Abstract
Background Following reports of an outbreak of HIV infection among children in Larkana District, Pakistan, an international team investigated the extent and cause of the outbreak between April and June 2019. Aims To investigate the incidence of HIV among children in Larkana District, Pakistan and describe the distribution of cases by time, place and person. Methods Self-referred persons were tested for HIV using the national testing protocol. Local epidemiology of HIV was reviewed to generate hypotheses. An infection prevention and control (IPC) team conducted site visits and reviewed IPC practices. Results Between 25 April and 27 June 2019, a total of 30 191 persons were tested for HIV in Larkana District, and 876 of them tested positive. Of those who tested positive, 719 (82%) were children aged <15 years. Traditional skin piercing procedures and transmission from high-risk populations to children were ruled out during the investigation. Informative interviews with parents or guardians of a convenience sample of 211 children aged <15 years showed that 99% of children had an injection or infusion for medical treatment within the past 12 months. Our investigation identified lack of HIV prevalence data for the general population including tuberculosis patients and those who attended antenatal care services. Conclusions Investigations indicate that unsafe healthcare practices in formal and informal healthcare settings as the most likely cause of the 2019 outbreak of HIV infection in Larkana, Pakistan. Measures should be taken to improve IPC practices at the facility level, especially in pediatric and antenatal care clinics.

Abstract
Abstract Environmental contamination with heavy metals is a threat to the organisms due to their toxicity, persistence and bioaccumulation in food chains. The study was aimed to assess cadmium (Cd) effect on calcium (Ca) level in bones of a freshwater fish Channa gachua. 42 fish individuals were kept into six (6) aquaria; labelled aq.0, 1, 2, 3,4 and 5 in the laboratory for treatment. Aq.0 was control group and aq.1, 2,3,4,5 were experimental with treatment solution of Cd 0, 0.1ppm, 0.5ppm, 1ppm, 2.5ppm and 5ppm respectively for three months. After exposure, bones tissue were examined for Cd accumulation and Ca concentration. Highest accumulation of Cd were recorded in aq.5 mean 46.86 ± 0.46 mgkg-1 .and lowest in the control group with mean 0.61 ± 0.06 mgkg-1. The order of Cd bioaccumulation in bones were aq.5 > aq.4 >aq.3 > aq.2 > aq.1 > aq.0. Highest concentration of Ca were noted in aq.0 (Control group) mean 7888.06 ± 4827.22 mgkg-1 and lowest were 1132.36 ± 203.73 mgkg-1 in aq.5 (at 5.0 ppm). Generally a pattern of decreasing Ca level were observed with each rise of Cd bioaccumulation aq.0 > aq.1 > aq.2 > aq.3 > aq.4 > aq.5. Current study indicated that Cd accumulation have substantial effect on Ca level in bones and hence on skeleton system. Strict rules must be implemented by government to control metals pollution and exploitations of biota.

Abstract
The poultry industry generates a lot of waste, including dead birds, manure, and poultry litter. Poultry waste should never be disposed of improperly because it can seriously harm the environment. The waste can be recycled as a feedstock for use in poultry feed by composting the litter and deceased birds. The compositional profile and organoleptic properties of the meat of growing Japanese quail were examined over the course of a 4-week trial to ascertain the effect of adding compost to the diet. In a completely randomized design (CRD), 1200 newly hatched quail chicks (Coturnix coturnix japonica) were divided into five treatment groups (diets with 0, 2.5, 5, 7.5, and 10% compost), each consisting of 40 birds with six replicates. The addition of compost to the diet had no noticeable effects on the organoleptic qualities of appearance, color, aroma, taste, texture, juiciness, tenderness, and acceptability (P>0.05). The compositional profile characteristics for chicks given compost at any level compared to chicks fed the control diet showed no differences (P>0.05). These findings suggest that the sensory characteristics and compositional profile of growing meat quails can be maintained when fed diets including up to 10% compost.

Abstract
OBJECTIVE Polycystic ovary syndrome (PCOS) is a prevalent health condition that commonly affects adolescent girls and young women. The purpose of this study was to evaluate the correlation between levels of total glutathione (TG), reduced glutathione (GSH), superoxide dismutase (SOD), lipid peroxidation, and homocysteine with PCOS. PATIENTS AND METHODS This study employed a cross-sectional case-control design, involving a target population of 305 Sudanese females. Among them, 205 individuals were categorized as cases, and 100 served as controls. The TG, GSH, SOD, lipid peroxidation, and homocysteine levels were measured in the serum of study participants through enzyme-linked immunosorbent essay. RESULTS Total glutathione (1,174.5 ± 271.4 vs. 986.1 ± 191.5, p = 0.01), GSH (801.3 ± 132.2 vs. 748.6 ± 103.1, p = 0.007), SOD (225.2 ± 57.8 vs. 195.5 ± 49.6, p = 0.009), lipid peroxidation (3.4 ± 1.1 vs. 2.4 ± 0.7, p = 0.03), and homocysteine (14.9 ± 2.1 vs. 13.5 ± 1.6, p = 0.04), showed significant differences between the two groups (cases vs. controls). A moderate positive correlation between TG, GSH, SOD, lipid peroxidation, homocysteine, BMI, age, and duration of PCOS was observed. Furthermore, a strong positive correlation between BMI, age, and duration of PCOS was noted within the patient group. CONCLUSIONS In conclusion, this study demonstrates that patients with PCOS have elevated levels of TG, GSH, SOD, lipid peroxidation, and homocysteine compared to the control group. These findings suggest a potential association between PCOS and oxidative stress, lipid metabolism, and homocysteine pathways. Moreover, the observed positive correlation with BMI, age, and duration of PCOS indicates the importance of these factors in disease progression.

