Kashgar, located in Xinjiang, China has a high incidence of tuberculosis (TB) making prevention and control extremely difficult. In addition, there have been very few prediction studies on TB incidence here. We; therefore, considered it a high priority to do prediction analysis of TB incidence in Kashgar, and so provide a scientific reference for eventual prevention and control.

Time series study.

Kashgar, China.

We used a single Box-Jenkins method and a Box-Jenkins and Elman neural network (ElmanNN) hybrid method to do prediction analysis of TB incidence in Kashgar. Root mean square error (RMSE), mean absolute error (MAE) and mean absolute percentage error (MAPE) were used to measure the prediction accuracy.

After careful analysis, the single autoregression (AR) (1, 2, 8) model and the AR (1, 2, 8)-ElmanNN (AR-Elman) hybrid model were established, and the optimal neurons value of the AR-Elman hybrid model is 6. In the fitting dataset, the RMSE, MAE and MAPE were 6.15, 4.33 and 0.2858, respectively,on scale-dependent measures (RMSE, MAE and MAPE) in the AR (1, 2, 8) model were inferior to those in the AR-Elman hybrid model, which indicated that the AR-Elman hybrid model was better than the AR (1, 2, 8) model. The Box-Jenkins and ElmanNN hybrid method therefore can be highlighted in predicting the temporal trends of TB incidence in Kashgar, which may act as the potential for far-reaching implications for prevention and control of TB.

To identify the prevalence of stage B heart failure (SBHF) in patients with type 2 diabetes mellitus (T2DM) with no history of cardiovascular disease (CVD).

Observational study.

A single-centre study in which eligible patients were recruited from T2DM clinic. Following consent, patients completed a questionnaire and underwent physical examinations. Patients had blood drawn for laboratory investigations and had a transthoracic echocardiography.

A total of 305 patients who were not known to have CVD were recruited. Patients with deranged liver function tests and end stage renal failure were excluded.

Echocardiographic parameters such as left ventricular ejection fraction, left ventricular mass index (LVMI), left ventricular hypertrophy, left atrial enlargement and diastolic function were examined.

A total of 305 patients predominantly females (65%), with mean body mass index of 27.5 kg/m

participated in this study. None of them had either a history or signs and symptoms of CVD. Seventy-seven percent of patients had a history of hypertension and 83% of this study population had T2DM for more than 10 years. Mean HbA1c of 8.3% was recorded. Almost all patients were taking metformin. Approximately, 40% of patients were on newer anti-T2DM agents such as sodium-glucose cotransporter-2 and dipeptidyl peptidase 4 inhibitors. Fifty-seven percent (n=174) of the study population had SBHF at the time of study diastolic dysfunction, increased LVMI and increased left atrial volume index (LAVI) were noted in 51 patients (17%), 128 patients (42%) and 98 patients (32%), respectively. Thirty-seven patients (12%) had both increase LVMI and LAVI.

Our study has revealed a high prevalence of SBHF in T2DM patients without overt cardiac disease in Malaysia that has one of the highest prevalence of TDM in the world.

We aimed to estimate the gender-specific prevalence and associated factors of hypertension among elderly people in Bangladesh.

We analysed data from the food security and nutrition surveillance round 2018-2019. The multistage cluster sampling method was used to select the study population. Hypertension was defined as systolic blood pressure ≥140 mm Hg and/or diastolic blood pressure ≥90 mm Hg and/or having a history of hypertension. We carried out the descriptive analysis, bivariate and multivariable logistic regression to report the weighted prevalence of hypertension as well as crude and adjusted ORs with 95% CI. A p value<0.05 was considered statistically significant.

The study was conducted in 82 clusters (57 rural, 15 non-slum urban and 10 slums) in all eight administrative divisions of Bangladesh.

A total of 2482 males and 2335 females aged ≥60 years were included in this analysis.

The weighted prevalence of hypertension was 42% and 56% among males and females, respectively. The prevalence es for elderly population.

In Bangladesh, half of the elderly persons were hypertensive, with a higher prevalence in females. In both sexes, odds of hypertension was higher among persons with older age (≥70 years), insufficient physical activity, higher waist circumference and self-reported diabetes. The Ministry of Health of Bangladesh should consider these findings while designing and implementing health programmes for elderly population.In persistent pulmonary hypertension of the newborn (PPHN), the ratio of pulmonary vascular resistance to systemic vascular resistance is increased. Extrapulmonary shunts (patent ductus arteriosus and patent foramen value) allow for right-to-left shunting and hypoxaemia. (R,S)-3,5-DHPG ic50 Systemic hypotension can occur in newborns with PPHN due to variety of reasons, such as enhanced peripheral vasodilation, impaired left ventricular function and decreased preload. Systemic hypotension can lead to end organ injury from poor perfusion and hypoxaemia in the newborn with PPHN. Thus, it must be managed swiftly. However, not all newborns with PPHN and systemic hypotension can be managed the same way. Individualised approach based on physiology and echocardiographic findings are necessary to improve perfusion to essential organs. Here we present a review of the physiology and mechanisms of systemic hypotension in PPHN, which can then guide treatment.

