The Prevalence of Chronic Pain among Adults in India

Chronic nonspecific multiple-sites pain [CNMSP] of unknown etiology: Biopsychosocial method of evaluation for the primary care level

Background

Understanding and dealing with chronic nonspecific pain (CNP) is the important entity at primary care hospital. Chronic nonspecific multiple-site pain [CNMSP] of unknown etiology creates diagnostic and therapeutic challenges for primary care physicians due to lack of guidance regarding evaluation and treatment.

Aims and Objectives

To classify and formulate the evaluation, treatment strategies, and prediction of prognosis of patients with CNMSP of unknown etiology.

Methods

Patients present with CNMSP of more than 3-month duration without any obvious medical cause. The biopsychosocial [BPS] model with 3P model was applied to see the biological, psychological, and social factors behind persistence. Finally, patients were classified into four groups for evaluation response to treatment and relapse rates in 12-month follow-up.

Results

Of the total 243 patients of CNMSP, 243 [96.3%] were females. Sixty [24.7%] patients had short duration, and 183 [75.3%] had long duration. Headache was in 115 [47%], low back pain ± leg pain in 96 [39.4%], cervical pain ± shoulder/arm pain in 83 [34.1%], and diffuse body pain in 50 [20.5%] in various combinations. A total of 155 [63.8%] patients had high somatization-sensitization index (SSI), and 144 [59.3%] had low ferritin level. Group 1 [high SSI and low ferritin] had 37.9% of patients, group 2 [high SSI and normal ferritin] had 25.9% of patients, group 3 [low to medium SSI with low ferritin] had 21.4% of patients, and group 4 [low to medium SSI with normal ferritin] had 14.8% of patients. Response to pain symptoms was better in group 1, and relapse rate was higher in group 2.

Conclusion

CNMSP of unknown etiology itself is a heterogeneous entity, and assessment based on the BPS model can be very useful to understand the treatment plan and outcome of these patients.

Socioeconomic variation in the prevalence of pain by anatomical sites among middle-aged and older adults in India: a cross-sectional study

BACKGROUND

Pain is a significant global public health concern, particularly among individuals aged 45 and above. Its impact on the overall lifestyle of the individuals varies depending on the affected anatomical parts. Despite its widespread impact, there is limited awareness of the attributes of pain, making effective pain management challenging, particularly in India. This study aims to estimate the prevalence and variation in pain in different anatomical sites among middle-aged and older adults in India.

METHODS

A cross-sectional design was employed, utilising data from the first wave of the Longitudinal Aging Study in India (LASI), 2017-2018. The age-sex adjusted prevalence of pain by anatomical sites (the back, joints, and ankles) was estimated using a multivariate logistic regression model.

RESULTS

47% of individuals aged 45 years and above reported joint pain, 31% reported back pain and 20% suffered from ankle or foot pain. The prevalence of pain at all the anatomical sites increased with age and was reported higher among females. Relative to respondents aged 45-59 years, those aged 75 years and older exhibited a 41% higher likelihood of experiencing back pain (AOR: 1.41, 95% CI: 1.19-1.67), a 67% higher likelihood of joint pain (AOR: 1.67, 95% CI: 1.49-1.89), and a 32% higher likelihood of ankle/foot pain (AOR: 1.32, 95% CI: 1.16-1.50). In comparison to males, females had a 56% higher likelihood of encountering back pain (AOR: 1.56, 95% CI: 1.40-1.74), a 38% higher likelihood of joint pain (AOR: 1.38, 95% CI: 1.27-1.50), and a 35% higher likelihood of ankle/foot pain (AOR: 1.35, 95% CI: 1.17-1.57). We also found significant regional variations in pain prevalence, with higher rates in the mountainous regions of India.

CONCLUSION

This research highlights the high burden of pain in major anatomical sites among middle-aged and older adults in India and emphasises the need for increased awareness and effective pain management strategies.

Opioid use disorder and role of yoga as an adjunct in management (OUDARYAM): Study protocol for a randomized controlled trial

Background

The proposed research aims to test the effects and mechanisms of a six-month yoga-based intervention as an add-on to standard treatment in opioid use disorder (OUD) by conducting a randomized controlled study with the following primary outcome variables: 1) clinical: abstinence (opioid negative urine test), and reductions in pain and craving, and 2) mechanisms: reward circuit activation in response to opioid visual cue craving paradigm, activation in response to a cognitive control task, and resting state functional connectivity through fMRI, and plasma beta-endorphin levels. Secondary outcome variables are perceived stress, anxiety, sleep quality, cognitive performance, pain threshold, buprenorphine dosage and side effects, withdrawal symptoms, socio-occupational functioning, vedic personality traits, heart rate variability, serum cortisol, and brain GABA levels through magnetic resonance spectroscopy (MRS).

