Florigen-producing cells express FPF1-LIKE PROTEIN 1 that accelerates flowering and stem growth in long days with sunlight red/far-red ratio in Arabidopsis.

Seasonal changes in spring induce flowering by expressing the florigen, FLOWERING LOCUS T (FT), in Arabidopsis. FT is expressed in unique phloem companion cells with unknown characteristics. The question of which genes are co-expressed with FT and whether they have roles in flowering remains elusive. Through tissue-specific translatome analysis, we discovered that under long-day conditions with the natural sunlight red/far-red ratio, the FT-producing cells express a gene encoding FPF1-LIKE PROTEIN 1 (FLP1). The master FT regulator, CONSTANS (CO), controls FLP1 expression, suggesting FLP1's involvement in the photoperiod pathway. FLP1 promotes early flowering independently of FT, is active in the shoot apical meristem, and induces the expression of SEPALLATA 3 (SEP3), a key E-class homeotic gene. Unlike FT, FLP1 facilitates inflorescence stem elongation. Our cumulative evidence indicates that FLP1 may act as a mobile signal. Thus, FLP1 orchestrates floral initiation together with FT and promotes inflorescence stem elongation during reproductive transitions.

Factors influencing the reduction in quadriceps muscle thickness in the paretic limbs of patients with acute stroke.

BACKGROUND & AIMS: Muscle atrophy is an early event that occurs after stroke, but there are few reports on the changes in skeletal muscle thickness in acute stroke. This study investigated the factors contributing to reduced muscle thickness in patients with acute stroke. METHODS: In total, 51 patients with stroke and the National Institute of the Health Stroke Scale (NIHSS) > 3 were included in our study. They were admitted to our hospital between July 2017 and May 2020. The quadriceps muscle thickness was measured with an ultrasound device within 2 days after admission and 14 days later. The collected data included age, sex, body mass index, stroke type, neuromuscular electrical stimulation, NIHSS, serum albumin at admission, start of enteral nutrition, Functional Oral Intake Scale (FOIS), start of mobilization and ambulation, number of physical and occupational therapy units, C-reactive protein at admission and whether surgery had been performed. These data were retrospectively retrieved from medical documents. A dietician calculated energy intake, protein intake, and energy adequacy. Multiple regression analysis was used to identify the factors associated with reduced quadriceps muscle thickness. The independent variables were NIHSS, date of start of enteral feeding, protein intake, FOIS, date of mobilization, and date of start of ambulation training. RESULTS: The rate of change in quadriceps muscle thickness of the paretic limb was -15.3 % (interquartile range, -46.1-14.8 %). Multiple regression analysis showed that the factors responsible for the decrease in muscle thickness on the paretic side were FOIS (ß: 0.376; 95 % Cl, 0.999 to 4.541) and the start date of ambulation (ß: -0.378; 95 % Cl, -2.575 to -0.543), with a multiple correlation coefficient of 0.456. CONCLUSION: The FOIS and the start date of ambulation after acute stroke were related to the rate of reduction in muscle thickness on the paretic side.

Iron complexes supported by silyl-NHC chelate ligands: synthesis and use for double hydroboration of nitriles.

Iron complexes bearing new silyl-NHC bidentate ligands were synthesised by treating Fe3(CO)12 with a mixture of N-(hydrosilyl)methyl imidazolium salts and a base. These complexes showed high performance in the catalytic double hydroboration of nitrile with pinacolborane (HBpin) to produce N,N-bis(boryl)amine by a combination of UV irradiation and mild heating (60 °C). The product yields for the hydroboration of aromatic and aliphatic nitriles reached 85%-95% (NMR) using an iron complex (5 mol%). Reducing the loading amount of the iron complex to 0.5 mol% still afforded the products in high yields. An analogous ruthenium complex, which was similarly synthesised using Ru3(CO)12, showed lower activity. Stoichiometric reactions of the iron complex with nitriles afforded Fe(0)-N-silylimine complexes, which may be dormant states in nitrile hydroboration. A catalytic mechanism including Fe(0) N-silylimine species is proposed.

Multidirectional Traction Method Using SURGICEL NU-KNIT and Surgical Suture in Robot-assisted Laparoscopic Surgery for Endometrial Cancer.

