ABSTRACT
BACKGROUND & AIMS: Sarcopenia, characterized by loss of muscle mass and decreased muscle strength, significantly affects adults but also influences pediatric health. However, definitions for low muscle mass, decreased strength, and sarcopenia in children are less established, impacting interventions for improving health outcomes. The objective of this scoping review is synthesize the existing literature on the diagnostic criteria, prevalence and clinical outcomes of sarcopenia. METHODS: A scoping review, following the PRISMA extension for scoping reviews, examined pediatric sarcopenia literature until June 2023. The literature search was performed using MEDLINE and the Cochrane Central Register of Controlled Trials with the last search conducted on June 30, 2023. Criteria included studies on aged 0-20 years, covering healthy subjects, acutely ill patients, and chronic disease cases excluding specific conditions like neuromuscular diseases or prematurity. RESULTS: Initial search found 503 studies, finally, we included 56 studies. Most studies diagnosed sarcopenia using skeletal muscle mass indicators like total psoas muscle area from Computed Tomography or Magnetic Resonance Imaging. Around half of the longitudinal studies highlighted sarcopenia as a risk factor for various clinical outcomes, predominantly in hospitalized patients. However, cutoff values for sarcopenia indicators lacked consistency, with studies employing diverse percentile-based measurements or z-scores. CONCLUSION: Pediatric sarcopenia diagnosis primarily relies on skeletal muscle mass, with identified links to future clinical outcomes in specific conditions. The lack of standardized cutoffs for sarcopenia indicators underscores the necessity for age, gender, and race-specific cutoff values derived from studies establishing reference values for muscle mass and strength across diverse pediatric populations.

Psychological aspects of rehabilitation nutrition affect physical, cognitive, and social rehabilitation nutrition. When depression is recognized, not only pharmacotherapy and psychotherapy, but also non-pharmacological therapies such as exercise, nutrition, psychosocial, and other interventions can be expected to improve depression. Therefore, accurate diagnosis and intervention without overlooking depression is important. Psychological aspects of preventive rehabilitation nutrition is also important because depression can be partially prevented by appropriate exercise and nutritional management. Even in the absence of psychological negatives, increasing more psychological positives from a positive psychology perspective can be useful for both patients and healthcare professionals. Positive rehabilitation nutrition interventions can increase more psychological positives, such as well-being, through cognitive-behavioral therapy and mindfulness on their own, as well as through interventions on environmental factors. Consequently, physical, cognitive, and social positives are also expected to be enhanced.
ABSTRACT
OBJECTIVE: Narrow-band imaging (NBI) is considered useful for detecting respiratory papillomatosis. However, the choice between preoperative and intraoperative NBI depends on the facility. We investigated the usefulness of NBI and determined whether preoperative NBI can replace intraoperative NBI with a comparable detection rate. METHODS: In this retrospective cohort study conducted at single a tertiary care center, patients with respiratory papillomatosis treated between 2017 and 2022 were enrolled. We systematically compared preoperative white light imaging (WLI) with preoperative and intraoperative NBI. The primary endpoints were the papilloma detection rate and lesion site assessed by the Derkay scoring system. The secondary endpoints were the risk factors for increased Derkay scores. RESULTS: The study included 127 patients with papilloma. Intraoperative NBI yielded significantly higher Derkay scores than preoperative WLI (p < 0.001) and preoperative NBI (p = 0.004). The papilloma detection rates of preoperative WLI and preoperative NBI were not significantly different. Intraoperative NBI detected more lesions than preoperative NBI in 37 of 127 (29%) patients; the overall number of additional lesions was 47 of 279 (17%). Compared with preoperative NBI, intraoperative NBI yielded significantly higher scores for the vocal cords (p = 0.005), false vocal cords (p = 0.010), and ventricle of the larynx (p < 0.001). Elevated Derkay scores were significantly associated with male sex (p = 0.012) and alcohol consumption (p = 0.007). CONCLUSION: Intraoperative NBI is more accurate in detecting papillomatous lesions, and preoperative NBI cannot replace intraoperative NBI. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:1820-1824, 2024.

