Authors: Greenstein Steven A. , Yu Austin S. , Gelles John D. , Huang Steven , Hersh Peter S. 
Published: August 2023

Objectives:
To report on the topographic and visual outcomes 10 years after corneal cross-linking in patients with progressive keratoconus and corneal ectasia after refractive surgery.

Methods:
Cross-sectional cohort study of an original, prospective, randomized, clinical trial. Patients treated in a single center cornea and refractive surgery practice as part of the U.S. pivotal trials, which led to the Food and Drug Administration approval of corneal cross-linking, were recruited for a 10-year follow-up examination. LogMar lines (LL) of uncorrected visual acuity (UCVA) and best spectacle–-corrected visual acuity (BSCVA), maximum keratometry, and thinnest pachymetry were evaluated. In addition, the Belin ABCD progression display was used to determine progression (95% confidence interval) of the anterior curvature, posterior curvature, and corneal thickness of each individual eye included.

Results:
Nineteen eyes of 13 patients treated with standard cross-linking returned for a 10-year follow-up examination. Mean maximum keratometry changed from 58.2±12.0 diopters (D) to 58.3±10.1 D, thinnest pachymetry changed from 440.6±51.6 µm to 442.3±54.4 μm, UCVA changed from 0.79±0.42 LL to 0.86±0.46 LL, and BSCVA changed from 0.38±0.26 LL to 0.33±0.34 LL, 10 years after cross-linking. Individually, 68.5% of the entire cohort, 81.8% of keratoconus eyes, and 50% of eyes with corneal ectasia remained topographically stable 10 years after standard cross-linking.

Conclusions:
In the entire cohort, visual acuity and topography remained stable 10 years after cross-linking. Over the long-term, eyes with keratoconus seem to be more stable than those with corneal ectasia.

Published: August 2023

Précis:
The prevalence of glaucoma in the adult population included in this study was 2.3%. Normal values of routine eye examinations are provided including age and sex variations.

Purpose:
The purpose of this study was to analyze the prevalence of glaucoma in a very large database.

Methods:
Retrospective analysis of medical records of patients examined at the Medical Survey Institute of a tertiary care university referral center between 2001 and 2020. A natural language process (NLP) algorithm identified patients with a diagnosis of glaucoma. The main outcome measures included the prevalence and age distribution of glaucoma. The secondary outcome measures included the prevalence and distribution of visual acuity (VA), intraocular pressure (IOP), and cup-to-disc ratio (CDR).

Results:
Data were derived from 184,589 visits of 36,762 patients (mean age: 52 y, 68% males). The NLP model was highly sensitive in identifying glaucoma, achieving an accuracy of 94.98% (area under the curve=93.85%), and 633 of 27,517 patients (2.3%) were diagnosed as having glaucoma with increasing prevalence in older age. The mean VA was 20/21, IOP 14.4±2.84 mm Hg, and CDR 0.28±0.16, higher in males. The VA decreased with age, while the IOP and CDR increased with age.

Conclusions:
The prevalence of glaucoma in the adult population included in this study was 2.3%. Normal values of routine eye examinations are provided including age and sex variations. We proved the validity and accuracy of the NLP model in identifying glaucoma.
Leukocyte 8-hydroxy-2′-deoxyguanosine as an oxidative stress marker to predict cardiovascular events and death in chronic hemodialysis patients
Authors: Tang Ching-Fang , Wu Mei-Yi , Wei Yau-Huei , Ho Yang , Kuo Ko-Lin 
Published: August 2023

Background:
Hemodialysis patients have a markedly increased risk of cardiovascular (CV) morbidity and mortality. Oxidative stress plays a pathogenic role in the progression of atherosclerosis and CV disease among chronic hemodialysis patients. The 8-hydroxy-2′-deoxyguanosine (8-OHdG) content in leukocyte deoxyribonucleic acid (DNA) has been shown as a sensitive and well-known biomarker of oxidant-induced DNA damage in chronic hemodialysis patients.

Methods:
We conducted a retrospective cohort study to investigate the association of leukocyte 8-OHdG and CV events and deaths in patients of chronic hemodialysis. In this study, 217 chronic hemodialysis patients were recruited from 2016 to 2021. The 8-OHdG content of leukocyte DNA was measured by a high-performance liquid chromatography electrochemical detection method. Study outcomes were CV events as well as CV and all-cause deaths. The patients were followed until May 2021.