OBJECTIVE: To describe a novel approach to robot-assisted laparoscopic total hysterectomy (RH) for endometrial cancer that minimizes cancer sell spillage and develops a stable surgical field. DESIGN: Demonstration of the multidirectional traction method with narrated video footage. SETTING: Many reports have indicated that RH for endometrial cancer has the same or superior short-term results compared with conventional laparoscopic hysterectomy (LH), and the long-term prognosis is the same [1,2]. However, there are no randomized controlled trials of RH versus LH, and some previous reports [3] have suggested that RH has a worse prognosis than LH, so the long-term prognosis should be considered with caution. Factors that may affect the long-term prognosis include the use of uterine manipulators [4] and compression of the uterine body with robotic forceps without tactile sensation [3]. However, to the best of our knowledge, no surgical technique capable of avoiding these factors has been established yet. Herein, we report a multidirectional traction method using SURGICEL NU-KNIT (Ethicon; Johnson & Johnson Medical Ltd., Tokyo, Japan), a local hemostatic agent, and surgical sutures. INTERVENTION: Cut 2-0 Prolene (Ethicon; Johnson & Johnson Medical Ltd., Tokyo, Japan) with straight needles (ST-70) thread to 35 cm, stick a 1 × 2 cm piece of SURGICEL NU-KNIT, and make knots Fig. 1. This implement is used to puncture the incisional margins of the peritoneum and then the abdominal wall to bring the thread to the surface of the body, where it is grasped with forceps and fixed. By repeating this operation, multidirectional traction can be obtained Fig. 2. A manipulating suture is also attached to the uterus to minimize the compression of the uterine body with robotic forceps. CONCLUSION: The multidirectional traction method allows for reproducible stable surgical field development and minimizes cancer cell spillage by reducing uterine grasping by robotic forceps without the use of uterine manipulators.

Association Between Mobilization Level And Activity of Daily Living Independence in Critically Ill Patients.

OBJECTIVE: To examine the association between the mobilization level during intensive care unit (ICU) admission and independence in activity of daily living (ADL), defined as Barthel Index (BI)≥70. METHODS: This was a post-hoc analysis of the EMPICS study involving nine hospitals. Consecutive patients who spend >48 hours in the ICU were eligible for inclusion. Mobilization was performed at each hospital according to the shared protocol and the highest ICU mobility score (IMS) during the ICU stay, baseline characteristics, and BI at hospital discharge. Multiple logistic regression analysis, adjusted for baseline characteristics, was used to deter-mine the association between the highest IMS (using the receiver operating characteristic [ROC]) and ADL. RESULTS: Of the 203 patients, 143 were assigned to the ADL independence group and 60 to the ADL dependence group. The highest IMS score was significantly higher in the ADL independence group than in the dependence group and was a predictor of ADL independence at hospital discharge (odds ratio, 1.22; 95% confidence interval, 1.07-1.38; adjusted p=0.002). The ROC cutoff value for the highest IMS was 6 (specificity, 0.67; sensitivity, 0.70; area under the curve, 0.69). CONCLUSION: These results indicate that, in patients who were in the ICU for more than 48 hours, that patients with good function in the ICU also exhibit good function upon discharge. However, prospective, multicenter trials are needed to confirm this conclusion.

Reliability and Effectiveness of the Japanese Version of the Mobilization Quantification Score.

