Increased frailty is associated with risk of hospital-acquired infections and death during heart failure hospital admissions

Abstract Background Frailty is common in patients admitted with acute decompensation of heart failure (ADHF) and it is unclear how the frailty syndrome affects heart failure (HF) patients during their acute hospital admission. Understanding the interplay between frailty, impaired renal function, hospital-acquired infections (HAI), and death may be useful in optimising patient care and prognosis. Purpose The aim of this analysis was to explore the relationship between admission frailty levels and the incidence of HAI, acute kidney injury (AKI), and mortality in acute HF hospital admissions. Methods This is a retrospective analysis of data submitted from a single centre to the National HF audit between January and June 2023. Additional frailty and baseline renal function data was retrospectively collected from electronic patient health records. Patients were categorised into three groups according to their Rockwood Clinical Frailty Scale (CSF) (1): no/mild frailty (CFS 1-3), moderate frailty (CFS 4-6) and severe frailty (CFS 7-9). AKI was defined based on baseline and admission creatinine, as per KDIGO guidelines (2). Chi-squared and t-tests were used to compare baseline characteristics between frailty groups. Chi-squared tests were used to compare frailty groups in terms of: HAI, AKI, mortality. Results Between 1st January and 22nd June 2023, there were 344 acute HF hospital admissions in our centre. Most patients had moderate frailty on admission (n=256, 74.4%). Frail patients were significantly older, had a lower admission mean haemoglobin and more were female, compared to non-frail patients (Figure 1A). Patients who were more frail were more likely to experience HAI during their admission; p=0.035 (figure 1B). Furthermore, patients with HAI had a greater risk of mortality, at a median follow-up of 171 (IQR 100.25) days after admission, compared to those without HAI (p>0.001). 41.9% of acute HF admissions were associated with an AKI, and although numerically more frail patients had an AKI, this did not achieve statistical significance (p=0.084). Patients who were more frail were more likely to die, both during hospital admission and at 3 months following discharge; p<0.001 (Figure 1B). Furthermore, this trend persisted after follow-up; p<0.001 (Figure 2). Conclusions Patients with moderate or severe frailty are at greater risk of adverse events (HAI, death) during an acute HF hospital admission, than patients with no or mild frailty. It is imperative to consider the frailty status of all patients with ADHF, to be aware of the frailty-associated risks, and act proactively with targeted interventions (screen for infections, daily bloods, early conversations with patients and their families about treatment escalation plans and patient priorities) to improve outcomes and enhance the quality of care for this vulnerable patient population. Further research is warranted to explore potential interventions to address frailty-related risks in HF management.

Shifts in Maritime Trade Routes as a Result of Red Sea Shipping Crisis Detected in TROPOMI NO2 Data

AbstractObservations from space‐borne spectrometers have been lately used to quantify shipping emissions of nitrogen oxides (ΝΟΧ). Here we present a method that enhances the shipping signal of NO2 TROPOspheric MOnitoring Instrument (TROPOMI) satellite sensor observations in order to assess the impact of the Red Sea ship attacks on NO2 levels in three important shipping routes along the Red Sea, the Cape of Good Hope, and the Gibraltar Strait. Major shipping carriers, sailing usually via the Red Sea, have responded to the attacks by transiting their fleet around the African continent. The shipping signal from TROPOMI declines by ∼55% in the Red Sea and ∼15% in the Gibraltar Strait while an increase of ∼40% is found off the South African coast between January–June 2024 and the same period in 2023. These changes correlate well with vessel statistics, demonstrating the ability to track abrupt changes in NO2 shipping levels with satellite measurements.

Retrospective study of cisplatin plus radiotherapy toxicities in locally advanced squamous cell carcinoma of the head and neck - ReCisTT study.