Heart rate (HR) is used to guide interventions during delivery room (DR) neonatal resuscitation. Dry electrode ECG (NeoBeat) may detect HR more rapidly than pulse oximetry (PO) and portable ECG, but real-time comparisons of these devices are lacking.

PO, ECG and NeoBeat were placed sequentially on newborns in the DR. Time for device placement and time to accurate HR acquisition were noted.

DR resuscitations of 28 preterm/term infants were observed. The NeoBeat was placed faster (ie, 3 s) than PO (20 s, p=<0.0001) and ECG (16 s, p=<0.0001). Total time from initiation of device placement to HR acquisition was fastest with NeoBeat (13 s) versus ECG (42 s, p<0.0001) and PO (105 s, p<0.0001) (duration values=median).

These observations in a small cohort of relatively well neonates demonstrate that the NeoBeat is significantly faster to place and consistently acquires HR faster than PO and ECG.

Determine risk of death or neurodevelopmental impairment (NDI) in infants with late-onset sepsis (LOS) versus late-onset, antibiotic-treated, blood culture-negative conditions (LOCNC).

Retrospective cohort study.

24 neonatal centres.

Infants born 1/1/2006-31/12/2014, at 22-26 weeks gestation, with birth weight 401-1000 g and surviving >7 days were included. Infants with early-onset sepsis, necrotising enterocolitis, intestinal perforation or both LOS and LOCNC were excluded.

LOS and LOCNC were defined as antibiotic administration for ≥5 days with and without a positive blood/cerebrospinal fluid culture, respectively. Infants with these diagnoses were also compared with infants with neither condition.

Death or NDI was assessed at 18-26 months corrected age follow-up. Modified Poisson regression models were used to estimate relative risks adjusting for covariates occurring ≤7 days of age.

Of 7354 eligible infants, 3940 met inclusion criteria 786 (20%) with LOS, 1601 (41%) with LOCNC and 1553 (39%) with neither. Infants with LOS had higher adjusted relative risk (95% CI) for death/NDI (1.14 (1.05 to 1.25)) and death before follow-up (1.71 (1.44 to 2.03)) than those with LOCNC. Among survivors, risk for NDI did not differ between the two groups (0.99 (0.86 to 1.13)) but was higher for LOCNC infants (1.17 (1.04 to 1.31)) compared with unaffected infants.

Infants with LOS had higher risk of death, but not NDI, compared with infants with LOCNC. Surviving infants with LOCNC had higher risk of NDI compared with unaffected infants. Improving outcomes for infants with LOCNC requires study of the underlying conditions and the potential impact of antibiotic exposure.

Describe the current practice of family presence during neonatal tracheal intubations (TIs) across neonatal intensive care units (NICUs) and examine the association with outcomes.

Retrospective analysis of TIs performed in NICUs participating in the National Emergency Airway Registry for Neonates (NEAR4NEOS).

Thirteen academic NICUs.

Infants undergoing TI between October 2014 and December 2017.

Association of family presence with TI processes and outcomes including first attempt success (primary outcome), success within two attempts, adverse TI-associated events (TIAEs) and severe oxygen desaturation ≥20% from baseline.

Of the 2570 TIs, 242 (9.4%) had family presence, which varied by site (median 3.6%, range 0%-33%; p<0.01). Family member was more often present for older infants and those with chronic respiratory failure. Fewer TIs were performed by residents when family was present (FP 10% vs no FP 18%, p=0.041). Among TIs with family presence versus without family presence, the first attempt success rate was 55% vs 49% (p=0.062), success within two attempts was 74% vs 66% (p=0.014), adverse TIAEs were 18% vs 20% (p=0.62) and severe oxygen desaturation was 49% vs 52%, (p=0.40). link2 In multivariate analyses, there was no independent association between family presence and intubation success, adverse TIAEs or severe oxygen desaturation.

Family are present in less than 10% of TIs, with variation across NICUs. Even after controlling for important patient, provider and site factors, there were no significant associations between family presence and intubation success, adverse TIAEs or severe oxygen desaturation.

To assess the association between routinely prescribed non-steroidal anti-inflammatory drugs (NSAIDs) and deaths from COVID-19 using OpenSAFELY, a secure analytical platform.

We conducted two cohort studies from 1 March to 14 June 2020. Working on behalf of National Health Service England, we used routine clinical data in England linked to death data. In study 1, we identified people with an NSAID prescription in the last 3 years from the general population. In study 2, we identified people with rheumatoid arthritis/osteoarthritis. We defined exposure as current NSAID prescription within the 4 months before 1 March 2020. We used Cox regression to estimate HRs for COVID-19 related death in people currently prescribed NSAIDs, compared with those not currently prescribed NSAIDs, accounting for age, sex, comorbidities, other medications and geographical region.

In study 1, we included 536 423 current NSAID users and 1 927 284 non-users in the general population. link3 We observed no evidence of difference in risk of COVID-19 related death associated with current use (HR 0.
