Elevated citrulline and C5-OH levels are reported as part of the newborn screening of core and secondary disorders on the Recommended Uniform Screening Panel (RUSP). Additionally, some state laboratory newborn screening programs report low citrulline levels, which may be observed in proximal urea cycle disorders. We report six patients who were found on newborn screening to have low citrulline and/or elevated C5-OH levels in whom confirmatory testing showed the combination of these two abnormal analytes. Mitochondrial sequencing revealed known pathogenic variants in MT-ATP6 at high heteroplasmy levels in all cases. MT-ATP6 at these heteroplasmy levels is associated with Leigh syndrome, a progressive neurodegenerative disease. Patients were treated with supplemental citrulline and, in some cases, mitochondrial cofactor therapy. These six patients have not experienced metabolic crises or developmental regression, and early diagnosis and management may help prevent the neurological sequelae of Leigh syndrome. The affected mothers and siblings are asymptomatic or paucisymptomatic (e.g intellectual disability, depression, migraines, obsessive-compulsive disorder, and poor balance) despite high heteroplasmy or apparent homoplasmy of the familial variant, thus expanding the clinical spectrum seen in pathogenic variants of MT-ATP6. Confirmatory plasma amino acid analysis and acylcarnitine profiling should be ordered in a patient with either low citrulline and/or elevated C5-OH, as this combination appears specific for pathogenic variants in MT-ATP6.

In quantitative assays for hepatitis B virus (HBV) DNA, although the amplification reaction signal is detected for low-positive cases, quantification remains challenging. HBV reactivation has been reported in many studies, but only a few have focused on HBV low-positive cases. This study aimed to determine the reactivation rate and risk factors for HBV reactivation in low-positive cases.

In this retrospective cohort study, we analyzed 7498 patients who had their HBV DNA measured at Sapporo Medical University Hospital between April 2008 and November 2020. Patient selection criteria were defined as follows hepatitis B surface antigen was negative; HBV DNA was detectable but not quantifiable at least once. HBV DNA was monitored according to the guidelines for HBV reactivation.

In total, 49,086 HBV DNA quantitative tests were performed. HBV DNA levels of 2578 tests were detectable but not quantifiable. Eighty patients met the criteria in this study. The median observation period was 497 days, and the 2-year reactivation rate was 15%. Ten patients had low HBV DNA positivity at baseline. Malignant lymphoma was observed in 15 patients; chemotherapy was used to treat other solid tumors in 35 patients, and immunosuppressive therapy was used in 30 patients. Multivariate analysis revealed that HBV DNA detected below the quantification level at baseline was an independent risk factor for HBV reactivation (adjusted hazard ratio 5.82; P=0.010).

Patients with low HBV DNA positivity, especially at baseline, are at high risk for HBV reactivation and therefore require closer monitoring.

Several clinical studies have reported the efficacy of favipiravir in reducing viral load and shortening the duration of symptoms. However, the viability of SARS-CoV-2 in the context of favipiravir therapy and the potential for resistance development is unclear.

We sequenced SARS-CoV-2 in nasopharyngeal specimens collected from patients who participated in a randomized clinical trial of favipiravir at hospitals across Japan between March and May 2020. 3-MA clinical trial Paired genomes were sequenced from those who remained RT-PCR-positive 5-8 days into favipiravir therapy. Daily nasopharyngeal specimens from 69 patients who were RT-PCR-positive at randomization were examined for a cytopathic effect (CPE).

Some strains early in the trial belonged to clade 19B, whereas the majority belonged to clade 20B. The median time from the disease onset to negative CPE was 9 days. CPE was strongly correlated with the time from disease onset, viral load, age, and male sex. Among 23 patients for whom paired genomes were available, all except one had identical genomes. Two mutations were observed in one patient who received favipiravir, neither in the RdRp gene.

The SARS-CoV-2 genome distribution in this clinical trial conducted in Japan reflected the early influx of strains from China followed by replacement by strains from Europe. CPE was significantly associated with age, male sex, and viral loads but not with favipiravir therapy. There was no evidence of resistance development during favipiravir therapy.

