Introduction of Various Models of Palliative Oncology Care: A Systematic Review.

BACKGROUND: The aim of this study is to synthesize the existing evidence on various palliative care models for cancer patients. This effort seeks to discern which facets of PC models are suitable for various patient cohorts, elucidate their mechanisms, and clarify the circumstances in which these models operate. METHODS: A comprehensive search was performed using MeSH terms related to PC and cancer across various databases. The Preferred Reporting Items for Systematic Reviews and a comprehensive evidence map were also applied. RESULTS: Thirty-three reviews were published between 2009 and 2023. The conceptual PC models can be classified broadly into time-based, provider-based, disease-based, nurse-based, issue-based, system-based, team-based, non-hospice-based, hospital-based, community-based, telehealth-based, and setting-based models. The study argues that the outcomes of PC encompass timely symptom management, longitudinal psychosocial support, enhanced communication, and decision-making. Referral methods to specialized PC services include oncologist-initiated referral based on clinical judgment alone, via referral criteria, automatic referral at the diagnosis of advanced cancer, or referral based on symptoms or other triggers. CONCLUSION: The gold standard for selecting a PC model in the context of oncology is a model that ensures broad availability of early PC for all patients and provides well-timed, scheduled, and specialized care for patients with the greatest requirement.

Biochemical Markers of Early Renal Dysfunction in Patients with ß-thalassemia Major: A Systematic Review and Meta-analysis.

BACKGROUND: Early diagnosis of renal dysfunction in ß-thalassemia major (ß- TM) may help take specific measures to delay irreversible damage and renal failure. Therefore, the present meta-analysis aimed to compare biochemical markers of premature renal dysfunction between ß-TM and healthy subjects and identify renal issues' prevalence in patients with ß-TM. METHODS: We searched PubMed, Cumulative Index of Nursing and Allied Health Literature (CINAHL), Medline, Scopus, Web of Science, ScienceDirect, ProQuest, Google Scholar, and State Inpatient Databases (SIDs) without any language constraints for all relevant articles published up to April 2019. RESULTS: Out of 1458 articles published up to April 2019, 24 case-control and 22 crosssectional studies were investigated. The investigated levels of serum phosphorus, uric acid (UA), cystatin C, and ferritin were significantly different between ß-TM patients and controls. The albumin/creatinine ratio (ACR), N-acetyl-ß-D-glucosaminidase/creatinine (NAG/Cr) ratio, urinary and serum ß2 microglobulin (ß2MG), and serum ferritin levels were significantly higher in ß-TM patients than in healthy individuals. However, glomerular filtration rate, creatinine clearance, and pretransfusion hemoglobin indicated a significantly lower rate. The general prevalence of renal glomerular and/or tubular defects in patients with ß-TM was 50.22%. CONCLUSION: Urinary NAG, ß2MG, ACR, and Scys-C may be early markers of renal dysfunction in patients with ß-thalassemia major. An observation of elevated levels of these markers despite normal levels of other markers of renal dysfunction may indicate primary, subclinical injury to the renal tubules and glomeruli.

Effectiveness of Fortified Garlic Extract Oral Capsules as Adjuvant Therapy in Hospitalized Patients with Coronavirus Disease 2019: A Triple-Blind Randomized Controlled Clinical Trial.