Purpose: Sleep-tracking devices have performed well in recent studies that evaluated their use in healthy adults by comparing them with the gold standard sleep assessment technique, polysomnography (PSG). These devices have not been validated for use in patients with psychiatric disorders. Therefore, we tested the performance of three sleep-tracking devices against PSG in patients with psychiatric disorders. Patients and methods: In total, 52 patients (32 women; 48.1 ± 17.2 years, mean ± SD; 18 patients diagnosed with schizophrenia, 19 with depressive disorder, 3 with bipolar disorder, and 12 with sleep disorder cases) were tested in a sleep laboratory with PSG, along with portable electroencephalography (EEG) device (Sleepgraph), actigraphy (MTN-220/221) and consumer sleep-tracking device (Fitbit Sense). Results: Epoch-by-epoch sensitivity (for sleep) and specificity (for wake), respectively, were as follows: Sleepgraph (0.95, 0.76), Fitbit Sense (0.95, 0.45) and MTN-220/221 (0.93, 0.40). Portable EEG (Sleepgraph) had the best sleep stage-tracking performance. Sleep-wake summary metrics demonstrated lower performance on poor sleep (ice, shorter total sleep time, lower sleep efficiency, longer sleep latency, longer wake after sleep onset). Conclusion: Devices demonstrated similar sleep-wake detecting performance as compared with previous studies that evaluated sleep in healthy adults. Consumer sleep device may exhibit poor sleep stage-tracking performance in patients with psychiatric disorders due to factors that affect the sleep determination algorithm, such as changes in autonomic nervous system activity. However, Sleepgraph, a portable EEG device, demonstrated higher performance in mental disorders than the Fitbit Sense and actigraphy.
ABSTRACT
We defined respiratory sarcopenia as a coexistence of respiratory muscle weakness and decreased respiratory muscle mass. Although respiratory muscle function is indispensable for life support, its evaluation has not been included in the regular assessment of respiratory function or adequately evaluated in clinical practice. Considering this situation, we prepared a position paper outlining basic knowledge, diagnostic and assessment methods, mechanisms, involvement in respiratory diseases, intervention and treatment methods, and future perspectives on respiratory sarcopenia, and summarized the current consensus on respiratory sarcopenia. Respiratory sarcopenia is diagnosed when respiratory muscle weakness and decreased respiratory muscle mass are observed. If respiratory muscle mass is difficult to measure, we can use appendicular skeletal muscle mass as a surrogate. Probable respiratory sarcopenia is defined when respiratory muscle weakness and decreased appendicular skeletal muscle mass are observed. If only respiratory muscle strength is decreased without a decrease in respiratory function, the patient is diagnosed with possible respiratory sarcopenia. Respiratory muscle strength is assessed using maximum inspiratory pressure and maximum expiratory pressure. Ultrasonography and computed tomography are commonly used to assess respiratory muscle mass; however, there are insufficient data to propose the cutoff values for defining decreased respiratory muscle mass.

OBJECTIVE: Clozapine may cause serious side effects despite benefits in patients with schizophrenia. Thus, an accurate understanding of the side-effect profile of clozapine is extremely important in the management of its administration to patients with schizophrenia. Our aim was to validate the relationship between clozapine exposure and appendicitis onset in patients with schizophrenia. METHODS: In this study, we retrospectively compared the incidence and cumulative incidence of appendicitis in patients with schizophrenia with and without a history of clozapine exposure. Among the patients with schizophrenia who visited our hospital between June 2009 and August 2021, we extracted those with a history of clozapine treatment. Patients with a history of taking clozapine were defined as the clozapine exposure group, while the others were defined as the clozapine non-exposure group. Patients with a history of appendectomy before their initial visit to our hospital or with a history of clozapine use at other hospitals were excluded. RESULTS: There were 65 patients in the clozapine exposure group and 400 patients in the clozapine non-exposure group who met the inclusion criteria. The exposure group exhibited a remarkably higher incidence of appendicitis during the observation period than the non-exposure group (863 cases vs. 124 cases per 100,000 person-years). In particular, if limited to the period of clozapine exposure, the incidence of appendicitis is extremely high, at 2,086 cases per 100,000 person-years. Moreover, multivariable analysis showed that clozapine exposure was an independent factor contributing to the onset of appendicitis. CONCLUSIONS: Clozapine exposure is associated with appendicitis onset in patients with schizophrenia.