Methods

In this single-blinded, randomized, controlled, parallel-group superiority trial with 1:1 allocation ratio, 164 patients with OUD availing the outpatient/ inpatient clinical services at a tertiary mental healthcare hospital in India will be enrolled after giving informed consent. Consecutive consenting patients will be randomly allotted to one of the two groups - yoga arm (standard treatment + yoga-based intervention), or waitlist group (standard treatment alone). Allocation concealment will be followed, the clinicians, outcome assessors and data analysts will remain blind to subject-group allocation. A validated and standardized yoga program for OUD will be used as an intervention. Participants in the yoga arm will receive 10 supervised in-person sessions of yoga in the initial two weeks followed by tele-yoga sessions thrice a week for the next 22 weeks. The wait-list control group will continue the standard treatment alone for 24 weeks. Assessments will be done at baseline, two weeks, 12 weeks, and 24 weeks. Data from all randomized subjects will be analysed using intent-to-treat analysis and mixed model multivariate analysis.

Dissemination

Findings will be disseminated through peer-reviewed publication, conference presentations, and social media.

Trial registration number

The trial has been registered under Clinical Trials Registry-India with registration number CTRI/2023/03/050737.

Role of opioid use in gastrointestinal obstruction and perforation: A retrospective review

INTRODUCTION

Pain is one of the most common complaints that brings a patient to a hospital. For this, usually, the patient might have already consumed various types of pain killer combinations, either prescribed or over-the-counter. In some of these cases, a patient consumes these medicines unmonitored for a long time and then comes with complications, among which gastrointestinal tract obstruction and perforation are the most life threatening.

MATERIALS AND METHODS

Case files from the Department of Surgery were retrieved and studied. Patients were contacted telephonically for details of drug abuse history. These were then further studied in detail.

RESULTS

Forty-eight (68 percent) patients out of a total of 78 had a history of drug abuse. The most commonly abused pain killer was a combination of anti-inflammatory and other salts, which was found in 22 (46 percent) patients, followed by tramadol, NSAIDs, opium, and alcohol (23, 17, 10, and 4 percent, respectively). These groups were comparable in socio-demographic details except in the mean age, occupation, and gender distribution, and the difference was significant (p < 0.01). The most common cause for starting to use any of the above-mentioned pain killer was persistent pain. The most common site of obstruction in drug abusers was the stomach (60 percent), followed by the small intestine (38 percent) and the large intestine (2 percent).

LIMITATIONS

(1) This is an observational retrospective record review. (2) Records were studied in hospital settings, so results should be generalized cautiously. (3) Risk of recall bias is present.

CONCLUSION

Pain killers should always be prescribed with caution and for a short duration. Alternative options for pain relief should be made available, and doctors should be trained. Drug abusers tend to have a gastrointestinal complication at an early age, which means they are prone to further complications and recurrence if the problem is not addressed on time.

Who Benefits the Most From Different Psychological Chronic Pain Treatments? An Exploratory Analysis of Treatment Moderators

Different psychological chronic pain treatments benefit some individuals more than others. Understanding the factors that are associated with treatment response-especially when those factors differ between treatments-may inform more effective patient-treatment matching. This study aimed to identify variables that moderate treatment response to 4 psychological pain interventions in a sample of adults with low back pain or chronic pain associated with multiple sclerosis, spinal cord injury, acquired amputation, or muscular dystrophy (N = 173). The current study presents the results from secondary exploratory analyses using data from a randomized controlled clinical trial which compared the effects of 4 sessions of cognitive therapy (CT), hypnosis focused on pain reduction (HYP), hypnosis focused on changing pain-related cognitions and beliefs (HYP-CT), and a pain education control condition (ED). The analyses tested the effects of 7 potential treatment moderators. Measures of primary (pain intensity) and secondary (pain interference, depression severity) outcome domains were administered before and after the pain treatments, and potential moderators (catastrophizing, hypnotizability, and electroencephalogram (EEG)-assessed oscillation power across five bandwidths) were assessed at pre-treatment. Moderator effects were tested fitting regression analyses to pre- to post-treatment changes in the three outcome variables. The study findings, while preliminary, support the premise that pre-treatment measures of hypnotizability and EEG brain activity predict who is more (or less) likely to respond to different psychological pain treatments. If additional research replicates the findings, it may be possible to better match patients to their more individually suitable treatment, ultimately improving pain treatment outcomes. PERSPECTIVE: Pre-treatment measures of hypnotizability and EEG-assessed brain activity predicted who was more (or less) likely to respond to different psychological pain treatments. If these findings are replicated in future studies, they could inform the development of patient-treatment matching algorithms.

Mindfulness influences the psycho-social dimension of chronic pain: A randomized controlled clinical trial in Indian context

Background and Aims

In India, the awareness about the psycho-social dimension of chronic pain is minimal among physicians and patients. The research with community-based group therapies (like mindfulness) to address the psycho-social aspects in chronic pain patients remains limited. The aim of this randomized controlled trial was to see the effects of mindfulness on pain intensity, pain catastrophizing, chronic pain acceptance, perceived stress, well-being, and mindfulness characteristics.

Materials and Methods

In this two-site, parallel group, clinical trial, 170 patients attending pain outdoors of two government hospitals in West Bengal, India, were randomized to attend five weekly in-person mindfulness sessions (cases) or usual care sessions (controls) within the hospital premises. Pre-program and post-program data were collected and analyzed using statistical methods like repeated measures analysis of variance.

