Context:  Few researchers have identified intrinsic risk factors for shoulder injury in team handball players by analyzing measurements of maximal isokinetic rotator muscle strength. Objective:  To identify possible intrinsic risk factors for shoulder injury by analyzing measurements of maximal isokinetic rotator muscle strength. Design:  Cross-sectional study. Setting:  Male team handball senior divisions (the highest level) in France and Belgium. Patients or Other Participants:  A total of 108 male high-level handball players (age = 24 ± 4 years, height = 189 ± 6 cm, mass = 87 ± 11 kg) were enrolled. Main Outcome Measure(s):  All players completed a preseason questionnaire and performed a bilateral isokinetic assessment of the shoulder rotator muscles. On a monthly questionnaire, players reported any shoulder injury that they sustained during the season. Results:  On the preseason questionnaire, 51 of 108 (47%) participants reported a history of dominant-shoulder injury. A total of 106 participants completed the in-season questionnaire, with 22% (n = 23) reporting a shoulder injury on their dominant side during the subsequent season. Fourteen percent (n = 15) sustained microtraumatic injuries, and 8% (n = 8) described a traumatic injury. Backcourt players had a 3.5-times increased risk of injury during the new season compared with players in other positions. Among the isokinetic results, no risk factor for further injury was identified in handball players with microtraumatic injuries. For traumatic injuries, the concentric maximal strength developed by the internal rotators at high speed (240°/s) in the dominant shoulder was a protective factor against the risk of further injury. Conclusions:  These results can potentially identify intrinsic risk factors for shoulder injury and may be used to determine potential interventions for reducing this risk in handball players.

Background: Many studies have investigated isokinetic performance in volleyball players but not through surface maps.Objectives: The goals of this study were to assess velocity-specific isokinetic knee extensor–flexor muscle strength and to compare the isokinetic knee extensor–flexor muscles between professional (PRO) and under-17 (U17) female volleyball players.Method: This cross-sectional laboratory study was developed with two groups: PRO (n = 12), medianage = 21.3 years, and U17 (n = 9), medianage = 15 years. Peak torque, total work, mean power, angle of peak torque, hamstring–quadriceps torque ratio (H–Q ratio) and torque–angle–velocity surface maps were analysed from knee extension–flexion at 60, 120 and 300 degrees per second (°/s).Results: Significant differences were identified for extensor peak torque between PRO x = 202.3 Newton metre (N·m) (standard deviation [SD] = 24.4) and U17 x = 141.6 N·m (30.1) at 60 °/s (p < 0.001; d = 2.21) as well as flexor peak torque (PRO x = 75.7 N·m [10.3] and U17 x = 57.7 N·m [11.4]) at 120 °/s (p < 0.001; d = 1.65) for the dominant limb. There were also significant group differences for total work and mean power at all velocities for extension and flexion. Surface maps demonstrated higher torque at lower speeds for both groups with smaller torque changes across velocities for flexion.Conclusion: Different groups of female volleyball players showed contrasting concentric knee muscle strength across isokinetic velocities.Clinical implications: These results demonstrate the importance of specific strength training for different age groups, even within the same sport, and provide insight into muscle strength.

Abstrak Pil KB oral merupakan salah satu alat kontrasepsi paling banyak digunakan oleh para wanita untuk mencegah kehamilan. Namun pil KB juga memiliki efek samping yang dapat meningkatkan tekanan darah ?140 mmHg (sistolik) dan ?90 mmHg (diastolik) atau dikenal dengan hipertensi. Penelitian ini bertujuan untuk mengetahui apakah penggunaan kontrasepsi pil KB oral dapat menimbulkan resiko terjadinya hipertensi. Metode yang digunakan dalam penelitian ini adalah literture review dengan sumber data melalui pencarian secara menyeluruh dengan mesin pencari PubMed dan Google Scholar untuk menemukan artikel sesuai kriteria inklusi dan ekslusi dengan kata kunci tertentu dalam periode 2010-2020 kemudian dilakukan review. Hasil penelusuran yang didapatkan yaitu 3 artikel ilmiah secara observasional dengan menggunakan metode cohort dan cross sectional. Hasil dari literature review ini menunjukkan bahwa penggunaan kontrasepsi pil KB oral dapat menimbulkan risiko terjadinya hipertensi. Hal tersebut dibuktikan dari artikel ilmiah yang memiliki nilai p-value dibawah 0,05. Namun adapula yang membuktikan bahwa penggunaan kontrasepsi oral di usia muda tidak menyebabkan hipertensi pascamenopause serta terdapat artikel yang menyatakan bahwa tidak ada hubungan yang signifikan antara penggunaan pil KB kombinasi yang didapatkan dari klinik AS dengan penggunaan pil KB kombinasi yang didapatkan tanpa resep dokter tapi penggunaan pil KB perlu lebih di pantau agar tidak terjadi resiko yang diinginkan. Kata Kunci : Hipertensi, literature review, pil KB Abstract Oral contraceptive pills are one of the most widely used contraceptives for women to prevent pregnancy. However, oral contraceptive pills also have side effects, one of which is increasing blood pressure to ? 140 mmHg (systolic) and ? 90 mmHg (diastolic) or known as hypertension. This study aimed to determine whether the use of oral contraceptive pills poses a risk of developing hypertension. The method used in this study was literature review whose data were sourced from thorough searches with the PubMed and Google Scholar to find articles according to the inclusion and exclusion criteria with certain keywords in the 20102020 and then reviewed. The results obtained were 7 scientific articles observed using a case control and cross sectional methods. The results of this literature review indicate that the use of oral contraceptive pills can increase the risk of developing hypertension. This is evidenced by scientific articles with a p-value below 0.05. However, there is also evidence that the use of oral contraceptives at a young age does not cause postmenopausal hypertension and there is an article stating that there is no significant link between the use of combination birth control pills obtained from U.S. clinics and the use of combination birth control pills obtained without a doctor's prescription but the use of birth control pills needs to be monitored more so that there is no desired risk.