Squamous cell carcinoma of the head and neck (SCCHN) is a multifactorial disease involving genetic and environmental factors representing one of the most frequent cancer-related deaths worldwide. Tobacco and alcohol use account for most SCCHN, while a growing subset of oropharyngeal cancers is causally associated with human papillomavirus (HPV) infection. Despite improvements in overall survival, patients with HPV-negative locally advanced (LA) SCCHN continue to have a poor prognosis. For these patients, the standard of care is radiotherapy with concurrent chemotherapy (RCT). This retrospective, multicenter, and observational study analyzed the treatment compliance of 326 patients with LA-SCCHN who underwent RCT between January 1st, 2014, and June 30th, 2017. This study also evaluated the potential factors associated with treatment compliance, the compliance impact on clinical response, and the main toxicities experienced by patients. A total of 274 (84%) patients were compliant and received the planned dose of cisplatin. Overall, 957 adverse events were reported in 98.2% of patients during the study. The overall response rate was 80.2%, with 60.4% of patients achieving a complete response. Despite the high treatment compliance, 62.6% of adverse events reported were related to cisplatin. Identifying risk factors associated with non-compliance could enable physicians to identify ineligible patients for cisplatin-based RCT and prevent patients from receiving inadequate treatment leading to severe adverse events..

Evolution of EEG Findings in Patients with Acute Brain Injury.

Increasing use of continuous EEG monitoring (cEEG) provides the opportunity to observe temporal trends in EEG patterns during the acute phase of brain injury. These trends have not been extensively documented. We conducted a retrospective chart review of patients undergoing cEEG between January 1st and June 30th, 2019, at two academic medical centers. Only patients with acute brain injury having electrographic or electroclinical seizures or epileptic EEG findings on day one of monitoring and ≥ two calendar days of cEEG were included. The temporal evolution of EEG patterns was depicted as a heatmap. Of 1356 screened patients, 101 met the study criteria. Clinical acute symptomatic seizures occurred in 30 patients (29.7%) prior to EEG. The median number of days of cEEG was four (IQR 3-6). Amongst patients with electrographic seizures, status epilepticus, generalized periodic discharges, or sporadic epileptiform discharges, 24.6% had improvement and 54.1% had resolution of epileptic EEG findings by the final day of monitoring. In contrast, 65% with lateralized periodic discharges or lateralized rhythmic delta activity persisted or worsened. Overall, 61.4% (62/101) showed either improvement (19.8%) or resolution (41.6%) of their EEG findings prior to hospital discharge. Of the 36 patients with follow-up EEGs at a median of 4.5 (IQR 3-8) months after admission for acute brain injury, 83% (30/36) showed either improvement (1/36; 2.7%) or resolution (29/36; 80.6%). We observed a trend towards normalization of most epileptiform patterns except LPDs and LRDA, over time in patients with acute brain injury. The clinical significance of this trend as it relates to antiseizure medication treatment and neurologic outcomes warrants further investigation in an independent cohort.

Incubation Periods of SARS-CoV-2 Wild-Type, Delta, and Omicron Variants–Dominant Periods in Singapore

This study in Singapore analysed the incubation periods of the following SARS-CoV-2 variants: Wuhan-Hu-1, Delta, and Omicron. Three pandemic waves were examined: Wuhan-Hu-1 (January 2020–March 2021), Delta (May–October 2021), and Omicron (January–June 2022). Data from the SingHealth COVID-19 registry, covering patients from 23 January 2020 to 10 June 2022, were used to calculate incubation periods during the three time periods. The study found median incubation periods of 11 days for Wuhan-Hu-1, 3 days for Delta, and 3 days for Omicron (p-value: <0.001). This study highlighted the impact of different containment measures and the importance of robust EMR systems for tracking and managing infectious diseases. Key challenges included accurate contact tracing and IT infrastructure capabilities. The findings support the use of EMR data for future infectious disease preparedness in Singapore.

