Pharmacist Interventions for Adverse Drug Reactions in Palliative Care: A Multicentre Pilot Study.

This study aimed to investigate adverse reactions to medications administered during palliative care and compare the responses of Board-Certified Pharmacists in Palliative Pharmacy (BCPPP) and non-BCPPP professionals. Methods: This multicentre prospective survey included hospital and community pharmacists who are members of the Japanese Society for Pharmaceutical Palliative Care and Sciences. Study participants included patients who experienced new drug reactions during the study period and responded to the requested survey items. The follow-up period for each eligible patient began on the day the pharmacists initiated the intervention and ended at discharge, death, or after one month of intervention. The primary endpoint was the impact of pharmacist intervention on adverse drug reactions. The pharmacists included in the study evaluated the severity of adverse drug reactions to assess the effect of their intervention using an integrated palliative care outcome scale before and after the intervention. Key findings: During the survey period, 79 adverse drug reaction intervention reports from 69 patients were obtained from 54 pharmacists (28 certified and 26 non-certified). The response rate was 1.62% (54/3,343). The management of palliative pharmacotherapy side effects by BCPPP and non-BCPPP significantly improved the patients' activities of daily living (P < 0.001). The BCPPP group intervened for significantly more patients with adverse drug reactions and overall adverse drug reactions than the non-BCPPP group (P < 0.023 and P < 0.013, respectively). Conclusion: BCPPP interventions can improve symptom management.

Breast adenomyoepithelioma from a radiologic perspective.

Adenomyoepithelioma of the breast (AB) is an uncommon tumor that is characterized by the biphasic proliferation of epithelial and myoepithelial cells. The radiologic findings for AB have been scantly reported. This paper aims to analyze the characteristic findings for AB on ultrasonography (US) and mammography. This retrospective descriptive study used the Breast Imaging-Reporting and Data System (BI-RADS) to analyze the US and mammography findings for histologically confirmed AB in patients attended at our institution between 2007 and 2019. We identified a total of 13 AB in 13 women. All patients underwent US. On US, 12 lesions were seen as oval nodules, and the remaining lesion was irregular-shaped; 8 lesions had circumscribed margins, 3 had angled margins, and 2 had microlobulated margins. Regarding the echo pattern, 8 lesions were hypoechoic and 5 were complex (solid-cystic). On color Doppler, 11 lesions were vascularized nodules and 2 were avascular nodules. In conclusion, we present the imaging characteristics for a series of cases of AB. It is unlikely that this lesion can be suspected solely on the basis of the imaging findings; nevertheless, it is important for radiologists to be familiar with AB to carry out a good radiopathologic correlation.

Homodyne interferometry using a phase rotator for calibration of sine-cosine phase detection of a 70 GHz probe beam through a plasma.

Homodyne interferometry using a motorized phase rotator for calibration of sine-cosine detection of the phase shift of a 70 GHz probe beam through a plasma has been developed. Four interferometers based on this interferometry have been installed on the low aspect ratio torus experiment (LATE) device with four horizontal probe beams on the mid-plane, which has measured the line-integrated electron densities with a time resolution of 10 µs and a resolution of line-integrated density of 5 × 1015 m-2.

Prevalence of Prefrailty and Frailty in South America: A Systematic Review of Observational Studies.

OBJECTIVES: The present study aimed at investigating the prevalence of prefrailty and frailty in South American older adults according to the setting and region. DESIGN: A literature search combining the terms "frailty", "South America" or a specific country name was performed on PubMed, EMBASE, Lilacs, and Scielo to retrieve articles published in English, Portuguese or Spanish on or before August 2019. PARTICIPANTS: Older adults aged 60+ years from any setting classified as frail according to a validated scale were included in the study. MEASUREMENTS: Frailty assessment by a validated scale. RESULTS: One-hundred eighteen reports (98 performed from Brazil, seven from Chile, five from Peru, four from Colombia, two from Ecuador, one from Argentina, and one from Venezuela) were included in the study. The mean prevalence of prefrailty in South America was 46.8% (50.7% in older in-patients, 47.6% in the community, and 29.8% in nursing-home residents). The mean prevalence of frailty in South America was 21.7% (55.8% in nursing-home residents, 39.1% in hospitalized older adults, and 23.0% in the community). CONCLUSIONS: Prefrailty and frailty are highly prevalent in South American older adults, with rates higher than those reported in Europe and Asia. In the community, almost one-in-two is prefrail and one-in-five is frail, while hospitalized persons and nursing-home residents are more frequently affected. These findings indicate the need for immediate attention to avoid frailty progression toward negative health outcomes. Our findings also highlight the need for specific guidelines for the management of frailty in South America.