Abstract
BACKGROUND In sub-Saharan Africa, more women than men access HIV testing and treatment and may have better viral load suppression (VLS). We utilized routinely reported aggregated HIV program data from 21 sub-Saharan African countries to examine sex differences in VLS and death rates within antiretroviral therapy (ART) programs supported by the United States President's Emergency Plan for AIDS Relief (PEPFAR). METHODS We included VLS and reported death data for persons aged 15 + years on ART from October-December 2020 disaggregated by sex and age for each subnational unit (SNU). We used linear mixed-model regression to estimate VLS proportion and negative binomial mixed-model regression to estimate the rates of death and death plus interruptions in treatment (IIT). All models were weighted for SNU-level ART population size and adjusted for sex, age, HIV/tuberculosis coinfection, country, and SNU; models for reported deaths and deaths plus IIT were also adjusted for SNU-level VLS. RESULTS Mean VLS proportion was higher among women than men (93.0% vs. 92.0%, p-value < 0.0001) and 50 + than 15-49 age group (93.7% vs. 91.2%, p-value < 0.0001). The mean rate of reported deaths was higher among men than women (2.37 vs. 1.51 per 1000 persons, p-value < 0.0001) and 50 + than 15-49 age group (2.39 vs. 1.50 per 1000, p-value < 0.0001); the mean rate of reported deaths plus IIT was higher among men (30.1 in men vs. 26.0 in women per 1000, p-value < 0.0001) and higher among 15-49 than 50 + age group (34.7 vs. 22.6 per 1000, p-value < 0.0001). CONCLUSIONS The mean rate of reported deaths was higher among men in most models despite adjusting for VLS. Further exploration into differences in care-seeking behaviors; coverage of screening, prophylaxis, and/or treatment of opportunistic infections; and more extensive testing options for men to include CD4 is recommended.

Abstract
PURPOSE/OBJECTIVE(S) To investigate the tolerance level and toxicity for standard of care treatment for oropharyngeal cancer (OP) in elderly patients and their impact on outcomes. MATERIALS/METHODS Using our in-house head and neck cancer database, we looked for non-metastatic OP cases that received definitive treatment between 1/2009-6/2020. All patients received either definitive radiation therapy (RT) +/- concomitant systemic therapy (ST), or surgery followed by adjuvant RT or RT-ST. For the elderly (age at diagnosis ≥65 years) and young (<65 years) patients, we compared treatment package time (TPT) (time from surgery to RT conclusion) for adjuvant RT, total RT duration and unplanned RT interruptions. ST details and dose/protocol modifications were also compared. We evaluated worst grade of pain and mucositis, hospitalization for non-hydration causes and febrile neutropenia (FN) during RT. Feeding tube (FT) use and weight loss were compared. The independent effect of these indicators on locoregional (LRFS), distant (DRFS) recurrence free and overall (OS) survival was assessed using multivariate analyses (MVA). RESULTS A cohort of 326 patients was included: 36% elderly (n = 118) and 64% young (n = 208), with no differences in AJCC stage distribution (8th), treatment received and HPV status (HPV+ve: 73% vs 74.6%; p = 0.86). In 23.6 % who received adjuvant RT, median TPT was 86 (range 72-128) and 81 (65-137) days for elderly vs young (p = 0.27); whereas in the definitive RT cases 76.4%, total RT duration was 49 days for both age groups. Overall, prescribed RT course was not completed in 4% and unplanned RT interruptions occurred in 22.8% and both were non-significant between age groups. Among the 261 patients that received ST, elderly utilized more cetuximab (26 vs 12%; p = 0.007). For those who received cisplatin, 20% of elderly had cumulative dose <200 mg/m2 compared to 6% among the younger age group (p = 0.006); and cisplatin was changed to carboplatin or cetuximab in 18% vs 8% (p = 0.019). Delayed/cancelled cycles and dose reductions were similar. There were more hospitalizations (47% vs 27%; p<0.001) and a trend for more FN (9% vs 3%; p = 0.09) with older age, while worst pain and mucositis was similar. FTs were used more in elderly patients (64% vs 50%; p = 0.02), for a median of 97 vs 64 days (p = 0.31); of which 19.5% vs 11% (p = 0.28) were inserted before RT start. However, % weight loss was non-significant. On MVA, longer RT duration, FT use and hospitalizations predicted worse LRFS and DRFS; and they were prognostic for OS in addition to TPT >90 days (p<0.05 for all). Nevertheless, elderly vs young had non-significant 3-year LRFS (91% vs 90% and 67% vs 69%), DRFS (86% vs 90% and 79% vs 81%) & OS (85% vs 81% and 39% vs 52%) for HPV+ve and HPV-ve respectively (p>0.05). CONCLUSION Elderly patients with OP need more multi-disciplinary supportive care when receiving RT and concurrent ST. However, survival outcomes are equivalent to younger patients. Ongoing studies should enroll more elderly candidates and stratify endpoints with age.