Results

In participants of the mindfulness group, significant changes post session were noted in pain intensity [F(1,326) = 15.0122; P = 0.0001291], pain acceptance [F(1,326) = 4.5311; P = 0.03403], and perceived stress score [F(1,326) = 13.2788; P = 0.0003122] compared to pre-session. The changes in pain catastrophizing, World Health Organization well-being and Freiburg mindfulness inventory scores were non-specific.

Conclusion

Mindfulness had a positive influence on pain intensity, pain acceptance, and perceived stress of Indian chronic pain patients. The effects on pain catastrophizing, mindfulness characteristics, and well-being (non-specific) were also encouraging. Further studies will be required to substantiate these results.

Prevalence, Severity, and Determinants of Pain in Thalassemia

As the life expectancy in thalassemia is improving, pain is being recognized as an emerging problem. To document the pain prevalence and severity in patients with transfusion-dependent thalassemia all transfusion-dependent thalassemia patients >10 years of age (n = 165) attending the Thalassemia Day Care Center were assessed for pain prevalence, severity, and its effect on various life activities using the Brief Pain Inventory. Their medical records were reviewed for the presence of various co-morbidities. Pain was reported by 62.4% of participants with 35.2% and 59.4% of participants, reporting pain in the past 1 and 4 weeks respectively. A significantly higher pain prevalence was reported in females (p = .037), patients residing in urban areas (p = .038), and employed participants (p = .038). The commonest sites of pain were the lower back and calves. General activity (p = .02) and enjoyment of life (p = .02) were significantly affected due to pain in patients between 21 and 30 years of age. Female participants reported interference of pain with mood (p = .03). A significant correlation of pain prevalence was found with higher average serum ferritin (p = .015), moderate to severe liver iron concentration (p = .04), and lower levels of 25 hydroxyvitamin D levels (p = .03). Pain is an emerging cause of morbidity in thalassemia. The study found a significant association of pain with modifiable factors such as serum ferritin, LIC, and 25 (OH) vitamin D levels.

Examining the Association of Pain and Pain Frequency With Self-Reported Difficulty in Activities of Daily Living and Instrumental Activities of Daily Living Among Community-Dwelling Older Adults: Findings From the Longitudinal Aging Study in India

OBJECTIVES

We examined the prevalence and associations of self-reported difficulty in activities of daily living (ADL) and instrumental activities of daily living (IADL) with pain among community-dwelling older adults in India. We also explored the interaction effects of age and sex in these associations.

METHODS

We used the Longitudinal Ageing Study in India (LASI) Wave 1 data (2017-2018). Our unweighted sample included 31,464 older adults aged 60 years and above. Outcome measures were having difficulty in at least 1 ADL/IADL. We conducted multivariable logistic regression analyses to examine the association of pain with functional difficulties controlling for selected variables.

RESULTS

A total of 23.8% of older adults reported ADL and 48.4% reported IADL difficulty. Among older adults who reported pain, 33.1% reported difficulty in ADL and 57.1% reported difficulty in IADL. The adjusted odds ratio (aOR) for ADL was 1.83 (confidence interval [CI]: 1.70-1.96) and for IADL was 1.43 (CI: 1.35-1.51) when respondents reported pain compared with those without pain. Older adults who reported frequent pain had 2.28 and 1.67 times higher odds of ADL (aOR: 2.28; CI: 2.07-2.50) and IADL difficulty (aOR: 1.67; CI: 1.53-1.82) compared with those with no pain. Additionally, age and sex of the respondents significantly moderated the associations of pain and difficulty in ADL and IADL.

DISCUSSION

Given the higher prevalence and likelihood of functional difficulties among older Indian adults who experienced frequent pain, interventions to mitigate pain in this vulnerable population are needed to ensure active and healthy aging.

Curcumin Stereoisomer, Cis-Trans Curcumin, as a Novel Ligand to A1 and A3 Adenosine Receptors

Adenosine receptors (ARs) are being explored to generate non-opioid pain therapeutics. Vanilloid compounds, curcumin, capsaicin, and vanillin possess antinociceptive properties through their interactions with the transient receptor potential channel family. However, their binding with adenosine receptors has not been well studied. The hypothesis in this study was that a vanilloid compound, cis-trans curcumin (CTCUR), binds to each of the two Gi-linked AR subtypes (A₁AR and A₃AR). CTCUR was synthesized from curcumin (CUR) using the cavitand-mediated photoisomerization technique. The cell lines transfected with the specific receptor (A₁AR or A₃AR) were treated with CTCUR or CUR and the binding was analyzed using competitive assays, confocal microscopy, and docking. The binding assays and molecular docking indicated that CTCUR had Ki values of 306 nM (A₁AR) and 400 nM (A₃AR). These values suggest that CTCUR is selective for Gi-linked ARs (A₁AR or A₃AR) over Gs-linked ARs (A_2AAR or A_2BAR), based on our previous published research. In addition, the docking showed that CTCUR binds to the toggle switch domain of ARs. Curcumin (CUR) did not exhibit binding at any of these receptors. In summary, CTCUR and other modifications of CUR can be developed as novel therapeutic ligands for the Gi-linked ARs (A₁AR and A₃AR) involved with pain and cancer.

