● Evidence-based strategies recommend the application of a care package to reduce central catheter infection in NICUs. 
● The present study investigated the effects of applying a care package on the incidence of infection and the shelf life of central peripheral venous catheters, in the premature infants admitted to the NICU. 
● The obtained results indicated that the standard guideline training of nurses could reduce the incidence of central venous catheter infection in infants.
Plain Language Summary 
Low-birth-weight infants often require intravenous access for more than six days. Therefore, a central peripheral venous catheter is considered to be an acceptable alternative to provide long-term access to the vein with few complications and no restrictions on any injections. The nurses who are involved in the implantation of central peripheral venous catheters in infants and children must have sufficient knowledge and experience in the care of this population. The present study aimed to assess the effects of using a care package on the incidence of infections and the shelf life of central peripheral venous catheterization in the premature infants admitted to the NICUs. According to the obtained results, the standard guideline training of nurses reduces the incidence of central venous catheter infection in infants.

● The present scoping review provided a comprehensive view of nursing competency in Iran. Also, most of the evidence was obtained from primary quantitative investigations.
● Among the studies, 26% evaluated competency through self-assessment and reported it to be at a desirable level.
 ● Based on the findings, a nurse is expected to have moral, clinical and special, cultural, emotional, and motivational competency. 
● The relationships between clinical competency and other variables were explored in several studies.
● Effective strategies for the promotion of clinical competency are explained and summarized.

● Aging leads to changes in many human capabilities. 
● Technology is one of the ways that help older adults to preserve independence. 
● A review of the literature showed that there is no tool in Iran to measure the use of technology at home by older adults.
● This study developed the “Older Adults’ Technology Use at Home Scale” and evaluated its psychometric properties in an Iranian context.
Plain Language Summary 
The aging process commonly decreases the physical and mental functions of older adults. However, the use of technology can improve the cognitive, sensory, and motor functions of older adults. This study discusses the development of a scale that measures the use of technology at home by older adults, in an Iranian context. Study results showed that the older adults’ technology use at home scale is a valid and reliable tool for the measurement of the use of technology by older adults at home, in daily life.

● Marital satisfaction is a basic necessity for a lasting married life. 
● One of the main causes of divorce and separation is the lack of satisfaction and happiness in living together.
● In this study, researchers examined the role of mate selection in the satisfaction of marriage by examining the narratives of couples who have been married for more than a decade. 
● Interviews resulted in four main themes, including spouse personality traits, shared religious beliefs, shared socioeconomic positions, and mutual respect and understanding. 
Plain Language Summary 
Mate selection is one of the first requirements for establishing a marital relationship in both Western and non-Western societies. Research shows that lasting marital satisfaction depends on the similarity between a couple’s values, culture, religion, personality traits, and economic status. This research focused on mate selection as one of the main factors associated with lasting marital satisfaction. The analysis of the couples’ comments showed that the “mate selection” has the main role in their lasting marital satisfaction. Interviews led to four main subjects: spouse personality traits, shared religious beliefs, shared socioeconomic positions, and mutual respect and understanding. The findings of this study help counselors, couples’ therapists, mental health professionals, psychiatric nurses, and midwifery consultants prepare couples for premarital programs.

● Schema therapy and emotional self-regulation therapy effectively improved the components of marital conflict in women.
● Schema therapy and emotional self-regulation therapy were able to reduce emotional reactions in women.
● Schema therapy and emotional self-regulation therapy improved relations with the spouse’s family and friends.
Plain Language Summary 
Marital conflicts gradually lead to a serious dispute in values and life goals. In contrast, efficient conflict management prevents the failure of the marital relationship and shows the couple how to effectively deal with problems to minimize adverse impacts on their marital relations. Thus, marital conflicts should be resolved by adopting appropriate treatment methods to avoid subsequent problems. In this regard, schema therapy and emotional self-regulation therapy are among the most important intervention programs; applying these interventions, this study suggested the following conclusions. Women undergoing schema therapy and emotional self-regulation therapy can control their emotions and improve their marital relations by reducing marital conflicts. Also, these two intervention programs can be used to improve the components of marital conflict in women confronting marital conflicts.

● This study showed the existence of ageism in older adult care.
● The level of ageism was associated with age, gender, work experience, and the ward in which the nurses worked.
● The results of the study have important implications for further research and suggest the development of interventions to decrease ageism in practice.
Plain Language Summary 
Ageism is defined as discrimination due to age in the provision of care to the elderly. Evidence shows that caregivers are unaware of their discriminatory treatment of the elderly. The evaluation of care by the care provider system positively impacts the acceptance and provision of qualified caregiving to older people. Thus, it is important to determine the status of ageism in caring for elderly patients, in hospitals, in the Iranian context. Nurses in this study showed a discriminatory view in providing care for the elderly. Moreover, the discriminatory view was related to the age, gender, work experience, and the ward in which the nurses worked.
