RESUMO
Our goal was to determine the prevalence of anxiety and depression in a sample of U.S. military veterans with type 2 diabetes and elevated diabetes distress (DD). Cross-sectional analyses were conducted. The association between DD and anxiety and depression was assessed with logistic regression. Almost 80% of persons with elevated DD had clinically significant anxiety or depression symptoms. The odds of depression and anxiety increased with DD severity. Given the large overlap of depression and anxiety with elevated DD, we recommend providers screen for all three conditions and, if positive, connect to resources for diabetes self-management and/or clinical treatment.
RESUMO
As lead molecules, cyclic lipopeptides with antibacterial, antifungal, and antiviral properties have garnered a lot of attention in recent years. Because of their potential, cyclic lipopeptides have earned recognition as a significant class of antimicrobial compounds with applications in pharmacology and biotechnology. These lipopeptides, often with biosurfactant properties, are amphiphilic, consisting of a hydrophilic moiety, like a carboxyl group, peptide backbone, or carbohydrates, and a hydrophobic moiety, mostly a fatty acid. Besides, several lipopeptides also have cationic groups that play an important role in biological activities. Antimicrobial lipopeptides can be considered as possible substitutes for antibiotics that are conventional to address the current drug-resistant issues as pharmaceutical industries modify the parent antibiotic molecules to render them more effective against antibiotic-resistant bacteria and fungi, leading to the development of more resistant microbial strains. Bacillus species produce lipopeptides, which are secondary metabolites that are amphiphilic and are typically synthesized by non-ribosomal peptide synthetases (NRPSs). They have been identified as potential biocontrol agents as they exhibit a broad spectrum of antimicrobial activity. A further benefit of lipopeptides is that they can be produced and purified biotechnologically or biochemically in a sustainable manner using readily available, affordable, renewable sources without harming the environment. In this review, we discuss the biochemical and functional characterization of antifungal lipopeptides, as well as their various modes of action, method of production and purification (in brief), and potential applications as novel antibiotic agents.

We describe an epidemiologic investigation and successful control measures for the first reported outbreak of blaNDM-1-carrying Pseudomonas aeruginosa in Texas occurring in a veteran with transmission of the same organism and a blaNDM-5-carrying Escherichia coli, respectively, to two roommates and blaNDM-carrying organism/s to a patient cared for by common staff.
RESUMO
Introduction: LNG-IUD although used extensively for its non-contraceptive indications like abnormal uterine bleeding (AUB), dysmenorrhoea and fibroid uterus, one of the major drawbacks is the high expulsion rates, especially among adenomyotic and fibroid uterus. Material and Methods: Altius Hospitals, Bangalore have developed a new technique of LNG-IUD fixation, which employs hystero-laparoscopy and usage of a long port closure needle with delayed absorbable sutures. Conclusion: It ensures proper placement and fixation of the LNG-IUD to the uterine cavity, reduces the expulsion rates and has the advantages of being a day care procedure. Supplementary Information: The online version contains supplementary material available at 10.1007/s13224-023-01788-2.
RESUMO
OBJECTIVE: The primary objective of this research was to assess the impact of a novel, peer-directed intervention (iNSPiRED) on diabetes distress (DD) among veterans with type 2 diabetes and DD. Secondary objectives were to assess iNSPiRED's impact on anxiety, depression, and diabetes self-management behaviors. METHOD: A single-blinded, randomized, parallel-group trial was conducted. Participants (n = 218) were recruited through a Veterans Affairs medical center and community agencies in a major metropolitan area from September 2019 through January 2022. Certified mental health peer specialists delivered iNSPiRED, a three-month goal-setting and resource navigation intervention. Outcomes were assessed at baseline, postintervention, and month six. Multilevel random-intercept linear regression models with treatment x time interaction terms were used to assess treatment effects. RESULTS: Frequency of following a healthy eating plan was higher for iNSPiRED vs usual care at month three relative to baseline (B = 0.58; p = 0.03) after adjusting for race and socioeconomic status. No other treatment effects differed significantly from zero (ps ≥ 0.05). CONCLUSION: Peer-directed interventions have the potential to deliver low-cost, highly scalable care. However, based on the largely negative findings of the current study, it is likely that more intense, multimodal interventions are needed to address DD.

