The World Health Organization (WHO) has introduced palliative care as a way to improve the quality of life of patients with incurable diseases and their families. This care begins with the diagnosis of the disease, and continues throughout the illness (1). Palliative care improves the quality of life of patients with life-threatening diseases and their families. Its purpose is to relieve suffering through the identification, evaluation, and relief of pain and other physical, psychosocial and spiritual problems (2).
Palliative care is required for many diseases. According to reports, every year about 40 million people in the world need palliative care, but only 14% of them receive it, of whom 78% live in low-income or middle-income countries. According to the World Health Organization, patients who require palliative care services, suffer from cardiovascular diseases (38.5%), cancer (34%), chronic pulmonary diseases (10.3%), AIDS (5.7%), and diabetes (4.6%). Other patients with diseases, such as dementia, kidney failure, multiple sclerosis, Parkinson’s disease, rheumatoid arthritis, neurological diseases, congenital anomalies, and resistant tuberculosis may also need palliative care services (1). Palliative care can be offered to patients through various models, including hospital-based palliative care, hospice-based palliative care and home-based palliative care (3). Studies have shown that home-based palliative care has a very beneficial effect on the physical, mental, psychological, social and economic dimensions of patient’s life, and reduces the cost of health system, shortens the length of hospitalization, reduces hospital complications and prevents hospital readmission (4-6). This type of care also facilitates the continuity of post-discharge care and helps patient to easily benefit from the facilities of different centers (7). On the other hand, most people prefer to receive care at their homes with their families (8). Studies have shown that home-based palliative care is clinically and economically effective and leads to the satisfaction of patients and their families. Also, the World Health Organization in 2014 has introduced home-based palliative care as one of the main elements of the health systems all around the world (1). However, reports indicate that many countries in the world do not have palliative care programs in their health care system (7), and the lack of government support for palliative care services, lack of prepared professional staff to provide palliative services, limitation in access to narcotic analgesics, resource constraints, lack of policy-makers’ familiarity with palliative medicine, the negative attitude of society towards palliative care and socio-cultural issues have been mentioned as barriers to palliative care in the world (1, 9,10).
Iran’s health system is faced with increasing number of chronic patients and shortages of manpower and ICU beds in health centers. Most patients with life-threatening diseases in Iran are frequently admitted to hospital during the last days of their lives. Despite the shortage of hospital beds, especially in the critical care units, these patients occupy these beds and receive specialized medications until the end of their lives and eventually many of these patients die on ICU beds in hospital (11). While in many cases, hospitalization of incurable patients in critical care units does not have any positive effects on patients’ recovery, and is considered a futile care (12), which increases the costs of health system, poses financial burden on patient’s family, and leads to dissatisfaction and work burnout in healthcare staff (13). On the other hand, many of these patients prefer to spend the last days of their lives at home with their family and be in close contact with their relatives. Evidence suggests that palliative care in Iran is only offered in isolated and limited centers. Most patients are deprived of this kind of care, and home-based palliative care does not have any place in Iran’s health system (14). Patients with incurable conditions who require palliative care services are lost in the system, and in most cases do not receive proper and timely services they need (15). Also, the traditional attitude of healthcare staff towards the management of incurable conditions, the lack of transparency in the protection of healthcare staff against discontinuation of unnecessary treatments or unreasonable expectations of patients and their families, as well as social and cultural differences are barriers to the promotion of palliative care in Iranian society. Another problem in providing home-based palliative care services is the defect in the payment process and insurance coverage of end-of-life patients (16,17). Therefore, given the high prevalence of chronic and incurable illnesses, the increasing number of elderly population, limited critical care beds, shortages of human resources, limited financial resources and equipment in health centers, and taking into account the benefits of home-based palliative care, healthcare system authorities should consider this care method to be one of the important priorities of the health system so that patients can maintain their quality of life and also experience peace during the last days of their lives. Considering the limited research in this field, further research is required on the management of various dimensions of home-based palliative care in order to provide suitable models for the provision of home-based palliative care services in Iran.