A Retrospective Study of Pattern of Abnormal Findings in Routine Screening Investigations Done of Psychiatry Inpatients in Tertiary Care Teaching Hospital

Abstract Introduction: Physical comorbidity in persons with mental illness is a rule rather than exception. Hence, regular screening investigations in psychiatry inpatients help to detect physical illness at early stage. Aims and Objectives: The aim of this study was to evaluate the results of various screening investigations, referral patterns, and physical comorbidities in psychiatric inpatient records. Methodology: This was a descriptive, analytical, record-based study conducted in the psychiatry department of a tertiary care teaching hospital, wherein case notes of all inpatients admitted to the psychiatry unit during 6 months (January–June 2023) were studied. Inpatient records were evaluated for sociodemographic details, indication for admission, investigations as needed, any physical comorbidity, treatment history, referral patterns, and their outcomes. Records with incomplete details and known physical illnesses mentioned were excluded. Results: Total 100 patients’ records (63 males; mean age = 35 years, 37 females; mean age = 41 years) were included in the study. The common diagnosis was mood disorder 36% (n = 36), followed by substance use disorder 30% (n = 30) and schizophrenia 22% (n = 22). On evaluating investigations, abnormalities found were anemia, diabetes mellitus, hypertension, and thyroid disease (42% [n = 42/100], 24% [n = 24/100], 22% [n = 22/100], and 22% [n = 22/100], respectively). Magnetic resonance imaging (MRI) brain changes were seen in 75% of patients with acute behavior disturbances (n = 4) and MRI spine changes in all major depressive disorder patients presented with backache (n = 4). Ultrasonography abdomen findings were abnormal in 68% (n = 26/38), of which 80% (n = 21/26) had substance use disorder. For the management of abnormal findings, the referral consultation rate was 76% (n = 76/100); 86% (n = 66/76) of patients required more than one consultation with total 154 referrals. Conclusions: The investigations as indicated help in early detection and management of physical illness which mostly remains out of sight due to psychiatry illness.

Patellar tendon restoration techniques: a systematic review of outcomes for repair and reconstruction methods.

This systematic review aims to delineate the various methods to repair or reconstruct the patellar tendon using the available literature. MEDLINE and PubMed electronic databases were searched for English language clinical studies involving patellar tendon rupture repair or reconstruction that reported patient-reported outcome scores (PROS) between January 1st, 1953 and June 17th, 2021. Data was extracted on full text articles to collect functional outcome scores and rupture category, including acute, chronic, post-total knee arthroplasty (TKA) and post-anterior cruciate ligament reconstruction (ACLR). Twenty-three studies with a total of 738 patients were included. Of the 14 studies including acute repairs, mean postoperative Lvsholm scores ranged from 84 to 99.5. Knee Society Score (KSS) and knee range of motion (ROM) measurement were the most widely reported outcomes in the chronic setting. The average postoperative KSS scores ranged from 70 to 87.7. Of the six studies that included patellar tendon repairs/reconstructions in the setting of prior TKA, the most frequently reported outcomes were KSS scores and knee ROM measurements. The average postoperative KSS scores for the three cohorts reporting reconstruction with allograft ranged from 79 to 88 as compared to the average postoperative KSS score for reconstruction with autograft of 70. Despite this heterogeneity, we concluded: (1) in the primary setting, cerclage augmentation yields the lowest lysholm scores and should not be considered, although primary repairs with and without augmentation yield comparable postoperative lysholm scores, (2) in the chronic setting, repair with augmentation and reconstruction yielded similar results aside from in post-TKA patients where allograft reconstruction yielded superior KSS scores.

Evaluation of interventions to improve timely hepatitis B birth dose vaccination among infants and maternal tetanus vaccination among pregnant women in Nigeria