Background: Herbal medicines have been extensively used to treat coronavirus disease 2019 (COVID-19). Garlic, known to exert antiviral and anti-inflammatory effects, can be coadministered with standard treatments to combat COVID-19. Objectives: The aim of the study was to evaluate the efficacy and safety profile of Gallecina oral capsules (Samisaz Pharmaceutical Company, Mashhad, Iran), a fortified garlic extract, as adjunctive therapy to improve the clinical status and symptoms in noncritically ill patients hospitalized for COVID-19. Methods: This triple-blind randomized, placebo-controlled clinical trial was conducted on noncritically ill patients with COVID-19 hospitalized in the nonintensive care wards of Imam Hassan Hospital. Patients received remdesivir plus 90 mg Gallecina capsule or a placebo every 8 hours for 5 days or until discharge. The clinical status, respiratory symptoms, and laboratory parameters were recorded during the study period. Results: Patients were enrolled between April 24 and July 18, 2021. Data from 72 patients in the Gallecina group and 69 patients in the placebo group were analyzed. Oxygen saturation, C-reactive protein levels, and the distribution of respiratory distress and cough were similar between groups on the day of discharge. Although body temperature was significantly lower in the Gallecina group than that in the placebo group on the day of discharge (P = 0.04), it was within the normal range for both groups. The proportion of patients requiring supplemental oxygen for at least 1 day during the study was significantly reduced in the Gallecina group on days 3 and 4 and the day of discharge (P < 0.05). Gastrointestinal complaints were more prevalent in the Gallecina group than in the placebo group but the difference was not statistically significant (P = 0.12). Conclusions: There was no significant effect on the primary outcome of clinical status on study day 6. Although the proportion of Gallecina-treated patients who needed supplemental oxygen significantly decreased on days 3 and 4 and the day of discharge, there was no significant difference between the groups on other days. The possible beneficial effects on oxygen requirements in noncritically ill COVID-19 patients may warrant further investigation. (Curr Ther Res Clin Exp. 2023; 84:XXX-XXX).

Side effects of Sputnik V, Oxford-AstraZeneca, Sinopharm, and Covaxin and their associations with other variables among healthcare workers of a tertiary hospital in Iran.

BACKGROUND: Misinformation about the prevalence of COVID-19 vaccines' side effects (SEs) has led to concerns about and mistrust of vaccine safety. Thus, this study aimed to evaluate the prevalence of COVID-19 vaccines' SEs. METHODS: In a cross-sectional survey-based study on the healthcare workers (HCWs) of a tertiary hospital in Iran, the SEs of Sputnik V, Oxford-AstraZeneca, Sinopharm, and Covaxin were evaluated through a face-to-face interview by a researcher-made questionnaire. RESULTS: A total of 368 HCWs received at least one dose of a COVID-19 vaccine. The prevalence of people with at least one SE was higher among those who received the Oxford-AstraZeneca (95.8 %) and Sputnik V (92.1 %) vaccines than those who received Covaxin (70.5 %) or Sinopharm (66.7 %). Following the first and second doses, injection site pain (50.3 % and 58.2 %), body/muscle pain (53.5 % and 39.4 %), fever (54.5 % and 32.9 %), headache (41.3 % and 36.5 %), and fatigue (44.4 % and 32.4 %) were the most common SEs. Overall, SEs were often initiated within 12 h and subsided within 72 h of vaccination. The prevalence of SEs after the first dose of Sputnik V was higher among those aged ≤ 31 years (93.3 %) than those aged > 31 years (80.5 %). In the Sputnik V group, the number of SEs experienced after the first dose was higher in women with underlying diseases than those without such diseases. Furthermore, the body mass index of participants with SEs was lower than that of participants without SEs. CONCLUSION: Compared to Sinopharm or Covaxin, the Sputnik V and Oxford-AstraZeneca vaccines were associated with a higher prevalence of SEs, a greater number of SEs per individual, and more severe SEs.

Antibiotics with Antiviral and Anti-Inflammatory Potential Against Covid-19: A Review.

In Covid-19 cases, elderly patients in long-term care facilities, children younger than five years with moderate symptoms, and patients admitted to ICU or with comorbidities are at a high risk of coinfection, as suggested by the evidence. Thus, in these patients, antibiotic therapy based on empirical evidence is necessary. Finding appropriate antimicrobial agents, especially with antiviral and anti-inflammatory properties, is a promising approach to target the virus and its complications, hyper-inflammation, and microorganisms resulting in co-infection. Moreover, indiscriminate use of antibiotics can be accompanied by Clostridioides difficile colitis, the emergence of resistant microorganisms, and adverse drug reactions, particularly kidney damage and QT prolongation. Therefore, rational administration of efficient antibiotics is an important issue. The main objective of the present review is to provide a summary of antibiotics with possible antiviral activity against SARS-CoV-2 and anti-immunomodulatory effects to guide scientists for further research. Besides, the findings can help health professionals in the rational prescription of antibiotics in Covid-19 patients with a high risk of co-infection.

