Comparative analysis of humoral responses to BNT162b2 vaccine among patients with hematologic disorders and organ transplant recipients.

Vaccination against SARS-COV-2 is considered the most promising approach to curbing the pandemic. Patients with an immunocompromised state, such as those with hematological malignancies and organ transplantation recipients, are considered more susceptible to infection, but these at-risk patients were underrepresented in early clinical trials for vaccination. Although a growing body of studies suggests that the humoral response to COVID-19 vaccination in each of these at-risk groups of patients may be suboptimal in comparison to healthy controls, a clinical and strategic information for the further comparative analysis among these groups is not fully described.

Like a Rolling Stone: Year-Over-Year Growth of a Rectal Fecalith.

The inability to pass stool for a prolonged period can lead to the formation of fecaliths, which occurs most often in the colon or rectum. Although large fecaliths can lead to serious or life-threatening complications, the detailed process of their formation is unknown. This report describes a 65-year-old woman who presented with melena due to ischemic proctitis caused by a large fecalith.

Impact of body fat, body water content, and skeletal muscle mass index on peak salivary lactate levels after squat jump exercise in healthy non-athlete adult males.

Background: In the rehabilitation and sports science fields, comprehensive assessment of the response to exercise is important for accurately prescribing exercise programs. Lactate is an important energy substrate that is frequently measured in clinical practice because it provides information on aerobic capacity. Salivary lactate, which can be measured non-invasively, has recently been focused on as an alternative to blood lactate.

Tranilast for advanced heart failure in patients with muscular dystrophy: a single-arm, open-label, multicenter study.

Background: The transient receptor potential cation channel subfamily V member 2 (TRPV2) is a stretch-sensitive calcium channel. TRPV2 overexpression in the sarcolemma of skeletal and cardiac myocytes causes calcium influx into the cytoplasm, which triggers myocyte degeneration. In animal models of cardiomyopathy and muscular dystrophy (MD), TRPV2 inhibition was effective against heart failure and motor function.

Intranuclear inclusions in skin biopsies are not limited to neuronal intranuclear inclusion disease but can also be seen in oculopharyngodistal myopathy.

Aims: Oculopharyngodistal myopathy (OPDM) is caused by the expansion of CGG repeats in NOTCH2NLC (OPDM_NOTCH2NLC) GIPC1 (OPDM_GIPC1), or LRP12 (OPDM_LRP12). Neuronal intranuclear inclusion disease (NIID) is clinically distinct from OPDM but is also caused by the expansion of CGG repeats in NOTCH2NLC, which may be an indicator of intranuclear inclusion in skin biopsy. We investigated the presence of intranuclear inclusions in skin biopsies from patients with OPDM and muscle diseases with a similar pathology to evaluate whether they will have similar diagnostic findings on skin biopsy.

Reversible cerebral vasoconstriction syndrome with cardiac involvement during treatment for iron deficiency anemia: caser report.

Background: The diagnosis and therapy of reversible cerebral vasoconstriction syndrome (RCVS) tends to focus on neurological symptoms, but less attention has been paid the occurrence of extracerebral lesion such as the myocardium.

Case Presentation: A 40-year-old woman taking iron supplements for iron deficiency anemia due to menorrhagia had suffered from a thunderclap headache and seizure. Brain magnetic resonance imaging revealed high-intensity lesions bilaterally in the cerebellar and cerebral hemispheres.

Perforated Duodenal Diverticulum With Postoperative Diverticulum Bleeding Successfully Treated Using Transcatheter Arterial Embolization.

A diverticulum is a relatively common finding that is generally discovered incidentally; it is most commonly observed in the colon, followed by the duodenum. However, duodenal diverticulum perforation (DDP) is a rare complication. Due to its rarity, its diagnosis is often challenging and the appropriate treatment remains unclear, possibly contributing to its high mortality rate.

Elderly-Onset Multiple System Atrophy with Lewy Body Pathology: A Case Report.

An 81-year-old woman presented with a 2-year history of progressive dysarthria and gait disturbance. Subsequently, she developed orthostatic hypotension, obstructive sleep apnea, right-sided resting tremor, and rigidity. Together with characteristic findings of imaging studies, she was diagnosed with multiple system atrophy (MSA).