Background: Nigeria has the largest number of children infected with hepatitis B virus (HBV) globally and has not yet achieved maternal and neonatal tetanus elimination. In Nigeria, maternal tetanus diphtheria (Td) vaccination is part of antenatal care and hepatitis B birth dose (HepB-BD) vaccination for newborns has been offered since 2004. We implemented interventions targeting healthcare workers (HCWs), community volunteers, and pregnant women attending antenatal care with the goal of improving timely (within 24 hours) HepB-BD vaccination among newborns and Td vaccination coverage among pregnant women. Methods: We selected 80 public health facilities in Adamawa and Enugu states, with half intervention facilities and half control. Interventions included HCW and community volunteer trainings, engagement of pregnant women, and supportive supervision at facilities. Timely HepB-BD coverage and at least two doses of Td (Td2+) coverage were assessed at baseline before project implementation (January–June 2021) and at endline, one year after implementation (January–June 2022). We held focus group discussions at intervention facilities to discuss intervention strengths, challenges, and improvement opportunities. Results: Compared to baseline, endline median vaccination coverage increased for timely HepB-BD from 2.6% to 61.8% and for Td2+ from 20.4% to 26.9% in intervention facilities (p < 0.05). In comparison, at endline in control facilities median vaccination coverage for timely HepB-BD was 7.9% (p < 0.0001) and Td2+ coverage was 22.2% (p = 0.14). Focus group discussions revealed that HCWs felt empowered to administer vaccination due to increased knowledge on hepatitis B and tetanus, pregnant women had increased knowledge that led to improved health seeking behaviors including Td vaccination, and transportation support was needed to reach those in far communities. Conclusion: Targeted interventions significantly increased timely HepB-BD and Td vaccination rates in intervention facilities. Continued support of these successful interventions could help Nigeria reach hepatitis B and maternal and neonatal tetanus elimination goals.

Isolation of Potential Antagonistic Rhizosphere Fungi against Alternaria alternata from Organic Carrot Productions

Rhizospheric fungi can have serve as biological agents against plant pathogens Alternaria alternata, which infects carrot plants. Rhizospheric fungi are more abundant in organic lands. This study aims to isolate fungi from organic carrot’s rhizosphere that are able to suppress A. alternata’s growth and determine isolate rhizospheric fungi ability to inhibit A. alternata to identify potential biological control agents against A. alternata. This research was conducted at the Laboratory of Biotechnology and Basic Biology, Diponegoro University, between January–June 2023. Research methods include survey location, soil sampling, rhizospheric fungi isolation, pathogenic fungi isolation, creating growth curve, pathogenicity tests, antagonism tests, and fungi identification. This study used a complete randomized design (CRD) and was analyzed using ANOVA at the 5% level of significance and Duncan's hoc-posttest. Fungi isolation from organic carrot plant’s rhizosphere resulted in 13 isolates consisting of six genera: Penicillium, Aspergillus, Paecilomyces, Myrothecium, Trichoderma, and Simplicillium. The antagonism test showed that eight antagonistic isolates, including the genus Penicillium (WO1, WO6, WO10), Paecilomyces (WO5), Myrothecium (WO7), Trichoderma (WO9), and Aspergillus (WO11, WO13), where WO1, WO6, WO10, and WO11 have a medium percentage of inhibition (44.12-57.84%), while WO5, WO7, WO9, and WO13 have a high percentage of inhibition (64.29-76.06%). The eight isolates showed antagonism mechanisms, including antibiosis (WO1, WO5, WO6, WO7, WO10, and WO11) and parasitism (WO9 and WO13).

CACM-Net: Daytime Cloud Mask for AGRI Onboard the FY-4A Satellite

Accurate cloud detection is a crucial initial stage in optical satellite remote sensing. In this study, a daytime cloud mask model is proposed for the Advanced Geostationary Radiation Imager (AGRI) onboard the Fengyun 4A (FY-4A) satellite based on a deep learning approach. The model, named “Convolutional and Attention-based Cloud Mask Net (CACM-Net)”, was trained using the 2021 dataset with CALIPSO data as the truth value. Two CACM-Net models were trained based on a satellite zenith angle (SZA) &lt; 70° and &gt;70°, respectively. The study evaluated the National Satellite Meteorological Center (NSMC) cloud mask product and compared it with the method established in this paper. The results indicate that CACM-Net outperforms the NSMC cloud mask product overall. Specifically, in the SZA &lt; 70° subset, CACM-Net enhances accuracy, precision, and F1 score by 4.8%, 7.3%, and 3.6%, respectively, while reducing the false alarm rate (FAR) by approximately 7.3%. In the SZA &gt; 70° section, improvements of 12.2%, 19.5%, and 8% in accuracy, precision, and F1 score, respectively, were observed, with a 19.5% reduction in FAR compared to NSMC. An independent validation dataset for January–June 2023 further validates the performance of CACM-Net. The results show improvements of 3.5%, 2.2%, and 2.8% in accuracy, precision, and F1 scores for SZA &lt; 70° and 7.8%, 11.3%, and 4.8% for SZA &gt; 70°, respectively, along with reductions in FAR. Cross-comparison with other satellite cloud mask products reveals high levels of agreement, with 88.6% and 86.3% matching results with the MODIS and Himawari-9 products, respectively. These results confirm the reliability of the CACM-Net cloud mask model, which can produce stable and high-quality FY-4A AGRI cloud mask results.