The association between fatigue and sarcopenia is not well understood, therefore, this study aimed to compare the sarcopenia measures among elderly with mild and severe fatigue and to determine whether fatigue severity is associated with sarcopenia measures. This was a cross-sectional study conducted on201 elderly (age = 68.45±6.30 years). The elderly was classified into either mild or severe fatigue based on the Fatigue Severity Scale (FSS), meanwhile, sarcopenia measures include SARC-F score, muscle mass (ASM/height2), calf circumference (CC), upper (handgrip) and lower limb muscle strength, as well as physical performance (gait speed). Data were analyzed using independent t-tests and logistic regression. The results showed that elderly with severe fatigue were significantly older, with lower muscle strength, and slower gait speed (all p-value <0.05). After adjusting for age, fatigue severity remained significantly associated with SARC-F score (OR = 1.583, 95% CI = 1.262-1.986, p-value = 0.001) and CC (OR = 1.103, 95% CI = 1.014-1.200, p-value = 0.022). Moreover,when the SARC-F score was removed from the regression model, fatigue severity was significantly associated with CC (OR = 1.088, 95% CI = 1.006-1.178, p-value = 0.036) and gait speed (OR = 0.011, 95% CI = 0.001-0.168, p-value = 0.001). Based on the results, fatigue severity is associated with SARC-F score, CC, and gait speed, therefore, interventions targeted at sarcopenia measures is recommended to optimize physical endurance in the elderly.

Kelainan otot rangka merupakan gangguan fungsi otot, tendon, saraf, pembuluh darah, tulang dan ligamen yang biasa diderita oleh pekerja dengan aktivitas kerja menggunakan kekuatan otot, seperti pekerja laundry. Penelitian ini bertujuan mengetahui sikap kerja pekerja laundry dan hubungan dengan risiko musculoskeletal disorders di Kecamatan Purwokerto Utara. Penelitian ini menggunakan desain studi potong lintang dengan teknik pengambilan sampel menggunakan quota sampling dengan kriteria inklusi responden bekerja hanya pada satu bagian kerja tertentu dari laundry, tidak memiliki keterbatasan komunikasi dan kriteria eksklusi responden keluar dari pekerjaan dan tidak bersedia dijadikan responden. Sampel sebanyak 150 orang dengan kuota masing-masing bagian diambil sebagai sampel sebanyak 30 orang, meliputi bagian penimbangan, pencucian, pengeringan, penyetrikaan dan pengemasan. Penelitian menemukan sikap kerja yang berhubungan dengan risiko kelainan otot rangka adalah pada bagian pencucian (nilai p = 0,014, nilai p < 0,05). Sedangkan sikap kerja bagian penimbangan (nilai p = 0,77), pengeringan (nilai p = 0,257), penyetrikaan (nilai p = 0,109) dan pengemasan (nilai p =0,370) tidak berhubungan dengan risiko MSDs (nilai p > 0,05). Hanya sikap kerja pada bagian pencucian yang berisiko menimbulkan MSDs, sehingga perlu dilakukan intervensi berupa pelatihan sikap kerja mencuci yang benar.Musculoskeletal disorders (MSDs) are disorders of muscle function, tendons, nerves, blood vessels, bones and ligaments that usually occur in workers with work activities using muscle power, such as laundry workers. The study aimed to determine the attitude of the working relationship with the risk of MSDs in the Nothren Purwokerto district. Type cross-sectional study with a quantitative approach. The sampling technique using quota sampling with inclusion criteria of the respondents worked only on one particular part of the laundry work, they do not have any communication limilimitations and exclusion criteria respondents out of work and not willing to be the respondent. Based on these criteria obtained a sample of 150 people with a quota of each section is taken as a sample of 30 people, which is part of the weighing, washing, drying, ironing and packing. The results showed that the attitude of work-related MSDs are at the risk of leaching (p value= 0.014, p< 0.05). While the attitude of the weighing part employment (p= 0.77), drying (p= 0.257), ironing (p= 0.109), and packaging (p= 0.370) was not associated with risk of MSDs, because the value of p> 0.05. So it is concluded that only work attitude on the part pose a risk of MSDs washing. Therefore, it is necessary to intervene in the form of job training wash right attitude.

Background: The Novel Coronavirus (Covid-19) disease caused by SARS-COV2 was first discovered in Wuhan, China, December 2019. WHO has set Covid 19 to be a pandemic which has resulted in an increase in death rates worldwide. Covid-19 attacks the respiratory system which resembles pneumonia but has signs of a decrease in oxygen saturation. In Indonesia, many people, especially men, practice smoking, where smoking can cause respiratory system problems, but there is no sign of a decrease in oxygen saturation. Objectives: This study aims to determine the effect of smoking on oxygen saturation levels in Covid-19 patients. Methods: This type of research is an analytic study with a cross sectional design. Total population of 52 people, with inclusion and exclusion criteria. Results: This study shows that 21.2% of patients who smoke 6-12 cigarettes / day have oxygen saturation <75%, with the result p-value = 0.000, which means that there is an effect between smoking on decreasing oxygen saturation, with a 53-fold chance of covid patients. People who smoke can cause a decrease in oxygen saturation. Conclusion: Decrease in oxygen saturation in covid-19 patients, can be caused due to the toxicity of cigarettes smoked. In smokers who are confirmed Covid-19, there will be an worsening of oxygen supply in the blood, which is indicated by a decrease in oxygen saturation <75%.
