Apolipoprotein A-IV Concentrations and Clinical Outcomes In A Large CKD Cohort
ApoA-IV appears to be an independent risk marker for reduced all-cause mortality, cardiovascular events and heart failure in a large cohort of patients with CKD.
KEY FINDINGS: The data support a link between elevated apoA-IV concentrations and reduced inflammation in moderate CKD. ApoA-IV appears to be an independent risk marker for reduced all-cause mortality, cardiovascular events and heart failure in a large cohort of patients with CKD.
BACKGROUND: Chronic kidney disease (CKD) represents a chronic proinflammatory state and is associated with very high cardiovascular risk. Apolipoprotein A-IV (apoA-IV) has antiatherogenic, antioxidative, anti-inflammatory and antithrombotic properties and levels increase significantly during the course of CKD. Study aimed to investigate the association between apoA-IV and all-cause mortality and cardiovascular outcomes in the German Chronic Kidney Disease study.
DETAILS: This was a prospective cohort study including 5141 Caucasian patients with available apoA-IV measurements and CKD. The majority of the patients had an estimated glomerular filtration rate (eGFR) of 30-60 ml/min/1.73m2 or an eGFR >60 ml/min/1.73m2 in the presence of overt proteinuria. Median follow-up was 6.5 years. The association of apoA-IV with comorbidities at baseline and endpoints during follow-up was modelled adjusting for major confounders. Mean apoA-IV concentrations of the entire cohort were 28.9 ± 9.8 mg/dl. Patients in the highest apoA-IV quartile had the lowest high-sensitivity C-reactive protein values despite the highest prevalence of diabetes, albuminuria and the lowest eGFR. Each 10 mg/dl higher apoA-IV translated into lower odds of prevalent cardiovascular disease (1289 cases, odds ratio = 0.80, 95% confidence interval [CI] 0.72-0.86, p = 0.0000003). During follow-up, each 10 mg/dl higher apoA-IV was significantly associated with a lower risk for all-cause mortality (600 cases, hazard ratio [HR] = 0.81, 95% CI 0.73-0.89, p = 0.00004), incident major adverse cardiovascular events (506 cases, HR = 0.88, 95% CI 0.79-0.99, p = 0.03) and death or hospitalizations due to heart failure (346 cases, HR = 0.84, 95% CI 0.73-0.96, p = 0.01).

KEY FINDINGS: In older adults with type 1 diabetes, CGM improves hypoglycemia; however, its role in improving IAH is variable, depending on the scoring method. This study highlights the limitations of the Clarke score.
BACKGROUND: Although continuous glucose monitoring (CGM) reduces hypoglycemia and may improve impaired awareness of hypoglycemia (IAH), its effectiveness in older adults at high risk remains unknown.
DETAILS: This post hoc analysis of the WISDM study focuses on CGM use over 52 weeks. IAH was assessed using the Clarke original score (Clarke-full) and its subscales, Hypoglycemia Awareness Factor (HAF) and Severe Hypoglycemia Experienced Factors (SHEF), at baseline, 26 weeks, and 52 weeks. After 26 weeks (n = 184) and 52 weeks (n = 94) of CGM use, Clarke-SHEF decreased significantly (P = 0.02 and P < 0.0001, respectively), whereas Clarke-full and Clarke-HAF remained unchanged. After 52 weeks, Clarke-full but not Clarke-HAF improved in the IAH subgroup, highlighting the importance of selecting the appropriate scoring method for IAH.

Efficacies of artemether-lumefantrine, artesunate-amodiaquine, dihydroartemisinin-piperaquine, and artesunate-pyronaridine for the treatment of uncomplicated Plasmodium falciparum malaria in children aged 6 months to 10 years in Uganda
Artemether-lumefantrine was associated with a higher risk of recurrent malaria than other antimalarial combinations tested, and K13 mutations were associated with delayed parasite clearance. Changes in first-line therapy for uncomplicated malaria must be considered in response to suboptimal efficacy of artemether-lumefantrine.