Prevalence of Neospora caninum and associated risk factors in semi-intensive female water buffaloes reared in Greece, using an ELISA kit on milk samples

Neospora caninum is an apicomplexan (family: Sarcocystidae) protozoan parasite with a global distribution. In the N. caninum life cycle, dogs and other related canids are the definitive hosts, while other animals such as water buffaloes (Bubalus bubalis) constitute the intermediate host for this parasite. In many countries, the water buffalo is of high economic importance, providing valuable high-quality products for human needs. Although knowledge concerning the prevalence of this parasite in intermediate animal host populations is crucial, data from water buffalo are scarce. Keeping this in mind, the aim of this study was to examine the presence and assess the prevalence rates of N. caninum infection in water buffaloes in Northern Greece, where this animal husbandry sector started to raise, as well as to determine associated risk factors, with the application of a commercially available Neospora ISCOM ELISA test kit, developed for the detection of antibodies against N. caninum in milk samples The study was conducted during January–June 2023 in a total of 172 individual raw milk samples, collected from dairy buffaloes, reared under a semi extensive system, in three different farms. Information on the status of N. caninum infection in buffaloes from Greece was so far unknown with a lack of epidemiological or risk factors associated. For the detection of N. caninum, the commercially available Neospora ISCOM ELISA test kit (SANOVIR ®, Svanova Biotech AB, Uppsala, Sweden) was utilized. Results demonstrated the presence of N. caninum in water buffaloes from Greece for the first time. All positive N. caninum animal were asymptomatic, with absence of any disease signs. The overall prevalence of infection was 22.10%, whereas the main risk factors include the presence of dogs as well as the low biosecurity measures.

#837 Information needs and emotional impact when receiving a diagnosis of chronic kidney disease: insights from DISCOVER CKD

