Effect of acupressure at the BL67 spot on the spontaneous rotation of fetus with breech presentation: A randomized controlled trial.

BACKGROUND: Breech is a common fetal presentation in preterm pregnancies. This study aimed to investigate the effect of acupressure at the BL67 point on the spontaneous rotation of fetus with breech presentation. METHODS: An unblind, two-armed randomized controlled trial was carried out from September 2017 to April 2020. Research participants were 138 pregnant women at 32 to 35 weeks of gestational age that had fetal breech presentation confirmed by ultrasound. They were randomly assigned into intervention and control groups (n=69 in each group). The intervention group received acupressure at the BL67 point on both feet for 10 minutes daily and for two consecutive weeks. The control group received routine care. Demographic and midwifery data questionnaires were used for data collection. RESULTS: The spontaneous rotation of fetus with breech presentation into cephalic was observed in the majority of participants in the intervention group (82.6%) compared to the control group (17.4%) (p<0.001). Statistically significant differences in the fetal presentation at delivery was observed between the groups (84.1% cephalic vs. 18.8% breech, p<0.001). Regarding the type of delivery, cesarean section was reported mostly (85.5%) in the control group compared to the intervention group (21.7%) (p<0.001). However, the first- and fifth-minute Apgar scores of newborns had no statistically significant differences between the groups (p=0.773). CONCLUSION: It is suggested to incorporate acupressure at the BL67 point into the care process for pregnant women to help with the reduction of the rate of cesarean section and avoid its related complications.

Effect of Benson and progressive muscle relaxation techniques on sleep quality after coronary artery bypass graft: A randomized controlled trial.

OBJECTIVE: This study aimed to investigate the effect of Benson relaxation (BR) and progressive muscle relaxation (PMR) techniques on the sleep quality of patients undergoing coronary artery bypass graft (CABG) surgery. METHOD: This study was a three-arm, parallel, randomized controlled trial. 120 patients who underwent CABG surgery at two academic hospitals in an urban area of Iran were randomly allocated into three groups (40 per group): the BR, PMR, and control groups. Patients in the BR and the PMR groups performed relevant exercises twice a day for four weeks. Sleep quality was measured before and immediately after the intervention using Pittsburgh Sleep Quality Index. RESULTS: Within-group comparison in the BR (t = 3.51, p = 0.001) and the PMR (t = 4.58, p < 0.001) group showed that the overall sleep quality showed a significant improvement after the intervention when compared to baseline. The between-group comparison showed that both the BR and PMR groups showed significant improvements in subjective sleep quality (F = 3.75, p = 0.02), habitual sleep efficiency (F = 4.81, p = 0.01), and overall sleep quality (F = 5.53, p = 005) when compared to the control group after the intervention. However, no statistically significant differences were identified among the three study groups in terms of sleep latency, sleep duration, sleep disturbances, sleeping medication, and daytime dysfunction after the intervention (p > 0.05). CONCLUSION: The study showed that a four-week program of both PMR and BR can be effective in the overall improvement of sleep quality in patients following CABG. Further research is required to replicate the findings of the present study.

Airborne Pollens and Their Association with Meteorological Parameters in the Atmosphere of Shiraz, Southwest Iran.

Airborne pollen is considered one of the causative agents of hay fever, allergic rhinitis, conjunctivitis, and asthma. We aimed to investigate airborne pollens in the context of Shiraz located in the southwest of Iran and find their association with meteorological parameters.  The survey was conducted from October 2017 to September 2018, using seven days of volumetric Burkard spore trap, located in the center of the city. A total of 5810 pollen grains/m3 belonging to 15 taxa were identified and recorded. Among them, 73.8% was the tree, while the grass, shrub, and weed constituted 13.56%, 3.5%, and 9.2% of total reported pollens, respectively. The major pollen types were Platanaceae (28.39%), Oleaceae (21.17%), Pinaceae (15.11%), Amaranthaceae (9.29%), and Brassicaceae (8.02%). A higher number of pollen counts and types were recorded in March, followed by September, while it was lower in May. Meteorological parameters were correlated with the monthly pollen counts. Wind speed was found to have a positive correlation with Platanaceae concentration. The significant correlation between pollen concentration and the temperature was positive for Poaceae, Amaranthaceae, and Plantaginaceae and negative for Rosaceae, Oleaceae, and Ulmaceae.  Poaceae and Amaranthaceae were negatively correlated with humidity and positively with Rosaceae, Oleaceae, and Plantaginaceae. A negative correlation was found between rainfall and Poaceae and Amaranthaceae, while Plantaginaceae had a positive correlation with this parameter. The results of this study may be helpful for allergologists in the diagnosis and treatment of airborne allergic disorders due to pollen grains.

