Published: December 2021

Abstract
Viral infections, including hepatitis C, can cause secondary glomerular nephropathies. Studies suggest that hepatitis C virus infection (HCV+) is a risk factor for chronic kidney disease (CKD) but evidence of this relationship is lacking among Hispanics/Latinos. We examined the association between HCV+ and incident CKD in a prospective cohort of Hispanics/Latinos enrolled in the Hispanic Community Health Study/Study of Latinos. HCV+ was defined by detectable HCV antibodies with additional confirmation through HCV RNA or recombinant immunoblot assay testing. Incident CKD was defined by an estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2 or sex-specific threshold for albuminuria measured during follow-up. We used Poisson regression to estimate incidence rate ratios (IRR) of CKD and changes in eGFR- or albuminuria-based risk stages, separately. We used linear regression to estimate associations with continuous, annualized changes in eGFR and albuminuria.
Over a follow-up period of 5.9 years, 712 incident CKD events occurred among 10,430 participants. After adjustment for demographic characteristics and comorbidities, HCV+ was not associated with incident CKD, defined by eGFR and albuminuria thresholds (IRR 1.29, 95% Confidence Interval 0.61, 2.73). HCV+ was significantly associated with higher eGFR risk stages (IRR 2.39, 95% CI 1.47, 3.61) with most participants transitioning from stage G1 to G2. HCV+ was associated with a continuous, annualized eGFR decline of −0.69 mL/min/m2/year (95% CI −1.23, −0.16). This large, cohort study did not find evidence of a strong association between HCV+ and new-onset CKD among Hispanics/Latinos. HCV infection may not be associated with risk of CKD among Hispanics/Latinos, although treatment with direct-acting antivirals is recommended for all HCV+ individuals, including those with established CKD or end-stage kidney disease.

Abstract
Handrail type and seat height both significantly influence sit-to-stand (STS) movement. However, research on the associations between handrail type, seat height, and their cumulative effect on STS kinematics and changes in plantar pressure distribution during STS under different handrail types and seat heights is insufficient.
The main objective of this study was to investigate the effect of different handrail types and seat heights on the kinematics and plantar pressure in healthy adults during STS.
The study was conducted on 26 healthy young adults. Six conditions were tested: low seat (LS) and vertical handrail; LS and horizontal handrail (HH); LS and bilateral handrail; high seat (HS) and vertical handrail; HSHH; HS and bilateral handrail. The movement time, trunk tilt angle, and time from hindfoot to forefoot peak pressure were analyzed and compared.
A significant difference was found in handrail type (P < .001) and seat height (P < .02) for the total movement time of STS. A significant difference was also found for the maximum trunk tilt angles (P < .001) in handrail types. There was an interaction between handrail type and seat height for the time from hindfoot to forefoot peak pressure of STS (P = .003).
Using HSHH could take less time to accomplish STS movement; it also reduced the maximum trunk tilt angle and thus reduce the risk of falling; the time from hindfoot to forefoot peak pressure when using HSHH was short and subjects could accomplish STS movement easier.
Chylothorax due to central vein thrombosis treated by venous stenting using a dual approach
Authors: Bouche Arthur , De Wispelaere Jean-Francois , Kayser Françoise , Collinge Elodie , Fourneau Hadrien 
Published: December 2021

Abstract

Rationale:
Central vein thrombosis is an uncommon cause of chylothorax, usually secondary to central venous catheterization in association with prothrombotic state causes such as malignancies. In the following case, thrombosis was located in the left brachiocephalic vein and caused recurrent chylothorax resistant to the first line of treatment and successfully treated by percutaneous recanalization using a dual approach.

Patient concerns:
A 52-year-old male patient with current follicular lymphoma undergoing treatment and recent history of COVID-19 pulmonary infection was hospitalized for dyspnea. A chest X-ray revealed extensive bilateral pleural effusion. Analysis of the pleural fluid was compatible with a chylothorax. Iodin injected thoracic computed tomography (CT) revealed a complete left brachiocephalic thrombosis extending to the left axillary vein, with no thoracic mass.

Diagnoses:
Chylothorax due to left brachiocephalic vein thrombosis.

Interventions:
Following an unsuccessful first line of treatment consisting of a low-fat diet, somatostatins and anticoagulation medication, the patient was elected to undergo minimally invasive venous recanalization with stenting. After a first failed attempt of recanalization by femoral access, we successfully crossed the thrombus through brachial access and conducted a dilatation and stenting of the brachiocephalic vein by femoral access, using a “telepheric” method.

Outcomes:
During the 4-month follow up, PET-scanner and chest X-ray demonstrated a significant reduction of the pleural effusion, and the patient reported complete clinical recovery.

