Perceived Accuracy Around Undetectable = Untransmitable Among Sexual and Gender Minorities Using Smartphones in India.

Sexual and gender minorities (SGM) using online venues in India are usually not reached by government HIV interventions, remaining an understudied yet important population. We investigated sociodemographic characteristics, sexual behaviours along with familiarity, knowledge, and correlated factors around perceived accuracy of the Undetectable = Untransmittable (U = U) slogan. Grindr users in India completed an online, cross-sectional survey in May-June 2022. We included individuals ≥ 18 years old who reported sex with men (excluding those who were born female and or identified as cis-gender female). Associations with perceived U = U accuracy were estimated using adjusted prevalence odds ratios (aPOR) with 95% confidence intervals (95% CI). The survey was completed by 3,126 eligible participants. The median age was 28 years and most participants lived in urban areas and had graduate or postgraduate education. HIV prevalence was 3.1%. Only 14% reported familiarity with the U = U slogan and after an explanation was provided, 25% perceived it as completely accurate. This was associated with knowing their HIV status (HIV Negative aPOR 1.37 [95%CI 1.1, 1.71], HIV Positive aPOR 3.39 [95%CI 2.11, 5.46]), having heard of PrEP (aPOR1.58 [95%CI 1.29,1.92]) or have used PrEP (aPOR1.56 [95%CI 1.15, 2.12]) along with use of party drugs (aPOR1.51 [95%CI 1.0 2.10]), being in touch with NGOs (aPOR 1.61 [95%CI 1.27, 2.02], p < .001) and having attended LGBTQIA + events (aPOR1.38 [95%CI 1.1, 1.73]). SGMs in India had low familiarity and low perceived accuracy around U = U. Education about U = U and innovating new strategies to reach this hidden population could reduce stigma around HIV in India.

RESUMEN: Las minorías sexuales y de género (MSG) que utilizan sitios en línea en la India, generalmente no son alcanzadas por el gobierno a través de sus intervenciones contra el VIH aunque siguen siendo una población importante, pero poco estudiada. Se investigaron las características sociodemográficas, el comportamiento sexual y, adicionalmente, la familiaridad, el conocimiento y la percepción de exactitud sobre el eslogan Indetectable = Intransmisible (I = I). Los usuarios indios de Grindr completaron una encuesta transversal en línea entre mayo y junio del 2022. Se incluyeron a personas ≥ 18 años que informaron haber tenido relaciones sexuales con hombres (se excluyeron aquellas asignadas como mujer al nacer y que se identificaron como mujeres cisgénero). Las asociaciones con la precisión percibida de I = I se estimaron con razones de probabilidad de prevalencia ajustadas (aPR) con intervalos de confianza a 95% (IC 95%). En total, 3,126 participantes elegibles completaron la encuesta. La mediana de edad fue de 28 años, la mayoría vivían en áreas urbanas y eran graduados o posgraduados. La prevalencia del VIH fue de 3.1%. Solo 14% informó que conocía el eslogan I = I, pero incrementó a 25% después de que se proporcionó una explicación y lo percibieron como completamente exacto. Esto se asoció con conocer su estado serológico (aPR VIH negativo = 1.37 [IC 95%: 1.1, 1.71]; aPR VIH positivo = 3.39 [IC 95%: 2.11, 5.46]), tener conocimiento de la profilaxis preexposición (PrEP) (aPR = 1.58 [IC 95%: 1.29,1.92]), haber usado la PrEP (aPR = 1.56 [IC 95% 1.15, 2.12]), usado drogas con fines recreativos (aPR = 1.51 [IC 95%: 1.0, 2.10]), estar en contacto con las ONG (aPOR 1.61 [95%CI 1.27, 2.02], p < .001) y haber asistido a eventos LGBTIQA+ (aPR = 1.38 [IC 95%: 1.0, 2.10]). Las MSG en India tuvieron poco conocimiento y poca percepción de exactitud sobre el eslogan I = I. La educación sobre I = I y otras estrategias innovadoras de prevención para el VIH en esta población podría ayudar a reducir el estigma en torno a esta enfermedad en la India.

Engaging Family Members to Support Exclusive Breastfeeding, Responsive care, and Antiretroviral Therapy Adherence Among Families with Children who are HIV-Exposed and Uninfected.

