Relying on a sample of 1,381 US-based multiple homicide offenders (MHOs), we study the duration of the careers of this extremely violent category of offenders through Kaplan–Meier estimation and Cox Proportional Hazard regression. We investigate the characteristics of such careers in terms of length and we provide an inferential analysis investigating correlates of career duration. The models indicate that MHOs employing multiple methods, younger MHOs and MHOs that acted in more than one US state have higher odds of longer careers. When controlling for career-based attributes, female MHOs are also correlated with longer careers.

Relying on a sample of 1,394 US-based multiple homicide offenders (MHOs), we study the duration of the careers of this extremely violent category of offenders through Kaplan-Meier estimation and Cox Proportional Hazard regression. We investigate the characteristics of such careers in terms of length and we provide an inferential analysis investigating correlates of career duration. The models indicate that females, MHOs employing multiple methods, younger MHOs and MHOs that acted in more than one US state have higher odds of longer careers. Conversely, those offending with a partner and those targeting victims from a single sexual group have a higher probability of shorter careers.

BackgroundBleb needling is widely used to restore flow and lower intraocular pressure (IOP) in a failing trabeculectomy. We aimed to measure the safety and efficacy of needling in a large cohort and identify factors that were associated with success and failure.MethodsThis retrospective audit included all patients who underwent needling at Addenbrooke’s Hospital, Cambridge over a 10-year period. Data were available on 91 patients (98% of patients identified), including 191 needlings on 96 eyes. Success was defined as IOP below 21 mm Hg or 16 mm Hg or 13 mm Hg consistently, without reoperation or glaucoma medication. Risk factors for failure were assessed by Cox proportional hazard regression and Kaplan-Meier curves.ResultsSuccess defined as IOP <16 mm Hg was 66.6% at 12 months and 53% at 3 years and success defined as IOP <21 mm Hg was 77.1% at 12 months and 73.1% at 3 years. Failure after needling was most common in the first 6 months. Factors that predicted failure were flat or fibrotic blebs (non-functional) and no longer injected, while success was predicted by achieving a low IOP immediately after needling. No significant complications were identified.ConclusionNeedling was most successful soon after trabeculectomy, but resuscitation of a long-failed trabeculectomy had lower likelihood of success. The safety and efficacy compare favourably with alternative treatment approaches.

Abstract Background An unexpected excess in weight gain has recently been reported in the course of dolutegravir (DTG) treatment. The aim of the present study was to investigate whether weight gain differs among different DTG-containing regimens. Methods Adult naïve and experienced people with HIV (PWH) initiating DTG-based antiretroviral therapy (ART) between July 2014 and December 2019 in the Surveillance Cohort Long-Term Toxicity Antiretrovirals (SCOLTA) prospective cohort were included. We used an adjusted general linear model to compare weight change among backbone groups and a Cox proportional hazard regression model to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for weight increases &gt;10% from baseline. Results A total of 713 participants, 25.3% women and 91% Caucasian, were included. Of these, 195 (27.4%) started DTG as their first ART regimen, whereas 518 (72.6%) were ART-experienced. DTG was associated with abacavir/lamivudine in 326 participants, tenofovir disoproxil fumarate/emtricitabine (TDF/FTC) in 148, boosted protease inhibitors in 60, rilpivirine in 45, lamivudine in 75, and tenofovir alafenamide (TAF)/FTC in 59. At 6 and 12 months, weight gain was highest among PWH on TDF/FTC+DTG and TAF/FTC+DTG. Baseline CD4 &lt;200 cells/mm3 (HR, 1.84; 95% CI, 1.15 to 2.96), being ART-naïve (HR, 2.24; 95% CI, 1.24 to 4.18), and treatment with TDF/FTC+DTG (HR, 1.92; 95% CI, 1.23 to 2.98) or TAF/FTC+DTG (HR, 3.80; 95% CI, 1.75 to 8.23) were associated with weight gain &gt;10% from baseline. Higher weight (HR, 0.97 by 1 kg; 95% CI, 0.96 to 0.99) and female gender (HR, 0.54; 95% CI, 0.33 to 0.88) were protective against weight gain. Conclusions Naïve PWH with lower CD4 counts and those on TAF/FTC or TDF/FTC backbones were at higher risk of weight increase in the course of DTG-based ART.

