2003· New England Journal of Medicine914doi:10.1056/nejmoa035026

BACKGROUND: The T-20 vs. Optimized Regimen Only Study 1 (TORO 1) was a randomized, open-label, phase 3 study of enfuvirtide (T-20), a human immunodeficiency virus type 1 (HIV-1) fusion inhibitor. METHODS: Patients from 48 sites in the United States, Canada, Mexico, and Brazil with at least six months of previous treatment with agents in three classes of antiretroviral drugs, resistance to drugs in these classes, or both, and with at least 5000 copies of HIV-1 RNA per milliliter of plasma were randomly assigned in a 2:1 ratio to receive enfuvirtide plus an optimized background regimen of three to five antiretroviral drugs or such a regimen alone (control group). The primary efficacy end point was the change in the plasma HIV-1 RNA level from base line to week 24. RESULTS: A total of 501 patients underwent randomization, and 491 received at least one dose of study drug and had at least one measurement of plasma HIV-1 RNA after treatment began. The two groups were balanced in terms of the median base-line HIV-1 RNA level (5.2 log10 copies per milliliter in both groups), median CD4+ cell count (75.5 cells per cubic millimeter in the enfuvirtide group, and 87.0 cells per cubic millimeter in the control group), demographic characteristics, and previous antiretroviral therapy. At 24 weeks, the least-squares mean change from base line in the viral load (intention-to-treat, last observation carried forward) was a decrease of 1.696 log10 copies per milliliter in the enfuvirtide group, and a decrease of 0.764 log10 copies per milliliter in the control group (P<0.001). The mean increases in CD4+ cell count were 76 cells per cubic millimeter and 32 cells per cubic millimeter, respectively (P<0.001). Reactions at the site of the injections were reported by 98 percent of patients receiving enfuvirtide. There were more cases of pneumonia in the enfuvirtide group than in the control group. CONCLUSIONS: The addition of enfuvirtide to an optimized antiretroviral regimen provided significant antiretroviral and immunologic benefit through 24 weeks in patients who had previously received multiple antiretroviral drugs and had multidrug-resistant HIV-1 infection.

2008· New England Journal of Medicine360doi:10.1056/nejmoa0803154

BACKGROUND: We conducted subanalyses of the combined results of the Maraviroc versus Optimized Therapy in Viremic Antiretroviral Treatment-Experienced Patients (MOTIVATE) 1 and MOTIVATE 2 studies to better characterize the efficacy and safety of maraviroc in key subgroups of patients. METHODS: We analyzed pooled data from week 48 from the two studies according to sex, race or ethnic group, clade, CC chemokine receptor 5 (CCR5) delta32 genotype, viral load at the time of screening, the use or nonuse of enfuvirtide in optimized background therapy (OBT), the baseline CD4 cell count, the number of active antiretroviral drugs coadministered, the first use of selected background agents, and tropism at baseline. Changes in viral tropism and the CD4 count at treatment failure were evaluated. Data on aminotransferase levels in patients coinfected with hepatitis B virus (HBV) or hepatitis C virus (HCV) were also analyzed. RESULTS: A treatment benefit of maraviroc plus OBT over placebo plus OBT was shown in all subgroups, including patients with a low CD4 cell count at baseline, those with a high viral load at screening, and those who had not received active agents in OBT. Analyses of the virologic response according to the first use of selected background drugs showed the additional benefit of adding a potent new drug to maraviroc at the initiation of maraviroc therapy. More patients in whom maraviroc failed had a virus binding to the CXC chemokine receptor 4 (CXCR4) at failure, but there was no evidence of a decrease in the CD4 cell count at failure in such patients as compared with those in whom placebo failed. Subanalyses involving patients coinfected with HBV or HCV revealed no evidence of excess hepatotoxic effects as compared with baseline. CONCLUSIONS: Subanalyses of pooled data from week 48 indicate that maraviroc provides a valuable treatment option for a wide spectrum of patients with R5 HIV-1 infection who have been treated previously.