Results:
The median follow-up period was 34.8 months. At the end of May 2021, 57 first CV events and 89 all-CV events occurred. Among the first and all CV events, 17 (29.8%) and 32 (36.0%) were fatal, respectively. Multivariate Cox regression analysis showed per 1/105 dG increment in leukocyte 8-OHdG values increased risk of CV events (adjusted hazard ratio [aHR], 1.19; 95% CI, 1.10-1.41; p < 0.001), CV death (aHR, 1.27; 95% CI, 1.03-1.72; p = 0.034), and all-cause death (aHR, 1.11; 95% CI, 1.01-1.30; p = 0.038).

Conclusion:
This is the first study to demonstrate that oxidative stress assessed by 8-OHdG levels of leukocyte DNA predicted CV events as well as CV and all-cause deaths among chronic hemodialysis patients.
Postauricular versus systemic use of steroids for sudden hearing loss: A systematic review and meta-analysis of randomized controlled trials
Authors: Deng H.S. , Hou Y.W. , Zhang J.N. , Yang T. 
Published: August 2023

Background:
Sudden sensorineural hearing loss (SSNHL) can be debilitating and is one of the most common otological diseases. Steroids play an important role in its treatment. There are many ways to administer steroids, and the efficacy and safety of different administration routes remain unclear. This meta-analysis aimed to investigate the effect and safety of different types of steroid delivery administration for the treatment of SSNHL.

Methods and analysis:
We searched the Weipu, Wanfang, Chinese Biomedical Literature, National Knowledge Infrastructure, Web of Science, Embase and PubMed databases for randomized controlled trials (RCTs) on glucocorticoid treatments for SSNHL to compare the efficacy of postauricular injection and systemic steroid administration. Review Manager 5.4 software was used for data synthesis, which included the recovery rate (RR) of reported hearing improvement and change level in pure-tone audiometry (PTA). Subgroup analyses were performed based on different drugs, basic treatment, initial PTA, drug administration methods, onset time, and treatment course. Stata 15.1 software was used for analyses of publication bias and sensitivity.

Results:
Our meta-analysis included 38 studies involving 3609 patients with SSNHL. In all included studies, the risk difference (RD) using reported improvement as an outcome measure was 0.12 for postauricular injection administration compared with systemic therapy (95% confidence interval [CI] = 0.008, 0.16, P < .00001, I2 = 59%). When examining PTA changes as an outcome measure (19 studies), the mean difference was 6.06 (95% CI = 3.96, 8.16, P < .00001, I2 = 70%). The RD for hearing improvement was compared among different factors, and the results showed that postauricular injection is superior to systemic steroid administration.

Conclusion:
Postauricular injection may be safer and more effective treatment than systemic therapy as a treatment for SSNHL.
The readmission of a parturient with natural delivery after discharge due to residual fetal membrane: A case report
Authors: Wang Yonghong , Li Juan , He Qiuyang , Ren Jianhua , Wang Guoyu 
Published: August 2023

Rationale:
Placental residue is a relatively common and sophisticated disease among obstetric delivery complications. A failure to detect placental residue in time may cause poor outcomes such as postpartum hemorrhage and puerperal infection.

Patient concerns:
We present the case of a 33-year-old full-term singleton parturient with placental residue. Upon precipitate labor and childbirth, the placenta and fetal membranes were examined to be intact. However, 1 day after discharge, she felt that there was discharge from the vagina and thus presented to our emergency department.

Diagnoses:
The patient was diagnosed with residual membranes and readmitted to the hospital for uterine curettage.

Intervention:
Uterine curettage was performed under B-ultrasound guidance.

Outcome:
The patient was discharged smoothly without any postoperative complications.