Leishmanicidal potentials of Gossypium hirsutum extract and its fractions on Leishmania major in a murine model: parasite burden, gene expression, and histopathological profile.

Introduction. Leishmaniasis is a neglected tropical and subtropical disease caused by over 20 protozoan species.Hypothesis. Treatment of this complex disease with traditional synthetic drugs is a major challenge worldwide. Natural constituents are unique candidates for future therapeutic development.Aim. This study aimed to assess the in vivo anti-leishmanial effect of the Gossypium hirsutum extract, and its fractions compared to the standard drug (Glucantime, MA) in a murine model and explore the mechanism of action.Methodology. Footpads of BALB/c mice were infected with stationary phase promastigotes and treated topically and intraperitoneally with G. hirsutum extract, its fractions, or Glucantime, 4 weeks post-infection. The extract and fractions were prepared using the Soxhlet apparatus with chloroform followed by the column procedure.Results. The crude extract significantly decreased the footpad parasite load and lesion size compared to the untreated control group (P<0.05), as revealed by dilution assay, quantitative real-time PCR, and histopathological analyses. The primary mode of action involved an immunomodulatory role towards the Th1 response in the up-regulation of IFN-γ and IL-12 and the suppression of IL-10 gene expression profiling against cutaneous leishmaniasis caused by Leishmania major.Conclusion. This finding suggests that the extract possesses multiple combinatory effects of diverse bioactive phytochemical compositions that exert its mechanisms of action through agonistic-synergistic interactions. The topical extract formulation could be a suitable and unique candidate for future investigation and pharmacological development. Further studies are crucial to evaluate the therapeutic potentials of the extract alone and in combination with conventional drugs using clinical settings.

Embryonic toxico-pathological effects of meglumine antimoniate using a chick embryo model.

Leishmaniasis is one of the diverse and neglected tropical diseases. Embryo-toxicity of drugs has always been a major concern. Chick embryo is a preclinical model relevant in the assessment of adverse effects of drugs. The current study aimed to assess embryonic histopathological disorders and amniotic fluid biochemical changes following meglumine antimoniate treatment. The alteration of vascular branching pattern in the chick's extra-embryonic membrane and exploration of molecular cues to early embryonic vasculogenesis and angiogenesis were also quantified. Embryonated chicken eggs were treated with 75 or 150 mg/kg of meglumine antimoniate. Embryo malformations, growth retardation and haemorrhages on the external body surfaces were accompanied by histopathological lesions in the brain, kidney, liver and heart in a dose-dependent manner. Significant rise occurred in the biochemical indices of alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase and amylase in the amniotic fluid. Quantification of the extra-embryonic membrane vasculature showed that the anti-angiogenic and anti-vasculogenic effects of the drug were revealed by a significant decrease in fractal dimension value and mean capillary area. The relative expression levels of vascular endothelial growth factor A and vascular endothelial growth factor receptor 2 mRNA also significantly reduced. Concerns of a probable teratogenicity of meglumine antimoniate were established by data presented in this study. It is concluded that tissue lesions, amniotic fluid disturbance, altered early extra-embryonic vascular development and gene expression as well as the consecutive cascade of events, might eventually lead to developmental defects in embryo following meglumine antimoniate treatment. Therefore, the use of meglumine antimoniate during pregnancy should be considered as potentially embryo-toxic. Hence, physicians should be aware of such teratogenic effects and limit the use of this drug during the growing period of the fetus, particularly in rural communities. Further pharmaceutical investigations are crucial for planning future strategies.

A randomized controlled clinical trial evaluating quality of life when using a simple acupressure protocol in women with primary dysmenorrhea.

