Effects of acupuncture and medical training therapy on depression, anxiety, and quality of life in patients with frequent tension-type headache: A randomized controlled study.

OBJECTIVES: To compare the effects of acupuncture and medical training therapy in combination or individually with usual care on quality of life, depression, and anxiety in patients with tension-type headache. METHODS: In this single-center, prospective, randomized, controlled, unblinded trial, 96 adults (38.7(+/-13.3) years of age; 75 females/20 males/one dropout) with frequent episodic or chronic tension-type headache were randomized to one of four treatment groups (n = 24). The treatment groups received six weeks of either acupuncture or medical training therapy as monotherapies or in combination (12 interventions each), or usual care. We assessed depressiveness (PHQ-9), anxiety (GAD-7), and health-related quality of life (SF-12) as secondary outcome parameters at baseline, six weeks, three months, and six months after initiation of treatment. Linear mixed models were calculated. RESULTS: Both, acupuncture (baseline to six-weeks change scores: mean: -2(standard deviation: 2.5 points), three months: -2.4(2.4), six-months -2.7(3.6)) and the combination of acupuncture and medical training therapy (-2.7(4.9), -2.2(4.0), -2.2(4.2)) (each within-group p < .05) significantly reduced depressiveness-scores (PHQ-9) to a greater extent than medical training therapy (-0.3(2.0), -0.5(1.6), -0.9(2.6)) or usual care alone (-0.8(2.9), 0.1(2.8), 0.2(3.6)). We found similar results with anxiety scores and the physical sum scores of the SF-12. No severe adverse events occurred. CONCLUSIONS: Acupuncture and the combination of acupuncture and medical training therapy elicit positive effects on depression, anxiety, quality of life, and symptom intensity in patients with episodic and chronic tension-type headache. Acupuncture appears to play a central role in mediating the therapeutic effects, underscoring the clinical relevance of this treatment. An additive benefit of the combination of both therapies does not appear to be relevant.Trial registration: Registered on 11 February 2019. German Clinical Trials Register, DRKS00016723.

Cytosine methylation in GABA B1 receptor identifies alcohol-related changes for men in blood and brain tissues.

AIMS: Alcohol use alters the reward signaling processes contributing to the development of addiction. We studied the effects of alcohol use disorder (AUD) on brain regions and blood of deceased women and men to examine sex-dependent differences in epigenetic changes associated with AUD. We investigated the effects of alcohol use on the gene promoter methylation of GABBR1 coding for GABAB receptor subunit 1 in blood and brain. METHODS: We chose six brain regions associated with addiction and the reward pathway (nucleus arcuatus, nucleus accumbens, the mamillary bodies, amygdala, hippocampus and anterior temporal cortex) and performed epigenetic profiling of the proximal promoter of the GABBR1 gene of post-mortem brain and blood samples of 17 individuals with AUD pathology (4 female, 13 male) and 31 healthy controls (10 female, 21 male). RESULTS: Our results show sex-specific effects of AUD on GABBR1 promoter methylation. Especially, CpG -4 showed significant tissue-independent changes and significantly decreased methylation levels for the AUD group in the amygdala and the mammillary bodies of men. We saw prominent and consistent change in CpG-4 across all investigated tissues. For women, no significant loci were observed. CONCLUSION: We found sex-dependent differences in GABBR1 promoter methylation in relation to AUD. CpG-4 hypomethylation in male individuals with AUD is consistent for most brain regions. Blood shows similar results without reaching significance, potentially serving as a peripheral marker for addiction-associated neuronal adaptations. Further research is needed to discover more contributing factors in the pathological alterations of alcohol addiction to offer sex-specific biomarkers and treatment.

Comparing DRD2 Promoter Methylation Between Blood and Brain in Alcohol Dependence.

