SUMMARY Objective: The aim of this retrospective case-control study was to evaluate the influence of different occlusal characteristics and self-referred bruxism in the presence of noncarious cervical lesions (NCCLs). Methods and Materials: The participants were 280 students (140 cases and 140 controls), with an average age of 24.5 years, from six schools of dentistry in Spain. Clinical examination was carried out to record the NCCLs and the static and dynamic occlusal characteristics. The side of mastication and bruxism was collected by questionnaire. Data variables were analyzed by means of univariate and multivariate logistic regression. Odds ratios and the respective 95% confidence intervals were calculated (p<0.05). Results: The presence of NCCLs was significantly more likely in subjects with protrusive interferences (odds ratio [OR]=1.82); with lateral interferences, especially on the nonworking side (OR= 1.77); or who were self-reported bruxists (OR=1.72). In the multivariate analysis, protrusive interferences, bruxism, age, and the presence of attrition were risk factors for the development of NCCLs. These factors resulted in a model with an area under the receiver-operating characteristic curve of 0.667 and a positive predictive value of 61.43%. Conclusions: There was no significant relationship between most occlusal factors and the presence of NCCLs. Only bruxism, protrusive interferences, age, and occlusal wear were risk factors. The predictive model was not sufficiently explanatory. Occlusal factors alone do not appear to be sufficient to explain the presence of NCCLs.

Asfiksia perinatal merujuk pada kekurangan oksigen selama persalinan, sehingga berpotensi menyebabkan kematian dan kecacatan. WHO memperkirakan  4 juta anak terlahir dengan asfiksia setiap tahun, dimana 1 juta di antaranya meninggal dan 1 juta anak bertahan hidup dengan gejala sisa neurologis yang parah. Penelitian ini bertujuan untuk menganalisis faktor risiko fetal dan tali pusat pada asfiksia neonatal.Penelitian dilakukan di lakukan di RS Dr Moewardi Surakarta dengan pendekatan  quantitative retrospective case control study. Data diambil dari rekam medis antara  tahun 2013-2018. Penelitan ini melibatkan  264 neonatal yang terdiri dari 88 kelompok kasus dan 176  kelompok control. Kelompok kasus adalah bayi dengan diagnosa  asfiksia yang  dilakukan analisis terhadap faktor risiko fetal, sedangkan bayi yang tidak mengalami asfiksia dijadikan  kelompok kontrol. Hasil analisis statistik uji Chi-Square dan Fisher Exact ditemukan bahwa  kelahiran prematur (OR 2,07 CI 95% P 0,02), persalinan dengan tindakan (OR 3,61 CI 95% P 0,00), berat bayi (OR 2,85 CI 95% P 0,00), posisi janin (OR 2,37 CI 95% P 0,05), tali pusat ( QR 3,071 CI 95%  P 0,01)  berisiko terhadap insiden asfiksia perinatal. Air ketuban yang bercampur meconium (OR 1,51 CI 95% P 0,16) tidak memiliki risiko  dengan Asfiksia perinatal. Kesimpulan: Risiko terhadap insiden asfiksia perinatal  meliputi kelahiran prematur, persalinan dengan tindakan, berat bayi, posisi janin,  dan tali pusat.Perinatal asphyxia refers to a lack of oxygen during labor, which has the potential to cause death and disability. WHO estimates  4 million children born with asphyxia each year, in  which 1 million dies and 1 million survive with severe neurological sequelae. This study aims to analyze fetal and umbilical risk factors in neonatal asphyxia.This research is a quantitative retrospective case-control study, which was conducted at The Dr. Moewardi  hospital,  Surakarta. Data was taken from  medical records from 2013-2018. The case group was patients diagnosed  asphyxia, while those who did not experience asphyxia were treated as a control group.  A total of 264  samples, consisting of 88 case group respondents and 176 control group respondents. Statistical analysis Chi- Square and Fisher Exact found that preterm birth (OR 2.07 CI 95% P 0.02), labor with instrument or complication (OR 3.61 CI 95% P 0.00), infant weight (OR 2.85 CI 95% P 0, 00), fetal position (OR 2.37 CI 95% P 0.05), umbilical cord (QR 3.071 CI 95% P 0.01) are at risk for the incidence of perinatal Asphyxia. The amniotic fluid mixed with meconium (OR 1.51 CI 95% P 0.16) has no risk with perinatal asphyxia.The risk factors of incidences of perinatal asphyxia were  preterm birth, labor with instrument or complication, baby weight, fetal position and umbilical cord.

ObjectivesThe aim of this study was to identify prehospital and early hospital risk factors associated with 30-day mortality in patients with blood culture-confirmed community-acquired bloodstream infection (CA-BSI) in Sweden.MethodsA retrospective case–control study of 1624 patients with CA-BSI (2015–2016), 195 non-survivors satisfying the inclusion criteria were matched 1:1 with 195 survivors for age, gender and microorganism. All forms of contact with a healthcare provider for symptoms of infection within 7 days prior CA-BSI episode were registered. Logistic regression was used to analyse risk factors for 30-day all-cause mortality.ResultsOf the 390 patients, 61% (115 non-survivors and 121 survivors) sought prehospital contact. The median time from first prehospital contact till hospital admission was 13 hours (6–52) for non-survivors and 7 hours (3–24) for survivors (p<0.01). Several risk factors for 30-day all-cause mortality were identified: prehospital delay OR=1.26 (95% CI: 1.07 to 1.47), p<0.01; severity of illness (Sequential Organ Failure Assessment score) OR=1.60 (95% CI: 1.40 to 1.83), p<0.01; comorbidity score (updated Charlson Index) OR=1.13 (95% CI: 1.05 to 1.22), p<0.01 and inadequate empirical antimicrobial therapy OR=3.92 (95% CI: 1.64 to 9.33), p<0.01. In a multivariable model, prehospital delay >24 hours from first contact remained an important risk factor for 30-day all-cause mortality due to CA-BSI OR=6.17 (95% CI: 2.19 to 17.38), p<0.01.ConclusionPrehospital delay and inappropriate empirical antibiotic therapy were found to be important risk factors for 30-day all-cause mortality associated with CA-BSI. Increased awareness and earlier detection of BSI in prehospital and early hospital care is critical for rapid initiation of adequate management and antibiotic treatment.