OBJECTIVE: To evaluate a simple acupressure protocol in LIV3 and LI4 acupoints in women with primary dysmenorrhea. METHODS: This paper reports a randomized, single blinded clinical trial. 90 young women with dysmenorrhea were recruited to three groups to receive 20min acupressure every day in either LIV3 or LI4, or placebo points. Acupressure was timed five days before menstruation for three successive menstrual cycles. On menstruation, each participant completed the Wong Baker faces pain scale, and the quality of life short form -12 (QOL SF-12). RESULTS: Intensity and duration of pain between the three groups in the second and third cycles during the intervention (p<0.05) differed significantly. Significant differences were seen in all domains of QOL except for mental health (p=0.4), general health (p=0.7) and mental subscale component (p=0.12) in the second cycle, and mental health (p=0.9), and mental subscale component (p=0.14) in the third cycle. CONCLUSION: Performing the simple acupressure protocol is an effective method to decrease the intensity and duration of dysmenorrhea, and improve the QOL.

The effect of hydroalcoholic extract of Achillea eriophora DC. on blood pressure of anaesthetized male rat.

Achillea eriophora (Asteraceae) is a medicinal plant commonly used in Iran. This study was performed to determine the cardiovascular effects of hydroethanolic extract of A. eriophora (HEAE) and the underlying mechanisms in anaesthetized rats. The acute effects of intravenous (i.v.) administration of different doses of HEAE (40, 50, 60, 80 mg/kg), and its probable interaction with cholinergic and nitrergic systems were investigated in the presence of ACh and NOS blocker (L-NAME) as well as ethanol (HEAE solvent in sham group). Intravenous administration of different doses of HEAE induced hypotension. HEAE (60 mg/kg) significantly reduced mean arterial blood pressure (MAP), systolic arterial blood pressure (SBP) and diastolic arterial blood pressure (DBP) compared to control rats that treated with ethanol only, but no change in heart rate (HR) was seen in both groups. The results showed significant decrease in MAP, SBP, DBP and increase of HR in the presence of HEAE plus ACh (10 µg/kg) compared to when ACh was injected alone. Finally i.v. administration of HEAE, significantly reduced MAP and DBP in L-NAME (5 mg/kg) treated animals, while bradycardic responses to L-NAME were not significantly changed by HEAE. It can be concluded that Achillea eriophora induced hypotensive effect via lowering total peripheral resistance and cardiac output that may be synergist with cholinergic and independent of nitrergic system.

Ethnobotanical study of medicinal plants of Sirjan in Kerman Province, Iran.

ETHNOPHARMACOLOGICAL RELEVANCE: From ancient time human beings have used different plants, animals and minerals to prevent and treat various diseases. In this respect, plants have been of particular importance. Ethnobotany is the science of reviewing how indigenous people and local tribes have used their regional plants for particular purposes such as treating diseases in the past. The information gathered from such studies can help to improve national health systems and even lead to the discovery of new medicines. Keeping this in mind, in this study a survey of Sirjan area ethnobotany was conducted during 2011-2012. MATERIALS AND METHODS: At the beginning, thirteen local people were interviewed about their region׳s medicinal plants and their consumptions. These plants were collected and identified using identification keys. The data collected was analyzed using quantitative value indices FIC, RFC and CI. RESULT: Many plants collected have medicinal properties and have been used by local people to treat various ailments. Of these plants, nineteen families, 37 genera and 43 species belonged to medicinal plants. Among them, Lamiaceae with 8 species and Malva L. with 3 species were the largest medicinal plant families and genera, respectively. These plants are often used as decoction (28%) and as powder (21%). Also, the fruit of these plants are used most often. Besides being used as medicinal plants, they have other uses such as food, fuel, etc. Malva sylvestris has the largest value of relative frequency of citation and cultural importance indices. The most ailment categories have the highest level of informant agreement (mean FIC=0.92). CONCLUSION: Despite the semi-desert climate and lack of rich vegetation, many medicinal and economic plants are found in Sirjan region. Uncontrolled harvesting of the medicinal plants such as Bunium persicum, Cuminum cyminum, Zataria multiflora and Satureja bachtiarica in this region by local people has increased the risk of their extinction and calls for a restrict control over their protection by the authorities.