Abstract
PURPOSE/OBJECTIVE(S) Patients with R/R acute leukemia after allogeneic hematopoietic cell transplant (alloHCT) have a dismal prognosis with 3-year survival rates of < 20%. To improve outcomes, innovative targeted forms of organ sparing radiotherapy, such as tumor-specific RIT and TMLI, are needed to dose escalate with acceptable toxicities, especially in patients ≥ age 60 years who cannot tolerate total body irradiation (TBI) / myeloablative regimens and who have a poor prognosis. CD25 is an ideal RIT target given its expression in acute leukemias, association with poor prognosis, and expression by leukemia stem cells. In this phase I trial (NCT05139004) we hypothesized that combining dose escalated 90Y-anti-CD25 RIT with fixed dose TMLI 12 Gy, fludarabine (flu), and melphalan (mel) in patients with R/R disease is safe and associated with acceptable toxicities. MATERIALS/METHODS The primary objective of this trial is to determine the maximum tolerated dose and recommended phase 2 dose of 90Y-anti-CD25 Mab (Day -15) with 12 Gy TMLI (1.5 Gy twice a day, days -8 to -5), flu (30 mg/m2/d days -5 to -2), and mel (100 mg/m2, day -2) in patients ≥ 60 years old or with a HCT-comorbidity index ≥ 2 and with R/R AML, ALL or myelodysplastic syndrome (MDS) scheduled to undergo alloHCT from a matched donor. TMLI mean organ dose constraints for kidney, lung and liver were 4 Gy. Planned dose levels of 90Y-anti-CD25 were 0.3, 0.4, and 0.5 mCi/kg. 111In-anti-CD25 (5 mCi) was co-infused followed by serial nuclear scans to assess dosimetry and biodistribution. RESULTS To date 5 patients (ages 31-74) with R/R AML have been treated. Marrow and circulating blasts ranged from 10-36% and 9-44%, respectively. For the 3 patients at 0.3 mCi/kg, follow-up ranged from 89-191+ days. 90Y/111In-anti-CD25 nuclear scans demonstrated persistent uptake in bone out to 144 hours, which was associated with a decline in circulating blasts. After combined RIT and TMLI, mean doses (Gy) to lungs ranged from 5.7-6.5, to kidneys from 7.5-8.2 and to liver from 7.2-11.6. No dose-limiting toxicities (DLT) were observed. All 3 patients achieved CR on day +30 bone marrow biopsies and 2 remained in CR on day +90 biopsies. Two patients have recently been treated at the 0.4 mCi/kg dose level. The results of patients treated at the higher dose levels will be provided. CONCLUSION Dose escalation by adding 90Y-anti-CD25 RIT at 0.3 mCi/kg to 12 Gy TMLI was safe, including in older patients, with no dose-limiting toxicities, mean critical organ doses lower than conventional myeloablative TBI, and encouraging response rates. The toxicity profile and dose estimates at 0.3 mCi/kg predict that the planned higher dose levels will also be feasible with acceptable toxicities. RIT and TMLI are complementary and when combined address the limitations of each modality. Combining these targeted therapies may be a superior strategy to intensify dose to leukemia compared to dose escalation of either modality alone.

Abstract
Background: Myocardial infarction (MI) is the main cause of illness, mortality, and stress worldwide. Oxidative stress is the major cause of myocardium tissue damage associated with cell necrosis. Objectives: The current study was designed to compare biochemical parameters with in vitro antioxidant activity in MI patients. Methods: This observational cohort study was conducted on 53 MI patients, and the samples were collected on the basis of a non-random sampling technique from April 2022 to November 2022. Lipid profile (i.e., total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), very-low-density lipoprotein (VLDL), and triglycerides (TG)) and cardiac profile (i.e., troponin T, troponin I, creatine kinase MB (CK-MB), and creatine phosphokinase (CPK)) were measured for the confirmation of variation in biochemical parameters. Afterward, the inhibition of oxidative stress was analyzed through the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay on the serum samples of the patients. Results: Of 53 MI patients, 33 and 20 cases were male and female, respectively. Moreover, the correlation of the DPPH assay with TC, troponin T, and troponin I was determined by Pearson correlation. The correlation coefficients range from -1 to 1, indicating the strength and direction of the linear relationship between the markers. The concentrations of lipid profile (i.e., TC, TG, LDL, and VLDL) or cardiac profile (i.e., CK-MB, CPK, troponin T, and troponin I) were significantly elevated in all MI patients. However, the HDL level (P = 0.001) was decreased. Conclusions: According to obtained results, reactive oxygen species (ROS) might be the causative agent of MI. Therefore, if an antioxidant medication is used as administrative content, it would be helpful for the treatment of MI and a lead mark for pharmaceutical companies in drug designing for MI patients.

Abstract
Minimizing leakage from computational states is a challenge when using many-level systems like superconducting quantum circuits as qubits. We realize and extend the quantum-hardware-efficient, all-microwave leakage reduction unit (LRU) for transmons in a circuit QED architecture proposed by Battistel et al. This LRU effectively reduces leakage in the second- and third-excited transmon states with up to 99% efficacy in 220 ns, with minimum impact on the qubit subspace. As a first application in the context of quantum error correction, we show how multiple simultaneous LRUs can reduce the error detection rate and suppress leakage buildup within 1% in data and ancilla qubits over 50 cycles of a weight-2 stabilizer measurement.

Abstract
Intravenous immune globulin (IVIg) therapy has been shown to be useful in a multitude of disorders. IVIg is produced from pooled human plasma; therefore, autoantibodies found in the general population are also present in IVIg and transferred to those being transfused. This can prove a particular hazard for screening and diagnostic tests based on autoantibodies. We present a patient who was found to have a positive antinuclear antibody (ANA) titer after multiple IVIg transfusions, resulting in diagnostic confusion and unnecessary workup. A 45-year-old gentleman was diagnosed with atypical CIDP, initiated on a course of IVIg, and sent for inpatient rehabilitation. However, recovery was complicated by multiple readmissions for recurrent weakness, and as part of the workup for other etiologies, an ANA was found to be positive. Sub-serologies and paraneoplastic autoantibody panel were negative. In the absence of clinical symptoms, we recommended continued monitoring and repeat ANA testing 6 months after the last dose of IVIg; as any drug needs 5 half-lives to be eliminated from the body. Clinicians should consider any recent IVIg treatments when evaluating the pre-test probability of detecting an underlying connective tissue disease with ANA screening. Indiscriminate ANA levels in patients recently given IVIg lead to unnecessary and expensive further testing and consultation.

