Energy storage and transportation are essential keys to make sure the continuity of energy to the customer. Electric power generation is changing dramatically across the world due to the environmental effects of Greenhouse gases (GHG) produced by fossil fuels. The unpredictable daily and seasonal variations in demand for electrical energy can be tackled by introducing the energy storage systems (ESSs) and hence mitigating the extra GHG emission in the atmosphere. Energy storage techniques can be mechanical, electro‐chemical, chemical, or thermal, and so on. The most popular form of energy storage is hydraulic power plants by using pumped storage and in the form of stored fuel for thermal power plants. The classification of ESSs, their current status, flaws and present trends, are presented in this article. The present state of fossil fuel reserves, their production, consumption, and as a consequence of these the CO2 emissions are also discussed. The primary energy carriers coal, oil and gas are not evenly distributed along the globe. Long distances are involved in transporting these energy carriers and transportation and delivery of these key resources to the prime customers is always necessary. The different methods to transport the energy from the source end to demand end is also discussed in this article. The assessment of various energy storage methods on the basis of several factors and present status and development of storage and transportation of energy in Pakistan is discussed.

Background Clostridioides difficile infection (CDI) Laboratory (Lab) identified (ID) events are reportable to CMS through the CDC’s NHSN. Prevention of transmission has been the main component of interventions; however, avoiding false-positive laboratory diagnoses can also lead to decreased incidence.MethodsA retrospective analysis of HO-CDI Lab-ID events was conducted to evaluate the results of a series of interventions at the University of Alabama Hospital, a 1150-bed tertiary care center in Birmingham, AL. The study period was from the first quarter of 2013 (1Q 2013) until 1Q of 2019. Interventions were implemented in sequential order were: (i) CDI prevention bundle education (3Q 2014); (ii) two-step laboratory testing algorithm (2Q 2015); (iii) selective enhanced environmental disinfection on oncology units (2Q 2016); (iv) diagnostic stewardship by reminding providers to reconsider testing if the patient received a laxative within 48 hours (4Q 2016).ResultsAt the beginning of the study period, the HO CDI Lab ID Event SIR was 0.96. The standard infection ratio (SIR) over the time period is shown in Figure 1. We observed a slight decrease in HO-CDI Lab ID event SIR after implementation of the CDI prevention bundle (0.96 vs. 0.77). A change in the diagnostic testing from PCR-based to a two-step algorithm (EIA testing for GDH and Toxin confirmed by PCR) resulted in a slight increase although not statistically significant (0.77 vs. 0.83). A downward trend was observed when selective enhanced terminal disinfection with hydrogen peroxide vapor was performed on all oncology patient rooms vacated by patients with CDI (0.83 vs. 0.72). The largest and sustained impact was observed after implementation of a computer-assisted diagnostic stewardship in which providers were reminded if the patient was administered any stool softener or laxative within 48 hours of the order for CDI testing (0.72 vs. 0.32). The institutions SIR value became significant in 2Q 2016 (P = 0.0014) and significance was maintained since that time. The difference between expected and observe HO-CDI Lab ID events is demonstrated in Figure 2.ConclusionThrough a series of interventions, we observed a decrease in HO-CDI event rates. Diagnostic stewardship with academic detailing resulted in the most impactful and sustained improvement. Disclosures All authors: No reported disclosures.

Background Stillbirths are reported as one of the most neglected tragedies in global health, with around 2m stillbirths occurring annually and the majority occurring in low- and middle income countries (LMICs). Many antenatal stillbirths are due to preventable conditions such as maternal infections and non-communicable diseases. Almost half of all stillbirths occur during the intrapartum period, with many linked to obstetric complications. Known risk factors for stillbirths overall include young or advancing maternal age, fetal infection, maternal hypertensive conditions, perinatal asphyxia, history of previous stillbirth, obstetric complications, intrauterine growth restriction and abruptio placenta/placenta praevia. Common non-clinical risk factors include lack of education, socioeconomic deprivation and substandard antenatal care. Methods A single site prospective observational study conducted over three-months was conducted in a tertiary referral hospital in Kano, Nigeria. Eligible participants were mothers presenting at the site in labour and their babies. Demographic and clinical data were collected by paper-based questionnaires. Data were collected on living environment, health and medical history, pregnancy history and pregnancy/birth factors. Each mother answered pre-delivery questions, with potential follow-on questions dependent on birth outcome. Further data points were collected from clinical observations. Photographs were taken of stillborn babies to support data collected and to aid the UK team on classifying degrees of maceration in an attempt to identify antenatal and intrapartum fetal death. Findings Higher odds of stillbirth were associated with low levels of education, a further distance to travel from home to the hospital, living in a shack, maternal hypertension and having had a previous stillbirth after adjusting for all sociodemographic and health features. Higher odds of intrapartum stillbirth included; shoulder presentation, compound presentation and breech presentation compared to cephalic presentation. Other birth related factors associated with higher odds of stillbirth included reported birthing complications, duration of labour being >=18 hours), antepartum haemorrhage, prolonged/obstructed labour, vaginal breech delivery, emergency Caesarean-section delivery, and signs of trauma to the neonate. ConclusionsIdentified risk factors associated with stillbirths are relatively amenable to intervention and a lot of work has been conducted globally, so the development of intervention with sufficient funding should be a relatively rapid process.