Prevalence of pain and its treatment among older adults in India: a nationally representative population-based study

ABSTRACT

There were no estimates of the prevalence of pain and its treatment in the older population of India obtained from face-to-face interviews with a nationally representative sample. We addressed this evidence gap by using data on 63,931 individuals aged 45 years and older from the 2017/2018 Longitudinal Ageing Study in India. We identified pain from an affirmative response to the question: Are you often troubled by pain? We also identified those who reported pain that limited usual activities and who received treatment for pain. We estimated age- and sex-adjusted prevalence of pain, pain limiting usual activity and treatment, and compared these estimates across states and sociodemographic groups. We used a multivariable probit model to estimate full adjusted differences in the probability of each outcome across states and sociodemographic groups. We estimated that 36.6% (95% confidence interval [CI]: 35.3-37.8) of older adults in India were often troubled by pain and 25.2% (95% CI: 24.2-26.1) experienced pain limiting usual activity. We estimated that 73.3% (95% CI: 71.9-74.6) of those often troubled by pain and 76.4% (95% CI: 74.9-78.0) of those with pain that limited usual activity received treatment. There was large variation in each outcome across states. Fully adjusted prevalence of pain and pain limiting usual activity were higher among individuals who were female, older, less educated, rural residents, and poorer. Prevalence of treatment among those troubled by pain was lower among socially disadvantaged groups.

Association of pain and quality of life among middle-aged and older adults of India

BACKGROUND

India is passing through a phase of demographic and epidemiological transition where ageing and chronic morbidities are being more common. Though studies have examined the prevalence and risk factors of pain and other chronic morbidities, nationally representative research examining the association of pain and quality of life (QoL) is limited in India. This study examines the association between pain and QoL among middle-aged and older adults in India.

METHODS

This study uses the data from wave 1 of the Longitudinal Ageing Study in India (LASI) conducted in 2017-18. This study is restricted to 58,328 individuals from all states (except Sikkim), aged 45 years and above. The quality of life is measured in 6 domains (physical, psychological, social, environment, general health and life satisfaction) with 21 variables that range from 0 to 100. The principal component analysis was used to generate a composite score of QoL and the multiple linear regression was used to show the association between pain and quality of life.

RESULTS

It is estimated that approximately 37% of Indian middle-aged and older populations were often troubled with pain. Pain prevalence increase with age and is more common among older adults aged 75 + years (43.37%; 95% CI, 40.95-45.80), and female (41.38%; 95% CI, 39.36-43.39). The average QoL score among those with pain was 81.6 compared to 85.2 among those without pain. QoL was lower among elderly age 75 and above, females, rural residents and illiterates. Controlling for socio-demographic factors, pain reduces the QoL by 2.57 points (β= -2.57; 95% CI, -3.02 - -2.11).

CONCLUSION

Pain reduces the quality of life among middle-aged adults and older adults in India. This evidence could potentially help the policymakers to consider pain as a significant determinant of quality of life in India.

Relationship between behavioral and mood responses to monetary rewards in a sample of Indian students with and without reported pain

Physical pain has become a major health problem with many university students affected by it worldwide each year. Several studies have examined the prevalence of pain-related impairments in reward processing in Western, Educated, Industrialized, Rich, and Democratic (WEIRD) countries but none of the studies have replicated these findings in a non-western cultural setting. Here, we aimed to investigate the prevalence of physical pain symptoms in a sample of university students in India and replicate our previous study conducted on university students in Switzerland, which showed reduced mood and behavioral responses to reward in students with significant pain symptoms. We grouped students into a sub-clinical (N = 40) and a control group (N = 48) to test the association between pain symptoms and reward processes. We used the Fribourg reward task and the pain sub-scale of the Symptom Checklist (SCL-27-plus) to assess physical symptoms of pain. We found that 45% of the students reported high levels of physical symptoms of pain and interestingly, our ANOVA results did not show any significant interaction between reward and the groups either for mood scores or for outcomes related to performance. These results might yield the first insights that pain-related impairment is not a universal phenomenon and can vary across cultures.

Elder care: The need for interprofessional collaboration between Family Physicians, Clinical Pharmacists, and Physiotherapists in home-based primary care teams

Background

Elderly patients with pain and falls are commonly seen in family practice.

Aims

(1) Highlight the role of a physiotherapist in the primary care team; (2) Discuss the collaboration between a family physician clinical pharmacist dyad and the physiotherapist that emerged; and (3) Share practice tools that emerged from our teamwork.

Settings and Design

Home Based Primary Care Practice (a core component of family practice). We have described our home based primary care practice model in earlier publications. Our model utilizes a team based approach to address the prevention of diseases, promotion of health, provision of care for acute and chronic conditions (especially concurrent multi morbidity), and delivery of rehabilitation services in the home setting.