Abstract
During the COVID-19 pandemic, public health agencies implemented an array of technologies and digital tools to support case investigation and contact tracing. Beginning in May 2020, the Association of State and Territorial Health Officials compiled information on digital tools used by its membership, which comprises 59 chief health officials from each of the 50 states, 5 US territories, 3 freely associated states, and the District of Columbia. This information was presented online through a publicly available technology and digital tools inventory. We describe the national landscape of digital tools implemented by public health agencies to support functions of the COVID-19 response from May 2020 through May 2021. We also discuss how public health officials and their informatics leadership referenced the information about the digital tools implemented by their peers to guide and refine their own implementation plans. We used a consensus-based approach through monthly discussions with partners to group digital tools into 5 categories: surveillance systems, case investigation, proximity technology/exposure notification, contact tracing, and symptom tracking/monitoring. The most commonly used tools included the National Electronic Disease Surveillance System Base System (NBS), Sara Alert, REDCap, and Maven. Some tools such as NBS, Sara Alert, REDCap, Salesforce, and Microsoft Dynamics were repurposed or adapted for >1 category. Having access to the publicly available technology and digital tools inventory provided public health officials and their informatics leadership with information on what tools other public health agencies were using and aided in decision making as they considered repurposing existing tools or adopting new ones.

Abstract
OBJECTIVES Exposure notification (EN) supplements traditional contact tracing by using proximity sensors in smartphones to record close contact between persons. This ledger is used to alert persons of potential SARS-CoV-2 exposure, so they can quarantine until their infection status is determined. We describe a model that estimates the impact of EN implementation on reducing the spread of SARS-CoV-2 and on the workload of public health officials, in combination with other key public health interventions such as traditional contact tracing, face mask wearing, and testing. METHODS We created an agent-based model, Simulated Automated Exposure Notification (SimAEN), to explore the effectiveness of EN to slow the spread of SARS-CoV-2. We varied selected simulation variables, such as population adoption of EN and EN detector sensitivity configurations, to illustrate the potential effects of EN. We executed 20 simulations with SimAEN for each scenario and derived results for each simulation. RESULTS When more sensitive versus more specific EN configurations were compared, the effective reproductive number, RE, was minimally affected (a decrease <0.03). For scenarios with increasing levels of EN adoption, an increasing number of additional infected persons were identified through EN, and total infection counts in the simulated population decreased; RE values for this scenario decreased with increasing EN adoption (a decrease of 0.1 to 0.2 depending on the scenario). CONCLUSIONS Estimates from SimAEN can help public health officials determine which levels of EN adoption in combination with other public health interventions can maximize prevention of COVID-19 while minimizing unnecessary quarantine in their jurisdiction.

Abstract
Abstract
Study question
We investigated the effect of monitoring and follow-up of serum progesterone, estradiol & luteinizing hormone levels and progesterone supplement adjustments on pregnancy outcomes for FET in programmed HRT cycles.
Summary answer
Monitoring and follow-up of different hormones in patient’s serum in programmed frozen embryo transfer cycles didn’t have an impact on overall pregnancy rate.
What is known already
Frozen Embryo transfer treatment rapidly expanded in recent years. FET can effectively prevent IVF associated complications, such as ovarian hyperstimulation syndrome and multiple pregnancy. In addition, FET serves as a safe & cost-effective way to increase cumulative pregnancy rate.
Though progesterone levels on the day of transfer have not yet been studied extensively in humans, tailoring the time of transferring a frozen embryo based on serial P4 values rather than cycle day number alone results in higher pregnancy rates.The value of measuring the serum E2 levels on the day of embryo transfer as an indicator for clinical pregnancy is still doubtful.
Study design, size, duration
Six Hundred FETs were performed in a randomized prospective manner in an infertility center in Alexandria starting from 2019 till 2021.These were further subdivided based on computer randomization into Group I (Non-intervention) including300 patients with only ultrasound monitoring & Group II (intervention) including 300 patients with monitoring of serum level of progesterone, estrogen & luteinizing hormone as well as progesterone supplement adjustments.
Participants/materials, setting, methods
Group I (Non-intervention) including300 patients with only ultrasound monitoring & Group II (intervention) including 300 patients with monitoring of serum level of progesterone, estrogen & luteinizing hormone as well as progesterone supplement adjustments which are further subdivided into three groups depending on progesterone level in patient’s serum early in the morning prior to embryo transfer. Group II A: P4 levels < 5ng/dl, Group II B: P4 levels 5-10ng/dl, Group II C: P4 levels >10ng
Main results and the role of chance
Live birth and overall pregnancy rate showed no significant difference among group monitored with ultrasound only compared to the hormonal monitored group. However, on the day of embryo transfer, serum P4 > 11.83 ng/ml represented a cut-off value above which there is marked increase in OPR/LBR and a sensitivity of 53.7% & specificity of 51.2% in predicting pregnancy. Also, serum E2 value more than 292 pg/ml at day 18 demonstrated an increase in OPR/LBR.In our study, the cut off value of LH level less than of 10.8 IU/L at day13 had a sensitivity of 58.3% & specificity of 50.4% in predicting pregnancy. Regarding pregnancy outcome, monitoring of LH levels didn’t generate useful data with no added prognostic value.Conclusion: Monitoring and follow-up of different hormones in patient’s serum in programmed frozen embryo transfer cycles didn’t have an impact on live birth, overall pregnancy & abortion rate when compared to ultrasound only in non-intervention group.
Limitations, reasons for caution
Patients in non-intervention group didn’t have a hormonal pre-transfer assessment so it’s not possible to determine if the progesterone levels are suboptimal or not when compared to intervention group.
Also, we didn’t have a post transfer hormonal assessment in case group to determine whether the progesterone dose reached desired levels.
Wider implications of the findings
Kofinas et al. proposed in his study that in order to optimize pregnancy and rate, P4 levels in FET cycles should be sustained between 10 and 20 ng/ml.
This was in accordance to our study where the cut off value of P4 on day of 11.83 ng/ml optimized pregnancy rates.