2009· The Journal of Infectious Diseases192doi:10.1086/597207

BACKGROUND: Human immunodeficiency virus (HIV)-seropositive men who have sex with men (MSM) are at higher risk of human papillomavirus (HPV) infection. This study was conducted to better understand the natural history of type-specific HPV infection in the anus. METHODS: A cohort study was conducted among HIV-seropositive MSM in Montreal to investigate acquisition and loss of anal HPV infection. Participants were followed up every 6 months for 3 years for risk behaviors, HIV-related parameters, and HPV testing. RESULTS: HPV DNA was detected in 97.9% of the 247 participants at baseline (median, 5 HPV types). The most common types were HPV-16 (38.2%) and HPV-6 (35.3%). Prevalent HPV-16 infections had the lowest clearance rate (12.2 cleared episodes per 1000 person-months [95% confidence interval {CI}, 8.5-17.7]) and a mean retention time of 36 months (95% CI, 32.7-38.8). The highest incidence rates were found for HPV-16 (10.8 new cases per 1000 person-months [95% CI, 8.0-14.7]), HPV-52 (10.8 new cases per 1000 person-months [95% CI, 8.2-14.1]), and HPV-53 (9.8 new cases per 1000 person-months [95% CI, 7.4-13.0]), with cumulative incidences at 36 months of approximately 30%. CONCLUSIONS: Multiple HPV types were common in the anal canals of HIV-seropositive MSM. Incidence and clearance rates were not similar among HPV types. Ongoing surveillance of this cohort will help our understanding of the determinants of HPV persistence and progression to lesions.

OBJECTIVE: Use of preexposure prophylaxis (PrEP) for HIV raises concerns about sexually transmitted infection (STI) incidence because of decreased condom use among MSM. This study examines whether PrEP is associated with STIs in the 12 months following PrEP prescription relative to the 12 months prior to PrEP and if STI rates are higher among PrEP users relative to individuals receiving postexposure prophylaxis (PEP). DESIGN: Retrospective cohort study including PrEP users with more than 12 months of follow-up before PrEP prescription and individuals receiving PEP from 2010 to 2015 at Clinique l'Actuel (Montréal, Canada). METHODS: Incidence of chlamydia, gonorrhoea, syphilis and hepatitis C virus over 12 months was compared before and after PrEP; and for PrEP versus PEP users using Poisson models to generate incidence rate ratios (IRRs) with 95% confidence intervals (CIs) and adjusted IRRs (aIRRs) controlling for frequency of STI-screening visits. Models comparing PrEP and PEP users were further adjusted for age and education. RESULTS: One hundred and nine PrEP and 86 PEP users were included. Increased rates of STIs were observed in the 12 months after PrEP relative to the 12 months prior (IRR: 1.72, CI: 1.22-2.41; aIRR: 1.39, CI 0.98-1.96). PrEP users were also at higher STI risk relative to PEP users (IRR: 2.18, CI: 1.46-3.24; aIRR: 1.76, CI: 1.14-2.71). CONCLUSION: Increased rates of STIs among individuals after initiation of PrEP may suggest greater risk behaviours during the first year on PrEP. Further studies are needed to measure long-term trends in STI acquisition following PrEP initiation.

2020· New England Journal of Medicine136doi:10.1056/nejmoa2009040

BACKGROUND: From November 2018 through February 2019, person-to-person transmission of Andes virus (ANDV) hantavirus pulmonary syndrome occurred in Chubut Province, Argentina, and resulted in 34 confirmed infections and 11 deaths. Understanding the genomic, epidemiologic, and clinical characteristics of person-to-person transmission of ANDV is crucial to designing effective interventions. METHODS: Clinical and epidemiologic information was obtained by means of patient report and from public health centers. Serologic testing, contact-tracing, and next-generation sequencing were used to identify ANDV infection as the cause of this outbreak of hantavirus pulmonary syndrome and to reconstruct person-to-person transmission events. RESULTS: After a single introduction of ANDV from a rodent reservoir into the human population, transmission was driven by 3 symptomatic persons who attended crowded social events. After 18 cases were confirmed, public health officials enforced isolation of persons with confirmed cases and self-quarantine of possible contacts; these measures most likely curtailed further spread. The median reproductive number (the number of secondary cases caused by an infected person during the infectious period) was 2.12 before the control measures were enforced and decreased to 0.96 after the measures were implemented. Full genome sequencing of the ANDV strain involved in this outbreak was performed with specimens from 27 patients and showed that the strain that was present (Epuyén/18-19) was similar to the causative strain (Epilink/96) in the first known person-to-person transmission of hantavirus pulmonary syndrome caused by ANDV, which occurred in El Bolsón, Argentina, in 1996. Clinical investigations involving patients with ANDV hantavirus pulmonary syndrome in this outbreak revealed that patients with a high viral load and liver injury were more likely than other patients to spread infection. Disease severity, genomic diversity, age, and time spent in the hospital had no clear association with secondary transmission. CONCLUSIONS: Among patients with ANDV hantavirus pulmonary syndrome, high viral titers in combination with attendance at massive social gatherings or extensive contact among persons were associated with a higher likelihood of transmission.