Abstract Background and Aims Chronic kidney disease (CKD) is often a silent condition, with symptoms typically not appearing until a large proportion of kidney function has been lost. Therapeutic interventions, e.g., disease-modifying medications, blood pressure and diabetes control, and lifestyle changes, can delay CKD progression, particularly if instigated early. However, psychological distress can reduce adherence to interventions. It is important patients are adequately informed about their diagnosis to improve adherence and reduce the impact of distress. Multinational, real-world data on patient experiences with CKD, particularly about clinical management, treatment patterns and quality of life, are limited. This DISCOVER CKD sub-study aimed to capture the emotions elicited by patients at CKD diagnosis and their perceptions of the information received. Method DISCOVER CKD (NCT04034992) is a multinational cohort study that aims tocharacterise the epidemiology of CKD and describe patient characteristics, CKD progression, clinical outcomes, the patient journey, practice patterns, and clinical management. The current analysis includes a subset of patients from the USA, UK, Japan, and Spain, who participated in 1-2-1 telephone interviews about their CKD experience, including their disease journey and interactions with the healthcare system. Interview topics in DISCOVER CKD were informed by a pilot study that utilised data from PatientsLikeMe, an online network for patients to share personal stories and health data. Qualitative interviews, conducted in the local language by trained interviewers, January–June 2023, lasted ∼60–90 minutes. Transcribed interviews were translated into English for coding (MAXQDA Plus 2022 v22.3.0) and analysis. The study received research ethics board approval and all participants provided written informed consent. Results 103 patients (mean age 63.1 years; 42.7% female; 51.5% with type 2 diabetes) were interviewed. Most had CKD stage 3A (22.3%) or 3B (28.2%); 26.2% had stage 4 or 5 no dialysis and 9.7% were stage 4 (n = 1) or 5 on dialysis. Average time since diagnosis was 9.5 years. Over one-third (38.8%; n = 40/103) of participants did not recall any specific symptoms or signs of CKD prior to diagnosis. Of the pre-diagnosis symptoms reported, the most common was fatigue (21.4%; n = 22/103), then high blood pressure (15.5%; n = 16/103) and swelling (11.7%; n = 12/103). With respect to patient experiences, 55.2% (n = 32/58) said they did not feel sufficient information about CKD was provided at diagnosis and 59.2% (n = 45/76) said no information about their CKD stage was shared. Participants felt overwhelmed and confused about the diagnostic process and struggled to understand the information provided to them, including information about kidney function and symptoms. To supplement their understanding, participants reported using additional sources of information, including the internet (52.9%; n = 36/68), other healthcare professionals (HCPs) (19.1%; n = 13/68), books/printed information (11.8%; n = 8/68) and patient support groups (8.8%; n = 6/68). The most common emotions experienced at the time of diagnosis were worry and fear (28.2%; n = 29/103), then shock/surprise (25.2%; n = 26/103) (Figure). For those reporting no reaction (27.2%; n = 28/103), many stated the condition had no discernible effect on their daily lives. Reasons for fear or worry were related to the potential for disease progression. Conclusion Many patients expressed dissatisfaction with the information they received at their CKD diagnosis. This suggests that HCPs could dedicate more time to explaining the diagnosis, the characteristics and severity of CKD, likelihood of progression, and the benefits of self-management and adherence to intervention. This could be particularly important for those without symptoms at the time of diagnosis, and patients who rely on HCPs as their primary source of information. Patients should be asked what information they want to receive and be directed to trusted sources. The diagnostic process was a highly emotional experience for many patients and counselling or psychological therapy should be considered.

A joinpoint analysis examining trends in firearm injuries at six us trauma centers from 2016 to 2022

BackgroundThere is an epidemic of firearm injuries in the United States since the mid-2000s. Thus, we sought to examine whether hospitalization from firearm injuries have increased over time, and to examine temporal changes in patient demographics, firearm injury intent, and injury severity.MethodsThis was a multicenter, retrospective, observational cohort study of patients hospitalized with a traumatic injury to six US level I trauma centers between 1/1/2016 and 6/30/2022. ICD-10-CM cause codes were used to identify and describe firearm injuries. Temporal trends were compared for demographics (age, sex, race, insured status), intent (assault, unintentional, self-harm, legal intervention, and undetermined), and severity (death, ICU admission, severe injury (injury severity score ≥ 16), receipt of blood transfusion, mechanical ventilation, and hospital and ICU LOS (days). Temporal trends were examined over 13 six-month intervals (H1, January–June; H2, July–December) using joinpoint regression and reported as semi-annual percent change (SPC); significance was p < 0.05.ResultsFirearm injuries accounted for 2.6% (1908 of 72,474) of trauma hospitalizations. The rate of firearm injuries initially declined from 2016-H1 to 2018-H2 (SPC = − 4.0%, p = 0.002), followed by increased rates from 2018-H2 to 2020-H1 (SPC = 9.0%, p = 0.005), before stabilizing from 2020-H1 to 2022-H1 (0.5%, p = 0.73). NH black patients had the greatest hospitalization rate from firearm injuries (14.0%) and were the only group to demonstrate a temporal increase (SPC = 6.3%, p < 0.001). The proportion of uninsured patients increased (SPC = 2.3%, p = 0.02) but there were no temporal changes by age or sex. ICU admission rates declined (SPC = − 2.2%, p < 0.001), but ICU LOS increased (SPC = 2.8%, p = 0.04). There were no significant changes over time in rates of death (SPC = 0.3%), severe injury (SPC = 1.6%), blood transfusion (SPC = 0.6%), and mechanical ventilation (SPC = 0.6%). When examined by intent, self-harm injuries declined over time (SPC = − 4.1%, p < 0.001), assaults declined through 2019-H2 (SPC = − 5.6%, p = 0.01) before increasing through 2022-H1 (SPC = 6.5%, p = 0.01), while undetermined injuries increased through 2019-H1 (SPC = 24.1%, p = 0.01) then stabilized (SPC = − 4.5%, p = 0.39); there were no temporal changes in unintentional injuries or legal intervention.ConclusionsHospitalizations from firearm injuries are increasing following a period of declines, driven by increases among NH Black patients. Trauma systems need to consider these changing trends to best address the needs of the injured population.