Perinatal rib fractures in 18 calves delivered from Holstein dams.

Cranial rib fractures during dystocia and the ensuing callus formations in calves often cause tracheal stenosis. Rib fractures may affect the lung since ribs tend to fracture above the costochondral junction during delivery. Considering that calving assistance rates for dystocia are high, calves with fractured ribs may develop respiratory disease which results in economic loss. The objective of this study was to elucidate the contribution of rib fractures to economic loss through respiratory disease in calves. Of 163 sick calves delivered from Holstein-Friesian dams included in this study, a total of 18 rib fractured calves was found, giving an incidence of rib fracture in sick calves of 11.0%. There were significant differences in incidence by the rib involved, indicating the 2nd to 7th ribs tend to break. Many of the rib fractured calves showed dyspnea and pyrexia. In this study, four of five scanned or necropsied calves had pneumonia lesions despite the fact that these four calves did not have tracheal stenosis. Rib fractured calves sold at below market value with a median difference from average sale price of minus 64,861 yen. Survival analysis indicated an overall association between rib fracture and time to death. In this study, we demonstrated that rib fractures happened most frequently in the 2nd to 7th ribs, and these cases tended to cause pneumonia, which decreased sale prices and longevity. Farmers should work to reduce risks and rates of dystocia so as to lessen economic loss and poor welfare in calves due to rib fractures.

Usefulness of medication instruction sheets for sharing information on cancer chemotherapy within the health care team.

Patients receiving cancer chemotherapy may experience a number of potentially severe adverse drug reactions. It is crucial for all members of the health care team to monitor the effect of medicines on the patient to ensure the safety and efficacy of the chemotherapy. The present study prepared medication instruction sheets (MISs) on hematological malignancy and conducted a questionnaire survey to verify their usefulness among physicians, dentists, and nurses. MISs were prepared for 103 chemotherapy and 44 pretreatment regimens for hematopoietic stem cell transplantation in the Department of Hematology at Kyushu University Hospital. Eight questions were prepared to investigate whether MISs could help physicians, dentists, and nurses manage cancer chemotherapy more safely, effectively, and efficiently, as well as in the sharing of information. A total of 35 medical staff working in inpatient wards, including 8 physicians, 3 dentists, and 24 nurses, participated in the questionnaire survey. All of the staff responded to the questionnaire survey, which showed that the MISs were favorably accepted by the participants. There was no negative opinion on the management of chemotherapy using the MISs. The MIS was a useful tool for sharing information on cancer chemotherapy between patients and medical staff and for enabling efficient management, thereby improving the safety and efficacy of treatment.

Impact of a systematic education model for palliative care in cancer.

In clinical practice, pharmacists are continually required to improve their knowledge and expertise; however, the postgraduate education system for professional development cannot be confidently stated to be well established. The establishment of a systematic and multifaceted educational curriculum should be useful to improve home care and pharmacists' contribution; therefore, we developed a curriculum in collaboration with the university faculty of pharmaceutical sciences, department of pharmacy in hospital, and the Fukuoka Pharmaceutical Association. Class topics were extracted from the "Kanwa-Iryou-Yakugaku", edited by the Japanese Society for Pharmaceutical Palliative Care and Sciences. The items are necessary to perform palliative care as a pharmacist. A class schedule of 6 days (24 classes in total) was formulated. Questionnaires on comprehension degree before and after each class were provided to the participants. Comprehension was assessed on a scale of 1 to 10, where "I do not understand at all" was 1 and "I understand enough" was 10. The average recovery rates of questionnaires from each class were 92.6 % and 88.9 % before and after class, respectively. The average number of participants who completely answered the questionnaire before and after class was 45.6; therefore, these data were analyzed. Comprehension degree on each topic had significantly increased after attendance of all classes (p < 0.01). The comprehension degree of participants of the medical science of palliative care did greatly improve. Consequently, it is clear that the standard education model constructed was meaningful for the professional development of pharmacists in palliative care medicine.

Expression of apoptosis inhibitor of macrophages in tissue macrophages, leukocytes and vascular endothelial cells of dogs.