2015· The Journal of Infectious Diseases125doi:10.1093/infdis/jiv037

BACKGROUND: Tryptophan (Trp) catabolism into kynurenine (Kyn) contributes to immune dysfunction in chronic human immunodeficiency virus (HIV) infection. To better define the relationship between Trp catabolism, inflammation, gut mucosal dysfunction, and the role of early antiretroviral therapy (ART), we prospectively assessed patients early after they acquired HIV. METHODS: Forty patients in the early phase of infection were longitudinally followed for 12 months after receiving a diagnosis of HIV infection; 24 were untreated, and 16 were receiving ART. Kyn/Trp ratio, regulatory T-cells (Tregs) frequency, T-cell activation, dendritic cell counts, and plasma levels of gut mucosal dysfunction markers intestinal-type fatty acid-binding protein, soluble suppression of tumorigenicity 2, and lipopolysaccharide were assessed. RESULTS: Compared with healthy subjects, patients in the early phase of infection presented with elevated Kyn/Trp ratios, which further increased in untreated patients but normalized in ART recipients. Accordingly, in untreated subjects, the elevated Treg frequency observed at baseline continued to increase over time. The highest CD8(+) T-cell activation was observed during the early phase of infection and decreased in untreated patients, whereas activation normalized in ART recipients. The Kyn/Trp ratio was positively associated with CD8(+) T-cell activation and levels of inflammatory cytokines (interleukin 6, interferon γ-inducible protein 10, interleukin 18, and tumor necrosis factor α) and negatively associated with dendritic cell frequencies at baseline and in untreated patients. However, ART did not normalize plasma levels of gut mucosal dysfunction markers. CONCLUSIONS: Early initiation of ART normalized enhanced Trp catabolism and immune activation but did not improve plasma levels of gut mucosal dysfunction markers.

2012· The Journal of Infectious Diseases123doi:10.1093/infdis/jis104

BACKGROUND: The importance of human immunodeficiency virus (HIV) blip magnitude on virologic rebound has been raised in clinical guidelines relating to viral load assays. METHODS: Antiretroviral-naive individuals initiating combination antiretroviral therapy (cART) after 1 January 2000 and achieving virologic suppression were studied. Negative binomial models were used to identify blip correlates. Recurrent event models were used to determine the association between blips and rebound by incorporating multiple periods of virologic suppression per individual. RESULTS: 3550 participants (82% male; median age, 40 years) were included. In a multivariable negative binomial regression model, the Amplicor assay was associated with a lower blip rate than branched DNA (rate ratio, 0.69; P < .01), controlling for age, sex, region, baseline HIV-1 RNA and CD4 count, AIDS-defining illnesses, year of cART initiation, cART type, and HIV-1 RNA testing frequency. In a multivariable recurrent event model controlling for age, sex, intravenous drug use, cART start year, cART type, assay type, and HIV-1 RNA testing frequency, blips of 500-999 copies/mL were associated with virologic rebound (hazard ratio, 2.70; P = .002), whereas blips of 50-499 were not. CONCLUSIONS: HIV-1 RNA assay was an important determinant of blip rates and should be considered in clinical guidelines. Blips ≥500 copies/mL were associated with increased rebound risk.