AIMS: The dopamine receptor D2 (DRD2) is substantially involved in several forms of addiction. In addition to genetic polymorphisms, epigenetic mechanisms have emerged as an important means of regulation. Previously, DRD2 hypo- and hyper-methylation have been observed in alcohol use disorder (AUD). Blood samples are commonly used as a surrogate marker of epigenetic alterations in epigenetic research, but few specific comparisons between blood and brain tissue samples in AUD exist. METHODS: We used post-mortem brain tissue samples of 17 deceased patients with AUD and 31 deceased controls to investigate the relationship between blood and brain methylation of the DRD2 promoter. RESULTS: When investigating individual cytosine methylation sites (CpG), several significant differences were found in the nucleus accumbens and hippocampus in the study population. Investigating binding sites with significant differences in methylation levels revealed hypomethylated CpGs targeting mainly activating transcription factors. CONCLUSION: These findings support an altered transcription of the DRD2 gene in AUD specimens with a consecutively changed reward response in the brain. While methylation between specific brain regions and blood is comparable, our study further suggests that blood methylation cannot provide meaningful perspectives on DRD2 promoter methylation in the brain.

Quantitative Sensory Testing in Patients with Multisomatoform Disorder with Chronic Pain as the Leading Bodily Symptom-a Matched Case-Control Study.

OBJECTIVE: Chronic pain is a debilitating condition of multifactorial origin, often without physical findings to explain the presenting symptoms. Of the possible etiologies of persisting painful symptoms, somatoform disorders and functional somatic syndromes (FSS) are among the most challenging, with a prevalence of 8-20%. Many different somatoform disorders and FSS have overlapping symptoms, with pain being the most prevalent one. The concept of multisomatoform disorder (MSD) has been developed to acknowledge that fact. We hypothesized that the concept of MSD will be reflected in a distinct sensory profile of patients compared with healthy controls and possibly provide insight into the type and pathophysiology of the pain commonly experienced by patients. DESIGN: We performed comprehensive quantitative sensory testing (QST) in 151 patients and 149 matched controls. RESULTS: There were significant differences in the sensory profiles of patients compared with controls. Patients with MSD showed a combination of tactile and thermal hypesthesia combined with mechanical and cold hyperalgesia. This was true for measurements at test and control sites, with the exception of vibration detection threshold and mechanical pain threshold. Among the observed changes, a marked sensory loss of function, as evidenced by an increase in cold detection threshold, and a marked gain of function, as evidenced by a decrease of pressure pain threshold, were most notable. There was no evidence of concurrent medication influencing QST results. CONCLUSIONS: The observed somatosensory profile of patients with MSD resembles that of patients suffering from neuropathic pain with evidence of central sensitization.

[Care of Patients During Emergency Caesarian Section - Evaluation of Quality Characteristics from the Patients Point of View]. / Betreuung der Patientin während eines Notfallkaiserschnittes ­ Evaluation von Qualitätsmerkmalen aus Patientensicht.

BACKGROUND: An emergency caesarian section can be a terrifying experience for expectant mothers. Fear for her own life as well as her unborn child's is a traumatic event that can result in the development of post-traumatic stress disorder (PTSD). The aim of this survey was to define scales and items that describe the quality of care of parturients in cases of emergency caesarian section. METHODS: A pool of items was developed via a 2-step online Delphi survey administered to women who had undergone an emergency caesarian section. The resulting parameters were evaluated for relevance and validity in a larger patient collective. Lastly, we identified factors that could be grouped into relevant scales. RESULTS: After validating the results of the Delphi survey, 5 scales with 18 items were identified. They encompassed the following dimensions: "team external effect," "mother's level of information," "subjective evaluation," "personal integrity," and "after-care." These items could explain 58.2% of total variance and provide a stable factorial solution (KMO 0.76). CONCLUSION: To our knowledge, this is the first time a German criteria checklist has been developed to evaluate the care of expectant mothers undergoing an emergency caesarian section. This checklist can be used in addition to medical outcomes to measure quality of care. Further studies are needed to evaluate practical implementation and its impact on patient care.

EMG measured reaction time as a predictor of invalid symptom report in psychosomatic patients.

Background: Symptom validity tests (SVTs) and performance validity tests (PVTs) are important tools in sociomedical assessments, especially in the psychosomatic context where diagnoses mainly depend on clinical observation and self-report measures. This study examined the relationship between reaction times (RTs) and scores on the Structured Inventory of Malingered Symptomatology (SIMS). It was proposed that slower RTs and larger standard deviations of reaction times (RTSDs) would be observed in participants who scored above the SIMS cut-off (>16). Methods: Direct surface electromyography (EMG) was used to capture RTs during a computer-based RT test in 152 inpatients from a psychosomatic rehabilitation clinic in Germany. Correlation analyses and Mann-Whitney U were used to examine the relationship between RTs and SIMS scores and to assess the potential impact of covariates such as demographics, medical history, and vocational challenges on RTs. Therefore, dichotomized groups based on each potential covariate were compared. Results: Significantly longer RTs and larger RTSDs were found in participants who scored above the SIMS cut-off. Current treatment with psychopharmacological medication, diagnosis of depression, and age had no significant influence on the RT measures. However, work-related problems had a significant impact on RTSDs. Conclusion: There was a significant relationship between longer and more inconsistent RTs and indicators of exaggerated or feigned symptom report on the SIMS in psychosomatic rehabilitation inpatients. Findings from this study provide a basis for future research developing a new RT-based PVT.

