Authors: Heo Seongkum , Doering Lynn V. , Widener Jeanne , Moser Debra K. 
Published: March 2020

Background Physical symptoms are common and distressing problems for patients with heart failure and may be the strongest predictor of health-related quality of life. Identification of variables predictive of physical symptom status is needed to develop effective interventions to improve health-related quality of life.
Methods A total of 84 patients discharged after being hospitalized for exacerbation of heart failure were followed up for 3 months. The Minnesota Living With Heart Failure Questionnaire and the Dyspnea-Fatigue Index were used to assess health-related quality of life and physical symptom status, respectively. Relationships of health-related quality of life and physical symptom status to baseline demographic, behavioral, biophysiological, and psychological variables were examined with bivariate correlations and stepwise multiple regression analyses.
Results Patients with better physical symptom status and those who worked, were older, and were less anxious at baseline reported better health-related quality of life (F=12.4, P&lt;.001); physical symptom status was the strongest predictor. Patients who had less depression, worked, had higher perceived control, and were younger at baseline reported better physical symptom status (F=14.4, P&lt;.001); depression was the strongest predictor.
Conclusions Physical symptom status is the most important predictor of health-related quality of life, and baseline depression and perceived control are the best predictors of physical symptom status. Interventions targeted to improve psychological status may improve physical symptom status and thereby improve health-related quality of life.

Authors: Hedges Christine , Redeker Nancy S. 
Published: March 2020

Background Off-pump coronary artery bypass surgical procedures have been advocated to reduce the adverse effects of cardiopulmonary bypass on the brain.
Objective To examine differences in objective and subjective characteristics of sleep and mood disturbance between patients after on-pump and off-pump coronary artery bypass surgery.
Methods In a secondary analysis of pooled data from 2 previous studies, sleep characteristics and mood disturbance on postoperative night 2 after transfer to the cardiac surgery step-down unit were compared in patients who had on-pump and off-pump cardiac surgery. The sample included 129 coronary artery bypass patients: 48 on-pump patients from one hospital and 81 off-pump patients from another hospital. Data were obtained with wrist actigraphs. Subjective characteristics of sleep were determined by using the Pittsburgh Sleep Quality Index and a sleep diary; mood disturbance was evaluated by using the short form of the Profile of Mood States.
Results Off-pump surgery was associated with better objective sleep continuity (decreased percentage of wake time after sleep onset and fewer awakenings) but not longer sleep duration after controlling for age and sex. The 2 groups of patients did not differ overall in subjective sleep characteristics, mood disturbance, or preoperative sleep quality.
Conclusion Use of off-pump coronary artery bypass surgery may improve sleep continuity during the early postoperative period. Prospective longitudinal studies are needed to evaluate the potential long-term benefits of this procedure during the different phases of recovery.

Background Mechanical ventilation increases risk for bleeding in the upper part of the gastrointestinal tract. Proton pump inhibitors, although they are more potent and longer acting inhibitors of gastric acid production than are histamine2 antagonists, also are generally more expensive. Data comparing the 2 types of agents for preventing gastrointestinal bleeding in critically ill patients are limited.Objectives To compare the effectiveness of famotidine (a histamine2 antagonist) and pantoprazole (a proton pump inhibitor) in preventing stress ulcers in critically ill patients receiving mechanical ventilation.Methods Data were collected from the Project Impact database. All patients who received mechanical ventilation for more than 48 hours from November 2002 to June 2006 and were treated with either drug were included. Patients receiving other drugs or with known bleeding in the upper part of the gastrointestinal tract, thrombocytopenia, or coagulopathy were excluded.Results A total of 522 patients who received famotidine and 95 who received pantoprazole were included. Bleeding in the upper part of the gastrointestinal tract was more common in patients receiving pantoprazole than in patients receiving famotidine (0.38% vs 3.2%, P= .03). Although scores on the Acute Physiology and Chronic Health Evaluation II were higher in patients who received pantoprazole (P= .01), other outcome measures did not differ significantly between groups. Bleeding in the upper part of the gastrointestinal tract was more frequent among dialysis patients receiving pantoprazole than among those receiving famotidine.Conclusions Famotidine and pantoprazole are similarly effective for preventing bleeding in the upper part of the gastrointestinal tract in patients receiving mechanical ventilation.
Novel Coronavirus Infection – Knowns and Unknowns with Particular Reference to Oncology – Combating against COVID-19 with “COVID”
Authors: Tsang Janice , Bajpai Jyoti 
Published: March 2020