Edmundo Casas, Leo Ramos, Eduardo Bendek, Francklin Rivas
2023· IEEE Access123doi:10.1109/access.2023.3312217

This paper presents a comprehensive evaluation of various YOLO architectures for smoke and wildfire detection, including YOLOv5, YOLOv6, YOLOv7, YOLOv8, and YOLO-NAS. The study aims to assess their effectiveness in early detection of wildfires using the Foggia dataset, comprising 8,974 images specifically designed for this purpose. Performance evaluation employs metrics such as Recall, Precision, F1-score, and mean Average Precision to provide a holistic assessment of the models’ performance. The study follows a rigorous methodology involving fixed epochs, continuous performance tracking, and unbiased testing. Results show that YOLOv5, YOLOv7, and YOLOv8 exhibit a balanced performance across all metrics in both validation and testing. YOLOv6 performs slightly lower in recall during validation but achieves a good balance on testing. YOLO-NAS variants excel in recall, making them suitable for critical applications. However, precision performance is lower for YOLO-NAS models. Visual results demonstrate that the top-performing models accurately identify most instances in the test set. However, they struggle with distant scenes and poor lighting conditions, occasionally detecting false positives. In favorable conditions, the models perform well in identifying relevant instances. We conclude that no single model excels in all aspects of smoke and wildfire detection. The choice of model depends on specific application requirements, considering accuracy, recall, and inference time. This research contributes to the field of computer vision in smoke and wildfire detection, providing a foundation for improving detection systems and mitigating the impact of wildfires. Researchers can build upon these findings to propose modifications and enhance the effectiveness of wildfire detection systems.

Atovaquone suspensions (750 mg and 1500 mg once a day) were compared with aerosolized pentamidine (300 mg once a month) for the prevention of Pneumocystis carinii pneumonia (PCP) in subjects with human immunodeficiency virus (HIV) infection who were intolerant to trimethoprim or sulfonamides (or both). Median time using the assigned therapy was 6.6 months, and the median follow-up was 11.3 months. Intent-to-treat analyses (n=549) showed no statistically significant differences among subjects with regard to the incidence of PCP (26%, 22%, and 17%, respectively) or mortality (20%, 13%, and 18%, respectively). The incidence of treatment-limiting adverse events with atovaquone was significantly higher (P<.01). There was, however, no significant difference in the time using therapy. Incidences of PCP and death were higher in subjects receiving 750 mg of atovaquone than in subjects receiving 1500 mg. Atovaquone suspension at 1500 mg once a day has an efficacy similar to that of aerosolized pentamidine for prevention of PCP in HIV-infected subjects and is a safe, effective alternative in those who are intolerant to trimethoprim or sulfonamides.

2019· Clinical Infectious Diseases85doi:10.1093/cid/ciz212

BACKGROUND: Microbial translocation from the gut to systemic circulation contributes to immune activation during human immunodeficiency virus (HIV) infection and is usually assessed by measuring plasma levels of bacterial lipopolysaccharide (LPS). Fungal colonization in the gut increases during HIV-infection and people living with HIV (PLWH) have increased plasma levels of fungal polysaccharide (1→3)-β-D-Glucan (βDG). We assessed the contribution of circulating DG to systemic immune activation in PLWH. METHODS: Cross-sectional and longitudinal assessments of plasma βDG levels were conducted along with markers of HIV disease progression, epithelial gut damage, bacterial translocation, proinflammatory cytokines, and βDG-specific receptor expression on monocytes and natural killer (NK) cells. RESULTS: Plasma βDG levels were elevated during early and chronic HIV infection and persisted despite long-term antiretroviral therapy (ART). βDG increased over 24 months without ART but remained unchanged after 24 months of treatment. βDG correlated negatively with CD4 T-cell count and positively with time to ART initiation, viral load, intestinal fatty acid-binding protein, LPS, and soluble LPS receptor soluble CD14 (sCD14). Elevated βDG correlated positively with indoleamine-2,3-dioxygenase-1 enzyme activity, regulatory T-cell frequency, activated CD38+Human Leukocyte Antigen - DR isotype (HLA-DR)+ CD4 and CD8 T cells and negatively with Dectin-1 and NKp30 expression on monocytes and NK cells, respectively. CONCLUSIONS: PLWH have elevated plasma βDG in correlation with markers of disease progression, gut damage, bacterial translocation, and inflammation. Early ART initiation prevents further βDG increase. This fungal antigen contributes to immune activation and represents a potential therapeutic target to prevent non-acquired immunodeficiency syndrome events.