Background: Low cardiac output is a common complication following cardiac surgery and it is associated with higher mortality in the pediatric population. A gold standard method for cardiac output (CO) monitoring in the pediatric population is lacking. The present study was conducted to validate cardiac output and cardiac index measured by transthoracic echocardiography and Pressure recording analytical method, a continuous pulse contour method, MostCareUp in postoperative pediatric cardiac surgical patients. Materials and Methods: This was a prospective observational clinical study conducted at a tertiary care hospital. A total of 23 pediatric patients weighed between 2 and 20 kg who had undergone elective cardiac surgery were included in the study. Results: Spearman's correlation coefficient of CO between transthoracic echocardiography (TTE) and Pressure Recording Analytical Method (PRAM) showed of positive correlation (r = 0.69, 95% Confidence interval 0.59-0.77, P < 0.0001) Linear regression equations for CO between TTE and PRAM were y = 0.55 + 0.88x (R2 = 0.46, P < 0.0001). (y = PRAM, x = TTE), respectively. Bland- Altman plot for CO between TTE and PRAM showed a bias of -0.397 with limits of the agreement being -2.01 to 1.22. Polar plot analysis showed an angular bias of 6.55° with radial limits of the agreement being -21.46 to 34.58 for CO and angular bias of 6.22° with radial limits of the agreement being -22.4 to 34.84 for CI. Conclusion: PRAM has shown good trending ability for cardiac output. However, values measured by PRAM are not interchangeable with the values measured by transthoracic echocardiography.

OBJECTIVE: Continuous glucose monitoring (CGM) parameters may identify individuals at risk for progression to overt type 1 diabetes. We aimed to determine whether CGM metrics provide additional insights into progression to clinical stage 3 type 1 diabetes. RESEARCH DESIGN AND METHODS: One hundred five relatives of individuals in type 1 diabetes probands (median age 16.8 years; 89% non-Hispanic White; 43.8% female) from the TrialNet Pathway to Prevention study underwent 7-day CGM assessments and oral glucose tolerance tests (OGTTs) at 6-month intervals. The baseline data are reported here. Three groups were evaluated: individuals with 1) stage 2 type 1 diabetes (n = 42) with two or more diabetes-related autoantibodies and abnormal OGTT; 2) stage 1 type 1 diabetes (n = 53) with two or more diabetes-related autoantibodies and normal OGTT; and 3) negative test for all diabetes-related autoantibodies and normal OGTT (n = 10). RESULTS: Multiple CGM metrics were associated with progression to stage 3 type 1 diabetes. Specifically, spending ≥5% time with glucose levels ≥140 mg/dL (P = 0.01), ≥8% time with glucose levels ≥140 mg/dL (P = 0.02), ≥5% time with glucose levels ≥160 mg/dL (P = 0.0001), and ≥8% time with glucose levels ≥160 mg/dL (P = 0.02) were all associated with progression to stage 3 disease. Stage 2 participants and those who progressed to stage 3 also exhibited higher mean daytime glucose values; spent more time with glucose values over 120, 140, and 160 mg/dL; and had greater variability. CONCLUSIONS: CGM could aid in the identification of individuals, including those with a normal OGTT, who are likely to rapidly progress to stage 3 type 1 diabetes.

Limited data is available to assess the burden of maternal morbidity, mortality, and perinatal outcome after subsequent pregnancy in women with prior uterine rupture. Therefore, this retrospective descriptive study was conducted to determine subsequent pregnancy outcomes in a larger series of women with prior complete uterine rupture. All pregnant women who had complete uterine rupture were managed according to the standard Institute protocol. The women who conceived following a uterine repair from July 2011 to June 2020 were recruited into the study. Outcome measures included severe maternal morbidities and perinatal outcomes. Fifty-three women with prior complete uterine rupture were conceived subsequently. Two women had an abortion in the first and second trimester, respectively. None of the women developed recurrence of uterine rupture. However, three women developed uterine dehiscence in a total of 16 women who went into spontaneous labour before elective cesarean delivery at 32, 36, and 37 weeks, respectively. None of the women had placenta previa, placenta accreta, bowel injury, bladder injury and none required a hysterectomy. However, 16.7% of women needed a blood transfusion. None of the women required mechanical ventilation, inotropic support, and intensive care unit stay. Seventeen babies required neonatal intensive care admission, and prematurity (90%) was the most common reason, followed by low APGAR scores. In conclusion, subsequent pregnancy outcomes in women with prior uterine rupture appear acceptable in institutionalized care. Timing of cesarean delivery may have to be weighed against the risk of prematurity-associated neonatal morbidity and mortality.