KEY FINDINGS: Artemether-lumefantrine was associated with a higher risk of recurrent malaria than other antimalarial combinations tested, and K13 mutations were associated with delayed parasite clearance. Changes in first-line therapy for uncomplicated malaria must be considered in response to suboptimal efficacy of artemether-lumefantrine.
BACKGROUND: Anti-malarial artemisinin-based combination therapies (ACTs) might be losing efficacy in east Africa, with the spread of artemisinin partial resistance and reduced partner drug activity. Our trial aimed to measure the efficacies of artemether-lumefantrine, artesunate-amodiaquine, dihydroartemisinin-piperaquine, and artesunate-pyronaridine in three sites in Uganda.
DETAILS: This randomised, open-label, phase 4 clinical trial was carried out at three sites in the Agago, Arua, and Busia districts of Uganda. Children aged 6 months to 10 years with uncomplicated Plasmodium falciparum malaria were randomly assigned to receive either artemether-lumefantrine (20 mg artemether; 120 mg lumefantrine; twice a day for 3 days) in all sites or dihydroartemisinin-piperaquine (40 mg dihydroartemisinin and 320 mg piperaquine, once a day for 3 days) in Agago, artesunate-amodiaquine (25 mg artesunate and 67.5 mg amodiaquine for children <9 kg or 50 mg artesunate and 135 mg amodiaquine for children >=9 kg, once a day for 3 days) in Busia; and artesunate-pyronaridine (60 mg artesunate and 180 mg pyronaridine for children >15 kg or 20 mg artesunate and 60 mg pyronaridine for children <15 kg, once a day for 3 days) in Arua, with follow-up to 42 days. Participants were not blinded to group assignments; however, investigators and those assessing outcome were masked. The primary outcome was parasitaemia, assessed by microscopy, either uncorrected or PCR-corrected to distinguish recrudescence from new infection. All participants who received the treatment per protocol and were not lost to follow-up were included in the primary outcome. All participants who were randomly allocated to treatment groups were included in the safety analyses. This study is registered with the Pan African Clinical Trials Registry, number PACTR202301796134887, and is complete. Between Nov 7, 2022, and March 24, 2023, 808 participants (437 [54%] female) were enrolled and assigned to treatment groups; 15 (2%) were lost to follow-up and 793 (98%) completed follow-up. The uncorrected adequate clinical and parasitological response for artemether-lumefantrine was 87 (51.8%; 95% CI 44.0-59.5) of 168 participants in Arua, 88 (51.8%; 44.0-59.4) of 170 and Busia, and 131 (79.4%; 72.3-85.1) of 165 in Agago. This response for artemether-lumefantrine was lower than that of the other ACTs at all sites: 97 (98.0%; 92.2-99.6) of 99 for dihydroartemisinin-piperaquine in Agago, 95 (99.0%; 93.5-99.9) of 96 for artesunate-amodiaquine in Busia, and 73 (73.7%; 63.8-81.8) of 99 for artesunate-pyronaridine in Arua. PCR-corrected 28-day efficacies were 88 (81.5%; 72.6-88.1) of 108 for artemether-lumefantrine and 95 (100%; 95.2-100.0) of 95 for artesunate-amodiaquine in Busia; 131 (97.0%; 92.1-99.0) of 135 for artemether-lumefantrine and 97 (100%; 95.3-100.0) of 97 for dihydroartemisinin-piperaquine in Agago; and 87 (82.1%; 73.2-88.6) of 106 for artemether-lumefantrine and 73 (92.4%; 83.6-96.9) of 79 for artesunate-pyronaridine in Arua. All regimens were well tolerated. The most common adverse events were upper respiratory tract infection, diarrhoea, and anaemia. None of the reported adverse events were attributed to the study drugs. There were two serious adverse events, both cases of severe malaria in Arua, one in each of the treatment groups. Parasite clearance half-lives were prolonged with parasites carrying the PfK13 Cys469Tyr (median 4.2 h; IQR 3.4-4.9) and Ala675Val (4.9 h; 3.4-5.7) mutations compared with wild-type parasites (2.8 h; 2.3-3.6; p<0.0001).

