Outcomes of Patients With Sepsis and Septic Shock Requiring Source Control: A Prospective Observational Single-Center Study.

Source control is important in management of septic shock. We studied differences in outcomes of patients with sepsis and septic shock who required source control intervention compared with those who did not need such intervention and the effect of the timing of source control on various clinical outcomes. DESIGN: Prospective observational study from February 28, 2020, to March 31, 2021. SETTING: Medical ICU of academic quaternary medical center. PATIENTS: Two hundred five adult (≥18 yr) ICU patients. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Patients were divided into a medical treatment group and a source control group. Patients requiring source control were further divided into early (intervention performed < 24 hr) and late (≥ 24 hr) source control groups. The primary outcomes were 30-day and ICU mortality. Secondary outcomes were ICU and hospital length of stay (LOS), days on mechanical ventilation, and need for renal replacement therapy. A total of 45.9% patients underwent source control. Of these, early source control was performed in 44.7% and late source control in 55.3% of patients. There was no significant difference in 30-day mortality or ICU mortality in the medical versus source control groups or in early versus late source control groups. Compared with the medical group, mean hospital LOS (11.5 vs 17.4 d; p < 0.01) and ICU LOS (5.2 vs 7.7 d; p < 0.01) were longer in the source control group. The hospital LOS (12.5 vs 21.4 d; p < 0.01) and ICU LOS (5.2 vs 9.7 d; p < 0.01) were also longer in patients who had delayed source control than in patients who had early source control. There were no significant differences in other outcomes. CONCLUSIONS: Although mortality was similar, patients who had delayed source control had a longer ICU and hospital LOS. Early source control may improve health care utilization in septic shock patients.

An Audit of the effect of Bone Morphogenetic Protein-2 Treatment in patients with non-union of long bone fractures.

OBJECTIVE: To evaluate the outcomes, clinical and radiological application of Bone Morphogenetic Protein-2 alone versus Bone Morphogenetic Protein-2 with autograft in long bone non-unions. METHODS: A prospective review of patients was done with fracture non-union admitted to Aga Khan University Hospital, Karachi, from January 2016 to January 2019. The patients were divided into two groups; those exposed to Bone Morphogenetic Protein-2 alone in group 1, and those exposed to Bone Morphogenetic Protein-2 plus autologous graft in group 2. RESULTS: Background characteristics of both the groups were analysed. Patients were followed up at 6, 12 and 24 weeks through their medical records. The primary outcome was postoperative union at 6, 12 and 24. Union was defined by having the clinical union as well as the radiological union at the same time of assessment. Of the 80 patients enrolled, 13(16.25%) were excluded, and 5(6.25%) were lost to follow-up. The final sample had 62(77.5%) patients; 35(56.5%) in group 1, and 27(43.5%) in group 2. Union at 6 weeks was observed in 13(21%) patients; 8(62%) in group 1, and 5(38%) in group 2. Union at 12 weeks was observed in 38(61%) patients; 20(53%) in group 1, and 18(47%) in group 2. CONCLUSIONS: Results showed that using the adjuvant treatment alone was not worse than using it along with bone autologous graft.

Interventions for Neglected Tropical Diseases Among Children and Adolescents: A Meta-analysis.

BACKGROUND: Neglected tropical diseases (NTDs) are a group of communicable diseases affecting the poorest populations around the world. OBJECTIVE: To assess the effectiveness of interventions, including mass drug administration (MDA), water, sanitation, and hygiene (WASH), vector control, health education, and micronutrients supplementation, for NTDs among children and adolescents. METHODS: We conducted a literature search on the Cochrane Controlled Trials Register, Medline, and other databases until December 2020. We included randomized controlled trials and quasi-experimental studies conducted among children and adolescents. Two authors independently screened studies for relevance. Two authors independently extracted data, assessed the risk of bias, performed metaanalysis, and rated the quality of evidence using the Grading of Recommendations, Assessment, Development, and Evaluation. RESULTS: We included 155 studies (231 articles) involving 262 299 participants. For soil-transmitted helminthiasis, MDA may reduce the prevalence of Ascaris, Trichuris, and hookworm by 58%, 36%, and 57%, respectively. We are uncertain of the effect of health education, WASH, and iron supplementation on soil-transmitted helminthiasis prevalence. For Schistosomiasis, health education probably reduces the intensity and prevalence of S. mansoni, whereas micronutrient supplementation may reduce anemia prevalence and the infection intensity of S. hematobium compared with no supplementation. We are uncertain of the effect of MDA and vector control on Schistosomiasis outcomes. For trachoma, health education probably reduces the prevalence of active Trachoma, whereas we are uncertain of the effect of MDA, WASH, and vector control on Trachoma outcomes. There is limited data on the effectiveness of interventions for NTDs targeting children and adolescents. CONCLUSION: Future studies are needed to evaluate the relative effectiveness and cost-effectiveness of various interventions specifically targeting children and adolescents.