Effects of LI4 acupressure on labor pain in the first stage of labor.

INTRODUCTION: Complementary and alternative medicines have been used to decrease labor pain for many years. Despite reports that some of these methods reduce pain, increase maternal satisfaction, and improve other obstetric outcomes, they have received limited attention in the US medical literature. The purpose of this study was to evaluate the effects of LI4 acupressure on labor pain in the first stage of labor, on labor duration, and on patient satisfaction. METHODS: A single, blind, randomized clinical trial was performed with eligible women (N = 100) who were at the beginning of the active phase of labor (3-4 cm dilatation of cervix with regular uterine contractions). The women in the acupressure group (n = 50) received LI4 acupressure at the onset of the active phase for the duration of each uterine contraction over a period of 20 minutes, and the women in the control group (n = 50) received a touch on this point without massage. Labor pain was measured using a structured questionnaire of a subjective labor pain scale (visual analogue scale) before the intervention, immediately after the intervention, 20 and 60 minutes after the intervention, and then every hour. RESULTS: There were significant differences between the groups in subjective labor pain scores immediately and 20, 60, and 120 minutes after intervention (P ≤ .001). Active phase duration (3-4 cm dilatation to full dilatation) and second stage duration (full dilatation to birth) were shorter in the acupressure group. The women in the acupressure group reported greater satisfaction. DISCUSSION: LI4 acupressure was effective at decreasing pain and duration of labor. The participants were satisfied, and no adverse effects were noted.

The assessment of osteoporosis risk factors in Iranian women compared with Indian women.

BACKGROUND: Osteoporosis is an important public health problem in older adults. It is more common in postmenopausal women and not only gives rise to morbidity but also markedly diminishes the quality of life in this population. There is lack of information about the risk factor of osteoporosis in developing countries. In this study we aimed to assess the risk factors for osteoporosis in postmenopausal women from selected BMD centers of two developing Asian countries (Iran and India). METHODS: This study is a multicenter interview-based study conducted in selected hospitals and health centers from urban areas in Iran and India. The case group included postmenopausal osteoporotic women who were identified as patients with bone density higher than 2.5 SD below average of young normal bone density (in L1-L4) spine region interest and/or total femoral region) by using DEXA method. The controls were chosen from postmenopausal women with normal bone density (in L1-L4 spine and total femoral regions using DEXA method) matching in age groups was strategy of choice.The sample sizes included from Iran a total of 363 subjects (178 osteoporotic and 185 normal) and from India a total of 354 subjects (203 osteoporotic and 151 normal). RESULTS: The significant (p < 0.05) risk factors in present study population with their Odds Ratios (in parenthesis, respectively in Iran and India) were as follow:Lower education defined as less than class 12 or nil college (2.1) (2.7), duration of menopause greater than 5 years: (2.2) (1.4), Menarche age (after 14 years): (1.9) (1.6), Menopause age (before 45 years): (1.1) (2), Parity more than 3: (1.1) (1), Bone and joint problem (2.3) (2.2). Calcium supplementation (0.6) and HRT (0.4) were shown as protective factors and steroid therapy (3.3) was found as a risk factor in Iran. Calcium supplementation more than 1 year (0.3) was shown as a protective factor in India.Pure vegetarianism: (2.2) and Red meat consumption more than 4 times per week (1.4) was shown as a risk factor in Indian and Iranian subjects respectively. Regular consumption of Soya (0.3), almond (0.5), fish (0.5), fruits (0.4) and milk tea 4 cups per day and more (0.4) appeared to be significant protective factors in India. Regular consumption of cheese (0.5), milk (0.5), chicken (0.4), egg (0.6), fruit (0.4), tea 7 cups per day and more (0.3) were found to be significant protective factors in Iran. Exercises were shown as protective factor in Iran (0.4) and India (0.4). There were no significant differences in association of risk factors and osteoporosis between Iranian and Indian subjects. CONCLUSION: Osteoporosis in Iranian and Indian subjects also appears to be associated with several known risk factors that well described in the literature. There were no significant differences in association of risk factors and osteoporosis between Iranian and Indian subjects. It was shown a protective role of certain nutritional dietary components and also exercises in both populations and can be exploited in preventive educational strategies on osteoporosis in these populations.