2019· The Journal of Infectious Diseases81doi:10.1093/infdis/jiz423

BACKGROUND: Regenerating islet-derived protein 3α (REG3α) is an antimicrobial peptide secreted by intestinal Paneth cells. Circulating REG3α has been identified as a gut damage marker in inflammatory bowel diseases. People living with human immunodeficiency virus (PWH) on antiretroviral therapy (ART) present with an abnormal intestinal landscape leading to microbial translocation, persistent inflammation, and development of non-AIDS comorbidities. Herein, we assessed REG3α as a marker of gut damage in PWH. METHODS: Plasma from 169 adult PWH, including 30 elite controllers (ECs), and 30 human immunodeficiency virus (HIV)-uninfected controls were assessed. REG3α plasma levels were compared with HIV disease progression, epithelial gut damage, microbial translocation, and immune activation markers. RESULTS: Cross-sectionally, REG3α levels were elevated in untreated and ART-treated PWH compared with controls. ECs also had elevated REG3α levels compared to controls. Longitudinally, REG3α levels increased in PWH without ART and decreased in those who initiated ART. REG3α levels were inversely associated with CD4 T-cell count and CD4:CD8 ratio, while positively correlated with HIV viral load in untreated participants, and with fungal product translocation and inflammatory markers in all PWH. CONCLUSIONS: Plasma REG3α levels were elevated in PWH, including ECs. The gut inflammatory marker REG3α may be used to evaluate therapeutic interventions and predict non-AIDS comorbidity risks in PWH.

2005· Canadian Journal of Infectious Diseases and Medical Microbiology71doi:10.1155/2005/303141

Approximately two years after the introduction of highly active antiretroviral therapy for the treatment of HIV infection, body shape changes and metabolic abnormalities were increasingly observed. Initially, these were ascribed to protease inhibitors, but it is now clear that nucleoside reverse transcriptase inhibitors also contribute to lipodystrophy syndrome. The syndrome groups together clinical conditions describing changes in body fat distribution that include lipoatrophy, lipoaccumulation or both. However, there does not appear to be a direct link between lipoatrophy and lipoaccumulation that would support a single mechanism for the redistribution of body fat. Currently, there is no clear definition of lipodystrophy, which explains the difficulty in determining its prevalence and etiology. There are no current guidelines for the treatment of fat distribution abnormalities that occur in the absence of other metabolic complications. The present article reviews the current state of knowledge of the definition, symptoms, risk factors, pathogenesis, diagnosis and treatment of the morphological changes associated with lipodystrophy syndrome.

1983· American Journal of Medical Genetics71doi:10.1002/ajmg.1320140309

We report a brother and sister who died neonatally with a distinctive but variable multiple congenital anomaly (MCA) syndrome. Anomalies in both included similar facial changes, cleft palate, distal digital hypoplasia, lung hypoplasia, and urogenital abnormalities. They were discordant for cleft lip, diaphragmatic hernia, and Dandy-Walker anomaly. These sibs resemble three recently reported stillborn children and support the existence of a "new" autosomal recessive MCA syndrome with variable expressivity.

Pharmacokinetic considerations in Roux-en-Y gastric bypass patients

2011· American Journal of Health-System Pharmacy70doi:10.2146/ajhp100630

PURPOSE: Pharmacokinetic considerations in patients who have undergone Roux-en-Y gastric bypass (RYGB) are explored. SUMMARY: The prevalence of obesity, especially morbid obesity, has dramatically increased in recent years. In response, the number of bariatric surgeries performed has risen sharply, as this surgery is the technique demonstrated as being the most effective for sustained treatment of morbid obesity. RYGB, the most popular technique in the United States, combines the principle of restriction (dramatically decreasing stomach size) with malabsorption (bypassing the entire duodenum). It stands to reason that a decrease in gastric and intestinal absorptive surface area may considerably affect oral bioavailability of some drugs. Drugs that require a more acidic environment for absorption, uncoating, or activation and drugs that rely on intestinal transporters located in the duodenum for proper absorption would be most affected. Practitioners looking for guidance in tailoring pharmacotherapy to the RYGB patient will find little help in the primary literature at this time. Until more pharmacokinetic studies are available, practitioners may apply and log P of individual the principles of pK(a) drugs in the attempt to predict the potential impact of the RYGB on a drug's absorption. Likewise, if a drug relies on certain transporters located with highest frequency in the duodenum, alternative therapies can be selected that do not rely on such transport mechanisms for absorption. CONCLUSION: The pK(a), log P, and intestinal transport mechanisms should be considered when determining which drugs may have altered pharmacokinetics in patients who have undergone RYGB.

