Abstract
Purpose: To review our experience with pediatric congenital buttock sinus tract, and to conclude the clinical characteristics and management of the disease.
Methods: Twenty-two pediatric patients diagnosed with congenital buttock sinus tract were included. Medical records were reviewed, and the patients were followed up. Continuous variables were presented by median and range. Categorical variables were presented as frequencies and percentages.
Results: Among the 22 patients, there were 8 boys (36.4%) and 14 girls (63.6%). The median first onset age was 42 months, and the range was 5 months to 12 years old. Admission age was 69.5 months, with a range from 14 months to 12 years old. Overall prior treatment time was 11 months, ranging from 3 months to 11 years. Twenty-one patients had definite congenital dimples since birth, and later manifested with infection through the dimple. All patients came to the doctor with complaint of the infection. The number of invasive procedures ranged from 0 to 5, with an average of 2. Radiology could exactly display the morphology and show the termination as a retrorectal cyst. The surgical procedure was adopted trans-fistula tract, and the pathological results showed a dermoid cyst in 11 patients and an epidermoid cyst in 10 patients. During the follow-up period of 34.5 months (range, 2 months to 8 years), 19 patients were uneventful and 3 patients suffered recurrence. Two of them underwent a second operation and had no recurrence ever since. The third patient did not receive a second operation, and the refractory infection was still present.
Conclusions: Pediatric congenital buttock sinus tract is rare and has a female predominance in the morbidity. Patients have a distinctive congenital dimple on the buttock with recurrent infection, and there usually exists a congenital sinus tract from the dimple to the retrorectal space. Total excision is the only method for the cure. The nature of the disease is a retrorectal developing dermoid cyst or epidermoid cyst.

Background: Lung metastasectomy in the treatment of advanced colorectal cancer has been widely adopted without good evidence of survival or palliative benefit. We aimed to test its effectiveness in a randomised trial (RCT).

Methods: Multidisciplinary teams in 13 hospitals recruited participants with potentially resectable lung metastases to a multicentre 2-arm RCT comparing active monitoring with or without metastasectomy. Other local or systemic treatments were decided by the local team. Randomisation was remote and stratified by site with minimisation for age, sex, primary cancer stage, interval since primary resection, prior liver involvement, the number of metastases, and carcinoembryonic antigen. The central trial management group were blind to patient allocation until completion of the analysis. Analysis was on intention to treat with a margin for non-inferiority of 10%.

Results: Between December 2010 and December 2016, 65 participants were randomised. Characteristics were well-matched in the two arms and similar to those in reported studies: age 35 to 86 (Inter Quartile Range (IQR) 60 to 74); primary resection IQR 16 to 35 months previously; stage at resection T1, 2 or 3 in 3, 8 and 46; N1 or N2 in 31 and 26; unknown in 8. Lung metastases 1 to 5 (median 2); 16/65 had previous liver metastases; carcinoembryonic antigen normal in 55/65. There were no other interventions in the first 6 months, no cross overs from control to treatment, and no treatment-related deaths or major adverse events. Hazard ratio for death within 5 years, comparing metastasectomy with control, was 0.82 (95%CI 0.43, 1.56).

Conclusions: Because of poor and worsening recruitment, the study was stopped. The small number of participants in the trial (N=65) precludes a conclusive answer to the research question given the large overlap in the confidence intervals in the proportions still alive at all time points. A widely held belief is that the five-year absolute survival benefit with metastasectomy is about 35%: 40% after metastasectomy compared to <5% in controls. The estimated survival in this study was 38% (23-62%) for metastasectomy patients and 29% (16-52%) in the well-matched controls. That is the new and important finding of this RCT.

Published: November 2019

Abstract
Introduction Alcohol dependence is a common disorder with a continuum regarding severity. Most alcohol dependent persons have a moderate level of dependence and live under socially orderly conditions. Treatment seeking in this group is low, mainly due to stigma and because treatment options are seen as unappealing. Alcohol is a relevant topic to discuss in many primary care (PC) consultations and PC is less stigmatizing to visit compared to addiction care units for people with alcohol problems. General practitioners (GP) hesitate to engage in treating alcohol problems due to time constraints and lack of knowledge. Screening and brief interventions are effective for high consumers but there are few studies on dependence. Methods This is a two-group, parallel, randomized controlled trial (RCT). The aim is to study whether an Internet based Cognitive Behavioral Treatment (iCBT) when added to treatment as usual (TAU) is more effective than TAU only for alcohol dependence in PC. 260 adults with alcohol dependence will be included. Participants are randomized to iCBT and TAU or TAU only. The primary study outcome is alcohol consumption in grams per week and heavy drinking days. Secondary outcomes include alcohol related problem severity, number of diagnostic criteria for alcohol dependence, depression and anxiety symptoms, health related quality of life and biochemical markers for high consumption and liver pathology. Data will be analyzed using mixed-effect models. Discussion Internet based interventions are attractive to and have been shown to reach people with alcohol problems. Yet there are no studies investigating the efficacy of internet treatment of alcohol dependence in PC. In this study we hypothesize that iCBT when added to TAU will improve treatment outcome for alcohol dependence in PC, compared to TAU only. If effective, iCBT can be distributed to the public to a low cost for a stakeholder and has the opportunity to reduce both short term and long-term public health costs.