Increased carbohydrate antigen 19-9 expression in a thymic neuroendocrine tumor.

Here, we report a case of carbohydrate antigen (CA) 19-9-producing mediastinal neuroendocrine tumor (NET) (atypical carcinoid). A 54-year-old woman with no specific relevant medical history was referred to our hospital because of increased CA19-9 (95.3 U/ml) detected on health screening.

Disseminated Carcinomatosis of Bone Marrow as the Initial Presentation of Intrahepatic Cholangiocarcinoma without Jaundice: An Autopsy Case Report.

Disseminated carcinomatosis of the bone marrow (DCBM) is often accompanied by disseminated intravascular coagulation (DIC) and has a poor prognosis. DCBM develops most frequently in gastric cancer and is rarely associated with intrahepatic cholangiocarcinoma. A 41-year-old man was incidentally found to have DIC on his regular visit for ulcerative colitis and was diagnosed with DCBM with intrahepatic cholangiocarcinoma.

A web-based questionnaire survey on the influence of coronavirus disease-19 on the care of patients with muscular dystrophy.

To clarify the influence of coronavirus disease-19 (COVID-19) on the care of muscular dystrophy patients, we performed a questionnaire survey that was posted on the internet on May 11, 2020. By the end of July 2020, 542 responses had been collected. Approximately 30% of patients postponed regular consultations, and one-quarter of patients who received consultation more than once a month used telephone consultations.

aMAP score prediction of hepatocellular carcinoma occurrence and incidence-free rate after a sustained virologic response in chronic hepatitis C.

Aims: Hepatocellular carcinoma (HCC) can still occur in hepatitis C virus (HCV) patients who have achieved a sustained virologic response (SVR), which remains an important clinical issue in the direct-acting antivirals era. The current study investigated the clinical utility of the aMAP score (consisting of age, male, albumin-bilirubin, and platelets) for predicting HCC occurrence in HCV patients achieving an SVR by direct-acting antivirals.

Methods: A total of 1113 HCV patients without HCC history, all of whom achieved an SVR, were enrolled for clinical comparisons.

Changes in motor function in Duchenne muscular dystrophy patients after travel restrictions due to COVID-19.

Convergent validity of a simplified device and relationship between blood lactate and salivary lactate after a vertical squat jump in healthy non-athletes.

[Purpose] The aims of this study were 1) to examine the convergent validity between Lactate pro 2 and a standard JCA-BM 8000 automatic analyzer using salivary lactate and 2) to investigate the relationship between blood and salivary lactate levels after a vertical squat jump. [Participants and Methods] Healthy non-athletes participated in this observational study. The participants performed a vertical squat jump for 1 min 30 s.

Contamination of lenalidomide on blister packages after administration and its exposure countermeasures.

Background: Reliable exposure control measures are needed to avoid occupational exposures from hazardous drugs. However, there is little information on blister packages concerning exposure. We investigated the contamination and exposure control methods of lenalidomide.

Distal femoral impaction bone grafting in revision for tumor endoprosthesis.

Background: Reconstruction using tumor endoprosthesis has been widely used in cases with large bone defects caused by bone and soft tissue tumor resection of the distal femur which extend into the knee joint. However, reconstruction failure can lead to major problems in the long term. We have been performing impaction bone grafting with allogeneic cancellous bone during revision surgery for tumor endoprosthesis of the distal femur to compensate for the thinness and fragility of the remaining femur.

CGG expansion in NOTCH2NLC is associated with oculopharyngodistal myopathy with neurological manifestations.

Oculopharyngodistal myopathy (OPDM) is a rare hereditary muscle disease characterized by progressive distal limb weakness, ptosis, ophthalmoplegia, bulbar muscle weakness and rimmed vacuoles on muscle biopsy. Recently, CGG repeat expansions in the noncoding regions of two genes, LRP12 and GIPC1, have been reported to be causative for OPDM. Furthermore, neuronal intranuclear inclusion disease (NIID) has been recently reported to be caused by CGG repeat expansions in NOTCH2NLC.

Triggering factors for febrile attacks in Japanese patients with familial Mediterranean fever.