Children who are HIV-exposed and uninfected (CHEU) are at increased risk for poor growth, health, and development compared to children who are HIV-unexposed and uninfected. To support families with CHEU, we assessed the acceptability of engaging family members to support women living with HIV (WLWH) with exclusive breastfeeding (EBF) and antiretroviral therapy (ART) adherence and to engage in responsive infant caregiving. We conducted trials of improved practices, a consultative research approach, that follows participants over time as they try recommended behaviors. We enrolled postpartum women in Lusaka, Zambia, who identified home supporters. At visit 1, WLWH were interviewed about current practices. At visit 2, WLWH and home supporters received tailored EBF, responsive care, and ART adherence counseling. At visit 3, WLWH and home supporters were interviewed about their experiences trying recommended practices for 2-3 weeks. Interview transcripts were analyzed thematically. Participants included 23 WLWH, 15 male partners, and 8 female family members. WLWH reported several barriers to EBF. The most common were fear of HIV transmission via breastfeeding-despite high ART adherence-and insufficient breastmilk. After counseling, WLWH reported less fear of HIV transmission and improved breastfeeding practices. Home supporters reported providing WLWH increased support for EBF and ART adherence and practicing responsive caregiving. Both male and female home supporters appreciated being included in counseling and more involved in caregiving, and WLWH valued the increased support. Families with CHEU need focused support. Tailored counseling and family support for WLWH show promise for improving EBF, responsive caregiving, and ART adherence.

The Pandemic of Coronary Heart Disease in South Asia: What Clinicians Need to Know.

PURPOSE OF REVIEW: South Asia has around 1/6th of the current global population. Epidemiological studies suggest that South Asians living in South Asia and diaspora are at an increased risk of premature atherosclerotic cardiovascular diseases (ASCVDs). This is due to an interplay of genetic, acquired, and environmental risk factors. Due to its increasing share of the global population, clinicians need to know the reasons for this early predisposition, and strategies for early identification and mitigation. RECENT FINDINGS: South Asians have earlier onset of cardiometabolic risk factors such as insulin resistance, hypertension, and central adiposity. This increased risk is seen in both native South Asians and the diaspora. South Asians have earlier onset of ASCVD due to an earlier onset of cardiometabolic risk factors. Health promotion and early identification of these risk factors are essential to mitigate this ongoing crisis.

"It comes altogether as one:" perceptions of analytical treatment interruptions and partner protections among racial, ethnic, sex and gender diverse HIV serodifferent couples in the United States.

BACKGROUND: Most HIV cure-related studies involve interrupting antiretroviral treatment to assess the efficacy of pharmacologic interventions - also known as analytical treatment interruptions (ATIs). ATIs imply the risk of passing HIV to sexual partners due to the loss of undetectable HIV status. There has been a notable lack of attention paid to perceptions of ATIs among racial, ethnic, sex and gender minorities, and HIV serodifferent couples. These populations are among those most impacted by HIV in the United States. Future HIV cure research paradigms should equitably include considerations from these groups. METHODS: From August - October 2020, we conducted in-depth interviews with 10 racial, ethnic, sex, and gender minority HIV serodifferent couples in geographically diverse regions of the United States to understand their perspectives about ATIs and partner protection measures to prevent secondary HIV transmissions because of participation in ATI studies. We used framework analysis to analyze the qualitative data. RESULTS: Of the 10 couples recruited, four identified as a gay couple, two as a gay and bisexual couple, two as a heterosexual couple, one as a gay and queer couple, and one as a queer couple. We found that HIV serodifferent couples in our study viewed ATIs as contradicting HIV treatment adherence messages. Couples expressed discomfort around ATIs in HIV cure research. They were concerned with the return of HIV detectability and worried ATIs might result in secondary HIV transmission. Participants were strongly in favor of using a range of partner protection measures during ATIs that included PrEP, HIV risk reduction counseling, and alternatives for penetrative sex practices. Couples also recommended that sex partners be consulted or involved as part of ATI trials. CONCLUSIONS: Our findings highlight new potential opportunities and strategies to mitigate risk of HIV transmission during ATIs among key groups historically under-represented in HIV cure research. Findings also underscore the relational aspects of ATI trials. We provide preliminary considerations for planning ATI trials with diverse HIV serodifferent partners. Future studies should continue to explore these issues among other types of partnerships, cultures, and socio-cultural settings.