AbstractWe are facing yet another global pandemic with the novel coronavirus (COVID-19) outbreak and anticipate that second and even third wave of the infection may come if we do not practise constant vigilance! An advent of a mysterious outbreak of atypical pneumonia in December 2019, traced from the seafood wholesale market in Wuhan of China, spread the wings over the world in very short span. Like both severe acute respiratory syndrome coronavirus (CoV) and MERS-CoV infections, the risk of severe disease increases substantially with age and with the presence of underlying conditions. While cancer is a prevalent disease and a global health challenge, little information is available with regard to the implications of COVID-19 for cancer patients. So far, the data have been limited and fragmented. COVID-19 with different primary cancer types will have different biological behaviours with highly variable disease courses and diverse treatment strategies. Any generalized conclusions for all cancer patients with respect to COVID-19 should be interpreted with caution until we have sufficient prospective data. Enormous work needs to be done to study the specific unmet needs of cancer patients with the challenge of the COVID-19; the prevention still is the best remedy. Infection control measures should be enforced continuously, and public health education and engagement should be highly recommended. We propose to join hands together to combat against COVID-19 with some simple tips for our cancer patients to raise their awareness of this public health challenge – combating against COVID-19 with “COVID:” Continue “social distancing;” Omit unnecessary face-to-face meting or meal gathering or mass event, make use of cyber meeting, and bring one's own lunch box to work; Visage protection, i.e. universal precaution with surgical masks when going out in a large crowd such as public transport or any close contact in high-risk area; Infection control of the hands with hand hygiene at all times and; Diet, lifestyle, and exercise continue to be balanced and healthy.

Background:
Laparoscopic Roux-en-Y gastric bypass (RYGB) has been proven to induce significant weight loss and remission of related co-morbidities in patients with morbid obesity. The long-term follow-up data show weight regain or failure to achieve complete remission of type 2 diabetes mellitus (T2DM) in some patients. In this study, we report weight loss patterns and remission of T2DM in patients with morbid obesity during a 5-year follow-up after RYGB.

Objective:
The objective was to evaluate outcomes during the follow-up on excess weight loss (EWL) and remission of T2DM after laparoscopic RYGB among Indian patients.

Setting:
The study was conducted in a tertiary care hospital, Kerala, India.

Materials and Methods:
This is a retrospective study in patients who underwent surgery between 2007 and 2010. The patient demographics, pre- and post-operative body mass index (BMI), co-morbidities and EWL were recorded from the medical records. These data were compared between pre-operative and follow-up intervals till 5 years using statistical approaches.

Results:
The study included 157 patients (91 males and 66 females) having a mean pre-operative BMI of 47.91 ± 7.01 kg/m2. A significant reduction in the BMI was observed at each follow-up point (P < 0.01) till 5 years after the surgery. The mean percentage of EWL increased from 34.57% ± 12.62% to 71.50% ± 15.41% from 3 months to 5 years after the surgery. Twelve per cent (n = 19) of patients achieved normal BMI (<25 mg/kg2) by 3rd year after the surgery. However, the remission of T2DM was achieved in >50% of patients within a year of surgery. During the 5th year, weight regain (1–22 kg) was observed in 36.70% (n = 58) patients, and recurrence of T2DM was observed in two patients.

Conclusions:
The long-term durability of RYGB in the study population was satisfactory with significant weight loss and remission of T2DM.

Background:
Although surgical resection is the main treatment for rectal cancer, the optimal surgical protocol for elderly patients with rectal cancer remains controversial. This study evaluated the feasibility of robot-assisted surgery in elderly patients with rectal cancer.

Patients and Methods:
This retrospective study enrolled 156 patients aged 28–93 years diagnosed with Stage I–III rectal cancer, who underwent robot-assisted surgery between May 2013 and December 2018 at a single institution.

Results:
In total, 156 patients with rectal cancer, including 126 non-elderly (aged < 70 years) and 30 elderly (aged ≥70 years) patients, who underwent robot-assisted surgery were recruited. Between the patient groups, the post-operative length of hospital stay did not differ statistically significantly (P = 0.084). The incidence of overall post-operative complications was statistically significantly lower in the elderly group (P = 0.002). The disease-free and overall survival did not differ statistically significantly between the two groups (P = 0.719 and 0.390, respectively).

Conclusions:
Robot-assisted surgery for rectal cancer was well tolerated by elderly patients, with similar results to the non-elderly patients. Oncological outcomes and survival did not depend on patient age, suggesting that robot-assisted surgery is a feasible surgical modality for treating operable rectal cancer and leads to age-independent post-operative outcomes in elderly patients.