A Review: Molecular Chaperone-mediated Folding, Unfolding and Disaggregation of Expressed Recombinant Proteins.

The advancements in biotechnology over time have led to an increase in the demand of pure, soluble and functionally active proteins. Recombinant protein production has thus been employed to obtain high expression of purified proteins in bulk. E. coli is considered as the most desirable host for recombinant protein production due to its inexpensive and fast cultivation, simple nutritional requirements and known genetics. Despite all these benefits, recombinant protein production often comes with drawbacks, such as, the most common being the formation of inclusion bodies due to improper protein folding. Consequently, this can lead to the loss of the structure-function relationship of a protein. Apart from various strategies, one major strategy to resolve this issue is the use of molecular chaperones that act as folding modulators for proteins. Molecular chaperones assist newly synthesized, aggregated or misfolded proteins to fold into their native conformations. Chaperones have been widely used to improve the expression of various proteins which are otherwise difficult to produce in E. coli. Here, we discuss the structure, function, and role of major E. coli molecular chaperones in recombinant technology such as trigger factor, GroEL, DnaK and ClpB.

Identifying and Bridging the Gaps in Antimicrobial Stewardship in Post-Acute and Long-Term Care.

National organizations have developed guidelines and tools for antimicrobial stewardship (AMS) in post-acute and long-term care (PALTC), but there is a need to effectively translate these into actionable, measurable, and impactful programs. An electronic needs assessment survey was developed and distributed to health care providers and administrators involved with AMS activities in PALTC facilities in Maryland. The results of this survey were used to develop a statewide initiative to improve AMS in nursing facilities. The survey revealed that barriers to implementing AMS include limited access or poor utilization of experts in AMS and infectious disease, adverse event data collection tools, and locally developed protocols and guidelines. Strategies to improve AMS included the provision of free continuing education to a multidisciplinary audience and improved access to individuals with expertise in infectious disease and the development of an adverse drug event tool. Continuing to provide meaningful tools and resources that address the specific needs of nursing facilities should lead to improved compliance with regulations and ultimately improved resident outcomes.

Recommendations for Mandatory Influenza Vaccinations for Health Care Personnel From AMDA's Infection Advisory Subcommittee.

Preventing influenza infections is a national health priority, particularly among geriatric and adults with frailty who reside in post-acute and long-term care (PALTC) settings. Older adults account for more than 70% of deaths from influenza, a reflection of decreased vaccine effectiveness in that age group. Annually vaccinating health care personnel (HCP) working with these patients against influenza is critical to reducing influenza morbidity and mortality among patients. PALTC HCP have the lowest influenza vaccination rate when compared to HCP in other settings. The Advisory Committee on Immunization Practices recommends that all HCP receive an annual influenza vaccination, including those who do not have direct patient care responsibilities. Here, we discuss the importance of influenza vaccination for HCP, detail recommendations for influenza vaccination practice and procedures for PALTC settings, and offer support to PALTC settings and their staff on influenza vaccinations.

Appraising a guideline for preventing acute care falls.

Although falling may seem like a simple event, in reality it is a complex medical issue leading to serious injuries including fractures, lacerations, soft tissue and traumatic brain injuries, and even death. The Nurses Improving Care for Health System Elders (NICHE) guideline for falls prevention in acute care unit was formulated by incorporating recommendations from systematic reviews of the literature and advice from expert consensus. Recommendations include pre-fall risk assessment, utilization of a post-fall assessment tool, follow-up monitoring for 48 hours, and implementation of an individualized, multidisciplinary plan of care to address treatable problems that contributed to the fall and to prevent future falls. The guideline also calls for staff education.

Evidence-based review of interventions to improve palliation of pain, dyspnea, depression.

This review of the guideline developed by the Clinical Efficacy Subcommittee of the American College of Physicians and the accompanying systematic review offers clinicians evidence-based recommendations for palliative care. Seriously ill patients should be assessed for pain, dyspnea, and depression. Clinicians should use therapies of proven effectiveness to manage pain, depression, and dyspnea, including opioids in patients with unrelieved dyspnea and oxygen for short-term relief of hypoxemia. Clinicians should ensure that advance care planning, including completion of advance directives, occurs.