Leptin promoter methylation in female patients with painful multisomatoform disorder and chronic widespread pain.

BACKGROUND: Different functional somatic syndromes (FSS), fibromyalgia (FMS) and other unexplained painful conditions share many common clinical traits and are characterized by troubling and functionally disabling somatic symptoms. Chronic pain is most frequently reported and at the center of patients' level of disease burden. The construct of multisomatoform disorder (MSD) allows to subsume severely impaired patients suffering from FSS, FMS and other unexplained painful conditions to be examined for common underlying processes. Altered leptin levels and a pathological response of the HPA-axis as a result of chronic stress and childhood trauma have been suggested as one of the driving factors of disease development and severity. Previous studies have demonstrated that methylation of the leptin promoter can play a regulatory role in addiction. In this study, we hypothesized that methylation of the leptin promoter is influenced by the degree of childhood traumatization and differs between patients with MSD and controls. A cohort of 151 patients with MSD and 149 matched healthy volunteers were evaluated using clinical and psychometric assessment while methylation level analysis of the leptin promoter was performed using DNA isolated from whole blood. RESULTS: In female controls, we found CpG C-167 to be negatively correlated with leptin levels, whereas in female patients CpG C-289, C-255, C-193, C-167 and methylation cluster (C-291 to C-167) at putative bindings sites for transcription factors Sp1 and c/EBPalpha were negatively correlated with leptin levels. Methylation levels were significantly lower in female patients CpG C-289 compared with controls. When looking at female patients with chronic widespread pain methylation levels were significantly lower at CpG C-289, C-255 and methylation cluster (C-291 to C-167). CONCLUSION: Our findings support the hypothesis that epigenetic regulation of leptin plays a role in the regulation of leptin levels in patients with MSD. This effect is more pronounced in patients with chronic widespread pain.

Neurohumoral Profiles and Childhood Adversity of Patients with Multisomatoform Disorder and Pain as the Leading Bodily Symptom.

OBJECTIVE: Patients suffering from chronic pain often present with multifactorial underlying conditions, sometimes without concrete pathological physical findings. Functional somatic syndromes (FSS) and somatoform disorders show a high prevalence of 8-20% and are often associated with adverse childhood experiences (ACE) and chronic stress. As many different FSS have overlapping symptoms, the concept of multisomatoform disorder (MSD) has been introduced as an encompassing concept. We hypothesize that a common neurohumoral profile is present in patients with MSD that is distinct from gender- and age-matched controls and thus provides insight into possible common underlying mechanisms. DESIGN: In 151 patients with MSD (138 females) and 149 matched controls (131 females), we determined ACE by the Childhood Trauma Questionnaire (CTQ) and chronic stress by the Trier Inventory for Chronic Stress (TICS). Furthermore, the serum levels of leptin, FSH, LH, cortisol, DHEA-S, and IGF-1 have been assessed. RESULTS: There were significant differences in the levels of leptin, FSH, IGF-1, and cortisol between patients and controls, mainly driven by female participants. Levels of leptin were significantly correlated with BMI in patients, in controls, and in the female subgroup. This correlation was exaggerated in female patients when compared to female controls. Both CTQ and TICS predicted MSD directly and indirectly through the levels of leptin. CONCLUSION: There is evidence of a distinct neurohumoral profile in female patients with MSD when compared to matched healthy controls, similar to what has been demonstrated in other chronic pain states. The observed profile can be taken as possible evidence for a dysregulated response to chronic stress and metabolic balance as well as a state of hypocortisolism and HPA-axis dysfunction. ACE and chronic stress play a major role in the development of MSD and altered neurohumoral profile.