Ultrasound-assisted approach has been investigated for delignification so as to develop green and sustainable technology. Combination of NaOH with ultrasound has been applied with detailed study into effect of various parameters such as time (operating range of 15-90 min), alkali concentration (0.25 M-2.5 M), solvent loading (1:15-1:30 w/v), temperature (50-90 ËC), power (40-140 W) and duty cycle (40-70 %) at fixed frequency of 20 kHz. The optimized operating conditions established for the ultrasonic horn were 1 M as the NaOH concentration, 1 h as treatment time, 70ËC as the operating temperature, 1:20 as the biomass loading ratio, 100 W as the ultrasonic power and 70% duty cycle yielding 67.30% as the delignification extent. Comparative study performed using conventional and ultrasonic bath assisted alkaline treatment revealed lower delignification as 48.09% and 61.55% respectively. The biomass samples were characterized by SEM, XRD, FTIR and BET techniques to establish the role of ultrasound during the treatment. The morphological changes based on the ultrasound treatment demonstrated by SEM were favorable for enhanced delignification and also the crystallinity index was more in the case of ultrasound treated material than that obtained by conventional method. Specific surface area and pore size determinations based on BET analysis also confirmed beneficial role of ultrasound. The overall results clearly demonstrated the intensification obtained due to the use of ultrasonic reactors.

INTRODUCTION: Endometrial injury (ES) has been suggested as intervention to increase probability of pregnancy in women undergoing assisted reproductive technologies. Majority of studies reported that ES improves outcome in Invitro fertilisation,Intrauterine Insemination(IUI) and natural conceptions: however, the size and quality of studies are poor which questions the presence of any beneficial effect. The present study was done to evaluate the effect of endometrial scratching on pregnancy rate after previous failed Intrauterine Insemination and to assess the pain and bleeding following the procedure. MATERIAL AND METHODS: Randomized controlled trial. One hundred sixty-eight women (Eighty-four in each group) with primary/secondary infertility were recruited and randomized into intervention and control group using block randomization. Intervention group underwent ES using pipelle's canula on D8 or D9 of menstrual cycle. Three cycles of ovulation induction with Clomiphene citrate and gonadotrophins followed by IUI was done. The primary end point was clinical pregnancy rate. Pain and bleeding after the procedure were evaluated as secondary outcomes.The study was conducted from June 2017 to June 2019. MAIN RESULTS: The cumulative clinical pregnancy rate in ES group was 22.2 % in comparison 9.8 % in control group. In the intent to treat analysis, with a p value of 0.03 calculated from Chi-square test(p < 0.05) there was statistically significant difference in the pregnancy rate between Intervention and Control group. Efficacy of intervention was found to be Fourteen Percent (14 %). Fifty-one women (63 %) had marked a VAS pain score of 4-5 and Twelve women(12.2 %) experienced mild spotting post procedure. Two patients in ES group had miscarriage and no case of multiple pregnancy in both the groups. CONCLUSION: Endometrial Scratching improves clinical pregnancy rate in patients with Unexplained infertility and mild male factor infertility with previous failed IUI cycles. ES will be an inexpensive alternative to IVF for couples after IUI failures especially in developing countries, with an acceptable pregnancy rate and does not demand any special qualification or equipment and can be trained easily in primary settings. Larger and adequately powered studies are needed to elucidate the beneficial effects of endometrial scratching on implantation.