Plas/Valburg na CBB/JPO? Een netwerkanalyse van rechtspraak over afgebroken onderhandelingen in de precontractuele fase
In de literatuur wordt betoogd dat CBB/JPO het leidende arrest is bij afgebroken onderhandelingen, en niet langer Plas/Valburg. Uit een uitgevoerde netwerkanalyse volgt dat Plas/Valburg minder vaak, maar nog altijd geregeld is aangehaald nadat CBB/JPO is gewezen. Een nadere inspectie laat zien dat er een tweedeling in de lagere rechtspraak bestaat: een groep uitspraken stelt onaanvaardbaar afbreken als voorwaarde voor de mogelijkheid om gemaakte kosten voor vergoeding in aanmerking te laten komen, in een andere groep uitspraken geldt die voorwaarde niet. Plas/Valburg wordt met name in de laatstgenoemde groep uitspraken geciteerd. Geconcludeerd wordt dat drie situaties denkbaar zijn: (1) afbreken staat vrij, geen verplichting tot het vergoeden van schade; (2) afbreken staat vrij, maar niet zonder vergoeding; en (3) afbreken is onaanvaardbaar. Plas/Valburg biedt voor geen van de situaties handvatten. CBB/JPO is leidend voor de laatste categorie, maar niet om te beoordelen of sprake is van welke van de twee andere scenario’s.

Zorgt een kwijtingsbeding inderdaad voor het definitief kwijtraken van vorderingsrechten?
In deze bijdrage staat het kwijtingsbeding in vaststellingsovereenkomsten centraal. Een ‘boilerplate’, omdat het beding in vrijwel elke vaststellingsovereenkomst voorkomt. Nadat het karakter van een vaststellingsovereenkomst in kaart wordt gebracht, worden de mogelijke rechtsgevolgen en de uitleg van een kwijtingsbeding besproken.
Characterization and performance of W-ZSM-5 and loaded Cu/ZsM-5 catalysts
Authors: Anggoro Didi Dwi , Amin Nor Aishah Saidina 
Published: March 2020

The metal oxides with sufficiently high dehydrogenation and low olefin oxidation activities reduces the acidity of ZSM-5. As a result, the metal containing ZSM-5 can produce higher hydrocarbons in methane oxidation. Many researchers studied the applicability of HZSM-5 and modify ZSM-5 to methane conversion to liquid hydrocarbons but result of their research still lead to low conversion and selectivity. The modified HZS-5 by loading with Tungsten (W) enhanced its heat resistant performance, and the high reaction temperature (800ºC) did not lead to the loss of W component by sublimation. The loading of HZSM-5 with Tungsten and Cooper (Cu) resulted in an increment in the methane conversion, CO2 and C5+ selectivities. In contrast, CO, C2-3, and H2O selectivities were reduced. The process to convert methane to liquid hydrocarbons (C5+) was dependent on the metal surface area and the acidity of zeolite. The high methane conversion and C5+ selectivity, and low H2O selectivity are obtained by using W/3.0Cu/HZSM-5. Keywords : Characterization W-ZSM-5, Modified HZSM-5, Tungsten, Copper, Methane Abstrak Logam oksida dengan kemampuan dehidrogenasi yang tinggi dan aktifasi oksidasi olefin berkurang dengan sifat keasaman dari ZSM-5. Sebagai hasilnya, ZSM-5 yang mengandung logam dapat memproduksi hidrokarbon rantai panjang dari oksidasi gas metana. Telah banyak para peneliti mempelajari kemampuan HZSM-5 dan ZSM-5 yang telah dimodifikasi untuk mengubah gas metana menjadi hidrokarbon cair tetapi hasil konversi dan selektivitasnya masih rendah. Modifikasi HZSM- 5 dengan penambahan logam Tungsten (W) meningkatkan daya tahan panas dan pada reaksi suhu tinggi (800ºC) tidak menyebabkan hilangnya logam W dikarenakan proses sublimasi. Penambahan logam Tungsten dan Copper (Cu) menyebabkan meningkatnya konversi metana, selektifitas CO2 dan C5+ Sebaliknya, selektifitas CO,C2-3, dan H2O menurun. Proses konversi metana menjadi hidrokarbon cair ditentukan oleh luas permukaan logam dan sifat keasaman dari zeolite. Penggunaan katalis W/3.0Cu/HZSM-5 menghasilkan konversi metana dan selektifitas C5+ tinggi dan selektifitas H2O rendah. Kata kunci : Karakterisasi W-ZSM-5, Modifikasi HZSM-5, Tungsten, Copper, Metana

