Hyperthyroidism presents with various forms of generalized symptoms. Primary care physicians as well as other specialists should have this in mind when meeting patients with symptoms such as palpitations, sweating, fatigue and weight loss. Thyroid-stimulating hormone (TSH) is a highly specific test and useful in ruling out hyperthyroidism. The severity of the disease determines the pace of management. Primary care is often involved in detection of hyperthyroidism but also takes part in the work of rehabilitation and the lifelong hormonal substitution that is necessary for 2/3 of all patients. Subclinical hyperthyroidism, characterized by low TSH levels but normal levels of T4 and T3, is associated with increased mortality by 24 percent and risks of cardiovascular disease, atrial fibrillation and osteoporosis. Treatment depends on age, presence of comorbidity and TSH-levels. In addition to specific endocrinological treatment, person-centered care is crucial during active disease and rehabilitation. The first Swedish care program for hyperthyroidism aims to enhance care efficiency and equity.

Hip and knee arthroplasties are mostly successful procedures; however, patient injuries may occur and should be reported to Löf, the Swedish patient insurance. This study investigated the incidence of patient injuries after primary total hip and knee arthroplasty in the Swedish regions, differences in incidence depending on annual surgical volume, and types of approved injuries. Approved patient injuries were related to the total number of hip and knee arthroplasties registered in the Swedish Arthroplasty Register 2012-2021. The national incidence was 11.4 and 8.1 per 1,000 hip and knee arthroplasties respectively and varied in the regions from 30.4 to 4.9 and 15.4 to 5.4 per 1,000 hip and knee arthroplasties respectively. Orthopedic departments with higher annual volumes of performed arthroplasties had a lower proportion of patient injuries. Infection was the most common patient injury, followed by nerve lesions and mechanical complications. The differences may be due to underreporting and varying quality of care in the regions. A centralization of hip and knee arthroplasties may be beneficial.

To investigate the  clinical use of analyzing circulating tumor DNA in a clinical setting we present a pilot study comprising 93 patients from individuals with suspected lung cancer. The study aimed to evaluate the capability of analyzing circulating tumor DNA at the initial medical visit in order to detect genetic changes and mutations associated with lung cancer in plasma samples. Tumor DNA from plasma was extracted and analyzed with Next Generation Sequencing (NGS) and the result was compared with a matched tumor tissue collected in close connection from the same individual. Cancer-associated genetic mutations could be confirmed in about 60 percent of the plasma samples, and we observed a higher degree of conformance in patients with a more advanced disease. The results from the study provide valuable insights for an early clinical use of analyzing circulating tumor DNA in cases of suspected lung cancer, which could contribute to improving early diagnosis and treatment strategies for patients with lung cancer.

We present a patient with familial amyotrophic lateral sclerosis caused by an aggressive A4S mutation in the SOD1 gene. In 2020, the patient was enrolled in the VALOR SOD1 gene therapy phase-3 trial. At screening, the ALSFRS-R score was 41 (48 is normal) and the level of CSF-neurofilament L (an indicator of ongoing neuronal damage) was 11 000 ng/L (ref <650 ng/L). In the four years following enrollment, the patient received monthly intrathecal treatment with tofersen, an antisense oligonucleotide compound that inhibits SOD1 protein expression and hence lowers the synthesis of toxic SOD1 protein species. Side effects have been minimal and mostly attributed to the spinal taps. The patient remains ambulatory with an active social lifestyle. The ALSFRS-R score has in the past 18 months stabilized around 35-37, CSF-NfL is 1 290 ng/L and plasma-NfL is 12 (reference <13). This is the first documented arresting intervention in a patient with ALS in Sweden.

Increased molecular knowledge makes it possible to consider not only genetic defects but also expression profiles for precision medicine in advanced prostate cancer. Several prognostic and treatment-predictive classifiers for prostate cancer have been described, such as Prolaris, OncotypeDx, Decipher, Prostatype, PAM50, PCS1-2, and MetA-C, which all build upon transcript profiles. In research studies, the MetA-C classifier has shown clear prognostic information for patients with metastatic disease, in relation to outcome after androgen receptor targeting therapies, and so has immunohistochemical evaluation of tumor cell proliferation (Ki67) and PSA expression. Unfortunately, methods within clinical routine today do not allow molecular subclassification of prostate cancer. To enable comparison of the most promising treatment-predictive biomarkers and to evaluate the health economic value of implementing such precision medicine for prostate cancer, a prospective study is being planned as a joint initiative in Sweden that aims to evaluate and validate biomarkers and to establish a study platform for adaptive biomarker-driven clinical trials (sprintr.se).

The treatment of metastatic prostate  cancer has seen drastic changes in the recent years with more intense treatment at initial diagnose. The new standard is combination therapy with castration as the backbone and the addition of new hormonal therapies with or without chemotherapy. For patients with minimal metastatic spread it is also recommended to give radiotherapy to the primary tumour. Since many patients now can look forward to longer survival it is paramount to take care of the side-effects of the treatments, where focus is on cardiovascular disease and bone health management. Precision medicine has started also in prostate cancer; testing of BRCA1/2 mutation is mandatory for treatment with PARP inhibitors.

Prostate cancer is the most common cancer among Swedish men. To get this diagnose is not only a threat to the men's lives but also to their quality of life because the treatment often affects sexuality, bladder function and bowel function. It is therefore particularly problematic that the rehabilitation of men after treatment for prostate cancer often does not reach the standards set out in the national guidelines. Despite the past years' promotion of standardized cancer care pathways to speed up the process of investigating and treating cancer, the lead times for men who are being investigated for a suspicion of prostate cancer, or are waiting for a planned prostate cancer treatment, are the longest in Swedish cancer care. Patients' organisations are currently active in all 21 Swedish regions to support men with prostate cancer and their near ones. Their national umbrella organisation is increasingly involved in various healthcare organisations, such as the National Prostate Cancer Guidelines Group, and supports clinical prostate cancer research.

This article introduces a series of articles covering some of the most important aspects of contemporary prostate cancer care. After the introduction of the prostate-specific antigen (PSA) blood test and systematic prostate biopsies in the early 1990s, the incidence of localised prostate cancer and the use of radical treatment rose dramatically. Improved diagnostic methods and understanding of the tumour biology now reduce overdiagnosis and pave the way for organised screening. New and more effective treatments, in combination with the stage shift from advanced to localised disease at the time of diagnosis, have reduced the age-standardised prostate cancer specific mortality by half in men under the age of 85 years. The National Prostate Cancer Register of Sweden (NPCR) has evolved over the past 25 years and now comprehensively supports clinical care and is an invaluable research data source. Patients' organisations have emerged as important players on the national arena.