PURPOSE OF REVIEW: There likely are several predisposing factors to secondary infections in patients with Coronavirus disease 2019 (COVID-19), some of which may be preventable. The aim of this review is to explore the literature, summarize potential predisposing factors to secondary infections and their incidence. It also summarizes a variety of healthcare scenarios in which different kinds of secondary infections occur. RECENT FINDINGS: Apart from immune dysregulation, severe resource limitations in healthcare settings have made COVID-19 units conducive to a variety of secondary infections. Long-term effect of excess antibiotic use in COVID-19 patients is yet to be studied. Very few studies have assessed secondary infections as the primary outcome measure making it difficult to know the true incidence. Mortality attributable to secondary infections in COVID-19 patients is also unclear. SUMMARY: Incidence of secondary infections in COVID-19 patients is likely higher than what is reported in the literature. Well designed studies are needed to understand the incidence and impact of secondary infections in this patient population. Many of these may be preventable especially now, as personal protective equipment and other healthcare resources are recovering. Infection prevention and control (IPC) and antimicrobial stewardship programmes (ASP) must reassess current situation to correct any breaches that could potentially cause more harm in these already vulnerable patients as we brace for a future surge with another pandemic wave.

Probiotics have gained a lot of interest in recent years as an alternative as well as adjuvant therapy for several conditions owing to their health benefits. These live microorganisms have proven efficacy for treating gut disorders, inflammation, bacterial vaginosis, hepatic and depressive disorders, and many more. There are conventional as well as non-conventional formulations available for the delivery of probiotics with the latter having fewer regulatory guidelines. The conventional formulations include the pharmaceutical formulations specifically designed to deliver an efficacious number of viable microorganisms. Studies have indicated 108-109 CFU/g as an ideal dose of probiotics for achieving health benefits, and hence, all the formulations must at least contain the said number of viable bacteria to show a therapeutic effect. The most crucial feature of probiotic formulations is that the bacteria are prone to several environmental and processing factors which all together reduce the viability of the bacteria in the final formulation. These factors include processing parameters like temperature, humidity, pressure, and storage conditions. Thus, the present review primarily focuses on the critical process parameters affecting the probiotic viability during stabilization process and formulation development. Understanding these factors prior to processing helps in delivering probiotics in the required therapeutic numbers at the target site.

BACKGROUND: When traditional interventions are used in long term care for catheter associated urinary tract infection (CAUTI) prevention, residual rates are still high despite a decrease. We conducted a quality improvement study focusing our interventions on patient and staff behavioral patterns identified through a structured huddle process to improve upon the basics for CAUTI prevention. METHODS: Baseline was from January 2016 to March 2017; the intervention period was from April 2017 to June 2020. We implemented a systematic huddle to determine root cause of each CAUTI and applied lessons throughout the facility. We measured the monthly CAUTI incidence per 1000 urinary catheter days and analyzed the reduction in CAUTI during the intervention period. RESULTS: CAUTI decreased by 73% during the intervention period compared to the baseline period, with an IRR of 0.27 (95% confidence interval [CI]: 0.11-0.66; Pâ¯=â¯.004). The number of catheter days per month increased by 4% in the intervention period (17,407 in 39 months) compared to the baseline period (6,440 in 15 months) with IRR of 1.04 (95% confidence interval [CI]: 1.01-1.07; Pâ¯=â¯.008). No patterns were noted in organisms responsible for CAUTI. CONCLUSIONS: Our findings stress the importance of looking beyond the traditional interventions for CAUTI prevention in long term care population. By doing this, interventions can be customized for this special population to achieve optimal outcomes.