AbstractFuel cell is a renewable energy source that does not create any negative effect to the environment. One of the advantage of the Solid Oxide Fuel Cell (SOFC) is its tolerance to fuel contaminants. This research is aimed to study the effect of propane addition into fuel gas on SOFC'S characters. SOFC tested during this research consists of main components functioned as feed gas distributor, and insulator made of asbestos and C-12 high alumina. SOFC's characters studied in this research including optimum operating conditions, polarization, and expected life time of the cell. The test results show that optimum operating conditions of tested SOFC are 700ºC, 45 mL H/minute and 225 mL air/minute. Cell using 22,2 %-vol propane in the fuel gives a longer lifetime, a smaller maximum current, and a higher voltage efficiency than such using hydrogen only as fuel. Propane concentration in fuel gas up to 22,2 %-vol has not any significant influence to cell voltage. The obtained polarization curve reveals that cell reactions are mass transfer controlled.Keywords: SOFC, Life Time, Polarization, EfficiencyAbstrakSel tunam oksida padat (SOFC) merupakan salah satu sumber energi terbarukan yang tidak menimbulkan dampak negatif terhadap lingkungan dan toleran terhadap kontaminan dalam bahan bakar.

Hard water magnetizing is applied as physical water treatment for reducing the formation of scale (CaCO3) in piping equipment and boiler Na2 CO3 and CaCl2 solution had been used as sample of hard water in many researches to investigate the influence of magnetic fields on CaCO3 formation. Na2 CO3 solution had been magnetized first before it was mixed with CaCl2 solution. By changing the strength of magnetic fields, exposed time, precipitated time, and temperature of sample, this study presents quantitative results of total scale deposit, total precipitated CaC03 and morphology of the deposits. This research was run by comparing magnetically and non-magnetically-treated samples. The results showed a decrease of deposits formation rate and total amount of precipitated CaCO3 of magnetically-treated samples. An increase in precipitation temperature increased the total amount of precipitated CaCO3 and the maximum precipitation was achieved at the 50°C. Microscope images showed that a smaller amount but larger size of CaCO3 particles formed in magnetically-treated samples. X-ray diffraction (XRD) analysis showed that samples contain mostly calcite. This research's result showed that magnetization of Na2 CO3 solution could reduce formation rate of CaCO3 either in solution or in the surface of hard water.Keywords: Magnetic Treatment, Hard Water; Calcium Carbonate Precipitation; CaCO3 Deposit Morphology AbstrakMagnetisasi air sadah merupakan proses fisik yang bertujuan menekan terbentuknya kerak (CaCO3) pada sistem perpipaan dan boiler. Campuran larutan Na2 CO3 dan CaCl2 banyak digunakan sebagai model air sadah sintetik guna mengamati pengaruh medan magnet terhadap pembentukan CaCO3 dalam air sadah. Larutan Na2 CO3 dimagnetisasi terlebih dahulu sebelum dicampur dengan larutan CaCl2 Variabel proses meliputi waktu magnetisasi, waktu presipitasi, kuat medan, dan suhu larutan sampel sementara parameter yang akan diamati adalah jumlah deposit CaCO3 jumlah presipitasi total CaCO3 dan morfologi deposit CaCO3. Perbandingan parameter pengamatan dilakukan terhadap sampel yang dimagnetisasi dan sampel non-magnetisasi. Hasil percobaan menunjukkan adanya penurunan pembentukan deposit dan presipitasi total CaCO3 pada sampel yang dimagnetisasi dibanding sampel non-magnetisasi. Peningkatan suhu presipitasi CaCO3 meningkatkan jumlah presipitasi total CaCO3 dan harga maksimum deposit CaCO3 yang terbentuk dicapai pada suhu 50°C. Hasil foto mikroskop menunjukkan jumlah partikel CaCO3 yang terbentuk pada sampel yang dimagnetisasi lebih sedikit dan ukuran partikelnya lebih besar dibanding sampel non-magnetisasi. Hasil uji XRD menunjukkan hanya kristal kalsit yang dominan pada kedua jenis sampel. Hasil penelitian ini menunjukkan bahwa magnetisasi larutan Na2 CO3 dapat menahan laju pembentukan CaCO3 dilarutan maupun dipermukaan pada air sadah.Kata Kunci: Perlakuan Magnetik, Air Sadah, Presipitasi Kalsium Karbonat, Morfologi Deposit CaCO3