Early Initiation Rather Than Prolonged Duration of Antiretroviral Therapy in HIV Infection Contributes to the Normalization of CD8 T-Cell Counts
Wei Cao, Vikram Mehraj, Benoît Trottier, Jean-Guy Baril +4 more
2015· Clinical Infectious Diseases63doi:10.1093/cid/civ809

BACKGROUND: CD8 T-cell counts remain elevated in human immunodeficiency virus (HIV) infection even after long-term antiretroviral therapy (ART), which is associated with an increased risk of non-AIDS-related events. We assessed the impact of ART initiation in early versus chronic HIV infection on trajectories of CD8 cell counts over time. METHODS: Of 280 individuals enrolled during primary HIV infection (PHI), 251 were followed up for 24 months; 84 started ART before 6 months of infection (eART), 49 started between 6 and 24 months, and 118 remained untreated. Plasma HIV viral load (VL), CD4 and CD8 cell counts were assessed at each study visit. CD8 counts were also examined in 182 age-matched HIV-infected individuals who started ART during chronic infection and maintained undetectable plasma VL for ≥5 years. RESULTS: At PHI baseline, higher CD8 cell counts were associated with more recent infection (P = .02), higher CD4 cell counts (P < .001), and higher VL (P < .001). The CD8 count in the eART group decreased from 797 to 588 cells/µL over 24 months (P < .001), to a level lower than that in untreated PHI (834 cells/µL; P = .004) or in long-term-treated patients with chronic HIV infection (743 cells/µL; P = .047). More prominent CD4 T-cell recovery was observed in the eART group than in the delayed ART group. CONCLUSIONS: ART initiated in early HIV infection is associated with improved resolution of CD8 T-cell elevation compared with long-term ART initiated in chronic infection. Early ART may help reduce the risk of non-AIDS-related events by alleviating this elevation.

OBJECTIVE: This project was designed to provide an overview of hot flash studies conducted over the past two decades at the Mayo Clinic and in the North Central Cancer Treatment Group. DESIGN: Prospective clinical trials performed by these investigators are illustrated, described, and discussed. RESULTS: Ten randomized, controlled (eight placebo controlled), double-blind clinical trials were conducted involving a total of 1,581 women and three placebo-controlled, double-blind clinical trials involving a total of 329 men were conducted. In addition, 14 pilot trials, having involved more than 325 participants to date, were conducted. CONCLUSIONS: Data from the pilot trials have given direction for substances that ought to be further explored in more definitive studies. In men, randomized studies demonstrate that hot flashes are markedly decreased by low doses of megestrol acetate, moderately decreased by gabapentin, but not substantially decreased by clonidine. Results from the randomized trials in women demonstrate that hot flashes are markedly decreased by relatively low doses of progestational agents (megestrol acetate and medroxyprogesterone acetate), moderately decreased by venlafaxine, mildly to moderately decreased by fluoxetine, mildly decreased by clonidine, but not substantially decreased by vitamin E, a soy phytoestrogen product, or black cohosh. Last, the data investigated in these studies support the hypothesis that, for the treatment of hot flashes in women, the results of therapeutic maneuvers are similar regardless of whether the patient has a history of breast cancer and/or is taking tamoxifen.

Abstract The fashion industry often falls short of sustainability goals, but contemporary technological advancements offer a wide range of tools to address this issue. Artificial Intelligence (AI) has emerged as a particularly promising ally in promoting sustainability in fashion. This literature review explores how AI can contribute to the fashion industry’s sustainability, highlighting its potential benefits and limitations. Following PRISMA guidelines, we conducted a review of scientific documents, focusing on the period from 2010 to 2022. After a meticulous selection process, we analyzed 37 scholarly articles to distill their key insights and contributions. Our findings demonstrate that AI has diverse applications in different aspects of the fashion industry, enhancing sustainability efforts in supply chain management, creative design, sales and promotion, waste control, and data analysis. While AI offers significant potential, it is important to acknowledge limitations, such as the volume of data required and associated implementation costs. The reviewed literature aligns with the multifaceted nature of sustainability, emphasizing responsible resource management, accessible services, and efficient customer satisfaction, both now and in the future. In conclusion, despite some reservations, AI stands as a crucial partner in guiding the fashion industry toward a more sustainable future.