Aspirin versus placebo on estrogen levels in postmenopausal women: a double-blind randomized controlled clinical trial.

BACKGROUND: Estrogen is involved in the pathogenesis of breast and gynecological cancers. Regular use of aspirin reduces estrogen levels. The present study aimed to evaluate the effect of aspirin on estrogen levels in postmenopausal women. METHODS: This double-blind, placebo-controlled parallel-group trial was conducted on postmenopausal women referred to an outpatient clinic at a women's hospital in Tehran. Volunteers were randomly assigned to receive aspirin 100 mg/day or placebo for 6 weeks. Estradiol, sex hormone-binding globulin (SHBG), and testosterone levels at baseline and at the end of the intervention were measured by ELISA. Data were analyzed using SPSS 20, Kolmogorov-Smirnov test, independent samples t-test, and Mann-Whitney U test. RESULTS: Twenty-seven and 28 participants were finally analyzed in the aspirin and placebo groups, respectively. There was no significant difference between the two groups in body mass index (BMI), age, or menopausal years. There was a statistically significant difference (p = 0.002) in the amount of  change in estradiol levels of the intervention group (median=- 3.5 pg/ml) compared to the control group (median=1.5 pg/ml). In contrast, there were no significant differences between the two groups regarding testosterone and SHBG levels (p = 0.58, p = 0.32). CONCLUSIONS: Since low doses of aspirin may decrease estradiol levels, it could be considered a promising adjunctive therapeutic candidate in postmenopausal women to decrease BC incidence. However, further studies with larger sample sizes, measurements of estrogen levels and its related compounds in different time points accompanied by long-term follow-ups are needed to better elucidate the potential mechanisms by which nonsteroidal anti-inflammatory drugs (NSAIDs) negatively affect breast cancer.

Can betamethasone prevent Nicolau syndrome when coadministered with penicillin? A case report.

We present a 33-year-old female patient with Nicolau syndrome (NS) who received one injection of benzathine penicillin and one injection of betamethasone to the right buttock, and one injection of benzathine penicillin to the left. NS was seen only in the left buttock, where it was intramuscularly injected with penicillin benzathine alone.

Association between medication adherence and health-related quality of life in patients with chronic obstructive pulmonary disease.

BACKGROUND: Chronic Obstructive Pulmonary Disease (COPD) is one of the prominent cause of mortality worldwide. Nowadays, the level of medication adherence in COPD patients is very low, which reduces the clinical therapeutic effects. The purpose of the present study is to investigate the relationship between medication adherence and Health-Related Quality of Life (HRQoL) in COPD patients referred to the pulmonologist's office. METHODS: This observational study was performed on 100 COPD outpatient cases. Each patient was interviewed to answer questionnaires regarding demographic and clinical information. To assess quality of life, health status, and severity of dyspnea, the St George's Respiratory Questionnaire - COPD-Specific Version (SGRQ-C), COPD Assessment Test (CAT), and Modified British Medical Research Council (mMRC) questionnaires were used, respectively. Persian version of the Morisky Medication Adherence Scale (MMAS-8-Item) was used to measure medication adherence. To determine the adherence predictors, an ordinal logistic regression analysis was performed. RESULTS: Out of 100 patients with mean (±SD) age of 61.35 (±10.79) years, 74% had medium and high medication adherence. In the final ordinal logistic model, quality of life, health status, and education level found to have positive effect on medication adherence while polypharmacy had negative effect. We did not find any significant association between age, gender, Body Mass Index (BMI), and other variables with medication adherence. CONCLUSIONS: Patients with high quality of life are more adherent to their medications. Furthermore, patients who have polypharmacy, tend to have less adherence to their medications.

Characteristics of gastric precancerous conditions and Helicobacter pylori infection among dyspeptic patients in north-eastern Iran: is endoscopic biopsy and histopathological assessment necessary?