The Relationship

Background The CKLF-like MARVEL transmembrane domain containing 6 (CMTM6) is a key regulator of the programed death receptor ligand-1 (PD-L1) protein. However, the usefulness of CMTM6 expression as a prognostic indicator and the relationship between CMTM6 and PD-L1 expression in gastric cancer (GC) remains unclear. Objectives We evaluated the expression and prognostic implications of CMTM6 in GC tissue and its relationship with PD-L1 expression. Patients and methods The protein expressions of CMTM6 and PD-L1 were detected in 122 cases of postoperative GC tissue using immunohistochemical (IHC) assays. Kaplan–Meier survival analysis was used to calculate the survival probability and a log-rank test was used to compare the survival curves. Univariate and multivariate Cox proportional hazard regression analyses were used to evaluate the clinically-related factors associated with survival. Pearson’s correlation was used to determine the correlation analysis and estimate the statistical significance. The univariate and multivariate logistic regression analyses were used to analyze the relationship between clinically-related factors and PD-L1 expression. Results Kaplan–Meier survival analysis showed that patients with high CMTM6 expression had shorter overall survival (OS) than those with low expression (P < 0.001). The expression of CMTM6 was an independent risk factor for prognosis in multivariate Cox proportional hazard regression analyses (HR:2.221, CI% [1.36–3.628], P = 0.001). The OS of patients with positively expressed PD-L1 was significantly shorter than those with negatively expressed PD-L1 (P = 0.003). The expression of CMTM6 was significantly related to the positive expression of PD-L1 in gastric cancer tissues (r = 0.186, P = 0.041). The expression of CMTM6 was the independent risk factor for PD-L1 expression in multivariate logistic regression analysis (OR:2.538, CI% [1.128–5.714], P = 0.024). Conclusion CMTM6 expression is significantly related to PD-L1 and may be a useful prognostic indicator and a specific therapeutic target for cancer immunotherapy for GC patients.

Abstract Aim: The purpose of this study was to compare clinicopathological features of patients with non-schistosomal and schistosomal colorectal cancer to explore the effect of schistosomasis on CRC patients` clinical outcomes. Methods: 351 cases of CRC were retrospectively analyzed in this study. Survival curves were constructed by using the Kaplan-Meier method. Univariate and multivariate Cox proportional hazard regression models were performed to identify associations with outcome variables.Results: Patients with schistosomiasis (CRC-S) were significantly older (Table 3, P＜0.001) than patients without schistosomiasis (CRC-NS). However, there were no significant differences between CRC-S and CRC-NS patients in other clinicopathological features. Schistosomiasis were associated with adverse overall survival upon K-M analysis (P=0.0277). By univariate and multivariate analysis, as shown in Table 2, gender (P=0.003), TNM stage (P＜0.001), schistosomiasis (P=0.025), lymphovascular invasion (P=0.030) and cancer node (P＜0.001) were all independent predictors in the whole cohort. When patients were stratified according to clinical stage and lymph node metastasis state. Schistosomiasis was also an independent predictors in patients with stage Ⅲ-Ⅳ tumors and in patients with lymph node metastasis, but not in patients with stage Ⅰ-Ⅱ tumors and in patients without lymph node metastasis.Conclusion: Schistosomiasis was significantly correlated with OS and it was an independent prognostic factor for OS in the whole cohort. When patients were stratified according to clinical stage and lymph node metastasis state, schistosomiasis was still an independent unfavorably prognosis factor for OS in patients with stage Ⅲ-Ⅳ tumors or patients with lymph node metastasis.