Lessons:
Central vein thrombosis is an unusual cause of chylothorax. We report a case of chylothorax complicating a brachiocephalic vein thrombosis successfully treated by percutaneous recanalization and stenting using a dual brachial and femoral approach. No thoracic duct embolization or ligature was required.
SpaceOAR hydrogel spacer injection prior to stereotactic body radiation therapy for men with localized prostate cancer

Published: December 2021

Abstract

Background:
Conventionally fractionated radiotherapy is a common treatment for men with localized prostate cancer. A growing consensus suggests that stereotactic body radiation therapy (SBRT) is similarly effective but less costly and more convenient for patients. The SpaceOAR hydrogel rectal spacer placed between the prostate and rectum reduces radiation-induced rectal injury in patients receiving conventionally fractionated radiotherapy, but spacer efficacy with SBRT is unclear. The purpose of this research was to assess the clinical utility of the hydrogel rectal spacer in men receiving SBRT for prostate cancer.

Methods:
We performed systematic searches of Medline, Embase, and the Cochrane Central Register of Controlled Trials for studies in men who received the SpaceOAR hydrogel spacer prior to SBRT (≥5.0 Gy fractions) for treatment of localized prostate center. Rectal irradiation results were compared to controls without spacer implant; all other outcomes were reported descriptively owing to lack of comparative data incuding perirectal separation distance, rectal irradiation on a dosimetric curve, gastrointestinal (GI) toxicity, and freedom from biochemical failure. GI toxicity was reported as the risk of a grade 2 or 3+ bowel complication in early (≤3 months) and late (>3 months) follow-up.

Results:
In 11 studies with 780 patients, SBRT protocols ranged from 7 to 10 Gy per fraction with total dose ranging from 19 to 45 Gy. Perirectal distance achieved with the rectal spacer ranged from 9.6 to 14.5 mm (median 10.8 mm). Compared to controls receiving no spacer, SpaceOAR placement reduced the radiation delivered to the rectum by 29% to 56% across a dosimetric profile curve. In early follow-up, grade 2 GI complications were reported in 7.0% of patients and no early grade 3+ GI complications were reported. In late follow-up, the corresponding rates were 2.3% for grade 2 and 0.3% for grade 3 GI toxicity. Over 16 months median follow-up, freedom from biochemical failure ranged from 96.4% to 100% (pooled mean 97.4%).

Conclusions:
SpaceOAR hydrogel spacer placed between the prostate and rectum prior to SBRT is a promising preventative strategy that increases the distance between the prostate and rectum, reduces rectal radiation exposure, and may lower the risk of clinically important GI complications.

Abstract

Introduction:
Pulmonary rehabilitation improves the physical condition of patients with chronic respiratory disease; however, there are patients who cannot leave the hospital because of their low activities of daily living (ADLs), despite the completion of primary respiratory disease treatment and rehabilitation during treatment. Therefore, this study demonstrated that those patients recovered their ADLs through in-hospital pulmonary rehabilitation after treatment completion.

Methods:
We prospectively studied 24 hospitalized patients who had some remaining symptoms and showed low ADL scores of 9 points or less on the short physical performance battery after undergoing treatment for respiratory disease in Fukujuji Hospital from October 2018 to October 2019, excluding 2 patients who had re-exacerbation and 1 patient who could not be examined using the incremental shuttle walk test (ISWT). After completion of the primary respiratory disease treatment, patients moved to the regional comprehensive care ward, and they received pulmonary rehabilitation for 2 weeks. In the ward, patients who could not yet leave the hospital could undergo pulmonary rehabilitation for up to 60 days. Data were evaluated three times: upon treatment completion (baseline), postrehabilitation, and 3 months after baseline. The main outcome was an improvement in the incremental shuttle walk test (ISWT) postrehabilitation.

Results:
The median age of the patients was 80 (interquartile range (IQR): 74.8–84.5), and 14 patients (58.3%) were male. The ISWT distance significantly increased postrehabilitation (median [IQR]: 60 m [18–133] vs 120 m [68–203], P < .001). The Barthel Index (BI) (P < .001), the modified Medical Research Council (P < .001), and other scale scores were also improved. Among patients with acute respiratory diseases such as pneumonia, chronic obstructive pulmonary disease, and interstitial pneumonia, ISWT and other data showed improvement at the postrehabilitation timepoint. Ten patients who could perform examinations at 3 months after baseline were evaluated 3 months after taking baseline data prior to starting rehabilitation. The ISWT showed significant improvement 3 months after baseline compared to baseline (P = .024), and the ISWT distance was maintained after rehabilitation.

Discussion and conclusions:
Physical activity, symptoms, mental health, and ADL status in patients who had not recovered after primary treatment completion for respiratory diseases could improve through in-hospital pulmonary rehabilitation.