BACKGROUND: Early detection and appropriate treatment of precancerous, mucosal changes could significantly decrease the prevalence of life-threatening gastric cancer. Biopsy of the normal-appearing mucosa to detect Helicobacter pylori and these conditions is not routinely obtained. This study assesses the prevalence and characteristics of H. pylori infection and precancerous conditions in a group of patients suffering from chronic dyspepsia who were subjected to gastric endoscopy and biopsy mapping. METHODS: This cross-sectional study included dyspeptic patients, not previously treated for H. pylori, undergoing esophagogastroduodenoscopy (EGD) with their gastric endoscopic biopsies obtained for examination for evidence of H. pylori infection and precancerous conditions. Demographic and clinical data on the gender, smoking, opium addiction, alcohol consumption, medication with aspirin, corticosteroids and non-steroidal anti-inflammatory drugs (NSAIDs) and family history of cancer were collected by interviewing the patients and evaluating their health records. The cohort examined consisted of 585 patients with a mean (SD) age of 48.0 (14.46) years, 397 (67.9%) of whom were women. RESULTS: H. pylori infection was identified in 469 patients (80.2%) with the highest prevalence (84.2%) in those aged 40-60 years. Opium addiction correlated with a higher a H. pylori infection rate, while alcohol consumption was associated with a lower rate by Odds Ratio 1.98 (95% CI 1.11-3.52) and 0.49 (95% CI 0.26-0.92), respectively. The prevalence of intestinal metaplasia, gastric atrophy and gastric dysplasia was 15.2, 12.6 and 7.9%, respectively. Increased age, positive H. pylori infection, endoscopic abnormal findings and opium addiction showed a statistically significant association with all precancerous conditions, while NSAID consumption was negatively associated with precancerous conditions. For 121 patients (20.7% of all), the EGD examination revealed normal gastric mucosa, however, for more than half (68/121, 56.2%) of these patients, the histological evaluation showed H. pylori infection, and also signs of atrophic mucosa, intestinal metaplasia and dysplasia in 1.7, 4.1 and 1.7%, respectively. CONCLUSION: EGD with gastric biopsy mapping should be performed even in the presence of normal-appearing mucosa, especially in dyspeptic patients older than 40 years with opium addiction in north-eastern Iran. Owing to the high prevalence of precancerous conditions and H. pylori infection among patients with dyspepsia in parts of Iran, large-scale national screening in this country should be beneficial.

Job satisfaction and the factors affecting satisfaction in nurse educators: A systematic review.

OBJECTIVES: The present study seeks to answer the following two questions: Are nurse educators satisfied with their job? What are the factors affecting job satisfaction in nurse educators? BACKGROUND: Nurse educators' job satisfaction has a significant role in the efficiency and performance of nursing schools. Identifying the factors affecting job satisfaction in nurse educators is essential to improving their quality of work and ultimately training efficient students and nurses. EVALUATION: The present systematic review searched databases including PubMed, Medline, Cochrane Library, Scopus, Web of Science, Science Direct, ProQuest, Google Scholar and SID for articles published up to April 24, 2018, using keywords including Nurse Teachers, Nurse Faculty, Academic Nurses, Nurse Educators, Dis/Satisfaction, Work, Career, Professional, Practice and Job. Of the total of 971 articles extracted, only 74 remained for the final analysis after the qualitative assessment. KEY ISSUE: The articles included in the analysis investigated the relationship between job satisfaction and its contributing factors rather than providing an accurate report on job satisfaction. Nonetheless, a number of the articles had reported fairly to very favorable levels of job satisfaction. The factors affecting nurse educators' job satisfaction were categorized into six levels, including personal, organizational, managerial, academic, professional and economic levels. CONCLUSION: Although job satisfaction was reported relatively well in the nurse educators, this condition depends on several indices. The lack of positive steps toward job satisfaction in nurse educators leads to destructive behaviors and turnover intentions; meanwhile, it is satisfied educators who can train competent nurses.