Ten questions concerning smart and healthy built environments for older adults

2023· Building and Environment47doi:10.1016/j.buildenv.2023.110720

In the past decade, the term ‘global aging’ has gained much attention among researchers, policymakers, civil societies, and governments worldwide. The continuous decline in fertility rates and increased life expectancy have resulted in an ongoing demographic transition where the share of adults aged 65 or older is increasing and outnumbering children younger than five years. In the United States and other developed countries, this rapid demographic transition is expected to continue to strain the existing health infrastructure as it becomes increasingly challenging to ensure healthy living environments for older adults. The ten questions and answers in this paper have been prepared by experts from gerontology, geriatrics, architectural engineering, and senior living operations to inform and characterize the current continuum of living environments and communities available to older adults. They also identify the common elements that influence the environmental needs of older adults and highlight factors (such as technical assistance, health equity gaps, and caregiver workforce development) that challenge the future of smart and healthy built environments for older adults. A special focus has been placed on contextualizing indoor environmental quality (IEQ) elements and smart building technologies for older individuals, caregivers, and their various requirements (perhaps in their own homes and communities). Together, these viewpoints create a new paradigm to assist in designing and managing intelligent, healthy built environments that respond to human demands. Although this paper focuses on factors in the United States, others can benefit from the framework incubated upon these experiences, making this effort relevant towards addressing global opportunities in environments for older adults.

Arun-Angelo Patil, Richard Andrews, Richard Torkelson
1995· Stereotactic and Functional Neurosurgery47doi:10.1159/000098741

Computed tomography (CT) scans provide three-dimensional information about intracranial structures, which can be used to place stereotactically guided radiofrequency (RF) lesions and destroy a targeted volume of tissue. This technique was used for lesioning of the corpus callosum (CC) or the amygdala-hippocampus complex (AHC) in 9 patients with intractable seizures. The procedures were monitored by intraoperative CT scans. Lesions were made in the AHC in 7 patients and the CC in 2 patients. In addition, multiple subpial transection (MST) was performed in 6 patients. The longest follow-up is 29 months with a median of 19 months. Five patients (56%) are free of seizures, 3 patients (33%) have greater than 90% reduction in seizure activity and 1 patient (11%) has greater than 50% but at most 90% reduction in seizure activity. There were no complications except for temporary hemiparesis following MST in 1 patient. The results suggest that stereotactic volumetric RF lesioning of the AHC and the CC may be safe and effective in controlling intractable seizures.

BACKGROUND: External application of clay facial masks is a cosmetic procedure generally used to reduce skin lesions and to improve overall skin condition. OBJECTIVE: Collecting pilot data about self-treatment with clay jojoba oil masks on participants with acne-prone, lesioned skin and acne. METHODS: Open, prospective, observational pilot study: Participants received written information, instructions, and questionnaires without direct contact with the study physician. For 6 weeks, they applied the masks 2-3 times per week. The primary outcome is the difference of skin lesions: baseline vs. after 6 weeks. RESULTS: 194 participants (192 female, 2 male, mean age (± SE) (32.3 ± 0.7 years) returned questionnaires and diaries. 133 of these participants returned complete and precise lesion counts (per-protocol (PP) collective). A 54% mean reduction in total lesion count was observed after 6 weeks of treatment with clay facial mask. Both inflammatory and non-inflammatory skin lesions were reduced significantly after treatment compared to baseline: Median counts (MC) of pustules per affected participant were reduced from 7.0 ± 0.9 to 3.0 ± 0.5 (mean individual reduction (MIR) = 49.4%), the MC of the papules from 3.5 ± 2.2 to 1.0 ± 0.4 (MIR = 57.3%), the MC of cysts from 2.0 ± 0.8 to 0.5 ± 0.4 (MIR = 68.6%) and the MC of comedones from 26.5 ± 6.3 to 16.0 ± 4.0 (MIR = 39.1%). DLQI-average score decreased from 5.0 ± 4.5 (mean ± SE) before to 2.1 ± 2.8 after treatment. CONCLUSIONS: The present study gives preliminary evidence that healing clay jojoba oil facial masks can be effective treatment for lesioned skin and mild acne vulgaris.