Performance of a fast and high-resolution multi-echo spin-echo sequence for prostate T2 mapping across multiple systems.

PURPOSE: To evaluate the performance of a multi-echo spin-echo sequence with k-t undersampling scheme (k-t T2 ) in prostate cancer. METHODS: Phantom experiments were performed at five systems to estimate the bias, short-term repeatability, and reproducibility across all systems expressed with the within-subject coefficient of variation (wCV). Monthly measurements were performed on two systems for long-term repeatability estimation. To evaluate clinical repeatability, two T2 maps (voxel size 0.8 × 0.8 × 3 mm3 ; 5 min) were acquired at separate visits on one system for 13 prostate cancer patients. Repeatability was assessed per patient in relation to spatial resolution. T2 values were compared for tumor, peripheral zone, and transition zone. RESULTS: Phantom measurements showed a small bias (median = -0.9 ms) and good short-term repeatability (median wCV = 0.5%). Long-term repeatability was 0.9 and 1.1% and reproducibility between systems was 1.7%. The median bias observed in patients was -1.1 ms. At voxel level, the median wCV was 15%, dropping to 4% for structures of 0.5 cm3 . The median tumor T2 values (79 ms) were significantly lower (P < 0.001) than in the peripheral zone (149 ms), but overlapped with the transition zone (91 ms). CONCLUSIONS: Reproducible T2 mapping of the prostate is feasible with good spatial resolution in a clinically reasonable scan time, allowing reliable measurement of T2 in structures as small as 0.5 cm3 .

Assessing the scalability of low conductivity substrates for photo-electrodes via modelling of resistive losses.

When scaling up photo-electrochemical processes to larger areas than conventionally studied in the laboratory, substrate performance must be taken into consideration and in this work, a methodology to assess this via an uncomplicated 2 dimensional model is outlined. It highlights that for F-doped SnO2 (FTO), which is ubiquitously used for metal oxide photoanodes, substrate performance becomes significant for moderately sized electrodes (5 cm) under no solar concentration for state of the art Fe2O3 thin films. It is demonstrated that when the process is intensified via solar concentration, current losses become quickly limiting. Methodologies to reduce the impact of substrate ohmic losses are discussed and a new strategy is proposed. Due to the nature of the photo-electrode current-potential relationship, operation at a higher potential where the photo-current saturates (before the dark current is observed) will lead to a minimum in current loss due to substrate performance. Crucially, this work outlines an additional challenge in scaling up photo-electrodes based on low conductivity substrates, and establishes that such challenges are not insurmountable.

Optimal high b-value for diffusion weighted MRI in diagnosing high risk prostate cancers in the peripheral zone.

PURPOSE: To retrospectively determine the optimal b-value(s) of diffusion-weighted imaging (DWI) associated with intermediate-high risk cancer in the peripheral zone (PZ) of the prostate. MATERIALS AND METHODS: Forty-two consecutive patients underwent multi b-value (16 evenly spaced b-values between 0 and 2000 s/mm2 ) DWI along with multi-parametric MRI (MP-MRI) of the prostate at 3 Tesla followed by trans-rectal ultrasound/MRI fusion guided targeted biopsy of suspicious lesions detected at MP-MRI. Computed DWI images up to a simulated b-value of 4000 s/mm2 were also obtained using a pair of b-values (b = 133 and 400 or 667 or 933 s/mm2 ) from the multi b-value DWI. The contrast ratio of average intensity of the targeted lesions and the background PZ was determined. Receiver operator characteristic curves and the area under the curve (AUCs) were obtained for separating patients eligible for active surveillance with low risk prostate cancers from intermediate-high risk prostate cancers as per the cancer of the prostate risk assessment (CAPRA) scoring system. RESULTS: The AUC first increased then decreased with the increase in b-values reaching maximum at b = 1600 s/mm2 (0.74) with no statistically significant different AUC of DWI with b-values 1067-2000 s/mm2 . The AUC of computed DWI increased then decreased with the increase in b-values reaching a maximum of 0.75 around b = 2000 s/mm2 . There was no statistically significant difference between the AUC of optimal acquired DWI and either of optimal computed DWI. CONCLUSION: The optimal b-value for acquired DWI in differentiating intermediate-high from low risk prostate cancers in the PZ is b = 1600 s/mm2 . The computed DWI has similar performance as that of acquired DWI with the optimal performance around b = 2000 s/mm2 . LEVEL OF EVIDENCE: 4 J. Magn. Reson. Imaging 2017;45:125-131.