Immune checkpoint inhibitor-associated diabetes mellitus (ICI-DM) is a known immune-related adverse event (irAE) following treatment with programmed cell death protein 1 (PD-1), with a reported 0.9% incidence. We hereby present the first case, to our knowledge, of ICI-DM following ICI use in a human immunodeficiency virus (HIV) patient. In this case, a 48-year-old man with HIV stable on highly active antiretroviral therapy (HAART) was diagnosed with Hodgkin lymphoma and initiated treatment with the PD-1 inhibitor nivolumab. His lymphoma achieved complete response after 5 months. However, at month 8, he reported sudden polydipsia and polyuria. Labs revealed a glucose level of 764 mg/dL and glycated hemoglobin A1c (HbA1c) of 7.1%. Low C-peptide and elevated glutamic acid decarboxylase 65 (GAD65) antibody levels confirmed autoimmune DM, and he was started on insulin. Major histocompatibility complex class II genetic analysis revealed homozygous HLA DRB1*03-DQA1*0501-DQB1*02 (DR3-DQ2), which is a known primary driver of genetic susceptibility to type 1 DM. Autoimmune DM has been reported as an ICI-associated irAE. However, patients with immunocompromising conditions such as HIV are usually excluded from ICI trials. Therefore, little is known about such irAEs in this population. In this case, risk of ICI-DM as an irAE was likely increased by several factors including family history, a high-risk genetic profile, islet-related immunologic abnormalities, active lymphoma, and HIV infection with a possible immune reconstitution event. Clinicians should maintain a high index of suspicion for development of irAEs associated with ICI, particularly as use of these therapies broadens. Thorough investigation for presence of higher-risk features should be conducted and may warrant inclusion of pre-therapy genetic and/or autoantibody screening.
RESUMO
INTRODUCTION: DGAT and MGAT enzymes play an important role in triacylglycerol (TGA) biosynthesis. Overexpression of these enzymes may lead to accumulation of TGA in adipose tissues causing development of diseases such as obesity and diabetes. High triglyceride levels increase risk factors for atherosclerosis, and increase the risk of heart attack, stroke and other heart diseases. DGAT and MGAT inhibitors are used for the treatment of such metabolic diseases. A number of DGAT and MGAT inhibitors entered into clinical and preclinical stages. However, some adverse effects are associated with them. Thus there is need to develop new, potent and safe DGAT and MGAT inhibitors. AREA COVERED: In this review, the authors carefully searched patent literature and reviewed recent advances since the year 2014. Diverse chemical classes reported in the patents belonging to the category DGAT and MGAT inhibitors have been highlighted. EXPERT OPINION: DGAT and MGAT inhibitors are now gaining significant importance in the treatment of metabolic diseases. Fused heterocycles with a combination of aromatic and aliphatic hydrophobic substituents could offer more potent DGAT and MGAT inhibitors. Previously reported chemical scaffolds and their DGAT and MGAT inhibitory activity could be employed as an input for some in silico studies to discover novel, potent and safe DGAT and MGAT inhibitors.

PURPOSE: To evaluate if size-based cut-offs based on MR imaging can successfully assess clinically significant prostate cancer (csPCA). The goal was to improve the currently applied size-based differentiation criterion in PI-RADS. METHODS AND MATERIALS: MRIs of 293 patients who had undergone 3 T MR imaging with subsequent confirmation of prostate cancer on systematic and targeted MRI/TRUS-fusion biopsy were re-read by three radiologists. All identifiable tumors were measured on T2WI for lesions originating in the transition zone (TZ) and on DWI for lesions from the peripheral zone (PZ) and tabulated against their Gleason grade. RESULTS: 309 lesions were analyzed, 213 (68.9 %) in the PZ and 96 (31.1 %) in the TZ. ROC-Analysis showed a stronger correlation between lesion size and clinically significant (defined as Gleason Grade Group ≥ 2) prostate cancer (PCa) for the PZ (AUC = 0.73) compared to the TZ (AUC = 0.63). The calculated Youden index resulted in size cut-offs of 14 mm for PZ and 21 mm for TZ tumors. CONCLUSION: Size cut-offs can be used to stratify prostate cancer with different optimal size thresholds in the peripheral zone and transition zone. There was a clearer separation of clinically significant tumors in peripheral zone cancers compared to transition zone cancers. Future iterations of PI-RADS could therefore take different size-based cut-offs for peripheral zone and transition zone cancers into account.

