Authors: Wang Peidong , Peng Yanyan , Guo Yueqin , Zhao Yongqiang 
Published: June 2021

Abstract

Background:
Probiotics supplementation has emerged as adjuvant therapy for chronic kidney disease (CKD) in recent years. However, the effects of probiotic preparations on serum inflammatory cytokine levels are still highly controversial and poorly documented. Therefore, we performed the protocol for systematic review and meta-analysis to further clarify the effects of probiotic preparations in CKD patients.

Methods:
This review will develop following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement guidelines. We searched literature published until May, 2021 thoroughly in PUBMED, Scopus, EMBASE, Web of Science, and Cochrane Library databases on May, 2021. The risk of bias of included studies was estimated by taking into consideration the characteristics including random sequence generation, allocation concealment, blinding of patients, blinding of outcome assessment, completeness of outcome data, selective reporting, and other bias by Cochrane Collaboration's tool for assessing the risk of bias. Data synthesis and analyses were performed using Stata version 10.0 software.

Results:
The results of this systematic review and meta-analysis will be published in a peer-reviewed journal.

Conclusion:
We hypothesized that probiotic preparations may decrease the serum levels of inflammatory cytokines and protect the intestinal epithelial barrier of patients with CKD.

Published: June 2021

Abstract

Background:
The COVID-19 pandemic has rapidly spread to other countries, causing numerous deaths and challenges for organizations and health professionals. Diet and nutrition invariably influence the competence of the immune system and determine the risk and severity of infections. Studies have already been published on the relationships through which vitamins C and D can mitigate the severity of infections such as COVID-19. In this context, this protocol describes a systematic review intended to analyze if vitamin C and D supplementation can reduce the severity of Covid-19.

Methods:
This protocol was developed based on the recommendations of PRISMA-P. In order to accomplish the systematic review, we will carry out searches in the PubMed, Web of Science, Scopus, Cochrane, and ScienceDirect databases in the quest for control case studies that analyze the supplementation and evolution of patients with COVID-19. There will be no limitations related to language or publication time. The searches will be carried out by 2 independent researchers who will select the articles, and then the duplicate studies will be removed, while the suitable ones will be selected using the Rayyan QCRI application. In order to assess the risk of bias, we will use the instrument proposed by the National Heart, Lung and Blood Institute. Moreover, we will carry out metaanalyses and subgroup analyses according to the conditions of the included data.

Results:
This review will assess the association between vitamin C and D supplementation and the reduction in the severity of COVID-19.

Conclusion:
The findings of this systematic review will summarize the latest evidence for the association between vitamin C and D supplementation and COVID-19 through a systematic review and meta-analysis.

Abstract
We investigated the temporal trends of short-term mortality (death within 1 year of diagnosis) and cause-specific deaths in human immunodeficiency virus (HIV)-infected persons by stage of HIV infection at diagnosis. We also assessed the impact of late diagnosis (LD) on short-term mortality.
Epidemiological records of HIV-infected Singapore residents from the National HIV Registry were linked to death records from the Registry of Births and Deaths for observational analyses. Newly-diagnosed HIV cases with available cluster of differentiation 4 count at time of diagnosis in a 5-year period from 2012 to 2016 were included in the study. Hazard ratios (HRs) and 95% confidence interval (CI) of LD for all deaths excluding suicides and self-inflicted or accidental injuries, and HIV/ acquired immunodeficiency syndrome (AIDS)-related deaths occurring within 1 year post-diagnosis were calculated using Cox proportional hazards regression models with adjustment for age at HIV/AIDS diagnosis. Population attributable risk proportions (PARPs) were then calculated using the adjusted HRs.
Of the 1990 newly-diagnosed HIV cases included in the study, 7.2% had died by end of 2017, giving an overall mortality rate of 2.16 per 100 person-years (PY) (95% CI 1.82–2.54). The mortality rate was 3.81 per 100 PY (95% CI 3.15–4.56) in HIV cases with LD, compared with 0.71 (95% CI 0.46–1.05) in non-LD (nLD) cases. Short-term mortality was significantly higher in LD (9.1%) than nLD cases (1.1%). Of the 143 deaths reported between 2012 and 2017, 58.0% were HIV/AIDS-related (nLD 28.0% vs LD 64.4%). HIV/AIDS-related causes represented 70.4% of all deaths which occurred during the first year of diagnosis (nLD 36.4% vs LD 74.7%). The PARP of short-term mortality due to LD was 77.8% for all deaths by natural causes, and 87.8% for HIV/AIDS-related deaths.
The mortality rate of HIV-infected persons with LD was higher than nLD, especially within 1 year of diagnosis, and HIV/AIDS-related causes constituted majority of these deaths. To reduce short-term mortality, persons at high risk of late-stage HIV infection should be targeted in outreach efforts to promote health screening and remove barriers to HIV testing and treatment.