Evaluation of optimized breath-hold and free-breathing 3D ultrashort echo time contrast agent-free MRI of the human lung.

PURPOSE: To evaluate an optimized stack of radials ultrashort echo time (UTE) 3D magnetic resonance imaging (MRI) sequence for breath-hold and free-breathing imaging of the human lung. MATERIALS AND METHODS: A 3D stack of ultrashort echo time radials trajectory was optimized for coronal and axial lower-resolution breath-hold and higher-resolution free-breathing scans using Bloch simulations. The sequence was evaluated in 10 volunteers, without the use of contrast agents. Signal-to-noise ratio (SNR) mean and 95% confidence interval (CI) were determined from separate signal and noise images in a semiautomated fashion. The four scanning schemes were evaluated for significant differences in image quality using Student's t-test. Ten clinical patients were scanned with the sequence and findings were compared with concomitant computed tomography (CT) in nine patients. Breath-hold 3D spokes images were compared with 3D stack of radials in five volunteers. A Mann-Whitney U-test was performed to test significance in both cases. RESULTS: Breath-hold imaging of the entire lung in volunteers was performed with SNR (mean = 42.5 [CI]: 35.5-49.5; mean = 34.3 [CI]: 28.6-40) in lung parenchyma for coronal and axial scans, respectively, which can be used as a quick scout scan. Longer respiratory triggered free-breathing scan enabled high-resolution UTE scanning with mean SNR of 14.2 ([CI]: 12.9-15.5) and 9.2 ([CI]: 8.2-10.2) for coronal and axial scans, respectively. Axial free-breathing scans showed significantly higher image quality (P = 0.008) than the three other scanning schemes. The mean score for comparison with CT was 1.67 (score 0: n = 0; 1: n = 3; 2: n = 6). There was no significant difference between CT and MRI (P = 0.25). 3D stack of radials images were significantly better than 3D spokes images (P < 0.001). CONCLUSION: The optimized 3D stack of radials trajectory was shown to provide high-quality MR images of the lung parenchyma without the use of MRI contrast agents. The sequence may offer the possibility of breath-hold imaging and provides greater flexibility in trading off slice thickness and parallel imaging for scan time.

A Phase I Dosing Study of Ferumoxytol for MR Lymphography at 3 T in Patients With Prostate Cancer.

OBJECTIVE: The objective of our study was to determine the optimal dose of ferumoxytol for performing MR lymphography (MRL) at 3 T in patients with prostate cancer. SUBJECTS AND METHODS: This phase I trial enrolled patients undergoing radical prostatectomy (RP) with bilateral pelvic lymph node dissection (PLND). Three groups of five patients each (total of 15 patients) received IV ferumoxytol before RP with bilateral PLND at each of the following doses of iron: 4, 6, and 7.5 mg Fe/kg. Patients underwent abdominopelvic MRI at 3 T before and 24 hours after ferumoxytol injection using T2- and T2*-weighted sequences. Normalized signal intensity (SI) and normalized SD changes from baseline to 24 hours after injection within visible lymph nodes were calculated for each dose level. Linear mixed effects models were used to estimate the effects of dose on the percentage SI change and log-transformed SD change within visible lymph nodes to determine the optimal dose of ferumoxytol for achieving uniform low SI in normal nodes. RESULTS: One patient who was excluded from the study group had a mild allergic reaction requiring treatment after approximately 2.5 mg Fe/kg ferumoxytol injection whereupon the injection was interrupted. The 15 study group patients tolerated ferumoxytol at all dose levels. The mean percentage SI change in 13 patients with no evidence of lymph metastasis was -36.4%, -45.4%, and -65.1% for 4, 6, and 7.5 mg Fe/kg doses, respectively (p = 0.041). CONCLUSION: A dose level of 7.5 mg Fe/kg ferumoxytol was safe and effective in deenhancing benign lymph nodes. This dose therefore can be the starting point for future phase II studies regarding the efficacy of ferumoxytol for MRL.

Comparison of calculated and acquired high b value diffusion-weighted imaging in prostate cancer.