Methods and Materials

Selection of three cases from our daily practice. Reflective discussion and learning towards arriving at novel insights and improving our care model.

Results

Case discussion from the perspectives of the family physician, clinical pharmacist, and physiotherapist reveal important insights on the roles, responsibilities, benefits and tensions. A process flow to facilitate team based care is also outlined along with a referral communication tool.

Conclusion

For our population of the elderly with falls and pain, there was a need for a physiotherapist, as part of the team, instead of a mere referral service. This was felt because of the growing needs of patients, multiple gaps in communication with external referrals, mismatch of values and approaches, and missed opportunities for high quality care. This enhances access, optimizes clinical outcomes, delivers patient centred care, reduces unnecessary hospitalizations, and avoids catastrophic and unwarranted costs. The paper highlights the critical need for interprofessional collaboration between family physicians, clinical pharmacists and Physiotherapist in elder care.

Acute and sub chronic toxicity studies with herbal pain relieving formula (Rhuleave-K™) in rats

Rhuleave-K™ is a proprietary combination of Curcuma longa extract, Boswellia serrata extract and black sesame seed oil. Acute toxicity was evaluated as per OECD guidelines 423. Rhuleave-K™ was fed at 2000 mg/kg to overnight fasted female rats. Clinical signs of abnormality and mortality was observed daily for 14 days. Sub-chronic toxicity was studied by feeding Rhuleave-K™ at 100, 500 and 1000 mg/kg/day to rats as per OECD guidelines 408. After 90 days feeding, heamatological and biochemical parameters were analyzed. Histopathology of all the major organs was also studied. In the acute toxicity study, there was no clinical sign of toxicity in any of the rat at maximum dose of 2000 mg/kg. The LD50 was computed as >2000 mg/kg in rats. The repeated dosing of Rhuleave-K™ at the maximum dose level of 1000 mg/kg for 90 days did not induce any observable toxic effects in rats, when compared to its corresponding control. The hematology and biochemistry profile of treated rats was similar to control animals and difference was non-significant (p > 0.05). The histopathology of major organs of all the control and treated animals was normal. In this study the NOAEL for Rhuleave-K™ was calculated as 1000 mg/kg daily in rats.

Chronic neck pain and respiratory dysfunction: a review paper

Background

Neck pain is one of the most frequently reported musculoskeletal complaints among adults; its prevalence in the world is ranging from 16.7 to 75.1%. It can have an impact on a person’s physical, psychological, and social well-being. Along with pain, disability, muscle weakness, and alterations in the posture, neck pain patients are likely to develop affection of the respiratory function as reported in numerous studies. However, these patients are primarily managed with a musculoskeletal perspective with little or no emphasis to the changes observed in the respiratory system. There is a paucity of literature evaluating the need for respiratory rehabilitation in these patients.

Main body

All relevant published literature related to respiratory dysfunction in patients with chronic neck pain were critically reviewed in this study. Patients having chronic neck pain were found to have alterations in respiratory function in terms of reduced lung volumes, reduced chest mobility, and decreased respiratory muscle strength. Various factors such as decreased cervical range of motion, decreased strength of deep neck flexors and extensors, forward head posture, and pain are known to cause these dysfunctions. Respiratory system intervention in the form of breathing re-education and respiratory exercises are significantly proven to improve treatment outcomes.

Conclusion

There is limited literature relating to respiratory dysfunction and its management in neck pain patients. Incorporation of both respiratory and musculoskeletal assessments can enhance their treatment outcomes. Additionally, it can be suggested to consider intervention in the form of respiratory rehabilitation while strategizing treatment goals for these patients.

Prevalence and correlates of pain and associated depression among community-dwelling older adults: Cross-sectional findings from LASI, 2017-2018

BACKGROUND

Health practitioners often meet older persons suffering both from pain and depression. The study aimed to examine the factors associated with pain among older individuals and its association with major depression. In addition, the interaction between self-rated health (SRH), wealth status, and pain that is associated with depression are explored.

METHODS

We used data from the Longitudinal Aging Study in India (LASI). Participants included 15,098 male and 16,366 female adults aged 60 years or older. Univariate and bivariate analyses along with χ² tests were conducted in the initial stage. Binary logistic regression analyses were performed to fulfill the objectives. Major depression was calculated using Short Form Composite International Diagnostic Interview.

RESULTS

A proportion of 39.6% older individuals (n = 12,686) reported pain and 8.7% older adults (n = 2657) suffered from depression. Older adults who suffered from pain frequently were more likely to be depressed than those who never suffered from pain (adjusted odds ratio [AOR]: 1.70; confidence interval [CI]: 1.38-2.09). The interaction of pain, SRH, and household wealth status on depression found that older adults with pain who reported poor SRH (AOR: 4.18; CI: 3.50-5.00) or belonged to rich households (AOR: 2.27; CI: 1.84-2.80) had higher odds of suffering from depression, compared to older adults with no pain and good SRH or no pain and belonged to poor households.

CONCLUSION

It is highlighted that pain is quite common in older people, and is linked to depression especially among older people with poor SRH. Thus, routine evaluation of pain and associated symptoms of mental illnesses should be performed for ensuring healthy aging.

