On the Dark Side in Al Doura – A Soldier in the Shadow

leave a comment »

If any a story of PTSD was tragic, this one is: “U.S. Army Ranger John Needham, who was awarded two purple hearts and three medals for heroism, wrote to military authorities in 2007 reporting war crimes that he witnessed being committed by his own command and fellow soldiers in Al Doura, Iraq. His charges were supported by atrocity photos which, in the public interest, are now released in this video. John paid a terrible price for his opposition to these acts. His story is tragic. ” Credits to Cindy Piester

what I read, and what I don’t – Sunday, January 13 2008

On Wednesday, Jan. 16 2008, I read, that a man who pleaded guilty Tuesday to ripping the head off a duck in the lobby of a St. Paul, Minn., hotel is not a horrible person. His attorney said: “He’s really a nice young man, he’s humble, he’s hard-working, he was a good student and worked hard to get the job he did,” said attorney Michael Colich. “Nobody’s been willing to look at what good things he’s done in his life and what good things he’ll do in his life.”

Ramsey County District Judge Margaret Marrina said it appeared Clark, 26, had “a substantial amount to drink” before the incident. He will be sentenced next month, the newspaper reported. Although attorney and the prosecution agreed on a sentence — no more than 45 days in jail, two years of probation, 40 hours of community service, a $500 fine, restitution and no pet ownership for two years [sic] — the judge will decide.

On Sunday, Jan. 13, 2008, I read, that “violence is a leading cause of death for Iraqi adults and was the main cause of death in men between the ages of 15 and 59 years during the first 3 years after the 2003 invasion.Although the estimated range is substantially lower than a recent survey-based estimate, it nonetheless points to a massive death toll, only one of the many health and human consequences of an ongoing humanitarian crisis.”

A large national household survey conducted by the Iraqi government and WHO estimates that 151 000 Iraqis died from violence between March 2003 and June 2006.

The study found that on average 128 Iraqis per day died of violent causes in the first year following the invasion and that the average daily violent death toll was 115 in the second year and 126 in the third year. More than half of the violent deaths occurred in Baghdad.

nota bene: “Some homes could not be visited because of high levels of insecurity and more people move residence in times of conflict. These factors were taken into account in the analysis as they may affect the accuracy of the survey work,” said Salih Mahdi Motlab Al-Hasanawi, Minister of Health of Iraq. “Nonetheless, the survey results indicate a massive death toll since the beginning of the conflict.”

That makes a cruel arithmetical average of  123,33 Iraqui lives per day for the first three years of what U.S. President George Bush called a job for US troops to render Iraq democratic and stable.

What I don’t read is,  that any judge were to decide, how many days in jail, how many years of probation, how many hours of community service, how big a fine, restitution a human life in Iraq is worth. And who of the Bush administration is going to be sentenced…

Low Platelet Count – High Risk Of HIV-related Dementia

with one comment

HIV patients with declining platelet counts appear to be at increased risk for HIV–associated dementia.

“Human immunodeficiency virus–associated dementia (HIV-D) is a syndrome encompassing a spectrum of cognitive, behavioral and motor deficits that usually has an insidious onset and a chronic progressive course,” the authors write as background information in the article. Therapies leading to longer life for HIV patients have paradoxically increased the prevalence of this condition. Identifying biological markers for the development of HIV–associated dementia is critical both for diagnosing the disorder and for understanding its underlying mechanisms.

Lynn M. Wachtman, D.V.M., M.P.H., of Bloomberg School of Public Health, The Johns Hopkins University School of Medicine, Baltimore, and colleagues studied 396 patients with advanced HIV who were recruited for this prospective study between 1998 and 2003. Participants were examined every six months and completed mental and physical evaluations.

Blood samples were also collected and assessed for platelet count (the number of clotting cells in the blood), hemoglobin levels, CD4 lymphocyte count (a measure of certain types of white blood cells, which reflects the state of the immune system) and plasma HIV RNA levels (which indicate the amount of “viral load,” and predict HIV progression).

After a median (midpoint) follow-up of 31.1 months, 40 participants developed HIV–associated dementia. A decline in platelet count from baseline was associated with the development of dementia within six to 12 months. “Those HIV-infected individuals with a decline in platelets from baseline values at this lagged time point had a two-fold increased risk of dementia” in several different analyses, the authors write. The specific timing of the association indicates that the levels of circulating platelets fluctuate as HIV–associated dementia develops, they note.

“Further analyses indicated that decline from baseline platelet levels was associated with a five- to six-fold increased risk of dementia during the first two years of follow-up, but it was not associated with an increased risk of dementia after two years,” the authors continue. “It is possible that individuals who do not progress rapidly to neurologic compromise differ in respect to immune activation, treatment adherence or virologic control relative to those who develop dementia more rapidly.”

“Because CD4 cell counts and HIV RNA levels have proven not to be predictive of HIV–associated dementia, it is important to investigate alternative serum and hematologic markers,” the authors conclude. “Should these markers be routinely measured in a clinical setting, such as platelet counts, they may prove useful for patient management. This study identifies a significant association between platelet decline and incident HIV–associated dementia.” Further study of platelet levels during HIV–associated dementia may lead both to a specific marker for the development of HIV–associated dementia and a better understanding of how the disease develops.

BACKGROUND: The identification of biomarkers identifying onset of human immunodeficiency virus-associated dementia (HIV-D) is critical for diagnosis and the elucidation of pathophysiologic pathways. OBJECTIVE: To examine the association between platelet decline from baseline and HIV-D. DESIGN: Prospective cohort study within the North-East AIDS Dementia cohort. SETTING: Four participating referral centers in the United States. PARTICIPANTS: A total of 396 subjects with advanced human immunodeficiency virus (HIV) infection recruited between 1998 and 2003 and undergoing serial neurologic assessments. Eligibility criteria required CD4 cell counts less than 200/muL or less than 300/muL with evidence of cognitive impairment. A cohort subset without prevalent HIV-D at baseline and without incident HIV-D at the visit immediately after baseline was analyzed (n = 146). Main Outcome Measure Time to first diagnosis of HIV-D. RESULTS: After a median follow-up of 31.1 months, 40 subjects developed HIV-D. Platelet decline from baseline was associated with the development of HIV-D when examined as a time-dependent variable lagged by 6 to 12 months before outcome (multivariate hazard ratio [HR], 2.39; 95% confidence interval [CI], 1.14-5.02; P = .02). This association was stronger during the first 2 years of follow-up (multivariate HR, 6.76; 95% CI, 2.36-19.41; P < .001) than during later years (multivariate HR, 0.94; 95% CI, 0.33-2.67; P = .90). CONCLUSIONS: These results suggest that individuals with declining platelet counts are at greater risk for HIV-D and that the dynamics of circulating platelets vary with respect to the temporal progression of HIV-D. This highlights an avenue to be explored in the understanding of HIV-D pathogenesis.