PURPOSE: To determine whether the performance of calculated high b value diffusion-weighted images (DWI) derived from regular lower b value DWI using exponential diffusion decay models (intravoxel incoherent motion = IVIM and diffusional kurtosis = DK) is comparable to acquired high b value DWI in prostate cancer detection. MATERIALS AND METHODS: One hundred six patients underwent diagnostic multiparametric prostate MRI at 3T using an endorectal coil. Five b value (b = 0, 188, 375, 563, 750 s/mm(2)) DWI and high b value (b = 0, 1000 and 2000 s/mm(2)) DWI were acquired. Calculated high b value (b = 1000 s/mm(2) and b = 2000 s/mm(2)) DWI were derived from the DWI dataset using DK and IVIM models. Calculated and acquired high b value DWI images were compared for lesion visibility and image quality by two experienced radiologists (1 and 6 years of experience). GEE with Wald test was used to compare the image quality among the four calculated high b value DWI by comparing the proportion of lesions in each model which were comparable to the acquired images. This comparison was done for all lesions and by lesion location (PZ or CG; low apical/anterior or apical/mid/base) RESULTS: More lesions were visible on acquired b = 2000 s/mm(2) compared to b = 1000 s/mm(2) DWI. Calculated high b value DWI using the IVIM model had approximately the same number of lesions as acquired high b value DWI, whereas the DK model had fewer lesions than acquired images. The image quality of calculated high b value DWI was comparable to that of acquired images, and the highest quality images were obtained with b1000IVIM. The image quality of calculated b1000IVIM was the same as that of acquired DWI in apical/mid/base (98%) locations and comparable in low apical and anterior (95.4%) locations. The image quality of calculated b2000IVIM was inferior in both apical/mid/base (86.2%) locations and comparable in low apical and anterior (83.9%) locations. CONCLUSION: Calculated high b value DWI obtained using IVIM model has same lesion visibility as that of acquired DWI. The image quality of calculated high b value DWI relative to corresponding acquired DWI decreases with increase in b value.

BGRL: Basal Ganglia inspired Reinforcement Learning based framework for deep brain stimulators.

Deep Brain Stimulation (DBS) is an implantable medical device used for electrical stimulation to treat neurological disorders. Traditional DBS devices provide fixed frequency pulses, but personalized adjustment of stimulation parameters is crucial for optimal treatment. This paper introduces a Basal Ganglia inspired Reinforcement Learning (BGRL) approach, incorporating a closed-loop feedback mechanism to suppress neural synchrony during neurological fluctuations. The BGRL approach leverages the resemblance between the Basal Ganglia region of brain by incorporating the actor-critic architecture of reinforcement learning (RL). Simulation results demonstrate that BGRL significantly reduces synchronous electrical pulses compared to other standard RL algorithms. BGRL algorithm outperforms existing RL methods in terms of suppression capability and energy consumption, validated through comparisons using ensemble oscillators. Results shown in the paper demonstrate BGRL suppressed the synchronous electrical pulses across three signaling regimes namely regular, chaotic and bursting by 40%, 146% and 40% respectively as compared to soft actor-critic model. BGRL shows promise in effectively suppressing neural synchrony in DBS therapy, providing an efficient alternative to open-loop methodologies.

Lower PrEP Retention among Young and Black Clients Accessing PrEP at a Cluster of Safety Net Clinics for Gay and Bisexual Men.

Young men of color who have sex with men are vulnerable to HIV and experience poor PrEP uptake and retention. We conducted a secondary data analysis and calculated adjusted Prevalence Odds Ratios (aPORs) for PrEP retention along with 95% CIs at 90, 180, and 360 days at an organization running safety net clinics in Texas for gay and bisexual men. We found statistically significant association with age, race, in-clinic versus telehealth appointments, and having healthcare insurance. White clients had an aPOR of 1.29 [1.00, 1.67] as compared to Black clients at 90 days. Age group of 18-24 had a lower aPOR than all other age groups except 55 or older at all three time periods. Clients who met providers in person had an aPOR of 2.6 [2.14, 3.19] at 90, 2.6 [2.2, 3.30] at 180 days and 2.84 [2.27, 3.54] at 360 days. Our findings highlight the need for population-specific targeted interventions.

Lower PrEP retention for black and young MSM in TexasOur study findings suggest that of all clients who start PrEP, Black clients and younger clients had a higher chance of not continuing PrEP as compared to White clients and older clients respectively. This analysis was done for a clinic that pre-dominantly offers services to gay and bisexual men. We also found that those who were attending clinic in person had higher chances of continuing. Further those who are insured also had higher chances of continuing.