A Single-Buyer Model of Imbalance Cost Pass-Through Pricing Forecasting in the Malaysian Electricity Supply Industry

The imbalance cost pass-through (ICPT) is a flexible component of the incentive-based regulation (IBR) that empowers power producers to adjust tariffs in response to variable fuel prices, thereby enhancing the economic resilience of electricity generation. In Malaysia, the Energy Commission has conducted biannual reviews of fuel and other generation costs. Any cost savings or increases identified during these reviews will be passed on to customers in the form of rebates or surcharges. Meanwhile, if an increment in the ICPT price signal can be provided to electricity providers and consumers, early preparation for operation budgeting can be realised, and energy management program development can be properly prepared. Due to this reason, this study proposes ICPT price forecasting for the electricity market in Peninsular Malaysia that will benefit the stakeholders. The study aims to construct an ICPT-related baseline model for the peninsular generation data by employing three forecasting methods. The forecasting performance is analysed using the mean absolute percentage error (MAPE). In light of our findings, the ARIMA method is one of the most accurate forecasting methods for fuel prices compared to the moving average (MA) and LSSVM methods. The observed price differences between the ARIMA and LSSVM models for ICPT are minimal. The ICPT price for July–December 2022 and January–June 2023 is MYR 0.21/kWh for the ARIMA and MYR 0.18/kWh for LSSVM, which are close to the actual TNB’s ICPT tariff. As for forecasting, the ICPT price is expected to drop in the next announcement. The findings of this study may have a positive impact on the sustainability of the energy sector in Malaysia.

Analysis of chlorhexidine, antibiotics and bacterial community composition in water environments from Brazil, Cameroon and Madagascar during the COVID-19 pandemic

The widespread of chlorhexidine and antibiotics in the water bodies, which grew during the global COVID-19 pandemic, can increase the dispersion of antibiotic resistance. We assessed the occurrence of these pharmaceutical compounds as well as SARS-CoV-2 and analysed the bacterial community structure of hospital and urban wastewaters from Brazil, Cameroon, and Madagascar. Water and wastewater samples (n = 59) were collected between January–June 2022. Chlorhexidine, azithromycin, levofloxacin, ceftriaxone, gentamicin and meropenem were screened by Ultra-High-Performance Liquid Chromatography coupled with mass spectrometer. SARS-CoV-2 was detected based on the nucleocapsid gene (in Cameroon and Madagascar), and envelope and spike protein-encoding genes (in Brazil). The total community-DNA was extracted and used for bacterial community analysis based on the 16S rRNA gene. To unravel likely interaction between pharmaceutical compounds and/or SARS-CoV-2 with the water bacterial community, multivariate statistics were performed. Chlorhexidine was found in hospital wastewater effluent from Brazil with a maximum concentration value of 89.28 μg/L. Additionally, antibiotic residues such as azithromycin and levofloxacin were also present at concentrations between 0.32–7.37 μg/L and 0.11–118.91 μg/L, respectively. In Cameroon, azithromycin was the most found antibiotic present at concentrations from 1.14 to 1.21 μg/L. In Madagascar instead, ceftriaxone (0.68–11.53 μg/L) and levofloxacin (0.15–0.30 μg/L) were commonly found. The bacterial phyla statistically significant different (P < 0,05) among participating countries were Proteobacteria, Patescibacteria and Dependentiae which were mainly abundant in waters sampled in Africa and, other phyla such as Firmicutes, Campylobacterota and Fusobacteriota were more abundant in Brazil. The phylum Caldisericota was only found in raw hospital wastewater samples from Madagascar. The canonical correspondence analysis results suggest significant correlation of azithromycin, meropenem and levofloxacin with bacteria families such as Enterococcaceae, Flavobacteriaceae, Deinococcaceae, Thermacetogeniaceae and Desulfomonilaceae, Spirochaetaceae, Methanosaetaceae, Synergistaceae, respectively. Water samples were also positive for SARS-CoV-2 with the lowest number of hospitalized COVID-19 patients in Madagascar (n = 7) and Brazil (n = 30). Our work provides new data about the bacterial community profile and the presence of pharmaceutical compounds in the hospital effluents from Brazil, Cameroon, and Madagascar, whose limited information is available. These compounds can exacerbate the spreading of antibiotic resistance and therefore pose a risk to public health.

