Background: Mental health problems among expectant and nursing mothers also affect their infants, partners, and families. While physical activity is a potential method for preventing postpartum depression (PPD), it is difficult for postpartum women to find the time for physical exercise. A recent study reported that improving communication between expectant couples can be used as a preventive intervention for PPD, and a systematic review and meta-analysis recently reported decreased facial emotional expressivity in individuals with different non-psychotic disorders.

Article Synopsis
  • HBV reactivation poses a risk for patients undergoing treatment with anti-CD20 antibodies for lymphoma, and this study analyzed an ultra-high sensitivity HBsAg test to improve preemptive antiviral treatment in those with resolved HBV infections.
  • Among 252 patients, 22 experienced HBV reactivation, with the new assay identifying significantly more cases compared to the conventional method, particularly detecting precore mutants linked to higher reactivation rates.
  • Key findings indicated that low anti-HBs titer, detectable HBV DNA below quantification, and positive HBsAg results from the ultra-sensitive assay were strong independent risk factors for HBV reactivation, suggesting its utility in monitoring patients at risk.

Aim: Facial expressions are often impaired in patients with Parkinson's disease (PD). Few studies have examined the effects of head and neck rehabilitation in patients with PD using a facial expression analysis. In the present study, to further elucidate the effects of facial rehabilitation exercise in patients with PD, a three-dimensional facial expression analysis with FaceReader™ and surface electromyography (EMG) were performed in order to assess the facial expressions and muscle activities, respectively.

Introduction: This subgroup analysis of the LYM-3002 Phase III study (NCT00722137) investigated whether substituting bortezomib for vincristine in frontline R-CHOP (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone) therapy could improve outcomes in East Asian patients with newly diagnosed mantle-cell lymphoma (MCL).

Materials And Methods: A total of 121 East Asian patients from China, Taiwan, Japan, and the Republic of Korea with stage II-IV MCL who were ineligible or not considered for stem-cell transplantation were enrolled to six to eight 21-day cycles of R-CHOP or VR-CAP (R-CHOP with bortezomib replacing vincristine).

Results: The primary end point was progression-free survival.

Aim: Although it is well documented that exercising is good for the mental health and cognitive function as well as the physical condition in elderly people, exercising is difficult in elderly individuals with a low motor function. To develop an exercise program targeting elderly individuals unsuited for whole-body exercises, we assessed the effects of facial exercises on the mental health in healthy elderly people.

Methods: Community-dwelling older adults (N = 75, age range = 65-87 years) were randomly divided into a facial exercises group and a wait-listed control group.

Article Synopsis
  • * The study analyzed 1220 untreated DLBCL patients using the standard international prognostic index (IPI) and the CNS-IPI model, revealing varying cumulative incidences of CNS involvement across risk groups over two years.
  • * Despite lower risk classifications with the standard IPI, patients with breast and testis involvement showed higher rates of CNS involvement, indicating they may benefit from prophylactic treatment regardless of their IPI risk level.

The pivotal LYM-3002 study compared frontline rituximab plus cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) with bortezomib, rituximab, cyclophosphamide, doxorubicin and prednisone (VR-CAP) in newly diagnosed mantle cell lymphoma (MCL) patients for whom stem cell transplantation was not an option. This post hoc subanalysis of the VR-CAP data from LYM-3002 evaluated the effect of bortezomib dose intensity on OS in patients who completed ≥6 cycles of treatment. From the end of cycle 6, patients receiving ≥4.

Background: There is no standard management of reactivation of hepatitis B virus (HBV) infection in HBV-resolved patients without hepatitis B surface antigen (HBsAg), but with antibodies against hepatitis B core antigen and/or antibodies against HBsAg (anti-HBs).

Methods: We conducted a prospective observational study to evaluate the occurrence of HBV reactivation by serial monthly monitoring of HBV DNA and to establish preemptive therapy guided by this monitoring in B-cell non-Hodgkin lymphoma (B-NHL) treated with rituximab plus corticosteroid-containing chemotherapy (R-steroid-chemo). The primary endpoint was the incidence of HBV reactivation defined as quantifiable HBV DNA levels of ≥ 11 IU/mL.

Background: The proteasome inhibitor bortezomib was initially approved for the treatment of relapsed mantle-cell lymphoma. We investigated whether substituting bortezomib for vincristine in frontline therapy with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) could improve outcomes in patients with newly diagnosed mantle-cell lymphoma.

Methods: In this phase 3 trial, we randomly assigned 487 adults with newly diagnosed mantle-cell lymphoma who were ineligible or not considered for stem-cell transplantation to receive six to eight 21-day cycles of R-CHOP intravenously on day 1 (with prednisone administered orally on days 1 to 5) or VR-CAP (R-CHOP regimen, but replacing vincristine with bortezomib at a dose of 1.

Erythropoiesis-stimulating agents (ESA) reduce the need for transfusions and improve the quality of life in patients receiving chemotherapy, but several clinical trials have suggested that ESA might have a negative impact on survival. To evaluate the efficacy and safety of ESA, epoetin beta and darbepoetin alfa, including their impact on overall survival and thromboembolic events, we conducted an individual data-based meta-analysis of three randomized, placebo-controlled trials studying Japanese patients with chemotherapy-induced anemia. All trials were conducted in compliance with Good Clinical Practice.

CHOP has been the standard chemotherapy for aggressive non-Hodgkin's lymphoma (NHL). However, indolent NHL remains largely an incurable diseases, with nearly static overall survival, and only 40% of patients with aggressive NHL are cured by CHOP. Monoclonal antibodies are an exciting advance in the treatment of lymphoma.

Patients who will receive chemotherapy require careful assessment of liver function prior to treatment to determine which drugs are not appropriate, and which drugs need dose modification. However, if the hepatic parenchymal abnormalities are caused by an underlying neoplasm and the neoplasm is sensitive to the drugs, it may not be necessary to reduce the dose. Clearly, this is an area where clinical judgment must be used to assess the risk/benefit ratio.