Electrode Treatments for Redox Flow Batteries: Translating Our Understanding from Vanadium to Aqueous-Organic.

Redox flow batteries (RFBs) are a promising technology for long-duration energy storage; but they suffer from inefficiencies in part due to the overvoltages at the electrode surface. In this work, more than 70 electrode treatments are reviewed that are previously shown to reduce the overvoltages and improve performance for vanadium RFBs (VRFBs), the most commercialized RFB technology. However, identifying treatments that improve performance the most and whether they are industrially implementable is challenging. This study attempts to address this challenge by comparing treatments under similar operating conditions and accounting for the treatment process complexity. The different treatments are compared at laboratory and industrial scale based on criteria for VRFB performance, treatment stability, economic feasibility, and ease of industrial implementation. Thermal, plasma, electrochemical oxidation, CO2 treatments, as well as Bi, Ag, and Cu catalysts loaded on electrodes are identified as the most promising for adoption in large scale VRFBs. The similarity in electrode treatments for aqueous-organic RFBs (AORFBs) and VRFBs is also identified. The need of standardization in RFBs testing along with fundamental studies to understand charge transfer reactions in redox active species used in RFBs moving forward is emphasized.

Perceptions and experiences of daily and long-acting pre-exposure prophylaxis (PrEP) among MSM in India.

Oral pre-exposure prophylaxis (PrEP) is an effective HIV prevention strategy with high efficacy. An increased willingness to use PrEP among at-risk Indian men who have sex with men (MSM) population has been reported; however, little is known about their real experiences that guide their key motivators, facilitators, and barriers with using oral and Long-Acting (LA) Injectable PrEP. We recruited participants (n = 18) through active MSM social media networks. The interviews were conducted using teleconferencing software. Interview topics included participants' sources of knowledge, experiences accessing daily PrEP, safe-sex behaviors while on PrEP, barriers and facilitators around PrEP, long-term goals with PrEP, perceptions around LA PrEP, and discussion around decision-making to switch from oral PrEP to LA PrEP. Transcripts were coded according to interview topics, and key themes were analyzed using a topical data analysis approach. Participants (median age 28 years, ranging from 18 to 40) reported a high perceived risk of HIV. This increased perceived risk was a key motivator for oral PrEP uptake. Most participants shared that they accessed PrEP through non-profit organizations serving the MSM community, where doctor consultations and medication were either free or subsidized. Even when participants reported high adherence to oral PrEP, they expressed discontent with the requirement to take it daily. High condom usage was reported concomitantly with PrEP use among most participants, except for a few who preferred bareback sex. Participants shared that they would prefer to continue PrEP until they are in a monogamous, exclusive relationship. The cost and affordability remained recurring themes, and while participants could afford oral PrEP, they wished it was cheaper, making it more accessible to the community at large. Most participants did not have prior knowledge of LA injectable PrEP but welcomed the intervention, alluding to cost and availability as the key decision-making factors affecting switching. MSM from India we interviewed adopted oral PrEP as an additional HIV prevention strategy to condoms through non-profit and private channels. Cost and broader access remains a concern among the MSM community. More acceptability research about long-acting PrEP is needed among MSM in the Indian context, and it is recommended for government interventions to include oral PrEP groups at higher risk of HIV acquisition.

Anemia and its association with glycemia and transaminitis in patients with type 2 diabetes mellitus: A cross-sectional pilot study.

Background and Aims: Anemia impairs glucose homeostasis, affects glycemic control, and predisposes to complications in diabetics. It correlates with oxidative stress and increases the risk of developing microvascular and macrovascular complications. However, it is an underrecognized comorbidity in diabetics. This study was conducted to assess the prevalence of anemia in diabetic patients and compare the metabolic profiles of anemic and non-anemic diabetics. Methods: This is a cross-sectional study, conducted among type 2 diabetes (T2DM) patients, at the outpatient clinic. Patients with chronic kidney disease (CKD), known hematological disorders, and chronic inflammatory disorders were excluded. Results: Of the 97 patients, 37 (38.14%) were found to be anemic (hemoglobin (Hb): male <13 g/dl, female <12 g/dl). The mean values of fasting blood sugar (FBS) in low and normal mean corpuscular volume (MCV) patients were 265.9 ± 43.7 mg/dl and 157.2 ± 7.2 mg/dl, respectively (P = 0.0026), and those of postprandial blood sugar (PPBS) were 370.3 ± 58.4 mg/dl and 226.3 ± 10.1 mg/dl, respectively (P = 0.0015). It was found that 6 (22.2%) of 27 patients with raised alanine aminotransferase (ALT) had anemia against 27 (45.8%) of 59 patients with normal ALT (P = 0.03). The mean Hb levels in patients with raised and normal ALT were 13.31 ± 2.3 gm% and 12.2 ± 2.0 gm% (P = 0.03), respectively. Conclusions: Blood sugar may have a direct relationship with MCV in T2DM patients. Hb tends to relate to hepatic enzymes likely due to altered dietary patterns in anemics. Further larger studies on the effect of iron supplementation and dietary habits on glycemic control and hepatic steatosis are warranted.