“Being the main character but not always involved in one’s own care transition” - a qualitative descriptive study of older adults’ experiences of being discharged from in-patient care to home

BackgroundThe growing number of older adults with chronic diseases challenges already strained healthcare systems. Fragmented systems make transitions between healthcare settings demanding, posing risks during transitions from in-patient care to home. Despite efforts to make healthcare person-centered during care transitions, previous research indicates that these ambitions are not yet achieved. Therefore, there is a need to examine whether recent initiatives have positively influenced older adults’ experiences of transitions from in-patient care to home. This study aimed to describe older adults’ experiences of being discharged from in-patient care to home.MethodsThis study had a qualitative descriptive design. Individual interviews were conducted in January–June 2022 with 17 older Swedish adults with chronic diseases and needing coordinated care transitions from in-patient care to home. Data were analyzed using inductive qualitative content analysis.ResultsThe findings indicate that despite being the supposed main character, the older adult is not always involved in the planning and decision-making of their own care transition, often having poor insight and involvement in, and impact on, these aspects. This leads to an experience of mismatch between actual needs and the expectations of planned support after discharge.ConclusionsThe study reveals a notable disparity between the assumed central role of older adults in care transitions and their insight and involvement in planning and decision-making.

Latent tuberculosis infection care cascade among the household contacts of pulmonary tuberculosis patients – Findings from an urban feasibility study

IntroductionLatent Tuberculosis infection (LTBI) care cascade involves identification of high-risk individuals, testing, identification of LTBI, initiation of Tuberculosis Preventive therapy (TPT) and documentation of outcomes. There is a dearth of such evidence in Indian setting which needs to be further explored. Hence, this feasibility study with public private engagement was conducted with the primary objective of estimating the prevalence of LTBI among household contacts (HHCs) of pulmonary tuberculosis patients using Interferon gamma release assay (IGRA). Secondary objective was to determine the treatment outcomes among the patients of LTBI initiated on TPT. MethodsThis longitudinal community-based study was conducted in wards 47–51 at urban field practice area of our Tertiary Teaching Institute at Bhopal, Madhya Pradesh. The household contacts of pulmonary tuberculosis patients diagnosed from January–June 2022 and those who satisfied the study criteria were recruited. Those who gave consent for IGRA testing and TPT initiation were followed up for a period of 6 months to assess the treatment outcomes. Data was analyzed using R software. ResultsOf the 64 HHCs screened, 29 were the contacts of microbiologically positive and 35 were the contacts of clinically diagnosed index Tb patients including 4 under five children. Prevalence of LTBI using IGRA was 74.5%. The Contact Investigation Coverage in the urban setting was 77.1% with TPT completion of 72.4% and TPT Coverage of 55.7%. The median time for screening the HHCs since the diagnosis of index case was 14 days while screening to diagnosis was 2.5 days and that of TPT initiation from diagnosis was 22 days. ConclusionMore than half of those who were tested using IGRA were positive for LTBI. Th public private coordination helped in narrowing the time interval from diagnosis of index tb case to contact tracing and improving the TPT adherence among the HHCs. However, intensive efforts are required to narrow the screening gap of HHCs and TPT initiation. Also, reasons for loss to follow up and missed doses needs to be qualitatively explored.