Protocol based pain management by Ayurveda parasurgical procedures W.S.R to musculoskeletal pain and its critical appraisal - An open labeled clinical trial

BACKGROUND

Pain has globally become an attention problem which causes discomfort by affecting the body as well as the mind. The International association of pain estimated that 1 in 5 patients experiences the pain, i.e. 30% of world population. 19.3% (180-200 million) of the total population in India suffer from chronic pain and its severity appeals early approach of patients to hospitals. Ayurveda being the oldest medical science emphasized its importance and treatment of pain with both pharmacological and non-pharmacological (Parasurgical) methods.

OBJECTIVE

To evaluate the efficacy of non-pharmacological (para surgical) procedures in the management of pain.

MATERIALS AND METHOD

Total 100 patients with chronic musculoskeletal pain fulfilling the inclusion criteria were recruited by assessing the site, severity and nature of pain. A special protocol was framed by incorporating Ayurveda treatment principles by using Para surgical procedures such as Agnikarma (Therapeutic burn), Jalauka (leech therapy), Alabu (Cupping therapy) and Siravyadha (Vein puncture). The parameters like VAS and VDS pertaining to pain were assessed from baseline and at various time points. Statistical analysis was performed by using Wilcoxon match paired test to assess the results.

RESULTS

The VAS and VDS scale were used to assess the efficacy of para-surgical procedures which was found to be significant (p < 0.0001) from baseline and at various time points.

CONCLUSION

Protocol based pain management by various para surgical procedures was found effective in the management of chronic musculoskeletal pain. The ambiguity in selection of proper parasurgical procedure for pain management is justified by following the protocol.

Back pain and treatment seeking among community-dwelling older adults: Findings from a population-based survey

This study explores the prevalence and factors associated with back pain and treatment seeking of older people. We used data from the Longitudinal Aging Study in India (LASI), 2017-18. A sample of 31,464 older adults aged 60 years and above was considered for this study. Chi-square test was used to find the significance level for bivariate associations. Additionally, Heckprobit selection model was employed to fulfill the objectives. Among 34% of the participants suffering from back pain, 46.2% used external application, followed by analgesics (40.8%) and therapy (6.6%). Older adults with higher education had a higher probability of seeking therapy than those with no or primary education [β:0.25; CI:0.03,0.48]. Participants from the highest wealth quintile had higher probability of seeking therapy than those from the lowest [β:0.41; CI:0.23,0.58]. The use of therapy, which is globally recommended first line of management for back pain, was least utilized and must be promoted.

Co-occurrence of chronic pain, depressive symptoms, and poor sleep quality in a health check-up population in China:A multicenter survey

OBJECTIVES

This study aimed to investigate the cooccurrence of chronic pain (CP), depressive symptoms, and poor sleep quality in terms of prevalence and associated factors in a nationwide health check-up population in China.

METHODS

This multicenter cross-sectional survey was performed in 2017. All the participants aged ≥18 years from eight health check-up institutions in 6 provinces and cities were invited to complete a self-report health questionnaire through online resources.

RESULTS

132,444 participants completed the online survey and the overall prevalence of CP and that of the three symptoms were 11.0% (95% confidence interval [95% CI]: 10.8-11.1) and 2.7% (95% CI: 2.6-2.8), respectively. The cooccurrence of all three symptoms increased with age, being higher in the female, widowed, unemployed, and lower education level groups. The respondents with multiple symptoms reported poorer self-rated health. Binary logistic regression analyses identified female sex (adjusted odds ratio [aOR]: 1.51; 95% CI: 1.42-1.62), a widowed status (aOR: 1.39; 95% CI: 1.04-1.84), a lower education level (aORs ranging from 1.46 to 2.47), and having one or more chronic diseases (aORs ranging from 1.43 to 2.02) to be significantly associated with reporting all three symptoms (all P ˂0.05). While long-term medication and regular exercise were the protective factors.

CONCLUSION

This study suggests that the cooccurrence of the three symptoms accounts for a certain proportion of the Chinese health check-up population. Integrated interventions that address CP and mental health cooccurrence may be an essential target for heath management in this population to tackle this considerable burden.

Disentangling comorbidity in chronic pain: A study in primary health care settings from India

OBJECTIVES

The study examined the prevalence, sociodemographic, and clinical correlates of chronic pain among primary care patients in the state of Kerala, India. It also examined the patterns and relationships of chronic physical and mental health conditions with chronic pain.

METHODS

This study is a cross-sectional survey conducted among 7165 adult patients selected randomly by a multi-stage stratified design from 71 primary health centers. The questionnaires administered included Chronic pain screening questionnaire, self-reported Chronic physical health condition checklist, Patient Health Questionnaire-SADS, The Alcohol Use Disorders Identification Test, Fagerström Test for Nicotine Dependence, WHO Disability Assessment Schedule and WHOQOL- BREF for Quality/Satisfaction with Life. The prevalence and comorbid patterns of chronic pain were determined. Logistic regression analysis and generalized linear mixed-effects model was employed to examine the relationship of chronic pain to socio-demographic variables and examined physical and mental health conditions.

