Context: Squats and lunges are common exercises frequently applied in muscle-strengthening and therapeutic exercises. The loading devices are often used to increase the training intensity. Objective: To determine the effect of loading devices on muscle activation in squat and lunge and to compare the differences in muscle activation between squat and lunge. Design: Cross-sectional cohort. Participants: Nineteen healthy, male, recreationally active individuals without a history of lower limb injury. Interventions: Each participant performed 10 repetitions of a squat under 5 conditions: unloaded, barbell, dumbbell, loaded vest, and kettlebell, and 10 repetitions of a lunge under 4 conditions: unloaded, barbell, dumbbell, and loaded vest. Main Outcome Measures: The electromyography signals of quadriceps, hamstrings, tibialis anterior, gastrocnemius lateralis and medialis were measured. One-way repeated-measure analysis of variance was used to compare the difference among different loading conditions. Paired t test was used to compare the difference between squat and lunge. Results: The muscle activation in the loaded conditions was significantly higher than that in nonloaded conditions in squat and lunge. Compared with the barbell, dumbbell, and loaded vest conditions, the semitendinosus showed significantly higher activation, and the tibialis anterior showed significantly lower activation in kettlebell condition in squat. No significant difference in muscle activation was found among barbell, dumbbell, and kettlebell conditions in lunge. In addition, quadriceps and hamstring activities were significantly higher in lunge than in squat. Conclusions: Muscle activation was affected by the loading devices in squat but not affected in lunge. Kettlebell squat could be suggested for targeting in strengthening medial hamstring. Progressive strengthening exercise could be recommended from squat to lunge based on sequential activation level.

Introduction: Postpartum period is often considered as temporary or unimportant thing. Thus, the postpartum treatment becomes the ignored aspect from the women's health. The social support is important for mother's and child's prosperity. This research is aimed to examine the difference and the influence of social support score and the quality of life postpartum mothers by home visit 1, 2, and 3. Method: This research employs cross sectional design with longitudinal repeated measure design. The sample of this research was postpartum mothers that give birth in the village of Sukodono subdistrict area from 3 to 40 days. The sample is selected by purposive sampling. Results: There is no significant difference of mean between husband's, parents', parents-in-law's, and relative's support (p > 0.05). There is no significant difference between the quality of life postpartum mother (p > 0.05). The regression equality of social support to quality of life pospartum mother in K1, K2, and K3 were 0,157 + 0.702*husband's support, 0.099 + 0.370*husband's support – 0.674*relative's support, and 0,123+0,0674*husband's support-0,633*relative's support, respectively. Discussion. Husband's support increase quality of life pospartum mother. This is suggested to plan education in-service about the important of social support after giving birth for midwife or nurse that has role to service the mothers. Giving the education of postpartum preparation is not only for the mothers, but also for their husband. Keywords: relative's support, quality of life, postpartum

Abstract: Routine blood examination is the earliest blood test or screening test to determine the diagnosis of an abnormality. Blood easily froze if it is outside the body and can be prevented by the addition of anticoagulants, one of which Ethylene Diamine Tetra Acetate (EDTA). Currently available vacuum tubes containing EDTA anticoagulants in the form of K2EDTA and K3EDTA. K3EDTA is usually a salt that has better stability than other EDTA salts because it shows a pH approaching a blood pH of about 6.4. The purpose of this research is to know the difference of erythrocyte index results include MCH, MCV and MCHC using K3EDTA anticoagulant with K2EDTA. This research is a cross sectional design. This study used venous blood samples mixed with K2EDTA anticoagulant and venous blood mixed with K3EDTA anticoagulants, each of 30 samples. Data were collected and analyzed using paired different test. Based on data analysis that has been done on MCH examination, p value <0,05 then there is a significant difference between samples with K3EDTA anticoagulant with K2EDTA to erythrocyte index value. Then on the examination of MCV and MCHC obtained p value <0.05 then there is no significant difference between samples with K3EDTA anticoagulant with K2EDTA to erythrocyte index value.Abstrak: Pemeriksaan darah rutin merupakan pemeriksaan darah yang paling awal atau screening test untuk mengetahui diagnosis suatu kelainan. Darah mudah membeku jika berada diluar tubuh dan bisa dicegah dengan penambahan antikoagulan, salah satunya Ethylene Diamine Tetra Acetate (EDTA). Dewasa ini telah tersedia tabung vakum yang sudah berisi antikoagulan EDTA dalam bentuk  K2EDTA dan  K3EDTA. K3EDTA  biasanya berupa garam yang mempunyai stabilitas yang lebih baik dari garam EDTA yang lain karena menunjukkan pH yang mendekati pH darah yaitu sekitar 6,4. Tujuan dari penelitian ini adalah untuk mengetahui perbedaan hasil indeks eritrosit meliputi MCH, MCV dan MCHC menggunakan antikoagulan K3EDTA dengan K2EDTA. Penelitian ini merupakan penelitian dengan desain cross sectional. Penelitian ini menggunakan sampel darah vena yang dicampur dengan antikoagulan K2EDTA dan darah vena yang dicampur dengan antikoagulan K3EDTA, masing-masing sebanyak 30 sampel. Data dikumpulkan dan dianalisis menggunakan uji beda berpasangan.

