Treatment Patterns and Clinical Outcomes in Patients with Hodgkin Lymphoma from Saudi Arabia, Türkiye, and South Africa: Subgroup Analysis from the International Multicenter Retrospective B-HOLISTIC Study.

Objective: B-HOLISTIC was a real-world retrospective study of treatment patterns and clinical outcomes in Hodgkin lymphoma (HL) in regions outside Europe and North America. This subgroup analysis reports findings from Saudi Arabia, Türkiye, and South Africa.

Materials And Methods: Patients aged ≥18 years and diagnosed with stage IIB-IV classical HL receiving frontline chemotherapy (frontline cHL) and/or with relapsed/refractory HL (RRHL) from January 2010 to December 2013 were assessed.

Haematopoietic stem-cell transplantation in an HIV endemic area: time to consider donors exposed to or living with HIV.

South Africa has more than 8 million people living with HIV. However, the number of patients undergoing haematopoietic stem-cell transplantation (HSCT) in South Africa is far below the target number. Donor numbers are insufficient to meet demand.

Treatment pathways and clinical outcomes in Hodgkin lymphoma outside Europe and North America: results from the international, multicenter, retrospective, B-HOLISTIC study.

Information on Hodgkin lymphoma (HL) is mostly limited to Europe and North America. This real-world, retrospective study assessed treatment pathways and clinical outcomes in adults with stage IIB-IV classical HL receiving frontline treatment ( = 1598) or relapsed/refractory HL (RRHL,  = 426) in regions outside Europe and North America between January 2010 and December 2013. The primary endpoint was progression-free survival (PFS) in the RRHL group.

Thymoma-associated multiorgan autoimmunity with exclusive gastrointestinal tract involvement: case report and review of the literature.

Thymoma-associated multiorgan autoimmunity (TAMA) is a recently delineated and rare paraneoplastic syndrome reported in patients with thymoma. The disorder is characterized by graft-versus-host disease-like pathology affecting the skin, gastrointestinal tract (GIT), and liver, and is usually associated with a poor outcome. We document a case of TAMA with exclusive GIT involvement which included the stomach, small and large bowel, presenting in a 66-year-old male patient 5 years after complete resection of a type B2 thymoma.

Transient clinical improvement of a mitochondrial neurogastrointestinal encephalomyopathy-like syndrome after allogeneic haematopoietic stem cell transplantation.

Mitochondrial neurogastrointestinal encephalopathy (MNGIE), usually an autosomal-recessive inherited condition, causes gastrointestinal dysmotility, ophthalmoplegia, ptosis, leukoencephalopathy and neuropathy. The chromosome 22 disorder, due to mutations in the nuclear gene TYMP encoding thymidine phosphorylase (TP), leads to the accumulation of thymidine and deoxyuridine, with mitochondrial dysfunction.This report describes a patient with an MNGIE-like syndrome with a heterozygous TYMP mutation who showed marked, but transient improvement postallogeneic haematopoietic stem cell transplantation (HSCT).

Antibody and Viral Nucleic Acid Testing of Serum and Cerebrospinal Fluid for Diagnosis of Eastern Equine Encephalitis.

Eastern equine encephalitis diagnostic serum antibody can appear 6 days after the onset of symptoms, and its numbers can increase 4-fold in 4 days, arguing for early and frequent serum testing. In populations where cerebrospinal fluid viral nucleic acid testing sensitivity and specificity remain undetermined, cerebrospinal antibody testing should also be performed.

Competing S(N)2 and E2 reaction pathways for hexachlorocyclohexane degradation in the gas phase, solution and enzymes.

Quantum chemistry calculations have been used alongside experimental kinetic analysis to investigate the competition between S(N)2 and E2 mechanisms for the dechlorination of hexachlorocyclohexane isomers, revealing that enzyme specificity reflects the intrinsic reactivity of the various isomers.

The role of exchange in systematic DFT errors for some organic reactions.

Serious (up to 87 kJ mol(-1)) systematic DFT errors in a series of isodesmic reactions are found to be due to the DFT exchange component, and can be largely corrected by substitution of the DFT exchange energy with the Fock exchange energy.

Should contemporary density functional theory methods be used to study the thermodynamics of radical reactions?

The performance of a variety of DFT functionals (BLYP, PBE, B3LYP, B3P86, KMLYP, B1B95, MPWPW91, MPW1B95, BB1K, MPW1K, MPWB1K, and BMK), together with the ab initio methods RHF, RMP2, and G3(MP2)-RAD, and with ONIOM methods based on combinations of these procedures, is examined for calculating the enthalpies of a range of radical reactions. The systems studied include the bond dissociation energies (BDEs) of R-X (R = CH3, CH2F, CH2OH, CH2CN, CH2Ph, CH(CH3)Ph, C(CH3)2Ph; X = H, CH3, OCH3, OH, F), RCH(Ph)-X (R = CH3, CH3CH2, CH(CH3)2, C(CH3)3, CH2F, CH2OH, CH2CN; X = H, F), R-TEMPO (R = CH3, CH2CH3, CH(CH3)2, C(CH3)3, CH2CH2CH3, CH2F, CH2OH, CH2CN, CH(CN)CH3, CH(Cl)CH3; TEMPO = 2,2,6,6,-tetramethylpiperidin-1-yloxyl) and HM1M2-X (M1, M2 = CH2CH(CH3), CH2CH(COOCH3), CH2C(CH3)(COOCH3); X = Cl, Br), the beta-scission energies of RXCH2* and RCH2CHPh* (R = CH3, CH2CH3, CH(CH3)2, C(CH3)3; X = O, S, CH2), and the enthalpies of several radical addition, ring-opening, and hydrogen- and chlorine-transfer reactions. All of the DFT methods examined failed to provide an accurate description of the energetics of the radical reactions when compared with benchmark G3(MP2)-RAD values, with all methods tested showing unpredictable deviations of up to 40 kJ mol-1 or more in some cases.

Discovery and optimization of a series of carbazole ureas as NPY5 antagonists for the treatment of obesity.

The hypothesis that antagonists of the neuropeptide Y5 receptor would provide safe and effective appetite suppressants for the treatment of obesity has prompted vigorous research to identify suitable compounds. We discovered a series of acylated aminocarbazole derivatives (e.g.

Development of variable-number tandem repeat typing of Mycobacterium bovis: comparison of results with those obtained by using existing exact tandem repeats and spoligotyping.

Various genetic markers have been exploited for fingerprinting the Mycobacterium tuberculosis complex (MTBC) in molecular epidemiological studies, mainly through identifying restriction fragment length polymorphisms (RFLP). In large-scale studies, RFLP typing has practical processing and analysis limitations; therefore, attempts have been made to move towards PCR-based typing techniques. Spoligotyping (spacer oligotyping) and, more recently, variable-number tandem repeat (VNTR) typing have provided PCR-derived typing techniques.

Discrimination of Mycobacterium tuberculosis complex bacteria using novel VNTR-PCR targets.

The lack of a convenient high-resolution strain-typing method has hampered the application of molecular epidemiology to the surveillance of bacteria of the Mycobacterium tuberculosis complex, particularly the monitoring of strains of Mycobacterium bovis. With the recent availability of genome sequences for strains of the M. tuberculosis complex, novel PCR-based M.