Diagnostic reasoning is the thought process used to arrive at a diagnosis based on symptoms, examination findings, and laboratory values. Diagnosis is categorized as nonanalytic reasoning (intuition) and analytic reasoning (analysis). Rehabilitation nutrition involves the diagnosis of nutritional disorders, sarcopenia, and excess or deficient nutrient intake. There is usually only one correct answer for the presence or absence of these. On the other hand, there may be no single correct answer for the causes of anorexia, weight loss, or sarcopenia, and analytical reasoning is required. In this case, diagnostic reasoning involves hypotheses. Simply using nutritional supplements without performing diagnostic reasoning about these causes is like prescribing antipyretic analgesics to a patient with a headache without diagnosing the cause of the headache. To maximize function and quality of life in rehabilitation nutrition, it is necessary to suspect the common causes of anorexia, weight loss, and sarcopenia in all cases.

The most important nutrition goals in rehabilitation nutrition are improving function and quality of life, and they are useful to set body weight goals to further improve these aspects. In this paper, we clarified our position, as the Japanese Association of Rehabilitation Nutrition, on body weight goal setting. Body weight goals should be SMART (Specific, Measurable, Achievable, Realistic/Relevant, and Timed). The standard amount of energy accumulation/deficit needed to gain/lose 1 kg body weight is 7500 kcal. In other words, if the nutrition goal is set at 1 kg body weight gain per month, daily energy accumulation can be calculated as approximately 250 kcal. It is necessary to reconcile the rehabilitation goal setting, the content, quantity, and quality of physical activity and exercise therapy, and the patient's general condition and intentions to set nutrition goals. Body weight goal setting is more variable than rehabilitation goal setting, and it is important to confirm the degree of achievement through rehabilitation nutrition monitoring.
ABSTRACT
PURPOSE: A major depressive episode is a risk factor for venous thromboembolism (VTE) in psychiatric inpatients. However, it is unclear whether the severity of depressive symptoms or duration of the current depressive episode is associated with VTE. Further, the VTE prevalence among hospitalized patients with a major depressive episode receiving electroconvulsive therapy is unknown. This retrospective study examined factors associated with VTE among hospitalized patients with a major depressive episode and estimated the prevalence of VTE in such patients who underwent electroconvulsive therapy. PATIENTS AND METHODS: Patients with a major depressive episode hospitalized in the Department of Neuropsychiatry at Akita University Hospital between January 2018 and December 2020 were included. Data from the first week of hospitalization were extracted from medical records. VTE was diagnosed based on the findings of computed tomography. To evaluate whether the severity of depressive symptoms or duration of the current depressive episode was associated with VTE, logistic regression analysis was conducted after adjusting for covariates with known VTE risk factors (antidepressants, antipsychotics, and physical comorbidities). RESULTS: We analyzed 133 patients; of these, 14 were diagnosed with asymptomatic VTE. The severity of depressive symptoms (odds ratio: 1.220, 95% confidence interval: 1.081-1.377, p = 0.001) was significantly associated with VTE. The prevalence of VTE among those receiving electroconvulsive therapy was 35% (7/20). CONCLUSION: The prevalence of VTE was 35% among patients receiving in-hospital electroconvulsive therapy for a major depressive episode. VTE should be considered for hospitalized patients with severe depressive symptoms and patients receiving in-hospital electroconvulsive therapy for a major depressive episode.
ABSTRACT
BACKGROUND: Individuals undergoing rehabilitation often experience nutritional problems such as malnutrition, but there are no clinical practice guidelines (CPGs) specifically tailored to the combination of rehabilitation and nutritional care for these patients. The Japanese Association for Rehabilitation Nutrition aimed to develop CPGs for rehabilitation nutrition to support clinical decision making in daily practice. METHODS: A CPG committee and development process based on the Grading of Recommendations Assessment, Development and Evaluation system and the Minds Handbook for Clinical Practice Guideline Development 2014 was established. Four clinical questions were defined for patients undergoing rehabilitation for cerebrovascular disease, hip fracture, cancer, and acute illness. Literatures of randomised control trials (RCTs) up to April 2020 were searched for using the MEDLINE, EMBASE, CENTRAL, and Ichushi-web databases. After screening, full-text papers were assessed for eligibility for analysis. Subsequently, studies included in the systematic review were examined regarding their risk of bias, and underwent meta-analyses. A CPG development committee drafted the guidelines based on the systematic review report. Final recommendations were determined by the panel members. RESULTS: Four recommendations were made based on 4 to 9 RCTs for each disease/condition. The certainty of the evidence ranged from very low to low. Overall, the enhanced nutritional care was weakly recommended for rehabilitation patients with cerebrovascular disease, hip fracture, cancer, and acute illnesses. CONCLUSIONS: This CPG provides tentative recommendations for nutritional care of individuals undergoing rehabilitation. Due to low certainty of evidence and small sample sizes of the included studies, more high-quality and larger RCTs are needed to develop more practical CPGs.