Abstract

Objective:
Chronic prostatitis (CP) is a common disease in the outpatient department of males and urology. Clinical studies have found that acupuncture combined with traditional Chinese medicine (TCM) has achieved good results in treating CP, but its efficacy and safety are not completely clear. This study aimed to investigate the efficacy and safety of acupuncture combined with TCM in the treatment of CP.

Methods:
Randomized controlled trials of acupuncture combined with TCM in treating CP were screened by searching PubMed, Embase, Cochrane Library, CNKI, etc. The retrieval time was from the database establishment date to March 31, 2021. The Cochrane Collaborative Risk Bias Assessment tool was used to evaluate literature's methodological quality of the literature. The RevMan5.4 software was used for the meta-analysis of outcome indicators. The TSA v0.9 software was used for sequential trial analysis (TSA) of effectiveness.

Results:
In this study, 19 related randomized controlled trial studies were included, with a total of 1831 cases. The results of the meta-analysis showed that acupuncture combined with TCM could significantly improve the clinical efficacy of CP (OR = 3.76, 95%CI: 2.82 to 5.02, P < .00001), reduce the total score of The National Institutes of Health chronic prostatitis symptom index (MD = −4.00, 95%CI: −4.67 to 3.33, P < .00001), and improve patients’ urination symptoms (MD = −1.10, 95%CI: −1.23 to −0.97, P < .00001), alleviated the pain symptoms of patients (MD = −2.38, 95%CI: −2.41 to −2.35, P < .00001), improved the quality of life of patients (MD = −1.69, 95%CI: −1.97 to −1.41, P < .00001), decreased the scores of TCM symptoms of patients (MD = −2.39, 95%CI: −3.45 to −1.33, P < .00001), and did not increase the adverse reactions of patients (MD = 1.09, 95%CI: 0.57 to 2.06, P = .8). The results of publication bias showed that this study was not affected by publication bias, and the conclusion was reliable. TSA showed that acupuncture combined with TCM was effective in treating CP.

Conclusion:
Acupuncture combined with TCM is safe and effective for alleviating CP. It can be used as an effective treatment for chronic prostatitis in the clinic.

Authors: Xu Guangjun , Zheng Jiaoni , Cai Jianghui , Zhang Jing , Liu Jue , Tang Shu 
Published: December 2021

Abstract

Background:
Corticosteroids have been one of the most frequently used therapeutics in ophthalmology over the past decades, known for their potent anti-inflammatory and immunosuppressive actions. Intraocular pressure elevation has proven to be a significant ocular side effect that could accompany steroid use. However, the information on ocular-hypertensive corticosteroid response is scant in children. We aim to systematically describe the corticosteroid-induced intraocular pressure elevation in the pediatric age group.

Methods:
PubMed, Embase, Web of Science, Cochrane Library, Latin American and Caribbean Health Sciences Literature, and the Chinese Biomedical Literature database will be searched for potential articles from database inception to April 29, 2021. No language restrictions will be applied. Studies involving patients less than 18 years old receiving corticosteroids will be included. We will screen abstracts for relevance, extract data, and assess the risk of bias in duplicate. We will rate the certainty of evidence using the Grading of Recommendations Assessment Development and Evaluation approach. The primary outcome will be the intraocular pressure in pediatric patients group. We will provide a narrative synthesis of the findings.

Results:
The systematic review will provide high-quality evidence to assess the relationship between dosage, frequency, route of administration, and duration of corticosteroid on intraocular pressure in children.

Conclusion:
The systematic review will provide evidence to assess the safety of corticosteroid for ocular diseases in pediatric population.

Authors: Rashid Muhammad , Ismail Hammad 
Published: December 2021

Abstract

Background:
To investigate the track of Gujrat, a District of Pakistan is very essential, either it follow-up World Health Organization (WHO) Hepatitis C Virus (HCV) elimination plan or not. This study aimed to find out HCV extinction analysis by time series forecast from District Gujrat, Pakistan.

Methods:
From January 1, 2016 to December 31, 2020 total n-5,111 numbers of HCV real-time polymerase chain reaction (RT-PCR) tests were performed in Gujrat. For extinction analysis we used 2 different models, the first model was seasonal auto-regressive integrated moving average (SARIMA) and the second linear regression (LR) model. First, we fitted both models then these fitted and valid models were used to predict future HCV percentage in District Gujrat.

Results:
In District Gujrat, the men HCV infected ratio is high with a higher viral load as compared with women, from year 2016 to 2020 male to female ratio was (53.75:53.19), (45.67:43.84), (39.67:39.36), (41.94:35.88), (37.70:31.38) respectively. HCV percentage is decreasing from 2016 to 2020 with an average of 4.98%. Our both fitted models SARIMAX (0,1,1)(0,1,1,6) at 95% confidence intervals and LR model Y = –0.379 X + 53.378 at 99% confidence intervals (P-value = .00) revealed that in June 2029 and in August 2027 respectively HCV percentage will be 0 from district Gujrat, Pakistan.