Background The mobilization quantification score (MQS) provides an opportunity to quantify the duration and intensity of mobilization therapy in the intensive care unit (ICU) and predict functional outcomes in ICU patients after surgery and stroke. MQS is a numerical measurement of early mobilization dose in the ICU, and its relationship with activities of daily living (ADL) dependence has been shown. We created and validated the Japanese version of the MQS using the endpoint ADL in a mixed population of patients in the ICU. Materials and methods In this prospective study, consecutive patients who were admitted to one of three ICUs of a tertiary care hospital in Japan, aged ≥18 years, and who received mechanical ventilation for >48 hours were enrolled. The Japanese version of the MQS was applied twice daily by an ICU physiotherapist and data recorded for analysis. The primary outcome was ADL dependence at hospital discharge, defined as a Barthel index (BI) of <70 or in-hospital death. The reliability among assessors was verified by calculating the interclass correlation coefficient (ICC) (2.1) for the average daily MQS. We performed a multiple logistic regression analysis to examine and identify a binary cutoff point for high-/low-dose rehabilitation. Results Of the 340 target patients, eight were aged <18 years, 109 had neurological complications, 11 had a BI <70 before admission, 79 had a lack of communication skills, 16 were terminally ill, eight did not complete the assessment during their ICU stay, 18 died in the ICU, and 53 denied consent. After 302 patients were excluded, 38 were included in the study. Six assessors, two at each hospital, measured the MQS in 38 patients. The ICC (2.1) for the MQS mean value was 0.98 (0.96-0.99) during the ICU stay. Logistic regression analysis using the mean MQS on admission to ICUs as an explanatory variable showed a significant association between increased MQS and decreased ADL dependence at discharge (odds ratio (OR): 0.76, confidence interval (CI): 0.61-0.96, adjusted p = 0.009). Logistic regression analysis using a high MQS on admission to ICUs as an explanatory variable showed a significant association between increased MQS and decreased ADL dependence at hospital discharge (OR: 0.14, CI: 0.03-0.66, adjusted p = 0.013). Conclusions We present a validated version of the Japanese MQS with a high inter-rater reliability that predicts ADL dependence at hospital discharge. The instrument can be used in future clinical trials in the ICU to control for the mobilization level in the ICU. The increased utilization of mobilization acutely in the ICU setting as quantified by the MQS may improve patient outcomes.

Follow-up focused on psychological intervention initiated after intensive care unit in adult patients and informal caregivers: a systematic review and meta-analysis.

Psychological dysfunction is one of the considerable health-related outcomes among critically-ill patients and their informal caregivers. Follow-up of intensive care unit (ICU) survivors has been conducted in a variety of different ways, with different timing after discharge, targets of interest (physical, psychological, social) and measures used. Of diverse ICU follow-up, the effects of follow-ups which focused on psychological interventions are unknown. Our research question was whether follow-up with patients and their informal caregivers after ICU discharge improved mental health compared to usual care. We published a protocol for this systematic review and meta-analysis in https://www.protocols.io/ (https://dx.doi.org/10.17504/protocols.io.bvjwn4pe). We searched PubMed, Cochrane Library, EMBASE, CINAHL and PsycInfo from their inception to May 2022. We included randomized controlled trials for follow-ups after ICU discharge and focused on psychological intervention for critically ill adult patients and their informal caregivers. We synthesized primary outcomes, including depression, post-traumatic stress disorder (PTSD), and adverse events using the random-effects method. We used the Grading of Recommendations Assessment, Development and Evaluation approach to rate the certainty of evidence. From the 10,471 records, we identified 13 studies (n = 3, 366) focusing on patients and four (n = 538) focusing on informal caregivers. ICU follow-up for patients resulted in little to no difference in the prevalence of depression (RR 0.89, 95% CI [0.59-1.34]; low-certainty evidence) and PTSD (RR 0.84, 95% CI [0.55-1.30]; low-certainty evidence) among patients; however, it increased the prevalence of depression (RR 1.58 95% CI [1.01-2.46]; very low-certainty evidence), PTSD (RR 1.36, 95% CI [0.91-2.03]; very low-certainty evidence) among informal caregivers. The evidence for the effect of ICU follow-up on adverse events among patients was insufficient. Eligible studies for informal caregivers did not define any adverse event. The effect of follow-ups after ICU discharge that focused on psychological intervention should be uncertain.

Short tandem repeat polymorphism analysis for primary peritoneal choriocarcinoma: A case report and literature review.

The peritoneum is an extremely rare site for primary choriocarcinoma development. Primary peritoneal choriocarcinoma could be either gestational or nongestational, whereas it is straightforward to ascribe uterine or tubal choriocarcinoma to the gestational origin. Herein, we report a case of primary peritoneal choriocarcinoma that is genetically diagnosed as a gestational subtype originating from an occult complete hydatidiform mole. A 46-year-old female patient with two-time induced abortion histories underwent emergency laparotomy under clinical suspicion of ruptured tubal pregnancy. Laparotomy revealed a hemorrhagic tumor in the left mesosalpinx with apparently intact left ovary and fallopian tube. The excised tumor was pathologically diagnosed as choriocarcinoma. Multiplex short tandem repeat polymorphism analysis revealed an androgenetic/homozygous genotype tumor, identifying its origin as a complete hydatidiform mole. Our literature review of nine primary peritoneal choriocarcinoma cases, including ours, highlighted the importance of tumor genotyping in differentiating between gestational and non-gestational subtypes and identifying the causative pregnancy.