Published: November 2019

Abstract
Background The aim of this study was to investigate the efficacy and safety of the novel complex drug, consisting of released-active form of antibodies to S-100 protein, tumor necrosis factor-α and histamine, (Kolofort) under outpatient conditions in patients with functional dyspepsia (FD), irritable bowel syndrome (IBS), and their combination. Methods The subject of the observational noninterventional retrospective program was the data of 14,362 outpatient records of patients with diagnosed FD, IBS, and/or their combination who received the drug Kolofort in monotherapy for 12 weeks, 2 tablets twice a day. To assess the presence and severity of symptoms of functional disorders of the gastrointestinal tract (FD GIT), a questionnaire “7*7” developed by a working group from the Russian Gastroenterological Association was used. The evaluated parameters included the proportion of patients: who had a reduction in the number of points by 50% or more; who have decreased the severity category of the condition; who have switched to the “healthy” and “borderline ill” severity categories;and the change in the number of points in domains 1–7. Results The final efficacy analysis included data from 9,254 patients. A decrease in the number of points by 50% or more was observed in 80.45% of patients with FD, 79.02% of patients with IBS, and in 83% of patients with both IBS and FD. A decrease in the severity category of the condition at the end of therapy was noted in 93.35% of patients with FD, in 93.80% of cases in patients with IBS, and in 96.17% of cases in patients with a combination of IBS and FD.A total of 94 adverse events (AEs) were reported in 80 patients (0.65%). Conclusion The COMFORT program has demonstrated the positive effect of treatment in the majority of patients with IBS and FD and their combination in real clinical practice.

Published: November 2019

Abstract
Background. Sepsis is a leading cause of death worldwide and a major challenge for physicians to predict and manage. Proenkephalin A 119-159 (penKid) is a reliable surrogate marker for the more unstable endogenous opioid peptide enkephalin, which has previously been shown to predict both acute and chronic kidney disease. The aim of this prospective observational study was to assess penKid as a predictor of acute kidney injury (AKI), multi-organ failure and mortality in sepsis among unselected sepsis patients presenting to the emergency department (ED). Method. We enrolled 644 patients consecutively during office-hours (6AM-6PM) between December 1, 2013 and February 1, 2015. 56 patients were excluded due to incomplete data. We measured penKid in 588 adult patients (patients under 18 years of age were excluded) with sepsis (≥2SIRS criteria + suspected infection) upon admission to the ED at Skåne University Hospital, Malmö, Sweden. Logistic regression analysis was used to relate levels of penKid at presentation to AKI, multi-organ failure, 28-day mortality and progression of renal SOFA subscore. Odds ratios are presented as the number of standard deviations from the mean of log-transformed penKid. Results. In age and sex adjusted models, penKid predicted AKI within 48 hours and 7 days, but these associations were attenuated after additional adjustment for estimated creatinine-based glomerular filtration rate (eGFR). In models adjusted for age, sex and eGFR, penKid significantly predicted progression from rSOFA=0 and ≤1 to higher rSOFA scores as well as multi-organ failure and mortality. In contrast, eGFR did not predict 28-day mortality. Conclusion. PenKid is an effective predictor of renal injury, severe multi-organ failure and mortality in unselected sepsis patients presenting to the emergency department.

Abstract
Precisely measuring the location and frequency of DNA double-strand breaks \(DSBs) along the genome is instrumental to understanding genomic fragility, but current methods are limited in versatility, sensitivity, or practicality. Here, we present Breaks Labeling _In Situ_ and Sequencing \(BLISS), featuring: 1) direct labeling of DSBs in fixed cells or tissue sections on a solid surface; 2) low-input requirement by linear amplification of tagged DSBs by _in vitro_ transcription; 3) quantification of DSBs through unique molecular identifiers; and 4) easy scalability and multiplexing. We apply BLISS to profile endogenous and exogenous DSBs in low-input samples of cancer cells, embryonic stem cells, and liver tissue. We demonstrate the sensitivity of BLISS by assessing the genome-wide off-target activity of two CRISPR-associated RNA-guided endonucleases, Cas9 and Cpf1, observing that Cpf1 has higher specificity than Cas9. Our results establish BLISS as a versatile, sensitive, and efficient method for genome-wide DSB mapping in many applications.