Medical Management and Revascularization for Asymptomatic Carotid Stenosis
Among patients with high-grade stenosis without recent symptoms, the addition of stenting led to a lower risk of a composite of perioperative stroke or death or ipsilateral stroke within 4 years than intensive medical management alone. Carotid endarterectomy did not lead to a significant benefit.
KEY FINDINGS: Among patients with high-grade stenosis without recent symptoms, the addition of stenting led to a lower risk of a composite of perioperative stroke or death or ipsilateral stroke within 4 years than intensive medical management alone. Carotid endarterectomy did not lead to a significant benefit.
BACKGROUND: Improvements in medical therapy, carotid-artery stenting, and carotid endarterectomy call into question the preferred management of asymptomatic carotid stenosis. Whether adding revascularization to intensive medical management would provide greater benefit than intensive medical management alone is unclear.
DETAILS: Authors conducted two parallel, observer-blinded clinical trials that enrolled patients with high-grade (>=70%) asymptomatic carotid stenosis across 155 centers in five countries. The stenting trial compared intensive medical management alone (medical-therapy group) with carotid-artery stenting plus intensive medical management (stenting group); the endarterectomy trial compared intensive medical management alone (medical-therapy group) with carotid endarterectomy plus intensive medical management (endarterectomy group). The primary outcome was a composite of any stroke or death, assessed from randomization to 44 days, or ipsilateral ischemic stroke, assessed during the remaining follow-up period up to 4 years. A total of 1245 patients underwent randomization in the stenting trial and 1240 in the endarterectomy trial. In the stenting trial, the 4-year incidence of primary-outcome events was 6.0% (95% confidence interval [CI], 3.8 to 8.3) in the medical-therapy group and 2.8% (95% CI, 1.5 to 4.3) in the stenting group (P=0.02 for the absolute difference). In the endarterectomy trial, the 4-year incidence of primary-outcome events was 5.3% (95% CI, 3.3 to 7.4) in the medical-therapy group and 3.7% (95% CI, 2.1 to 5.5) in the endarterectomy group (P=0.24 for the absolute difference). From day 0 to 44, in the stenting trial, no strokes or deaths occurred in the medical-therapy group and seven strokes and one death occurred in the stenting group; in the endarterectomy trial, three strokes occurred in the medical-therapy group and nine strokes occurred in the endarterectomy group.

KEY FINDINGS: The developed optical guidance system provides real-time feedback during laser lithotripsy, improving safety and precision by reducing the risk of accidental tissue damage. The proposed technology is expected to enhance outcomes in minimally invasive urological laser procedures.
BACKGROUND: Purpose of this study is to develop an optical feedback system compatible with a commercial surgical laser for automatically distinguishing between urinary stones and soft tissues during laser lithotripsy, thereby enhancing procedural safety.
DETAILS: The system, based on diffuse reflectance spectroscopy (DRS), was implemented in an engineered clinical theranostic platform. In vivo experiments were conducted to collect and analyze DRS spectra of tissues during laser lithotripsy. Illumination was performed via the endoscope, and detection was performed via the treatment fiber. Classification of urinary stones and soft tissues was performed using machine learning methods, i.e., Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA). The system demonstrated high diagnostic performance, with 93% sensitivity for soft tissue identification and 93% specificity for stone detection evaluated by the LDA method. This real-time differentiation effectively minimized unintended laser exposure to non-target tissues.

Hypopigmentation Following Picosecond Laser Treatment for Melasma
While hypopigmentation is rare with PSL treatment, it can occur even with conservative low-fluence settings and adequate intervals between sessions. One possible mechanism is thermal beam- stacking, where slow hand movement during treatment may lead to repeated pulses on the same area. This can result in localised thermal accumulation, potentially causing subcellular disruption of melanosomes without overt melanocyte loss.

KEY FINDINGS: While hypopigmentation is rare with PSL treatment, it can occur even with conservative low-fluence settings and adequate intervals between sessions. One possible mechanism is thermal beam- stacking, where slow hand movement during treatment may lead to repeated pulses on the same area. This can result in localised thermal accumulation, potentially causing subcellular disruption of melanosomes without overt melanocyte loss. These findings suggest the need for clinician vigilance in monitoring for hypopigmentation, as re-pigmentation may not be achievable. Larger, controlled studies are needed to clarify risk factors and guide safer practice.
BACKGROUND: Picosecond lasers (PSL) are increasingly used for treating melasma, with fewer adverse effects reported compared to Q-switched lasers (QSL). However, the incidence of hypopigmentation following PSL treatment remains unexplored in detail. This case series aims to explore outcomes of hypopigmentation following PSL therapy in patients with melasma, and explore potential contributing factors.
DETAILS: A retrospective chart review identified four patients with hypopigmentation following PSL treatment for melasma, including one referral from another clinic. Across the cohort, 796 patients underwent 3096 sessions between 2021 and 2025. Treatments used 755 and/or 1064-nm wavelengths at low fluences, with intervals of 4–12 weeks. Three in-clinic patients (0.38%, 95% CI 0.13%–1.10%) and one referral developed hypopigmentation. Changes occurred across both wavelengths and beam profiles. Histology demonstrated preserved melanocyte density with reduced melanin pigment and melanosome content. None of the cases showed meaningful re-pigmentation at 6-month follow-up. No cases of post-inflammatory hyperpigmentation (PIH) were observed.