Ambulation status at an acute care hospital predicts pneumonia and mortality in stroke patients: A retrospective cohort study.

AIM: Higher post-stroke functional performance is associated with lower mortality in patients with stroke. This study aimed to investigate the relationship between ambulation ability in the acute phase of stroke, and pneumonia and mortality 1 year after stroke onset. METHODS: This retrospective cohort study included consecutive stroke patients between April 2008 and December 2018. Patients were divided into six groups according to their Functional Ambulation Category score at discharge (0 [unable to walk] to 5 [able to walk independently]). We observed pneumonia cases and all-cause mortality over 1 year, and investigated the association between Functional Ambulation Category score and pneumonia or mortality. Survival analysis was carried out using Kaplan-Meier curves, log-rank tests and Cox regression models. RESULTS: We analyzed 1727 consecutive patients (median age 77 years; 54% men). During the observation period, 144 patients (8.3%) experienced pneumonia and 157 (9.1%) died. Increasing ambulatory impairment showed stepwise relationships with the risk of pneumonia and mortality. Compared with patients with a Functional Ambulation Category score of 5, those with scores of 4 and 3 showed no significant association with pneumonia risk; a score ≤2 was significantly different. There was a stepwise relationship between increased gait disturbance and risk of death compared with the Functional Ambulation Category 5 group. CONCLUSIONS: Ambulation ability at discharge from an acute hospital is an important predictor of pneumonia incidence and survival in stroke patients at 1 year; these associations were observed even after controlling for clinical parameters, such as stroke severity and comorbidity.

Telerehabilitation in Subjects With Respiratory Disease: A Scoping Review.

Considering the current coronavirus disease (COVID-19) pandemic, telerehabilitation may be a viable first-line option for patients with respiratory tract disease. To date, there has been no systematic review on telerehabilitation for respiratory tract diseases, including COVID-19. Therefore, this scoping review aimed to determine what telerehabilitation for patients with respiratory tract diseases consists of, how safe telerehabilitation is for patients with respiratory tract diseases, and how feasible telerehabilitation is for hospitalized patients with COVID-19. In May 2020, we conducted a search of the following publication databases on the use of telerehabilitation in the treatment of respiratory tract diseases: Medical Literature Analysis and Retrieval System Online, Embase, Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Literature, and Physiotherapy Evidence Database. Of the 208 articles identified, 23 studies were subsequently included in this scoping review. In 22 of the included studies, subjects had stable COPD and underwent telerehabilitation at home. The final included study was a case series of subjects with severe acute respiratory syndrome coronavirus 2 infection who underwent telerehabilitation in-hospital. Most telerehabilitation programs consisted of aerobic exercises using a cycle ergometer or a treadmill, walking, and muscle-strengthening exercises. The reported number of adverse events was low, and most studies reported that the average session adherence rate was > 70%. The majority of the telerehabilitation programs included a face-to-face rehabilitation assessment. Our findings indicate that, in its current state, telerehabilitation may be safe and feasible and may lead to reduced face-to-face rehabilitation therapy; in addition, remote rehabilitation assessment should be considered during the COVID-19 pandemic. Further research that targets a more diverse range of respiratory tract diseases and considers telerehabilitation in a hospital setting is required.

Predictive Validity of the Scale for the Assessment and Rating of Ataxia for Medium-Term Functional Status in Acute Ataxic Stroke.

