Importance of testing the internal consistency and construct validity of the Pittsburgh Sleep Quality Index (PSQI) in study groups of day and night shift workers: Example of a sample of long-haul truck drivers in South Africa.

Johanna Roche, Alinda G Vos, Samanta T Lalla-Edward, Peter R Kamerman, Wd Francois Venter, Karine Scheuermaier,

Irregular work times promote inconsistent completion of the Pittsburgh Sleep Quality Index (PSQI) among shift workers. We aimed to demonstrate the importance of testing the internal consistency and construct validity of the PSQI and of the Epworth Sleepiness Scale (ESS) by presenting the methodology in a sample of long-haul truckers ...

Greater baseline pain inclusion criteria in clinical trials increases regression to the mean effect: a modelling study.

Peter R Kamerman, Jan Vollert,

<h4>Abstract</h4>We modelled the effects of pain intensity inclusion thresholds (3/10, 4/10, and 5/10 on a 0 to 10 point numerical pain rating scale) on the magnitude of the regression to the mean effect under conditions that were consistent with the sample mean and variance, and inter-measurement correlation observed in clinical ...

High individual pain variability in people living with HIV: A graphical analysis.

Antonia Louise Wadley, Willem D F Venter, Michelle Moorhouse, Godspower Akpomiemie, Celicia Serenata, Andrew Hill, Simiso Sokhela, Noxolo Mqamelo, Peter R Kamerman,

<h4>Background</h4>People living with HIV (PLWH) frequently experience pain. Following calls to analyse individual-level data in addition to group-level data in pain studies, we compared individual and group-level changes in pain prevalence, intensity and number of pain sites over 48 weeks in a large cohort of PLWH. This is the largest ever ... Read more >>

Peter R Kamerman, Debbie Bradshaw, Ria Laubscher, Victoria Pillay-van Wyk, Glenda E Gray, Duncan Mitchell, Sean Chetty,

Limited information on the prevalence and risk factors for chronic pain is available for developing countries. Therefore, we investigated the prevalence of chronic pain and the association between this pain and various personal and sociodemographic factors by including questions in the South Africa Demographic and Household Survey 2016. The survey ... Read more >>

A systematic review of experimental methods to manipulate secondary hyperalgesia in humans: protocol.

Victoria J Madden, Gillian J Bedwell, Prince C Chikezie, Andrew S C Rice, Peter R Kamerman,

<h4>Background</h4>Neuropathic pain affects 7-10% of people, but responds poorly to pharmacotherapy, indicating a need for better treatments. Mechanistic research on neuropathic pain frequently uses human surrogate models of the secondary hyperalgesia that is a common feature of neuropathic pain. Experimentally induced secondary hyperalgesia has been manipulated with pharmacological and non-pharmacological ... Read more >>

Nanna B Finnerup, Simon Haroutounian, Ralf Baron, Robert H Dworkin, Ian Gilron, Maija Haanpaa, Troels S Jensen, Peter R Kamerman, Ewan McNicol, Andrew Moore, Srinivasa N Raja, Niels T Andersen, Emily S Sena, Blair H Smith, Andrew S C Rice, Nadine Attal,

Multiple recent pharmacological clinical trials in neuropathic pain have failed to show beneficial effect of drugs with previously demonstrated efficacy, and estimates of drug efficacy seems to have decreased with accumulation of newer trials. However, this has not been systematically assessed. Here, we analyze time-dependent changes in estimated treatment effect ... Read more >>

Was That Painful or Nonpainful? The Sensation and Pain Rating Scale Performs Well in the Experimental Context.

Victoria J Madden, Peter R Kamerman, Valeria Bellan, Mark J Catley, Leslie N Russek, Danny Camfferman, G Lorimer Moseley,

In experiments on pain, participants are frequently exposed to nonpainful and painful stimuli; however, the conventional pain-rating scales lack a nonpainful range and a clear point of transition from nonpainful to painful events. The Sensation and Pain Rating Scale (SPARS) assesses the full stimulus intensity range, extending from no sensation ... Read more >>

Psychological Factors Associated With Painful Versus Non-Painful HIV-Associated Sensory Neuropathy.

Prinisha Pillay, Antonia L Wadley, Catherine L Cherry, Alan S Karstaedt, Peter R Kamerman,

HIV-associated sensory neuropathy (HIV-SN) is a common, and frequently painful complication of HIV, but factors that determine the presence of pain are unresolved. We investigated: (i) if psychological factors associated with painful (n = 125) versus non-painful HIV-SN (n = 72), and (ii) if pain and psychological factors affected quality of life (QoL). We ...

HIV-associated sensory peripheral neuropathy (HIV-SN) afflicts approximately 50% of patients on antiretroviral therapy, and is associated with significant neuropathic pain. Simple accurate diagnostic instruments are required for clinical research and daily practice in both high- and low-resource setting. A 4-item clinical tool (CHANT: Clinical HIV-associated Neuropathy Tool) assessing symptoms (pain ... Read more >>

Resilience does not explain the dissociation between chronic pain and physical activity in South Africans living with HIV.

Antonia L Wadley, Duncan Mitchell, Peter R Kamerman,

Pain burden is high in people living with HIV (PLWH), but the effect of this pain on functionality is equivocal. Resilience, the ability to cope with adversity, may promote adaptation to pain, so we hypothesised that higher resilience would correlate with less pain-related impairment of activity. We recruited 197 black ... Read more >>

Polymorphisms in CAMKK2 may predict sensory neuropathy in African HIV patients.

Hayley Goullee, Antonia L Wadley, Catherine L Cherry, Richard J N Allcock, Michael Black, Peter R Kamerman, Patricia Price,

HIV-associated sensory neuropathy (HIV-SN) is the most common neurological condition associated with HIV. HIV-SN has characteristics of an inflammatory pathology caused by the virus itself and/or by antiretroviral treatment (ART). Here, we assess the impact of single-nucleotide polymorphisms (SNPs) in a cluster of three genes that affect inflammation and neuronal ... Read more >>

Progression of pain in ambulatory HIV-positive South Africans.

Noko R Mphahlele, Peter R Kamerman, Duncan Mitchell,

Cross-sectional studies report that pain in ambulatory HIV-infected individuals is frequent and often undermanaged. Expanding access to HIV treatment in developing countries means that infected individuals are living longer, but there is a dearth of pain-directed studies from developing countries that describe the progression of pain and its treatment over ...