Lessons:
This paper can provide significant enlightenment for the prevention and early treatment of placental residue, including enhancing the risk awareness of high-risk patients, standardizing the process of clinical examination of the placenta, and early uterine contraction promotion to assist in the discharge of residual tissue, so as to reduce the occurrence of placental residue.
Assessment of corticospinal tract remodeling based on diffusion tensor imaging in the treatment of motor dysfunction after ischemic stroke by acupuncture: A meta-analysis
Authors: Zhu Weiming , Deng Shizhe , Jiang Hailun , Zhang Jieying , Li Boxuan , Jia Qingqing , Meng Zhihong 
Published: August 2023

Background:To investigate the efficacy of acupuncture in improving motor dysfunction after ischemic stroke (IS) and to investigate the effect of acupuncture on corticospinal tract (CST) remodeling using diffusion tensor imaging.Methods:Published literature on the effect of acupuncture on CST remodeling after IS using diffusion tensor imaging in the form of randomized controlled trials (RCTs) were systematically retrieved and screened from Cochrane Library, Web of Science, PubMed, Embase, CNKI, CBM, VIP, and Wanfang databases from inception to December 2022. The methodological quality of the included studies was critically and independently evaluated by 2 reviewers using the Cochrane Risk of Bias Assessment Tool for RCTs. The correlated data were extracted using the pre-designed form, and all analyses were performed using Reviewer Manager version 5.4.Results:Eleven eligible RCTs involving 459 patients were eventually included. The combined evidence results showed that the acupuncture group significantly improved patients’ National Institute of Health stroke scale, Fugl-Meyer Assessment Scale, and Barthel index compared with conventional medical treatment. The acupuncture group significantly promoted remodeling of the CST, as reflected by an increase in fractional anisotropy (FA) throughout the CST [MD = 0.04, 95% CI (0.02, 0.07),P= .001], and in addition, subgroup analysis showed that the acupuncture group significantly improved FA in the infarct area compared with conventional medical treatment at around 4 weeks [MD = 0.04, 95% CI (0.02, 0.06),P= .0002] and FA of the affected cerebral peduncle [MD = 0.03, 95% CI (0.00, 0.07),P= .02]. Also, compared with conventional medical treatment, the acupuncture group significantly increased average diffusion coefficient of the affected cerebral peduncle [MD = −0.21, 95% CI (−0.28, −0.13),P< .00001].Conclusion:The results of the meta-analysis suggest that acupuncture therapy can improve the clinical manifestations of motor dysfunction in patients after IS and advance a possibly beneficial effect on CST remodeling. However, due to the number and quality of eligible studies, these findings need to be further validated in more standardized, rigorous, high-quality clinical trials.

Published: August 2023

Pyrrolizidine alkaloids induced hepatic sinusoidal obstruction syndrome (PA-HSOS) often occurs after consuming herbs or a dietary supplement containing the plant Tu-San-Qi. Limited data exists to identify patients with fatal outcomes for early interventions. We aimed to analyze the predictors for 3-month survival. We retrospectively enrolled PA-HSOS patients in 5 hospitals and extracted data from the onset of PA-HSOS to 36 months. Outcome measurements were 3-month and 36-month survival rates, baseline prognostic predictors for survival, and the effects of anticoagulant therapy. Among 49 enrollees, the median age was 60 and 49% male. At the onset of PA-HSOS, patients with Child-Turcotte-Pugh (CTP) class of A, B, or C were 8.2% (4/49), 42.8% (21/49) and 49.0% (24/49), respectively. None of them received a transjugular intrahepatic portosystemic shunt or a liver transplant. The 3-month and 36-month survival rates were 86% and 76%, respectively. Compared to the CTP class A or B, class C at baseline independently predicted lower survival rates at both 3 and 36 months. However, anticoagulation therapy treatment within the first 3 months independently predicted significantly higher survival rates at both time points. CTP class C and anticoagulant therapy were the independent predictors for short-term and long-term survival. Anticoagulant therapy could decrease mortality rate of CTP class C patients.
The greatest benefit of anticoagulant evaluated by 3-month survival rate was in patients with CTP class C compared with those without treatment (93% vs 40%, P = .009). There were no bleeding complications reported in patients treated with the anticoagulant.
Recurrent squamous cell carcinoma arising in ovary mature cystic teratoma: A case report
Authors: Ji Xuechao , Zhai Peiling , Yang Hanchao , Wang Hui , Wang Xinbo 
Published: August 2023

Rationale:
Malignant transformation of mature cystic teratoma is very rare, of which squamous cell carcinoma (SCC) is the most common type. Prognosis of SCC arising in mature cystic teratoma of the ovary is very poor. Our experience may provide new ideas for the treatment of this disease.