OBJECTIVES: To assess the discriminatory power of lexicon terms used in PI-RADS version 2 to describe MRI features of prostate lesions. METHODS: Four hundred fifty-four patients were included in this retrospective, institutional review board-approved study. Patients received multiparametric (mp) MRI and subsequent prostate biopsy including MRI/transrectal ultrasound fusion biopsy and 10-core systematic biopsy. PI-RADS lexicon terms describing lesion characteristics on mpMRI were assigned to lesions by experienced readers. Positive and negative predictive values (PPV, NPV) of each lexicon term were assessed using biopsy results as a reference standard. RESULTS: From a total of 501 lesions, clinically significant prostate cancer (csPCa) was present in 175 lesions (34.9%). Terms related to findings of restricted diffusion showed PPVs of up to 52.0%/43.9% and NPV of up to 91.8%/89.7% (peripheral zone or PZ/transition zone or TZ). T2-weighted imaging (T2W)-related terms showed a wide range of predictive values. For PZ lesions, high PPVs were found for "markedly hypointense," "lenticular," "lobulated," and "spiculated" (PPVs between 67.2 and 56.7%). For TZ lesions, high PPVs were found for "water-drop-shaped" and "erased charcoal sign" (78.6% and 61.0%). The terms "encapsulated," "organized chaos," and "linear" showed to be good predictors for benignity with distinctively low PPVs between 5.4 and 6.9%. Most T2WI-related terms showed improved predictive values for TZ lesions when combined with DWI-related findings. CONCLUSIONS: Lexicon terms with high discriminatory power were identified (e.g., "markedly hypointense," "water-drop-shaped," "organized chaos"). DWI-related terms can be useful for excluding TZ cancer. Combining T2WI- with DWI findings in TZ lesions markedly improved predictive values. KEY POINTS: ⢠Lexicon terms describing morphological and functional features of prostate lesions on MRI show a wide range of predictive values for prostate cancer. ⢠Some T2-related terms have favorable PPVs, e.g., "water-drop-shaped" and "organized chaos" while others show less distinctive predictive values. DWI-related terms have noticeable negative predictive values in TZ lesions making DWI feature a useful tool for exclusion of TZ cancer. ⢠Combining DWI- and T2-related lexicon terms for assessment of TZ lesions markedly improves PPVs. Most T2-related lexicon terms showed a significant decrease in PPV when combined with negative findings for "DW hyperintensity."

BACKGROUND: There is a paucity of data evaluating the strategy of suppressing broader-spectrum antibiotic susceptibilities on utilization. Cascade reporting (CR) is a strategy of reporting antimicrobial susceptibility test results in which secondary (eg, broader-spectrum, costlier) agents may only be reported if an organism is resistant to primary agents within a particular drug class. Our objective was to evaluate the impact of ceftriaxone-based cascade reporting on utilization of cefepime and clinical outcomes in patients with ceftriaxone-susceptible Escherichia and Klebsiella clinical cultures. METHODS: We compared post-CR (July 2014-June 2015) with baseline (July 2013-June 2014), evaluating utilization of cefepime, cefazolin, ceftriaxone, ampicillin derivatives, fluoroquinolones, piperacillin/tazobactam, ertapenem, and meropenem; new Clostridium difficile infection; and length of stay (LOS) after the positive culture, 30-day readmission, and in-hospital all-cause mortality. RESULTS: Mean days of therapy (DOT) among patients who received any antibiotic for cefepime decreased from 1.229 days during the baseline period to 0.813 days post-CR (adjusted relative risk, 0.668; Pâ <â .0001). Mean DOT of ceftriaxone increased from 0.864 days to 0.962 days, with an adjusted relative risk of 1.113 (Pâ =â .004). No significant differences were detected in other antibiotics including ertapenem and meropenem, demonstrating the direct association of the decrease in cefepime utilization with CR based on ceftriaxone susceptibility. Average LOS in the study population decreased from 14.139 days to 10.882 days from baseline to post-CR and was found to be statistically significant (Pâ <â .0001). CONCLUSIONS: In conclusion, we demonstrated significant association of decreased cefepime utilization with the implementation of a CR based on ceftriaxone susceptibility. We demonstrated the safety of deescalation, with LOS being significantly lower during the post-CR period than in the baseline period, with no change in in-hospital mortality.