OBJECTIVES: This study examines the prognostic validity of the Scale for the Assessment and Rating of Ataxia for patients with acute stroke. MATERIALS AND METHODS: We enrolled 120 patients with posterior circulation stroke having ischemic or hemorrhagic lesions with ataxia who had physical therapy. We recorded the clinical stroke features and obtained the scale for the assessment and rating of ataxia and National Institutes of Health Stroke Scale scores 7 days after admission and at discharge. Predictive factors for a 3-month modified Rankin Scale score of <3 were investigated. RESULTS: During hospitalization, the Scale for the Assessment and Rating of Ataxia score decreased from 7.5 (interquartile range, 4.5-12.5) to 4.0 (interquartile range, 1.5-8.0) points, whereas the National Institutes of Health Stroke Scale score changed from 1 (interquartile range, 0-3) to 1 (interquartile range, 0-2) point. A significant correlation between functional outcome and the Scale for the Assessment and Rating of Ataxia scores 7 days after onset was observed. The cutoff value for the assessment and rating of ataxia for predicting favorable outcome (modified Rankin scale, 0-2) at 3 months post-onset was 14 points (0-40) at 7 days after onset. CONCLUSIONS: The Scale for the Assessment and Rating of Ataxia scores showed good responsiveness to neurological changes in patients with acute ataxic stroke, could predict functional outcomes 3 months after onset on day 7, and could be a useful and reliable marker for patients with ataxic stroke.

Short-Physical Performance Battery (SPPB) score is associated with postoperative pulmonary complications in elderly patients undergoing lung resection surgery: A prospective multicenter cohort study.

Elderly patients awaiting lung resection surgery often have poor physical function, which puts them at a high risk of postoperative pulmonary complications. The aim of this study was to investigate the impact of preoperative physical performance on postoperative pulmonary complications in patients awaiting lung resection surgery. In this prospective multicenter cohort study, the characteristics of patients and postoperative pulmonary complications were compared between subjects with low (<10) and high (≥10) Short Physical Performance Battery (SPPB) scores. Postoperative pulmonary complications were defined as over grade II in Clavien-Dindo classification system. We estimated the effects of physical performance on postoperative pulmonary complications using multivariable hierarchical logistic regression. The postoperative pulmonary complications were compared between 331 patients in the high and 33 patients in the low SPPB group. Patients in the low SPPB score group had a significantly higher rate of postoperative pulmonary complications (p < 0.001). Low SPPB score was associated with a higher risk of postoperative pulmonary complications (odds ratio, 8.80; p < 0.001). The SPPB is a clinically useful evaluation tool to assess surgical patients' physical performance. The low physical performance indicated by the SPPB may be predictive of postoperative pulmonary complications after lung resection surgery.Trial registration: Clinical Trials.

Does enhanced physical rehabilitation following intensive care unit discharge improve outcomes in patients who received mechanical ventilation? A systematic review and meta-analysis.

OBJECTIVE: We aimed to determine whether enhanced physical rehabilitation following intensive care unit (ICU) discharge improves activities-of-daily-living function, quality of life (QOL) and mortality among patients who received mechanical ventilation in the ICU. DESIGN: Systematic review and meta-analysis using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. DATA SOURCES: MEDLINE, Embase, CENTRAL, PEDro and WHO International Clinical Trials Registry Platform searched through January 2019. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: We included randomised controlled trials assessing the effect of post-ICU rehabilitation designed to either commence earlier and/or be more intensive than the protocol employed in the control group. Only adults who received mechanical ventilation for >24 hours were included. DATA EXTRACTION AND SYNTHESIS: Two independent reviewers extracted data and assessed risk of bias. Standard mean differences (SMDs) with 95% CIs were calculated for QOL, and pooled risk ratios (RRs) with 95% CIs are provided for mortality. We assessed heterogeneity based on I² and the certainty of evidence based on the GRADE approach. RESULTS: Ten trials (enrolling 1110 patients) compared physical rehabilitation with usual care or no intervention after ICU discharge. Regarding QOL, the SMD (95% CI) between the intervention and control groups for the physical and mental component summary scores was 0.06 (-0.12 to 0.24) and -0.04 (-0.20 to 0.11), respectively. Rehabilitation did not significantly decrease long-term mortality (RR 1.05, 95% CI 0.66 to 1.66). The analysed trials did not report activities-of-daily-living data. The certainty of the evidence for QOL and mortality was moderate. CONCLUSIONS: Enhanced physical rehabilitation following ICU discharge may make little or no difference to QOL or mortality among patients who received mechanical ventilation in the ICU. Given the wide CIs, further studies are needed to confirm the efficacy of intensive post-ICU rehabilitation in selected populations. PROSPERO REGISTRATION NUMBER: CRD42017080532.