One of the important issues that affects the quality of hemodialysis is recirculation. Some researchers have suggested that the direction and distance of needle cannulation can affect the amount of recirculation. Therefore, this study aimed to investigate the effect of direction and distance of needle cannulation on recirculating of arteriovenous fistula in hemodialysis patients. Methods & Materials: This clinical trial was performed on patients referred to the dialysis ward of Kamkar-Arabnia hospital affiliated to Qom University of Medical Sciences in 2016. The amount of recirculation was measured in 22 patients by urea based method, in four consecutive sessions. In each session, the distance and direction of the needles were three centimeters in opposite direction, three centimeters in same direction, six centimeters in opposite direction, and six centimeters in same direction. Data were analyzed using Stata and GEE test. The average age of participants was 53(16±0.75) years. In 41 dialysis cases (out of 88), the amount of recirculation was higher than 10%. The odds ratio for more than 10% recirculation for a distance of three centimeters compared to six centimeters was 2.05 (1.07-3.93) and for same direction compared to opposite direction was 1.98 (1.03-3.78). The results of this study showed that the insertion of needles at a distance of six centimeters in opposite position had the lowest chance of recirculation. Therefore, the attention to proper insertion of needles can be effective in reducing recirculation and increasing the quality of dialysis.

Couples face many problems in pregnancies following In vitro fertilization (IVF) compared to normal pregnancies. The majority of studies have focused on women, and men have received less attention. So, this study aimed to explore the perceptions of men awaiting the first child following IVF. Methods & Materials: This qualitative study was carried out in Shahid Motahari hospital in Urmia during 2017-2018. Data were collected using 19 individual in-depth semi-structured interviews. Participants were selected among men whose wives got pregnant by IVF, through purposeful sampling, until data saturation was reached. Data were analyzed through conventional content analysis approach using the MAXQDA software version 10. Four categories of "hope and fear of treatment outcome", "fear of social stigma", "financial concern", and "need for participation and training" were emerged from data analysis. Men whose wives got pregnant through IVF have expectations and needs that must be addressed. On the one hand, the men are concerned about the social stigma of infertility and donation, the outcome of treatment, and the economic problems of treatment, and on the other hand they expect to be involved in the process of treatment and prenatal care.

Anxiety is one of the most common psychiatric disorders in the family of patients with traumatic brain injury. This study aimed to determine the effect of providing information about the patient’s condition on the anxiety level of the family members of hospitalized patients with traumatic brain injury. Methods & Materials: This quasi-experimental study was conducted on 90 family members of traumatic brain injury patients admitted to Shahid Bahonar hospital in Kerman in 2016. The participants were selected by the consecutive sampling method and were assigned to intervention and control groups. In the intervention, the participants were informed by the nurse about changes in the patient’s condition during the first three days of admission to intensive care unit. During this period, the control received routine care. Data collection tool was the Spielberger anxiety inventory. Independent and paired t-test were used to compare the mean scores of anxiety using the SPSS software version 16. There was no statistically significant difference in the mean scores of overt, covert and general anxiety between the two groups before the intervention (P>0.05). However, after the intervention in the experimental group, the mean scores of overt anxiety (45.51±7.26), covert anxiety (45.42±6.51) and general anxiety (90.93±12.72) decreased (P<0.05) compared to the mean scores of overt anxiety (49.22±9.42), covert anxiety (49.02±9.15) and general anxiety (98.24±17.67) in the control group. Providing planned information on changes in the condition of hospitalized patients with traumatic brain injury can reduce the anxiety of family members of these patients.

Needlestick injury is an occupational risk. Medical university students are more likely to prone to this kind of injury in comparison to other students due to their limited knowledge, skills and clinical experiences. The present systematic review and meta-analysis aimed to estimate the prevalence of needlestick injury in medical university students in Iran. Methods & Materials: In the present systematic review and meta-analysis, 22 papers written by Iranian researchers published in Persian and English, were included without time limitations. The articles were found by searching Iranian (Magiran, Scientific Information Databases (SID) and IranMedex) and international (Google Scholar, Web of Science, PubMed and Scopus) databases. Data were analyzed using meta-analysis method and the random effects model. The overall prevalence of needlestick injury among medical university students was 47% (95% CI: 39-55). There was no relationship between vaccine coverage, age of samples, and sample size with the prevalence of needlestick injury. The prevalence of needlestick injuries significantly decreased with increase in the publication years of articles (P=0.03), and significantly increased (P=0.049) with lack of reporting. Considering the high prevalence of needlestick injury in the students of medical sciences universities, it is of great necessity to design educational programs focusing on the proper use of sharp and cutting instruments as well as the importance of reporting and modifying professional behavior such as avoiding the reinsertion of needles in order to reduce the incidence rate of needlestick injuries.