PURPOSE: D-dimer has the advantage of excluding venous thromboembolism (VTE) due to its high sensitivity but is disadvantageous for diagnosing VTE due to its low specificity. A method to increase the usefulness of D-dimer in the diagnosis of VTE is warranted. This study aimed to investigate the usefulness of the combination of D-dimer and soluble fibrin monomer complex (SFMC), which has been suggested as a new candidate marker for VTE, in VTE diagnosis. PATIENTS AND METHODS: This prospective study in 109 subjects was performed at a psychiatric department between August 1, 2017 and December 31, 2019. Subjects' levels of D-dimer and SFMC were measured simultaneously. Plasma levels of D-dimer and SFMC were measured using NANOPIA® D-dimer and NANOPIA® SF. Subjects with positive D-dimer (≥1.0 µg/mL) results underwent contrast computed tomography for confirmation of VTE within 12 hours of D-dimer measurement. A receiver operating characteristic curve analysis was performed to examine the usefulness of SFMC for the diagnosis of VTE. RESULTS: Only 109 of the 783 subjects without symptoms suggestive of VTE participated in the study. Out of 41 subjects with positive D-dimer results, 17 subjects were diagnosed with VTE. A receiver operating characteristic curve analysis was performed to determine cutoff values. The area under the curves was 0.848 for SFMC (p<0.001, 95% CI 0.722 to 0.974), and the optimal cutoff value was 10.0 µg/mL (sensitivity 58.8%, specificity 100%, positive predictive value 100%, negative predictive value 77.4%). CONCLUSION: SFMC was useful for diagnosing VTE in the psychiatric patients with positive D-dimer results.

Dynamics of the photogenerated charge-separated (CS) state is studied for a newly synthesized molecular triad, in which the donor (D) dimethoxytriphenylamine, 1,3-bis(2-pyridylimino)isoindolate platinum (BPIPt), and the acceptor (A) naphthaldiimide are linked with a triethynylbenzene unit (BPIPt-DA). Photoexcitation of BPIPt gives rise to generation of a long-lived (â¼4 µs) CS state BPIPt-D+A-, of which the lifetime is considerably increased by an applied magnetic field of 270 mT. The positive magnetic field effect (MFE) is in contrast to the negative MFE for the reference DA molecule, which indicates successful switching of the initial spin state of the CS state from singlet to triplet. Simulations of the MFE and time-resolved electron paramagnetic resonance show that spin-selective charge recombination and spin relaxation are unaffected by attachment of BPIPt. The minimum impact of heavy atom substitution on the electronic and magnetic properties has been realized by the small electronic coupling mediated by the rigid meta-triethynylbenzene.
