Electrocardiographic Abnormalities In Patients With Covid-19 Pneumonia And Raised Interleukin-6
Sinus tachycardia followed by atrial fibrillation and right bundle branch block are common ECG changes in patients with COVID-19 infection with raised IL-6.
KEY FINDINGS: Sinus tachycardia followed by atrial fibrillation and right bundle branch block are common ECG changes in patients with COVID-19 infection with raised IL-6. The possible association of cardiac injury in patients with COVID-19 infection with coexisting raised IL-6 levels should be explored further.
BACKGROUND: Cardiac injury is associated with high mortality in patients with COVID-19 infection. Electrocardiographic changes can give clues to the underlying cardiovascular abnormalities. Raised inflammatory markers like raised interleukin-6 (IL-6) are associated with arrhythmia, heart failure, and coronary artery disease. However, past studies have not highlighted the electrocardiographic abnormalities in patients with COVID-19 infection with raised IL- 6 levels. This study compared the electrocardiogram (ECG) changes in COVID-19 patients with high and normal IL-6 levels.
DETAILS: A retrospective analysis of ECG of 306 patients with COVID-19 infection was done, out of which 250 patients had normal IL- 6 levels, whereas 56 patients had raised IL-6 levels. IL-6 levels were measured in all the patients. Detailed clinicodemographic profile of all the serial COVID-19 patients admitted with moderate to severe COVID-19 pneumonia was noted from the hospital record section. Electrocardiographic findings and biochemical parameters of all the patients were noted. Out of 56 patients with raised IL-6 levels, 41 (73.2%) patients had ECG abnormalities compared to 177 (70.8%) patients with normal IL-6 levels. This difference was not statistically significant. However, ECG abnormality such as sinus tachycardia was significantly more common in patients with raised IL-6 levels than those with normal levels. Among patients with raised IL-6 levels who were discharged, 5 (16.6%) had sinus tachycardia, 2 (6.6%) had ST/T wave changes as compared to 15 (57.6%), and 10 (38.4%) who had tachycardia and ST/T wave change respectably succumbed to death. This difference was statistically significant.

KEY FINDINGS: Results of this systematic review and meta-analysis suggest that depressive disorders, anxiety disorders, PTSD, and sleep disorders were associated with an increased risk of ACS. Particularly, PTSD and sleep disorders emerged as significant risk factors for ACS, indicating the potential impact of sleep quality on cardiovascular outcomes. Future research addressing these limitations could provide more nuanced insights into the association between mental health and ACS.
BACKGROUND: Aim of this study is to estimate the association of ACS among patients with mental disorders, as compared with patients without mental disorders.
DETAILS: Study screening was performed in duplicates with conflicts resolved upon consensus. Inclusion criteria were as follows: (1) observational or randomized study, (2) measured association with ACS (incident events, risk ratio, odds ratio, hazard ratio [HR]), and (3) investigated any clinical mental disorder (based on DSM and International Classification of Diseases) before ACS events. This systematic review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. Data extraction was performed in duplicate and resolved on consensus. Data were quantitatively synthesized through random-effects meta-analysis. The National Institutes of Health Study Quality Assessment Tools were used to assess the quality of included studies. Studies were analyzed from January 1966 to October 2021. Among 3616 initially identified studies, 25 full-text articles met inclusion criteria with 22,048,504 participants of median (IQR) age 48.0 (34.5-56.1) years, with 13 019 897 males (59.1%). Depressive disorder (HR, 1.40; 95% CI, 1.11-1.78; P = .01; Grading of Recommendations Assessment, Development, and Evaluation [GRADE] certainty = very low), anxiety disorder (HR, 1.63; 95% CI, 1.40-1.89; P < .001; GRADE certainty = low), sleep disorder (HR, 1.60; 95% CI, 1.22-2.10; P < .001; GRADE certainty = low), and posttraumatic stress disorder (PTSD; HR, 2.73; 95% CI, 1.94-3.84; P < .001; GRADE certainty = moderate) were associated with increased risk of ACS. Bipolar (HR, 1.48; 95% CI, 0.47-4.61; P = .28; GRADE certainty = very low) and psychotic (HR, 0.97; 95% CI, 0.01-178.30; P = .06; GRADE certainty = very low) disorders were not significantly associated with increased risk of acute myocardial infarction, although they had similar point estimates to some other mental disorders.

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.