Abstract
The Agrobacterium-mediated floral dip protocol is the most extensively used transformation method for a model plant Arabidopsis thaliana. Several useful methods for Agrobacterium tumefaciens-mediated transformations of Arabidopsis are existing, but they are time consuming and with low transformation efficiency. Here, we developed a transgenic Arabidopsis lines TET12p::TET12-RFP in a short period of time and enhanced transformation efficiency by using a modified transformation method by applying drought stress after floral dip. In this protocol, Agrobacterium cells carrying TET12p::TET12-RFP recombinant vectors were resuspended in a solution of 5% sucrose, 0.05% (v/v) silwet L-77 to transform female gametes of developing Arabidopsis inflorescences. Treated Arabidopsis were then applied with different levels of drought stresses to stimulate plants for the utilization of maximum plant energy in seed maturation process. The applied stresses achieved the fast maturation of already treated inflorescences while stopped the growing of newly arising untreated inflorescence, thus decreased the chances of wrong collection of untransformed seeds. Consequently, the collected seeds were mostly transgenic with a transformation frequency of at least 10%, thus the screening for positive transformants selection was more advantageous on a selective medium as compared to a classical floral dip method. Within 2-3 months, two hundred of individual transgenic plants were produced from just 10 infiltrated plants. This study concludes that application of drought stresses in a specific stage of plant is a beneficial strategy for achieving the transgenic Arabidopsis in a short period of time with high transformation efficiency.

Abstract
BACKGROUND From April to June 2019, a total of 909 new HIV infections were identified in Larkana, Pakistan; 86% was children younger than 15 years. To identify the possible transmission links in this outbreak, a case-control study was conducted in June 2019. METHODS For cases, we selected a systematic random sample of 100 HIV-positive children from the screening list. We chose 2 age-matched and sex-matched controls from the neighborhood of each HIV-positive case. All selected children were tested using the World Health Organization-approved rapid diagnosis test algorithm. We interviewed the parents of each selected child about previous exposures to parenteral treatment and compared exposures of case and control children using conditional logistic regression. RESULTS The ages of the selected children ranged from 1 month to 10 years. More than 90% of both HIV+ and HIV- children had received outpatient health care from MBBS-qualified private physicians. Eighty-three percent of HIV+ children versus 46% of HIV- children had received health care from one private physician [adjusted odds ratio (aOR) = 29, 95% confidence interval (95% CI): 10 to 79]. Intravenous infusions during the last outpatient visit were reported by 29% of case versus 7% of controls (aOR 57, 95% CI: 2.9 to >1000), whereas no case children and 17% of control children had received only intramuscular injections (aOR 0, 95% CI: 0 to 41). Among cases, 94% had been given infusions through a drip set compared with 85% of control children (aOR = 7.7, 95% CI: 2.3 to 26). Infusions had been administered with reused IV drip sets in 70% of cases compared with 8% of controls (aOR = 197, 95% CI: 16 to 2400). DISCUSSION Private physicians reusing intravenous drip sets to treat outpatients seen in private practice were responsible for this HIV epidemic. Mapping and regulation of private practitioners were suggested.

Abstract
Introduction/Objective
The identification of plasmacytoid cells on rapid assessment leads to a wide range of differential diagnoses.
Methods/Case Report
We present a 51-year-old female with a parotid mass and cervical lymphadenopathy. The fine needle aspiration biopsy of the lymph node showed clusters of plasmacytoid cells. Flow cytometric studies showed cells positive for CD19, CD45, CD138 and kappa, but negative for CD38 and lambda. The kappa to lambda ratio was greater than 100. Histological sections showed plasmacytoid cells that were positive for AE1/AE3, S100, and SOX10, weakly positive for CK7 and GATA3, but negative for CD79a, CD45, EMA, p40, p63, and pan-melanoma markers. Kappa and lambda had a 1:1 ratio. Due to the discrepancy between the flow cytometric results and the immunohistochemistry, excision was recommended. The subsequent excision specimen showed classic morphology for myoepithelial carcinoma, plasmacytoid variant.
Results (if a Case Study enter NA)
NA
Conclusion
Myoepithelial carcinomas of the salivary glands are rare neoplasms, and they have various morphologies. The plasmacytoid variant can pose as a diagnostic pitfall. In fine needle aspiration biopsies, carcinoma cells with plasmacytoid morphology can be confused with a plasma cell neoplasm. CD138 is nonspecific marker, and it can be expressed in plasma cells as well as carcinomas. To further complicate matters, pancytokeratin and SOX10 can aberrantly expressed in some plasma cell myelomas. Flow cytometry studies is a valuable tool to define various cell types. However, it can be misleading if it is used as a sole source for interpreting plasmacytoid cells. Epithelial and myoepithelial neoplasms should be considered as differential diagnoses when CD138-positive plasmacytoid cells are encountered. Extended immunohistochemistry panel including multiple epithelial and myoepithelial markers play pivotal role in settling the diagnosis.

