Solving crimes with hypnosis.

Following a brief review of the literature on hypnosis and memory, this paper overviews the procedures that are used in conducting forensic hypnosis interviews. Ten forensic hypnosis cases are then described. These real world cases are in stark contrast to research done in an artificial laboratory setting where the information to be recalled lacks personal relevance and was not associated with emotionally arousing situations. These cases illustrate how forensic hypnosis can result in obtaining important additional investigative leads which lead to the solving of crimes.

Prognostic model for nephrotoxicity among HIV-positive Zambian adults receiving tenofovir disoproxil fumarate-based antiretroviral therapy.

Persons living with HIV (PLWH) receiving tenofovir disoproxil fumarate (TDF)-based antiretroviral therapy (ART) risk suffering TDF-associated nephrotoxicity (TDFAN). TDFAN can result in short- and long-term morbidity, including permanent loss of kidney function, chronic kidney disease (CKD), and end-stage kidney disease (ESKD) requiring dialysis. Currently, there is no model to predict this risk or discern which patients to initiate TDF-based therapy. Consequently, some patients suffer TDFAN within the first few months of initiating therapy before switching to another suitable antiretroviral or a lower dose of TDF. In a prospective observational cohort study of adult Zambian PLWH, we modelled the risk for TDFAN before initiating therapy to identify individuals at high risk for experiencing AKI after initiating TDF-based therapy. We enrolled 205 HIV-positive, ART-naïve adults initiating TDF-based therapy followed for a median of 3.4 months for TDFAN at the Adult Infectious Disease Research Centre (AIDC) in Lusaka, Zambia. We defined TDFAN as meeting any of these acute kidney disease (AKD) criteria: 1) An episode of estimated glomerular filtration rate (eGFR)< 60ml/ min/1.73m2 within 3 months, 2) reduced eGFR by> 35% within 3 months or 3) increased serum creatinine by> 50% within 3 months. A total of 45 participants (22%) developed acute kidney disease (AKD) after TDF-based therapy. The development of AKD within the first 3 months of commencing TDF-based therapy was associated with an increase in baseline serum creatinine, age, baseline eGFR and female sex. We concluded that baseline characteristics and baseline renal function biomarkers predicted the risk for AKD within the first 3-months of TDF-based therapy.

Design For The First Narrowband Filter For The Dark Energy Camera: Optimizing The LAGER Survey For Z ~ 7 Galaxies.

We present the design for the first narrowband filter NB964 for the Dark Energy Camera (DECam), which is operated on the 4m Blanco Telescope at the Cerro Tololo Inter-American Observatory. The NB964 filter profile is essentially defined by maximizing the power of searching for Lyman alpha emitting galaxies (LAEs) in the epoch of reionization, with the consideration of the night sky background in the near-infrared and the DECam quantum efficiency. The NB964 filter was manufactured by Materion in 2015. It has a central wavelength of 964.2 nm and a full width at half maximum (FWHM) of 9.2 nm. An NB964 survey named LAGER (Lyman Alpha Galaxies in the Epoch of Reionization) has been ongoing since December 2015. Here we report results of lab tests, on-site tests and observations with the NB964 filter. The excellent performances of this filter ensure that the LAGER project is able to detect LAEs at z ~ 7 with a high efficiency.

Higher Time-Updated Body Mass Index: Association With Improved CD4+ Cell Recovery on HIV Treatment.

BACKGROUND: Prior studies found overweight or obese HIV-infected individuals had greater early CD4 cell recovery on antiretroviral therapy (ART), but the results have been inconsistent. We assessed the longitudinal relationship between body mass index (BMI) and CD4 cell recovery on ART in a large, multisite cohort to identify potential physiologic links between adiposity and CD4 cell expansion. METHODS: We modeled the relationship of time-updated BMI with CD4 count in patients starting ART from 17 North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD) cohorts. The primary analysis used a linear mixed effects model incorporating up to 13 years of data per patient and adjusted for age, sex, race, ART regimen, baseline CD4 count and other covariates. Sensitivity analyses limited the cohort to patients with sustained viral suppression or censored at virologic failure. RESULTS: Fourteen thousand eighty-four HIV-infected individuals initiating ART contributed data between 1998 and 2010. Time-updated BMI was significantly associated with CD4 cell recovery over time (P < 0.001). After 5 years of ART, the mean CD4 count at a BMI of 30 kg/m was 22% higher than at a BMI of 22 kg/m (606 vs. 498 cells per microliter) and 34% higher at a BMI of 40 kg/m (665 vs. 498 cells per microliter). Results were similar in the sensitivity analyses. DISCUSSION: Higher BMI is associated with long-term advantages in immune recovery on ART. Although it is unclear if this impacts health outcomes, including balancing the negative health effects of obesity, elucidating the underlying mechanism could identify therapies for patients with suboptimal immune reconstitution.

HIV-1 subtype C drug-resistance background among ARV-naive adults in Botswana.