Empowerment is a dynamic, positive, interactive and social process, leading to the improvement of quality of life (QOL) in patients with chronic disease. The purpose of this systematic review and meta-analysis was to determine the effect of family-centered empowerment model (FCEM) on QOL in adults with chronic diseases. Methods & Materials: By searching FCEM in Persian databases including SID, MagIran, IranMedex, IranDoc, and googlescholar, Scopus, Pubmed, Web-of-science, Proquest, and Sciencedirect, all relevant studies were extracted. The methodological quality of the papers was examined using Cochrane-risk-of-bias. Data analysis was carried out through the random effects model and heterogeneity by I2 index. The data were analyzed using the STATA software version 11.0. Of the 647 initial studies, only 8 studies examined the effect of FCEM on the QOL in adult patients using SF-36. The pooled standardized mean difference of the 8-dimensions of QOL included: social-functioning (1.781), Physical role limitation (1.416), bodily pain (0.987), general health (1.352), social functioning (1.010), general health (1.122), emotional role limitation (0.656), and vitality (1.361). The implementation of FCEM had a significant effect on the 8-dimensions of QOL based on the SF-36 questionnaire. The implementation of FCEM is recommended in order to improve the QOL of adult patients with chronic disease.

Depression is common among cardiac patients, especially patients with heart failure and leads to a poor prognosis. This study aimed to assess the effect of exercise on depressive symptoms in patients with heart failure, attending the Cardiac Rehabilitation Center.
Methods & Materials: In this clinical trial, 60 patients with NYHA class II and III heart failure who referred to the Cardiac Rehabilitation Center of Shafa Hospital affiliated to Kerman University of Medical Sciences in 2015 were randomly assigned into two groups of 30 patients. Subjects in the intervention group participated in a supervised 8-week exercise program, 3 days per week, while those in the control group only received standard routine care. Data were collected before and after the intervention by the demographic form and the Personal Health Questionnaire Depression Scale (PHQ-8). Data analysis was done by Chi-Square, Wilcoxon, Mann-Whitney U and Nonparametric ANCOVA tests using the SPSS version 21 and R software. The two groups were homogeneous in terms of depression score before the intervention. The median and interquartile range of the score of depression were 10 (5.25) in the control group and 8.5 (9.25) in the intervention group which showed a significant difference (P=0.042). By adjusting the variables of the duration of the disease and the pre-test scores of depression symptoms by non-parametric covariance test, the difference between the two groups was also significant. Exercise can reduce depressive symptoms in patients with heart failure.

Insufficient health literacy is a major barrier to self-care in patients with heart failure. The purpose of this study was to determine relationship between health literacy and self-care behaviors in patients with heart failure. Methods & Materials: In this correlational study, 100 patients with heart failure who were referred to teaching hospitals in Qom were selected through the convenience sampling method in 2017. The data collection tools were the heart failure-specific health literacy scale, the self-care of heart failure index (SCHFI) and the hospital anxiety and depression scale (HADS). Data were analyzed using descriptive statistics, the Pearson’s correlation coefficient and multiple liner regression analysis on the SPSS software version 16. More than half of the patients had a moderate level of self-care. The highest and lowest health literacy scores were respectively related to critical health literacy (10.47±2.56) and functional health literacy (9.14±3.74). The result of multiple regression analysis showed that only functional health literacy was a better predictor of self-care behaviors in patients with heart failure (β=0.30, P=0.014). The findings showed that functional health literacy was an important predictor of self-care behaviors among patients with heart failure. It seems necessary to design effective interventions in order to improve patients’ skills for analyzing functional information and decision making in self-care.