Abstract
Background Due to the current Coronavirus Disease 2019 (COVID-19) pandemic, there is a realization for innovation in procedures and protocols to minimize hospital stay and at the same time ensure continued evidence-based treatment delivered to the patients. We present a same-day discharge protocol for transcatheter mitral valve repair (TMVR) using MitraClip under general anaesthesia in a six-patient case series. This protocol aims to reduce the length of hospital stay, thereby minimizing potential for nosocomial COVID-19 infections and to promote safe discharge with cautious follow-up. Case summary Six patients with severe symptomatic mitral valve (MV) regurgitation underwent successful transfemoral MV repair using standard procedures. Following repair, patients were monitored on telemetry in the recovery area for 3 h, ambulated to assess vascular access stability and underwent post-procedural transthoracic echocardiogram to assess for any pericardial effusion or post-procedural prosthetic mitral stenosis. Conclusion Same-day discharge after TMVR is possible when done cautiously with close follow-up, can minimize hospital stay, improve resource utilization, and reduce risk of nosocomial COVID-19 infection.

Abstract
Honey is a suitable matrix for the evaluation of environmental contaminants including organochlorine insecticides. The present study was conducted to evaluate residues of fifteen organochlorine insecticides in honey samples of unifloral and multifloral origins from Dir, Pakistan. Honey samples (5 g each) were extracted with GC grade organic solvents and then subjected to Rotary Evaporator till dryness. The extracts were then mixed with n-Hexane (5 ml) and purified through Column Chromatography. Purified extracts (1μl each) were processed through Gas Chromatograph coupled with Electron Capture Detector (GC-ECD) for identification and quantification of the insecticides. Of the 15 insecticides tested, 46.7% were detected while 53.3% were not detected in the honey samples. Heptachlor was the most prevalent insecticide with a mean level of 0.0018 mg/kg detected in 80% of the samples followed by β-HCH with a mean level of 0.0016 mg/kg detected in 71.4% of the honey samples. Honey samples from Acacia modesta Wall. were 100% positive for Heptachlor with a mean level of 0.0048 mg/kg followed by β-HCH with a mean level of 0.003 mg/kg and frequency of 83.3%. Minimum levels of the tested insecticides were detected in the unifloral honey from Ziziphus jujuba Mill. Methoxychlor, Endosulfan, Endrin and metabolites of DDT were not detected in the studied honey samples. Some of the tested insecticides are banned in Pakistan but are still detected in honey samples indicating their use in the study area. The detected levels of all insecticides were below the Maximum Residue Levels (MRLs) and safe for consumers. However, the levels detected can cause mortality in insect fauna. The use of banned insecticides is one of the main factors responsible for the declining populations of important insect pollinators including honeybees.

Abstract
We investigate the magnetic properties of amorphous Sm10Co90/Co60(Al70Zr30)40/Co85(Al70Zr30)15exchange-spring magnet trilayers. The magnetically soft Co85(Al70Zr30)15layer is coupled to the magnetically hard Sm10Co90layer through the weakly magnetic low-TcCo60(Al70Zr30)40spacer layer. The strength of the coupling can be controlled with temperature and the coupling persists above the intrinsicTcof the spacer layer due to a long-range magnetic proximity effect. Polarized neutron reflectivity is used to examine the magnetic profile of the trilayers during magnetization reversal. A two-step switching occurs, with the switching angle of the soft layer strongly dependent on the strength of the coupling. In the strong coupling regime a magnetic state can be achieved where the soft layer magnetization is perpendicular to the hard layer whereas in the weak coupling regime the soft layer reverses fully.

Abstract
The supraclavicular artery flap is used for reconstruction of defects of the head and neck. One of the major implications of this procedure is injury to the nerve roots of C3 and C4 of the superficial cervical plexus, which provides sensation over the clavicle, shoulder and proximal chest, thereby causing problems in overall shoulder function. The objective of this study was to assess shoulder function, range of motion, pain, daily activities and overall satisfaction of the patient after using this flap. This study was conducted at the Department of Plastic & Reconstructive Surgery, Dow University of Health Sciences & Dr. Ruth KM Pfau Civil Hospital Karachi, Pakistan, from May 2015 to November 2018. Supraclavicular flap was used in 35 patients who underwent soft tissue reconstruction of defect of the neck after release of post burn contracture. Penn Shoulder Score and Constant Murley Score were used as assessment tools. Assessment by Penn Shoulder Score resulted in 25 (71.4%) patients within the upper quartile and 10 (18.6%) patients within the lower quartile. Constant Murley Score showed 19 (54.2%) of patients had 161°-180° shoulder abduction and lateral elevation. Forward flexion of 161°-180° was seen in 17 (48.5%) patients, 17 (48.5%) had internal rotation till the inter scapular region, 15 (42.8%) had no impairment of external rotation, 19 (54.2%) patients had no impairment of work/recreation, 25 (71.4%) had felt no change in their sleep and 22 (62.8%) were able to position their arm above their head. Overall parameters indicate better function, good range of motion, less pain, resumption of daily activities, and overall satisfaction.

Abstract
Simple tuneup of fast two-qubit gates is essential for the scaling of quantum processors. We introduce the sudden variant (SNZ) of the net zero scheme realizing controlled-Z (CZ) gates by flux control of transmon frequency. SNZ CZ gates realized in a multitransmon processor operate at the speed limit of transverse coupling between computational and noncomputational states by maximizing intermediate leakage. Beyond speed, the key advantage of SNZ is tuneup simplicity, owing to the regular structure of conditional phase and leakage as a function of two control parameters. SNZ is compatible with scalable schemes for quantum error correction and adaptable to generalized conditional-phase gates useful in intermediate-scale applications.