"I Feel Like I Don't Even Have HIV Anymore"-Facilitators, Barriers, and Experience regarding Use of Long-Acting Injectable Antiretroviral Therapy Among Persons with HIV in North Carolina.

As access to long-acting injectable antiretroviral therapy (LAI ART) expands, understanding patient perceptions and experiences around LAI should inform equitable scale-up and effective implementation strategies. This study used qualitative research design relying on semi-structured interviews conducted among persons with HIV (PWH) who were either virally suppressed on oral treatment (n = 11) or had received at least one dose of injectables (n = 7). Approximately half of participants identified as male (10/18) and most identified as African American (17/18). Among participants on oral ART, many described the prospect of injectable treatment as likely convenient and discreet, relieving the stress of remembering to take daily pill. Nearly all had heard of LAI ART prior to the interview, often from television or internet commercials. Most were excited about less frequent dosing, though expressed concern about the logistics involved in coming to clinic every two months. Many expressed uncertainties regarding the relative effectiveness of LAI ART compared with oral therapy and were wary of potential pain related to injections. In contrast, all persons on LAI ART described injection-site soreness as manageable. In addition to acknowledging the convenience of every-two-month injections, some persons receiving LAI ART expressed relief by lifting the emotional stress of taking a daily-pill that reminded them of their HIV positive status. Emerging clinical trial data supports the individual and public health benefits of LAI ART, regardless of prior viral-suppression; our work adds to a growing body of literature demonstrating the potential psychological benefits associated with this novel treatment modality for PWH regardless of recent viral-suppression.

Gluten-free foods are expensive and nutritionally imbalanced than their gluten-containing counterparts.

OBJECTIVES: Nutritional quality of gluten-free (GF) food products is very important, as patients with celiac disease consume these products for lifelong. There is paucity of data on the nutritional content and cost of GF food products compared with their gluten-containing (GC) counterparts from India (Asia). DESIGN: After a detailed market survey, packaged and labeled GF food products (n=485) and their packaged GC counterparts (n=790) from the supermarkets of Delhi (India) and e-commerce websites were included. Nutritional content and cost/100 g food (in US dollars) were calculated using the information on food label. RESULTS: Gluten-free food products were 232% (range: 118% to 376%) more expensive than their GC counterparts. Energy content of all GF food products was similar to their GC counterparts, except cereal-based snacks (GF: 445 kcal vs. GC: 510 kcal, p<0.001). The protein content was significantly lower in GF pasta and macaroni products (single-grain: GF: 6.5 g vs. GC:11. 5 g, p-0.002; multigrain: GF:7.6 g vs. GC:11.5 g, p-0.027), cereal flours (single-grain: GF: 7.6 g vs. GC: 12.3 g, p<0.001; multigrain: GF:10.9 g vs. GC: 14.1 g, p-0.009) and nutritional bars (GF: 21.81 g vs. GC:26 g, p-0.028) than their GC counterparts. Similarly, the dietary-fiber content of GF pasta and macaroni products, cereal flours, cereal premix and nutritional bars of GF foods was significantly lower than their GC counterparts. Gluten-free bread and confectionary items, biscuits and cookies and snacks had higher total fats and trans-fat content than their GC counterparts. Gluten-free cereal-based snacks had higher sodium content than their GC counterparts (GF: 820 mg vs. GC:670 mg; p<0.001). CONCLUSION: GF foods are significantly more expensive, contain less protein and dietary fiber and higher fat, trans-fat and sodium than their GC counterparts. Strategies must be developed to reduce the cost and improve the nutritional profile of GF foods.