Conclusions:
This study concluded that both SARIMA and LR models showed an effective modeling process for forecasting yearly HCV incidence. District Gujrat, Punjab, Pakistan is on track to achieve the WHO HCV elimination plan, before 2030 HCV will be extinct from this region.
The Effects of Daily Digital Device Use on the Ocular Surface in Healthy Children
Authors: Kazanci Burcu , Eroglu Fatma Corak 
Published: December 2021

SIGNIFICANCE
Digital device usage among children has increased significantly in recent years. Prolonged screen exposure can have adverse effects on the eye, especially on the ocular surface.

PURPOSE
We aimed to evaluate the duration of screen exposure and its effect on the ocular surface in healthy children aged 10 to 18 years.

METHODS
This cross-sectional observational study included 200 healthy children. Screen exposure times of the children were ascertained, and the effect of screen exposure on the ocular surface was evaluated using tear breakup time, kerato-epitheliopathy (Oxford) score, and Schirmer test. The Ocular Surface Disease Index (OSDI) was used to assess subjective dry eye symptoms. Findings for subjects with a daily screen exposure time of fewer than 2 hours were compared with those reporting more than 2 hours of screen time. Statistical evaluation included the Shapiro-Wilk test, Student t test, and Pearson correlation analysis.

RESULTS
The mean ± standard deviation (SD) age was 14 ± 2.6 years, and 88.5% of the participants used mobile phones or computers every day. The mean ± SD tear breakup time was 10.3 ± 4.1 seconds, and the Schirmer test score was 15.6 ± 4.7 mm. The Oxford score was 0.4 ± 1, and no corneal staining was detected in 83.5% of the subjects. The mean ± SD OSDI score was 23.5 ± 17.8, and 67.5% of subjects had a mild-to-severe ocular surface disease. When daily screen exposure times less than and greater than 2 hours were compared, there was no statistically significant difference between the two groups in tear breakup time, Schirmer test, Oxford score, and OSDI score. Whereas there was a statistically significant weak positive correlation (r = 0.307, P = .001) between OSDI score and screen exposure time, there was no correlation between tear breakup time, Schirmer test, and Oxford score and screen exposure time.

CONCLUSIONS
Screen exposure in healthy children may cause ocular surface symptoms without causing changes in ocular surface findings.
Shear Wave Elastography in the Differentiation of Nonfibrotic Versus Fibrotic Liver Disease in Children: A Prospective Study With Histological Correlation
Authors: Hebelka Hanna , de Lange Charlotte , Boström Håkan , Ekvall Nils , Lagerstrand Kerstin 
Published: December 2021

Objectives:
To evaluate the diagnostic accuracy of ultrasound shear wave elastography (SWE) prospectively and to determine cutoff value for nonfibrotic liver tissue in children with suspected or established liver disease.

Methods:
In 90 consecutive pediatric patients, standardized 2D-SWE was performed during general anesthesia and free breathing. Liver stiffness was estimated with SWE followed by a percutaneous biopsy from the corresponding area. SWE values were compared with histology with fibrosis scored according to Batts & Ludwig classification (grade 0–4 = F0–F4) and to hepatic biomarkers.

Results:
Four patients with SWE interquartile range (IQR)/median ≥ 30% kPa were excluded. The remaining 86 children (59% males) had a mean age = 10.2 years (0.1–18). The distribution of individuals with median (min;max) SWE values (kPa) within each fibrosis grade were; F0[n = 10; 5.0(3.4;6.3)], F1[n = 24; 5.0(3.6;8.7)], F2[n = 32; 5.8(3.5;13.4)], F3[n = 12, 7.5(4.0;14.4)], and F4[n = 8; 12.5(6.6;21.0)]. There was a significant difference between fibrosis grades (0.03 > P < 0.002) except between F0 and F1 respectively between F1 and F2. The AuROC differentiating F0-1 from F2-4 was 0.77(95% CI: 0.67-0.87). A cutoff SWE value of ≤4.5 kPa yielded 90% sensitivity and 68% specificity to rule out significant fibrosis (F2–F4). Out of the 18 children (21%) with SWE value ≤4.5 kPa, 12 had grade F0-1 and 6 had F2, although including some confounders for increased SWE measurements as steatosis/hepatitis/cholestasis.

Conclusions:
2D-SWE ultrasound can reliably distinguish no/mild (F0/F1) from moderate/severe (F2–F4) fibrosis in children with suspected/established liver disease with good sensitivity and acceptable specificity. Our results show that in pediatric patients, when the indication for biopsy is to rule out significant fibrosis, SWE can be considered an alternative.