Introduction: The primary attachment figure is mostly defined as the mother, and studies focus on the mother. However, in many babies, basic attachment is just as good with the father as with the mother. It is seen that there are very few studies in the literature investigating the correlations of father-infant attachment relationships.. The aim of this study is to determine the father-infant attachment status and to determine the factors affecting attachment. Method: The population of the cross-sectional study consisted of the spouses of all puerperant women hospitalized in the Gynecology and Obstetrics Clinic between September 1, 2018 and October 1, 2018. The sample size consisted of 156 fathers who agreed to participate in the study. Father identification form and father-infant attachment scale were used to collect the study data. The analysis of the data obtained from the research was carried out on the computer using the SPSS 16.0 package program. Results: 156 fathers participated in the study. The mean age of the fathers is 33.64±6.49, and 38.5% of them have a bachelor's degree. 91.0% of fathers stated that they felt ready for fatherhood. The fathers' Father-Infant Attachment Scale mean score was 82.60±7.72 In the analysis, the difference between the variables and the total score of the scale was found to be statistically insignificant (p>0.05). Discussion and Conclusion: At the end of the study, the bonding process of fathers participating in the study with their babies and the factors affecting this process were evaluated and it was seen that the father-infant attachment scale mean scores of the fathers participating in the study were high and were similar to other studies. In addition, when the basic factors affecting father-infant attachment were compared with the attachment scale mean score, it was found that there was no statistically significant difference.

Background: Radiological grading of wrist osteoarthritis associated with scaphoid nonunion advanced collapse (SNAC) can be difficult. A comparison radiograph of the contralateral healthy wrist and an educational training in the various SNAC stages may improve reliability. Our purposes were to evaluate the difference in the reliability: (1) between observers who rate SNAC wrists with and without a comparison radiograph; and (2) between observers who receive training prior to ratings and those who do not. Methods: In this cross-sectional survey study, 82 fully trained orthopedic or hand surgeons rated anteroposterior radiographs of 19 patient wrists following a scaphoid nonunion based on SNAC stages 0 to 4. Observers were randomized online in 4 groups: one group rated unilateral views without training, a second group unilateral views with training, a third group bilateral views without training, and a fourth group bilateral views with training. Training included a 1-page clarification of the SNAC stages. Interobserver agreement was calculated using kappa statistics. Results: There was no significant difference between agreement between observers who rated unilateral radiographs (κ = 0.55) and who rated bilateral radiographs (κ = 0.58) ( P = .14), nor between agreement between observers who received training (κ = 0.59) and who did not (κ = 0.54) ( P = .058). Conclusions: The use of an additional comparison view and/or training does not seem to be clinically relevant in SNAC staging. There is room for improvement in the way we assess patients with SNAC wrists.

Abstract: Haemoglobin is the main component of red blood cells that serves as a transporter of oxygen and carbon dioxide in the blood. The normal range of haemoglobin values can be used to determine the degree of anemia according to age and gender. Geographical condition such as altitude influences the haemoglobin value. This study aimed to obtain the difference of haemoglobin levels between teenagers with good nutrition status who live at the highland and those at the seaside. This was an observational analytical study with a cross sectional design. Samples were students with good nutrition status of SMPN 3 Tomohon (living at the highland) and those of SMP Kristen Nazaret Tuminting (living at the seaside). There were 60 students who met the inclusion criteria as follows: adolescent, good nutrition status, healthy, aged 13-15 years, lived at the highland or at the seaside ≥ 6 month, and willing to be performed blood examinations, and had been approved by their parents. The Mann-Whitney test for the difference between haemoglobin levels of the two groups showed a p value < 0,001. Conclusion: There was a very significant difference between haemoglobin levels of good nutrition teenagers who lived at the highland and at the seaside. Keywords: haemoglobin levels, good nutrition, teenagers, highland, seaside  Abstrak: Hemoglobin merupakan komponen utama sel darah merah dan berfungsi sebagai transporter oksigen dan karbon dioksida dalam darah.