Urinary excretion of IGFBP-1 and -3 correlates with disease activity and differentiates focal segmental glomerulosclerosis and minimal change disease.

The glomerular microenvironment is influenced by circulating growth factors that are filtered from the blood stream and pass the glomerular filtration barrier. In this study, we wanted to explore the role of IGF-binding proteins (IGFBPs) in two diseases that concern podocytes. We analyzed glomerular expression and urinary excretion of IGFBP-1, -2, and -3 in patients with focal segmental glomerulosclerosis (FSGS) or minimal change disease (MCD). We found that patients with active FSGS excrete high amounts of podocalyxin positive cells as well as IGFBP-1 and -3. In human podocytes, we can induce mRNA expression of IGFBP-3 in response to TGF-beta and in human microvascular endothelial cells expression of IGFBP-1 and -3 in response to TGF-beta and Bradykinin. We conclude that the local expression of IGFBPs in podocytes and endothelial cells might contribute to the pathogenesis of glomerular disease and that IGFBP-1 and -3 are potential non-invasive markers of FSGS.

Life-threatening course in coronavirus disease 2019 (COVID-19): Is there a link to methylenetetrahydrofolic acid reductase (MTHFR) polymorphism and hyperhomocysteinemia?

As the current COVID-19 pandemic develops and epidemiological data reveals differences in geographical spread as well as risk factors for developing a severe course of illness, hypotheses regarding possible underlying mechanisms need to be developed and tested. In our hypothesis, we explore the rational for a role of MTHFR polymorphism C677T as a possible explanation for differences in geographical and gender distribution in disease severity. We also discuss the role of the resulting hyper-homocysteinemia, its interaction with the C677T polymorphism and its influence on immune state as well as risk factors for severe disease. Finally, we consider possible dietary ways to influence the underlying pathomechanisms prophylactically and supportively.

Childhood traumatization is associated with differences in TRPA1 promoter methylation in female patients with multisomatoform disorder with pain as the leading bodily symptom.

BACKGROUND: The construct of multisomatoform disorder (MSD) is a common point of reference for patients in different somatic and psychosomatic specialties and therefore useful in studying large well-characterized cohorts of a prototype of a somatoform disorder and in parallel as a functional somatic syndrome (FSS). This disorder is characterized by distressing and functionally disabling somatic symptoms with chronic pain as the most frequent and clinically relevant complaint. Pain is perceived by nociceptive nerve fibers and transferred through the generation of action potentials by different receptor molecules known to determine pain sensitivity in pathophysiological processes. Previous studies have shown that for the transient receptor potential ankyrin 1 (TRPA1), receptor methylation of a particular CpG dinucleotide in the promoter region is inversely associated with both heat pain and pressure pain thresholds. In this study, we hypothesized that TRPA1 promoter methylation regulates pain sensitivity of patients with multisomatoform disorder (MSD). A cohort of 151 patients with MSD and 149 matched healthy volunteers were evaluated using quantitative sensory testing, clinical and psychometric assessment, and methylation analysis using DNA isolated from whole blood. RESULTS: We found CpG -628 to be correlated with mechanical pain threshold and CpG -411 to be correlated with mechanical pain threshold in female volunteers, i.e., higher methylation levels lead to higher pain thresholds. A novel finding is that methylation levels were significantly different between patients with no and severe levels of childhood trauma. CpG methylation also correlated with psychometric assessment of pain and pain levels rated on a visual analog scale. CONCLUSION: Our findings support the hypothesis that epigenetic regulation of TRPA1 plays a role in mechanical pain sensitivities in healthy volunteers. They further provide evidence for the possible influence of childhood traumatic experiences on the epigenetic regulation of TRPA1 in patients with MSD.

Parietal epithelia cells in the urine as a marker of disease activity in glomerular diseases.