Abstract
OBJECTIVE In current study we performed sequencing of palm domain of HCV-NS5B gene, its ancestral analysis along with amino acids substitution analysis. These analysis were done to find the molecular basis of the viral resistance against Sofosbuvir drug. METHODS Blood samples from individuals with chronic Hepatitis C infection that were resistant to Sofosbuvir were collected. The samples were processed for their molecular characterization that included RNA extraction, Complementary DNA (cDNA) synthesize, nested PCR, gel elution, Sequencing, ancestral and 3D structure analysis. RESULTS Evolutionary analysis revealed that current study sequences (QAU-01, QAU-02) clustered with a previously studied sequence, KY971494.1. Moreover, we reports multiple novel amino acid substitutions in the palm domain of NS5B gene such as Ile116Val, Asn117Gly, Glu246Ala, Val252Ala, Glu258Gln, Cys262Leu, Ser269Arg, Ala272Thr, Ile293Leu, Lys304Arg, Asn307Gly, Ala338Val and Arg345Gly in our query sequence (QAU-01). At 246 and 269 position in (QAU-02), no substitution was observed. CONCLUSIONS We have noticed that the current sequences are relatively emerging and could have been originated from aforementioned sequence recently. Based on the current results, we suggests that these substitutions could be associated with structural or functional impairment of protein and could also be may be considered as resistance associated substitutions (RAS) to Sofosbuvir drug.

Abstract
In the absence of robust testing programs, timely and detailed outbreak reporting is essential for HIV control. Unsafe injection practices and injection drug use have been linked to multiple HIV outbreaks in Pakistan since 2003; however, few studies have systematically analyzed the causes of these outbreaks. We conducted a systematic review of published English-language literature indexed in bibliographic databases and search engines and a focused gray literature review to collate and analyze all reported HIV outbreaks in Pakistan during 2000–2019. Of 774 unique publications reviewed, we identified 25 eligible publications describing 7 outbreaks. More than half occurred during 2016–2019. The primary sources of transmission were iatrogenic transmission, affecting children, persons with chronic medical conditions, and the general population (4 outbreaks); injection drug use (2 outbreaks); and a combination of both (1 outbreak). In the absence of robust HIV testing and surveillance in Pakistan, timely and detailed outbreak reporting is important to understand the epidemiology of HIV in the country.

Abstract
Background Effective halting of outbreaks in skilled nursing facilities (SNFs) depends on the earliest recognition of cases. We assessed confirmed COVID-19 cases at an SNF impacted by COVID-19 in the United States to identify early indications of COVID-19 infection. Methods We performed retrospective reviews of electronic health records for residents with laboratory-confirmed SARS-CoV-2 during February 28–March 16, 2020. Records were abstracted for comorbidities, signs and symptoms, and illness outcomes during the 2 weeks before and after the date of positive specimen collection. Relative risks (RRs) of hospitalization and death were calculated. Results Of the 118 residents tested among approximately 130 residents from Facility A during February 28–March 16, 2020, 101 (86%) were found to test positive for SARS-CoV-2. At initial presentation, about two-thirds of SARS-CoV-2–positive residents had an abnormal vital sign or change in oxygen status. Most (90.2%) symptomatic residents had elevated temperature, change in mental status, lethargy, change in oxygen status, or cough; 9 (11.0%) did not have fever, cough, or shortness of breath during their clinical course. Those with change in oxygen status had an increased relative risk (RR) of 30-day mortality [51.1% vs 29.7%, RR 1.7, 95% confidence interval (CI) 1.0–3.0]. RR of hospitalization was higher for residents with underlying hepatic disease (1.6, 95% CI 1.1–2.2) or obesity (1.5, 95% CI 1.1–2.1); RR of death was not statistically significant. Conclusions and Implications Our findings reinforce the critical role that monitoring of signs and symptoms can have in identifying COVID-19 cases early. SNFs should ensure they have a systematic approach for responding to abnormal vital signs and oxygen saturation and consider ensuring common signs and symptoms identified in Facility A are among those they monitor.

Abstract
Background The coronavirus disease 2019 (COVID-19) pandemic has resulted in drastic changes to the practice of medicine, requiring healthcare systems to find solutions to reduce the risk of infection. Using a case series, we propose a protocol for same-day discharge (SDD) for selected patients undergoing transcatheter aortic valve replacement (TAVR) using real-time remote cardiac monitoring. Six patients with severe symptomatic aortic stenosis underwent TAVR and were discharged on the same day. Case summary Six patients with symptomatic severe native or bioprosthetic aortic valve stenosis underwent a successful transfemoral TAVR using standard procedures, including the use of rapid atrial pacing to assess the need for permanent pacemaker implantation. Following TAVR, patients were monitored on telemetry in the recovery area for 3 h, ambulated to assess vascular access stability, and discharged with real-time remote cardiac monitoring if no new conduction abnormality was observed. The patients were seen by tele-visits within 2 days and 2 weeks after discharge. Discussion Amidst the COVID-19 pandemic, SDD following successful transfemoral TAVR may be feasible for selected patients and reduce potential COVID-19 exposure.