RESULTS

A total of 1831 (27%) patients reported chronic pain. Among those with chronic pain, 28.3% reported no co-occurring chronic mental or physical illness, 35.3% reported one, and 36.3% reported multi-morbidity. In the multivariate analysis, patients with chronic pain when compared to those without had higher odds of being older, female, having lower education, not living with their family, greater disability, and poor satisfaction with life. Chronic pain was independently associated with both medical (hypertension, diabetes mellitus, tuberculosis, arthritis, and other medical illnesses) and mental health conditions (depressive disorders, anxiety disorders, and tobacco dependence). It showed a varying strength of association and additive effect with increasing number of co-occurring physical and mental illnesses.

CONCLUSIONS

Chronic pain is a common condition among primary care attendees associated with significant burden of medical and mental health comorbidity. The findings highlight the need to incorporate treatment models that will ensure appropriate management to improve outcomes within the resource constraints.

Excess Body Mass and Leisure Time Physical Activity in the Incidence and Persistence of Chronic Pain

OBJECTIVE

To estimate the effects of excess body mass and leisure time physical activity on the incidence and persistence of chronic pain.

DESIGN

A prospective cohort study.

METHODS

As a part of the Finnish Helsinki Health Study, we included three cohorts of employees of the City of Helsinki (18,562 observations) and defined incident chronic pain as having pain in any part of the body for more than three months at follow-up in participants without chronic pain at baseline (N = 13,029 observations). Persistent chronic pain was defined as having pain for more than three months at both baseline and follow-up (N = 5,533 observations).

RESULTS

Overweight (adjusted odds ratio [OR] = 1.18, 95% confidence interval [CI] = 1.06-1.31) and obesity (OR = 1.65, 95% CI = 1.45-1.88) increased the incidence of chronic pain. Moreover, overweight (OR = 1.16, 95% CI = 1.02-1.32) and obesity (OR = 1.48, 95% CI = 1.26-1.74) increased the risk of persistent chronic pain. Vigorous leisure time physical activity reduced the incidence of chronic pain (OR = 0.85, 95% CI = 0.75-0.96). Physical activity did not influence the risk of persistent chronic pain. Furthermore, overweight/obesity modified the effect of leisure time physical activity on incident chronic pain. Inactive overweight or obese participants were at the highest risk of chronic pain (OR = 1.71, 95% CI = 1.40-2.09), while the OR dropped to 1.44 (95% CI = 1.19-1.75) in moderately active overweight or obese participants and to 1.20 (95% CI = 0.97-1.47) in highly active overweight or obese participants.

CONCLUSIONS

Obesity not only increases the risk of developing chronic pain, but also increases the risk of persistent pain, while leisure time physical activity reduces the risk of developing chronic pain.

Analysis of genetically independent phenotypes identifies shared genetic factors associated with chronic musculoskeletal pain conditions

Chronic musculoskeletal pain affects all aspects of human life. However, mechanisms of its genetic control remain poorly understood. Genetic studies of pain are complicated by the high complexity and heterogeneity of pain phenotypes. Here, we apply principal component analysis to reduce phenotype heterogeneity of chronic musculoskeletal pain at four locations: the back, neck/shoulder, hip, and knee. Using matrices of genetic covariances, we constructed four genetically independent phenotypes (GIPs) with the leading GIP (GIP1) explaining 78.4% of the genetic variance of the analyzed conditions, and GIP2–4 explain progressively less. We identified and replicated five GIP1-associated loci and one GIP2-associated locus and prioritized the most likely causal genes. For GIP1, we showed enrichment with multiple nervous system-related terms and genetic correlations with anthropometric, sociodemographic, psychiatric/personality traits and osteoarthritis. We suggest that GIP1 represents a biopsychological component of chronic musculoskeletal pain, related to physiological and psychological aspects and reflecting pain perception and processing.

Yakov Tsepilov, Maxim Freidin et al. find that chronic musculoskeletal pain conditions at four distinct anatomical sites share a common genetic background. The authors constructed genetically independent phenotypes (GIP) from principal components analysis of the different pain phenotypes and used the GIPs to perform genome-wide association studies to identify underlying genetic factors.

Prevalence of chronic pain and high-impact chronic pain in Saudi Arabia

Objectives:

To estimate the prevalence of chronic pain (CP) and high-impact chronic pain (HICP) in a sample of the general adult population in Saudi Arabia.

Methods:

This is a cross-sectional online survey (N=24,265). Forty data collectors from 5 regions of Saudi Arabia approached people to complete the questionnaires through different social media applications, using a validated survey in Arabic language.

Results:

Chronic pain and HICP prevalences in the Saudi adult population were found to be 46.4% (CP) and 4% (HICP), with a higher prevalence among women and elderly. Chronic back pain was the most reported pain location. Half of the respondents reported dissatisfaction with pain services. Greater prevalence of HICP was found among women, elderly, unemployed, and those with low-income status. Patients with HICP were more likely to have more healthcare utilization and have more negative impacts on their physical and psychological wellbeing.