Current HIV-1 antiretroviral (ARV) drug resistance knowledge is limited to HIV-1 subtype B (HIV-1B). We addressed whether unique genetic and phenotypic properties of HIV-1 subtype C (HIV-1C), southern Africa's most prevalent subtype, may foment earlier and/or distinct resistance mutations. Population-level HIV-1C genotypes were evaluated with respect to drug resistance prevalence before Botswana's public ARV treatment programme began. Viruses were genotyped from 11 representative districts of northern and southern Botswana, and consensus sequences from these 71 individuals and 51 previously reported sequences from HIV-positive blood donors were constructed. Phylogenetic analysis classified all 71 sequences but one, which exhibited pol gene mosaicism, as HIV-1C. The protease and reverse transcriptase coding region had no detectable known primary mutations associated with HIV-1B protease inhibitor (PI) drug resistance. Secondary mutations associated with PI drug resistance were found in all sequences. Several HIV-1C-specific polymorphic sites were found across the pol gene. Northern and southern Botswana viral sequences showed no significant differences from each other. Population genotyping shows that, without countrywide ARV treatment, HIV-1C-infected Batswana harbour virtually no primary mutations known to confer resistance to the three major HIV-1B ARV drug classes. Some secondary PI mutations and polymorphic sites in the protease enzyme necessitate continuous population monitoring, particularly after introduction of countrywide ARV treatment in Botswana. Although its PI resistance development rate and kinetics are not known, our data may suggest increased susceptibility and readiness of HIV-1C to develop resistance under drug pressure when the PI class of drugs is used.

Problems in the therapy for imported malaria in the United States.

BACKGROUND: Errors in the diagnosis of imported malaria are increasingly recognized. However, there are few data on the treatment of malaria in the United States. METHODS: Medical records were reviewed for 83 patients with microscopically confirmed malaria at Cook County Hospital, Chicago, Ill, between 1991 and 1999. RESULTS: Errors in drug treatment occurred in 25% of patients in this study. The most common error in therapy was the failure to prescribe primaquine to eradicate the liver forms of Plasmodium vivax. Another 5 patients with P vivax received an inappropriate drug regimen. Errors in Plasmodium falciparum therapy occurred in 5 patients. All patients received an inappropriate drug regimen. While the clinical symptoms and signs do not help distinguish the infecting Plasmodium species, the travel history is extremely helpful in guiding drug selection. Non-infectious diseases specialists are more likely to make errors in therapy than are infectious diseases specialists. CONCLUSIONS: Despite widely published guidelines on the treatment of malaria, there are frequent errors in the therapy for malaria. A detailed travel history emphasizing the duration and country of travel should be sought. Primaquine should be included in the primary prescription for the treatment of P vivax infection. Improvements in the therapy for malaria can be made with the aid of an infectious diseases specialist and/or a tropical medicine specialist.

Immunodeficiency at antiretroviral therapy start: five-Year adult data (2012-2017) based on evolving national policies in rural mozambique

Before the 2015 implementation of "Test and Start," the initiation of combination antiretroviral therapy (ART) was guided by specific CD4 cell count thresholds. As scale-up efforts progress, the prevalence of advanced HIV disease at ART initiation is expected to decline. We analyzed the temporal trends in the median CD4 cell counts among adults initiating ART and described factors associated with initiating ART with severe immunodeficiency in Zambézia Province, Mozambique. We included all HIV-positive, treatment-naive adults (age ≥ 15 years) who initiated ART at a Friends in Global Health (FGH)-supported health facility between September 2012 and September 2017. Quantile regression and multivariable logistic regression models were applied to ascertain the median change in CD4 cell count and odds of initiating ART with severe immunodeficiency, respectively. A total of 68,332 patients were included in the analyses. The median change in CD4 cell count under "Test and Start" was higher at +68 cells/mm3 (95% CI: 57.5-78.4) compared with older policies. Younger age and female sex (particularly those pregnant/lactating) were associated with higher median CD4 cell counts at ART initiation. Male sex, advanced age, WHO Stage 4 disease, and referrals to the health facility through inpatient provider-initiated testing and counseling (PITC) were associated with higher odds of initiating ART with severe immunodeficiency. Although there were reassuring trends in increasing median CD4 cell counts with ART initiation, ongoing efforts are needed that target universal HIV testing to ensure the early initiation of ART in men and older patients.

Mutations and polymorphisms associated with antiretroviral drugs in HIV-1C-infected African patients.

To detect and characterize polymerase gene (pol) polymorphisms and mutation patterns in HIV-1C-infected Batswana patients treated with reverse transcriptase inhibitors, samples from AIDS patients treated with highly active antiretroviral therapy (HAART) were sequenced for the region encompassing the entire HIV-1 protease (PR) and the first 335 amino acids of reverse transcriptase (RT). Amongst the 16 patients treated with antiretroviral (ARV) drugs, eight started HAART regimens containing didanosine, stavudine and nevirapine (ddI/d4T/NVP) or efavirenz (EFV) (arm A) while the others started with zidovudine (AZT) and lamivudine (3TC) given together as combivir (CBV) with either NVP or EFV as arm B. Arm B is the first line regimen currently provided by the Botswana ARV national programme. Greater efficacy, in terms of treatment duration, was observed in patients in arm B (14 months) as compared with patients in arm A (9 months); P<0.05, n=8. Appearance of the M184V mutation in the arm B patients coincided with a rebound of viral load (VL) (4.3 +/-0.1 log10 RNA copies/ml) and a significantly improved immunological parameter (deltaCD4=207.0+/-48.1 cells/microl; P<0.05). Interestingly, patients developing the M184V mutation preferentially harboured polymorphisms Q174K and/or I178L located in close proximity to pol position 184. The M184V mutation occurred following a clear clinical benefit consisting of increased CD4 cell counts and lower plasma viral loads. Primary mutations known to be associated with NNRTI and NRTI resistance for HIV-1B were observed in 10 of the 16 treated patients.