Pendahuluan. Dengan meningkatnya jumlah populasi usia lanjut, masalah kesehatan yang dialami juga semakin banyak, salah satunya malnutrisi. Studi di luar negeri menunjukkan malnutrisi pada pasien geriatri yang dirawat di rumah sakit menurunkan kesintasan. Pasien usia lanjut di Indonesia mempunyai karakteristik yang berbeda dengan pasien usia lanjut di luar negeri. Di Indonesia belum ada studi tentang status nutrisi pasien usia lanjut yang dirawat di rumah sakit dan pengaruhnya terhadap kesintasan. Penelitian ini bertujuan mengetahui pengaruh status nutrisi terhadap kesintasan 30 hari pasien usia lanjut yang dirawat di ruang rawat akut geriatri dan ruang rawat penyakit dalam rumah sakit.Metode. Penelitian kohort retrospektif, dengan pendekatan analisis kesintasan, dilakukan terhadap 177 pasien geriatri yang dirawat di ruang rawat akut geriatri dan ruang rawat penyakit dalam Rumah Sakit Cipto Mangunkusumo selama bulan April–September 2011. Data demografis, diagnosis medis, kadar albumin, indeks ADL Barthel, geriatric depression scale, status nutrisi dengan mini nutritional assessment (MNA) dikumpulkan, dan diamati selama 30 hari sejak mulai dirawat untuk melihat ada tidaknya mortalitas. Perbedaan kesintasan kelompok pasien dengan status nutrisi baik, berisiko malnutrisi dan malnutrisi ditampilkan dalam kurva Kaplan-Meier, diuji dengan uji Log-rank, serta analisis multivariat dengan Cox proportional hazard regression model untuk menghitung adjusted Hazard Ratio dan interval kepercayaan 95% terjadinya mortalitas 30 hari dengan memasukkan variabel-variabel perancu sebagai kovariat.Hasil. Kesintasan antara subyek yang status nutrisinya baik, berisiko malnutrisi dan malnutrisi ialah 94,7% dengan 89,0% dan 80,7%, namun perbedaan kesintasan 30 hari tak bermakna dengan uji Log-rank (p=0,106). Pada analisis multivariat didapatkan adjusted HR setelah penambahan variabel perancu sebesar 1,49 (IK 95% 0,29 – 7,77) untuk kelompok berisiko malnutrisi dan 2,65 (IK 95% 0,47 – 14,99) untuk kelompok malnutrisi dibandingkan dengan pasien nutrisi baikSimpulan. Perbedaan kesintasan 30 hari pasien geriatri yang dirawat di rumah sakit yang menderita malnutrisi dan berisiko malnutrisi dibandingkan dengan status nutrisi baik pada awal perawatan belum dapat dibuktikan.

Abstract Background This study was conducted to examine patient characteristics associated with antiretroviral therapy (ART) reinitiation in Medicaid enrollees. Methods This is a retrospective cohort study that uses Cox proportional hazard regression to examine the association between person-level characteristics and time from ART discontinuation to the subsequent reinitiation within 18 months. Results There were 45 409 patients who discontinued ART, and 44% failed to reinitiate. More outpatient visits (3+ vs 0 outpatient visits: adjusted hazard ratio (adjHR), 1.56; 99% confidence interval [CI], 1.45–1.67) and hospitalization (adjHR, 1.18; 99% CI,1.16–1.20) during follow-up were associated with reinitiation. Conclusions Failure to reinitiate ART within 18 months was common in this sample. Care engagement was associated with greater ART reinitiation.

The Relationship

Background: Although Lesotho has one of the highest childhood mortality levels in Southern Africa, there has been limited research on the link between type of birth attendant and neonatal mortality in Lesotho. This study examined the relationship between type of birth attendant and neonatal mortality while controlling for socio-demographic characteristics of mothers in LesothoMethods: The study used data from the children’s file of 2014 Lesotho Demographic and Health Survey data. Kaplan-Meier method was used to estimate neonatal mortality rate and Cox proportional hazard regression model was used to assess the association between type of birth attendant and neonatal mortality.Results: Result shows that 5.3% of all births attended to by non-SBAs resulted into neonatal mortality compared to 2.8% of those attended to by SBA. Result further shows that regardless of socio-demographic characteristics, the risks of neonatal mortality were significantly higher with non-SBAs compared to SBA in Lesotho (HR: 2.00, CI: 1.31-3.06).Conclusion: The risk of neonatal mortality is two times higher among children delivered by Non-SBA. Scale-up in access and uptake of SBA is recommended in Lesotho. Thus, Policy on scale-up access to SBA at delivery at no costs need to be put in place. Keywords: Neonatal; mortality; Lesotho.