Patient concerns:
The patient was a 56-year-old woman and was admitted for a lower abdominal pain. She underwent a laparoscopic surgery with 4 cycles of chemotherapy and had achieved a complete response; 10 months after the completion of initial treatment, her cancer relapsed. She underwent a cytoreductive surgery with concurrent chemoradiotherapy and has achieved a complete response again.

Diagnoses:
This patient was initially diagnosed with ovarian cancer (stage IIIB) arising from malignant transformation of mature teratoma; 10 months after the completion of initial treatment, she was diagnosed with recurrent ovarian cancer.

Interventions:
This patient was initially treated with laparoscopic bilateral salpingo-oophorectomy. After histopathological confirmation that she had ovarian cancer, she underwent laparoscopic total hysterectomy and omentectomy with 4 cycles of chemotherapy. After her ovarian cancer recurred, she underwent open cytoreductive surgery and concurrent chemoradiotherapy.

Outcomes:
The patient achieved complete response after both initial and relapsed treatment.

Lessons:
Optimal cytoreduction and concurrent chemoradiotherapy may be an option to improve the prognosis of patients with recurrent SCC arising in ovary mature cystic teratoma.
A comprehensive meta-analysis on the association between vitamin C intake and gestational diabetes mellitus: Insights and novel perspectives
Authors: Zhou Lili , Liu Junbo , Zhou Min 
Published: August 2023

Background:
Gestational Diabetes Mellitus (GDM) is a significant health concern in pregnant women and their offspring. Although Vitamin C is known to play a role in maintaining normal physiological processes, its relationship with GDM has not been fully elucidated.

Methods:
We conducted a systematic review and meta-analysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, analyzing data from 15 studies selected from PubMed, Embase, Web of Science, and the Cochrane Library up to May 16, 2023. These studies were selected based on inclusion criteria such as study design, outcome of interest, exposure factor, and data extractability. Quality assessment was performed using the Newcastle-Ottawa Scale. We assessed the heterogeneity between studies and conducted a sensitivity analysis.

Results:
Data from 10,131 subjects, including 1304 diagnosed GDM cases, were analyzed. The meta-analysis showed that women in the low Vitamin C exposure group had higher odds of developing GDM (odds ratio 2.72, 95% CI:1.24–4.19). There was a greater likelihood of increased GDM risk with lower Vitamin C exposure (standardized mean difference: −0.71, 95% CI [−1.07 −0.36]). Subgroup analysis revealed that both internal and external Vitamin C exposure, along with exposure during the second or third trimester of pregnancy, was associated with higher GDM incidence rates under low Vitamin C exposure. Sensitivity analysis confirmed the robustness of the results, and no significant publication bias was detected.

Conclusion:
Low Vitamin C exposure during pregnancy may increase the risk of GDM. Given these findings, it could be beneficial for pregnant women to increase their intake of Vitamin C-rich foods and to ensure adequate blood Vitamin C levels as a preventive measure against GDM.
A comparison of effectiveness between Posisep and Merocel nasal packing after endoscopic sinus surgery: Findings from a randomized, double-blinded, controlled trial
Authors: Pham Huu Kien , Nguyen Trong , Tran Tai Thanh , Thai Truc Thanh 
Published: August 2023

Background:
The effectiveness of nonabsorbable and biodegradable nasal packing is still controversial, and the choice of nasal packing type can alter the outcome of endoscopic sinus surgery. This study compared the effectiveness of Posisep and Merocel as nasal packing materials with regard to hemostasis, adhesion, wound healing, patient’s satisfaction and health-related quality of life after endoscopic sinus surgery (ESS).

Methods:
A prospective, randomized, double-blinded, controlled trial was conducted in patients with chronic rhinosinusitis refractory undergoing symmetrical bilateral ESS. At the completion of surgery, a nasal packing (either Merocel or Posisep) was randomly chosen and placed into the middle meatus of each nasal cavity. All patients were scheduled for follow-up visits at 24 hours, 5 days, 3 weeks, and 5 weeks days after surgery. Health-related quality of life was measured using the Sino-Nasal Outcome Test (SNOT-22). The overall inflammatory burden of chronic rhinosinusitis was measured by the Lund-Mackay postoperative endoscopic score (LMES).

Results:
Among 62 patients included in data analysis (n = 31 for each group), the mean age was 42.4 years and 54.8% were females. Patients with Posisep after ESS had more improvement and better symptoms measured through SNOT-22 and LMES at 24 hours, 5 days, and 3 weeks than those with Merocel after ESS. While some aspects measured by LMES such as discharge and scarring were still better until 5 weeks after surgery, all symptoms measured by SNOT-22 were similar between the 2 groups 5 weeks after surgery.