Abstract
Objectives: The study was carried out to optimize the phenotypic method to characterize the sickle cell trait (SCT), sickle cell anaemia (SCA) and β-thalassemia (β-TT) suspected sample from tharu community of South Western province-5, Nepal. SCT and SCA were further evaluated by genotypic method employing amplification refractory mutation system (ARMS PCR). Moreover, Glucose 6 Phosphate Dehydrogenase (G6PD) was estimated in those hemoglobinopathy to observe its prevalence. The accurate and reliable method can play an important role in reduction of morbidity and mortality rate.
Results: The 100 suspected cases were subjected to phenotypic method adopting cellulose acetate electrophoresis and genotypic metod using ARMS PCR which portraits (5%) SCA positive test showing HBS/HBS, (38%) SCT positive trait HBA/HBS and (36%) cases normal HBA/HBA. β-TT (21%) cases were confirmed by electropherogram. G6PD deficiency was observed in (40%) of SCA, (18.4%) of SCT, (4.8%) of β-TT and (2.8%) in normal cases. Increased G6PD were developed only in SCT (5.3 %) and β-TT (4.8%). The study highlighted sickle cell disorder (SCD) and β-TT as the most common hemoglobinopathy coexisting with G6PD deficiency. Though hemoglobinopathy sometime could be protective in malaria but G6PD deficiency can cause massive hemolysis which may exacerbate the condition.

Published: November 2019

Abstract
Background: Social disparities in healthcare persist in the US despite the expansion of Medicaid under the Affordable Care Act. We investigated the causal impact of socioeconomic status on the quality of care in a setting with minimal confounding bias from race, insurance type, and access to care.
Methods: We designed a retrospective population-based study with a random 25% sample of adult Taiwan population enrolled in Taiwan’s National Health Insurance system from 2000 to 2016. Patient’s income levels were categorized into low-income group (<25th percentile) and high-income group (≥25th percentile). We used marginal structural modeling analysis to calculate the odds of hospital admissions for 11 ambulatory care sensitive conditions identified by the Agency for Healthcare Research and Quality and the odds of having an Elixhauser comorbidity index greater than zero for low-income patients.
Results: Among 2,844,334 patients, those in lower-income group had 1.28 greater odds (95% CI 1.24 – 1.33) of experiencing preventable hospitalizations, and 1.04 greater odds (95% CI 1.03 – 1.05) of having a comorbid condition in comparison to high-income group.
Conclusions: Income was shown to be a causal factor in a patient’s health and a determinant of the quality of care received even with equitable access to care under a universal health insurance system. Policies focusing on addressing income as an important upstream causal determinant of health to provide support to patients in lower socioeconomic status will be effective in improving health outcomes for this vulnerable social stratum.

Abstract
Background Dicer-like proteins (DCLs) are fundamental players in RNA-silencing mechanisms acting in gene regulation via miRNAs and in antiviral protection in plants, in addition to being related to other biotic and abiotic stresses. Despite be identified in some crops, cotton DCLs weren't characterized until now. Here we characterize the DCLs of three cotton species and analyzed their expression profiles during biotic stress. Results We identified 11 DCLs in the allotetraploid cotton Gossypium hirsutum and 7 and 6 in the diploid G. arboreum and G. raimondii, respectively. Among some DCL duplication observed in these genomes, we observe the presence of an extra DCL3 in the three cotton species, not found in others eudicots until now. All the DCL types identified by in silico analysis in the allotetraploid cotton genome were able to generate transcripts, as observed by gene expression analysis in distinct tissues. Based on the importance of DCLs for plant virus defense, responses of cotton DCLs to virus infection and/or herbivore attack using two commercial cotton cultivars (cv.), one susceptible (Fibermax 966) and another resistant (Delta Opal) to polerovirus CLRDV infection were analyzed. Both cvs. responded differently to virus infection. At the initial stages, 24dpi, the resistant cv. showed strong induction of DCL2a and b, while the susceptible cv. showed a down-regulation of these genes, wherever DCL4 expression was highly induced. Herbivore attack did not induce contrasting profiles between cotton DCLs transcripts in either cotton cv. Conclusions The allotetraploide cotton G. hirsutum has almost all DCLs found in their diploid relative and duplication of DCL2 and DCL3 were found in the three species. All the four classes of DCL respond to aphid attack and virus infection in G. hirsutum, however, remarkable differences in DCL initial responses against the virus itself may be responsible for the virus susceptible and/or resistant phenotype of the contrasting cotton cv. studied.