Pendahuluan. Pengaruh revaskularisasi terhadap kesintasan pasien non ST elevation myocardial infarction (NSTEMI) masih belum jelas. Waktu revaskularisasi yang optimal pada pasien NSTEMI belum ditemukan. Penelitian ini bertujuan mengetahui pengaruh revaskularisasi terhadap kesintasan pasien NSTEMI, juga mengetahui pengaruh waktu revaskularisasi terhadap kesintasan pasien NSTEMI.Metode. Penelitian dengan disain kohort retrospektif dilakukan terhadap 300 pasien non ST elevation myocardial infarction yang dirawat di RSUPNCM pada kurun waktu Desember 2006-Maret 2011. Data klinis, laboratorium, elektrokardiografi (EKG), ekokardiografi, dan angiografi koroner dikumpulkan. Pasien yang telah terhitung enam bulan setelah onset kemudian dihubungi melalui telepon untuk melihat status mortalitasnya. Perbedaan kesintasan revaskularisasi ditampilkan dalam kurva Kaplan Meier dan perbedaan kesintasan diantara dua kelompok diuji dengan Log-rank test dengan batas kemaknaan <0,05, serta analisis multivariat dengan Cox proportional hazard regression untuk menghitung adjusted hazard ratio (dan interval kepercayaan 95%) antara pasien NSTEMI yang menjalani terapi medikamentosa dan revaskularisasi terhadap kelompok medikamentosa dengan memasukkan variabel perancu.Hasil. Terdapat perbedaan kesintasan yang bermakna pada uji log rank (p<0,001) antara pasien NSTEMI yang menjalani revaskularisasi dan terapi medikamentosa saja dengan crude HR 0,19 (IK95% 0,11-0,34) dan fully adjusted HR 0,33 (IK95% 0,17-0,64). Faktor perancu yang bermakna adalah penurunan fungsi ginjal dan syok kardiogenik. Pada analisis kesintasan berdasarkan waktu revaskularisasi tidak didapatkan perbedaan kesintasan antara pasien yang menjalani revaskularisasi < 1 minggu, 1-2 minggu, 2-3 minggu, 3-4 minggu, 4-5 minggu dengan p=0,853.Simpulan. Kesintasan enam bulan pasien NSTEMI yang menjalani terapi medikamentosa dan revaskularisasi lebih baik dibandingkan dengan terapi medikamentosa saja. Tidak terdapat perbedaan kesintasan enam bulan pasien NSTEMI berdasarkan waktu revaskularisasi.

CONTEXT: Promotion of breastfeeding in Brazilian maternity hospitals. OBJECTIVE: To quantify changes in the breastfeeding duration among mothers served by hospitals exposed to the Wellstart-SLC course, comparing them with changes among mothers attended by institutions not exposed to this course. DESIGN: Randomized Institutional Trial. SETTING: The effects of training on breastfeeding duration was assessed in eight Brazilian hospitals assigned at random to either an exposed group (staff attending the Wellstart-SLC course) or a control group. SAMPLE: For each of the eight study hospitals, two cohorts of about 50 children were visited at home at one and six months after birth. The first cohort (n = 494) was composed of babies born in the month prior to exposure to the Wellstart-SLC course, and the second cohort (n = 476) was composed of babies born six months subsequent to this exposure. MAIN MEASUREMENTS: Kaplan-Meier curves were plotted to describe the weaning process and log-rank tests were used to assess statistical differences among survival curves. Hazard ratio (HR) estimates were calculated by fitting Cox proportional hazard regression models to the data. RESULTS: The increases in estimated, adjusted rates for children born in hospitals with trained personnel were 29% (HR = 0.71) and 20% (HR = 0.80) for exclusive and full breastfeeding, respectively. No changes were identified for total breastfeeding. CONCLUSION: This randomized trial supports a growing body of evidence that training hospital health professionals in breastfeeding promotion and protection results in an increase in breastfeeding duration.