The electronic search was carried out on Embase, PubMed, Cochrane Library, Web of Science, Scopus, LILACS, and grey literature up to March 22, 2020 (registration number INPLASY202030005). Only randomized controlled trials were included to answer the following PICOS question 'What grafting materials produce greater alveolar ridge preservation after tooth extraction?' The primary outcomes were the alveolar width resorption 1 mm below the alveolar crest and buccal height resorption in millimeters. Of the 4379 studies initially identified, 31 studies involving 1088 patients were included in the quantitative analyses. Out of 25 revised biomaterials, eight showed a statistically significant difference compared with unassisted healing in both alveolar width and height measurements (mean width differences ApatosⓇ, 2.27 [1.266-3.28]; Bio-OssⓇ, 0.88 [0.33-1.42]; Bio-Oss CollⓇ, 0.53 [0.04-1.01]; Bond-apatiteⓇ, 2.20 [1.30-3.11]; freeze-dried bone allograft, 1.35 [0.44-2.26]; Gen-OsⓇ, 1.90 [0.60-3.20]; platelet-rich fibrin, 1.66 [0.66-2.67]; and MP3Ⓡ, 2.67 [1.59-3.75]). link2 Overall, xenograft materials should be considered as among the best of the available grafting materials for alveolar preservation after tooth extraction.Evaluation of the surgical outcome and the patient satisfaction between the modified Wies technique and the Jones retractor plication technique for involutional lower eyelid entropion without horizontal eyelid laxity. Patients who underwent the modified Wies technique (group 1) and the Jones retractor plication technique (group 2) for correction of involutional lower eyelid entropion without horizontal eyelid laxity between January 2014 and January 2020 were retrospectively reviewed. Patients with horizontal eyelid laxity; cicatricial, congenital or iatrogenic entropion; and less than 6 months of follow-up time were excluded. The main outcome measures were the recurrence rate, correct anatomical position of the eyelid, symptom relief, and postoperative complications for both groups. 37 patients (41 eyes) in Group 1 and 34 patients (34 eyes) in Group 2 were enrolled in the study. Mean age ± SD was 75.6 ± 8.5 years in Group 1 and 73.4 ± 7.9 years in Group 2 (p0.255). The mean follow-up time (range) was 24.3 (6-80) months in group 1 and 25.3 (6-78) months in group 2 (p0.818). Two patients in Group 1 and seven patients in Group 2 had a recurrence during the follow-up period (p0.07). Based on the results of the study, it seems that the modified Wies technique may be a good alternative in suitable patients, as it has satisfactory surgical results.

Percutaneous ultrasonography (PUS) is used to evaluate the status of the spinal cord after cervical laminoplasty (CLP). This technique helps assess real-time movements of the spinal cord and provides immediate information regarding the decompression status. Additionally, it can also be utilized to evaluate the status of the spinal cord in various body positions and neck postures. This study aimed to examine changes in the decompression status of the spinal cord after CLP for cervical spondylotic myelopathy (CSM) in different body positions and neck postures using PUS and to assess whether these decompression statuses are related to clinical outcomes at each time point.

The study included 66 consecutive participants with CSM who underwent double-door CLP with suture anchors. PUS was performed postoperatively at 2 weeks, 3 months, 6 months, and 1 year in sitting [neck flexion (Flexion), neutral (Neutral), and extension (Extension)] and supine (Supine) positions. The decompression status was classified into ion of the anterior subarachnoid space in supine position may indicate positive clinical outcomes after CLP.

We assessed the efficacy and safety of total neoadjuvant therapy, including targeted agent plus FOLFOXIRI (5-fluorouracil, leucovorin, oxaliplatin and irinotecan) induction chemotherapy followed by intensified chemoradiotherapy (CRT) and surgical resection, in patients with locally advanced rectal cancer.

This was a single-arm, single-centre phase II trial. Eligible patients had non-metastatic locally advanced rectal adenocarcinoma. Based on Ras-BRAF status, patients were treated with bevacizumab (mutated Ras-BRAF) or panitumumab/cetuximab (wild-type Ras-BRAF) plus FOLFOXIRI regimen followed by oxaliplatin-5-fluorouracil-based CRT and surgery. The primary end point was pathological complete response rate. Secondary end points were toxicity, compliance, tumour downstaging, complete resection, surgical complications, local and distant failures and overall survival. The sample size was planned to expect an absolute 20% improvement in pathological complete response rate over historical literature data with ans targeted agent-based induction chemotherapy and intensified CRT before surgery showed promising clinical activity and was well tolerated in locally advanced rectal cancer patients. This phase II trial provides a strong rationale for phase III studies.

The type of fat consumed in animal-based western diets, typically rich in the saturated fat palmitate, has been implicated in cardiometabolic disease risk. In contrast, the most abundant mono- and polyunsaturated fats, more typical in a vegetarian or plant-based diet, potentiate less deleterious effects. link3 This study determined differences in plasma and urine metabolites when switching from omnivorous to vegetarian diet, including metabolites involved in fatty acid utilization.

A prospective cohort of 38 European (EA) and African American (AA) omnivorous females were matched by age (25.7±5.3y) and BMI (22.4±1.9kg/m

). Pre-intervention samples were collected while subjects consumed habitual animal-based diet. Changes in metabolites were assessed by ultra-high-performance liquid chromatography-tandem mass spectroscopy (Metabolon, Inc.) upon completing four days of novel vegetarian diet provided by the Vanderbilt Metabolic Kitchen. Changes in several diet-derived metabolites were observed, including increases in compounds derived from soy food metabolism along with decreases in metabolites of xanthine and histidine.