Apoptosis inhibitor of macrophages (AIM) is a protein which plays important roles in controlling the immune response and inflammation in human and mice. In dogs, AIM is reported to be expressed in cancerated macrophages and regulate the survival of these tumor cells. In this study, to elucidate the physiological expression pattern of AIM in dogs, systemic expression and distribution of AIM of dogs were investigated. Mature healthy Beagles were used. Various tissues, peripheral blood cells, and bone marrow cells of normal dogs were collected for in situ hybridization, real-time RT-PCR, and immunohistochemistry. AIM mRNA and protein were expressed in tissue macrophages of the spleen, liver, lungs, and lymph nodes, but not in the microglia of the cerebrum. Proximal tubules in the kidney also expressed AIM protein. Monocytes and B lymphocytes in circulating blood and a part of microvasculature endothelial cells showed AIM expression at both the mRNA and protein levels. In the bone marrow, early-stage monocyte progenitor-like cells expressed AIM mRNA and protein. These results clarified that AIM is expressed in more cell types than previously reported in human and mice. These data spread the possibility of AIM physiological functions and implies the relationship of AIM to the maturation of macrophage-strain cells in dogs and other species.

Evaluation of the compliance with antiemetic guidelines for prevention of chemotherapy-induced nausea and vomiting in patients with hematologic malignancy.

To assess compliance with the Japanese antiemetic guidelines for chemotherapy-induced nausea and vomiting (CINV), the frequencies of CINV occurrence and use of antiemetic rescue medications were examined in patients with hematological malignancy. A total of 40 patients with hematologic malignancy were eligible in this study. This study was performed in the Department of Hematology, Kyushu University Hospital, as a subgroup analysis from a nationwide, multicenter prospective cohort study conducted by the CINV Study Group of Japan. In the patients with hematological malignancy, the guideline compliance rate was 45 %. Five patients (22.7 %) experienced vomiting during the observation period after receiving non-guideline-consistent antiemetic prophylaxis, whereas no patient experienced vomiting after receiving guideline-consistent antiemetic prophylaxis. The study was not sufficiently powered to reach a statistical significance in its frequency of occurrence between the compliance and non-compliance groups. In the entire study period, 8 out of 40 patients required rescue medication, but there was no association between the status of compliance and the antiemetic guidelines. A total of 22 (55.0 %) patients achieved complete response, which was defined as no vomiting and no use of antiemetic rescue medication, during the study period. The rate of compliance with the prophylactic antiemetic treatment guidelines seemed to be low in patients with hematological malignancy, although the status of the guideline compliance did not always influence the antiemetic effects.

Comparison of antiemetic effects of granisetron and palonosetron in patients receiving bendamustine-based chemotherapy.

The antiemetic effects and safety of granisetron and palonosetron against chemotherapy-induced nausea and vomiting (CINV) were retrospectively evaluated in patients with non-Hodgkin lymphoma receiving bendamustine-based chemotherapy. A total of 61 patients were eligible for this study. Before starting the bendamustine-based chemotherapy, granisetron or palonosetron were intravenously administered with or without aprepitant and/or dexamethasone. The proportions of patients with complete control (CC) during the overall (during the 6 days after the start of the chemotherapy), acute (up to 2 days), and delayed (3 to 6 days) phases were assessed. CC was defined as complete response with only grade 0-1 nausea, no vomiting, and no use of antiemetic rescue medication. Granisetron or palonosetron alone were administered to 9 and 19 patients, respectively. Aprepitant and/or dexamethasone were combined with granisetron and palonosetron in 28 and 5 patients, respectively. Acute CINV was completely controlled in all patients. Both granisetron monotherapy and palonosetron combination therapy could provide good control of delayed CINV, although the CC rates during the delayed and overall phases were not significantly different among mono- and combination therapy of the antiemetics. There was no significant difference in the frequencies of adverse drug events between the granisetron and palonosetron treatment groups. The present study showed that the antiemetic efficacy and safety of granisetron-based therapy were non-inferior to those of palonosetron-based therapy. Taken together with treatment costs, granisetron monotherapy would be adequate to prevent CINV in patients with non-Hodgkin lymphoma receiving bendamustine-based chemotherapy.

Oxidative stress serves as a key checkpoint for IL-33 release by airway epithelium.