Conclusion:

Chronic pain and HICP are common in Saudi Arabia, especially among females and elderly, suggesting a public health problem. This calls for collaborative efforts at various levels of the social hierarchy to ensure the provision of effective management of CP in Saudi Arabia.

Prevalence of chronic pain in developing countries: systematic review and meta-analysis

Supplemental Digital Content is Available in the Text.

Chronic pain (CP) is prevalent worldwide. Current reports on its prevalence in developing countries are heterogeneous, and to date, there is no quantitative synthesis providing a general estimation of its magnitude in the developing world. The goal of this study was to estimate the pooled prevalence of CP in the general population in developing countries. This was a PROSPERO-registered CRD42019118680 systematic review including population-based cross-sectional studies on CP from countries with ≤0.8 human developing index. We calculated prevalence using both random effects and fixed effects. Heterogeneity was calculated by the Cochran Q test and the I² statistic. Publication bias was evaluated by visual inspection of the Egger funnel plot, as well as by the Begg rank test and the Egger linear test. Sources of heterogeneity were also explored in subgroup analyses. Twelve studies with a total of 29,902 individuals were included in this meta-analysis, of which 7263 individuals were identified with CP. The overall pooled prevalence of CP after correction for publication bias was 18% (95% confidence interval: 10%–29%), the sample presenting significant heterogeneity (I2 = 100%, P < 0.001). Subgroup analyses demonstrated that year of publication and the adopted threshold for pain chronicity could partially explain the observed heterogeneity (P < 0.05). The proportion of individuals with CP in the general population of developing countries was 18%. However, reports of prevalence have high variability, especially related to year of publication and the threshold level adopted for pain chronicity.

A Cross-Sectional Web-Based Survey of Medical Practitioners in India to Assess their Knowledge, Attitude, Prescription Practices, and Barriers toward Opioid Analgesic Prescriptions

CONTEXT

Inadequate training of medical practitioners is a key factor responsible for inappropriate use of opioid analgesics.

AIMS

We assessed the current knowledge, attitude, prescribing practices, and barriers perceived by the Indian medical practitioners in three tertiary care hospitals toward the use of opioid analgesics.

SUBJECTS AND METHODS

Web-based survey of registered medical practitioner employed at three chosen tertiary health care institutions in New Delhi.

STATISTICAL ANALYSIS USED

Descriptive analysis of survey responses was carried out. Comparative analysis was done using Chi-square test, independent samples t-test, and Pearson correlation coefficient.

RESULTS

The response rate was 10.4% (n = 308). Two-thirds of the participants (61.7%) had never received formal pain management training, and 86.7% participants would like further training. Most participants (71.1%) agreed that opioids should be prescribed in cancer pain, while 26.3% agreed that opioids should be prescribed in noncancer pain. Half of the participants agreed that SOS (if necessary) dosing schedule (48.4%), low dosage (61.7%), and short duration of use (51.4%) could decrease the harmful effect of opioids. Lack of information about opioid-related policies and addiction potential were identified as the most common barriers to prescribing opioids. Those seeing more patients with chronic noncancer pain come across opioid misuse and diversion more often (P = 0.02). Those who understood addiction were more likely to agree that patients of chronic cancer pain with substance use disorders should be prescribed opioid analgesics (P < 0.01).

CONCLUSIONS

Indian medical practitioners felt the need for formal pain management training. There is a lack of consensus on how to manage the pain using opioid analgesics. Tough regulations on medical and scientific use of opioids are the most commonly reported barrier to prescribing them.

Chronic pain following thoracotomy for lung surgeries: It's risk factors, prevalence, and impact on quality of life - A retrospective study

Background and Aims:

Chronic post thoracotomy pain (CPTP) is a nagging complication and can affect quality of life (QOL). Studies conducted across globe have found a wide variability in the risk factors predisposing to chronic pain following thoracotomy. As no study on CPTP is available from India, we aim to detect the prevalence of CPTP, assess the predisposing factors implicated in its causation and study the impact of CPTP on QOL.

Methods:

After obtaining clearance from Institutional ethics committee, medical records of patients who underwent open posterolateral thoracotomy between January 2012 and December 2015 were reviewed. Data on perioperative variables, address, and contact number were collected from the patient records. All patients were mailed the Telugu translation of medical outcome study short form -36(MOS-SF-36) QOL questionnaire and were contacted telephonically to enquire about presence of CPTP and QOL. A univariate analysis was done to assess factors associated with CPTP and a multivariate logistic regression analysis was done subsequently to identify independent risk factors of CPTP. QOL indices were compared between those patients who suffered from CPTP and those who did not.

Results:

The prevalence of pain in our study was 40.86% (85/208). The factors implicated in the causation of CPTP were diabetes mellitus, preoperative pain, rib resection, and duration of chest tube drainage with odds ratio of 9.8, 2.6, 6.7, and 1.03, respectively. The health-related QOL showed poor scores in all domains in patients suffering from CPTP.

Conclusion:

The prevalence of CPTP was high. It significantly impacts health-related QOL.