Conclusion:
Posisep containing chitosan provided patients with a better quality of life throughout the early recovery period compared with Merocel. Although more studies are needed, our findings support the use of Posisep after ESS.
Can Enterococcus faecium prevent NEC in preterm infants?: A systematic review and meta-analysis
Authors: Men Guangguo , Wang Lili , Lu Xudan , Wen Gang , Lü Qin 
Published: August 2023

Objective:
Previous some systematic reviews reported that probiotics may benefit the prevention of NEC in preterm infants. But dissimilar bacterial strains and taxa used in included studies possibly result in bias. There is not a rounded systematic review which has estimated the benefit and safety of Enterococcus faecium to prevent NEC in preterm infants to date before we conducted.

Methods:
This systematic review of randomized controlled trials and retrospective studies analyzing the benefit of Enterococcus faecium to prevent NEC in preterm infants was performed using PubMed, Web of Science, Cochrane Library, EMBASE, Wanfang data and China National Knowledge Infrastructure databases from inception to April 14, 2023. The search terms were “preterm” AND “necrotizing enterocolitis” AND “Enterococcus faecium OR probiotics.” Studies reporting NEC involving preterm infants who were given Enterococcus faecium were included in this systematic review. A sensitivity analysis was conducted to assess the stability of results. A funnel plot was generated to identify publication bias. Two authors appraised studies quality and extracted data independently. This work has been reported according with preferred reporting items for systematic reviews and meta-analyses and assessing the methodological quality of systematic reviews. Statistical analysis was conducted using Review Manager 5.3 software. Risk ratio (RR) with 95% confidence intervals (CI) was calculated and analyzed.

Results:
Seven studies (N = 1487 participants) were included in this systematic review, and 6 randomized, controlled trials (N = 1237 participants) were included in the meta-analysis. Comparing with the control groups, the Enterococcus faecium groups had a significant decline in the incidence of NEC Bell stage II or higher (RR: 0.3138, 95% CI: 0.1983–0.4965; P < .00001; 6 studies, n = 1237) and infection (RR: 0.4818, 95% CI: 0.2950–0.7869; P = .004; 3 studies, n = 710).

Conclusions:
Enterococcus faecium is effective and safe in preventing NEC (Bell stage II or higher) in preterm infants. But all studies included came from China. The dosages and durations of taking Enterococcus faecium were various.
Feasibility, Outcomes, and Perceptions of a Virtual Group Exercise Program in Multiple Sclerosis
Authors: Garg Hina , Rutherfurd Charlotte , Labrum Jared , Hawley Bet , Gard Emily , Davis James 
Published: August 2023

Background and Purpose:
Individuals with multiple sclerosis (MS) frequently report low physical activity and psychosocial support due to concerns with transportation, time, finances, access to services, and lack of caregiver support. These barriers can be addressed by online group interventions; however, utility of such programs in individuals with MS has not been examined yet. The purpose of this retrospective study was, therefore, to (a) investigate the feasibility, safety, and outcomes of a virtual group exercise program in individuals with MS, and (b) explore the participant perceptions after the program.

Methods:
Retrospective data from the medical records of 17 individuals with MS (mean [SD] age = 53.5 [12.3] years, body mass index = 28.2 [7.2]) who completed the virtual 13-week group exercise program, pre- and posttraining functional status questionnaires, and the end-of-program feedback were extracted. The exercise program included aerobic, resistance, balance, and flexibility training components recommended for people with MS. Feasibility, safety, outcomes, and participant perceptions were determined by adherence to the prescribed daily exercise dosage, number of adverse events, within-group differences in self-reported functional status, and thematic analysis of the participant feedback, respectively.

Results:
Participants were adherent (79%), reported minimal adverse effects, and demonstrated significant changes (P < 0.05) in functional status posttraining. Several themes on the perceived barriers, facilitators, and suggestions for improvement were identified.

Discussion and Conclusions:
A virtual 13-week group exercise program can be feasible, safe, effective, and well received by individuals with MS. Future research should investigate the dose-response effectiveness of telehealth and compare various telehealth models of exercise training using large randomized controlled trials.