BACKGROUND: Interleukin (IL)-33 is implicated in the pathophysiology of asthma and allergic diseases. However, our knowledge is limited regarding how IL-33 release is controlled. The transcription factor nuclear factor-erythroid-2-related factor 2 (Nrf2) plays a key role in antioxidant response regulation. OBJECTIVE: The goal of this project was to investigate the role of cellular oxidative stress in controlling IL-33 release in airway epithelium. METHODS: Complementary approaches were used that included human bronchial epithelial cells and mouse models of airway type-2 immunity that were exposed to fungus Alternaria extract. The clinically available Nrf2 activator 2-cyano-3,12-dioxooleana-1,9-dien-28-oic acid methyl ester (CDDO-Me) was used to evaluate the role of Nrf2-induced antioxidant molecules. RESULTS: Human bronchial epithelial cells produced reactive oxygen species (ROS) when they were exposed to Alternaria extract. ROS scavengers, such as glutathione (GSH) and N-acetyl cysteine, prevented extracellular secretion of ATP and increases in intracellular calcium concentrations that precede IL-33 release. Administration of CDDO-Me to mice enhanced expression of a number of antioxidant molecules in the lungs and elevated lung levels of endogenous GSH. Importantly, CDDO-Me treatment reduced allergen-induced ATP secretion and IL-33 release by airway epithelial cells in vitro and protected mice from IL-33 release and asthma-like pathological changes in the lungs. CONCLUSIONS: The balance between oxidative stress and antioxidant responses plays a key role in controlling IL-33 release in airway epithelium. The therapeutic potential of Nrf2 activators needs to be considered for asthma and allergic airway diseases.

Biomedical and Catalytic Opportunities of Virus-Like Particles in Nanotechnology.

Within biology, molecules are arranged in hierarchical structures that coordinate and control the many processes that allow for complex organisms to exist. Proteins and other functional macromolecules are often studied outside their natural nanostructural context because it remains difficult to create controlled arrangements of proteins at this size scale. Viruses are elegantly simple nanosystems that exist at the interface of living organisms and nonliving biological machines. Studied and viewed primarily as pathogens to be combatted, viruses have emerged as models of structural efficiency at the nanoscale and have spurred the development of biomimetic nanoparticle systems. Virus-like particles (VLPs) are noninfectious protein cages derived from viruses or other cage-forming systems. VLPs provide incredibly regular scaffolds for building at the nanoscale. Composed of self-assembling protein subunits, VLPs provide both a model for studying materials' assembly at the nanoscale and useful building blocks for materials design. The robustness and degree of understanding of many VLP structures allow for the ready use of these systems as versatile nanoparticle platforms for the conjugation of active molecules or as scaffolds for the structural organization of chemical processes. Lastly the prevalence of viruses in all domains of life has led to unique activities of VLPs in biological systems most notably the immune system. Here we discuss recent efforts to apply VLPs in a wide variety of applications with the aim of highlighting how the common structural elements of VLPs have led to their emergence as paradigms for the understanding and design of biological nanomaterials.

Can subsyndromal manifestations of major depression be identified in children at risk?

OBJECTIVE: Children of parents with major depression are at significantly increased risk for developing major depression themselves; however, not all children at genetic risk will develop major depressive disorder (MDD). We investigated the utility of subsyndromal scores on the Child Behavior Checklist (CBCL) Anxiety/Depression scale in identifying children at the highest risk for pediatric MDD from among the pool of children of parents with MDD or bipolar disorder. METHOD: The sample was derived from two previously conducted longitudinal case-control family studies of psychiatrically and pediatrically referred youth and their families. For this study, probands were stratified based on the presence or absence of a parental mood disorder. RESULTS: Subsyndromal scores on the CBCL Anxiety/Depression scale significantly separated the children at high risk for pediatric MDD from those at low risk in a variety of functional areas, including social and academic functioning. Additionally, children at genetic risk without elevated CBCL Anxiety/Depression scale scores were largely indistinguishable from controls. CONCLUSION: These results suggest that the CBCL Anxiety/Depression scale can help identify children at highest risk for pediatric MDD. If implemented clinically, this scale would cost-effectively screen children and identify those most in need of early intervention resources to impede the progression of depression.

Effect of cooking classes for housewives on salt reduction in family members: a cluster randomized controlled trial.