Comparing the Efficacy of 8 Weeks Treatment of Cipram® and its Generic Citalopram in Patients With Mixed Anxiety-Depressive Disorder.

BACKGROUND: Patients with mixed anxiety-depressive disorder (MADD) suffer both anxiety and depression. Antidepressants, especially, selective serotonin reuptake inhibitors are among agents of choice for treating this condition. OBJECTIVES: This study compared the efficacy of Cipram® with its generic, citalopram. PATIENTS AND METHODS: Forty adult outpatients (between 18 to 55 years of age) with a diagnosis of MADD who met the trial criteria, entered this double-blind, randomized study. Subjects were assigned to receive either generic citalopram or Cipram® for 8 weeks. Hamilton Rating Scale for Depression (HAM-D) and Hamilton Rating Scale for Anxiety (HAM-A) were utilized to assess depression and anxiety at baseline, weeks 4 and 8 of the study. Statistical analysis was performed using SPSS 14.0. RESULTS: Twenty patients received citalopram (mean dosages of 22 mg/day during the first 4 weeks and 33 mg/day during weeks 4 to 8) and 20 received Cipram® (mean dosages of 22 mg/day during the first 4 weeks and 29 mg/day during weeks 4 to 8). Both treatments were noted to be effective in improving the symptoms of MADD at weeks 4 and 8. The mean differences of HAM-D and HAM-A between Citalopram and Cipram® groups were significantly different at the end of week 4 (HAM-D: P = 0.038, HAM-A: P = 0.025), but not at the end of week 8 (HAM-D: P = 0.239, HAM-A: P = 0.204). Both medications were tolerated well by the patients. CONCLUSIONS: This study suggests that the efficacy of citalopram is similar to that of Cipram® in the treatment of MADD after 8 weeks. Meanwhile, Cipram® may reduce depression and anxiety quicker than its generic, citalopram.

Effectiveness of regular versus glargine insulin in stable critical care patients receiving parenteral nutrition: a randomized controlled trial.

STUDY OBJECTIVE: To compare the effectiveness and safety of two glycemic control regimens in stable critical care patients receiving parenteral nutrition (PN). DESIGN: Prospective, randomized open-label clinical trial. METHODS: Eligible postoperative critical care patients in the ICU began PN on the first to the seventh day of ICU admission. The PN admixture included regular insulin, in doses sufficient to maintain 3 or more goal blood glucose (BG) levels between 110 and 180 mg/dl. After 3 to 5 days of PN containing regular insulin, patients were randomized to 3 more days of regular insulin at the same dose or 80% of their total daily regular insulin dose provided in PN solution as glargine insulin. Capillary BG monitoring was performed every 6 hours. RESULTS: Twenty one patients were randomized to each treatment group. Median APACHE II scores were not significantly different between the two groups within the first 24-hour of ICU admission. There were no significant differences between the two groups at day 3 for mean daily dextrose (306.9 ± 46.2 vs. 305.2 ± 52.2 g; p=0.913) or insulin (18.3 ± 8.8 vs. 19.5 ± 10.0 units; p=0.696) doses. The percentage of BG values in the goal (110-180 mg/dl), hyperglycemic (> 180 mg/dl), and hypoglycemic (< 70 mg/dl) BG levels were similar between the two groups (69.0% vs. 66.7%, p=0.567; 11.9% vs. 11.1%, p=0.780; 0% vs. 1.6%, p=0.124, respectively). Mean daily BG levels were not significantly different between the two groups on each of the 3 study days (day 1: 140 ± 20 vs. 131 ± 25 mg/dl, p=0.194; day 2: 136 ± 20 vs. 140 ± 18 mg/dl, p=0.498; day 3: 142 ± 15 vs. 140 ± 19 mg/dl; p=0.741). CONCLUSION: These data suggest that, compared with regular insulin added to PN, glargine insulin results in similar glycemic control and rates of hyperglycemia and hypoglycemia in stable critical care patients.

Clinical and biochemical analysis of acute paint thinner intoxication in adults: a retrospective descriptive study.