Characterizing long-acting injectable antiretroviral therapy eligibility and initiation at a safety net academic medical center in the southeastern United States.

Background: Long-acting injectable (LAI) cabotegravir/rilpivirine (CAB/RPV) extends dosing intervals from daily to every 8 weeks. Equitable implementation requires anticipating and addressing barriers to use. We described LAI-CAB/RPV eligibility and initiation among persons with HIV (PWH) receiving care at a Southeastern US academic medical center. Methods: We included PWH ≥18 years, in care 01/01/2020-12/31/2021, and participating in the UNC CFAR HIV Clinical Cohort. We characterized LAI-CAB/RPV eligibility, compared those with and without recent detectable viral load (VL), and described clinical outcomes on LAI-CAB/RPV. Results: Among 1672 PWH, 425 (25.4%) had LAI-CAB/RPV drug-resistance. Among 1238 LAI-eligible PWH, 8.9% had detectable VL. Median age was 53 (interquartile range 40, 61), 54.6% were non-Hispanic Black, and 73.6% male. Over one-third lived >50 miles from clinic, one-fifth were uninsured, and 7.4% reported hazardous alcohol use. Gaps in care (prior 12-month) were more common among PWH with detectable VL versus suppressed (23.1% vs 13.9%, p = 0.03). 6/47 initiated LAI-CAB/RPV had detectable VL prior to injection; >95% sustained suppression and those with detectable VL had a rapid decline in viremia. Conclusions: Three-quarters of PWH were eligible for LAI-CAB/RPV, but equitable implementation may require addressing challenges such as distance to care, inconsistent care engagement, and other comorbid conditions, particularly for PWH with viremia.

Prostate cancer: can multiparametric MR imaging help identify patients who are candidates for active surveillance?

PURPOSE: To determine whether multiparametric magnetic resonance (MR) imaging can help identify patients with prostate cancer who would most appropriately be candidates for active surveillance (AS) according to current guidelines and to compare the results with those of conventional clinical assessment scoring systems, including the D'Amico, Epstein, and Cancer of the Prostate Risk Assessment (CAPRA) systems, on the basis of findings at prostatectomy. MATERIALS AND METHODS: This institutional review board-approved HIPAA-compliant retrospectively designed study included 133 patients (mean age, 59.3 years) with a mean prostate-specific antigen level of 6.73 ng/mL (median, 4.39 ng/mL) who underwent multiparametric MR imaging at 3.0 T before radical prostatectomy. Informed consent was obtained from all patients. Patients were then retrospectively classified as to whether they would have met AS eligibility criteria or were better served by surgery. AS eligibility criteria for prostatectomy specimens were a dominant tumor smaller than 0.5 mL without Gleason 4 or 5 patterns or extracapsular or seminal vesicle invasion. Conventional clinical assessment scores (the D'Amico, Epstein, and CAPRA scoring systems) were compared with multiparametric MR imaging findings for predicting AS candidates. The level of significance of difference between scoring systems was determined by using the χ(2) test for categoric variables with the level of significance set at P < .05. RESULTS: Among 133 patients, 14 were eligible for AS on the basis of prostatectomy results. The sensitivity, positive predictive value (PPV), and overall accuracy, respectively, were 93%, 25%, and 70% for the D'Amico system, 64%, 45%, and 88% for the Epstein criteria, and 93%, 20%, and 59% for the CAPRA scoring system for predicting AS candidates (P < .005 for all, χ(2) test), while multiparametric MR imaging had a sensitivity of 93%, a PPV of 57%, and an overall accuracy of 92% (P < .005). CONCLUSION: Multiparametric MR imaging provides useful additional information to existing clinicopathologic scoring systems of prostate cancer and improves the assignment of treatment (eg, AS or active treatment).

Functional and molecular imaging of localized and recurrent prostate cancer.

Prostate cancer is the most common malignancy among American men. Imaging of localized and recurrent prostate cancer is challenging since conventional imaging techniques are limited. New imaging techniques such as multiparametric MRI and PET with targeted tracers have been investigated extensively in the last decade. As a result, the role of novel imaging techniques for the detection of localized and recurrent prostate cancer has recently expanded. In this review, novel functional and molecular imaging techniques used in the management of localized and recurrent prostate cancer are discussed.