Background: Several studies have demonstrated an association between obesity and migraine. It’s still unclear whether migraine is the cause or it's the result of obesity. Objective: We investigated the prevalence of migraine among obese and non-obese individuals and analyzed the relationship between migraine prevalence and obesity. Patients and Methods: This is cross-sectional observational study was carried out at the neurology outpatients’ department of the Rizgary Teaching Hospital in Erbil, Iraq, from July 1st , 2018 to September 30, 2019. We interviewed and examined 300 persons, both obese (n=154) and non-obese (n=146), and of both gender. All of them were adults (>18 years old). Each person's weight, height, body mass index (BMI), and waist circumference were measured.The diagnosis of migraine was made according to the International Headache Society’s criteria. Obesity was present if the individual’s BMI is ≥30 and/or waist-to-hip ratio is >0.9 in females and >1.0 in males. Results: Out of the 300 persons, 14 males (8.5%) got migraines while migraine was found in 37 females (27.4%), irrespective of their weight. Out of the 300 persons, the prevalence of migraine among obese individuals was 21.4% (n=33) and while in non-obese individuals was 12.3% (n=18). There was a statistically significant difference between the groups (p-value=0.045). The overall prevalence of migraine was 16.9% of the persons interviewed. Conclusion: The results showed that migraine is more prevalent among obese persons than non-obese persons and the difference was statistically significant.

Abstract Background The shoulder joint is the most commonly injured joint in CrossFit practitioners, because of the high intensity and loads associated with this sport. Despite the large number of clinical cases, there is a shortage of studies that investigate influence of biomechanical aspects of upper limbs' injuries on CrossFit practitioners. This study hypothesized that there would be a difference in function, strength, and muscle activation between Crossfit practitioners with and without shoulder pain. Methods We divided 79 Crossfit practitioners into two groups according to whether they reported pain (n = 29) or no pain (n = 50) in the shoulder during Crossfit training. Muscle function, strength, and activation were assessed using the Disability Arm, Shoulder and Hand function questionnaire, Upper Quarter Y Balance Test and Closed Kinetic Chain Upper Extremity Stability Test shoulder tests, isometric muscle strength assessment by manual dynamometry and muscle activation by surface electromyography and pain report. Results The function based on questionnaire was associated with pain (p = 0.004). We observed a statistically significant difference between the two groups only in the surface electromyography activity of the lower trapezius, and in the variables of shoulder pain and function (p = 0.038). Conclusion Crossfit practitioners with shoulder pain occurring during training showed good function and stability of the shoulder joint, but there was a reduction in the activation of stabilizing muscles, especially the lower trapezius.

The height of the maxillary alveolar ridge can be measured using panoramic radiography. The decline occurred because the height of the alveolar ridge undergoes slow physiological resorption due to the absence of mechanical stimulus. The purpose of this research is to know the difference and the average height of the maxillary alveolar ridge in edentulous and dentate women using panoramic radiography. This study is an analytical method with a cross-sectional approach. A total sample of 40 women, edentulous and dentate has been measured. Measurements were made by measuring the distance between the lowest point of the infraorbital ridge and alveolar crest maxilla on the incisor point, right and left premolar, right and left molar. A statistical test is done using independent t-test. The results showed that the average value of a dentate women sample is greater than edentulous. The average value obtained by the dentate sample is greatest in incisor point by 37,57mm± 3,34mm and the smallest at the right molar point by 33,87mm ± 2,81mm. The average value obtained by the edentulous sample is greatest in incisor point by 35,30mm ± 2,79mm and the smallest at the right molar point by 31,84mm ± 3,85mm. It can be concluded that there is a significant difference in the height of the maxillary alveolar ridge on an edentulous sample and dentate, except the right molar teeth. The average height of the maxillary alveolar ridge in an edentulous sample is 33,35mm ± 3,43mm, and the dentate sample is 35,66mm ± 3,21mm.