Published: June 2021

Abstract
We aimed to evaluate sarcopenia and sarcopenic obesity (SO) in patients with type 2 diabetes mellitus (T2DM), possible relationships with serum irisin and myostatin levels, and the effect of glycemic control on SO.
Ninety T2DM patients were included in this a cross-sectional study. Sarcopenia was determined by evaluating muscle mass (bioelectrical impedance analysis), muscle strength (HGS), and gait speed (GS). Patients with muscle mass loss with functionally reduced muscle strength and/or performance were considered sarcopenic. In addition, participants were divided into 3 groups according to the FM (fat mass)/FFM (fat-free mass) ratio [group 1:5th-50th percentiles; group 2:50th-95th percentiles and group 3: ≥95 percentiles (sarcopenic obese)]. Irisin, myostatin levels and metabolic parameters were measured in all patients.
The prevalence of sarcopenia and SO was 25.6% and 35.6%, respectively. Irisin levels were lower in sarcopenic patients, while glycosylated hemoglobin (A1c), body mass index (BMI), FM, and FM index were higher (P < .05). From group 1 to group 3, BMI, FM, FM index, GS, myostatin, and A1c increased, and muscle mass percentage, HGS, and irisin decreased (P < .05). A positive correlation was found between FM/FFM and myostatin and a negative correlation between FM/FFM and irisin (r = 0.303, P = .004 vs. r = −0.491, P < .001). Irisin remained an important predictor of SO, even after adjusting for confounding variables (OR:1.105; 95% CI:0.965–1.338, P = .002). The optimal cut-off value for irisin to predict SO was 9.49 ng/mL (specificity = 78.1%, sensitivity = 75.8%). In addition, A1c was an independent risk factor for SO development (OR:1.358, P = .055).
This study showed that low irisin levels (<9.49ng/mL) and poor glycemic control in T2DM patients were an independent risk factor, especially for SO.
Comparison of the sensitivity of mammography, ultrasound, magnetic resonance imaging and combinations of these imaging modalities for the detection of small (≤2 cm) breast cancer

Published: June 2021

Abstract
The aim of this study was to compare the sensitivity of mammography (MG), ultrasound (US), magnetic resonance imaging (MRI), and combinations of these imaging modalities for the detection of small (≤2 cm) breast cancer and to evaluate the benefit of preoperative breast MRI after performing conventional imaging techniques for small breast cancer.
This was an observational retrospective review of 475 patients with pathologically confirmed breast cancer. We reviewed the medical records; assessed the preoperative reports of MG, US, and MRI; and categorized them as benign features (BI-RADS 1–3) or malignant features (BI-RADS 4 or 5). The criterion standard for detection was the pathologic assessment of the surgical specimen. The sensitivities of the different techniques were compared using the McNemar test.
Among the 475 women, the sensitivity of MG was significantly greater in patients with low breast density than in those with high breast density (84.5% vs 65.8%, P < .001). US had higher sensitivity than MG (P < .001), and the combination of MG + US showed better sensitivity than MG or US alone (P < .001). Further addition of MRI to the combination of MG and US statistically contributed to the sensitivity yield (from 93.3% to 98.2%; P < .001) but did not significantly increase the mastectomy rate (from 48.2% to 49.3%; P = .177).
MG has limited diagnostic sensitivity in patients with small breast cancer, especially in those with dense breast tissue. US is better than MG at detecting small breast cancer, regardless of breast density. The addition of MRI to MG and US could increase sensitivity without increasing the mastectomy rate. This study suggests performing MRI routinely on the basis of MG and US for small (≤2 cm) breast cancer.

Published: June 2021

Abstract
Post-acute care (PAC) is a type of transitional care for poststroke patients after the acute medical stage; it offers a relatively intensive rehabilitative program. Under Taiwan's National Health Insurance guidelines, the only patients who can transfer to PAC institutions are those who have had an acute stroke in the previous month, are in a relatively stable medical condition, and have the potential for improvement after aggressive rehabilitation. Poststroke patients receive physical, occupational, and speech therapy in PAC facility. However, few studies have evaluated the effects of PAC in poststroke patients since PAC's initiation in Taiwan. Thus, this study aims to investigate whether the length of stay in a PAC institution correlates with patients’ improvements.
This retrospective and single-center study in Taiwan enrolled 193 poststroke patients who had received acute care at Chi-Mei Medical Center, Taiwan, at any period between 2014 and 2017. Data on their length of stay in the PAC institution were collected. Poststroke patients’ functional ability—such as activities of daily living (ADL) function and swallowing ability—as well as their corresponding scales were assessed on the first and last day of PAC stay. Statistical analysis was conducted by SPSS version 21.0 .
The average duration of PAC stay was 35.01 ± 16.373 days. Duration of PAC stay was significantly positively correlated with the Barthel index (P < .001), Berg balance test score (P < .001), gait speed (P = .002), and upper sensory function and upper motor function within the Fugl–Meyer Assessment (both P < .001).
Poststroke patients with longer stay in a PAC institution had superior ADL function, balance and coordination, walking speed, and upper-limb dexterity and sensory function.
Vertebral Artery Dissection in a Woman Due to Golf
Authors: Gallaer Alexander , Archambault Simon , Patel Smit D. , Mui Gracia 
Published: June 2021