CONTEXT: Paint thinner contains a mixture of various aromatic hydrocarbons. A few studies have reported biochemical abnormalities and clinical symptoms of paint thinner intoxication among adult patients. OBJECTIVE: We aimed to design a retrospective descriptive study to evaluate clinical and laboratory biochemistry abnormalities due to paint thinner intoxication among adult patients. METHODS: Data were obtained by using questionnaires from paint thinner-intoxicated patients recruited at the Loghman-Hakim General Teaching Hospital Poison Center. RESULTS: Clinical and paraclinical data from a total of 37 patients, 24 males (64.86%) and 13 females (35.14%) with the mean age of 34.35 ± 14.15 years and mode of 22 years, was obtained and analyzed. Patients' ages ranged between 15 and 70 years. The estimated mean consumed dose was 246.70 ± 390.72 ml with a mode of 60 ml (range of 1-1500 ml). Nausea, vomiting, asthma, sore throat, stomach ache, drowsiness, dizziness, agitation, cough and diarrhea were the most frequent clinical features, respectively. Reported tissue damage biomarkers were alkaline phosphatase (ALP, 233.84 ± 122.06) and lactate dehydrogenase enzymes (LDH, 749.33 ± 471.03 IU/l). They reflected development of liver and pulmonary toxicities. Arterial blood gas (ABG) showed acidosis without hypoxia in adult paint thinner-intoxicated patients. DISCUSSION AND CONCLUSION: Focusing on biochemical abnormalities and clinical toxicity symptoms is essential for screening organs in paint thinner toxicity. In addition, they provide good information for physicians/clinical toxicologists to perform appropriate conservative treatments in adult paint thinner-intoxicated patients.

Serum cystatin C as a marker of renal function in critically ill patients with normal serum creatinine.

BACKGROUND: Serum creatinine as a classic marker of renal function has several limitations in the detection of renal dysfunction. OBJECTIVES: This study assessed the validity of serum cystatin C as a marker of renal function in critically ill patients with normal serum creatinine. PATIENTS AND METHODS: Eighty adult patients referred to intensive care units with serum creatinine levels < 1.5 mg/dL and without hemodynamic instability were chosen and their serum creatinine and cystatin C levels were measured. A 24-hour urine sample was collected to calculate creatinine clearance (Ccr). Renal dysfunction was defined as Ccr < 80 mL/min/1.73 m(2). RESULTS: There were significant correlations between measured Ccr and 1/serum creatinine (R = 0.51, P < 0.001) and 1/serum cystatin C (R = 0.25, P = 0.028). The difference between false negative rates of serum creatinine (93.33%) and cystatin C (80%) in the detection of renal dysfunction was significant (P = 0.032). Receiver operating characteristic curve analysis illustrated that area under the curve of serum creatinine and cystatin C for detecting renal dysfunction were 0.711 and 0.607, respectively; however, this difference was not significant (P = 0.222). CONCLUSIONS: Our data demonstrated that serum cystatin C is not superior to serum creatinine in the early detection of renal dysfunction in critically ill patients.

Increasing the number of adverse drug reactions reporting: the role of clinical pharmacy residents.

Detection of adverse drug reactions (ADRs) in hospitals provides an important measure of the burden of drug related morbidity on the healthcare system. Spontaneous reporting of ADRs is scare and several obstacles to such reporting have been identified formerly. This study aimed to determine the role of clinical pharmacy residents in ADR reporting within a hospital setting. Clinical pharmacy residents were trained to report all suspected ADRs through ADR-reporting yellow cards. The incidence, pattern, seriousness, and preventability of the reported ADRs were analyzed. During the period of 12 months, for 8559 patients, 202 ADR reports were received. The most frequently reported reactions were due to anti-infective agents (38.38%). Rifampin accounted for the highest number of the reported ADRs among anti-infective agents. The gastro-intestinal system was the most frequently affected system (21.56%) of all reactions. Fifty four of the ADRs were reported as serious reactions. Eighteen of the ADRs were classified as preventable. Clinical pharmacy residents' involvement in the ADR reporting program could improve the ADR reporting system.
