The purpose of this systematic review and meta-analysis was to investigate the efficacy of propolis on glycemic indices in type 2 diabetic patients.

Web of science (ISI), Embase, Scopus and PubMed were systematically searched to find randomized controlled trials (RCTs) assessing the effects of propolis intake on glycemic controls in type 2 diabetic patients, from inception up to September 1, 2020. A random-effects model was used to pool weighted mean difference (WMD). Meta-regression was performed to detect the potential sources of inter-study heterogeneity.

Seven trials were included in the meta-analysis. Compared to controls, propolis intake significantly improved serum fasting blood sugar (FBS) (WMD = −13.62 mg/dl, 95% CI = [−23.04, −4.20], P = 0.005, I2 = 58.5%) and hemoglobin A1C (HbA1c) (WMD = −0.52%, 95% CI = [−0.86, −0.18], P = 0.002, I2 = 64.0%). In contrast, receiving propolis did not change serum insulin (WMD = −1.46 (uIU/ml), 95% CI = [−2.94, 0.02], P = 0.05, I2 = 75.0%) and homeostatic model assessment for insulin resistance (HOMA-IR) (WMD = −0.98 (%), 95% CI = [−2.00, 0.04], P = 0.06, I2 = 82.3%) compared to controls.

The present meta-analysis demonstrated that propolis intake significantly reduces serum FBS and HbA1c in diabetic patients but does not alter serum insulin and HOMA-IR. Further large-scale RCT’s are needed to approve these effects.

The purpose of this paper is to empirically investigate the impact of organizational intellectual capital (IC) components on absorptive capacity (ACAP) such as potential absorptive capacity (PACAP) and realized absorptive capacity (RACAP). Furthermore, it attempts to investigate the mechanism through which PACAP and RACAP jointly influence innovation strategies (i.e.) exploitative and exploratory innovations.

This is an explanatory research using a deductive approach. This study uses survey data from 184 manufacturing export firms analyzed through partial least squares structural equation modelling.

The results have found that the cognitive and social capital of a firm positively affects PACAP and RACAP, whereas relational capital has a significant effect on RACAP. Moreover, the study reveals that both potential and realized absorptive capacities considerably lead to the development of organizational exploitative and exploratory innovation strategies.

The research focused on two driving factors, i.e. IC components and ACAP dimensions, and overlooked how each component of IC and ACAP influences ambidextrous innovative strategy.

Providing managers with insights about the critical role of developing IC to facilitate the transfer and exchange of crucial absorptive capacity necessary for ambidextrous innovative strategy.

This study makes a significant contribution to the existing literature by highlighting the importance of ACAP and provides useful insights for firms in developing economies to improve their exploitative and exploratory innovation capability. This study likewise reveals the significance of the four dimensions of IC, which can facilitate bringing in knowledge from developing economies.

The regulation defines patients’ rights as a reflection of fundamental human rights in the field of medicine and incorporates all elements of patients’ rights accepted in international texts. Hence, the purpose of this paper is to investigate the relationship between patients’ safety, medical errors and patients’ safety rights with patients’ security feeling in selected hospitals of Mazandaran Province, Iran.

This descriptive cross-sectional study was conducted in selected hospitals of Mazandaran Province in public, social and private hospitals in 2016. In total, 1,083 patients were randomly selected for the study. The developed tool (questionnaire) was used for data collection. Questionnaire validity was verified through experts and its reliability was confirmed by Cronbach’s α coefficient (95 percent). Data were analyzed through multiple regressions by SPSS software (version 21).

The findings of this paper showed that the mean (standard deviation) medical error, patient’s safety, patient’s rights and patient’s security feeling were 2.50±0.61, 2.22±0.67, 2.11±0.68 and 2.73±0.63, respectively. Correlation testing results showed that medical error, patient’s safety and patient’s rights simultaneously had a significant relation with patient’s security feeling in the selected hospitals (p<0.05).

A simultaneous correlation between patient’s safety, patient’s rights and medical errors with patient’s security feeling in social security hospitals was higher than other hospitals. Hence, the authorities and officials of hospitals and healthcare centers were advised to make effective attempts to perceive the patient’s safety, medical errors and patient’s rights to improve the patient’s security feeling and calmness and also to make better decisions to promote the healthcare and therapeutic services.