Introduction:
Traditionally, spontaneous cervical artery dissections have been associated with violent, sudden neck movements. These events are a significant cause of stroke related morbidity, particularly in young people. Only a handful of cases of golf-induced vertebral artery dissection (VAD) have been described, and the discussion has primarily focused on middle-aged men. Despite the discussion focused on this demographic, women are participating in golf at higher rates than ever before, and have a higher risk for developing VAD.

Case Report:
A 41-year-old woman presented to our hospital with sharp neck pain, dizziness, and ptosis after swinging a driver during a morning round of golf. Imaging demonstrated a right V3/V4 VAD and subsequent ischemic infarction. After administration of tissue plasminogen activator she had abrupt change in mental status with seizure-like activity. She underwent angiogram and mechanical thrombectomy, and was started in heparin 24 hours post-tissue plasminogen activator. This was subsequently changed to low-dose aspirin following thalamic petechial hemorrhage. She was discharged from the hospital after a few days with only minor deficits. We will discuss mechanism, treatment, and outcomes of VAD in context of this case.

Conclusion:
This patient is the first woman in the literature to suffer from VAD as a result of playing golf. The twisting motion of the head and neck in a golf swing may be a risk factor for dissection and subsequent development of stroke. As a result of increased female participation in golf, we expect to see increased incidence of women presenting with “golfer’s stroke” in coming years.

Published: June 2021

Background

Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) case surveillance relies on reported positive laboratory results. Changes in reported cases may represent changes in testing practice or infection prevalence. This study evaluated changes over time for CT and NG positivity and testing rates of pregnant persons.

Methods
Prenatal testing results from persons aged 16 to 40 years tested by a national reference clinical laboratory were analyzed for CT and NG testing and positivity from 2010 to 2018 (n = 3,270,610).

Results
Testing rates increased among pregnant persons for CT (from 56.3% in 2010 to 64.1% in 2018, P < 0.001) and NG (from 55.6% to 63.2%, P < 0.001). Higher CT testing rates were found in Black non-Hispanic (adjusted odds ratio [AOR], 1.58; 95% confidence interval [CI], 1.57–1.60) and Hispanic (AOR, 1.19; 95% CI, 1.18–1.20) persons. NG and CT testing rates were virtually identical. Significant increasing trends in CT positivity were observed for each age group studied (P < 0.001 for all): 16–19 (from 11.7% to 13.0%), 20–24 (from 6.4% to 6.7%), 25–30 (from 1.9% to 2.4%), and 31–40 years (from 0.76% to 0.92%). Black non-Hispanic persons had the highest positivity for CT (AOR, 2.52; 95% CI, 2.46–2.57) and NG (AOR, 5.42; 95% CI, 5.05–5.82).

Conclusions
Testing and adjusted positivity for both CT and NG among pregnant persons increased from 2010 to 2018. Higher testing rates were observed in Black non-Hispanic and Hispanic persons (even in persons younger than 25 years), suggesting some testing decisions may have been based on perceived risk, in contrast to many guidelines recommending screening all pregnant persons younger than 25 years.
Recurred Sphenoethmoidal Mucocele After Treated With Simple Endoscopic Marsupialization
Authors: Lee Seon-Min , Lee Ki-Il 
Published: June 2021

Abstract
Paranasal sinus mucocele is a mostly benign disease but can cause irreversible complications depending on its location. A sphenoethmoidal mucocele (SEM) can cause compressive neuropathy due to its proximity to the optic nerve. Urgent endoscopic marsupialization is considered the treatment of choice for SEM. However, there is a scarcity regarding recurrence or operative size. Herein, the authors report a case of SEM that recurred after small endoscopic drainage. The patient was reoperated with wide cyst removal and nasal cavity ventilation expansion. Vision was partially resolved, and no recurrence was reported in the 6-month follow-up period.
Primary Repair of Bilateral Cleft Lip Deformity and Absent Prolabium With a Full-Thickness Skin Graft
Authors: Loh Ian , Chong David 
Published: June 2021

Abstract
Bilateral cleft lip deformities makeup 10% of orofacial clefts and are uncommon when compared to unilateral cleft lip.
1,2
These cleft deformities have significant physical and long-term psychosocial effects on not only the patient but their family. With bilateral cleft lip deformity, the cutaneous approximation of the lateral lip segments are dependent on a sufficient prolabium to reconstruct the philtrum.