BACKGROUND: The detection of viable podocytes in the urine of patients with proteinuric diseases has been described as a non-invasive method to monitor disease activity. Most of the published studies use podocalyxin (PDX) as a podocyte specific marker. METHODS: We examined the excretion of viable PDX-positive cells in a random set of spot urine from patients with biopsy-proven focal segmental glomerulosclerosis (FSGS), membranous nephropathy (MGN) or membranoproliferative glomerulonephritis (MPGN) and characterized the excreted cells for podocyte and parietal epithelia markers as well as for proliferation activity. RESULTS: We found that untreated patients with active disease excrete high numbers of PDX-positive cells in their urine. In contrast to that we were not able to detect significant amounts of PDX-positive cells in the urine of patients with active minimal change disease (MCD) and patients with FSGS or MGN in full remission. When we further characterized the cells we rarely detected expression of podocyte specific markers in the PDX-positive cells, but at least 50% of the PDX-positive cells were double positive for cytokeratin (CK8-18). Immunohistochemistry of the corresponding renal biopsies showed that 100% of podocytes and parietal cells stained positive for PDX. Semiquantitative analysis revealed that 45% of parietal cells were positive for CK8-18 and 100% of proximal tubular cells. No cells of the glomerular epithelial layer stained positive for CK8-18. CONCLUSIONS: PDX-positive cells are lost in the urine in disease states that require podocyte regeneration and are a useful non-invasive marker for glomerular disease activity. These cells are possibly derived from the parietal epithelial layer.

[Emergencies in Plastic Surgery: Analysis of Emergency Presentation within a University Department for Plastic and Hand Surgery]. / Notfallaufkommen in der Plastischen Chirurgie - Auswertung der Notfallvorstellungen einer Universitätsklinik für Plastische Chirurgie und Handchirurgie.

BACKGROUND: Interdisciplinary emergency departments in Germany are seeing an increasing inflow of patients for several reasons. Since the number of patients in the emergency room cannot be planned, there may be a lack of capacity with prolonged waiting periods and delays. In particular, a significant amount of capacities is consumed by hand injuries. Also it is suspected for the discipline of plastic surgery that the majority of emergency presentations are unjustified. We provide a collection of data followed by an analysis of emergencies to better understand the increased number of patients with the aim of identifying possible solutions for the relief of emergency care. METHODS: We performed a retrospective analysis of documented patient cases seen in the interdisciplinary emergency room of the Department of Plastic, Aesthetic, Hand and Reconstructive Surgery of a university hospital. Over the span of one year, we evaluated the diagnosis, waiting time and distribution of patients over 24 hours at 7 weekdays. Furthermore, we evaluated the justification of emergency presentation and the necessity of inpatient admission. RESULTS: We assessed a total of 2768 patients with an average age of 40 years (median = 37 years, male 59 %/ female 41 %) within one year (2016-2017). Of 2450 patients, 69 % were legitimate emergencies, defined by severity of trauma or disease. Proportionally, the most common cause of presentation for 2768 cases was upper extremity injury with cut and saw injuries amounting to 25 % (n = 697), followed by lacerations/bite injuries with 22 % (n = 611) and burns with 17 % (n = 477). Most services were performed between 09:00 a.m. and 01:00 p.m. There were no significant differences regarding the distribution over different weekdays. In 24 % (n = 583) of these cases, the patient was hospitalised for inpatient treatment. In 45 % of cases, there was no indication for hospitalisation after treatment. The waiting time for 2450 patients averaged 2:23 h (median = 01:43 h) until treatment. DISCUSSION: In face of these results it may be argued, that a majority of emergency cases could be selected through filter structures to be distributed to suitable facilities. This could cover a large proportion of the 45 % legitimate, but ambulatory emergencies. Furthermore a concentration of emergency departments should take place with a simultaneous supply of financial resources to expanding emergency departments with high patient flow.

Urinary podocyte excretion as a marker for preeclampsia.

OBJECTIVE: The objective of this study was to examine whether podocyturia, which is the urinary excretion of viable podocytes (glomerular epithelial cells), is present in urinary sediments of patients with preeclampsia. We also aimed to compare the test characteristics of podocyturia to those angiogenic factors that have been shown to play an important role in the pathogenesis of preeclampsia (s-Flt-1, PlGF, and endoglin). STUDY DESIGN: Serum angiogenic factors were measured in 44 patients with preeclampsia and 23 normotensive control patients. In a patient subset (15 cases and 16 control patients), urinary proteinuria were identified and quantified on the basis of their expressions of podocyte-specific proteins. RESULTS: Urinary podocyte excretion occurred in all patients with preeclampsia. The positive predictive value for the diagnosis of preeclampsia was greater for podocyturia than for any of the measured angiogenic factors. CONCLUSION: Podocyturia is a highly sensitive and specific marker for preeclampsia. It may contribute to the development of proteinuria in preeclampsia.