OBJECTIVES: Sodium reduction is very important in preventing cardiovascular diseases, especially in regions with high salt intake such as Japan. One strategy for salt reduction is to raise consumer awareness of the need to reduce daily salt intake. We investigated whether cooking classes given to housewives focussing on salt reduction would influence not only their own consumption behaviour but also that of their family members. STUDY DESIGN: Single-blinded, cluster randomized trial. METHODS: We randomly assigned housewives to participate in cooking classes focussing on salt reduction (intervention group) or lectures about a healthy lifestyle (control group). The main outcome measure was the difference in estimated daily salt intake by spot urine sampling of housewives and their family members 2 months after intervention between the groups. RESULTS: A total of 35 housewives and 33 family members were randomized. The mean daily salt intake was 10.00 (standard deviation [SD] 1.75) g/day in the control group (17 housewives and 15 family members) and 9.57 (SD 2.45) g/day in the intervention group (18 housewives and 18 family members) at baseline. Two months after the intervention, the mean salt intake was 10.30 (SD 1.78) g/day in the control group and 8.95 (SD 2.45) g/day in the intervention group. The mean difference was -1.19 g/day (95% confidence interval -2.29, -0.09; P = 0.034). A similar tendency was observed in the subgroups of housewives and family members. CONCLUSIONS: Our trial suggested that the effects of cooking classes focussing on salt reduction for housewives could be transferred to family members (UMIN-CTR: 000018870).

Evolution of Insulator-Metal Phase Transitions in Epitaxial Tungsten Oxide Films during Electrolyte-Gating.

An interface between an oxide and an electrolyte gives rise to various processes as exemplified by electrostatic charge accumulation/depletion and electrochemical reactions such as intercalation/decalation under electric field. Here we directly compare typical device operations of those in electric double layer transistor geometry by adopting A-site vacant perovskite WO3 epitaxial thin films as a channel material and two different electrolytes as gating agent. In situ measurements of X-ray diffraction and channel resistance performed during the gating revealed that in both the cases WO3 thin film reaches a new metallic state through multiple phase transitions, accompanied by the change in out-of-plane lattice constant. Electrons are electrostatically accumulated from the interface side with an ionic liquid, while alkaline metal ions are more uniformly intercalated into the film with a polymer electrolyte. We systematically demonstrate this difference in the electrostatic and electrochemical processes, by comparing doped carrier density, lattice deformation behavior, and time constant of the phase transitions.

Strain Control of Fermiology and Many-Body Interactions in Two-Dimensional Ruthenates.

Here we demonstrate how the Fermi surface topology and quantum many-body interactions can be manipulated via epitaxial strain in the spin-triplet superconductor Sr_{2}RuO_{4} and its isoelectronic counterpart Ba_{2}RuO_{4} using oxide molecular beam epitaxy, in situ angle-resolved photoemission spectroscopy, and transport measurements. Near the topological transition of the γ Fermi surface sheet, we observe clear signatures of critical fluctuations, while the quasiparticle mass enhancement is found to increase rapidly and monotonically with increasing Ru-O bond distance. Our work demonstrates the possibilities for using epitaxial strain as a disorder-free means of manipulating emergent properties, many-body interactions, and potentially the superconductivity in correlated materials.

Direct Observation of Electrostatically Driven Band Gap Renormalization in a Degenerate Perovskite Transparent Conducting Oxide.

We have directly measured the band gap renormalization associated with the Moss-Burstein shift in the perovskite transparent conducting oxide (TCO), La-doped BaSnO_{3}, using hard x-ray photoelectron spectroscopy. We determine that the band gap renormalization is almost entirely associated with the evolution of the conduction band. Our experimental results are supported by hybrid density functional theory supercell calculations. We determine that unlike conventional TCOs where interactions with the dopant orbitals are important, the band gap renormalization in La-BaSnO_{3} is driven purely by electrostatic interactions.

Formation and Observation of a Quasi-Two-Dimensional dxy Electron Liquid in Epitaxially Stabilized Sr(2-x)La(x)TiO4 Thin Films.

We report the formation and observation of an electron liquid in Sr(2-x)La(x)TiO4, the quasi-two-dimensional counterpart of SrTiO3, through reactive molecular-beam epitaxy and in situ angle-resolved photoemission spectroscopy. The lowest lying states are found to be comprised of Ti 3d_{xy} orbitals, analogous to the LaAlO3/SrTiO3 interface and exhibit unusually broad features characterized by quantized energy levels and a reduced Luttinger volume. Using model calculations, we explain these characteristics through an interplay of disorder and electron-phonon coupling acting cooperatively at similar energy scales, which provides a possible mechanism for explaining the low free carrier concentrations observed at various oxide heterostructures such as the LaAlO3/SrTiO3 interface.
