to reduce hernia recurrence.
The Unilateral Cleft Lip Nasal Deformity: Revisions within 20 Years after Primary Correction
Authors: Yao Caroline A. , Mulliken John B. 
Published: May 2021

Background:
As patients grow older, the unilateral cleft lip nasal deformity becomes more noticeable than the repaired lip. The authors assessed nasal revisions over 20 years of the senior author’s management of unilateral complete cleft lip.

Methods:
One hundred patients who underwent primary two-stage nasolabial correction of unilateral complete cleft lip between 1991 and 2001 were reviewed.

Results:
The median patient age was 21 years at the time of analysis. Only 13 percent of patients did not require nasal revision after primary nasolabial repair. One to two nasal revisions were undertaken in 65 percent of patients. The extent of nasal maneuvers during primary labial repair was associated with the number of revisions. Recently treated patients had fewer revisions. Female patients were more likely to undergo several revisions. Of patients who had semiopen suspension sutures at primary repair, 61 percent had this maneuver repeated two or more times. In contrast, patients who had closed suspension sutures at primary repair underwent more nasal revisions and later required more nasal maneuvers. Nasal revision before skeletal maturity was significantly associated with another nasal revision after completion of skeletal growth. Twenty-seven percent of patients eventually required an aesthetic or functional rhinoplasty in adulthood.

Conclusions:
Patients with a severe initial nasal deformity require multiple revisions. Semiopen suspension sutures are associated with fewer revisions. Revision of the nasal cartilages or alar base can often be performed in the intermediate phase, in combination with other operations.

Published: May 2021

Background:
Implant-based reconstruction is the most performed breast reconstruction, and both subpectoral and prepectoral approaches can lead to excellent results. Choosing the best procedure requires a thorough understanding of every single technique, and proper patient selection is critical to achieve surgical success, in particular when dealing with prepectoral breast reconstruction.

Methods:
Between January of 2014 and December of 2018, patients undergoing mastectomy and eligible for immediate prepectoral breast reconstruction with tissue expander or definitive implant, were selected. The Prepectoral Breast Reconstruction Assessment score was applied to evaluate patient-related preoperative and intraoperative risk factors that could influence the success of prepectoral breast reconstruction. All patients were scored retrospectively, and the results obtained through this assessment tool were compared to the records of the surgical procedures actually performed.

Results:
Three hundred fifty-two patients were included; 112 of them underwent direct-to-implant immediate reconstruction, and 240 underwent the two-stage procedure with temporary tissue expander. According to the Prepectoral Breast Reconstruction Assessment score, direct-to-implant reconstruction should have been performed 6.2 percent times less, leading to an increase of 1.4 percent in two-stage reconstruction and 4.8 percent in submuscular implant placement.

Conclusions:
To date, there is no validated system to guide surgeons in identifying the ideal patient for subcutaneous or retropectoral breast reconstruction and eventually whether she is a good candidate for direct-to-implant or two-stage reconstruction. The authors processed a simple risk-assessment score to objectively evaluate the patient’s risk factors, to standardize the decision-making process, and to identify the safest and most reliable breast reconstructive procedure.