Deficient skin equates to tight midline closure and subsequent unsightly scarring
In the subclinical phenotype of bilateral cleft lip and palate, where the patient has an absent or deficient prolabium, achieving tension free closure in the primary surgical setting is a reconstructive dilemma.

This clinical report describes the use of a full-thickness skin graft to reconstruct the philtrum in a 12-month-old boy with bilateral cleft lip deformity, absent prolabium, absent columella and absent nasal septum to provide an aesthetic subunit repair.
A Single-Center Retrospective Review of Perioperative Complications and Reoperation Rates Between Open Cranial Vault Remodeling and Distraction Osteogenesis for Unilateral Coronal Craniosynostosis

Published: June 2021

Background:
Unilateral coronal craniosynostosis (UCS) is the third most prevalent form of craniosynostosis. Traditional treatment of UCS has been achieved with fronto-orbital advancement and cranial vault remodeling (FOAR), but utilization of cranial distraction osteogenesis (DO) techniques has increased. This study aims to compare perioperative complications and reoperation trends in FOAR versus DO techniques at a single institution.

Methods:
An Institutional Review Board-approved retrospective review was performed from January 1999 to November 2018 at a single institution. Patients were those that have undergone FOAR or DO with an anterior rotational flap technique as previously described. Indications for secondary procedures included: contour deformities, relapse, surgical site infection, and persistent cranial defects.

Results:
Eighty-one patients with UCS were identified, 64 patients underwent FOAR and 17 patients underwent DO. When perioperative characteristics were compared, patients who underwent DO were younger in age, however, there was no significant difference in transfusion requirement or length of stay between patient cohorts. Surgery time was increased in DO patients. When perioperative complications were compared, more intraoperative dural tears were observed in the FOAR cohort. When unplanned reoperation rates were compared, patients who had undergone FOAR had a statistically significant higher reoperation rates at 5 years of follow up. When including routine distractor removal as a reoperation, reoperative rate was increased in the DO cohort. No difference in reoperation rates was noted at 5 years following index operation.

Conclusions:
The safety profile of DO is similar to that of traditional FOAR techniques for treatment of UCS. Longer-term follow-up studies are needed to elucidate whether outcomes are durable, but the unplanned reoperation rate in DO is less than that of FOAR at 5 years and presents several advantages that warrants its use in patients with UCS.
Craniometric and Volumetric Analysis of Posterior Vault Distraction Osteogenesis: 10 Year Update
Authors: Zapatero Zachary D. , Kalmar Christopher L. , Kosyk Mychajlo S. , Carlson Anna R. , Swanson Jordan W. , Bartlett Scott P. , Taylor Jesse A. 
Published: June 2021

Purpose:
The purpose of this study is to quantitatively establish the volumetric changes observed with posterior vault distraction osteogenesis in the anterior, middle, and posterior thirds of the cranial vault; characterize change in cranial length, width, and height, correlating these changes to demographic variables that may help identify why younger kids gain more volume; and describe the short-term position of the transport segment.

Methods:
Multisuture craniosynostosis patients who underwent posterior vault distraction osteogenesis were retrospectively reviewed. Pediatric, dose-reduced, thin cut helically acquired head computed tomography scans were analyzed on Materialise Mimics v22 (Materialise, Ghent, Belgium). Pre and post-PVDO and “old” and “young” cohort were compared.

Results:
Twenty-one patients met inclusion criteria. The change in cranial length was significantly less at a median of 14.9 mm [Interquartile range (IQR) 11.8, 31.6] compared to the X-ray measured AP distraction distance (30 mm [IQR 24, 33]; P < 0.001) and significantly less than the theoretically calculated distance (23 mm [IQR 19, 31]; P = 0.012). Median anterior cranial height was shorter post PVDO (82.9 mm, [IQR 64.8, 92.6] versus 78.7 mm [IQR 57.0, 88.7]; P = 0.030). The younger cohort saw a greater increase in total intracranial volume (median 335.1 mL [IQR 163.2, 452.3, median 37.1%] versus 144.6 mL [IQR 119.0, 184.8, median 12.0%]; P = 0.011).

Conclusions:
This is the first study to quantify volumetric changes to the anterior, middle, and posterior cranial vaults and demonstrates benefits of preforming PVDO at a younger age to help control turricephaly and produce greater percentage volumetric increases.