Abstract
Background For HIV-exposed infants in Malawi, there are missed opportunities at each step of the testing and treatment cascade. Objective This study assessed factors associated with HIV positivity among infants in Malawi and turn-around times for infant HIV testing. Methods HIV testing data for infants aged 0–18 months from 2012 to 2015 were extracted from the Malawi HIV laboratory information management system and analysed using logistic regression. Turn-around time was defined as time between collection of samples to results dispatch from the laboratory. Results A total of 106 997 tests were included in the analyses. A subset of 76 006 observations with complete dates were included in the turn-around time analysis. Overall positivity was 4.2%. Factors associated with positivity were increasing age (infants aged 3–6 months: adjusted odds ratio [aOR] = 2.24; infants aged 6–9 months: aOR = 3.42; infants aged > 9 months: aOR = 4.24), female sex (aOR = 1.08) and whether the mother was alive and not on antiretroviral therapy at time of the infant’s test (aOR = 1.57). Provision of HIV prophylaxis to the infant after birth (aOR = 0.38) was found to be protective against HIV positivity. The median turn-around time was 24 days (increased from 19 to 34 days between 2012 and 2015). Conclusion Infant HIV positivity has decreased in Malawi, whereas turn-around time has increased. Factors associated with positivity include increasing age, female sex, and whether the mother was alive and not on antiretroviral therapy at the time of the infant’s test.

In the United States, outbreaks of SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), were initially reported in densely populated urban areas (1); however, outbreaks have since been reported in rural communities (2,3). Rural residents might be at higher risk for severe COVID-19-associated illness because, on average, they are older, have higher prevalences of underlying medical conditions, and have more limited access to health care services.* In May, after a cluster of seven COVID-19 cases was identified in a rural Ohio Amish community, access to testing was increased. Among 30 additional residents tested by real-time reverse transcription-polymerase chain reaction (RT-PCR; TaqPath COVID-19 Combo Kit),† 23 (77%) received positive test results for SARS-CoV-2. Rapid and sustained transmission of SARS-CoV-2 was associated with multiple social gatherings. Informant interviews revealed that community members were concerned about having to follow critical mitigation strategies, including social distancing§ and mask wearing.¶ To help reduce the ongoing transmission risk in a community, state and county health department staff members and community leaders need to work together to develop, deliver, and promote culturally responsive health education messages to prevent SARS-CoV-2 transmission and ensure that access to testing services is timely and convenient. Understanding the dynamics of close-knit communities is crucial to reducing SARS-CoV-2 transmission.

Abstract
The pandemic of coronavirus disease 2019 (COVID-19) has disrupted immunization programs around the globe, potentially increasing life-threatening vaccine-preventable diseases. Pakistan and Afghanistan are the only countries, which are still struggling to eradicate wild poliovirus. All vaccination campaigns in Pakistan were suspended in April due to the COVID-19 outbreak, leading 40 million children to miss out on polio vaccination. Like the climate crisis, the COVID-19 pandemic could be regarded as a child-rights crisis because it could have life-threatening impact over children, who need immunization, now and in the long-term. Delays in polio vaccination programs might not have immediate impact but, in the long-term, the increase in polio cases in Pakistan could result in the global export of infections. Therefore, healthcare authorities must intensify their efforts to track and vaccinate unvaccinated children in countries like Pakistan and Afghanistan. Polio vaccination campaigns need to resume immediately, so we suggest applying social distancing measures along with standard operating procedure to flatten the transmission curve of COVID-19. Furthermore, the concurrent emergence of cVDPV2 means that tOPV should temporarily be used for primary immunization. In the current review, we have discussed delays in polio vaccination, surveillance of polio viruses, reported cases in Pakistan along with recommendations to overcome interrupted immunization.

Abstract
Abstract
Introduction
Recent epidemiologic data suggests increased risk of ischaemic stroke in cancer patients. The etiology of increased ischaemic stroke is unknown. Atrial fibrillation (AF) is among the potential etiologies. The risk of AF has not been studied among cancer patients in the United States.
Purpose
Ascertain the association of AF in cancer patients in the USA by using the largest database i.e. National Inpatient Sample (NIS).
Methods
Patients ≥18 years old were selected in the NIS database for years 2010 to 2014 and stratified based on presence or absence of any of four cancers (lung, colon, breast and prostate; 4CA) using ICD 9 codes. Atrial fibrillation and stroke/TIA were also identified using ICD 9 codes. Components of CHADS2 score (CHF, hypertension, Age>75, diabetes and stroke/TIA) were identified using ICD 9 codes. χ2 tests performed for prevalence of AF in patients with or without these cancers stratified by CHADS2 score. Binary logistic regression was used to analyze individual components of CHADS2 score.
Results
AF and stroke/TIA were significantly higher among 4CA than non-4CA group (18.7% vs 12.0%, P<0.001 and 5.4% vs 4.8%, P<0.001 respectively). AF prevalence increased with CHADS2 and was significantly higher in 4CA group with CHADS2 score 0 to 4 (Table 1 and Figure 1). Logistic regression for the outcome of AF showed “Age >75” OR (3.0), CHF (2.8), CVA (1.2), HTN (1.3) and DM (1.1).
Conclusion
This is the first study using a national database of USA patients to estimate prevalence of AF in cancer patients compared to non-cancer patients and reaffirms the higher burden of AF in cancer patients. Prevalence of both AF and stroke were greater in cancer patients when stratified by CHADS2 score. This may indicate not just an increased risk of AF but an increased risk of stroke/TIA for the same CHADS2 score. Stroke incidence was also higher in the 4CA group (5.4% vs. 4.8% P<0.001). Cancer patients with CHADS2 score >1 may benefit from screening with loop recorder to identify previously undetected AF and initiate anticoagulation therapy. Prospective longitudinal studies are needed to validate this retrospective study.