Abstract
Background : The optimal dosage for cryoablation of atrial fibrillation (Cryo-AF) is still unknown. To evaluate the efficacy of an individualized freeze duration, we compared the clinical outcome of patients treated with a time-to-pulmonary vein isolation (TT-PVI) or temperature-guided ablation protocol to the outcome of patients treated with a conventional ablation protocol. Methods: A total of 164 consecutive patients were included in the study. One method employed was a conventional dosing protocol (at least 2 applications of 180 seconds each)(the Cryo-AF Conventional group n=84), and the second method had a shorter protocol that was based on the TT-PVI or achievement of -40°C within 60 seconds (the Cryo-AF Dosing group n=80). Results: We treated 656 pulmonary veins (PVs) with 1420 cryotherapy applications. The mean number of applications per patient was 8.7±0.8, with no difference between groups (Cryo-AF Conventional , 8.7±0.8 versus Cryo-AF Dosing ,8.6±0.8; P =0.359). The Cryo-AF Dosing group required significantly less total cryotherapy application time (990.60±137.77versus 1501.58±89.60 seconds; P <0.001) and left atrial dwell time (69.91±6.91 versus 86.48±7.03 minutes; P <0.001) than the Cryo-AF Conventional group. Additionally, the Cryo-AF Dosing group required significantly less total procedure time (95.03±6.50 versus 112.43±7.11 minutes; P <0.001). We observed acute ATP-induced or spontaneous vein electric reconnections in 13 veins (1.98%) after 20 minutes. The reconnection rates between the Cryo-AF Conventional and Cryo-AF Dosing groups were similar in that 2.98% and 0.94% of the initially isolated veins were reconnected, respectively, ( P =0.061). There was no difference in the recurrence rate of free atrial arrhythmia after a 1-year follow-up, which were 78.75% in the Cryo-AF Dosing group versus 78.57% in the Cryo-AF Conventional group ( P =0.978). Conclusion: A novel Cryo-AF dosing protocol guided by temperature or the TT-PVI can be used to individualize an ablation strategy. This new protocol can lead to a significant reduction in duration of the procedure, the cryoenergy dosage and the left atrial dwell time. The procedure had equal safety and similar acute and 1-year follow-up outcomes compared to the conventional approach.

Abstract
Background: Dendritic cell-associated C-type lectin-1 (Dectin-1) receptor has been reported to be involved in neuroinflammation in Alzheimer's disease and traumatic brain injury. The present study was designed to investigate the role of Dectin-1 and its downstream target spleen tyrosine kinase (Syk) in early brain injury after ischemic stroke using a focal cortex ischemic stroke model. Methods: Adult male C57BL/6J mice were subjected to a cerebral focal ischemia model of ischemic stroke. The neurological score, adhesive removal test, and foot-fault test were evaluated on days 1, 3, 5, and 7 after ischemic stroke. Dectin-1, Syk, phosphorylated (p)-Syk, tumor necrosis factor-α (TNF-α) and inducible nitric oxide synthase (iNOS) expression was analyzed by western blotting in ischemic brain tissue after ischemic stroke and in BV2 microglial cells subjected to oxygen-glucose deprivation/reoxygenation (OGD/R) injury in vitro. The brain infarct volume and Iba1-positive cells were evaluated using Nissl’s and immunofluorescence staining, respectively. The Dectin-1 antagonist laminarin (LAM) and a selective inhibitor of Syk phosphorylation (piceatannol, PIC) were used for intervention. Results: Dectin-1, Syk, and p-Syk expression was significantly enhanced on days 3, 5, and 7 and peaked on day 3 after ischemic stroke. The Dectin-1 antagonist LAM or Syk inhibitor PIC decreased the number of Iba1-positive cells and TNF-α and iNOS expression, reduced the brain infarct volume and improved neurological functions on day 3 after ischemic stroke. In addition, the in vitro data showed that Dectin-1, Syk, and p-Syk expression was increased following the 3-hour OGD followed by 0, 3, and 6 hours of reperfusion in BV2 microglial cells. LAM and PIC also reduced TNF-α and iNOS expression 3 hours after OGD/R induction. Conclusion: Dectin-1/Syk signaling plays a crucial role in inflammatory activation after ischemic stroke, and further investigation of Dectin-1/Syk signaling in stroke is warranted.
